FR4 PCB Introduction

--Definition

FR means “flame-retardant,” FR-4 (or FR4) is a NEMA grade designation for glass-reinforced epoxy laminate material, a composite material composed of woven fiberglass cloth with an epoxy resin binder that makes it an ideal substrate for electronic components on a printed circuit board.

-Pros and Cons of FR4 PCB

• FR-4 material is so popular because of its many wondrous qualities that can benefit printed circuit boards. In addition to being affordable and easy to work with, it is an electrical insulator with very high dielectric strength. Plus, it's durable, moisture-resistant, temperature-resistant and lightweight.

• FR-4 is a widely relevant material, popular mostly for its low cost and relative mechanical and electrical stability. While this material features extensive benefits and is available in a variety of thicknesses and sizes, it isn't the best choice for every application, especially high-frequency applications like RF and microwave designs.

-Multi-layer PCB Structure

Multilayer PCBs further increases the complexity and density of PCB designs by adding additional layers beyond the top and bottom layers seen in double sided boards. Multilayer PCBs are built by laminating the various layers. The inner-layers, normally double-sided circuit boards, are stacked together, with insulating layers in between and between the copper-foil for the outer-layers. Holes drilled through the board (vias) will make connections with the different layers of the board.

Company Abstract

Abis Circuits Co., Ltd is a professional PCB manufacturer which was established on Oct, 2006 and focus on double side, Multilayer and HDI pcb mass production.

We have two factories together, the factory in Shenzhen is specialized in small and middle volume orders and the factory in jiangxi is for big volume and HDI.

Certifications

Rigid PCB Manufacturing Capacity

ABIS experienced in making special materials for rigid PCB, such as: CEM-1/CEM-3, PI, High Tg, Rogers, PTEF, Alu/Cu Base, etc. Below is a brief overview FYI.

Multi-layer PCB Manufacturing Process

• The process starts with designing Layout of the PCB using any PCB designing software / CAD Tool (Proteus, Eagle, Or CAD).

• All rest of the steps are of Manufacturing Process of a Rigid Printed Circuit Board is same as Single Sided PCB or Double Sided PCB or Multi-layer PCB.
