When gold edge contacts can become worn, damaged or contaminated by solder, they must be either repaired and restored, or replaced.
Both procedures result in a high conformance level repair that is reliable and long lasting.
Replating is a reliable, yet complicated, process requiring a considerable amount of setup, special chemistry that is hazardous and, in general, a high level of operator skill and training. Gold re-plating is the best choice when a significant volume of re-plating is needed to justify the setup ...

We've all heard of via in pad, blind vias, even buried vias, but have you ever experienced the "via to nowhere" phenomena? Well, here's how it goes.
We received a distress call from a customer that found they were missing ten vias on their now populated circuit boards. The vias were supposed to connect from surface circuitry, to an internal ground layer. Every other part of the design was intact, except for the missing plated via connections.
What is the best approach when trying to create a through board connection ...

It's not unusual for circuit boards that have been fabricated to require additional milling to reduce thickness on certain areas of the circuit board. This milling is normally completed by the circuit board fabricator prior to board assembly.
Usually, this milling is done to allow the installation of face-plates, bezels, or the insertion of the circuit board into a card slot without restriction. Occasionally, the milling operation is either missed, or not milled to the desired thickness. We have often been asked to perform the milling operation on assembled circuit boards.
