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.

Our Manufacturing policy regarding welds is as follows. 1) Inner layers - depends on Core thickness and line width. Our shop will not do any welding on core thickness less then 5 mils. or line width less then 5 mil. Good AOI practices reduce the a

| I am looking to find a formula to calculate the resistance of circuit traces based on width | The old MIL-STD-275 became IPC-STD-275 became IPC-2221/2222. Anyway, they had/have simple graphic representations converting AWG standards into equivalen

Voltage does not flow. Current flows as a result of a change in voltage. Current capacity of traces * Graph is IPC-2221 paragraph 6.2, Figure 6.4 * http://www.geocities.com/CapeCanaveral/Lab/9643/TraceWidth.htm

You may be right. The assembly house also manufactures the PCBs. This might be referring to 8 thou trace width and 8 thou separation. Down to 5 and 4 thou. Could be...
