Tinting / Plugging ot Test Vias
Tinting / Plugging ot Test Vias
(OP)
Hi
I am in the process of debugging a pcb as part of the design process. I have two different PCB vendors ( 1 works 1 does not).I have buzzed out the unit that is not working and the PCB seems fine. The only differance between the boards is the one that is working has the Test vias Plugged /tinted with solder mark.
(1) Has any one ever come accross an issue which pluggging the VIAs has made any differance to the functionality of a unit/ circut.

One other thing is to check that the plating in the vias is there, I have had one case where there was no plating in the vias and this caused nothing to work properly.
