For one-stop PCB assembly services, many aspects are involved, such as PCB production, component procurement, printed circuit assembly, testing, etc. With higher requirements for lean manufacturing capabilities of electronic products, more higher manufacturing capacity requirements. The electronic assembly manufacturers are required to pay more attention to PCBA processing quality management. PCBFuture introduces you to the key points of PCBA electronic manufacturing quality management.
Key point 1: PCB production
There are many factors that determine the quality of PCB, among which substrate material, production control, and copper thickness are the most critical. When choosing a PCB factory, you should not only pay attention to its price, but also pay attention to these key quality points. The grades of substrate materials range from A to C, and the prices vary greatly. Complete quality management and professional technical services will have a greater impact on PCB quality.
Key point 2: Procurement of components
Ensure that the components come from the original brand, which is the key to the packaging process, which can prevent batch defects from the source. The electronic assembly manufacturer needs to set up incoming material inspection positions (IQC, Incoming Quality Control), check the consistency of incoming materials, and sample the appearance, component values, errors, etc. PCBA manufacturer also needs to continuously optimize its component supplier channels.
Key point three: surface mount process
In the SMT chip processing surface mount process, PCBA electronics manufacturing companies need to ensure the uniformity and consistency of solder paste printing, reasonable programming of SMT machines, and ensure high-precision IC and BGA placement yield. 100% AOI inspection and manufacturing process quality inspection (IPQC, In-Process Quality Control) is very necessary. At the same time, it is necessary to strengthen finished product inspection management.
Key point 4: PCBA test
Design engineers generally reserve test points on the PCB and provide corresponding test plans to PCBA processing electronics manufacturers. In ICT and FCT tests, the circuit voltage and current curves are analyzed, as well as the results of electronic product functional tests (possibly with some test frames) , and then the test plans are compared to establish the acceptance interval, which is also convenient for customers to continue to improve.
Key point five: management of people
For PCBA electronics manufacturing companies, high-end sophisticated equipment is only a small part of it, and the most important thing is human management. The more important is production management personnel formulate scientific production management procedures and supervise the implementation of each station.
In the fierce market competition, electronic manufacturing companies continue to optimize their internal power and refine their production management is the key to continuously adapting to the market. Manufacturing quality control and service will surely become the lifeline of competition.
