Where can I find laminates containing non-halogenated PCB? I'm especially interested in FR-4 and CEM-3, 1.6 mm 25um. Thanks in advance! Dr. Lennart Johansson Polymer Support

Wave soldering of Carbon Switch pads on PCB

It depends on the carbon polymer that the fabricator printed on your board. It could be: * No wave soldering * Wave soldering with a peelable mask * Wave soldering ... probably one of the latter two. Watch it. Some temporary masks can affect the

jet dispensing highly-filled polymers

SR. Here is a shot in the dark but have you try'd KNS? I know they have been working on some cool polymers...send them a note as they may have something that meets your needs. They may not have anything that can be removed but it is worth a try. pol

A common way to add traces to a fabricated board is to print polymer thick film [PTF] conductive ink. PTF suppliers are: * Du Pont de Nemours, E. I. & Co. - Research Triangle Park, NC * Ercon, Inc. - Wareham, MA * Dow Corning� * Asahi Chemical Res

Plastic fingers for wave solder machines

Electronics Forum | Mon Jan 31 10:21:27 EST 2000 | boca raton

I've seen some plastic fingers advertised for wave solder machines. Anyone used 'em? They are 'glass-reinforeced polymer resin', they are supposed to stand the heat, can be mixed with titanium fingers on the machine, and cheaper! (near and dear to
