Reliable Partner for Safety Critical Electronics Manufacturing
We support European manufacturers of high reliability electronics with qualified, reproducible cleaning processes, delivered discreetly, designed to scale, and built for long term industrial partnerships.
ZESTRON’s Value Proposition for Defense and Aerospace Electronics
We deliver qualified and stable processes for the precision cleaning of electronic assemblies used in mission-critical systems—from development through to secure series production. In the event of deviations, we respond quickly and with a focus on solutions to maintain process reliability at all times.
Our processes create reproducible surface conditions and optimally prepare assemblies for downstream coating processes—an essential prerequisite for moisture-resistant, durable, and reliable electronics. This is where our defense experts work closely with leading manufacturers of cleaning systems that are qualified for the defense and aerospace sectors.
At the same time, we provide support for key challenges facing the defense industry:
-
Transitioning qualified processes to scalable series and mass production
-
Stabilization of production parameters for small to high volumes
-
Accelerated industrialization within a short timeframe
-
Workshops tailored specifically for the defense sector
Proof of Purity Analytical Validation for Combat-Rugged Electronics
Specialized analytical methods for determining surface cleanliness enable the detection of even the slightest ionic impurities that can impair the adhesion and long-term stability of protective coatings.
For standard-compliant purity and quality verification, our in-house analytical center at our German facility offers state-of-the-art methods, including:
- ROSE Test (full-board analysis)
- C3 (spatially resolved ROSE Test)
- Ion Chromatography (IC)
- SIR tests for evaluating electrochemical migration
This ensures validated cleaning processes for functionally critical assemblies.
Additionally, further analytical methods are available for verifying coating quality to reliably demonstrate the long-term stability and reliability of coated assemblies:
- Coating Reliability Test: Stress test for electrochemical migration
- Coating Layer Test: Test for defect-free coating
Proof of QualityVerifiable Factors of Trust and Quality
We strive for long-term partnerships. Trust and reliability are essential to this.
