Ultrasonic Generator PCB Board
We design and manufacture the ultrasonic generator PCB board for welding, cutting, bonding, emulsification and cell disruption — supplied with a matching transducer, booster and horn.

The board that controls the whole stack
The ultrasonic generator PCB board is the printed circuit board that carries the electronics generating and controlling the ultrasonic vibrations in an ultrasonic system. It regulates the frequency, the power and the duration of the drive signal, which makes it the heart of every welding, cutting and sealing machine.
We supply the board together with the transducer, the booster and the horn as a complete system, and custom horns are available. Because the board and the stack are specified together, the frequency window and the power match are correct from the first run - no mismatched stack, no re-tuning on site.
One board, five frequencies

Eight advantages of the board
DDS & PID control core
DDS and PID high-precision frequency-control core.
Constant amplitude
Electric constant-amplitude control system holds the output steady.
1% amplitude steps
Welding amplitude setting range 0% to 100% in 1% steps.
Soft start 0-999 ms
Soft-start setting range 0-999 ms with 1 ms precision.
Three self-checking modes
Three self-checking modes verify the board before it runs.
Three trigger modes
Pressure-trigger, time and energy welding modes.
Six protections
Six protection functions guard the tool and the workpiece.
Compact and light
Small footprint with a total weight of only 1.3 kg.
Twelve ways a generator board is used
The board is chosen by the machine it is built into. These are the duties it most often controls - each one a different combination of frequency, power and cycle.

Ultrasonic welding
Fuses plastic and metal components in automotive, electronics and medical manufacturing.
See plastic processing →
Ultrasonic cutting
Drives cutting blades for clean cutting of food, rubber, plastics and textiles.
See food cutting →
Ultrasonic sealing
Creates airtight seals in packaging materials, keeping product fresh and intact.
See plastic processing →Ultrasonic emulsification
Emulsifies liquids and mixtures into stable, homogeneous products in food and pharmaceutical production.
Ultrasonic soldering
Runs ultrasonic soldering machines for strong, reliable solder joints on electronic components.
Ultrasonic textile bonding
Joins fabrics and creates patterns on textiles under board control.
Cell disruption
Extracts cellular contents in laboratories and biotechnology.
Homogenisation
Homogenises mixtures and suspensions for product consistency.
Vibrating screens
Separates and classifies materials in agriculture and mining.
Weld inspection
Inspects welded joints for defects in non-destructive testing equipment.
Thickness gauging
Measures material thickness in industrial ultrasonic gauges.
Board, transducer and horn matched as one system
The board is not shipped on its own. Because the board and the stack are specified together, the frequency window and the power match are correct from the first run - and the custom horn is made to the same frequency.
Boards are tested before dispatch, and the matching transducer, booster and sonotrode are confirmed against the same frequency so the system works as delivered.

Questions buyers ask before ordering
Will this board fit my generator?
Boards are matched to specific generator models. Send us your model or a photo of the board and we will confirm the fit.
Do boards come with firmware?
Yes — each board ships with the control firmware loaded and ready to run.
What's the OEM minimum?
OEM / ODM quantities are flexible; tell us your volume and we will quote the minimum.
Can you supply transducers to match?
Yes — we supply matched transducers, boosters and horns for the same frequency and power.
Tell us the frequency and power you need
Send the frequency, the power and the duty of your application and we will specify the matching board, transducer, booster and horn as one system.
