PCBA Tech - Demystifying the PCBA foundry processing process

Demystifying the PCBA foundry processing process

In the previous article, the editor introduced to you what PCBA foundry materials are, and at the same time, they have a simple classification. In order to better understand PCBA foundry materials, we will learn about PCBA generation materials today. The process of working with materials.

Process control is an indispensable part of the production process of processing PCBA foundry materials. It has a variety of processing methods, such as solder paste, patch glue, component loss, etc. for quota management, as well as art parameters, Process, personnel, equipment, materials, processing and testing, workshop environment and other factors to carry out standardized control. These operating methods and processing methods are very helpful to improve the overall quality of SMT chip processing and PCBA processing. In the process of controlling the processing, we can find and screen out the poorly processed products at the first time and take them off the assembly line, so that such unqualified products cannot enter the next processing link. An excellent processing manufacturer should strictly control product quality and put quality management first.

Let's give you a brief introduction to the process control.

1. Product batch management
The nonconforming product control procedures shall clearly stipulate the isolation, identification, recording, review and handling of nonconforming products. Usually SMT patch should not be repaired more than three times, and components should not be repaired more than twice.

2. Maintenance and maintenance of processing equipment.
The key equipment should be inspected regularly by full-time maintenance personnel, so that the equipment is always in good condition, the equipment status is tracked and monitored, problems are discovered in time, corrective and preventive measures are taken, and maintenance and repair are performed in a timely manner.

Three, the production environment
1. Water and electricity supply must meet processing standards and be stable;
2. Temperature, humidity, noise and cleanliness meet the requirements of PCBA processing;
3. Strict anti-static system is required during PCBA processing;
4. The entry and exit system, equipment operating procedures, and process discipline of the production workshop are strictly implemented in accordance with the requirements.

Four, production
The site is reasonably set up and the identification is correct; the warehouse materials and work-in-process are classified and stored, neatly stacked, and the ledger is consistent.

This is a brief process of controlling the PCBA OEM manufacturing process. There is no shortage of words such as "strict" and "tidy". The high-frequency use of these words means that the PCBA OEM manufacturing control is strict and High standards, but also hope that readers can have a preliminary understanding of its processing flow control.
