Double-Sided Green Lead-Free Tin-Plated Semi-Through Board

Double-sided green lead-free tin-plated through-hole board with a semi-hole structure that has been electroplated, forming a 360° fully encapsulated conductive layer, effectively enhancing the welding strength of the hole walls and the stability of signal transmission. The board is treated with lead-free tin plating process, ensuring environmental compliance while providing excellent solderability and oxidation protection for the semi-hole pins. This product is particularly suitable for communication gateways, industrial IoT edge computing terminals, and high-density integrated instruments that require direct board-to-board insertion. It effectively saves connector space and improves system integration.
