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\u2014C\u00f4ng ngh\u1ec7 L\u1eafp r\u00e1p Qua L\u1ed7 (THT)<\/strong>, C\u00f4ng ngh\u1ec7 L\u1eafp r\u00e1p Tr\u00ean B\u1ec1 M\u1eb7t (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
