Printed Circuit Board is an extremely important part of the electronics sector, typically utilized in a variety of electrical equipment and tools. Among the core homes is temperature level resistance. So What maximum temperature level can the PCB board endure? Allow’s take a better look.

To start with, PCB temperature resistance performance.

The temperature level resistance efficiency of the Printed Circuit Board suggests that in a high-temperature environment, the board will not show up embrittlement, cracking, contortion, and various other sensations. As a result, the temperature level resistance of the board is very crucial.

Under regular conditions, The temperature resistance performance of PCB handling is affected by lots of variables such as product, making procedure, circuit structure and more. Amongst them, the product is the primary aspect influencing the temperature level resistance of the PCB board.

Secondly, the temperature level resistance efficiency of frequently utilized products of PCB board.

1. FR-4 material

FR-4 is a glass fiber-reinforced epoxy product commonly used in PCB manufacturing. The temperature resistance of FR-4 product is normally concerning 130 ° C, and surpassing this temperature level will trigger deformation or failure of the board.

Because of the advantages of low manufacturing expense, high cost efficiency, and good processability, FR-4 products are additionally widely made use of in the high-end electric industry and have been tested by lasting method. Nevertheless, for high-temperature applications, the temperature resistance of FR-4 materials is not enough.

2. High-temperature FR-4 material

High-temperature FR-4 is a glass fiber-reinforced epoxy product particularly developed for high-temperature atmospheres. Compared to FR-4 materials, high-temperature FR-4 products have better temperature resistance and can endure temperatures of approximately 150 ° C or more. Although the manufacturing price of high-temperature FR-4 is high, its dependability in high-temperature atmospheres is far better than the basic FR-4, so it has been widely utilized in the premium electric devices sector.

3. Polyimide material

Polyimide is a sort of high-performance insulating material, with superb high-temperature resistance, chemical corrosion resistance, electro-magnetic wave disturbance, and various other features. It is one of one of the most superb high-temperature resistance materials on the marketplace, which can hold up against high temperatures above 380 ° C, and really couple of brand names of polyimide products can also endure heats over 500 ° C.

At present, polyimide materials are mostly used in aerospace, military, and high-precision temperature dimension devices. Although polyimide materials are expensive, their integrity at high temperatures is unequaled by various other materials.

To evaluate, the maximum temperature that a PCB can stand up to can exceed 500 ° C, contingent upon the particular product make-up of the board. For typical electric devices and instrumentation, FR-4 or high-temperature FR-4 products are normally employed, as they are enough for a lot of applications. Nevertheless, certain specialized, such as aerospace and defense, require using innovative materials like polyimide. Consequently, when selecting a PCB product, it is critical to choose a type and temperature level score that straightens with the specific use situation, consequently making certain’s reliability.
