Worst conclusions about 35 + years of errors on BGA Rework Stations approaches / selling / buying.
Pseudo-science & technologies
Nowadays “well-known, professional, Chinese manufacturers” use same copy / paste errors based in direct temperature transfer method. All, hot air, Black-IR, MWIR, Hybrid and so on techniques, use that world’s worst ever practice approach. At the world’s worst practice approach chapter, I’ll count here only few attributes. Highest ever inertia (that attribute, make that approaches uncontrollable on BGA Rework Stations).
The temperature transport medium (air – nitrogen) are the worst ever temperature transport medium (have the lowest thermal energy power transfer). In fact, the air (gases in general) are ones of the best thermal insulators.
The Black-IR (LWIR part of the IR electromagnetic energy spectrum), have some weird characteristics, low range of radiated pattern, huge inertia of the emitter (that fact make this type of emitter uncontrollable). You have another example from PDR-Rework aberrations about “focused light” Read more…
On the bottom heater (preheater, as philosopher guru’s name it), we will see the same world’s worst ever practice approaches. Nothing about how the science interpret the Tg – point, nothing about the methods that are empowered to heat a PCB. All “well-known, professional, Chinese manufacturers”, in same wrong path use hot air, hot nitrogen, Black-IR (LWIR), MWIR to heat a PCB.
These methods are the same methods that you’ll use in your cousin to make some popcorn, pizza or another food. In fact, the NASA use the hot air in his space lab to heat pizza, hamburgers and so on, are inappropriate on BGA Rework Stations.
The biggest crazy thing is that this pseudo manufacturers even don’t ask they himself if when I’ll change a resistivity on a PCB, I MUST preheat that PCB??? My opinion is that are not necessary. Any intent of heating (preheat) a PCB does only bad things, put in highly risk / danger the vias on the entire PCB / board. More about that aberrations… Read more…
Almost all (in fact all that use contact thermocouples), “well-known, professional, Chinese manufacturers” use the world’s worst ever thermocouple to measure the temperature among PCB (the BGA / component temperature they can’t measure with that contact garbage on BGA Rework Stations).
That thermocouple has a huge error, so… no accuracies. In fact that thermocouple is used on metal kilns, ceramics kilns or whatever another place where is needed high temperature / low accuracy temperature measurements.
From the entire thermocouples’ pallet, contact sensors pallets, all they are stacked on the world’s worst ever thermocouple type… The K-type thermocouple. They haven’t even common sense logics in their aberrational, approaches, use a thermocouple that can withstand more than 1200 °C on a 250 °C appliance. They completely ignore the lowest accuracies of that type of thermocouple type, the instability and huge inertia. Read more…
Some of the “well-known, professional, even some Chinese manufacturers” take in account that MUST read the real BGA / chips temperatures on a non-contact manner (in contact manner it is impossible to read the temperature due to the fact that you’ll move the chip / BGA from his place). For that reason, they “implement” the non-contact IR sensors on their garbage’s.
So far, so good. But all they that try these implementations completely forgot about a weird parameter that all materials from that world have… The infrared emissivity factor.
That infrared emissivity factor, it is present at all materials from this planet, and it is influenced by material type, color of the material, texture of that material. The worst thing is the fact that this emissivity factor can have a wide variation. That IR emissivity factor can vary from 0.1 to 0.96 in practice. So, a real temperature value about 100 °C, you’ll can read on a non-compensated IR non-contact sensor from 1 °C to 96 °C. Read more…
The Tg – point it is the greatest forgotten when we speak about BGA Rework Stations. That Tg – point represent not only what from scientifically point of view are defined as the point where the PCB goes from glassy like state to a rubbery like state. The Tg – point represent a flection frontiers between world worst ever practice and words best ever practice approaches.
That Tg – point is almost sure unknown for all “well-known, professional, Chinese manufacturers”. For more than 60 years all “well-known, professional, Chinese manufacturers” sell all over the world electronics product already destroyed from manufacturing stage.
Until these days, doesn’t exist at least one from a scientific point of view study that purpose the behavior of the vias on a PCB that are heated at 250 °C. Doesn’t exist same kind of studies due to the fact that all they “well-known, professional, Chinese manufacturers” doesn’t pay attention at the huge risk… Read more…
It is not important for all them “well-known, professional, Chinese manufacturers” that some standards say something about maximum 8 °C or ± 4 °C of non-uniformity of temperature among the entire PCB or BGA / chips. The standards are not made for them. They have their own non-standards on PCB heating zones.
Some of them use two zones heating popcorn machines, others (that are the majority) have three zone PCB heating pizza machines that try to sell us as “Professional BGA Rework Stations”. The stupidest “well-known manufacturer” try to sell us an artifact that have 64 heating zones. The winner is… KURTZ-ERSA with HR 600 XL, the “big” crap.
Only because they (KURTZ-ERSA) think that can, they want to be on top (they think in good part of that top), with not less than 64 heaters that they think that can individually control. None of them can control correctly even one PCB heating zone, the temperature MUST be very uniform among entire PCB. Read more…
All “well-known, professionals, Chinese manufacturers” stuck the board, the PCB in some fixed fixtures. That rigid fixture doesn’t let the PCB dilate and contract in function of temperature. As consequence, the PCB, the board will bend, and you will have the common occasion to try to mount a plane BGA / chip on a curved PCB / board surface.
That is one of the most common mistake that can be found on all world’s worst ever practice. But… A very interesting thing, appear after that I’ll start this informative campaign.
PDR-Rework!!! Change his fixed support to a some elastic support (that gentlemen’s discover the spring!!!). Nothing bad until now. But… They clearly demonstrate that have nothing to do with the science, with the technology, with the simple logic. They use only one spring in only one corner of their fixture! So if until now the PCB bend uniform… Now will bend… Nonuniform. That gentlemen’s are a miracle on illogics. Read more…
For the “well-known, professional, Chinese manufacturers” is not enough the fact that use the world’s worst ever approach to heat the PCB / BGA, they are using hot air for that purpose. But… They go further with the marketing aberrations in his aberrational fights to sell with any price BGA Rework Stations.
They observe that in the titanium welding are used argon (an inert gas) to prevent the rapid oxidation at high temperature of the titanium. Furthermore, they transpose that approach in BGA Rework Stations. As consequence way they think that with some inert gas, in that case nitrogen, they can prevent the oxidation of tin. Seems to have some logics… Or… not…?!
Not. On that particular process of a BGA soldering, the inert gas (the nitrogen) can’t flow between the BGA and PCB where are situated the balls due to a simple physically theory that say something about the fluids’ equilibrium. You can’t break that equilibrium when you blow from all sides nitrogen, air remains between PCB and BGA in… a perfect…equilibrium… Read more…
The second word’s worst ever practice approach is the Black-IR (LWIR). Many of the “well-known, professionals, Chinese manufacturers” use this type of direct heat transfer method. I’ll speak many times about direct temperature convection as the worst practice ever when we want to heat some materials.
As they (“well-known, professional, Chinese manufacturers”), doesn’t know or use the science or / and technology on his popcorn machines, they use the direct temperature convection with all inconvenient that this approach it has.
As they all are real artists in the use of the world’s worst ever practice, the use of LWIR are something normal for them. It is not important that this temperature direct convection is uncontrollable, it is not important that they achieve all aberrational reworks profiles, it is not important that have an interminable inertia. That truly is important for them is the fact that this method heat a PCB or a chip. It is not important if it is good or bad. Read more…
When I can think that the aberrations can’t be further developed, The “well-known, professional, Chinese manufacturers” make a step forward in front of my nightmare imagination and prove that the “universe and human stupidity are infinite” Albert Einstein.
Can you imagine the fact that if you must bet the first two worlds’ worst ever practice approaches, you can?! How??? Simply, you combine that first two worlds’ worst practice approaches in one! And invent the Hybrid technology.
And the winner… is… the BIG KURTZ-ERSA HR 600 XL!!! That guys set out to surpass all and everything in the world’s worst ever practice and approaches. From far they are my favorite in that stupidity marketing in selling with all price any bullshit. So… the KURTZ-ERSA are setting out the super mega hyper Hybrid to-heater that can burn all kind of materials. They have enough power both on hot air and Black-IR – LWIR / MWIR to heat any black material with IR and metallic materials with hot air. Read more…
Pseudo worst ever affirmations
That amount of the world’s worst ever practice approaches are the common denominator that represent all “well-known, professional, Chinese manufacturers”. As your easy can see, I put all that energumens in quotes and accentuate with bold and italic stiles this pseudo names on BGA Rework Stations.
That attributes, well-known, professional, manufacturers and so on, are self attributed from themselves aberrational illogical points of view. The worst thing ever is that nowadays you can’t trust in these words because these words were denatured. But in the same time represent a huge consumer / buyer attitude.
A huge amount of all that bought one or more garbage from that pseudo manufacturers, are buying from “well-known manufacturer” policy point of view. That policy is the worst ever policy when we want to buy something. We must be good informed, well documented before that we buy garbage like that. If not, we will pay the highest price, we can’t work with it. Read more…
As all they, “well-known, professional, Chinese manufacturers” can’t control their brain-less artifacts, they all invent the world’s ever weirds rework profiles. For they were not important, the flux, flux paste oxidation point, oxidation time. It is not important the time / temperature above liquid point of the tin that are manufactured the balls. In fact, theoretical rework profiles for all of them doesn’t exist.
Furthermore, for all “well-known, professional, Chinese manufacturer” it is not important to ask himself if the theoretical rework profile have any value, if that theoretical profile is good or bad, if it has any connection with the reality or the guys from JEDEC or IPC have something in common with the best practice in soldering on BGA Rework Stations.
The easy way is to pollute all internet mediums with all kind of stupid images, stupid advices, world’s worst ever possible practice, illogical points of view. Read more…
I’ll demonstrate all over this website that “well-known, professionals, Chinese manufacturers” are manufacturing all the world’s worst ever bullshits that the humanity can manufacture. All they are in the opposite side of all science and technologies, they are in the pseudo-science, pseudo technologies side of the manufacturing in BGA Rework Stations.
But, some of them have awards, PDR-Rework, KURTZ-ERSA, and any others I think. Who the hell and for what they give awards at that garbage’s?! The electronics sciences are changed without that, I’ll know?! What a type of energumens with amputated brain can be when give an award to one of that garbage?!
Somebody on that awards company are able to think?! Or the awards can be bought?! If the awards can be bought, I want to buy a dozen to put them in the WC, for cleaning purpose. Can you imagine that the PDR-Rework have awards (two consecutive years if I remember correctly)?! Read more…
Almost all “well-known, professional, Chinese manufacturers” have one. Have one “IPC Certificate”. Until some time ago, I was happy with my more than 35 years in the electronics service, reverse engineering fields. But, with some times ago, when I start the garbage / bullshit documentation, I see some strange logos on many of the websites that I’ll read on BGA Rework Stations.
These logos are the IPC logo. That logos have a special place on any of the websites that use them. All they use that logo’s to prove the “quality” of their products. So… for me was another unproved affirmation. As I’ll was accustomed to unproved affirmations, I’ll start some small researches to see what is that IPC.
What I find about IPC, for me, was incredible. In some few words, for me seems that the IPC are one of the oldest pyramidal game ever. Some salesmen’s affirm that they teach the electronics professionals… electronics. The stupidity of that affirmations let me down. It is impossible… Read more…
As “well-known manufacturers“, the “Chinese manufacturers” catch that business on the fly. They start with the niche that almost none “well-known manufacturers“, the under $10,000 niche. Here on under $10,000, exist only few “well-known manufactures“, Zephyrtronics, some Pace and whatever else that can’t cover that niche.
As the Chinese are well-known to copy / paste all kind of technologies in the world’s worst ever practice approach, they continue their stilling abilities in that tools, the BGA Rework Stations.
With their money hungry policy, they can “manufacture and sell” popcorn machines as low as $200. After that, they cover the entire lowest that $10,000 niche, give a shot at greatest desires and start fighting at all price levels with “well-known manufacturers“. That attitude is normal and predictable. They can copy and paste, cheaper, all errors from that world. Read more…
That part is one of my favorite part from all aberrational parts that I’ll discover all over the internet. On Google first pages, you can encounter plenty of gurus, you need only time to read all aberrations about electronics. But as Einstein say…
“Only the universe and the human stupidity are infinite, I have some doubt about universe…”
The stupidity populate about 99% of internet. The worst case for us that are not stupids, it is the time that we’ll spend on our interminable searches for some real and usefully information that on some place on internet exists. We are condemned to interminable hours spent in front of the world’s greatest stupidity invention. The internet. When we’ll invent the internet, even in our worst nightmares can’t imagine what the internet was after about 20 years in the future. Never ever I can understand so many peoples are so stupids in same time, same universe. But from that stupidity, some guru’s win a huge amount of money. Read more…
Searching BGA Rework Stations on Google are equivalent with a suicide. That was for me on 2012 when I’ll do for the first time a search to buy a real Professional BGA Rework Station. I’ll read at that time all and complete information from hundreds of webpages, websites, all that from “well-known, professional, Chinese manufacturers”.
At that time, I’m was somewhat flower-power, I’ll think that if Fluke, Techtronix and another big names exists, almost sure that exists some big names in Professional BGA Rework Stations. When I look now at past times, I’ll see what an ignorant I was at that moments. Due to the fact that so much information from so many places was the same, I’ll was tempted that are true.
It is incredible how in a some kind of parts from science and technology can be, all over the internet only pseudo-science, pseudo technology, world’s worst ever practice approaches. It is incredible how doesn’t exist even one … Read more…
As the artificial intelligence touch all doors from entire world, I’ll give it a shot to ChatGPT to see if their artificial intelligence reaches the fly intelligence level at least. My dialogue with ChatGPT didn’t surprise me. The logic behind that artificial imbecility is simple.
The training that ChatGPT have until now are clearly from Google. On Google are all and only imbecilities ever wrote. So… The ChatGPT are trained with imbecilities that all of them can find over the internet about BGA Rework Stations.
So… The hope to discover something new on artificial intelligence are zero. Will have a long, long way to correct all that pseudo-sciences, pseudo technologies, aberrations and so on that nowadays are training our beloved artificial intelligence. Until that, I need some artificial intelligence on my control software and now, I know how I must not do training them. With time and hope for a long time in the future, it is possible that… Read more…
Using big names, consecrated names in electronics industry without their knowledge are not only immoral, but it is against the international laws. If you do a simple search all, “well-known, professionals, Chinese manufacturers” use with intentions to convince potentials buyers, big names like;
NASA, Intel, Xilinx, Bosh, Phillips, Honeywell, HP, Ford and so on. I don’t know if that names known that their names are used with intention to sell garbage. I’ll bet that they don’t know that facts. In fact, it is so many places on the internet that can’t be really controlled that the same approach is almost a banality.
So… If you’ll see on the garbage manufacturers websites that approaches, you must don’t pay any attention. All that things are fakes. If somebody tries to demonstrate that the pseudoscience = science… Be my guest, I have no time for that bullshits. On my websites, you’ll have my opinions. If in the future will appear some real professional manufacturers I’ll be very glad. Read more…
Pseudo well-known manufacture
I’ll start with PDR-Rework from the simple fact that in the past, I want to buy one garbage like that. At that time, I was ignorant. Initially, I see that they are the black sheep from that amputated brain heard of “well-known, professional, Chinese manufacturers” on BGA Rework Stations.
At a first superficial point of view, their approach catches my attention. In fact, between all that heard of amputated brains, PDR-Rework it is the only one that has some intuition about the world’s best ever practice approach, about the part of the electromagnetic energy that is almost the best practice approach to heat something in BGA Rework Stations.
The NIR / SWIR and some MWIR. But here (at intuition chapter), their luck is ended. The pseudo scientifically, pseudo technologically the world’s worst ever approaches, cancelled their initial intuition. The PDR-Rework are the clearest example when we’ll speak about aberrations. Read more…
KURTZ-ERSA, the second review that you’ll must read. They have the “well-known – professional” HR 600 XL at higher price that a well tuned Mustang – $110,000. At least one specimen of that overpriced popcorn machine was sold to a USA company that were very proud with his acquisition of BGA Rework Stations.
This is a clear example of brainless “well-known manufacturer” buying approach and spending on the wind $110.000 from a company packet. I’m pretty sure that the guys or girls that do this acquisition were promoted to more important jobs.
But… for you, that only dream for the moment to spend that amount of money in the more expensive garbage from today market, before that, you can take a look on the special page that I’ll write here, and be well documented, good informed about what they sell at Ferrari price, garbage, that as they are “well-known, professional, Chinese manufacturers included” it affords to sell you with all lies, cheating and so on. Read more…
In a country that put the man on the moon, in the country that is the spirit of democracy, exist PACE. That fact represent the power of that democracy, even in the USA exist “well-known manufacturer” that compete at world worst ever BGA Rework Stations title.
Like PDR-Rework, KURTZ-ERSA, Pace claim tradition (60 years) on electronics soldering industry. The only thing that they learn in that 60 years are the prices. Well… Pace are the only one “well-known, professional manufacturers” that have the prices on his website.
God save our souls, what a price it has for some huge overpriced popcorn machines, pizza machines, Santa Claus cousin. For me all, but all “well-known, professional manufacturers” remain a black hole. How can they all imagine that they can sell the same garbage that are manufactured by Chinese manufacturers at a fraction of their prices?! But… The Chinese manufacturers catch the policy and manufacture / sell their garbage… Read more…
Finetech – another overpriced garbage manufacturer. Over all… Finetech buy Martin “technologies” to sell not the weird ever sounds but the weird shape ever. Now the Finetech have the portfolio complete in his fights for the world’s worst ever practice approach on his selling fights in the “well-known manufacturers”.
Finetech has the brilliant idea to copy / paste the world’s worst ever practice approach from Zephyrtronics, the “air bath” aberrations. Not only that, the Finetech copy that aberration but took that to the next level. They invent… “air bath jacuzzi”. So that assure you that your PCB will die in a dignified mode, in a jacuzzi of.
Personally, I can’t stop to ask me what a hell can exist on the head of that gentleman’s?! They all think that all we are only professional ignorant’s?! That gentleman’s think that all we have the brain amputated?! Or (almost sure) that they think that all are good enough to be used in the electronics soldering process. Now the wave of ignorance is broken. Read more…
Zephyrtronics – another big shame for the honor of a country that put the man on the Moon. In fact, they are the biggest shame for the USA. Not only that they manufacture the world’s worst ever “BGA Rework Station” on this planet, but… Claim that the NASA use their garbage to manufacture satellites, Mars rovers and so on.
If that fact it is true, I am a priest. That levels of manipulations, lies, cheats are not encountered on any other garbage manufacturer. I ask myself if the NASA know something about that attitude that this gentleman’s use to sell garbage’s with NASA logo on them. I’ll bet that the NASA are ignorant about that on BGA Rework Stations.
Put on same level, the PCB heating with 400 °C when the Tg – point are between 135 °C to 250 °C represent the world’s worst ever practice approach, and NASA world’s best ever practice approach on any of their projects, for me are the world’s best / great ever aberration possible. That is the best example on how MUST not be manufactured a tool and publicity for that tool. Read more…

That aberrations you’ll meet on the homepage of this garbage manufacturer. They are proud that manufacture that garbage in the USA. Nothing bad until now. The bad thing is that they lying / cheating you with the affirmation that their garbage are part of “Professional BGA Rework Stations”.
In fact, they are in the same usual path with Zephyrtronics, Pace and more garbage manufacturers that are proud to manufacture garbage in the USA and KURTZ-ERSA, Finetech… Read more…
