This is a question for those of you who actually assemble components onto a board. Any idea what the "industry standard" is for fall out on assembled PCB's? I realize that the controls put in place in your processes will effect your overall quality

Q1. Do we really need to follow the IPC J-STD-001 Solder purity? A1. Yes, you should control impurities in solder. Further information: * "Allowable concentration of contaminating elements in solder: impurities are harmless unless their level goes to

Hi, Our engineering board has to decide which technology is better for the hand soldering of the SMT components: HASL or Chemical Ni-Au. We have an automatic line for SMD assembling and our experience shows us that for this automatic line is better

I can't seem to locate any information/concerns about moisture entrapment in IC packages on the promary side in a double sided SMT assembly using water soluable solder paste when soldering the second side. A typical process would assemble/reflow/cle

Hi All, I've been in the CM world for a long time and it seems like there has been little change in the packaging techniques used at the end of the day. Assembled circuit boards in small/flex volume are bagged or bubble wrapped and boxed up to ship

this is very touchy.There are many CPMs out there. Which one is the best for you though is what you should figure out. I think your boards density, quantities and variety assemblies will define that. One of our customers has around 1000 different ass

How you pack & ship your board level assemblies? I mean assembled PCB modules without housing etc. We often have small assemblies (cigarette box size) in the $5-15 range. We put them the (dreadful) red bubble bags and then on carton trays with carto
