We use Selective Wave Pallets for the vast majority of our boards with great success. Many of our boards have BGA's and connectors on both sides, which for the most part then require the Selective Wave Pallet. We successfully use pallets up to 10mm t

Are the tin/lead ratios compatible betweem HASL and wave solder? Probably are, just a remote possibility. Flux application is? bubbler, sprayer? Either way, are you getting good misting, coverage on those teeny 0.5mm test points? If not, then no

Jake, The No-cleans on the market, to me, still aren't as good as OA and water wash. But they have gotten better. The type of No-Clean flux and paste to use really depends on each individual assembly, the machines used, settings, and the environme

I have been re-evaluating the way we do our visual inspection process due to its apparent ineffectiveness. We recently tested this by introducing 6 obvious defects on one assembly and gave it to one of our "esperienced" visual inspection operators. 2

Once you have the capabilities to track a board from the initial stages in kitting all the way out the door in box build the possibilities are endless. You will now have: 1. An exact count of your companies WIP. 2. The exact location of every board i
