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 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...

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...

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...
