通孔(through-hole)是贯穿材料或结构的孔洞设计,广泛应用于电子工程、机械制造等领域。其核心功能包括元件固定、电气连接和机械定位
优点：耐久性强：Through-Hole焊接连接更牢固，对高温和震动有较好的耐受能力。维修方便：元件插入PCB孔中，维修时更容易进行元件更换，有利于维护和修理。适用性广：Through-Hole技术适用于各种应用场景，特别是对可靠性要求较高的场合。缺点：空间占用大：Through-Hole组件需要额外的孔位，占用了PCB板面积，限制了产品...
过孔本身存在着对地的寄生电容,如果已知过孔在铺地层上的隔离孔直径为D2,过孔焊盘的直径为D1,PCB板的厚度为T,板基材介电常数为ε,则过孔的寄生电容大小近似于:C=1.41εTD1/(D2-D1) 过孔的寄生电容会给电路造成的主要影响是延长了信号的上升时间,降低了电路的速度。举例来说,对于一块厚度为50Mil的PCB板,如...
