PCB是Printed Circuit Board(印刷电路板)的缩写,是电子设备中不可或缺的部件,用于支持和连接电子元器件。它广泛应用于各种电子产品中,例如手机、电脑、电视、汽车电子设备等。 PCB的基本结构 1.基材(Substrate) • 常见材料:玻璃纤维增强的环氧树脂(FR4)或酚醛树脂。 • 功能:提供机械支撑,使元件能够固定其上。
PCB生产主要包括印刷、电镀、蚀刻等过程；而Substrate生产则需要进行光刻、蚀刻等更先进的制程，要求更高的...
Problem to be solved: to provide a printed circuit board substrate capable of forming a fine conductive pattern while maintaining the adhesion between the conductive layer and the base film, a method of manufacturing a resin substrate and a method of manufacturing a printed circuit board. The ...

In the below illustration, you can see the stack-up of a single-layered printed circuit board. Now we are ready to briefly review each of the layers of the stack-up: 1. FR4 (Substrate) PCB substrate can be FR4, metal, or ceramic. FR4 is mainly used and is a reinforced epoxy laminat...
Depending upon requirement, PCBs can be single-sided bond (SSB, that is, one copper layer), double-sided bond (DSB, that is, two copper layers on both sides of one substrate layer), or multi-layer bond (MLB, that is, inner and outer layers of copper, alternating with layers of substr...
我的理解，substrate一般指的承载半导体的基板，把切割后的晶圆(Die)放置到substrate上进行封装，出来就是...
Bare plates (no parts on the board) are also often referred to as printed circuit boards Printed, Wiring, Board (PWB). The substrate of the board itself is made of insulation, heat insulation and material which is not easily bent. The fine lines can be seen on the surface of the ...
Printed circuit board has been developed for more than 100 years. The design of printed circuit board is mainly electronic layout design.
