I am looking to discuss 0402 issues, specifically tombstoning/unsoldered. Any recommendations on pad size/spacing, stencil design etc would be helpful. Placement and reflow profile look good.

Mike -- Thanks for the information. It is very helpful. Is there any information available that shows what flux most companies are using? What fluxes are most companies that are producing Space, MIL-Spec, or other high-reliability assemblies usin

We are manufacturing a PCB that uses an integrated circuit that has a leg spacing of 10 mils, other components on the PCB are 1206's and 0805's. Is it possible to make the stencil apertures 10 mils apart or is there another way of making the stencil.

Depending on the designers pad size, I generally go for 0.010" aperture with 0.010" spacing - stencil thickness 0.005". This combo with metal squeegees and the "usual suspects" of printer set up and placement details should you you hassle free.

Also, what about the gap spacing on your machine between the top of the second wave baffle to the bottom of the finger? Ours is at 5.7mm. Thx.

We currently use process carriers to run our products. We do not have chillers at the end of the reflow ovens (no space) so you can imagine how hot the carriers come through. Are there any cooling racks out on the market that I can look into to pla

A fairly dense brickwall would have 0.020" (0.05mm) spacing

Does anyone know where I could obtain a copy of a report on BGAs in space which was done by the Jet Propulsion Laboratory in the USA? I am interested in any other info anyone may have on this subject. Many thanks Jenny

you also may find that varying the width/spacing of your breakaways affects how they run through a pass-through system, if you utilize one. They can raise he!! with conveyor sensors, throw timing off, send printers into a new cycle before the board
