說到線路板的清洗，目前比較流行的清洗方式主要是使用pcb板超聲波清洗機（也可稱為線路板/電路板超聲波清洗機）進行的，清洗對象不外乎是焊錫留下來的松香、助焊膏，使用久了留下來的灰塵，或者是帶風扇的電路板如電腦主板、顯卡等，時間久了也會積留一些頑固性污漬等。使用傳統的清洗方法的話就是用清洗劑浸泡清洗了，或者使用軟毛刷清洗，但是這種清洗方法不僅費時費力，也容易損壞pcb板。而使用pcb板超聲波清洗機，就可以很好的解決這個問題。
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.

為什么這么說呢，其實這個主要還是有超聲波清洗原理決定的，當超聲波作用于液體中的時候，溶液中會產生無數的小氣泡，氣泡在聲壓或者聲強受到的壓力到達一定程度的情況下，氣泡迅速膨脹然后又突然閉合。在氣泡不斷膨脹閉合的過程中瞬間產生沖擊波，這種超聲波空化產生的巨大壓力，不斷地沖擊著物體的外表，從而來達到剝離污物的目的。但有一點一定要清楚的是，超聲波清洗機的作用是純物理上的清洗作用，如果在遇到一些用清水比較難以去除的污垢時，比如除油、除銹、除拋光蠟等一些化學成分的污物時，就需要有加熱功能的超聲波清洗設備，以及專用的清洗劑配合清洗來達到清潔的目的。
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.
對于添加清洗劑，其實就像我們日常生活中洗碗要加洗潔精，洗衣服要加洗衣粉或洗衣液是一個道理的。那么pcb板超聲波清洗機如何清洗線路板呢？超聲波清洗物件的步驟其實都大相徑庭，購買超聲波清洗設備時一般都有配送超聲波清洗籃，清洗時將pcb板放在超聲波清洗籃上，注入一定量的清水，再加入適量的清洗劑，便可以啟動pcb板超聲波清洗機了，要注意的是pcb板不要堆的太緊湊，留有一定的空隙可以使清洗效果達到佳。
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.
