Have you tried the so called push-back or re-insertion type panel? 5mm*12mm*0.3mm thick FR-4, 120-up panel is doable.

0201's on a VERY thin .010

I am looking at assembling a relatively small baord, but it is very thin and precise. It is .010" FR4, with 1oz copper two sides. ** Components are only on one side** It has some 0201's and a .4mm pitch BGA among other leadless packages. Where

i'm sure everyone has run into this at one point or another. I have a thin pcb .025 that is single up that has to be built on a pallet. does anyone have any tricks to the pallet design that will help to hold these boards down during the scree

Jig for PCB

Mark, I am having difficulty picturing exactly what you are doing, but I hope this helps. We occasionally use jigs through SMT, usually because the board is too small/thin to fit the smallest rail width. In such situations, we normally make the jig

Hello Dan, I have recently started using polyimide, but not for the standard uses. I designed a pallet for holding small, thin (about .0018" thick) RF boards that were being reflowed inside their aluminum housings. They were screwed down to prevent w

Mike: I�d hate to see you making design decisions, based solely on the discussion here, but that this would be an impetus to consult IPC-D-279, "Design Guidelines ... " and take a course on designing reliable boards. Werner Engelmaier (Engelmaier

I used to build flash memory products for M-Systems. Up to 30,000 per week. Nothing special in the process for these boards. 1mm and 0.4mm thick std. FR4 PCBs are used. Double-Sided reflow. The 0.4mm thin boards require process carriers. Panelized 24
