What is via?<\/strong><\/p>\n\n\n\n

A via plays an important role in multi-layer PCB<\/a>s. It is used to make an electrical connection between the layers of a multi-layer PCB<\/a>. Generally speaking, every hole in the printed circuit boards can be called as via.<\/p>\n\n\n\n

A via is constructed by placing copper pads on each layer of the PCB<\/a> and drilling a hole through them. And the hole is plated with copper that forms electrical connection through the insulation that separates the copper layers.<\/p>\n\n\n

Types of Vias<\/strong><\/p>\n\n\n\n

There are three main types of vias used in PCB<\/a>: through-hole via, blind via and buried via.<\/p>\n\n\n\n

Through-Hole Via<\/strong><\/p>\n\n\n\n

Through-hole via goes right through the printed circuit board<\/a> from top to bottom and can be used to connect all the layers of a PCB<\/a>. It is the most common via and is easiest to construct.<\/p>\n\n\n\n

Blind Via<\/strong><\/p>\n\n\n\n

Blind via connects the outermost layer of a PCB<\/a> to the next layer. Namely, it cannot be seen on the other side of the board and is therefore called blind via.<\/p>\n\n\n\n

Buried Via<\/strong><\/p>\n\n\n\n

Buried via is used to connect internal layers of a PCB<\/a>. And it cannot be seen on the surface of the board.<\/p>\n\n\n

In addition, it is always better to use multiple smaller vias rather than one large via since smaller vias can reduce the inductance and also provide an additional path to the current flow in case any of the vias fail.<\/p>\n\n\n\n
