Customer acceptance process
In the delivery process of domestic connectors, customer acceptance is a key step to ensure that the products meet the requirements for use. Linkplex's cooperation experience with most industry customers indicates that a complete acceptance process usually includes the following steps:
Material confirmation
Before acceptance, the customer shall check the supply list, inspection report, qualification certificate and relevant technical documents to ensure that the supply batch and specification model are consistent with the order.
2. Appearance and Dimension Inspection
Check the connector for any defects such as scratches, cracks, or coating peeling.
●Use calipers, fixtures, and other tools for critical dimension measurements to ensure consistency with design standards.
Electrical performance test
●Through contact resistance, insulation resistance, withstand voltage and other tests, confirm that the connector meets the electrical performance requirements.
High-speed signal integrity tests are required for some products to verify their stability under high-frequency transmission.
4. Mechanical property testing
● Insertion/extraction life test: Confirm reliable contact after thousands of insertions and extractions.
Retention and extraction force testing: Ensure that the connector is neither loose nor difficult to assemble or maintain.
5. Environmental and Reliability Verification
● Conduct high and low temperature cycles, salt spray tests, humidity tests, etc., to verify the suitability of the connector in extreme environments.

●Through accelerated life testing, anticipate the stability of products in long-term applications in advance.

Second, matters needing attention for acceptance
1. The sampling ratio is reasonable.
When supplying in large quantities, scientific sampling methods should be used to avoid quality issues caused by missed inspections.
Unified standards
●Advise customers to confirm the reference testing standards (such as IEC, UL, or customer internal standards) with suppliers before acceptance, to ensure the comparability of test results.
Record and trace
A complete inspection record and confirmation slip are formed during the acceptance process, providing a basis for subsequent use and after-sales service.
Communication and Feedback

When problems are found during acceptance, it should be communicated with the supplier in a timely manner to avoid affecting the delivery progress due to information asymmetry.

The customer acceptance process for domestic connectors is not only a verification of the quality of the product itself, but also a test of the supplier's production management system. Linkplex, relying on strict quality management and a comprehensive certification system, can provide customers with high-stability and high-reliability connector products, helping customers to achieve long-term stable operation in various application scenarios.
