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.
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.
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.
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.
What are the application areas of LED PCB?
Consumer Lighting, Consumer Electronics, Telecommunications, Transportation, Medical.
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-phos
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
Why is PCB impedance important?
Impedance affects how signals travel through the board, how power is transferred between components, and how signals penetrate into unwanted areas of the PCB.
What is an Impedance Control PCB?
What is Controlled Impedance? Controlled impedance is the characteristic impedance of the transmission line formed by the PCB traces and their associated reference planes.
What are the benefits of using PCB gold fingers?
Excellent electrical conductivity due to direct board connection and more gold thickness, strong wear resistance allows the PCB to be plugged and unplugged thousands of times, and the PCB pads use a hard gold plating process with good oxidation resistance
What is the appearance inspection standard of PCB gold finger?
Raised corners, nicks, scratches, sink (spots) and tin stains, oxidation, exposed copper or exposed nickel, spot copper shavings, test pin spots.
