7:51 am Posts: 1 Location: India We are a manufacturer of
RF modules in Ku band.The shift of conductor edges in PCB manufacturing
is very important for us(as you know it leads to change in trace width,stub
length,....).To avoid tuning in our production line the shift must be
less than 10 microns(This leads to 20 micron shift in trace widths -
with 10microns for each side). As far as we know this shift is due
to lithography and etching tolerances.does anyone know an Rf PCB manufacturer
who meets our requirements.Is there any idea about other manufacturing
error resources.
thanks
