We also use PS-094 sized labels, and they don't give us any problems. I'm sure you're way ahead of me on this, but just in case, make sure that the sensor is lined up with the notches beside the labels and not the round holes on the edge of the roll

One of our customers had us building "Pb-free" assemblies with a few Sn/Pb parts on them. THEY got rolling too slowly and we were not able to bring in the required Pb-free components due to lead-time (not Pb-time) issues. When they started requesti

Amen to that!! Too many people lately trying to "get out" of rolling their GD sleeves, attaching thermocouples to the board (using their own preferred method), and running the board and profiler through the oven. I'm sick of questions like "duh, pb

We did numerous testing some years ago on matte, gloss and semigloss and found after chemical extraction of the PCB and IR analysis the only difference was the actual cure of the resist. The more plasticizers released the worse the balling If you use

As others have said, Bliss racks are not cheap, but they sure are nice. We are a small single shift shop, but we have 4 of their carts. Two for stencils and two for feeders. Even fully loaded these roll very nicely if you need to get them out of the

Thank you, all, for the honest and open discussion with just a few small sidetracks. We have had several people apply which I believe became aware of the opening thanks to this post. I can't thank you all enough for that. We are still searching but

I would say yes. I don't believe that ICT will every be replaced by boundary scan. Now on some assemblies, boundary scan is viable and certainly a better choice considering test access constraints. But ICT still will play a vital roll in the futur

We currently use Unisoft on a limited basis. It was purchased as a low cost solution to track a specific product until we can roll out a more robust tracking package. We are currently moving towards Optimal Electronics. I think their quality package

Depends on the solder paste. If it has been on the stencil for 24h there is a good chance that the paste is destroyed. You can however check if it has not dried out too much by letting the stencil printer do a few strokes and see if the paste still h
