大功率LED散热铁基板
铁基印制电路板(铁基PCB/铁基板)其基板材料是具有磁性 能的铁元素的合金(如矽钢板、低碳钢、镀锌冷轧钢等)构成。应用于小型精密电机上。线路制作工艺符合国家标准及IPC标准。

Iron PCB is made by the alloy of iron with magnetic force (eg.silicon steel board,low carbon steel,inc-plating cold rolled steel etc.)It'sapplied on minitype precision engines and the arts and crafts meet the national standards and IPC standards
