The main factors affecting the thermal conductivity of aluminium-based circuit boards
Apr 07,2023
The thermal conductivity of aluminium-based circuit boards can be affected by several factors, including: Composition:The composition of the aluminium-based circuit board can greatly impact its thermal conductivity. For example, the presence of impurities or alloying elements can reduce the thermal conductivity. Thickness: The thickness of the aluminium layer in the circuit board can also have an ...

Why are most printed circuit boards green?
Apr 07,2023
If you are asked what colour a printed circuit board is, I believe the first response is green. Printed circuit boards are basically made up of pads, vias, solder resist layers, silkscreen layers, copper traces, various components and other parts. Copper is a more active metal, in the air is easy to react with the oxygen in the air, in order to prevent copper vaporisation, will use a special ink, ...

What is the difference between FPC flexible boards and PCB rigid boards？
Apr 10,2023
Flexible printed circuit (FPC) boards and rigid printed circuit boards (PCBs) are two types of circuit boards used in electronic devices. The main difference between FPC and PCB is their flexibility and rigidity. FPC boards are made of a flexible material such as polyimide or polyester film, which allows the board to be bent, twisted, or folded to fit into tight spaces or conform to the shape of t...

Do you know ENIG Surface Finish for PCB?
Apr 20,2023
ENIG (Electroless Nickel Immersion Gold) is a surface finish used in the production of printed circuit boards (PCBs). It involves depositing a thin layer of nickel onto the copper pads and traces of the PCB, followed by a layer of immersion gold. (4 Layer ENIG PCB Board) The main advantage of ENIG is its flat surface, which makes it suitable for fine-pitch surface mount technology (SMT) components...

Precautions for purchasing HDI blind and buried hole circuit boards?
May 03,2023
As the current design of portable products is developing toward miniaturization and high density,the difficulty of PCB design is also increasing, which puts forward higher requirements for PcB processing technology. Most of the current portable products use the BGA package with a pitch of less than 0.65mm, and the design process of blind and buried holes is used. So what is a blind and buried hole...

Half Hole PCB
May 03,2023
What is a Half Hole PCB? Half-hole PCB means that one drill hole (drill, gong groove) is drilled, and then the second drill, shape process, and finally half of the metallized hole (groove) is reserved. Module PCBs are basically designed with half holes, mainly for the convenience of welding, small module area, and many functional requirements. The usual half hole is to design a hole on the edge of...

What is A High Frequency PCB?
May 06,2023
What is a high frequency PCB? High-frequency PCB refers to a special circuit board with high electromagnetic frequency. It is a circuit board produced by using part of the ordinary printed circuit board manufacturing method on the microwave substrate copper-clad laminate or by using a special processing method. Most of the time, these high-frequency PCBs have a frequency range between 500MHZ and 2...
