I have a large monoblock ceramic filter on a PTFE based pcb material. The filter has a metal casing soldered onto the ceramic filter. I am concerned that if the heating rate is to rapid, then thermal shock / differential expansion could cause the fil

Soldering PTFE boards * Exposure to the high temperatures needed for solder reflow poses no problem of loss of peel strength since the exposure times are relatively short. * There are many different types of PTFE based products that may perform diff

We have a board that has an RF shield on one side and ceramic capacitors on the other side. The side with the capacitors is reflowed first, then the other side is reflowed. We have been experiencing cracked capacitors in these boards. My guess is tha

Working DFM SMT issues with respect to a client's artwork together with a heavily modified solder stencil, I was able to reduce 0402 tombstoning from 80% across the board to 3%. I winged the aperture reductions, but are there any "rules" or guidelin

Does anyone know what the voltage ratings on ceramic caps is related to? Would it be safe to use a 50V cap instead of 25V for .01uF X7R bypass/filter caps? Thanks Russ

Ceramic caps are denser than most other components and I"ve found the tops can be slightly rounded. You may want to slow down the turret speed for some parts. Do you ever get a location where there should be a part but there is not? If the part fly
