3. Through-Hole技术介绍: Through-Hole技术是一种将电子元器件通过孔穴插入印制电路板(PCB)并焊接的制造技术。其主要特点包括: 耐久性:Through-Hole组件的焊接连接更牢固,耐高温和震动。 维修方便:Through-Hole组件插入PCB孔中,维修时较容易进行元件更换。 适用性广:Through-Hole技术适用于各种电子产品,特别是对可靠...
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...
What is Through-Hole? Definition Through-hole is a method for mounting components on a printed circuit board (PCB) in which pins on the component are inserted into holes in the board and soldered in place. Find a term alphabetically: ...
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...
The components are placed on the PCB, inserting each pin into a corresponding through-hole. The PCB is passed through a solder process, whereby, within each through-hole having a component pin inserted therein, the solder paste is wicked into the through-hole, and forms a solder joint with ...
Thechemical-free through-hole platingprocess LPKF ProConduct® metallizes through-holes with diameters of up to 0.4 mm and aspect ratios of up to 1:4. At 19 milliohms on average, the electrical resistance of the plated-through holes is extremely low. ...

This difference arises because placing through-hole components requires drilling holes in your PCB, which incurs tooling costs. In contrast, drilling is not required with surface mount components, which accounts for the cost difference. All this begs the question: if surface mount components are smal...

For these reasons, it is easy to think that all PCB components should be surface mount parts. However, there are many good reasons why through-hole parts are still used when assembling circuit boards: Power supply: For components used in high-power circuits, SMT packaging is not a good choi...
