Why You Should Use Whale Cleen sonic Ultrasonic Circuit Board Cleaner? 

 
Everyone has gone straight from soldering to testing a circuit board with good results, so is cleaning really need?
For precision work, absolutely. Even a small amount of solder residue, solder flux, dust, dirt, and grim can cause a measureable and significant change in behavior in a circuit, sometime it can even prevent a circuit from working entirely. Scrubbing a circuit board with a soft brush with alcohol can remove a lot of the surface contaminates, but the residue left is still enough to have an effect on circuit performance. The only way to really clean a circuit board is to use an ultrasonic cleaner.

 Things You Should Know Before Buying:

First specification point to consider is ultrasonic power. Without getting into the nitty-gritty, more power usually indicates faster and more effective cleaning, but more power is not always better. For example, too much power can damage electronic parts and other delicate items. For cleaning extremely sensitive items, equipment with adjustable power allows the PCB manufacturer to experiment to select the best power for a given PCB, or to accommodate a variety of PCB configurations.
It is critical that the supplier has a cleaner that accommodates the OEM’s PCBs. While this seems to be a “no brainer,” it is essential when it comes to specifying cleaning tank dimensions and, equally important, cleaning basket dimensions (which are slightly less than tank dimensions). The baskets hold the PCBs in a vertical position without crowding or board-to-board contact and must be of sufficient size to allow total immersion in the cleaning solution. This spec is called working depth and is the distance between the bottom of the basket and the surface of the cleaning solution. If this information is not available on the spec sheets, ask the manufacturer to supply it.

How To Clean With Whale Cleen sonic Ultrasonic Circuit Board Cleaner?

Cleaning tanks have a fill line to indicate the maximum level of cleaning solution. The supplier should fill the tank half way with water, add the correct amount of cleaning solution concentrate for a full tank, and then continue adding water to the fill line. The unit is turned on to mix and degas the solution. Degassing fresh cleaning solutions removes trapped air that interferes with cavitation. Degassing time depends on solution volumes but generally takes 10–15 minutes. Some units are equipped with a degas mode that can speed the operation.
It is important to note that PCBs will cause solution displacement. An experienced PCB supplier will know how to accommodate displacement. The point to keep in mind is that an overfilled or underfilled tank should be avoided. Once the solution is prepared, it is ready to clean the PCBs. The operating parameters are set and the unit is turned on. The PCBs are placed in the basket or rack and lowered into the solution. The timer is set. At the end of the cycle, the PCB is removed and inspected. If it is a go, the boards are rinsed with deionized water to wash away cleaning solution residues and allowed to dry.
