When the buyer asks whether it is a full inspection, the answer should be stratified by project: some projects must be done one by one, while some doing them all will only delay the delivery time and produce no actual benefits. If the inspection is on the wrong level, the quotation and delivery rhythm will be disrupted.
The full inspection is for items that can be completed within a few minutes.
Appearance and labeling, normal temperature light emitting and light receiving power, DDM reading, code writing verification, and power-on connection, these projects only take minutes, and only by doing them one by one can we prevent missing parts and individual defects in the assembly. Network cards and expansion cards also need to run port traversal card by card. to100M single-mode dual-fiber one optical and one electrical fiber optic transceiver and 14-slot box transceiver rackFor example, the item-by-item contents of the complete machine and the rack are different, and the meaning of full inspection is also different. When placing an order, it is recommended to write down which level the inspection is to.
There are three types of reasons why projects can only be drawn in batches:
- Time consuming: High and low temperature retesting and aging are measured in hours. Doing them all will delay the delivery time.
- Band loss: Plug and unplug life and mechanical strength tests will consume samples
- Statistical: Eye diagrams and error codes rely on samples to infer batch distribution, and there is no place to record all measurements.
The sampling inspection caliber should be confirmed when placing the order.
The level of sampling determines the strength of the conclusions. The corresponding relationship between the batch size and sample size, the number of qualified judgments, and the stricter rules after non-conformity occur must be stated in the order. Subsequent disputes are mostly due to the blank caliber. If multiple consecutive batches are qualified, they can be dropped back to the normal level as agreed; when the same defect reoccurs, the sampling ratio should be doubled or even transferred to full inspection. For code-writing custom orders, because the code is bound to the peer device, it is recommended to verify it one by one;SFP Gigabit single mode dual fiber 10KM optical moduleFor this type of common gear, the combination of full inspection and temperature retest is more common.
In one sentence: the individual responsible for full inspection will not miss out, and the responsible batch for random inspection can be inferred. EB-LINK's factory records are reported in columns according to these two levels. The gear range and sampling caliber can be confirmed when placing an order. Call 0755-83179002.
