I'm hoping to hear what others are doing regarding "recycling" paste. By recycling paste, I'm referring to an operator taking the paste left over on a stencil after a work order is done and putting it either back into the jar it came from originall

Heller and BTU both sell well respected ovens for considerably less $$ than a Vitronics. If you really like ITWAE brands, when I was last looking Electrovert was somewhat more affordable. Your region may also have other reliable Chinese brands, I thi

One trick that I use when I need additional paste for a larger part like a connector with thick leads is KAPTON. I'll put a thin strip of Kapton on the board side of the stencil along the apertures where I need more paste. Kapton is about 2.5mils th

We relocated an operator from AOI. There were a few issues, but one that really caught the attention of Engineering was that an IC with 4 legs on one side and 3 legs on the other was placed 180° out. The machine flagged it. The operator looked at t

Our dek APi X started having alignment problems suddenly and we aren't sure why. The board is close, but mainly shifted toward the rear of the machine so we are not able to print with it. I performed reference alignment which works properly. I then
