Multilayer PCB refers to is a circuit board with three or more conductive copper foil layers. All multilayer PCBs must have at least three layers of conductive material that are buried in the center of the material. In comparison with single-layer PCBs, multilayer PCBs are smaller in size and lighter in weight, besides, multilayer PCBs are much more powerful than single-layer PCBs. Multilayer PCBs are widely used in applications such as consumer electronics and telecommunications with high assembly density and enhanced design functionality.

Flexible PCB Manufactring Process Flow Chart (Free Download PDF)

1) What is a Flexible PCB?

A flexible printed circuit board also called flex circuit board, flexible PCB, flex circuit, flexible printed circuit or flex PCB, is a combination of several printed circuits as well as components that are positioned on a flexible substrate.  flex circuit boards, flex PCBs, flex circuits, or flexible printed circuits. These printed circuit boards are designed using the same components as rigid printed circuit boards. However, the only difference is the board is made such that it flexes to the desired shape during the application. Flexible circuits are basically made from a thin insulating polymer film with a pattern of conductor, adhesives, and Insulators. Flex circuits have been in use since the Second World War and their applications are still growing exponentially. Flexible printed circuit boards are widely used in avionics, airbag systems, antilock brakes, bar code equipment, battery packs, cameras with their flexibility and high heat dissipation, it is also cost savings.

The FPCB can be divided into to types:

● Rigid-Flex PCBs
● HDI Flexible PCBs

2) How is a Flexible PCB Made?

Flexible PCB Manufacturing Process can be divided into: 

Shearing >> CNC (Computer Numerical Control) Drilling >> Plating Through Hole >> Dry Film Lamination >> Exposure >> Developmen >> Etching >> Stripping >> AOI (Automated Optical Inspection) >> Coverlay Pre-Lamination >> Hot Press >> Metal Finish >> Screen Printing >> Test

RTR is a new generation of FPC production methods. The main feature of the RTR method is that it can complete the whole front process, from drilling to hot press, of all the FPC at the same time. Therefore, once the RTR method reaches its stable capacity, the production efficiency will have a great enhancement. Given the advantage of the RTR method, many manufacturers have made investments to equip the RTR production line.

3.5 What is a Rigid PCB and How is a Rigid PCB Made?

Rigid PCB Manufactring Process Flow Chart (Free Download PDF)

1) What is a Rigid PCB?

A rigid PCB is a board that we cannot bend or force out of shape, once a Rigid Circuit Board is manufactured it cannot be modified or folded into any other shape. It is a solid, inflexible printed circuit board made up of copper trances and paths that are incorporated on a single board in order to connect the different components on the board.

Rigid PCBs can be anything from simple single-layer PCBs to eight or ten-layer multi-layer PCBs. It is the largest number of PCB manufactured, the base material of the board is made of a rigid substrate which gives rigidity and strength to the board, which can effectively prevent the distortion of the circuit board.

Rigid PCBs can be anything from simple single-layer PCBs to eight or ten-layer multi-layer PCBs. They are widely used in Computers and Laptops. The computer motherboard is the most common rigid PCB. The motherboard is a multi-layer PCB designed to distribute power from the power supply while allowing communication between all components of the computer, such as CPU, GPU, and RAM.

Rigid PCBs are also widely used in military and defense equipment, automotive, hand help devices, and industrial equipment, etc. for its cheap cost, durability, and high quality.

2) How is a Rigid PCB Made?

A  Rigid PCB Manufacturing Process can be divided into:

3.6 What is a Rigid-Flex PCB and How is a Rigid-Flex PCB Made?

Rigid-flex PCB Manufactring Process Flow Chart (Free Download PDF)

1) What is a Rigid-Flex PCB?

A rigid-flex printed circuit board (PCB) can be divided into two types, which are "installing flex" and "dynamic flex". As a hybrid circuit board design that using a combination of flexible and rigid board technologies in an application, rigid-flex printed circuit board integrates elements from both hardboard and flexible circuits. The flexible layers are buried internally and completely penetrate the rigid sections of the PCB, so the board is rigid at some points and flexible at others... And because of this, rigid-flex circuits can be folded or continuously flexed while maintaining the shape of areas that need extra support. 

Flex and rigid-flex circuit boards act as a replacement for wire and wire harness assemblies, providing cost savings with no reduction in performance.

Also, rigid-flex PCBs are widely used in high-shock and high-vibration environments because this type of PCB is highly shock-resistance, space-saving, cost-saving, and highly reliable.

3.7 What is a High-Frequency PCB and How is a High-Frequency PCB Made?

RF PCB Manufactring Process Flow Chart (Free Download PDF)

1) What is a High-Frequency PCB?

High-Frequency PCB is a type of PCB available in the frequency range of 500MHz to 2GHz. In general terms, the PCB industry considers an RF circuit board to be any high-frequency PCB that operates above 100MHz, generally speaking, high frequency can be defined as frequency above 1GHz. Currently, PTFE material is widely used in high-frequency PCB manufacturing, it's also called Teflon, which frequency is normally above 5GHz. In addition, FR4 or PPO substrate can be used to the product frequency among 1GHz~10GHz.

A high-frequency PCB is an ideal choice for mobile, microwave, radiofrequency, and high-speed design applications, it can meet your needs when incorporating a special signal requirement into your electronic components and products. 

There are plenty of "things" that need to be taken into consideration when designing a High-Frequency PCB, for example, the dynamic dielectric constant, the coefficient of thermal expansion, loss tangent, spacing, moisture absorption, cost & perfomance, if you leave one of these "things” behind when producing an RF PCB, you might make some mistakes.

2) How is a High-Frequency PCB Made?

High-Frequency PCB Manufacturing Process can be simply divided into: 

● Layout - Design - PLating - Routing

However, due to the high itegration and diffculties in making high-frequency PCB, many steps needs to be taken very carefully, FMUSER hereby provide a simple list of high-frequency PCBmanufacturing process steps for you, if you would like to know more information about making or designing professional RF printed circuit board, please make sure to contact our techinical team, we're always listening!

Aluminum-backed PCBs are the perfect thermal heat dissipation solution famous for their high performance, including excellent thermal conductivity and electrical insulation. It is a type of printed circuit board with a bonded copper circuit layer to create superior heat transfer to help cool components while eliminating problems associated with managing fragile ceramics, which especially friendly for any design that utilizes high power surface mount ICS. An aluminum-backed PCB contains a thin layer of conductive dielectric material. They are also known as Aluminum Clad, Aluminum base, MCPCB (Metal Clad Printed Circuit Board), IMS (Insulated Metal Substrate), Thermally Conductive PCBs, etc. Aluminum PCBs typically are single-sided but can be double-sided as well. Multilayer Aluminum PCBs are highly difficult to manufacture.

Aluminum boards get the most use in LED and power converting electronics, because of the characteristic of being light-weight, able to dissipate heat, long lasting, easy-assembling environmentally friendly,and economical, Aluminum-Backed PCBs are also widely used in healthcare (surgical lighting tools and medical operating theatre lighting), automation industry (automotive dashboards), transmission (signal beacons), etc.
