The horizontal pin micro base with a spacing of 5.9mm and a solder pad positioning column is the most commonly used and can be customized. The length of the shell solder pin is 0.8mm/1.0mm/1.2mm/1.6mm/2.0mm, and the plug-in board is relatively firm when passing through the PCB board. The fully SMT micro base with a solder pad positioning column is directly attached to the PCB board. The two models have different structural installation methods, which are convenient for mass production. The main focus is on how to design the PCB board reasonably. The quality of the micro USB products produced by Guangjiayuan is guaranteed and can be used with confidence, Call to inquire about free samples.
