Description

Through hole return line to board connector

Technical Field

The utility model belongs to the technical field of connect the plug components and parts, concretely relates to through-hole return line is to board connector.

Background

Through-hole reflow soldering is a new technology in international electronic assembly application, and gradually takes an important position to replace wave soldering. The through hole reflow soldering process is to place a template on the PCB, smear solder paste to fill the through hole with the solder paste, and then perform reflow soldering after inserting components. Because the insertion of the element is completed in the later stage, higher requirements are provided for the pin of the element, the pin must be ensured to be in a straight state, and the reflow soldering effect of the through hole is influenced by the bending, inclination and other conditions of the pin.

Most connectors on the market adopt SMT paster reflow soldering and wave soldering modes, and manufacturing cost is higher compared with through hole reflow soldering.
