Introduction to board-to-board connectors for cell phones What do I need to pay attention to when storing board-to-board connectors?

1. Introduction to mobile phone board-to-board connectors: Currently, the spacing is mainly 0.4 mm,... Design, development and mass production of connectors such as Socket, card and BTB. Regarding board-to-board connectors, the development trend of board-to-board connectors in mobile phones is that the pin spacing and height are getting smaller and smaller. At present, it is mainly 0.4 mmpitch, and will gradually develop to 0.35 mm or even smaller. Lower height and shielding effect are required in the future. At the same time, the height of the BTB (board-to-board connector) is gradually reduced to 0.9 mm.

2. What should we pay attention to when storing board-to-board connectors? Insulation inspection rules for board-to-board connectors: insulating materials of the same type produced by qualified suppliers have stable product performance (returned without quality problems within one year), and random inspection will be conducted every 5 tons. For the new insulating materials of qualified suppliers or the insulating materials or samples of secondary suppliers, the type test shall be carried out by sampling, and the subsequent five supplies shall be subject to random inspection. After passing the test, it can be converted to random inspection in other batches. If insulating materials are found to be unqualified once during sampling, sampling shall be carried out according to the first batch of supply regulations. Each batch of insulating materials must be accompanied by a warranty letter or test report of the supplier's materials. Sampling method: Take 2 bags or more per batch. Testable items are tensile strength, elongation at break, dielectric strength, volume resistivity, 80 °C volume resistivity, oxygen index and density. The performance that cannot be tested shall be accepted according to the manufacturer's test report or warranty. The packaging insulation material is packaged with plastic film bag inside and PP braided fabric/kraft paper composite outside. The net weight of each bag is 25 ± 0. 2 kg, but no negative deviation is allowed per ton. The packaging of board-to-board connector insulation material must indicate: manufacturer name, material model and name, production date, net weight, product certificate and other marks. When the insulation material of electronic wire connector enters the factory, it should be accompanied by the manufacturer's quality guarantee or quality inspection report. When supplying goods, the manufacturer must attach the type test report of the statutory inspection department. During normal supply, the manufacturer must provide the type test report of the statutory inspection department of that year every two years. The insulation material of the transport board-to-board wire connector should not be exposed to sun and rain, and the packaging should not be damaged. Storage board-to-board wire connector insulation material should be stored in a clean, cool, dry and ventilated warehouse. The shelf life is 12 months from the date of manufacture
