What should I pay attention to when storing board-to-board connectors?

Insulation inspection rules for board-to-board connectors: the same type of insulating material produced by qualified suppliers, with stable product performance (returned without quality problems within one year), and sampling inspections every 5 tons.

For new insulating materials from qualified suppliers or insulating materials or samples from sub-supplied suppliers, samples should be sampled for type testing. The next five supplies are all subject to random inspection. After passing the test, they can be transferred to separate batch inspections. If the insulation material is found to be unqualified once, it shall be sampled according to the first batch of supply regulations. Each batch of insulating material must be accompanied by the supplier's material warranty or test report.

Sampling method: take 2 bags or more per batch. The inspectable items are tensile strength, elongation at break, dielectric strength, volume resistivity, volume resistivity at 80°C, oxygen index and density.

For the performance that cannot be tested, it shall be checked and accepted according to the manufacturer's test report or quality assurance certificate. The packaging insulation materials are packed in plastic film bags and external PP braid/kraft paper composites. The net weight of each bag is 25±0.2kg, but no negative deviation per ton is allowed.

Board-to-board connector insulation material packaging must be marked: manufacturer name, material model and name, production date, net weight and product qualification certificate and other signs. When the electronic wire connector insulation material enters the factory, it should be accompanied by the manufacturer's quality assurance certificate or quality inspection report. When supplying, the manufacturer must attach the type test report of the statutory inspection department. When supplying normally, the manufacturer must provide the type test report of the statutory inspection department of that year every two years.

The insulating material of the transport board-to-board wire connector should not be exposed to sunlight or rain, and the packaging should not be damaged.

The insulation material of the storage board-to-board wire connector should be stored in a clean, cool, dry and ventilated warehouse. The storage period is 12 months from the production date
