Buried Via PCB Manufacturing

Buried vias connect only inner layers inside printed circuit board so that they are invisible just from the outer appearance of a PCB since they are internally "buried".

Laminate : CEM-3
Type : Rigid-flex
Layers : 8 Layers
Application : Others
Surface Finish : HASL
Copper Thickness : heavy copper
Laminate Thickness : 1.0mm

Buried Via PCB Manufacturing

Vias, that is, copper plated holes, play a key role in the interconnection between layers in a printed circuit board. Generally speaking, vias in PCBs can be classified into the following categories: through-hole via, blind via and buried via. Blind/buried vias are widely applied in SMT (Surface Mount Technology) just to compensate for disadvantages of through-hole vias.

Buried vias connect only inner layers inside printed circuit board so that they are invisible just from the outer appearance of a PCB since they are internally "buried".

Costs and Quotation of Buried Via PCB Manufacturing

The total costs of buried via PCB manufacturing and assembly services are mainly determined by PCB dimension, laminate thickness, surface finish, layer(s), other special technical requirements (such as blind & buried via, impedance), components, numbers of soldering pads and test plan. You can send PCB files (Gerbers) and BOM to get instant quotation within 24 hours.

Due to our over 10 years' experience in this industry, NOD Electronics specializes in manufacturing PCBs with blind/buried Vias. Both engineers and manufacturing equipment from NOD Electronics ensure our full capabilities in meeting the requirements of blind/buried via technology.
