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?
Despite the complexity, big-time damage like this can be repaired ...

Most would agree that BGA rework is nothing to chuckle about, but some of the antics performed by large BGAs when heated are definitely un-funny! We refer to the occasional tendency of larger (and thinner) BGA components to warp during rework.
The type of warping we address here can cause bridging and shorts at the outer corners of the device during replacement. This problem can require more rework at the BGA site, surely no fun at all.
It's generally understood that some minor distortion occurs in BGA components and circuit boards when ...

Microscopes have become essential tools in the rework and repair department.
While there have been many applications for other types of manually-operated vision systems, such as illuminated magnifiers and CCTV based systems, the importance of microscopes has been driven by the ever-shrinking size of electronic components, connections, and assemblies, and the spaces between adjacent components.
Microscopes used in this scenario are almost exclusively stereo zoom microscopes, which offer depth perception for the operator and the ability to zoom in for close work or to zoom out to check the work in relation to ...
