The "correct" answer is: Use the tests and methods that you used to qualify your solder paste in the first place. That sounds good but might not be all that practical for practicing assembly-types. Here's something that's not as good, but will give

We've actually bought a second FX-D, which is intended to mainly handle smaller, higher-volume boards. That will still serve to improve throughput. But at the same time, we're also adding another pick'n'place machine which has a rated speed that's 2

When I and some friends worked on this project we were aiming for an hour turnaround time. But as the years of development went on we upped the board specification considerably. Also the world changed under out feet as we could get commercial protot

A couple of things that have helped me with solder ball issues at wave in the past: 1. Flux. Insure good flux coverage on the bottom of the board. 2. Preheat. Insure that the board is sufficiently preheated for the wave operation. Since you're

Sr. Tech, you are right in that there is no verification of the profile. We are a Class 3 high mix OEM. We have visual inspection after SMT. We have not seen problems with wetting, grainy solder, cold solder, charred boards, etc. that would indicate

I have a customer who is rather inexperienced, and asking us for a solution for them. They have a circuit board that's roughly two inches long by 1/2" wide or so, with component placements on one end of the board. The other end has a trace that I s

I’ve been tasked with acquiring both pricing and specification information on potential X-Ray units. If possible I would like to gather information on both low-end and high-end units. Here is some information on our facility. I have been to facili

Sorry if I was not clear. We have a Flex Circuit Board that is ENIG Finished. There are two connectors that are SMTd to either side of the Flex to connect to other PCBs within the system. Then, we have conductive rubber contacts that are press fit on
