Abstract

Electronics circuits are susceptible to production defects. Yield improvement can be obtained by in-process inspection and repair of these defects. We describe an automated laser repair system, and discuss how to optimize it to obtain best performance in terms of throughput and quality. The laser repair system can repair excess conductor defects (e.g., shorts) in printed circuit boards by an ablation process. Moreover, it includes a feedback loop by capturing images of the repaired area using a co-aligned imaging system. Here we present the automated laser system design and repair process as well as repair performance optimization.
