How to make a homemade BGA reflow soldering station / home made video chip rework machine
HTML-код
- Опубликовано: 11 сен 2024
- The following video is about a home made BGA soldering station. Pay attention that some of the most important things on it are to control the temperature ON the chip we are working with (or next to it). Another is to use a bottom preheater and also to find the way to reproduce the BGA reflow graphic. I used two step temperature controller and I added a pedal to help to integrate the temperature rising slope and to match my graphic to the BGA reballing chart.
If you liked the video or if it was worthy to you, don't forget to give a LIKE. You can also join the Channel for more interesting videos about electronics workshop.
Thanks by watching it! :-)

Im an american. In the first minutes of your video I learned more in those moments than I had watching hours from other videos covering this topic. Thank you.
Thank you Bob, glad to hear back from you and I will be looking forward to watching and learning as muck as I can from you and others that spend your time to help. Thanks again Aron
I wish i was smart like you sir. Im trying to learn electronics repair.
Fantastic work station, and great idea!
good work! I'm receiving a couple CPUs this week where I need to remove the Integrated Heat Shield from. The Heatshields are soldered on with an Indium Alloy (melting point around 140-157°C). I only need to remove the Heat shield, not solder anything on. What do you think is the appropriate profile for this? Just preheat to 120°C to remove water, then go to around 160°C until the heat sink can be removed with tweezers? Thanks for any comments and keep up the great work!
Hola Bob, me parece muy buena tu solución, he visto varios de tus vídeos y me han servido mucho, el material que compartes y la forma de explicar es Excelente, te quisiera sugerir algo, podrías dividir tus vídeos en 2 canales, uno para el material en inglés y otro para el de español. En mi caso entiendo el inglés pero creo hay mucha gente que también podría aprovechar tus vídeos. Te felicito por tu canal y espero sigas subiendo más material. Saludos desde México.
Very good ideas and explanations. Keep up the good work
So professional
Hola! Your English is very good! Even tho your setup isn't real high tech, it definitely works! Thanks for explaining the heat cycle/profile schedule and timings. Do you have different tips for the hot air gun? Wish you could have done a board!
Nice design, Can you show us an example how it performs. Thanks again for all your videos.
Excellent tips !
very nice i like to see that you used your brain and found a work around to having all of the special equipment. I have been trying just what you had shown, finding 1 to week and 1 to powerful, this is just what I did with just problems. this is very helpful. Thank you very much. If at some time in the future make a video of how to assemble your machine with the time and power controls and how they are wired please let me know . thank you again, Aron
Hi! Thanks by writing.I will make some videos in the future about how to make more sophisticated machines. This one is a very easy one, but with enough controls to perform good job, and it can feed most beginner's budgets.
I made very sophisticated machines in 2001 as a process and designing engineer... But now, as new immigrant with small baggage, I had to do it as a lot of you guys did it around the world.
There will be more videos about homemade BGA and SMD stations, and some basic lessons about to the right way to do it. :-)
This is great! Now I can fix LG's mistakes!
dear Bob. Kalpon, will you please provide me with the wiring or schematic diagram so as to be able to construct this project properly, any help would be appreciated thanks
Hola Bob, el pedal controla la temperatura del rework y del preheat, o solo del rework¿ las temperaturas de ambos elementos de calefacción deben aumentar iguales en la grafica o la del preheat se mantiene a una temperatura menor¿ Gracias
good job
Hi, do you have a video of it in action?
Gracias excellente!
Hi Bob, nice job do , would like to do the same station, do you have some schematic?
I need more information in order to do.
What is the there profile for recalling PS4?
Hola , let my know the link of demonstration of your rework wok station..thanks in advance!!!
Hi Bob..this is great project .needed nozle for heat gun ???
Yes I use a reduction. It is not special one. It is one from the original heat gun package.
Thanks
You are welcome!
De donde es originalmente y en qué parte de Europa está? FYI: I started watching and subscribed because I was taking a crash course in electronics before job interview :)
Hi! Good luck with the job interview!!! Write to me in Facebook it is useful for any technical question.
Good job.but i dont get do you use foot paddle turn off heaters
Hi! This machine is very rudimental. Temperature is a profile that requires 5 different controlled levels. The best way is to use a micro-controller. If we can't use a micro-controller, then we can use a pedal to alternate the heater on and off, and try to keep the expected temperature in the termocouple.
thanks
Any idea of the total cost?
Hi, Bob excellent but it's not for RoHS product graphic chart good job !
Hi! The chart id for 63/37 solder. For RoHS is higher temperature than it. Now days the fashion is RoHS because the new agreements about pollution. I used the chart because its six temperature-times illustration.
Hola Bob, en Español por favor ;)
Hello, I would like know how prepare temperature profile when chip has operation temperature is 80 degree C? Thanks for support and explain how I make this the profile.
Hi Tomas. The operation temperature is something different to reflow temperature. Your chip works hours or years close to 80 degrees and it shut down by safety after it. The soldering temperature in SMT process goes to a peak of 217 or 245 degrees for just few seconds. To make a good solder SMT profile for build, we must consider the components datasheet, and the solder datasheet too. To make a rework temperature profile for repairing, requires more strategy like covering or removing THP components.
Hi Bob. Thanks for support , My question was on working temperature because is in datasheet but rework|soldering temperature no and I afraid overheat BGA " popcorn efect " chip eg. 130 degrees like preheating DPS and then about +50 degrees/10s +40/5s = 220 degrees.
@@tomashasoft4938 Aha! That´s the most important part. There is not way in Electronics Manufacturing SMT process can start if components didn't accomplish the oven baking process. I never work in cold, or high humidity. I learned from one old fox in the 80´s to leave the components in a box with a 100 Watts lamp for one or two days as minimum. (It also for the equipment out of use for a while. It was in a tropical country with very high humidity). Pop effect is not because temperature out of range, but for internal humidity. The best way to rework is to bake the component one day before even it is at lower temperature, (Bad advice but better than nothing), and preheat the under area before to rework. In this case, hot air can be the best. But for a single component like capacitor, resistor, small transistor, the soldering iron works fine as well as we rate less than 10 seconds in the melting point. There is more to consider depending of the need and rules. For aerospace manufacturing, hot air reflow in electrostatic air control at 100% of the solder process is required. (There is not iron, and nothing alike can make contact with the components). But it is other telling and teaching for those needs.
hi when will you star with the reballing machine proyect. a lot of people is waiting
+Raul Morel Hi Raul. Yes, you are right. I am working in a project about. I want to make a machine that will correct automatically several problems and difficulties. Give me a chance. We, all of us, will get the "smart machine". :-)
+Bob. Kalpon thanks man GOD bless you
Good job would please provide me with wiring diagram
Gracias. Neccessito aprender hacer BGA's. En ingles dicemos "Gun" no es Pistol... Pero pistol es un tipo de poco gun. Heater Gun o Hot Air Gun como escribe en la caja. "Graph" no hablamos graphics. Tu ingles mejor que mi Espanol/Castellano.
Hola! Si bien USA, UK, España, India están entre los diez primeros países de mi audiencia, la gran mayoría de la audiencia no son de habla inglesa y hablan algo que conocemos como "broken English". El asunto de enseñar no trata de lucir como catedrático ni tampoco en español, si no de poder hacerse entender para que el educando pueda aprender con mayor facilidad. Me verás haciendo lo mismo aún en español, pues Filipinas está entre los diez primeros países de la audiencia y su actual generación apenas comprende lo más básico del español heredado de sus abuelos. Hay audiencia de Brazil, Portugal y Romania, quienes ven mis vídeos en español intentando aprender de algunos de ellos. Por otra parte, más del 50% de toda la audiencia la componen países árabes y Asia Menor a quienes hay que llegarles con un inglés más lento y acorde a sus limitaciones. Otro limite es que muchos son técnicos o aspirantes a reparaciones, por lo que aún no incursiono en temas de ingería o fórmulas de cálculo. Gracias por la corrección de todas formas.
Deberias haber hecho el video en castellano y haberlo subtitulado en ingles.
+Fernando Ariel Hi! I will make another videos. Spanish is not an easy language, and there are few people interested on this kind of videos. English is a technical language that people from any country can listen and understand . But I will ad more videos in Spanish soon. :-)
I can translate it for you if you want, and I could send you the subtitles...
porfavor este sacarlo en español también
Si ofender,pasalos al español,que tu ingles no es bueno y menos el traductor de youtube,muy buenos videos tenes.
Su ingles no es problema uno o dos palabras no tipico.. Pistol=Gun Graphics=Graph. Es claro. Mi lengua es ingles pero cuando trekking en sur america hablo castellano.
good job
Hola Bob, en Español por favor ;)
