Here is the IPC Standards Tree [ http://www.ipc.org/4.0_Knowledge/4.1_Standards/SpecTree.pdf ]. The design standards that you ask about are over on the right side. I'd guess that the following standards would be a good starting point: * IPC-2221, "

The biggest factor is the selective solder machine. Do you want to know the minimum distance that all selective solder machines can handle with no difficulty? If so that will be a fairly large distance. If you are designing for in house boards then y

Stuart, My suggestion is a DFM meeting (most of the process people dream about a meeting like this, and luckily, I've been to a few) with: - project manager (if there's one) - customer service rep (annual volume, lot size, product life) - smt proce

Can anyone tell me if there is an industry standard on how much of a space should be between PCB's in a convection reflow oven? Thanks

It can also depend on the board. A board with 160 through hole BNC's requires more spacing than most boards.

Try an experiment where you profile the assembly with 3 consecutive boards in the oven spaced just 1" apart versus just 6" apart and then 12" apart. You figure most ovens have about 12 - 16" heating zones, so for your typical 8"x8" PCB, you'd have w

Assuming agressive design rules what is the minimum distance I can get away with between the board edge and a SMT pad and between the board edge and a plated mounting hole ??? (The board is only 1"x2" and the mounting holes are 80 mil dia, 125 mil

sometime hand solder can cause also. no necessary have to be paste n reflow.:) now i'm facing bridging on 0402 components pads. any suggestions on spacing distance as we're going to re-design the pcb.
