Introduction to THR Connector

Through-Hole Reflow (THR) connectors are a type of electronic connector that combines the advantages of both through – hole and surface – mount technologies. They are designed to be inserted into pre – drilled holes on a printed circuit board (PCB) and then soldered using the reflow soldering process. This technology offers high mechanical stability, which is beneficial for connectors that need to withstand vibrations and mechanical stress. THR connectors are widely used in various industries such as automotive, telecommunications, consumer electronics, and industrial control systems due to their reliability and ease of assembly.
