Yea, I'm still here.....sigh. Got bridging problems. These assemblies are SMT topside, then go thru wave for thru-hole components on topside. These assemblies have many, many, many vias VERY close together. We have a problem with solder from the wa

Maybe more baking time is needed. Topside board temp too low. Moisture trapped in board. Top of through hole capped by component and trapping flux. http://www.speedlinetech.com/electrovert/electrovert-troubleshooting/index.htm

Using no-clean flux will make the boards very difficult to clean. If you can switch to water soluble flux, your life will be much easier. The "icicles" lead me to think that the board isn't getting hot enough in the pre-heat cycle, and/or there isn

Your point about thermosets getting soft in the preheater of the wave is well taken. But an adhesive that is used past its expiry or other up-front lack of process control represent 99 & 44/100 percent of the reason for �glued parts falling off in

For as much as you can minimize bridging in these condition by changing board orientation, the only way to eliminate them may be to add debridging airknife tech to your system, or purchase a system that is fitted with this technology. We have been t

interesting Bill, will keep an eye out. Was not necessarily saying anything about Chinese product, just the engineering, I have seen a few Chinese "Vitronics" ovens and yes they seemed to be put together very well, I was only mentioning how it/the

That's basically it. In a wonderful world, the oxides flow on top of the flux during heating through reflow. Obviously when compared to reflow soldering, you create much more dross with your wave by: * Pumping a large volume of very hot solder to h

Hi Joseph, It's difficult to troubleshoot if the defect is unknown, but I agree with Chris The majority of components are already lead-free and only 17% of the worldwide electronics industry switched to lead-free wave and/or paste so the majority o
