Hi, when they did the reflow with the south bridge chipset they took a heat gun and went arround the chip in circles. This is what I did with the broken apple motherboard. I covered the board in tinfoil and cut out the squares arround the gpu, cpu an

Just so that we both on the same page: * When you "reflow the chips on the broken board," what do you actually do? How do you do it? What kind of controls do you use? * When someone "did a reflow on the south bridge chipset," what do they do?

Phil is correct in his description of proper rework technique. Possible explanations of the reason for popping of your BGA are: * Thermal cycling of components cause them to flex on a different point in the cycle that the board possibly resulting in

Reflowing a BGA can be a reliable and long term fix, but it has to be done correclty, and using a heat gun and going in circles around the part is definitly not the right way to do it. To do it correctly you would flux under the bga, use a rework st

Hi I did a reflow on an HP laptop a while back- it was a DV6000 series. The original problem was the internet stopped working- turns out the south bridge chipset was causing the issue (its a very common issue I found out after searching online). Some

Hello John, The biggest stumbling block is going to be taking these responses and applying them to your assembly process much the same as trying to make other manufacturers' defect levels apply to your process. Ultimately, the overall quality of yo

Hey folks, I have a few designs that I'm using a MEMS I2S microphone on, and the PCBs have to be cleaned as I use water based SAC305 - but the supplier states to NOT ultrasonically clean their microphones. Has anyone here been through the process of
