BGA Rework Station - the superlative of Rework & Reflow
BGA Rework Station, rework and reflow process, and more on what exists in the market versus what we need in our professional activity.We are proud to be an American company since 2012, with services on five continents. For over 35 years, we have promoted the world’s best practices, science, and technology. On this website, you can stay informed, use the world’s best tools/standards/practice/approach, and be a big part of the most significant part representing the world’s real professionals in electronic sciences.
ATTENTION PLEASE
Here, on i-esn.com and iESN L.LC., all collaborators it has a Ph.D. in what seems to be the most accessible, most common, used, known basics technology, the electronics soldering process. Suppose you are an engineer with a master’s in electronics and think that you don’t have anything to learn more about soldering in electronics, that you buy the tools by “well-known manufacturers” policies. In that case, this website is not for you. You can go to whatever else place, save your time for the moment. You will return later when you spend money on tools that are not tools, don’t work, and can’t use them. For all other readers of this website, please prepare your patience, attention and open your mind.
Read all information on this website with patience and attention; on the final, please draw your conclusion about the electronics soldering process.
Here, on i-esn.com and iESN L.L.C. We don’t think we are best or worst than any other company or website. We are only different. We don’t believe that our projects/products are the best or worst than other manufacturers’ products. Our projects/products are only different. What we think is the fact that our approach is the best that all other world’s worst ever approaches. Our systems are the best because our projects/products use the world’s best practices and honest, professional scientific, technological, and logical points of view. All other world’s worst-ever practice approaches use the pseudo-science, pseudo-technology, and illogics points of view.
We have common sense. Common sense says that the best practice is better than the worst practice. For that reason, we think that our approaches are best than the worst ones.
We are very sorry to inform you that the real Professional BGA Rework Station wasn’t invented yet. All pizza, popcorn machines, Santa Claus cousin that are sold on nowadays world market are not a BGA Rework Station. Before buying one or more artifacts like this, we must be informed. All they use the direct temperature conduction approach, the world’s worst ever possible approach. They lie, cheating, misinform, invent aberrational processes, invent / have awards, do all they need to… Sell.
Over all, all, they use the direct temperature convection method (world’s worst ever approach). We are amazed about how an entire humanity can be ignorant, we are amazed on how in this world, was possible that almost 40 years are used world’s worst.
From three type of energy transfer method, convection, conduction, radiation, only one it is the best practice approach, that is radiation, direct electromagnetic energy transfer. That approach send to the object that must be heated, an energy spot, the object absorbs that energy and convert that energy in heat on that named “self-heating”. That’s the best ever approach.
Unlike in above approach, all… but all “well-known, professionals manufacturers” use the world’s worst ever approach method. The direct temperature convection method. They use that method because it is the easiest way to heat something, like a pizza, popcorn machines. The big lack of that approach is the inertia, that inertia is huge and uncontrollable.
All “well-known, professional manufacturers”, in their money hungry competitions, completely ignore the most important aspect of a PCB – board. That most important aspect have a name, Tg – point. This Tg – point represent the frontier where the PCB – board change his proprieties, his states. Below that Tg – point (from temperature point of view), the PCB – board are solid (glassy state).
Above that Tg – point, the PCB – board change his state from glassy to rubbery like (somehow elastic) state. That state apply a huge deformation force (expansive force), that put on highly risk all vias on that PCB – board that are heated above Tg – point. That is the world’s worst ever practice approach.
From the world’s worst ever approaches come the hot air / nitrogen capable “tools”. For us, it is a huge shame that the hot air make part from “tools” that can be recommended for use in soldering. It is an offense for all that use best practice approach in electronics soldering. They don’t have at least common sense when use hot air.
Hot air, hot gas (nitrogen), “Black-IR” – LWIR, MWIR, are not approaches that are recommended in electronics soldering best practice approaches. That technologies that are use by NASA in space, to heat the pizza, hamburgers, must remain on that place and not be used in the highest qualified, highest performance soldering process in electronics.
For more than 40 years, the electronic assembly part of the electronics “professionals”, use reflow ovens alternated with “vapor phase” pseudo technologies. The worst ever approaches possible when speak about a so highly qualified, highly complicated assembly process. Like a pizza or popcorn machine, but with a huge scrap percentage.
The electronics assembly part of the professional world must open his eyes and think about best practice approach, about energy consumption approach, about space ergonomics and more. They have more than 40 years with no thinking approach. After that yeas of promiscuity, ignorance, world’s worst ever practice, it is time to.
When came some salesmen’s on our company to learn us soldering in electronics, we will close the company. When we must respect IPC standards that speak about BGA Rework Stations (the BGA Rework Stations are not invented… yet – doesn’t exist), when we have to respect standards for something that not exist, we will close the company.
Furthermore, when we will hire at somebody only because it has IPC certificates, we will close the company. When we will be inutile with IPC certificates, we will close the company. Until that we will close the company, we will patent the … paper roll with the IPC logo & certificate on them. That’s all, are promises, and we always respect our promises.
Google has turned into a jungle. Last time when we documented about what we can buy (BGA Rework Station / Reflow oven), we realized that Google change it into a real jungle of infinite number of energumens. So many aberrational advices from a part of so many illiterates gurus, the only aberrant affirmations (without any proofs at that affirmations), so many recommendations from a subunitary IQ (IQ<1) guys, so many pseudo-science, so many pseudo technologies.
Google it is now only a money making machine, a real adventure where you’ll can buy the worst ever tools in electronics soldering based on the worst ever.
I had the chance to read the conversation that it has, a colleague with ChatGPT (artificial intelligence) about BGA Rework Stations, rework process and reflow process. I was terrified. That guys that invent ChatGPT were able to join absolute all aberrations, ignorance, pseudo-science, pseudo technologies, subunitary IQ, guru’s, absurd affirmations…
All that in one place. If that approach of artificial intelligence continue, on the year 2150, yours great-grandchildren will buy the next generation of the actual aberrations with… artificial intelligence (God bless our souls) implementation. We all must study some forms of collaborative attitudes to kickback all that nonsense on the best practice path.
Axiom – 1 – To heat an PCB / BGA or anything else in electronics soldering process, must be used direct electromagnetic energy transfer. In that way, when our PCB / BGA / RF-shield, receive that electromagnetic energy, will absorb it, and it converts in heat, self-heating the component or PCB. That approach give us the finest control of the process due to his lowest possible inertia process.
With direct electromagnetic energy transfer approach, with the smallest ever temperatures’ error (NIST traceable certificates) with the finest ever – AI assisted Fuzzy Logic PID control, the 100% yield, 100% repetition rate are warrantied. That mean world’s best ever approaches in soldering.
Axiom – 2 – We need some (about some thousands) perfect shapes from 5 mm to 80 mm (80 mm seems to be the largest BGA nowadays), in perfect square / rectangle and round (& round not only round as you can see at one “well-known” manufacturer). We need that perfect shape due to the fact that we will meet some (250 W to 1000 W) of consumed power to heat our BGA / component / RF shield and so on. No supplementary nozzles’ technology, in all possible shapes is mandatory, it is a MUST.
That represent the world’s best practice ever approach, and represent us and you, the real professionals, in our daily activities. And of course, the 100% yield / 100% repetition rate in Paris, Tokyo, New-York, London.
Axiom – 3 – The uniformity on entire surface (corners / middle) of BGA or component or anything else, must be close to perfection. Any errors on the uniformity will generate the worst ever soldering / un soldering process. For example, when we try to un solder a BGA. If we have an un uniform heating over the entire BGA, where the balls are not fluid, it will break the trace and vias. Where the balls are fluid, that balls will break the tin and will not break the trace.
That mean best ever practice approach, that mean real professionalism, the respect of science and technology, make us to believe in our skills, over all give us the possibility to have 100% yield, 100% repetition rate.
Axiom – 4 – PCB – board temperature uniformity. That is a must. The uniformity of the PCB – board will give us the starting point in what, later, will be the best ever practice approach. A PCB – board must be very uniform self-heated, never ever above the Tg – point. The uniformity and the Tg – point are the two most important parts of that axiom.
If we are in another place that electronic manufacturing (electronic repair, for example), we almost never know the Tg – point. A must-do is never ever heat the PCB – board over 100 °C (Tg – point can be wherever between 115 °C and 250 °C). When we’ll heat the PCB above Tg – point (Tg – point – the temperature where the PCB goes from glassy to rubbery like state).
Imagine that for about 20 years or more, exist the technologies, exist the science that are able to respect best ever practices approaches. But none uses that technology. With this simple technology, the consumed power can be less than 1 kWh to complete solder a PCB about 1 m / 1 m in less than 30 seconds under 80 °C. Why nobody uses that technologies?
Why the “well-known, professional manufacturers” use the world’s worst ever technologies for more than 40 years that have an installed power about 150 kWh and “reflow” same board in 5 minutes! Something escape to our logic. Are they a simply… ignorant?! 1 kWh – 30 seconds / 150 kWh – 5 minutes?! For more than 20 years?! In what a world are we living?!
The normal / logical pathway, first have a tool that respect a specified standard NIST.gov, for example for temperature (world’s most famous / accurate standard’s provider). After that (have a NIST traceable certificate), this tool must comply to some best practice approaches (I’ll write above about that). After that, this same tool must comply to some common sense rules.
Furthermore, after that all above are complied, well you can join an electronic professional team to make a standard. For us, that is the logical way. Well… Nowadays, are enough to have some paper and a logo on it to have a “professional certificate” for the world’s worst ever practice approaches.
Google, it is a jungle. That it is a proved fact. If we want to learn / understand things about best practice approaches in electronics soldering, we must start with the worst ever practice that we’ll find on Google. In fact, all that we find about soldering, selective soldering, reflow are worst practice.
If we have time, we must dig in deep on Google about science. That it not an easy task, but with patience / time and money, we’ll find the science and technology. After that we find the right path, the science, technology, common sense path, well… we think that we can manufacture our own BGA Rework Station, for example. Wrong, we need money, a huge amount of money.
Pragmatically speaking, the Artificial intelligence nowadays have the IQ of a fly. Will pass many, many years to achieve the IQ of a newborn baby. Actually, the AI are in the learning path. It will be a long, long way until AI will be able to… Think. For the moment, Artificial Intelligence have the IQ of a fly. It will pass many, many years until the AI will have the IQ of a newborn baby.
AI can be useful on small scale explicit tasks. For example, the AI can be successfully used on our projects, BGA Rework Stations for example. We are able to lean on AI from past errors, for example that it is bad to heat a PCB above the Tg – point. In that manner, our BGA Rework Station with AI assisted Fuzzy logic PID, will never heat a PCB over 100 °C.
At a first view, from a commercial point of view, seems that nowadays electronics manufacturing market necessities, are completely covered with “well-known” manufacturers, so… no hole / niche can exist. But when we analyze from scientific, technological, best practice point of view, we’ll see the simple fact that what commercial exist doesn’t respect that criteria.
Simplifying that analysis – what from commercially point of view exist, from scientific, technological, best practice doesn’t exist. That mean that an unexpected black hole exist, that last for more than 15 years and nobody seems to try to cover it, letting us a huge opportunity / niche in an already formed consumer market. The place of the world’s best practice approaches. Read more…
The correct identification of the problems that an entire electronics industry have in selective soldering (BGA Rework Stations, selective soldering in general), with nowadays approaches, based only in money, the worst ever approaches. That’s approaches give us the possibility to implement the correct approach as solution that are the targeted on that niche market goals.
As none exist in that kind of scientific / technological / best practice approach market, give us a complete empty market shunting field. That empty market, let us many wide best practice approaches to implement new, novel technologies based on science and technology. Read more…
For more than 40 years, the electronic assembly part of the electronic industry, use the world’s worst ever approaches possible. The first short examples are the reflow ovens, that reflow ovens use what is named “direct convection temperature transfer“, the world’s worst ever practice approach.
A second short example is “vapor phase” approach. That approach is the second world’s worst ever approach when we’ll speak about electronic soldering due to the superficial tensions in fluids. The superficial tension on the liquid condensed from the vapors, mismatch the fluid tin. Both world’s worst ever technology have very simple alternatives based on science and technology. Read more…
When we look in the standards, trainings, certifications markets we’ll see some very strange, worst behaviors. We can see that many “well-known, professionals” manufacturers, use in their false marketing fights, a badge with “IPC Certified” manufacturer (company). So, we have a manufacturer that use the word’s worst practice approach ever, certified by IPC Certificate. That kind of thing is at least weird if not anything else.
If we take a look at who is that IPC, we’ll see that IPC, have a certificate / certifies a tool that doesn’t exist! In consequence path, the IPC (that claim quality, best practice, standards and so on), are in an existential paradox of his illogic existence. Read more…
When an entire world, from more than 40 years, use the worst ever, wrong technology, that is the first opportunity to correct this path in the best technologies practice approaches. The second opportunity consists in the lack of best practice approach standards. The same, exist opportunity to correct that worst ever (nonexistent) standards in world’s best ever approach standards, made by real professionals for real professionals in electronic sciences, not by some salesmen.
Third opportunity is the fact that all worst ever practicians (well-known manufacturers, IPC certificates, and so on…), are training persons in that worst ever skills only for money. The dream that someone can learn electronics science in 3 days… Read more…
To change the world’s most highly specialized industry, it is the highest challenge can ever imagine, a proud and a real honor. This challenge is hard, it will have a long way, will involve a lot of human and financial resource. To cite at John Fitzgerald Kennedy,
“We choose to go to the Moon… We choose to go to the Moon in this decade and do the other things, not because they are easy, but because they are hard; because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one we intend to win, and the others, too.” JFK and many other leaders open / shown the path for us to follow.

All nowadays “well-known, professional manufactures” make all kind of affirmations about the facts that they have best practices, the best trainings, best tools, best, best, best… IPC certificates! In fact what the real world demonstrate about their affirmations is the fact that they use the world’s ever worst practice approach, the real world demonstrates that all they use illegal bad practice (false, fake advertising), false, misleading marketing. What we write here represent an affirmation for us.
On this website, we will argue / demonstrate all that affirmations. We dismount all word’s worst ever practice approaches, remounting them in the world’s best practice approaches. Read more…
All, above, was transformed in many projects. From a theoretical point of view, all projects are finished. Next step is the practical point of view approach of these projects. Many of that projects are passed the alpha stage (research and development from scientific / technological / best practice approach, point of view), and now about four of them are in the beta stage, the last stage before the final product.
In the same time, we make public our presence on the internet jungle. Please read complete, with patience, all information on this website. Of course, we expect that you, that are a real professional, will be a big part of the biggest part of world’s real professionals that apply the simple and mandatory, common sense rules. Read more…
