Storage instructions for board to board connectors:

Insulation inspection rules for electronic connectors: Insulating materials of the same model produced by qualified suppliers with stable product performance (returned without quality problems within one year) shall be sampled every 5 tons.

For new insulation materials from qualified suppliers or insulation materials or samples from suppliers who supply for the first time, type tests should be conducted on the first sampling, and random inspections should be conducted on the following five supplies. After passing the inspection, it can be switched to batch sampling. If insulation materials are found to be unqualified in one sampling, they shall be sampled according to the regulations for the first batch of supply. 3.1.4 Each batch of insulation materials must be accompanied by a quality assurance certificate or testing report from the supplier's materials.

Sampling method: Take 2 bags or more from each batch. The detectable items include tensile strength, elongation at break, dielectric strength, volume resistivity, 80 ℃ volume resistivity, oxygen index, and density.
