Abstract

Repair of open circuit lines on boards often requires only a small droplet of plating solution on the area to be repaired. However, if only a small droplet is applied to a localized area, it becomes very difficult if not impossible to direct the laser through the droplet to cause the local heating required for thermally driven exchange plating.
