Hi Jacob, NC vs WS, what a story! No-clean paste means no-clean for your products but what a mess it makes in your reflow systems. If you are a contract maunufacturer of high volume production, then No-Clean is they way to go. This helps keep your co

Hi mates, actually my whole problem, is whether to : 1) To offset the heat-absorb ability of the Pallet, that artifically lowers my pcba temperature, is it advisable to artifically increase the overall, oven zone temperatures? offset by estimated +

It is possible with a few universal profiles. I did this with 3 temperature ranges and 3 speeds for each, 9 profiles total. With this setup I could run any of about 150 boards most of them in the middle 3 profiles. My goal was to reduce change over i

Thanx for the reply guys!! The problem happened on only one PBGA, the balls are eutectic and the paste volume height is at 5.96 mil min. The stencil opening has been increased to 30 mil which initially was 20 mil. You guys are right!! One probable

The question is are you talking of a reflow or wavesolder process. If your talking reflow I used to use a stepped stencil to ensure I had sufficient paste and then make a double pass with my squeegees. First pass with a 45 degree rubber squeegee to f
