Hello everyone, Talking to my boss today I was able to determine what we're really looking for in terms of reflow soldering. The company is not looking to do a volume run; we're trying to solder chips for prototype boards, which are currently done w

I replied on the weekend but now I'm at work and I can clearly see what you mean. The Part Name is the footprint for the part and it is common for a lot of feeders which is obviously wrong. I think I need to make new part numbers for the footprints s

Hi All, I've been working with this machine for several weeks. I read the manual and I'm using the autoprogramming (ATT) with centroid data. I have a question regarding the teaching of the parts. Let's say I have 10 capacitors on the PCB that are th

Hi Bill, I agree with not cleaning the no-clean. If you're looking for a cleaner because one of your customers is requiring no residue be left on the PCB's, I'd investigate switching to a Water Soluable Process for those specific assemblies. (You'll

We use both the black conductive and blue static dissipative ESD totes in the production of Class 3 military electronic assemblies. In some cases we use ESD bags, but most board assemblies are placed directly in an ESD tote with a lid. The totes cont

I was wondering if anyone else out there using the Vectorguard system by DEK has had problems with leaking air bladders. We started using a 29 x 29 frame about a year ago, and already, we've needed to send the frame back 3 times for repair due to int

We've been having issues with our current process of oven profiles. We use a high temp adhesive to bond the thermal couples to the desired components. The issue of them letting go or releasing during reflow temps are hit or miss. Majority of our buis
