d-sub connector product application and soldering attention

The d-sub connector is the basic connector for industrial production and is used in several c-series control modules from ni. To a large extent, the difference between d-sub fittings depends only on the number of weaves in the connector. d-sub series has been expanded with new economical connectors. This new series of products to face the increasing need for only a small number of less frequent plugging and unplugging applications, such as television set-top boxes, control devices and meters, fci's economic development series of d-sub connectors are used to achieve a small number of cycles to plug down the application, such as television set-top boxes, control systems and power energy instrument panels; and this application of the market demand is increasingly high. The economic development of the circuit board direct soldering series products. d-sub connector is one of the first solutions, are the most diversified and widely used a type of key / export connector system software. d-sub connector soldering precautions (1) proposed to cover the copper foil should be wrapped in the inner mold before wrapping a layer of thermal insulation tape to avoid the core wire in the soldering of the copper foil or injection molding processing foreign models when the scalding blistering; (2) Covered copper foil is not allowed to have cracked or damaged; (3) If found that the copper foil is damaged, you can use the copper foil to seal the broken place, and then will make up for the copper foil and the original copper foil between the seams have to be thoroughly soldering welding with solder; (4) thoroughly wrapped copper foil, from all angles are not allowed to see the inner mold or the core wire is exposed; (5) Soldering welding need to pay attention to the core wire can not be burned. (6) Do not allow the solder into the gap between the inner mold and the connector and the solder penetrates into the inner mold of the thermal insulation paper.
