Hi there. We have had an out of control reflow oven that has allowed its temperature to fluctuate by up to +/- 20 deg C from set point in very short periods of time. We found the root cause of the problem and fixed it, but by then we had already run

What you need to remember is Fuji didn't make a name for itself by building this XP platform. They're strengths are/were in their chipshooters. Don't just assume that because it's Fuji it won't have reliabilty issues. I'm not sold on this platform ye

Thanks for the reply Rob, This we already do. The machine will pick from the most efficient available feeder (assuming multiples of the same part number)...so when you remove the primary it will seemlessly move to the next available. When you re-in

Hey Greg, As you already pointed out yourself: unless you can do away with covertape pickup-spools (or can figure out a way to empty them without loosing tension on the covertape) your feeders will not be suitable for several consecutive splices. S

Sure you can use it it with leaded HASL. Recognize that ... * Your Sn42/Bi58 will no linger be Sn42/Bi58 * Your leaded HASL will no longer be the same leaded HASL that walked in the door to your plant * Lead from HASL coatings can diffuse through the

Yes, we can't use pure Pb PROCESS. And as I say we will not use it anyway, as we have lead-free BGA's, LGAs, component with Solder Charged Terminations... It's became almost normal practice to solder it with leaded solder pastes. In this case peak re

First, it depends on the alloy composition of the solder. As you might know, eutectic Sn/Pb solder has the lowest melting point among available conventional solder systems. (except those based on Sn-In and Sn-Bi systems.) For example, 63Sn/37Pb - 183
