Bob, The responses to my question kind of supported my first instinct to avoid waving TSOPs. Plan B may be to find a compliant pin connector and convection reflow both sides. Any comments? Greg : The first thing is all the TSOP suppliers like Inte

Hey guys, I ran a couple of profile in our wave solder machine using wave optimizer and this is what i got: Parallelism = 0.0 Immersion Depth = 2.1mm to 2.4mm with varying immersion time from 1.1 sec to 3.1 secs. Contact Length = between 5.0 to 6.0

The Electra is Electrovert's top-of-the-line wave solder machine. Just about the best you could get. Conveyor concerns should focus on the condition of the extruded rails. A machine that new should not have a problem, buy worth a look see. Find out i

When you say all over the board, please give more detail. Where are they located? [All over wave soldered portion, laminate only, solder mask only, solder only, specific components only, etc] When you say white residue, what color are they really?

The parameters which effect the problem you are having are flux and contact time try first increasing the flux you are applying. Next reduce the contact time in the wave by adjusting the back flow plate. If the problem is a jig design check out the j

if your solder wave machine has a removable solder pot, consider getting a second solder pot. So you will start with a brand new empty solder pot. Keep the current one with your current solder as a backup.

| Surprisingly enough, ever since the addition of an omega wave, we solder those often-troublesome SOT23's just fine and dandy.. anyways, long-term, well be getting a universal GDM which uses positive displacement pumps..currently we're using fuji g

80-90% of an average SM component is non wetable (pushing away solder). So if you would use a single smooth lambda wave (massive amount of molten metal) the negative force of the non-wetable part of the component would be so high that the solder wou

I have 2 contract manufacturers who have recently switched to immersion tin and both are experiencing problems. One supplier is having problems reflowing the solder in the oven, while the other is having insufficient hole fill at wave solder. Both ha

Hi All We have run the Hast Burn-in-Board into 2 soldering Process,first-Reflow and second-Wave. After wave soldering, there are many insufficient solder in the via holes.The via holes are wide as 15mil. Then, as customer's request, we have to cover
