"Never put electronic products in water" is a common sense that we have been taught since childhood. Any electronic products are easy to corrode or have uncontrollable faults when encountering water. The ultrasonic cleaner cannot be used because of the presence of water. Of course not. This is not the case.

謠言終結(jié):電子產(chǎn)品和水可以混在一起。

The rumor ends: electronic products and water can be mixed together.

實(shí)際上，拔掉插頭的電子設(shè)備可以放在水中。訣竅在于超聲波干燥。如果用水清洗電子設(shè)備，那么接觸點(diǎn)可能會(huì)被任何碰撞的灰塵和碎片污染。為了防止污垢在原位干燥，在干燥過程中使用化學(xué)物質(zhì)會(huì)消除污垢。

In fact, electronic devices that are unplugged can be placed in water. The trick is ultrasonic drying. If the electronic equipment is cleaned with water, the contact point may be contaminated by any colliding dust and debris. In order to prevent the dirt from drying in situ, the use of chemicals during the drying process will remove the dirt.

你可能聽說過，用去離子水代替自來(lái)水，你的電子產(chǎn)品就安全了。就像普通的水，當(dāng)你開始用去離子水清洗電子設(shè)備時(shí)，里面充滿了灰塵和污染物。

You may have heard that if you use deionized water instead of tap water, your electronic products will be safe. Just like ordinary water, when you start cleaning electronic equipment with deionized water, it is full of dust and pollutants.

將電子設(shè)備從水中取出后，需要用化學(xué)清潔劑清潔任何接觸點(diǎn)，化學(xué)清潔劑一定要起到排水和潤(rùn)滑劑的作用。這將防止關(guān)鍵接觸點(diǎn)的污染。

After the electronic equipment is taken out of the water, it is necessary to clean any contact point with a chemical cleaner, which must play the role of drainage and lubricant. This will prevent contamination of critical contact points.

不用擔(dān)心電子設(shè)備上的焊點(diǎn)。

Don't worry about solder joints on electronic equipment.

似乎超聲波清洗機(jī)中使用的振動(dòng)可能會(huì)損壞電子設(shè)備中存在的非常脆弱的焊點(diǎn)。還好超聲波沒那么干凈。

It seems that the vibration used in the ultrasonic cleaning machine may damage the very fragile solder joints that exist in the electronic equipment. Fortunately, the ultrasound is not so clean.

超聲波清洗機(jī)的工作原理是產(chǎn)生小氣泡，這些小氣泡會(huì)一次又一次地出現(xiàn)和破裂。這個(gè)過程被稱為空化。因?yàn)闅馀菔乔鍧嵉尿?qū)動(dòng)力，所以焊點(diǎn)是安全的。

The working principle of the ultrasonic cleaning machine is to produce small bubbles, which will appear and break again and again. This process is called cavitation. Because bubbles are the driving force for cleaning, solder joints are safe.

焊接過程中使用的一種化學(xué)物質(zhì)，叫做助焊劑，是廠家用超聲波去除主板上的殘留物。

A chemical substance used in the welding process, called flux, is used by manufacturers to remove residues on the motherboard with ultrasonic.

使用超聲波清洗機(jī)選擇適當(dāng)?shù)念l率。

Use an ultrasonic cleaner to select the appropriate frequency.

你一定要非常小心的一件事是頻率。一般來(lái)說，27-40k Hz之間的頻率適合清洗電子產(chǎn)品。如果頻率設(shè)置過高，可能會(huì)造成損壞。

One thing you must be very careful about is frequency. In general, the frequency between 27-40k Hz is suitable for cleaning electronic products. If the frequency is set too high, damage may occur.
