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 a halogen-free PCB board
Apr 10,2023
A halogen-free printed circuit board (PCB) is a type of circuit board that does not contain any halogenated flame retardant additives in its construction. Halogenated flame retardants, such as brominated and chlorinated compounds, have been traditionally used in the manufacturing of electronic components to reduce the risk of fire. However, when these materials are burned or disposed of improperly...

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...

What's Multi-layer PCBs and advantages?
Apr 15,2023
Multi-layer PCBs are advanced circuit board designs that stack multiple circuit layers on top of each other, separated by insulating layers. Compared to single or double-sided printed circuit boards, multi-layer PCBs offer higher integration, better signal integrity, and smaller form factors, making them an essential component of modern electronic products. The design of multi-layer PCBs requires ...

BGA PCBs: The Future of High-Density Circuitry
Apr 17,2023
BGA stands for "Ball Grid Array," and PCB stands for "Printed Circuit Board." A BGA PCB is a type of circuit board that uses ball grid array technology for the attachment of integrated circuits (ICs) and other components. In a BGA PCB, the ICs are mounted on the surface of the board, and the electrical connections are made by tiny balls of solder that are attached to the bottom of the ICs. These b...

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...
