We have a bunch of used solder paste we need removed from our facility. Who provides this type of service for a fair reasonable fee? We are in Austin, Texas and use loctite solder paste. Our supplier is Hisco, but they only provide this service for A

By used to you mean scraped from stencils and bucketed? If that's the case I'd check with the guys that recycle my dross. That's who did ours when we had volumes that justified it. Now we have so little it goes into the hazmat hamper with everything

The guys that take our dross (and pay us for it) take our barrels that contain scrapped solder paste as well. Also in the barrels are the nitrile gloves and disposable towels used in solder paste handling and cleaning. They pay us for the metal c

Check out ECS refining, they will recycle your paste and dross and cut you a check. We usually send 1 55 gal drum of dross and 1 55 gallon of waste and get a check back for ~$150. You can also contact the solder suppliers they usually have recycle

Stencil Thickness should be .005" A reduction along with cross hatching is a must for the center pad to reduce paste volume as well as to assure even paste deposit while printing on a large pad. With out the cross hatch, the squeegie will most like

Hey, I've seen a lot of AP25's with snuggers. I don't know if they all came with the pneumatics or not..but if you have the snugger reg. guage, just underneath the Z table, you should be okay. The fellas at goppm (www.goppm.com) have a lot of knowl

Good afternoon, We use both brands. Speedline�s latest printing machine generation is as good as DEK. It�s my humble opinion only. But AP 25 vacuum support system starts to fail even with fine pitch. Thanks for your input anyway. BR, Pavel
