We are looking for machine that can do the following: bonding of 0.5x0.5x0.8mm mm cramic part. - detect target surface position 1.5x0.8mm - dispance a drop of 0.8mm of epoxy adhesive on trget surface with position accuracy of +/-0.04mm. - pick the 0.

Hi, all. There is one 0.8mmX0.8mm QFN on almost of our PWBAs. But the quality report showed that we got bad solder quality for this component. My question is which elements are the root cause for this situation frequently? Thanks.

We are designing board which have to plug in M.2 connector and thickness is limited to 0.8 mm The board is very complex with many BGAs and DDR3 memory chips and we will need 6 layers for routing. The problem is that we will need signals with 50, 90

When faced with a problem like this I sometimes look at competitive products and see what they have done. You may be able to get away with 4 layers if you have the space, however if it is jammed up that will not be an option. I presume that the total

Any aperture/stencil thickness suggestion to provide a rigid solder joint for 0.8mm pitch PBGA with 0.4mm ball diameter. The pad is based on IPC7095 and it is 0.3mm. Thank!

I would go with wire thickness + 0.4 to 0.8 mm for pad width, and pre-tinned lenght + 0.5mm what seems to me like problem is that it can easily roll off the pads in reflow oven

What is the best aperture opening for micrBGA with 0.8 mm ball pitch and 16 mils ball diameter?The pad size on the PCB is 12 mils.
