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 is the purpose of baking during PCB processing
Mar 20,2023
Why should PCB processing bake? Those engaged in PCB processing industry know that copper clad plate has a baking process in the process of processing into PCB circuit board, and the main purpose of PCB baking is to remove dampness Tide, remove the water gas contained or absorbed from the outside world, because some of the material used by PCB itself is easy to form water. Secondly, the purpose of...
