Machine Description

Stencil Ultrasonic Cleaning Machine

01: Parameter

02: Highlights

Stencil Ultrasonic Cleaning Machine can remove all types of un-reflowed solder paste, including lead-free, as well as uncured adhesives from stencils, screens and misprinted PCBs, safely and gently, its built-in wash-solution filtration and recirculation system cuts down on the amount of wastewater sent to drain while maximizing the useful life of your wash solution

03: Cleaning procedures

Simply place your stencil in the rack, fill with high quality cleaning solution and press the start button, ultrasonically cleaned by high-speed microscopic bubble implosions, after only a few minutes, manually lifts your cleaning stencil from the washing tank, and spray-clean by hand to remove the loosened solder paste and other contaminants. And dip into the rinsing tank, at last, use a low-pressure dry air gun removes the remnant rinse moisture and you stencil is ready to be used again all in only a few minutes

04: Advantages

041: Complete cleaning: microscopic, ultrasonic removal of solder pasts, post solder flux and more

042: Minimize wash solution costs: The machine built-in filtration and recirculation system to reduce the water consumption and reuse the wash solution

043: Adopts ultrasonic cleaning technology: Stencil Ultrasonic Cleaning Machine is using ultrasonic vibrating to stir and remove the un-reflowed solder, paste and uncured adhesives from stencils screens and misprints, gently and without risk of damage to delicate stencils

044: Washing, rinsing and drying functions are all in one machine: The machine design two sump, one is used for dirty cleaning, the other using rinsing, also built-in hot air drying system to quick dry after cleaning, all workstation included in one compact unit, minimizing required floor space

045: Customized size for various sizes of stencils: accommodates stencils, screen, and misprinted PCBs to 29”*29” (736*736mm)

046: Water level indictor: shuts down the machine if the water level drops below the minimum requirement to avoid damage

047: Dual tanks design: stencil ultrasonic cleaner has two ultrasonic tanks, a wash tank/sump and rinsing tank/Sump, both tanks have ultrasonic energy and heat, the cleaning tank equipped with filtering and recirculation to save the water consumption, reuse the cleaning solution and avoid secondary detain when pulling out the cleaning tank

048: Top quality: the ultrasonic vibrators are mounted at side of cleaning tank at 40khz, have ten year warranty against the be-bonding, the whole machine has two year of warranty, ultrasonic generator is smart to match the frequency with the machine, don’t need any further debugging, and support hog plug

Easy loading and unloading: low-profile, top-centric design requires no or minimal bending

Portability: the entire systems moves easily around your shop on casters

049: Easy maintenance: with easy-to- access, easy-to-replace parts, easy to program and operate.

05: Special notices

051: The ultrasonic frequency should be 40 kHz or higher (the lower the frequency, the more aggressive the ultrasonic cavitations)

052: The power density should be 10 watts per liter or less (this is the amount of electrical energy transferred into the cleaning bath via the ultrasonic generator, measured in watts per liter of cleaning solution in the tank).

053: The ultrasonic cleaning cycle should be less than 10 minutes (a correctly sized ultrasonic cleaner combined with the appropriate cleaning chemistry should effectively clean PCBs in 3 - 4 minutes).
