The Basics about Flexible PCB Manufacturer & Aluminum PCB Manufacturer

Understanding of the standard circuit board is important to comprehend the concept of Flexible and Aluminum PCBs.
 

Standard PCB

Printed Circuit Boards or better known as PCB is an electrical circuit whose conductors and components are put together within a mechanical structure. Conductive Planes, heat sinks, pads, and copper traces are conductive features. The mechanical structure includes the insulating material laminated between layers of conductive material.

To create a robust and strong PCB, layers of nonconductive insulating material alternates with conductive copper layers. For the circuit board connection, PCB manufacturer etches the copper layers in order to leave traces of copper.

For more detail on the basics of PCB, you can read our systematic guide on the Printed Circuit Board.
 

What is Flexible PCB?

As the name suggests, Flexible PCB allows circuitry customization.  Unlike Standard circuit boards, where you need to design the machine according to the PCB requirements, with Flex PCBs, you can now develop circuitry in accord with the needs of the product or the electronic device.

A malleable base material highlights the flex circuit board’s component arrangement and a distinct patterned print characterizes the entire board. Flexible PCB can be either single-sided or double-sided.  Which one is better, solely depends on your requirement.
 

Manufacturing Process of Flexible PCB

Flexible PCB has the ability to satisfy the needs of contemporary electronics as it is lightweight, has an agile structure and offers good quality. Flexible PCB can extend to three dimensional, thus it offers freedom of mechanical structure design and circuit design.

Some Flexible PCB Manufacturers even offer the facility of Flexible PCB Prototype manufacturing.
 

Pre-treatment

A well-designed pre-treatment process prevents low yield caused by defects in the production process including short circuits or open circuits. It can enhance the coarse problems such as cutting, rolling, and drilling to reduce feeding frequency.
 

Single-Sided Flexible PCB Manufacturing Process

The first step is cutting the PCB, after that all the required drilling takes place. Next, is the step for drying film lamination and positioning and exposure? Then, the PCB manufacturer works on the Development and etching of Flex PCB.

Removal of Dry Film comes next, then surface finish,  CoverLay Lamination, Lamination and curing of the circuit takes place. After these important steps come, the surface finishing and the impression Gold. Then the Silkscreen is applied, and scoring or V-cutting happens. Since the circuit is almost ready, electrical tests start along with punching and FQC. Finally, after ensuring `everything is complete, the packaging comes into action. Lastly, the PCB is shipped to its destination.
 

Double-Sided Flexible PCB Manufacturing Process

There is a small difference when it comes to double-sided Flexible Printed Circuit Board manufacturing process.

Like single-sided, double-sided Flex PCB manufacturing process also starts with cutting and drilling. After that, the PTH step takes place, along with the electroless plating. Then it is pretreating, Dry Film Lamination, and Position.

Then comes the exposure step followed by developing and pattern plating. Manufacturers meticulously remove dry film and do the pre-treatment again. They head towards dry film lamination, position, and exposure and then they enter the developing phase.

After developing, come etching and again they remove the dry film. Now, the surface finish and coverlay lamination come into action. Lamination, curing and immersion gold are the next steps in line. Then they use the silkscreen, scoring or v-cutting. Before the punching, comes electrical test and then FQC. Finally, the packing and shipping take place.
 

Advantages of Flexible PCB

There are several advantages offered by the Flexible PCB. However, to ensure that you can fully enjoy these benefits, a Flexible PCB Manufacturer should pay close heed to the production process. They should meet the highest standards of manufacturing.

Since Aluminum PCBs are a part of a good number of modern applications, thus we see a wide range of Aluminum PCB Manufacturers.  Several affordable and cheap PCB manufacturers are also among the biggest Aluminum PCB exporters including KingPCBs.
 

What is Aluminum PCB?

Aluminum PCBs are excellent thermal conductors mainly because they feature metal based-copper clad laminates. These Printed Circuit Boards are famous for being outstanding electrical insulators as well.

The base material of the Aluminum PCB consists of aluminum. The circuit tends to dissipate heat in an effective manner due to its thermal clad layer. In addition, the clay layer is also useful for cooling components and increasing the overall performance of the electronics and other products.
 

Manufacturing Process of Aluminum PCB

The manufacturing of Aluminum PCB is different from the standard Printed Circuit boards.  It is said to a daunting task, manufacturers consider among the most challenging undertakings. The main difference between the standard PCB and the Aluminum PCB manufacturing process lies between the chemical milling steps.

The Aluminum PCB Manufacturers add a fragile layer of dielectric between the circuit layer and the base layer. The reason for adding this layer is to increase the electrical insulation capability and thermal conductivity.

The next step is achieving the pattern. In order to achieve the pattern, you need to etch the copper foil, right after adding the dielectric layer. The thin dielectric layer along with a good metal base layer removes any heat that might exist in the circuit.

The three main production processes including copper etching, solder mask printing and mechanical manufacturing of the circuit require expertise and exposure. They need to be completed to perfection in order to create a robust, reliable and long-lasting circuit.
 

Advantages of Aluminum PCB

Aluminum PCB Manufacturers firmly believe that they have several advantages in comparison to Flexible PCB manufactures as well as standard PCB manufacturers.  Below are the reasons that support their claim.
