Factors affecting the quality of electronic board components

Abstract: Quality control is an important manifestation of a company's competitiveness and a necessary guarantee for long-term vitality. The level of product quality is not only constrained by the internal conditions of the company, but also stimulated and constrained by the external environment; not only is it affected by material factors, but also affected by factors such as policy, society, nature, and economy. Here are five important factors that affect product quality.

The five major factors affecting product quality:

The five major factors affecting product quality are: machine, material method, operator, and environmental factors. Among them, the causal diagram is a chart for a defect or failure finding reason. We can use the causal chart to find the root cause of the above five factors.

One of the sources of variation: machine ◆ tool sharpness of metal cutting machine tools, change of supply air pressure of pneumatic components (equipment) ◆ change of machine accuracy, source of variation of equipment failure, second source: material ◆ change of supplier, part of material, Change ◆Change in material size ◇Change in mechanical or electrical properties of material ◆Third source of variation in batches of material : Method ◇Change in production process 变更Change in operating method 工具Change in tool and fixture ◇Machine or operation parameter setting error

The fourth source of variation: operator â—† operator's proficiency, operator's habituality, â—† operator's working standard, operator's physical strength and emotion â—† operator's work environment
Five sources of variation: Environment â—† Stability of power supply, stability of water quality â—† Temperature, humidity, air quality â—† Adequate lighting, cleaning of the workplace, etc. Overall view of the above five points, how electronics manufacturers can improve production processes Product quality?

Machine: equipment playground specification, maintenance specification, instrument verification;

Materials: Supplier assessment and audit, IQC inspection;

Method: Job Instructions, IPQC Inspection Operators: Skills Training, Assessment of Qualified Workplace Environment: Workplace Temperature and Humidity Control, UPS Power Supply, Particle Surveillance in Air, Anti-Static Facilities, etc. Xiamen Yingruifeng Electronics Implements Strict Quality in Production Process To control, our quality concept: quality management, product defects, customers more satisfied. From quality research and development, procurement, manufacturing, and after-sales service, quality is our usual requirement. For its consistent quality of Seiko, it adopts refined manufacturing processes and strictly controls quality to ensure that every product has the quality of Seiko.

First, incoming quality control:

1. Compile the testing standards for various components and components such as RC, diodes, transistors, cassette capacitors, trip coils, transformers, transformers, PCB boards, etc.

2, equipped with suitable components and inspection equipment: such as transistor tester, pressure tester, LCR digital bridge, DC power supply, residual current protection, stereo microscope, etc.;

3. Each batch of incoming materials shall be strictly inspected in accordance with relevant standards, so that problems can be discovered in a timely manner and prohibit the inflow of unqualified materials into the production process.

Second, process quality control:

1. Prepare PCBA inspection standards and customer special product inspection standards;

2. The verification of each batch of 2PCS sample before production will be carried out in batches and the operator will be able to check the work according to the sample.

3. Compiled the main operating instructions for the production process, allowing the operator to understand the operation method more intuitively;

4. The squad leader and IPQC regularly confirm the products produced by the operator;

5. Equipped with test fixtures and inspection equipment suitable for production inspection of various models to ensure that product monitoring meets customer requirements;

6, the process set up a full inspection process to ensure that 100% of the products produced after passing inspection;

7. Before shipment, OQC will carry out sampling inspection again according to the standard before shipment.
