What should be paid attention to to improve the performance of the charging needle?

The charging needle is commonly known as a probe, which is mainly composed of a needle, a needle tube and a spring. It is mainly used to test the wiring situation of the PCB board, or used for online testing after plug-in, as well as for BGA packaging testing and chip testing. Of course, it should be noted that when testing the wiring of the PCB, a test mold needs to be made, and generally speaking, an OCB board can only be tested by one mold. However, in the ordinary test process, if you want to strengthen the various performances of the stable connector, the charging needle manufacturer should take the oxygen-enhancing test. Next, based on the relevant experience of Shenzhen Senbo Technology Co., Ltd. Learn what changes can be made to improve the performance of your product.

The needle head of the charging needle can ensure a very low and stable contact resistance through the design concept of the bevel structure, and this design concept can also absolutely guarantee the stable conduction performance of the product. In addition, the needle also uses a perforated structure. This design can make the length of the matching spring completely exceed the length of the needle tube, so that even in the case of very limited space, stable elasticity and stroke can be obtained. However, it should be noted that the needle should try to avoid the flat-bottom design method, because this design method will prevent the charging needle needle from being in normal contact with the spring thimble needle tube, so that the current cannot pass through the needle tube, which will lead to excessive resistance. , causing the current of electronic products to be unstable.

The next step is the design of the charging needle tube. Shenzhen Senbo Technology Co., Ltd. will guide its own charging needle manufacturers to set the overall structure of the charging needle according to the customer's structural space for charging and the function and life of the product. . According to the product catalog of Shenzhen Senbo Technology Co., Ltd., it is not difficult to find that they will fully consider the convenience of fixing the product on the PCB and the welding depth, and they will also provide special-shaped or folding for the connection of the battery. The needle tube with a 90° bend is available for customers to choose, so as to choose the most suitable charging needle for the customer.

In any case, if you want to maintain the precise size of the charging needle and meet the requirements of more customers for products, you must put forward the highest standards for the material or design of the charging needle. Generally speaking, stainless steel SUS304 or The piano steel wire is used as the material of the spring, because this material can ensure the toughness of the spring and thus increase the service life of the charging needle. These are the points that charging needle manufacturers need to pay attention to when they want to improve the performance of their products, and I hope they can be of some help to you.
