If you are using a well maintained chip shooter, you should not see more than 1%-2%, and that is on the high side. Most pick and place machines (depending on what they utilize) with laser, vision, mechanical centering will most likely reject a diffe

Just an update on my problem. I spoke to Loctite and they had very few solutions. One thing they suggested to try was to add a thirty-second soak time at 150 degrees to my reflow profile. The problem with that is ramp-soak-spike profiles doesn�t s
