Ultrasonic Cleaning Machine for Printed Circuit Board Cleaning

Ultrasonic cleaning machine for printed circuit board cleaning
Ultrasonic cleaning machine of circuit board is gentle and thorough
Ultrasonic cleaning of electronics plays a crucial role in assuring reliability of the finished products, Flux and Solder paste removed from assembled, misprinted and reworked circuit board, which is very critical process steps, ultrasonic cleaning removes flux, even tenacious residues, even the lead-free and low-residue fluxes from printed circuit bard with either through-hole technology or surface-mount components, ultrasonic cleaning of electrical components offers clear advantages over spray washing when the components has tight clearances or tubular geometries
01: rapidly achieves high level of cleanliness
02: will not damage delicate assemblies
03: cleans components with blind holes or complex geometries
04: Uses aqueous or semi-aqueous cleaners
05: Increases reliability of finished electronic products
Printed Circuit board ultrasonic cleaning helps to improves SIR test results while reducing rework and increasing PCB reliability, Ultrasonic cleaning electrical assemblies with delicate components is a safe way to remove contaminants from parts easily susceptible to damage, tiny precision assemblies have inaccessible surface that cannot be cleaned by other methods, Electronic device can be safely cleaned in water with the appropriate chemical agent as longas they are properly dried, Many persons hold the belief that electronic cannot be placed in water, this is simply not ture, an circuit board ultrasonic cleaning can be used quite effectively to maintain and restore a broad range of equipments
KEEPLEADER offer machines/equipments designed for optimum cleaning of circuit boards and electronics, our Ultrasonic cleaning with sweep technology can eliminate the possibility of any damage caused by stationary wave
Advances in ultrasonic technology for electronic industry
If you regularly clean electronic parts, an ultrasonic cleaning is the best tool for this kind work, the common concern is that ultrasonic cleaning will destroy delicate components, however, advances in ultrasonic technology have eased this concern by replacing the single frequency wavelength approach-know to harm electronic parts-with a variable frequency approach, called "sweeping" this advance is ultrasonic technology has not only led to reduced production costs, but has proven to enhance reliability, thus reducing warranty costs as well
FOR printed circuit board cleaning or cleaning populated PCBs, the aim is to remove flux residues from PCBs, State-of-the-art PCB cleaning processes are able to effectively remove all types of flux residues, ranging from RMA to newly developed synthetic material  
Although the so called No-clean production has proved itself for many production purpose in the low-end area, the cleaning of high-end assemblies is essential, to ensure the reliability of bonding and coating processes, it is utmost importance to clean the assemblies before bonding/coating, resin and activator residues that lead to poor coating and bonding adhesion, as well as corrosion and electrical failure are not removed from the assembly during No-cleaning manufacturing processes, furthermore, lead-free solder pastes and flux systems newly introduced to the market during the conversion to lead-free soldering contain a higher content of resin and more aggressive activators, modern cleaning technologies have therefore been designed to cope with no-clean formulations, and with adequate equipment optimization this can be prevented, KEEPLEADER offer water-based, Semi-aqueous and water-free cleaning processes, various cleaning systems are available for cleaning both lead-free and lead-basked assemblies
How to use an ultrasonic cleaning to restore electronic and PCBs
Dust, dirty and corrosion can impact the performance of printed circuit boards (PCBs) used in electronic equipment exemplified by sophisticated hand-held devices such as iphones, some of which have been accidently dunked, can be restored, KEEPLEADER is suggesting to use ultrasonic cleaning along with ultrasonic cleaning solution expecially formulated for delicate electronics
Selecting an ultrasonic cleaning machine
Ultrasonic cleaning machine, such as the tabletop, stationary series are ideal for small volume user in cleaning or used as household device, KEEPLEADER can make to size and make customized function, e.g: heating power, timer, counter, temp display, resetting, cycling and filtering mounted and etc, the multistage ultrasonic cleaning machine is recommended for big factory, manufacturer. For them, KEEPLEADER will consider the automatic loading, unloading and transmit among cleaning process, as well as drying system, water purification auxiliary
How to select and use the cleaning solution
The wrong cleaning solution, just as the wrong ultrasonic cleaning frequency, can do more harm that good, an ultrasonic cleaning solution ideal for glass and ceramic substrates, optics, PCBs plastic parts is the biodegradable concentrate detergent, is removes grease, oil, activated fluxes, dust, fingerprints, light corrosion and residues from coffee, tea, colars, milk and other sources
Depending on the extent of contamination this concentrate is diluted 3% to 10% with water, the recommended ultrasonic cleaning time is 3 to 10 minutes at approximately 65C/150F, after cleaning the parts, must be rinsed in distilled or deionized water, this is very important in order to remove any traces of cleaning solution residue, because tap water also will leave residue deposit, it must not be used as a rinse, dry the components thoroughly before reassembly
Note, that these are only guidelines of KEEPLEADER, the user should consult with the ultrasonic cleaning professionals at KEEPLEADER regarding equipment, solution and procedures to meet your requirements
Other suggestion from KEEPLEADER
A fresh batch of ultrasonic cleaning solution contains entrapped air, you can see evidence of this by the bubbles that appear on the inside of a glass of water standing at room temperature, this air interferes with the cavitation process and must be driven off before you begin the cleaning operation to do under steps;
01: add water and correct portion of cleaning concentrate to the tank's fill line
02: set the temperature dial
03: turn on the ultrasonic cleaning to start the degassing operation
The rising temperature coupled with the cleaning chemicals and ultrasonic energy will speed the degassing operation and at the same time thoroughly mix the contents of tank, when air bubbles not longer rise to the surface, you are ready to clean the parts, place them in the mesh basket, taking care to keep them from contacting each other, lower the basket into the basket into the cleaning solution and set the timer, as you become experienced with ultrasonic cleaning PCBs and other electronic components, you will become more proficient and efficient, the engineer at KEEPLEADER are ready to help you reach this goal by selecting the ultrasonic cleaning model, frequency, power, cleaning solution, cleaning process that meets your requirements
