This TYPE C female seat 6PIN sinking board 1.6 four pin plug-in board adopts precision design, with a sinking board thickness of 1.6mm, suitable for the space requirements of ultra-thin equipment. The four legged plug-in board structure enhances the fixing strength of the PCB board, with an overall length of L=6.8mm, making it compact and small. The terminal is made of brass material (with a copper content of about 65%), which has excellent conductivity and can stably transmit data and power; The insulator is made of LCP material, which is resistant to high temperatures of 260 ℃, corrosion-resistant, and has strong insulation properties. The design without shrapnel simplifies the structure, reduces the risk of poor contact, and is suitable for scenarios such as smart wearable devices and small electronic accessories that require high space and stability.
