Histroically we have designed our pcb panel configurations around the v-score format. The QA Dept of our company is is suggesting that we revert back to tab-routing as away to avoid damage to senistive components like large package ceramic capacitors

Fancort sells a router that will singulate the boards out of the panel, and smooth the edges at the same time. I had one of these at a previous job and it worked well enough. Programming is tedious (it is done at the machine by "learning" point to

Is there are reason for going for larger (or smaller) boards when designing panels for use with a chain conveyor oven? My panels range from 0.6mm 2 layer (for touch with hatched ground) to 1.6mm 4 layer. I'm planning to go for smaller panels to reduc

| | | | | We're running into problems with board damage (broken traces, solder shorts) due to pliers and other bizarre tools being used for depanelization. I need some sort of fixture for this. A delrin plate with a slot cut to the correct depth and

I�ve seen this chatter about "fully compatible with families of alloys" in the trade journals and never really thought about it, until you posted. [You know, stay focused, don�t get distracted by what�s going on out there, and all that stuff.] Then

| Dave, | Sounds like you have material issues. Been there, done that. Tried 'em all. The best, longest lasting material I've found is called Durostone. It's made by a Roeschling, and most of the big fixture cutting houses now offer it as an option

Hey Dave, sounds like your material is delaminating at a rapid rate, I would not recommend using them through your process, delaminating material has to go some where! When composite material is made, layers of fibre glass and epoxy resin are placed
