Pin needle use pay attention to what matters?
Pin needle use pay attention to what matters?
pin needlePrecautions for use: 1. The compression amount is generally 2/3 of the total stroke. During the assembly process, attention should also be paid to avoid bumping the nozzle and causing the pin needle to be stuck. Too much pressure will cause the nozzle wound to jam the pin needle. Too little pressure will lead to insufficient positive force, which will lead to unstable obstruction.
The pin is applied in the contact direction.
2, andpin needleThe paired battery touch or flexible circuit board gold fingers must not have dirt, oxidation, etc.
A: There should be no residual sealing liquid
The contact surface of the pin pin pair shall be free of dirt, etc.
B: There shall be no residual dirt

pin needleThe spring pin looks like a simple part, but if you do not have a good level of quality control and perfection in the production process, and it is easy to disconnect the pin, or the durability (life) is too short. Its process is extremely sophisticated, from lathe processing, electroplating, assembly, each process may bring serious hidden dangers.
Such as lathes, Japan should adopt heart automatic lathes, so parts can be guaranteed in/-0.01mm accuracy, suitable for most factories are missing knife processing, precision is absolutely no way to guarantee. Second, the surface finish of lathe processing, especially the inner surface finish of the needle tube is very critical. The vast majority of surface roughness testing equipment factories do not have the supervision of this important parameter.
