Ed, There are labs much closer to you if that's what you really want. However, we work on PWBs and assemblies daily. Give me a call offline if you're interested.

Shea >> I have several rigid flex boards which have been damaged at a contract assy. house. The boards have "bulged" in the miltilayer area of the rigid section. This section has PTH's for connectors and the "bulge" appears between the connector patterns. These boards have been processed with success in the past. Are there independent labs which could perform a failure analysis of these boards. We are located in Southern California. Thanks in advance.
