| Hi, | We are having problem with yield loss due to electrical fail. Further investigation shows that the failure is due to solder bridging under BGA. Has been there any study or experience on how this could occur and what we can do to prevent it.

Simple x-ray inspection works well have a word with those nice people at Nicolet or Glenbrook. One of them was featured on my x-ray training video for BGA. A procedure for inspection criteria is on my web site if it is of use. | | How do I mechanical
