Hi. I agree that the Soltec has weak, low-wattage preheaters, and also, the Soltec's fluxer is flippin' weak too. It doesn't do a good jab of atomizing the flux and getting good, huh-huh, penetration on the holes. I cranked up my Soltec's pressu

Flux: Getting enough- is the spray fluxer getting good through-hole penetration. Try cranking it up. Soltec spray fluxers are not really as good as Ultrasonic Systems or Sonotek ultrasonics or the new ServoJET, but should do the job. Also, try anothe

From my past experience, you can usually get away with OUT the chip wave if your SMD's are no smaller that 0805, and more importantly, there are no SOT23's. A nice, clean, inerted laminar wave (with a little smart or omega help) will solder your S

Hi, We have spent the day trying to profile our Vitroncis Soltec Delta C wave with the new SN100C solder, but having problems with the heavy pins on some BNC connectors we are using. We have Interflux no residue flux, and we are using palettes, whi

Hi, Your right guys, and we turned off the chip wave, and most of the problem went away. It looks much better, and we are getting a slight bridging on a USB connector at the front edge of the PCB and a little adhesion, but not any where as much as w

Hi, I would also be interested in this thread, but our problem has a different twist to it. We have good results from our reflow with Koki no clean paste, however when we pass the boards through the wave solder machine, the flux in that leaves a fog

Hi Grant, You definitely have a pre-heat problem and not a flux problem. Pallets together with the BNC connectors put a large thermal demand on your pre-heating. 3 zones would be a good investment even with leaded solder due to the high thermal dema

In 1995 we bought 4 Vitronics U520 reflow ovens with top heat only. We ran these ovens until 2003 for both curing and lead reflow with no problems. In 1998 we bought 1 U520 top and bottom heat and one U820 top and bottom heat and once again we had

Hi, We have the Soltec Delta C. It works well, and is very stable. I think the software is a bit simplistic, but it keeps the wave stable, so that's the main thing. It's the timer on the software that I find annoying. It has a warm up time, and yo

Hi, Thanks for all the help guys, and we did a bunch of things to get it working. We raised the pump speed, and also went to a water based flux, which helped a lot. We also reduce pre heat as we were burning off the flux. It's doing really nice jo
