A good resource for implementing a BGA assembly process is: IPC-7095C Design and Assembly Process Implementation for BGAs Lots of valuable information in that publication.

A good resource for implementing/evaluating a BGA process is IPC-7095C - "Design and Assembly Process Implementation for BGAs". I get no monetary or other compensation for promoting that standard but it is fun to mention that a board assembled by my

Is there a standard that tells you how many times you can replace a PBGA without reliability issues? I've read IPC-7095 (many times) and have not found a recommendation for this. We have Class 3 products.My thoughts are 2 times max. We place PBGAs

"LGA" [land grid array] is a pretty broad topic. Search the fine SMTnet Archives for background on: * BGA * uBGA * Flip chip * etc Consider: * Area Array Packaging Handbook: Manufacturing and Assembly; Ken Gilleo; McGraw-Hill Professional; 1st edit

Also look at IPC 7095 which is all abotu BGA processes including rework. the profile will be 100% based on your board - how many layers, how many are ground & signal, how many of those are the BGA connected to directly or indirectly, the component we
