I never could type on a laptop. Keyboard's just too small and to many typos. I'm just curious about more of this CAF stuff. I can understand a minimal amount of hydrolization of salts creating deleterious effects in plated hole walls, etc. I just don't get how epoxy resin systems, at about .2% hygroscopisity, get that done. That's really a small percentage. Polyimide, at about .5%, seems more likely a candidate. Aslo, I could not imagine drilling holes, however large they may be and still provide some annular ring, on 10.5 mil centers. Who's doing that? What's behind this but for you industry leaders seeing down the road 25 years or just needing something to do in this crappy economy? Poor Howie at Lucent where very little is going on. I'll bet he is wishing he was in the real world as well. I also don't understand any product lasting 25 years in this technological climate. If so, I always warn clients not to use HASL - but especially OSP's. I also discuss carefully, when needed, what you really need. I can see some MCM's affected but wouldn't/shouldn't these designs be ASICS instead? You folks aren't over my head in any way but what possible use is the CAF stuff but for stuffing a contract with more stuff not needed. I still need master and assembly drawing notes for "norman" PCB's. Don't you?
