Simply leave the paste out at the end of the shift for the next days use. Keeping the paste refrigerated just prolongs the shelf life. Even if you are at the expiration date leaving the paste out for 36 hrs won't make any difference. Jerry

We had one product that used immersion silver plating. There were a couple of instances where we saw tarnishing, and elemental analysis confirmed the presence of sulfur. These boards did have the anti-tarnish sheets between boards, but somehow they

FYI I did try logicomm but the log files were empty. There must be something wrong with my connections from the force board to the EPC. I'll keep investigating. I also swapped the EPC to see if that makes any difference.

Try a linear, very flat ramp rate on the order of 0.5 degrees celcius per second. I know this is hard to accomplish with a five zone, but try to lower the first couple of zones (the preheat zone), and then spike to reflow aggressively during your la

gold, one of the stablest elements on the periodic table oxidising. Are you sure, and why would you want to reduce the vision fail rate on a part that is clearly shockingly poor?

On machines such as MyDatas you have the ability to mechanically center parts rather than optically centering. If your machine is capable of doing mechanical centering that would eliminate the need for the vision analysis. -Joe
