PCBA processing notes

There are several key factors that need to be paid attention to during PCBA processing. Here are some major considerations:

Keep the operating environment clean and tidy: Whether it is the SMT patch production line or the DIP plug-in workbench, it must be kept clean and tidy. Any gray and furry items, food, etc. are not allowed, especially smoking.

Component selection: Choosing appropriate components is an important guarantee for ensuring the quality of the circuit board. When selecting components, you need to pay attention to the brand, model, package and parameters of the components to ensure the quality and stability of the components.

Design of PCB circuit board: The design of PCB circuit board needs to consider the size, layout, circuit direction and connection method of components. Certain layout rules need to be followed during design to avoid interference between components and ensure the stability and reliability of the circuit board.

Anti-static: During the PCB circuit board design and manufacturing process, attention needs to be paid to preventing static electricity interference. During operation, anti-static measures such as anti-static gloves and anti-static mats should be used to avoid damaging components.

Welding quality: Welding quality directly affects the performance and reliability of PCBA. It is necessary to ensure that the solder joints welded are of moderate size, smooth and flat, without holes, cracks, etc. At the same time, problems such as weak welding, false welding, and false welding should be avoided.

Operating specifications: During the PCBA processing process, operating specifications must be followed and the process must be strictly followed. Including the selection of solder, welding temperature, time, cooling after welding, etc., must comply with the specification requirements.

Quality inspection: Quality inspection is an important part of ensuring the quality of PCBA processing. The finished PCBA must be regularly inspected for appearance, electrical performance testing, reliability testing, etc. to ensure product quality.

Safety management: Safety management is equally important during PCBA processing. It is necessary to formulate strict safety rules and regulations and provide safety education and training to staff to ensure the safety of the working environment.

Environmental control: Environmental control is also very critical to the PCBA processing process. The temperature, humidity and cleanliness of the working environment must be maintained within appropriate ranges to ensure processing quality and normal operation of equipment.

Document management: Establish a complete document management system, including process flow diagrams, inspection records, equipment maintenance records, etc., to facilitate traceability and quality control of the processing process.
