Hi Mashak,
Thanks for the reply.
Does "close the mask" mean "tent the vias"?
Why would it cost more to allow vias to plate?
Thanks,
Mark

Hi,
Just close the mask
for the Vias which are close to the Gold Fingers. This will
save you additional cost.

Hi all,
Can anyone tell me concerns about vias being "too close" (.8mm or
.031") to gold plated edge connectors in PCB fabrication?
I know that vias "too close" will be plated Nickel / gold. Does
this create any concerns of integrity?
I would like to minimize redundant replies from vendors which
delay the delivery.
Any feedback is appreciated.
Thanks,
Mark
See image below.
We have a via keep out in our lib parts set to 20 mil above plated
pins. Our vendor response is as follows:
The via solder
mask opening is too close to the gold fingers, so it will be
plated Ni, Au.
And also the via pad will have immersion gold when we are
plating surface treatment.
We suggest to cancel the via holes solder mask opening where
the distance is less than 0.8mm to the gold fingers.
Their suggestion is:
A.
Accept our suggestion.
B. Follow Gerber, but accept the via pads will be plated
Ni, Au.
