Edmund, following-on from Wolfy: Back in the old days, anyone who could spell "sodder" considered "bright and shiny connections" GOOD and "dull and grainy connections" BAD. Now, "dull and grainy" connections can be either GOOD or BAD, depending on

Hi Jim All the major players make soldering iron testers that will test temperature, stability, ground leakag and other parameters. WellerWA2000 Hexacon G210-G310 Edsyn MS410-MS412 Bonkote MCA700 Pace P/N8001 and others There is no particular reason

Ok, help me out here guys and gals...... I have never understood the concept of scoring on mixed technology or SMT boards. It is quite obvious to me that the potential for SMT solder joint damage through the mechanical stresses of breakout are high.

We're looking at redesigning our stencils to facilitate better (well, it's pretty much non-existant, so any improvement is a big leap) release from fine pitch apertures. Currently we have perpendicular walled laser cut apertures. We'll be having

Steve: Addressing your points: 1 FINE PITCH APERTURES Electropolishing Laser Cut Stencils: Laser cut should not requiring polishing. Geesh, how much money do you have for stencils? ;-) Oval Shaped Apertures: Pass. What do you expect to gain f

I would be afraid to have this kind of basket holding my boards. Yes, in most cases, you would not get damage if the boards were closed inside of a good, metalized (silver colored) ESD protective bag. The problem is that the boards usually have to c

JC: Seen this before, many times. We fixed our problems at the co I work for by giving a packaging specification to our purchasing dept. Took some work but the payoff was pretty big. This document includes such things as orientation,pitch,tape type

well... it might be cheaper. But I think it's a bad idea. First, your operators will hate you by the end of the day with their sore feet, not to mention lost productivity. Second, safety. Even if the plates are connected to ground through a resistor

Hany, John is right! How do I know cause I have a metal wire floor. I was faced with the same problem you are faced with now and the price was up there. I had one advantage, My floors where raised wood when we got the shop. This reduced the fati

Hi Jerry, I have a solution for you which I have done myself and shown to others which should cost you less than 100$ if you already have a microscope.This is still an operator job and an automated operation. You need two mirror squares (about 4inc
