What are people using out there for minimum spacing between vias ? We recently came across a PCB manufacturer that wants us to increase our spacing due to their process. Below is our current spec. that we follow. Spacing between via pad to via pad o

IPC 2221B mentions a minimum clearance of 0.5 mm between adjacent holes. A drill-to-drill spacing of 20 mils is a standard value in manufacturer design rules. For small annular rings and pad-to-pad clearance, the minimum via distance is often defin

Thank you Robi, I tried. Officialy service answered that they are not supporting this machine. So I'm looking for alternative method. Maybe some of you still have this machine, or you know when I can get spare parts (perhaps somewhere in Asia they co

All termination platings are not created equal (sic). Some parts put up more of a fight against wetting than others, and in those cases you really have to dial it in. It seems like that in most of those cases I end up reducing the temps in the midd

Did you solve this issue? It doesn't much look like the flux dried out, ti should be across whole board and has much more same defect if flux dried out. Did you have failure ratio data to show the defect location, for example 10% at location A on bo

You might want to try baking the LED's in an oven for 24 hours prior to build. We keep our LED's in a humidity cabinet all the time, as we have noticed poor solderability if they are left out for too long. This may be even more important when buying

The one thing I haven't seen mentioned yet is developing the the control systems for the process equipment and materials. You don't want to mix up your solder paste, bar, and wire, and you don't want to cross-contaminate by using equipment (solderi
