Solder in wave soldering: Which one is the best?

Electronics Forum | Mon Feb 28 10:54:08 EST 2005 | lyrtech

I have another question: Does the slope of the conveyor is an important parameter in the solder joint quality? What is the standard in degree? Does that parameter can resolve my problem of partial fulling hole (between 50 and 75%)?

Touch-up and Inspection Process

Hi Greg, Is anyone logging the errors at QC/touch up stage so they can feed them straight back to SMT and fix them? (i.e. skipped components, poor paste coverage etc) Obviously the faster you spot an error the cheaper it will be for you. Cheers,

We have a couple of presses we use for cutting adhesive backers & depanelising flex's etc. You can usually get away with steel rule dies which cost a couple of hundred dollars instead of hard tooling.

Solder bath eruptions

Electronics Forum | Mon Mar 07 08:03:14 EST 2005 | jonathanpaul

Have any of you ever experienced minor eruptions in your solder bath while it is heating up? Our solder bath splashes solder while it's heating. Once the bath is molten, it no longer does. Can anyone suggest a cause?

Rule 1: Clean it as soon as you see it! Don't let it dry. It's harder to clean up and can be easily injested when in a dry powder form. Rule 2: See rule 1

Reflow Profile ENIG Vs. Immersion Ag

Electronics Forum | Thu Mar 17 12:51:39 EST 2005 | Slow Ride

How much more? A couple degrees? That would be normal from one board to another, depending if the t-coupls are in the exact same spot etc. What type oven? IR ovens can be affected by colors.
