| What would be a good metric for process control of a stencil printer? (fully automatic, vision equipped, stendil printer). | I'm doing some more DEK 265 GSX's with everything imaginable hung on them. Have done Lt's and the MPM2000. This makes mach

I've done it 3 different ways in my career (3 different places): 1.) Process Engineering was responsible for solder paste inventory (as well as all other process materials). That was a bad situation due to the blame factor. 2.) TOOL-CRIB control

What is the maximum PCB shelf life for double side PCBs after first reflow? I mean, after assembly bottom side, how long can I keep the PCB without solder paste waiting for the second reflow? (Considering exposure on production environment conditions

K: Do you shelf life control rolled solder because of the flux core?

Most paste manufacturers talk about a 12 month shelf life for paste. They give the user half of that time. The remainder is used-up in processing and distribution. We'd give it a shot. You paste supplier should be able to give you a much clearer

From Kester's web site: "Flux cored solder wire has a limited shelf life determined by the alloy used in the wire. For alloys containing more than 70% lead, the shelf life is two years from date of manufacture. Other alloys have a shelf life of thr

Many solder wire suppliers put a on rolls of solder wire either a: * "Date of manufacture" stamp and then specify a shelf life in their product documentation ... OR * "Date of expiration." J-STD-005, 6.2, 6.3, and Table 4, where it states "If the st

Curiously... Shelf-life of the plating alternatives has been mentioned several times as a potential issue in these discussions. Tell me is there a market for a simple plastic packaging which could extend shelf life (and hence solderability) of these
