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 ...

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 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...

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, ...

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 ...

What is SMT assembly?
Apr 04,2023
What is SMT mount assembly? Surface Mount Technology (SMT) is a method of electronic component assembly in which components are mounted directly onto the surface of a printed circuit board (PCB). SMT mount assembly is the process of assembling electronic components using this technology. In SMT mount assembly, electronic components are typically much smaller than the through-hole components used i...

Multi-layer PCB stack design
Apr 04,2023
Multilayer PCB or multilayer printed circuit boards are circuit boards composed of two or more conductive layers (copper layers). The copper layer is pressed together by the resin layer (prepreg). Due to the complexity of the multilayer PCB manufacturing process, low production volume, and difficulty in rework, their prices are relatively higher than a single layer and double-sided PCB. Multi-laye...
