GS, What should be the temperature we should get down to? Is it room temperature? Then it could be quite a long time. Eutectic solders cool down below 183C and may be cooling to 100C should do good? What do you think?

Who remembers the Heller 942C reflow oven? We have one, but I cannot locate the manual or computer program, and the ones that ran it have now retired. Any suggestions would be appreciated! Thanks, Jim

Background on activation energy for diffusion can be found: * Materials textbooks * College lectures posted on the web. Use 'google' or someother search tool. As a guideline, the higher the activation energy, the harder is is for diffusion to occur

I have a Jewel box and have found it to be a very simple system to operate. We have had several turn overs with operators and the new people master the machine in a very short period of time. You are right. This is an excellent machine.

Hi all, does anyone of you use step stencils for paste application? Did anyone experienced troubles with those kind of stencils? thanks for answer sly

We agree with Russ. * Haven't used them in 10+ years. * Size of keepout for the stepped apertures needs to be large. * Manipulating aperure size to manage paste volume for specific components is not difficult.

Hi russ, thanks for answers, I thought that playing with apertures was the solution if paste is able to lose from the screen with fine pitches. But I'll take in consideration all of your remarks for the next designs to be develloped.
