Precision Assembly is a Matter of Micron-Level Accuracy
When you’re assembling micro-scale components at industrial speed, the margin for error is effectively zero. A glue path 50 microns too wide, a weld a fraction off target, or a curing cycle misaligned by seconds — any of these can compromise structural integrity or lead to downstream failures. And in a world of thinner devices, that risk only grows.
As part of our broader offering in automated test & quality assurance solutions, Averna builds integrated, automated assembly systems engineered for extreme precision and consistency. We combine vision-guided robotics, sensor-based alignment, real-time inspection, and smart process control — so every bond is verified as it happens. Working with adhesives, ultrasonic welding, or UV curing? Our precision assembly services eliminate manual variability and scale your throughput without sacrificing quality.
A Full Suite of Precision Assembly Services
Our turnkey solutions combine proven test & measurement, control systems, machine vision, gluing/welding and robotics.
Vision-Guided Robotic Assembly
Our expertise in vision inspection, mechatronics and automated test equipments automation come together in extremely precise alignment operations based on sensor feedback.
We use 2D/3D vision, laser triangulation, and smart sensors to guide micron-accurate motion and real-time positioning. This enables us to automate complex assemblies while continuously verifying quality at each step.
Expertise includes:
- Vision-guided mechatronics for micron-level positioning
- Absolute-positioning systems with integrated quality inspection
- Handling of miniaturized or fragile components with precision
- Active alignment for optical components and assemblies
- Human-Like Inspection for quality assurance
Ultrasonic and Laser Welding Automation
Our systems integrate laser and ultrasonic welding into your production environment with high accuracy and repeatability — eliminating manual joining errors and minimizing thermal impact on sensitive components.
Welding together mechanical parts in modern devices requires ultra-precise positioning. For this, we often use a combination of different technologies, including vision inspection and motion.
Using high-frequency ultrasonic acoustic vibrations to create a solid-state weld has numerous advantages. Say goodbye to connective bolts, nails, soldering materials or adhesives needed to bind the materials together.
Expertise includes:
- Ultrasonic welding for plastic or hybrid materials
- Laser welding with vision-controlled alignment
- Automated welding validation with real-time inspection
Oven & UV Curing Systems
We use the latest absolute-positioning technologies to support automated gluing or ultrasonic welding operations, followed by UV or oven curing. These ensure consistent strength, reduced curing times, and high production throughput.
Expertise includes:
- Glue dispensing paths as tight as 1.5 mg over 50 mm
- UV and oven curing integrated into high-speed lines
- Process optimization for different adhesive chemistries
Precisely Assembled for You to Take the Next Step.
Looking to validate a concept or solve a complex assembly challenge? Our team can support your project at any stage — from early engineering prototyping and consultancy to full-scale production. Averna helps you reduce risk and get to market faster.
Automated Production + Integrated Quality Inspection
Our turnkey systems can ensure both high throughput and perfectly accurate assembly. Depending on your needs, they can be semi- or fully automated.
Due to the continuing trend of product miniaturization with increased complexity, our automated assembly and test systems merge essential steps. Accurate gluing, welding, laser and assembly solutions are key for next-generation devices.
As a result, the clear distinction between assembly and testing starts to blur. In smartphones, for example, testing and soldering the battery is one step in the production process. Hence, a combination of ultra-precise dosing, fixation, positioning and real-time feedback is essential to ensure best results and maximum reliability.
Precision Assembly in Action with a Glue-Dosing Solution
With modern devices being mostly glued together, the glue path needs to be as accurate and thin as possible, while still ensuring solidity. We’ve increased Océ’s production level and ROI by implementing a self-calibrating vision system and volumetric-glue dosing solution.
