Production of 50000, is this per year, per month, per week, what? As for your budget of 80000 Euro, that is no much to go on. For a basic SMT line, you need at least 1 paste printer, 1 placement machine and 1 reflow oven. If you have any through-hole

Very late but here's my 2 cents. Will require a custom fixture for every flex or semi-rigid flex. Depending on panel thickness; use 2 tooling hole to fixture on one axis, other tooling holes will have pullers to ensure proper placement. Even with the

Search the fine SMTnet Archives for previous discussion. This technique has been called 'pin-in-paste,' 'paste-in-hole,' 'intrusive reflow,' 'alternative assembly and reflow technology' and who can remember all the other consultant buzz-words. Look a

We agree with Huss. Your clearance 8 to 11 thou between lead and hole make ion difficult. And that assumes the 0.027 to 0.030" hole size is the finished, not drilled size. It just gets worse if this hole size doesn't consider plating.

0.001969" You say that 0.008" of "slop" is un-doable; hence, the reasons for our failures. Any basis for that statement? Are rated accuracies from placement equipment manufacturers typically "exgaggerated?" 2. On PCB Fab side of things, what is

John, having worked at a major U.S. telecommunications co. I can tell you we were placing through hole connectors in SMT. Using MPM printers 3000 2000 AP36 AP24. We opened the apertures on the stencil 25% over lead diameter to allow more paste(it wou

Change your board to bigger holes.
