Via
Filled PCB Via in Pad Circuit Board 0.6mm Multilayer PCB Built On 6 Layer With
Blind Via for GPS Tracking
(Printed
circuits boards are custom-made products, the picture and parameters shown are
just for reference)
1.1
General description
It's only 0.6 mm thick
without silkscreen on green solder mask (Taiyo) and immersion gold on pads. The
base material is from Taiwan ITEQ supplying 1 up PCB per panel. Vias with
0.25mm areresin filled and capped (via in pad). They're fabricated per IPC
6012 Class 2 using supplied Gerber data. Each 50 panels are packed for
shipment.

via in pad (VIP)
At
present, the circuit board is becoming more and more dense and interconnected,
and there is no more room for these wires and pads connecting the holes.
Therefore, so in this context, the process of punching the holes on the pads
arises at the historic moment. In brief, the via holes which have been plated
through are plugged or filled by insulating resin through the method of screen
leakage, and then drying, grinding, and then electroplating, so that the whole
surface of the PCB is coated with copper, and no longer via holes can be seen.
The
effect of via in pad is also very obvious: such as improved the electrical performance
and reliability of electronic products, shorten the signal transmission wire,
reduced the inductive reactance and capacitive reactance of the transmission
line, and reduced internal and external electromagnetic interference.
Let’s
see the basic process of via in pad.
