PCB printed circuit board/SMT Surface Mount Technology

◆ PCB(Printed Circuit Board)It is the basic component of electronic equipment, mainly used to support 

and connect electronic components. A conductive pattern is formed on the insulating substrate using printing 

to provide an electrical connection for electronic components.


◆ SMT(Surface Mount Technology)It is an electronic assembly technology that is mainly used to mount 

electronic components directly on the surface of a PCB. Compared with traditional pin-type assembly, SMT 

technology has higher density and higher performance, which can improve assembly efficiency and circuit density.


◆ Main differences:
1. Functions & Uses:
PCB:It is mainly used as a support and connection platform for electronic components.
SMT:It is an assembly technique used to mount electronic components on a PCB.
2. Process:

PCB:It involves circuit design, substrate making, pattern transfer, etching, drilling, electroplating, testing and 

other steps.

SMT:It involves the placement, welding, testing and other steps of components.
3Finished product form:
PCB:It is a semi-finished product, with only circuit graphics and no installed components.
SMT:It is a finished or semi-finished product with components attached to the PCB.

◆ SMT Technology typically applied to a PCB, involves a series of processes to mount electronic components onto the surface of a PCB to form a complete circuit board assembly (PCBA). By understanding the difference and connection between PCB and SMT, you can better grasp the key technologies and processes in the electronics manufacturing process.

Printed circuit board is an important electronic component, the support of electronic components, and the provider of electrical connection of electronic components. Since it is made using electronic printing, it is called a "printed" circuit board.

Steps to detect the authenticity of electronic materials:

◆ Discrete Component testing
◆ Failure Analysis(FA)
◆ Ageing test
◆ Programming Greplication
◆ Scanning electron microscopy
◆ ROHS Test
◆ Lead-free Testing(XRF)
◆ Roast
◆ Special Analysis and Test Report

◆ Visual Inspection
◆ Performance Testing
◆ X-RAY testing
◆ Cap Opening Detection
◆ Slice Test
◆ HCT Test
◆ Solderability Test
◆ Electrical Characterization Test
◆ Ultrasound Scan
