A really nifty nest can be made by making an RTV mold of the first side of your assembly. Assuming all are identical within some small tolerance, the resulting mold holds the board very securely and distributes the loading. Cover the components with

We're in the process of purchasing a couple new reflow ovens. The ovens that we're looking at have a standard clearance of 1.00"(25.4mm), when using the Edge Rail Conveyor. We can pay a few bucks extra in increase that to 1.5" (38.1mm). I think that

If you are talking about assemblies, Class 1 is like cheap toys or something you wouldn't expect to last very long. Class 2 would be components for a television, air conditioner, automobile (except safety critical). Basically, things that you would b

Thanks Dave for the reply. I understand there is + and - to each process. We have been doing v-score for a long time and for the most part it has work for us. As PCAs become more dense and components are squeezed to use most of the PCB space, it now

Not as such. Generally, people tailor their profiles to produce glam solder connections on their boards. Search the fine SMTnet Archives for discussion on the factors affecting solder reflow recipes. What is the best way to get these PCB made to s

Is anyone having trouble with PSA (pressure sensitive adhesive) cover tape used with embossed plastic tape? I am placing 0402 components out of embossed plastic tape with PSA cover tape. The feeders gum up, the take up reels are impossible to remov

I'm the AOI operator here, and no, we do not look at DNI locations. It was considered, but overall, the extra time taken is not worth it. You could inspect some locations where components are not to be fitted, but I guess it depends on how many place

Bulk feeding components was and is a great idea, but it seems to stop there. Many P&P equipment vendors have bulk feeding capabilities and most part suppliers sell in bulk cartriges. The problem is in the use. How do you verify resitors that are sitt
