Buried Via PCB Assembly

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".

Type : Aluminum
Layer(s) : 4
Laminate Thickness : 1.0mm
Copper Thickness : 1oz
Surface Finish : HSAL
Transport Package : Vacuum
Certificates : RoHS

Buried Via PCB Assembly

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".

Buried Via PCB Assembly Process Control

AIRMEND fully show respect to your strict confidentiality of documentation and procedures and has formalized a range of control process that can ensure customer products in delivery of good quality. We will operate the process during Incoming Quality Control (IQC), In-Process Quality Control (IPQC), Outgoing Quality Assurance (OQA) etc stages and management methods ISO, 7 sigma, PDCA.

PCB Assembly Process

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

Up to now, we're capable of providing mechanically drilled and laser drilled solutions. When it comes to mechanical drilling, via diameter ranges from 0.2mm to 0.4mm while 0.1mm for laser drilling.
