The outbreak in Malaysia continues, causing the local semiconductor industry to be hit. Severe epidemic has caused some chip factories to be closed. According to The Paper, the STMicroelectronics chip supplier in the Muar packaging plant in Malaysia with more than 3,000 employees, there are more than 20 employees sacrificed due to the epidemic, and hundreds of people have been infected, facing the...
Printed Circuit Board Introduction PCB ( printed circuit board ) is a key component in the electronics industry and it is also a basic component. PCB carries all the components to be PCBA and then becomes the core of every electronic products. This article will give you a general idea about PCB, show the PCB composition and some main aspects. What is PCB？ PCB（Printed circuit board）is...
Rigid PCB Manufacturing Process Flow 1. Cutting Cutting is the process of cutting the copper clad laminate into pieces that can be reprocessed in the production process line. (1) Unit: Unit refers to a single small board designed by PCB design engineers. (2) Set: Set refers to the unity formed by putting together multiple Units for reasons such as improving production efficiency and facilitating p...
Solder Mask Both sides of the PCB are copper layers. In PCB production, the final copper layer is a smooth and unprotected surface. Although the chemical properties of copper are not as active as aluminum, iron, magnesium, etc., pure copper is easily oxidized when there’s water and oxygen. Because of the presence of oxygen and water vapor in the air, the surface of the pure copper will oxidize ver...
What’s the difference between rigid PCB and flexible PCB? PCB usually refers to printed circuit board, which is called rigid PCB. PCB is generally made of FR4 substrate, also called rigid PCB, which can not be bent and flexed. PCB is generally used in some places that do not need to be bent and have a relatively hard strength, such as computer motherboards, cell phone motherboards, etc. FPC, in fa...
Multilayer Printed Circuit Board The manufacturing method of multi-layer circuit boards, generally to make the inner layer pattern plating first, and then make the single-sided or double-sided substrate by printing and etching, and incorporate it into the specified layer, and then heat, press and glue it, and then other produce process is same as the production of double layer panel. In terms of p...
Single layer PCB is also called as Single Sided PCB is a type of PCB, which comes with only one layer of conducting material on one side of the board, and the other side is used for incorporating different electronic components on the board. Single layer PCB starts important role in Printed Circuit Board field and it is still important in the electronic industry today. What are the advantages &...
