In the electronics manufacturing sector, speed and precision are essential, especially when managing varied product lines such as control units, communication modules, and electronic enclosures. These are often produced in low-to-medium volumes across high-mix environments where geometries change frequently, design updates are constant, and the cost of test inefficiencies can be significant. To meet these demands, leak testing workflows must be robust, sensitive, and agile; capable of ensuring protection without slowing production.
The Challenge: Complex Components and Production Variability
Manufacturers in automotive electronics and telecom infrastructure face a consistent set of challenges:
- Design diversity in parts like ECUs, sensor housings, and mobile communication boxes.
- Small leak paths that compromise IP ratings or allow ingress of dust and moisture.
- Frequent product changeovers that introduce delays if test systems aren’t flexible.
- Protecting sensitive internals from contamination during testing.
These pain points affect manufacturers who require test methods that preserve product integrity, scale efficiently, and support their global QA and MES frameworks.
A System Built for High-Mix Electronics
We address these challenges through our Custom Engineered Solutions (CES) platform. Here’s how it supports high-mix electronics lines:
Flexible Fixture Design
Adaptable fixtures accommodate different enclosure shapes and sizes without requiring complete retooling. This speeds up changeovers and ensures repeatability across product variants.
Rapid Reconfiguration
With programmable and selectable test recipes and quick-swap tooling, test lines can adapt to different SKUs in minutes, not hours. This reduces bottlenecks and supports short-run, high-mix manufacturing without excess downtime.
High Sensitivity and Dry Testing
To detect micro-leaks in electronics, we use high-precision vacuum and pressure decay methods that eliminate the need for invasive or wet testing. These are:
- Non-contaminating for delicate internals
- Suitable for sealed, high-IP-rated enclosures
- Designed to detect leaks at the micron scale
Automation & MES Integration
A Nolek system can include full robot integration and MES/ERP compatibility, enabling:
- Hands-free testing
- Data traceability at the unit level
- Compatible with QA systems
ROI and Traceability Built In
Electronics buyers are under pressure to justify capital spend and reduce risk. Our CES systems are designed with that in mind:
- Reduce false rejections by tuning sensitivity to each product type
- Cut maintenance costs with predictive diagnostics and easy calibration
- Minimise CapEx waste by scaling a single system across multiple lines or locations
With unit-level data logging, traceability is embedded, supporting downstream failure analysis, QA documentation, and recall readiness.
Designed for the Realities of Electronics Manufacturing
High-mix electronics manufacturing demands speed, control, and confidence in test outcomes. The Nolek CES solution provides:
- Micro-leak detection without contamination
- Support for frequent product changes
- Compliance with global quality standards
- ROI through efficiency and uptime
This isn’t just testing, it’s integrated process control.
