Multilayer PCB By Feature

4 Layer PCB

There are 4 Layer PCBs available, made with good prepregs. Megtron 6 and Rogers are two of the materials that are included. They can be used in a variety of mid-range electronics applications.

6 Layer PCB

Customers who require standard Copper PCBs but have a limited budget can benefit from the 6 Layer PCB. The copper layer is completely protected from lead or tin corrosion with Hot Air Soldering.

8 Layer PCB

The 8 Layer PCB is very cost-effective. Motherboards, Graphic Cards, SSDs, and laptops have them as essential components. It is used in many digital industries.

10 Layer PCB

The 10 Layer PCBs, some rigid, others rigid-flex, are assigned to mobile device sizes. These also work with gadgets that have a regular shape. The product has a strong PCB core that ensures optimal performance.

12 Layer PCB

Circuit board makers must be trusted by electronic designers and PCB engineers. They must correctly put transistors, inductors, ICs, and other critical pieces on a 12 Layer PCB during assembly.

14 Layer PCB

Our 14 Layer PCB is made of FR4 and sturdy fiberglass. We make this versatile item last longer, just like the finest firms. In addition to various USB PCBs, we also mass produce CPU PCBs.

Multilayer PCB By Board Thickness

0.8mm Thickness PCB

It is designed for purposes that are commonly associated with ordinary FR4 and has a board thickness of 0.8mm. Customers that need a medium TG board may additionally want a High TG 150 or High TG 170 PCB.

1.0mm Thickness PCB

After 0.8mm, the 1.0mm High TG PCB is the next step forward. In terms of tolerance, a thick PCB will perform better. This PCB is also wet and chemically resistant to a degree.

1.2mm Thickness PCB

Immersion Gold is a popular surface treatment for the 3.2mm Multilayer PCB. In terms of advantages, the ability to etch surfaces into various designs would be one of its most appealing features.

1.6mm Thickness PCB

The rigid versions of the 1.2mm Multilayer PCB can be used in medical devices and other applications. This type of space efficiency due to thickness is really beneficial for commercial applications.

2.4mm Thickness PCB

Our 2.4mm Multilayer PCB is a versatile product with many applications thanks to its excellent stability. It is also quite long-lasting. Because multilayer PCBs like these are in high demand, mass manufacture is normal.

3.2mm Thickness PCB

Immersion Gold is a popular surface treatment for the 3.2mm Multilayer PCB. In terms of advantages, the ability to etch surfaces into various designs would be one of its most appealing features.

Multilayer PCB Definition

A PCB is called Multilayer PCB, if it has 3 or more layers(sheets) of copper foil, insulated from each other(by lamination or coating) and joined together to form a single piece.

A Multilayer PCB has an Inner Layer Core present at the center of all the layers and coated with a Copper layer from both sides, while layers of prepreg(woven glass cloth with epoxy resin) are used for insulation.

In Multilayer PCB, outer layers(top & bottom) are single-sided PCBs , while the inner layers are double-sided PCBs .

What is PCB Via?

In PCB terminology, Via is a copper-layered hole, used for connecting different layers of Multilayer PCB.

There are 3 different styles of Vias available, discussed as follows:

Through-hole Via: This Via connects all layers of a multilayer PCB from top to bottom.
Blind Via: This Via connects any outer layer(top or bottom) with one or more inner layers of Multilayer PCB.
Buried Via: This Via connects any number of inner layers and never connects with any outer layer(top or bottom).
