Product Overview
Our Double-sided Tin-Sprayed PCB is manufactured using advanced PCB fabrication technology and Hot Air Solder Leveling (HASL) surface treatment. The HASL process provides a durable solder coating on the copper surface, ensuring excellent solderability, high reliability, and cost-effective production.
Double-sided tin-sprayed PCBs support circuit routing on both sides of the board, offering higher wiring density and better design flexibility. They are widely used in consumer electronics, industrial control, communication equipment, automotive electronics, and security systems.
