From our experience with our gel fluxes the depth of the flux cavity can be 30% ~ 70% of the ball diameter. You'll probably need to do some tests to find the optimum for your process. If you have really fast movement on pick and placement machine the

We recently purchased a used Sayaka De-Panelizer Router. There is a manual included from Japan, however we cannot figure out how to get to the programming screens. The manual states to select the Mode button several times until the screens come up bu

Shannon, We have been using VP for all of our lead free production since 2007. Here are the items I can think of off the top of my head. Pro's - small footprint, minimal profiling needed once machine is understood, oxygen free soldering process, s

They all are inlineish They just carry the board to the vapor chamber. in a reflow system all the boards in the oven from beginning to end are in state of process, which gives you more speed. If the board has a long cycle time VP is not a problem. If

Certainly the bridge is ugly, but the voiding is nothing that you should be bragging about either. Pretty ugly work. BRIDGING: If all of your shorts appear in the vacinity of the heat sink, consider reducing the amount of paste that you apply there.

Thanks davef Bridging:- There is no heat sink on the BGA, the heat sink will be fix after relow. I do believe paste had something to do with it, but currently this defect didn't appear so oftenly, so we think that the main root cause is not from the
