I use Kyzen's Aquanox SSA cleaner in a heated parts cleaning tub to clean anything with flux condensate on it. When heated to 120F, the stuff melts away like ice under hot water. When the cleaning solution is loaded, I send it in an evaporator. The s

Hi Dave Interesting points. If I understand you correctly 1. about 2% of part numbers have a moisture problem 2. Packaging frequently comes in with expired dates on them. This seems hard to believe you would accept them. 3. To really solve the

I would like to understand what different options people are using to place low volume / odd form parts. I am very familiar with the tweezers / vacuum pen method however this can be less than desirable. I am looking into a manual pick and place to
