1.**Component selection and procurement**

　　Select appropriate components based on circuit design requirements,including ICs,resistors,capacitors,connectors,etc.,and manage the supply chain to ensure the quality and supply stability of components.

　　2.**SMT(Surface Mount Technology)and THT(Through Hole Technology)assembly**

　　Master surface mount technology and through-hole insertion technology,and be able to develop reasonable assembly processes based on PCB layout and component characteristics.

　　3.**Testing and Verification**

　　Having a complete testing plan,including functional testing,performance testing,reliability testing,etc.,to ensure that the quality and performance of PCBA meet the design requirements.

　　4.**Fault analysis and resolution**

　　When problems are discovered during testing or production,the ability to quickly identify the cause of the malfunction,propose solutions,and implement improvements.

　　5.**Software integration and debugging**

　　For PCBA containing embedded software,it also has the ability to integrate and debug software to ensure that the software and hardware work together properly.
