Wow first video I've seen showing the 'trade secret' by reflowing the processors. THANK YOU for making this!! will save a lot of Saabs :)

[@NicksElectronicRepair]

I hope so

amazing video keep posting!!

Thank you, I will

Hello! Thank you for sharing! What kind of flux and temps do you use to reflow the microprocessor?

[@NicksElectronicRepair]

Do not attempt this repair at home, we are professionals with almost 30,000 repairs under our belt. We have a lot of experience and while we make it look easy, there is a lot more going on than what you see on screen. Temps are not a one-size-fits-all-all. It would be a bad idea for you to use the same temps we do. Either the temps will be too low and nothing will flow for you or worse the temps might be too high and you will break the device you are trying to fix. You have to fine-tune your own machine and find the sweet spot. Use broken circuit boards that are low value or trash that you don't care about to fine-tune the temp settings. You should not be experimenting and learning how to properly rework a flip chip using this ECM. Once you are confident in your temperatures and can get good results repeatedly on a bad board, then you can start working on a good board you are trying to fix. Again I would recommend you become proficient on low-cost boards, not this ECM.

Thank you. What is the name of the tool you use to open that device? is that kind of punch

how do you know its working ?

[@NicksElectronicRepair]

I am glad you asked. We started fixing these a bit over a year ago, and at first, were only doing the driver IC chip replacement. While that did have some success, it wasn't as good a success rate as we wanted, and we would have some customers with units that would work at first but then after a week or two or after about 100 miles, it would fail again. We found out that the issue wasn't always only the driver IC chip but the processors that we reflow in the video also causing the fault. After reflowing those processors the fault would not reoccur. So now we do both repairs every time and that guarantees repair success every time for long-term results.

@@NicksElectronicRepair thanks for the info and keep up you doing a great job i like your videos

[@NicksElectronicRepair]

@@Cutycats9 So the answer I think you were looking for is no I don't have this vehicle to live test. I have some bench testing tools but the problem with either of those is that we need to run the unit for hours and hundreds of miles to really know for sure if it's fixed. Like I mentioned in my last reply some customers when we would only replace that driver IC chip would report the units working for 100 miles or more and then it would fail. So for us to full test we would have to drive around for hours with each ECM. This would require me to hire a dedicate person that would just drive around all day with each ECM and I would have to increase the repair cost significantly to accommodate for all the additional costs associated with doing that. We only charge $189 for this repair, there is a company that does more testing and repairs these, but their repair price is $600. You could call us the budget repair. We in this instance count on our customers to do that extended testing and we work with them closely if there are any issues. We provide a 1 Year warranty on this repair and do everything to try and resolve everyone's issues as best we can. However as I mentioned now that we have started performing both repairs we have not had any issues reported by any of our customers. With that said, we are always learning. If we find out new information, we will make a new updated video.

[@anttikorhonen1988]

@@NicksElectronicRepair Aren't you replacing both TPIC -chips at once?

[@NicksElectronicRepair]

@@anttikorhonen1988 So that's a really good question, and the answer is no, we aren't. The reason for this is that we realized that even though we do replace the one we do, it's actually very rarely the actual cause of the failure as we had first believed it was from our prior video before this one. The bad solder connections on the processors are actually the main failure and most common reason for these units to fail. However sometimes the processors can fail, and when that is the case they will need to be replaced. We will be making a follow-up video on this process in the near future actually.
