How to optimize the process of Shenzhen PCBA processing technology
1. First, provide a test plan according to the customer's PCBA circuit board design and manufacturing process, establish test points on the PCB circuit board or perform general functional tests, and use a professional test rack (we can make it for customers) to detect the circuit board path, Noise and stability, to ensure the quality of the customer's PCBA manufacturing process. After completing the sample stage, our engineers will strictly conduct functional and stability tests on the PCBA, such as on-off, noise, aluminum foil, drop, waterproof, etc., to form a performance test report. Arrange a small batch production plan through the final PCBA sample confirmation of the customer.

2. DFM report, in the manufacturing process, there may be problems in manufacturing due to design reasons, and the quality is difficult to meet the standards. The engineer will analyze the structure of the PCB circuit board in a targeted manner, put forward suggestions for improvement, and optimize the layout of the PCB circuit and components, which has tended to conform to the manufacturing process and improve the quality and stability. According to customer requirements, we can provide the corresponding DFM report, which is covered in the PCBA proposal.

3. Suggestions on the optimization of the processing technology of the components, the customer’s bill of materials BOM table, in the actual procurement process, there may be practical problems such as supplier shortages, production suspension, etc., and there may also be components that cannot meet the requirements of SMD patch and DIP plug-in process, Manufacturing engineers will make targeted optimization suggestions and alternative material solutions to ensure the maximum consistency of materials in the range of technical parameters without affecting the functional realization of the entire PCBA circuit board. At the same time, the timely supply of materials is guaranteed.

4. According to the customer's product prototype design, carry out ODM project development, carry out the feasibility analysis of the product's technical functions, underlying applications, and molds; make test plans and production plans; submit a proposal, including the overall project schedule and details Information on implementation plan, cycle, cost and cost estimation;

1. Hardware development: circuit diagram design, PCB circuit and shape design, sample processing, etc.

2. Software development: design customer UI, driver debugging, application layer development and debugging;

3. Mold development: build product outline drawings through CAD and 3Dworks, sample and debug;

4. Sample stage: Carry out samples, carry out functional and stability tests

5. Small batch stage: The customer conducts PCBA acceptance test (UAT), uses the functions in actual use, and applies feedback to make regression modifications, which tends to be perfect;

6. Establish mass production; organize the final version of technical documentation. Save the original information. Prepare the file.

5. Material control. In the PCBA electronic product processing and manufacturing process, material control is particularly important, which directly determines the potential risks of the entire processing process and avoids the cost of mass rework. Baiqiancheng has a dedicated material inspection post to check the customer's BOM list in detail, and use special instruments and test racks to test the materials to ensure 100% pass. The key to the appearance, shape, oxidation degree, and brand newness of the incoming materials Links are also included in the scope of inspection.
The relevant personnel will countersign the inspection documents that meet the ISO standards to ensure the traceability of the problem. PCBA material control, has a wealth of experience in component procurement, and has a 10-year cooperative relationship with many brand suppliers. The company gives full play to its competitive advantages in scale procurement and quality control, and signs long-term cooperation agreements with many domestic and foreign electronic component manufacturers to ensure the quality of raw material sources and stable supply, and maintain IC, resistors, capacitors, inductors, The advantages of purchasing basic electronic components such as diodes and triodes ensure the quality of PCBmanufacturing.
