To
build up a circuit, it is necessary to have a strong electrical
connection between two layers of the PCB. In this way, the transition
will take place smoothly. The PCB via in pad is used in this situation. The VIA, is the electrical connection, that helps to establish the connection between two layers.
Via
or the vertical interconnected access is used when the two board of the
PCB is connected through a hole. The hole has to be conductive enough,
and electroplating is used for it, get associated with the rivet or the
tube. So if you are planning to get a circuit, you have to be aware of
these issues.
The
VIA is made out of many materials, and these are pad, barrel and anti
pad. The Pad helps to connect every end of the barrel with the basic
components or trace or the plane. If the board gets separated, the VIA
may get cut in half, as this is situated at the end of the board.
The
PCB via in pad is also known by the name of the castellated hole, and
there are plenty of reasons to use it. This helps the printer circuit
board to get soldered with another, when they are in the position of
stack.
There are three different kinds of VIAs and this helps to repeat the various layers of the PCB. In this process, of PCB via, there has to be more than two layers to stack. This is applicable on the double sized PCB and the process starts with the core.
The
holes of the anti pads are cheaper, but if you want to use the circuit
which is in the best working condition, then you have to opt of the PAD.
You have to gather all the possible information, and in this way you
will be able to have the best quality of the circuit of your personal
use.
