Patrick, I believe you are mistaken about this being a myth. Many component manufacturers changed more than plating to make their component withstand higher temps. Some changed mold compounds, others changed plastic types used. Many of these change

We haven't run a profile yet....probably because we're a-feared to. We can't do topside preheating here to any degree because we use an aluminum plate for aligning hundreds of top side through-hole components (pots, switches, buttons, LEDs) that te

We are getting more and more customers wanting LED boards built on White Solder Mask. Well our printers do not get as much contrast between the white mask and the plated fiducial pad, and often the camera only sees white. Other than playing with

Hi. the res/cap is mostly 805, solder paste will be led free and will only have a few fine pitch IC on each board. The boards will contain between 140 - 160 components and will run a production of 300 - 500 each day with only one or two different boa
