Top 5 Polyimide PCB Manufacturers in the World

Different kinds of Printed Circuit Boards (PCBs) exist, but the Polyimide PCB has been getting the attention lately. This article highlights the top five (5) manufacturers of this type of PCB.

What is the Polyimide PCB?

It is a type of circuit board made with Polyimide, which is a flexible material used for the production of circuit boards. According to Hillaman Curtis, the Polyimide used in the circuit board is also a set of “polymers that have imide monomers.”

The general submission is that the Polyimide PCB is a type of circuit board that is used in applications that require utmost flexibility.

Polyimide PCB vs. FR4: Which is Better?

There is an ongoing debate on which is better between the Polyimide PCB and the FR4. Worthy of mentioning is that the Polyimide PCB breaks through the conventional use of the Flame Retardant Level 4 (FR4) type of PCB material because of the additional characteristics.

The FR4 is commonly known for the zero-water absorption, which makes it ideal for use with the standard applications. However, the FR4 material cannot be used with the applications that have been manufactured.

It is therefore, on that basis, that the Polyimide PCB proves a worthy replacement, owing to the “universality” that allows for the use with the flexible PCBs and the rigid-flex PCBs.

The flexibility of the Polyimide PCB that makes it ideal for use with the flexible PCBs can be attributed to the “stiffness” attributed to the FR4 Materials used for PCB design. For the PCBs relying on the FR4, they don’t always end up being flexible because the material gets stiff due to the combination of the copper lamination and the epoxy glass glue used on it.

However, the FR4 material proves to be a cost-saving variant to the Polyimide PCB, in the sense that it saves the consumers a considerable amount of money. The cost-saving design is derived from the Polyimide PCB’s extensive use, which makes it expensive.

Choosing a Polyimide PCB Manufacturer

The selection of the best Polyimide PCB manufacturer has to do with a lot of background checks on the prospective manufacturer’s integrity. Even at that, you don’t want to ignore the following factors:

Customized Solutions

One of the things to look out for is the Polyimide PCB manufacturer’s readiness to offer tailored solutions. The customized Polyimide PCB solutions should align with the customers’ needs and the industry’s requirements.

Can the Manufacturer Make Polyimide PCB Variations?

Is it possible for the manufacturer to move beyond offering customized Polyimide PCBs to making different variants of the circuit board?

While the Polyimide PCBs are a popular choice for use in making flexible PCBS, they can also be made into other forms.

The Polyimide PCB manufacturer you choose to work with should be able to make different kinds of Polyimide PCBs, such as:

  • Third generation polyimides
  • Pure polyimides
  • Filled polyimides and;
  • Low-Flow Polyimides

Why Choose Polyimide PCB?

If you are looking for reasons to choose the Polyimide PCB, there are several of them. In addition to making PCBs flexible (bendable and foldable), the Polyimide PCB can also be picked for the following reasons:

Polyimide PCB is Flexible

This is the Unique Selling Point (USP) of the Polyimide PCB. The flexibility allows for the consumer electronics and other targeted applications to conform to different uses and folding options.

The flexibility also makes the Polyimide PCB ideal for use in the applications that require more of portability and frequency.

Besides, you can rely on it to improve the longevity of consumer electronics, considering that the circuit board helps these electronics to “absorb impacts.”

Polyimide PCB is Thermally Stable

The stability of the Polyimide PCB interfaces with the flexibility and the capability to withstand heat. This is evident in the compressive strength and elasticity of the circuit board; a feature that makes it impossible for the board to cower under excessive temperature.

Besides, the Polyimide PCB can function in environments that have up to 300-degree Celsius of temperature. In addition, it can significantly help in reducing the damages associated with excessive temperature, as “polyimides don’t change temperature quickly.”

Excellent Chemical-Resistance

It is one thing for the Polyimide PCB to be resistant to excessive temperature and another not to get damaged by chemicals.

On the contrary, it has an excellent chemical-resistance, which is derived from the chemical stability of the polyimides. It allows for the circuit board to have limited corrosion, as a result of overt exposure to “hostile chemicals.”

Tensile Strength is Tenable

Polyimide PCB’s elasticity allows for the board to withstand conditions, relating to extreme stress and excessive temperature.

However, one other aspect that boosts the operation is the tensile strength, which has to do with the Polyimide PCB’s capability to suit the different applications.

For example, the tensile strength allows for the Polyimide PCB to support higher maximum loads, as well as being reformed to “suit the available area.”

Wrapping Up

Some of the reasons to choose the Polyimide PCB include the improved durability, the tensile strength, the chemical-resistance and the flexibility. RayPCB helps you customize this circuit board to fit into the different applications, ranging from medical electronics, automotive electronics and a host of other consumer electronics, such as computer electronics.
