Microvia PCB

All You Need to Know About Microvia PCB

Today microvia PCBs are commonly used in almost every electronic device, big or small. These PCBs are designed with a new technique Microvia that helps in saving space as well as the cost of designing various types of PCBs. Before discussing more these PCBs you must know what Microvias are?

What are Microvias?

Microvia PCB

Microvias are tiny holes on the circuit board through which high-density interconnections or HDI are made to complete workable printed circuit board. The diameter of microvias is even less than 150 m which cannot be drilled without using special devices like lasers. The main benefit of using a laser technology for drilling microvias is that it can reduce the size of the hole even up to 15 m to save more space on the PCB, if possible. Moreover, chances of a manufacturing defects are very low while drilling microvia PCBs with laser technique as compared to PCBs with normal vias. But the risk of reflow of plating and solder remains the same as with normal via PCB.

Benefits of microvia PCBs

A microvia PCB offers two types of benefits, space and cost-saving and reducing noise in audio circuits.

Space and cost-saving benefit

The space saved on a PCB helps in lowering its cost. In this way, microvia PCB becomes affordable for all. The smaller size of microvia will naturally save the space on the PCB more than the PCB with normal vias. Microvias can also help in making HDI design easier and improving the utilization of buried vias in pads or VIPs. VIPs help in saving space while making connections, using surface mounted technologies or SMTs, inside the pad. The smaller size of microvias makes them more suitable for VIPs instead of normal vias as microvias can be used inside the pad without any problem. When space is a constraint, micro ones come handy.

Noise-reducing benefit

Sometimes you have to listen to noisy music which is caused due to the inappropriately made PCB of your music system. A
