I agree with Jerry. We don't use 5 mil until we get to .4mm pitch.

use electropolish 5 mils stencil & bonetype aperture

Thanks very much everyone. I'll try out a 5mil and see how that goes.

Hello there, I work at Redcom Laboratories in Victor NY. I'm a student and new to being a machine repair technician. I'm having some bother with one of our TYCO QUAD QSP-2 machines. I keep getting the errors: "WARNING: Head#2 Nozzle RUNOUT=27.1 mi

Probably because boards get designed with a required route to be 5 mils from some copper.

Please check what is the actual pitch size. I found some of the designer use 15.7 mil pitch and no accumulate ie 15.7, 15.7 and 15.8...... Also, I recommended the pad width should be 10 - 11 mil for 0.4mm pitch. You can open the 10 - 10.5 mil aper

Can someone helps to interpret the IPC-A-610's requirement on solder balls ( less than 5 mils in diameters.). We found about 6 to 10 balls ( less than 5 mils ) scattered in a 600 sq mm board. Is it consider failing for class 2 product ?. Thank you.

| Can anyone in this world produce such small PCB/PWB trace widths? Lots of theory so far, but have not found anyone yet who can do it in practice. | Dan, I have seen boards with 3 mil pitch (that is 1.5 mil trace and 1.5 mil spacing) in quantity

I'm in 100% agreement with the 5 mils foil. In applications where there is less than 20 mil pitch actives and less than 0603 discretes 5 mils does great and increases your operating window by a ton it's less sensitive to release and print accuraccy.

If the PCB you are using is a HASL pad finish and is a leaded assembly, we use homeplate pads with a 5 mil stencil. If the circuit has Enig finish and is PB-Free then we use 1:1 apertures with a 5 mil stencil Either method should provide no solde
