Thick copper PCB

Tag: copper high-power Better

Thick copper PCB is widely used in power electronic equipment and power supply systems. The growth trend of the PCB industry is that the finished copper weight exceeds 4oz (140μm), while the copper weight of the standard PCB is usually 1oz (35μm) or 2oz (0μm).

The extra copper of PCB allows the printed circuit board to conduct more current and achieve excellent heat distribution, which can realize complicated functions in a limited space. Other advantages include improving the mechanical strength of the connector position, the ability to make the smaller sizes of products by combining multiple weights on the same circuit layer, and the ability to use exotic materials with maximum capacity and minimize the risk of circuit failure.

Advantages of thick copper PCB:

1) Greatly increase the current capacity

2) Higher resistance to thermal strain

3) Better heat dissipation

4) Increase the mechanical strength of the connector and PTH hole

5) Reduce product size

Application of thick copper PCB:

With the increase of high-power products, the demand for thick copper PCBs has also greatly increased. Nowadays, PCB manufacturers pay more attention to the use of copper plates to solve the thermal efficiency problem of high-power electronic equipment.

Thick copper PCBs are mostly high-current substrates. The high-current PCBs are mainly used for power modules and automotive electronic parts.

High TG PCB

Tag: TG value heat resistance chemical resistance stability

What is High TG PCB

"TG" refers to the glass transition temperature of the printed circuit board (PCB); it is the temperature point at which the PCB material begins to change. If the operating temperature exceeds the specified TG value, the circuit board will change from a solid-state to a rubber state and adversely affect the performance of the PCB.

Generally, standard PCBs are made of materials with a TG value of 140°C and can withstand an operating temperature of 110°C. These PCB materials will soften, melt, or even deform at high temperatures, which will reduce the mechanical and electrical properties of the entire product. Therefore, this ordinary PCB may not be suitable for the extreme temperature conditions common in applications such as industrial electronics, automobiles, and high-temperature electronics.

High TG PCB means that the TG value of the PCB material is greater than 170°C. The higher the TG value, the better the heat resistance, chemical resistance, and stability of the PCB.

Features of TG PCB

Generally, the TG value of the PCB should be at least 10-20°C higher than the working temperature of the product. If the TG value is 130°C, the working temperature should be lower than 110°C; if the TG value is 170°C, the working temperature should be lower than 150°C. High heat is very scary for unprotected PCBs. The dielectric and conductors will be damaged, and mechanical stress will be generated due to the difference in thermal expansion rate, which will lead to unstable performance or even complete failure.

If you are using a high-power density design or need a lead-free PCB assembly manufacturing process, then high TG PCB may be the only partner in PCB manufacturing. The more heat you need to handle, the greater the impact on PCB design. Adding radiators and fans may increase the weight, size, and cost of the product. Lower power density power may limit the effectiveness of the overall result. In this case, high TG materials may be the right choice to become part of the overall thermal control solution.

Materials of High TG PCB

FR-4 is a NEMA grade designation for glass-reinforced epoxy laminate material. PCB made of FR-4 material has higher heat resistance than standard PCB. Generally, the TG value of FR-4 material is 120-180°C. If your requirement for TG is at least 200°C, you can also choose ceramic, polyimide, or PTFE materials.

NextPCB is an experienced PCB prototype and PCB assembly manufacturer, providing high TG PCB made of FR-4 with high heat resistance as substrate material. Many customers from the military, defense, electric power, nuclear energy, electric power, automotive, and other industries regard NextPCB as an important partner for their PCB design and manufacturing.

High-frequency PCB

Tag: High-frequency PCB one-stop PCB manufacturer fast speed

What is High-Frequency PCB

High-frequency PCBs generally provide a frequency range of 500MHz to 2 GHz, which can meet the needs of high-speed PCB design, microwave, radiofrequency and mobile applications. When the frequency is higher than 1 GHz, we can define it as high frequency.

Today, the complexity of electronic components and switches keeps increasing, and a faster signal flow is required than usual. Therefore, a higher transmission frequency is required. When integrating special signal requirements into electronic components and products, high-frequency PCB has many advantages, such as high efficiency, fast speed, low attenuation, and constant dielectric constant.

High-frequency PCB characteristics

1. DK should be small and stable, most of the time the smaller the better, the high DK may cause signal transmission delay.

2. DF should be small, whose size mainly affects the quality of signal transmission. The smaller the DF, the less the signal loss.

3. The thermal expansion coefficient should be the same as the copper foil as much as possible because the difference will cause the copper foil to separate in the cold and heat changes.

4. The water absorption rate must be low. In a humid environment, a high water absorption rate will affect DK and DF.

5. Heat resistance, chemical resistance, impact resistance, and peel resistance must be good.

High-frequency PCB - special materials

Special materials are needed to realize the high frequency provided by this type of printed circuit board, Because any change of their permittivity may affect the impedance of the PCBs. Many PCB designers choose Rogers dielectric material because it has lower dielectric loss, lower signal loss, lower circuit manufacturing costs, and is more suitable for rapid turnaround prototype applications among other materials.

NextPCB is an experienced one-stop PCB manufacturer, providing reliable, high-frequency PCB manufacturing services with excellent performance.
