BGA Component Site Modification - Is It Possible?
BGA Component Site Modification - Is it Possible?
BGA rework is a topic about which volumes have been written, and in most cases the focus has been on component removal and replacement. However, equally important is the topic of BGA site modification, and the need for such modification arises often. A common type of BGA site modification is the need to add a jumper wire at a BGA site. One option is to run a jumper through a hole in the board. This method is normally used for ...

Problems with Bubbles in Conformal Coating
Ask the Experts
We operate a troubleshooting, repair, fabrication facility. The circuit cards we see are between 5 to 10 years old. They are exposed to extremes in weather and humidity. After repair/rework we apply low VOC silicone as a conformal coating. Our problem is bubbles. We've tried heating the boards to varying degrees, as well as keeping them cooler. We used various types of ...

Big Time Damaged Conductor Repair
BGA Component Site Modification - Is it Possible?
WOW! A batch of circuit boards were drilled in a spot they weren't supposed to be drilled. This can be a tough mistake to recover from when dealing with today's complex, multi-layer circuit boards. As a result, the customer found himself with a scrap heap of worthless product. What to do? The area drilled had many circuits running through it. In addition to the top and bottom surfaces, there were ...
