How to Manufacture Microvia PCB Board?

Microvia PCBs constitute a core part of today's electronic products, and these help in small size and high output. These multi-layered circuit boards find applications in electronics such as smartphones, medical technology, automotive, and high-speed communication and many more. We are capable of providing full-service package including design, fabrication and assembly as a professional microvia PCB manufacturer.

What is Microvia PCB Board?

A microvia PCB is a type of HDI PCB which uses microvias to connect adjacent layers in a circuit board. Microvias are tiny holes, generally with a diameter of 0.006 inches (150 microns) or less that allow for greater wiring density and smaller designs. These circuit boards have small vias, narrow lines and spaces, and high I/O and are granted by complex interconnections attributed to microvia technology in a small space for occlusion.

How to Manufacture a Microvia PCB?

The production procedure of microvia PCBs is a combination of high-tech products including life science and electronics.
Material Selection Process
The first step in the process is the appropriate material selection with importance given to thin dielectric layers and copper foils which promote high-density circuits of the HDI PCBs. As a professional manufacturer, we select the materials with good thermal and mechanical characteristics for durable and stable microvia PCB.
Laser Drilling
The production of microvias is the most critical process in manufacturing Microvia PCB. Laser drilling enables these holes to be drilled with very high accuracy. This method enables precise interconnections between layers without compromising the integrity of the board. 
Plating and Filling
Following drilling, copper is plated in the microvias to create electrical connectivity between layers. Sometimes, the microvias are filled to make up for an uneven surface for to lay down more layers. This step is essential for making sure the PCB is reliable, especially so in demanding HDI applications.
Layer Lamination and Circuit Etching
The pcb layers are the laminated under heat and pressure to consolidate the lamination into a rigid unit. Then more sophisticated etching is carried out to produce the complex circuit patterns needed for high-density designs.
Surface Finishing and Testing
For board protection and better solderability, surface finish such as ENIG (Electroless Nickel Immersion Gold) or OSP (Organic Solderability Preservative) are used. In the end, the PCB is subjected to the testing to ensure it has the desired performance.
