Product Description

FR4 multilayer pcb board assembly Manufacturer Rohs Circuit Board

 

 

FR4 multilayer pcb board introduction:

FR-4 (or FR4) is a grade designation assigned to glass-reinforced epoxy laminate sheets, tubes, rods and printed circuit boards (PCB). FR-4 is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant (self-extinguishing).

"FR" stands for flame retardant, and denotes that safety of flammability of FR-4 is in compliance with the standard UL94V-0. FR-4 was created from the constituent materials (epoxy resin, woven glass fabric reinforcement, brominated flame retardant, etc.) by NEMA in 1968.

FR-4 glass epoxy is a popular and versatile high-pressure thermoset plastic laminate grade with good strength to weight ratios. With near zero water absorption, FR-4 is most commonly used as an electrical insulator possessing considerable mechanical strength. The material is known to retain its high mechanical values and electrical insulating qualities in both dry and humid conditions. These attributes, along with good fabrication characteristics, lend utility to this grade for a wide variety of electrical and mechanical applications.

NEMA is the regulating authority for FR-4 and other insulating laminate grades. Grade designations for glass epoxy laminates are: G10, G11, FR4, FR5 and FR6. Of these, FR4 is the grade most widely in use today. G-10, the predecessor to FR-4, lacks FR-4's self-extinguishing flammability characteristics. Hence, FR-4 has since[when?] replaced G-10 in most applications.

FR-4 epoxy resin systems typically employ bromine, a halogen, to facilitate flame-resistant properties in FR-4 glass epoxy laminates. Some applications where thermal destruction of the material is a desirable trait will still use G-10 non flame resistant.

Types of FR4 PCB: 

1. Single side FR4 PCB

The Fr4 single-side printed circuit boards are made of epoxy resin PCB having copper foil on one side, its components are pasted on one side.

2. Double side FR4 PCB

The Fr4 single-side printed circuit boards also are made of epoxy resin PCB having copper foil on one side, but its components are pasted on two sides which give the path of traces to cross each other.

These boards contain copper for conduction.

3. Multiple layers FR4 PCB

The multisided PC board has more than two layers. It contains three layers of material for conduction.

That is pasted in the center of the materials. The core material is laminated together under high pressure and high temperature to produce multilayer PC boards. Components are pasted on both sides of PC boards.

4. Rigid FR4 PCB

In this type of Fr4 PC board, the core materials used are only Fr, so that is why this is called a rigid fr4 printed circuit board.

There are no other materials or impurity added to it it’s a pure circuit, that is why it is rigid for the whole PC board.

5. Rigid-flex FR4 PCB

In this type of PC board, the core material is rigid as well as flexible so they are called rigid-flex Fr4 PC boards.

The flex is due to circuit flexibility. We used thin boards because it is more flexible and more vulnerable to heat.

During soldering, it can be bending to make a desirable angle.

The process of making a multilayer PCB: 

Several factors go into producing high-quality multilayer PCBs. The process involves specific steps necessary to ensure every aspect is covered. Since there are different types of multilayer boards, the manufacturing process may be different based on the unique design you want to achieve. Besides front end planning, the general procedure involves:

·  Photo plotting – converts the photo data and converts it to the image pixel .

· Imaging and DES (develop, etch, strip) – applies the primary image on to the PCB .

·  Automated optical inspection – inspects the layers of the multiplayer PCB before lamination .

·  Oxide treatment and lamination – chemical treatment applied to the inner layers of the PCB. Lamination binds the different layers of copper and fiberglass together .

· Drilling and electroless copper deposition – this process creates the required drill holes and trenches on the PCB. They are then covered by copper deposits .

 Electrical test, fabrication, micro-sectioning, and final inspection
