I am a design engineer and have a circuit board design with a 292 pin BGA on it. The board manufacturer is experiencing a failure rate of about 2.8% on the BGA device due to soldering problems. This is my first experience with BGA. How does the 2.

No, but answer me this? 1 What type of BGA? 2 What's the wave process, materials and temps? Are you waving the BGA or top-side flowing it? 3 If the BGA is plastic, what are you doing to prevent/remove entrapped moisture before solder processing?

| Anyone know a independent PCB inspection of BGA (X-Ray). We have several test boards that need BGA inspection. | One more source. Circuit Technology Center. Both X-ray services on Nicolet X-ray systemm and BGA rework on Air-Vac and OK Internation

| What is the best way to re-ball a BGA? Who has the best system for doing it? | Hello J.J. The easiest and best way I've found to Re-ball BGA's is from a company called Winslow Automation. They make what they call "Solderquik" BGA preforms...cou

| Any recommendations for a reballer for BGA and mBGA? Low volume, low cost appreciated! | Dave: I don't believe that reballing BGAs that go into customer products is a good idea. Check with your BGA supplier to determine their recommended maxim

| I'm not sure about limits but perhaps underfilling the BGA might easy your mind. Treat the BGA as something similar to a flip chip and dispense underfill around the part. The rigidity gained by the cured underfill may be enough to alleviate some

| | | we encounter BGA soldering issue. there is always some dry joint or unclear defects after reflow and the board can't pass electrical test, but if we resoldering it through hot air gun, every thing is ok. we use the "dog bone" surface pad ,that

I don't really no much of any problems other then, be sure that the BGA avoids moisture. If the BGA has moisture inside of it when it across the wave. Due to the heat, the moisture will evaporate and cause shorts inside the BGA. Now if someone can
