we have some problems in soldering joints such as insufficient solder and misalignment on some RC0402 and CC0402,i don't have a pic here. our SMT enginner doubts the PCB land pattern is at the fault.here is what we measured results.pad length:0.9mm,

Hi, check the Land pattern 0201 on the board, compare with another 0201. Could be different gap.,

SMD land patterns design for wave soldering

I' designing a PCB with SMD components to optimize the land patterns for wave soldering. I find that the IPC-SM-782 land patterns are not robust enough for wave soldering, yielding ramdom skips and bridges. This PCB will also give me insight on sha

Thank you all for your quick reply ! the problem is solved without making any intervention on line .. 0% defect rate for the moment .. for all of you who said "try rotating the board 180 °", we can't do that because the panel contains 2 boards head t

Your thinking is correct. Wave soldering pads that were designed for reflow can create problems: * Large pads used for reflow [too much solder] can create reliability problems. * Bridging [too much solder] creates rework. * Skipping & shadowing from

Min spacing for land patterns from PCB edge

Hi! Can anyone tell me what is the min spacing between PCB edge & land pattern to avoid cracking of components due to mechanical stresses caused while depaneling with cookie/pizza cutter. Thnx!
