Introduction<\/h2>\n\n\n\n

Selecting the right RJ45 connector mounting method is a critical decision in network hardware design. From industrial automation to consumer electronics, the way an RJ45 connector is attached to a PCB directly affects electrical performance, mechanical reliability, and manufacturing efficiency. The three most common approaches\u2014Through-Hole Technology (THT)<\/strong>, Surface-Mount Technology (SMT)<\/strong>, and Through-Hole Reflow (THR)<\/strong>\u2014each serve specific engineering goals. In this guide, we break down these methods in detail and introduce real-world examples from LINK-PP<\/a>, a leading RJ45 connector manufacturer.<\/p>\n\n\n\n

Overview<\/strong><\/h4>\n\n\n\n

THT<\/a> involves inserting connector pins into drilled holes on the PCB, with solder joints formed on the opposite side\u2014typically using wave soldering<\/strong><\/a>. This traditional technique offers strong mechanical retention and has long been the standard in industrial and high-reliability environments.<\/p>\n\n\n\n
