What this manufacturer makes
Smartron Technology manufactures flexible printed circuits and provides circuit assembly in Suzhou. Its official history dates the operation to 1998 and describes its relationship with Hongxin Electronics. The product catalogue distinguishes single-sided FPCA, double-sided FPCA with hot-bar connections and multilayer assemblies. The double-sided service below includes an assembly stage, so a buyer should distinguish the bare flexible circuit specification from connector, component and hot-bar requirements when comparing quotations.
