We picked up this old (circa late 80s) Seho 1135 machine last year for next to nothing. It needed a bit of TLC to bring it back to working order but it's 99% working now. The only problem left is that we cannot get sufficient height from the delta wa

decrease pump rpm, for penitration try tweeking pitch as well as belt speed. On the delta wave spray pitch and belt speed are related.

Hi all, it has been a bit of a delay but I've finally had a chance to do some further investigation on this. First off, we spend some time to clean the solder bath using Kester Solder Saver and scooped out a lot of crap. We then added about 5kg of

Ramp or Soak give us same Deta T (from 35 to 40).All probes are tested o.k.Should we pump in more heat upfront in order to warm up heavy loaded ICs like PLCC64 or Change blower speed? or Slow down line?

Ah, I have 3 of these ovens. Not bad ovens at all. You mentioned a PLCC 64. Is this part having the delta T problem? If so, that seems odd. Without knowing your exact set-points, you could pump in more heat up front. Change blower speeds to hig

Our new Soltec Delta 3 has this feature (they call it mainwave pushup) where you can add up to 60 rpm to the pump after the leading edge passes over the wave. Unfortunately, our old Delta Wave doesn't have this feature. Ideally we'd like to set it

I will try that next. I did speed up the wave pump motor with a larger pully(20% more speed) This was done at the time to try to increase the size of the wave because I had component leeds touching the wave pot as they passed by. Due to the wave high

Pat, Try to run a glass plate (yeah I've used these before too), keep your wave pump speed the same, and slow down your conveyor speed. You will find the actual contact between molten solder and the 0.5" grids to be LESS vs. a faster conveyor speed

Hi guys I havnt been on for a while so its nice to be back been working in europe mostly Fuji CP6 skewing rnets Marcels comment is the closest rnets are a problem as said before the main areas are 1 A good assmbley shape is a must with 30% defaul

Dross formation rates for SnCu and SAC are roughly 2.5 times the rate for SnPb (Hwang et al., 2004) Methods for reducing dross are: * Lower pot temperature * Run pump speed slower and only when soldering * Check solder contaminants to BS219, ASTM
