| My printer evaluation has come down to the Fuji GP-6 or the Dek 265LT. I'm looking for experienced opinions on both of these options, we're currently running an older vintage Dek 265 printer that gives us constant electronic system problems. The v

I'd recommend not using them, personally :) The long term reliability of the SMT joint is suspect, IMHO. I had them for an in-house manufactured bed-of-nails test fixture for testing somewhere north of 5000 units....after the first 100, we were rep

Hello Dave, Before I get into waste management, I must first stress the importance of checking with your local regulating agencies. Every area can be and usually is different. California regulations differ from Ohio and Ohio�s are different than Mu

We find that the raw BGA's pad sheared surface has the SnPb solder at various Z heights whereas the assembled BGAs pad leave a smooth layer of SnPb along the pad. Like to understand the cause for the difference. Who could guess? Solder joint streng
