A few other data points to consider. My experience working with Dymax 984LVF material was that its UV cure must be initiated immediately after coating, otherwise is surface will remain tacky forever, something like a post-it note tackiness, which wi

Hi Carlton, I'm sure you are a good person who wishes to explore something new, each time. Your attitude is absolutely human, but is not always appreciated by the professional world. I read your resume and would like to advise the following: 1. Since

Yes, We've already experienced this same problem. 1) What kind of flux are you using? No Clean? Rosin? OA? 2) If it's OA, What kind of water wash do you do? Do you use DI water? How Hot? Who's machine? What are the pressures? 3) Have you performed a

We are getting what looks like cold solder joints on one of our boards. The boards have an aluminum substrate, and use OSP plating. The solder is lead free - 96.5 Sn, 3.0 Ag, .5 Cu. The flux is no clean. When we first had the problem, my solder profi

Hello, I have searched endlessly to get a good description of how these are manufactured and exactly how they are supposed to work. I have yet to find anything comprehensive. Our CEM ships our PCBs to us in plain cardboard boxes with Conductive Corr

Unfortunately, I don't see any image. If your part will survive 300C then even convection reflow should work. The use of paste and reflow ovens are for when you move to production quantities. It sounds like you could hand solder your prototypes (proo

I have very little knowledge of pick and place machines or assembly, and was hoping someone could give me some advice of where to start looking. I do learn quickly so I am not afraid of challenges or learning through mistakes. I need to produce abou

Assuming you want to run 8 hours a day and 5 days a week, you need a sustained throughput of 2.5k components per hour. With fine pitch, futzing around, setup, etc you should really look for machines rated in the 4k to 5k per hour range. That's not sc

I have a little problem. We are assembly subcontractor and we purchase most parts ourselves. Currently we have all BOM/Partlists in an Excel format. We get a few RFQ each month, prices come from well known original sources, Mouser, Digikey etc. and
