i have an issue with solder bath temperature. there is a big difference in temperature of alloy in the middle of the bath and at the ends(about 35C). i took down heating elements for inspection and they look fine. its just that most of the heat is cr

What type of solder are you using, Lead or Lead-Free? What is the melting point of it? What temperature are you setting your solder bath to? Possible solutions: 1) Give your solder bath a little more time to even out the temperature across the en

During installation, the tech should calibrate the machine. Have them demonstrate the pick/place capabilities while they're in house. Most companies that I've dealt with would like you to have an example product to run while they're in house, as we

Ok, that's small - I think you may need a special semi-conductor printer for this - positional accuracy on a "normal" SMT printer is no more than 20 micrometres from memory. In my semiconductror fab days we were printing with a positional accuracy

Joshua, 100um is 4mil aperture. You should ask several stencil houses about the possibility to print that small amount of paste(type 6 paste is available now with very small solder spheres 5-15um diameter). Even applying small amount(thin layer of f

Solder flux and solder paste deposition is a standard step during the chip attach and sphere attach portions of BGA and CSP assembly. A technique called ultra-violet fluorescence intensity mapping (UV FIM) has been introduced that allows flux measure

You should have no problem. We use a very dated Asymtek machine (Automove 303) retrofitted for dispensing, air over syringe. It took time and some tinkering with. But all things considered, we're able to achieve remarkable results. I would recommend

We have been using Vitronics for over 20 years with very few problems. I imagine Heller is just as good, I would rather you talk to your Solder provider Rep to find out about any add-ons you need for your specific processes. Along with that info and

@ Westshoredesign: Go take the top covers off your XPM's. Tell me if you see flux residue on the blower motors and the surrounding area. If you see this, grab ahold of the blower motor and rock it back and fourth. It is moves, the seals are melted o
