Hi everyone. I am now faced with a problem on soldering PBGA. At first, I ran the board (FR4, 7" X 10" with 12 layer) at Peak Temp: 205 C and 54 seconds above 183 C. After reflow, I found several cold solder joints and one ball without second collaps

I am wondering if anyone has had issues with their Heller oven rails warping. It appears that our 1800EXL and 1900W oven rails sag after time. They eventually contact the safety mesh and then create hestitation of the chain, thus creating defects.

Hi there. I am currently kinda in the same spot as the author of the thread. My choice is between Rehm VXC and Heller 1809. I am a little concerned about Heller advertising their 25cm/10 in zones. I am used to large ovens designed for high throughput

Hello Don, We dont heat cure any of our assemblies. We coat relitively few boards and just let them cure at room temp. Perhaps we should start heat curing. In fact, we have an old, fully functional, heller 1500 just sitting in storage. Hmmm. . .
