OH MY GOD!! Finally it's becoming public knowledge here on the streets. YES germanium is in this material. As much as these guys and ALPHA METALS wanted to keep these things secret, anyone with a halfway competent lab would quicky find out why all of

Anybody else out there using LR-737? How is it packaged? We're using it in Semco cartridges which include a dasher and stir rod (used because the paste and flux separate relatively easily). If you are using it in this configuration, do you get a p

What's wrong with the Tin? Just wondering MDCox | | Electroless silver had promise, from Alpha, but I don't know where this ended up. Also Omikron's "white" electroless tin is proported to be a good alternative, though I've never been a big fan of

I would recommend the following chemistries: Zestron Vigon SC200... Good but very $$$$ (703) 589-1198 Vertex (sold by Petrofirm and Alpha Metals)... Won't last as long as Zestron but must less $$$ (904) 261-8286 Kyzen... Also very good (800) 84
