Tim- You have two separate issues 1) Stencils and 2) wave. Stencils you can purchase a ultrasonic system that will remove the paste automatically or you can use stencil wipes to remove it manually. I would refrain from using towels and IPA as it dilu

Steve, Thanks for Your replay and I agree with You. But sometimes I find it hard to always have the optimum in every aspect of our high mix/low volume electronics assembly production. We also do a lot of prototype production. In this case we had to g

Certainly, most often, the focus of pot analysis is directed at controlling impurities. Maintaining proper level of tin is important, also. When the portion of tin decreases: * Liquidous temperature increases. * Ability to wet decreases. * Solder c

Aim offers excellent soldering fluxes. That said your probably dealing with the local representative. The FIRST question to ask when evaluating any chemistry is "What is the Availability of the flux". Distributors don't necessarily stock all of a man

Hello, Could anyone provide some support concern issue with vertical fill of through hole solder. Our lead free wave soldering process is not capable to fill 100% (requirement of our customer)through hole. We made everything (DoE) - different amoun

It could be lots of things. You're not helping to narrow those alternatives. So, consider taking a sample to: * An analytical laboratory. * Teachers in the chemistry department at a local university. Kester recommends the following independent la

We agree. It sounds like your tester is possessed. If it starts vomiting pea soup, throw it away. Otherwise: * Follow Pete's suggestion by calling Alphametals [or whatever they call themselves nowadays] * Contact analytical laboratories and ask th

Hi Russ, Thanks for the reply. No this is 856, I sprayed some on boards just to try it out and noticed it dries very quickly also but if its soldered right away as would be the case in the machine, it's fine. I believe I tried some 857 and found th

Just thought of something while on the beach. We made a paste change several years ago when we installed another surface mount line. At around that same time, our maint. crew changed chain oil and about 2 months later changed when they oiled the ch

Russ, By a longer profile you mean a more even slope across the entire profile. Unfortunately I only have a 5 zone oven that is fairly short. How many heated zones are you using? Did you shrink the 0402 pad design and leave less pad exposed out a
