SMT PCB Assembly FAQ
1.What are the metal core PCB materials?
Including aluminum PCB, copper-based PCB, iron-based PCB
2.What are the advantages of metal core board?

heat dissipation. MCPCB is one of the PCB options with higher thermal conductivity.

Better strength and stability.

Dimensional stability.

Lighter weight and higher recyclability.

Longer service life.

3.What is a metal core PCB?

A metal core printed circuit board (MCPCB) is a printed circuit board that contains base metal materials. The core is designed to transfer heat away from components that generate a lot of heat.

4.How to Design RF Circuits
Develop high-level specifications for the design. Create device-level circuit descriptions using components such as transistors, inductors, and capacitors. Use circuit simulation to verify that the design meets all of its specifications. The physical layout of the design is achieved by assembling a predefined layout of all components. The equivalent circuit is then extracted from the layout.
5.What is RF PCB Design?

Radio frequency (RF) designs operate at high frequencies, and they require careful placement and routing to prevent signal integrity issues.

6.How to reduce LED PCB temperature
Besides adding lots of LED lights to reduce the temperature of the board, you can use another method. One of the most effective ways to reduce the temperature of LED PCBs is to use aluminum as the substrate.
7.What are the benefits of LED PCBs?
Reduce power consumption, longer life, more efficient, small size, no mercury, no radio frequency, environmental protection, and cost reduction.
8.What are the application areas of LED PCB?

Consumer Lighting, Consumer Electronics, Telecommunications, Transportation, Medical.

9.What is the substitute for "halogen"?
At present, most halogen-free PCBs are mainly replaced by phosphorus and phosphorus nitrogen
10.What are the properties of halogen-free PCB?

Insulation: Since the halogen is replaced by P or N, the polarity of the epoxy molecular bonds is reduced, which improves the insulation resistance and breakdown voltage.

Water absorption: Due to the relatively low electrons of N and P in the nitrogen-phosphorus-oxygen reduction resin, the probability of forming hydrogen bonds with hydrogen atoms in water is lower than that of halogens. The water absorption rate of halogen-free PCB is lower than that of conventional boards, which affects reliability to a certain extent.

Thermal stability: The nitrogen and phosphorus content in halogen-free PCB is higher than that of ordinary board, so monomer molecular weight and Tg value increase.

11.What is a halogen-free PCB?
According to JPCA (Japan Circuit Association)-ES-01-2003 standard: CCL with chlorine (Cl) and bromine (Br) content less than 0.09% Wt (weight ratio), respectively, is defined as halogen-free CCL (while CI+Br Total ≤0.15% [1500PPM]). Halogen-free PCBs are made of halogen-free copper clad laminates.
12.What are halogen-free materials?
Halogen-free materials are those that do not contain one group of halogen elements (fluorine, chlorine, bromine, iodine and astat).
