Jim,
Although we are not a board shop, we do have some customers who implement
SPC by inspecting developed photoresist. By placing their AOI system at
their outer layer inspection stage they can capture data based on sampling.
The data can then be used, not only to monitor the process, but also to
perform root cause analysis. One significant benefit has been to reduce
downstream bottlenecks.
