This is somewhat Mac related, but I think it's more of a chip issue (esp on factory-assembled boards), so I figured I'd post here. Basically, I'm having repeated failures of an ATI 4850 graphics card ...

[Colin] uses some spare boards to lock the target board down to his bench and then uses a custom stencil and solder paste to prep the board. Once he has the solder paste on, he places the components ...

So, you’re trying to get a handle on BGA flip chip tech? It’s one of those things that sounds complicated, but once you break ...

BGA soldering is very reliable if done using the correct procedure, so we introduce GA Soldering on PCB board, BGA Inspection and BGA Rework. According to different packaging materials, BGA components ...

In our previous article on Ball Grid Arrays (BGAs), we explored how to design circuit boards and how to route the signals coming out of a BGA package. But designing a board is one thing – soldering ...

Conversely,experienced embedded designers know to mask or tent BGA vias at thedesign and layout level. Even when this step is omitted, adesign-for-manufacture (DFM) check mapped out at the planning ...
