PCB 厚度设置为≥0.7mm。 PCB thickness is set to ≥ 0.7mm. 不规则 PCB而没有制作拼板应加工艺边，不规则的 PCB 制成拼板后加工有困难时，应在 两侧加工艺边。 PCB did not produce an irregular jigsaw edge technology should be added to, Irregular post-processing of PCB is made difficult jointed board should be added on both sides edge technology. 1.1.2 1.1.2 PCB PCB 工艺边要求工艺边要求 1.1.21.1.2 PCB PCB 工艺边要求工艺边要求 PCB edge technology demands 距 PCB 边缘 5mm 范围内不应有焊盘、通孔、MARK 及小于 3mm 宽的走线。 Within 5
