We autoclave our medical PC boards (Sorry Bad Joke). With the Steam process I am concerned that the water (Solution) is not Clean. So I am curious to the process of steam cleaning: Is It Presure Steam? is the Water DI, ION free, street water...? you

Of course there are solvents which are less harmful to the environment than others. The operative phrase is �less harmful�. As a rule, water-based chemistries are �greener� than solvents. There are some solvent blends designed for aqueous-based eq

I am curious on some opinions on cleaning of boards. We have a board wash but after the wash we still need to stem them for better cleaniness. The timed steaming is prox. 2 mins a side and by the way this is a medical board. So if you got and suggest

Thinner: Flux thinner, NOT paint thinner We kept a spare stone in thinner in inventory. We cut PVC pipe to size, cap in one end, screw thread on the other, stone inside, filled with flux thinner and covered with a screw cap. I don't remember who we

...ahh....memory lane. 10 years ago I worked on a project for a customer who needed a low cost, high volume board for RFID tags for cows (yes, moo). These boards were 0.50 inch in diameter, 50 per panel, double sided SMT punch style fabs. 300,000 b
