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...

Classification of the PCB high-frequency boards
Mar 30,2023
With the rapid development of science and technology, more and more equipment is designed for microwave frequency band (> 1GHz) or even millimeter wave field (30 ghz) applications, which also means that the frequency is getting higher and higher for the circuit board substrate, for example, the substrate material needs to have excellent electrical performance and good chemical stability. With t...

What is the difference between four layers PCB boards and two layers boards？
Mar 29,2023
The four-layer PCB board is pressed on the basis of the double-sided PCB (two layer boards). Below is an outline that will help you understand and know the difference between 2 Layer printed circuit boards and 4 Layer printed circuit boards. 2 Layer Printed Circuit Board vs. 4 Layer Printed Circuit board In PCBs, layers are very important. Layers are copper layers on the circuit board. A circuit b...

Do you know quick turn PCBs?
Mar 29,2023
Quick turn PCB refers to the process of manufacturing printed circuit boards (PCBs) with a very short turnaround time. In the past, PCB fabrication was a time-consuming process that could take weeks or even months to complete. However, with the advent of new technologies and processes, it's now possible to produce PCBs in just a few days or even hours. Quick turn PCBs are typically used in applica...

What you need to know before choosing a PCB manufacturer？
Mar 27,2023
With so many PCB manufacturers on the market, choosing the most suitable PCB manufacturer can be a challenge. Some PCB manufacturers serve well for individual inventors and small businesses, while others are more suited to the choice of larger companies. For whatever reason, the PCB circuit board design, these precautions should be kept in mind before selecting a PCB manufacturer. Making the best ...
