The inspection of connectors for power semiconductor devices is divided into two categories: quality consistency inspection and identification inspection. 6.1
Quality Consistency Inspection
6.1.1 Group A Inspection (Batch by Batch)
Each batch of connectors must be inspected according to the items specified in Table 3. 3
Inspection items

Sampling plan AQI, inspection level II
Note: See Appendix A for the specific sampling plan for AQL. For batch inspection, if the initial submission is unqualified, it can be resubmitted for re-inspection according to the method of strict first-level inspection, but it can only be submitted once.
Group C inspection (cycle)
The connectors produced in finalized form must be inspected every six months according to the items specified in Table 4. 6.2

Sampling plan
The purpose of identification test is to determine whether the manufacturer is capable of producing products that meet the requirements of the standard. When the design, process, material changes or the production is resumed after suspension, the identification test should be carried out. For connectors that have been finalized and are produced in normal batches, at least one batch of identification tests should be carried out every three years. The items of identification test shall be carried out according to the items specified in 6.1 and Table 5. 5

Sampling plan
Note: In the sampling plan, n and c are the number of samples and qualified judgment integers respectively. If the first sampling test fails, it can be inspected again by adding sampling according to the cumulative method, but only once. 7
Packaging, transportation, storage, labeling
Connectors should be packaged after they have passed the inspection and obtained the certificate of conformity. When packaging, first put the connectors into the plastic bag and seal it, then put it into the paper box or wooden box and nail it.
7.2 Transportation
During transportation, connectors should be strictly prevented from violent vibration and collision to avoid damage. 7.3 Purchase and storage
Connectors should be stored in a dry, ventilated place without acid or acid gas corrosion. 7.4 Labeling
The following marks should be marked in a conspicuous place outside the packaging bag, packaging carton or packaging wooden box: a. Product name;
b. Product model and specifications:
c. Manufacturer name;
d. Date of manufacture or batch number
The purchaser shall conduct acceptance inspection within three months after receiving the connector. If any problem is found, it shall be promptly reported to the supplier for joint processing by both parties. 4
