By Hot Air Knife I assume (leave it alone Dave F.) that you mean a debridging knife located at the exit end of a wave solder machine. Russ is right, they are not a good substitute for a good process, but once the process (w/o HAK) is developed, it

Stencil printers, what's really out there?

Electronics Forum | Tue Feb 22 13:58:15 EST 2000 | Steve Thomas

I'm looking at stencil printers, particularly those that can produce good repeatable prints on finepitch boards with minimal setup and training. I would love to find a printer that does auto x-y-theta alignment (would like a system that aligns sten

Effective Alternatives To Stencil Cleaning

I have a knack for asking those "set-up" questions of sales types during their presentations. It's so bad, I don't even have to pay for lunch to attend SMTA meetings. The "presenter" pays for Dave. YES!!! I've read the Richard S. Clouthier "SMT S

Line tech in need of help

Wait, wait, wait ... I'm not completely sure what a line tech does, but I was his / her boss, I would not be happy if the first thing my new line tech [or any other employee] did was to suggest that I go out and spend BIG $$$ [especially before he /

Adhesive Application by Stencil

Electronics Forum | Thu Mar 22 16:52:10 EST 2001 | kaopsahl

Yes, there are adhesives designed just for stencil application. Usually plastic squeegee blades are recommended for best printing results. Plastic stencils are also available for this application. Both Alpha Metals and Loctite have articles on this s

Stencil Cleaning

Proper setup and cleaning of stencil helps ensure repeatable printing performance. Cleaning processes need to be compatible with materials used in the manufacturing of stencils and solder paste. IPC 7525 should also help you out. We here would Inspe

These parts are flat chip resistor arrays that have 4 end terminations on each side. It looks liek an IC but is typically in an 0805 and 1206 package type with convex terminations. .031" pitch from termination to termination and .011" spacing between

AOI vs. XRay

Electronics Forum | Tue May 08 11:27:49 EDT 2001 | Eyal Duzy

I will review some of the advantages/disadvantages of AOI vs. X-Ray one by one according to the main differences that you may find between them. * AOI uses optics that can "see" only visible elements. X-Ray can "see" hidden elements. There is a ve

Life of a Solder Stencil

IPC-7525 "Stencil Design Guidelines" �9 END OF LIFE, states "Stencils should be inspected periodically for damage that would conribute to decreased printing performance. Refer to Section 7 for inspection guidelines." Or words to that effect. Now b
