Lead Free in 5 zones is tough sledding. Start with your manufacturers solder reflow profile and calculate your belt speed by looking at the recommended heating time for the solder paste vs. the length of your heated zones. Set your belt speed so tha

Does anybody have any information regarding an Omegameter 500 (Kenco Industries)? We’ve run 4000+ tests with this machine and all have produced a pass result without a single failure, starting to wonder if tests aren’t accurately assessing PCB cleanl

I have used one (actually 2) of these machines. The upside is you can point to the print-out and tell your customers that you do test for cleanliness, and you pass. The reality of this test is that it tests for exactly 1 type of contamination. The

Stefan, I could be wrong but I have a question about every 10th board having a defect. If a machine places 1 million components and a the board has 200 components you arrive at 5000 boards. If every 10th board has a defect, then only 500 boards have

We just placed a 56 pin QFN, 1 per board, on 10 boards and had zero defects. A good paste job, proper placement and a correct oven profile are the keys. If these are set up correctly, on larger runs your defects won't be zero but they should be le

Hi Scott, The only information that I have on the Intelliplace machine is that it is their own design unlike the other models (Casio) that they are licensed to sell. As for the other machine (Europlacer Progress 6), I have an extensive background wit

Hi All, I see more and more components like QFN or LGA with bottom-only terminations,with landpatterns getting finer all the time. I have no ppm-figures of our process, but based on a benchmark study by Agilent I'd say that 500 ppm is a decent value
