Printed Circuit Board Double Sided Fr4 Pcb Board Assembly

 

 

What is a multilayer PCB(Printed Circuit Board)?

Since rigid circuits have some application requirements, different PCB designs are stacked into a single component. Multilayer PCBs are just the name suggests? They are made using two, three, or more circuit boards. Some manufacturers can assemble more than 30 different circuit layers on multiple circuit boards. The PCB has a rigid core, usually made of FR4 and copper. The core is then surrounded by copper foils and PrePeg fiberglass to form a laminate assembly. The process of making multilayer printed circuit boards varies from one manufacturer to another, depending on the board they want to create. A typical four-layer multilayer PCB will comprise of the following parts:

 

1. FR4 fiberglass laminate

This is the central core of the PCB. Because it provides support for the entire circuit board, this core must be rigid and processed for traces. The core is also slightly thicker than other layers added to the design.

2. Copper

Immediately after the rigid core is two copper layers that are engineered on either side of the core. The copper separates the core from the B-stage PrePeg fiberglass that makes up the next immediate layer.

3. B-stage PrePeg fiberglass

PrePeg fiberglass simply refers to fiberglass that is still soft and requires heating to make it rigid. The B-stage PrePeg fiberglass acts as the glue that keeps the inner FR4 core attached to the copper foil.

This layer is made up of thin, loose sheets of copper and is the outermost layer in the assembly. The copper foil is sandwiched together with the PrePeg and core then placed into a PCB lamination process.

4. Other elements

Multilayer PCBs can be single-sided or double-sided. Double-sided boards are more popular and feature interconnected copper patterns on the front and reverse side of the board. The design also features conductive plated-drill-holes (vias) that connect one side of the board to the other.

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.

Printed Circuit Board Application: 
Printed circuit boards provide us with a variety of capabilities and they find different applications in almost everything electrical or electronic.

Industrial Use
Many manufacturing facilities have electronic components that require printed circuit boards to achieve the end design. PCBs are found in industrial equipment such as presses, ramps, assembly machines, and more.

In the automotive industry, many vehicle systems such as navigation, media devices, control systems, and monitors are using PCBs.

Printed circuit boards also find applications in medical devices, such as CT scanners, X-Ray screens, and blood pressure monitors. All of the scanning equipment, medical instruments, and monitors contain PCBs.

Home Applications
The most common application of printed circuit boards is in consumer electronics. In fact, PCBs are the heart of every electronic device, such as mobile phones, computers, workstations, navigation, TV, microwave, coffee machine, refrigerator, and even your smartwatch.

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
