I noticed that some of our pcb's component legend/designation are unreadable as they are placed under smt pads. Is this correct and according to standard? Although we don't have any problems with them as of now, I would like to know the effects on th

I'm trying to design a costing matrix for raw cards so our designers can estimate the costs of their raw card designs, this will hopefully slow down their lust for technology and get them considering project budget costs. Does anyone know of where I

When double sided BGA's are used on an .062 FR4 10 layer board should via's be plugged and tented? The CACHE chips being used are PBGA's 1.27mm pitch. The pad size is .030 and the finished via dia. is .010. This is a dogbone type pad and via design.

When you say well designed for wave, does that include "extra" solder pads for the IC's for solder thieving? And Boards that are well designed for wave don't have QFP's on the bottom. They might be ok but then the board would be "ok for wave", but no
