What are the applications of round hole stitching in THE THR skill?

In recent years, appearance mounting skills have developed with agility and have taken on an insignificant role in the electronics industry. In addition to the scale effect of fully automated production, SMT has the following skill advantages: components can be mounted on both sides of the PCB for high density assembly; Even the smallest scale components can perform precision mounting.

Convenience of operation and mechanical strength of round hole needle are also important factors. Connectors are usually the interface between the PCB motherboard and external components, so sometimes they may encounter considerable external forces.

The through-hole component is much more reliable than the corresponding SMT component. Regardless of compact, and easy to mount, and through hole circular hole needle in the size and form of assembly has obvious differences.

The processing of round hole and row bus used for industrial field wiring is usually the high-power component is the intense pull, kneading or thermal shock, it can accept, but not easy to be removed from THE PCB.

In some cases, these advantages are eroded by the reduction of component adhesion on the PCB. SMT components are characterized by design. Can meet the transmission of high voltage, high current demand. Therefore, sufficient electrical voids and creepage intervals must be considered in the design, which will ultimately affect the size of the component.
