说到线路板的清洗，目前比较流行的清洗方式主要是使用pcb板超声波清洗机（也可称为线路板/电路板超声波清洗机）进行的，清洗对象不外乎是焊锡留下来的松香、助焊膏，使用久了留下来的灰尘，或者是带风扇的电路板如电脑主板、显卡等，时间久了也会积留一些顽固性污渍等。使用传统的清洗方法的话是用清洗剂浸泡清洗了，或者使用软毛刷清洗，但是这种清洗方法不仅费时费力，也容易损坏pcb板。而使用pcb板超声波清洗机，可以很好的这个问题。
When it comes to PCB cleaning, the current popular cleaning method is mainly to use pcb board ultrasonic cleaning machine (also known as PCB/PCB ultrasonic cleaning machine). The cleaning objects are only rosin and solder paste left by soldering tin, dust left after long use, or pcb with fan, such as computer motherboard and video card, which will also leave some stubborn stains after a long time. If the traditional cleaning method is used, it is to soak and clean with detergent or use a soft bristle brush. However, this cleaning method is not only time-consuming and laborious, but also easy to damage the pcb board. Using pcb board ultrasonic cleaning machine can solve this problem well.

为什么这么说呢，其实这个主要还是有超声波清洗原理决定的，当超声波作用于液体中的时候，溶液中会产生无数的小气泡，气泡在声压或者声强受到的压力到达一定程度的情况下，气泡迅速膨胀然后又突然闭合。在气泡不断膨胀闭合的过程中瞬间产生冲击波，这种超声波空化产生的巨大压力，不断地冲击着物体的外表，从而来达到剥离污物的目的。但有一点一定要清楚的是，超声波清洗机的作用是纯物理上的清洗作用，如果在遇到一些用清水比较难以去除的污垢时，比如除油、除锈、除抛光蜡等一些化学成分的污物时，需要有加热功能的超声波清洗设备，以及专用的清洗剂配合清洗来达到清洁的目的。
Why do you say that? Actually, this is mainly determined by the principle of ultrasonic cleaning. When the ultrasonic wave acts on the liquid, countless small bubbles will be generated in the solution. When the sound pressure or the pressure on the sound intensity reaches a certain level, the bubbles will expand rapidly and then close suddenly. In the process of continuous expansion and closure of bubbles, shock waves are generated instantaneously. This huge pressure generated by ultrasonic cavitation constantly impacts the surface of objects, so as to achieve the purpose of stripping dirt. However, it must be clear that the role of ultrasonic cleaning machine is purely physical cleaning. If some dirt that is difficult to remove with clean water, such as oil removal, rust removal, polishing wax removal and other chemical components of dirt, you need to have a heating function of ultrasonic cleaning equipment, as well as special cleaning agents to cooperate with cleaning to achieve the purpose of cleaning.
对于添加清洗剂，其实像我们日常生活中洗碗要加洗洁精，洗衣服要加洗衣粉或洗衣液是一个道理的。那么pcb板超声波清洗机如何清洗线路板呢？超声波清洗物件的步骤其实都大相径庭，购买超声波清洗设备时一般都有配送超声波清洗篮，清洗时将pcb板放在超声波清洗篮上，注入一定量的清水，再加入适量的清洗剂，便可以启动pcb板超声波清洗机了，要注意的是pcb板不要堆的太紧凑，留有一定的空隙可以使清洗效果达到佳。
For adding detergent, it is just like in our daily life that detergent should be added when washing dishes, and detergent or detergent should be added when washing clothes. So how does the pcb board ultrasonic cleaning machine clean the circuit board? In fact, the steps of ultrasonic cleaning of objects are quite different. When purchasing ultrasonic cleaning equipment, ultrasonic cleaning baskets are usually delivered. When cleaning, place the pcb board on the ultrasonic cleaning basket, inject a certain amount of water, and then add an appropriate amount of cleaning agent. The pcb board ultrasonic wave cleaning machine can be started. It should be noted that pcb boards should not be stacked too tightly, and a certain amount of space should be left to achieve good cleaning effect.
