What is the PCB?

by:Rigao      2020-04-04
PCB =印刷电路板; Chinese name called printed circuit board, also called printed circuit board, is an important electronic components, electronic components to support the body, is the carrier of electronic electrical connection. Since it is made of electronic printing, therefore is called 'printed circuit board. What is the PCBA? PCBA =组装PCB。 All kinds of electronic devices by surface encapsulation process on the circuit board assembly. Next is box assembly, the assembled PCB with shell together, such as formation of finished products. On the empty plate after SMT parts, that is to say, PCB again after DIP plug-in the entire process, referred to as 'PCBA. This is A commonly used one kind of writing, and in Europe and the United States is the standard writing PCB 'A, is the point. PCBA, it is a piece of PCB. What is the difference between the PCB and PCBA? PCB is referring to the PCB and PCBA refers to the circuit board plug-in assembly, SMT process. One is the finished board is a bare PCB board ( 印刷电路板) Known as the 'printed circuit board', made of glass epoxy resin materials, according to the signal layers divided into 4, 6, 8 layer board, with 4, 6, the most common layer board. Chips such as SMT components on the PCB. PCBA may be understood as the finished circuit boards, PCB process is done to calculate on the PCBA. PCBA = Cirruit印刷板+组装。 On the empty plate after SMT parts, that is to say, PCB again after DIP plug-in the entire process, referred to as 'PCBA. PCB( 印刷Circuie板) Short for printed circuit board, usually put on the insulation material, according to the book design, printed circuit, printed components or a combination of the two conductive graphics called printed circuit. On the insulating substrate to provide components of electrical connection between conducting graphics, called printed circuit. Thus the printed circuit product called printed circuit board or printed circuit, also called printed circuit board or printed circuit board. Standard PCB top no spare parts, and is often referred to as the 'Printed circuit Board Printed Wiring Board ( PWB) ”。
