Avoid Failures Before They Occur

Tailor-Made. Reliable. Experienced. - ZESTRON Reliability & Surfaces


Ionic or particulate contamination on the surface can cause electronic assemblies to malfunction. To minimise the risk of failure and ensure reliability, our experienced Reliability & Surfaces Team (R&S) offers customised technology coaching.

Electrochemical migration, leakage current or a short circuit are typical failure mechanisms. Within the scope of technology coaching, our R&S team advises and supports you on how to avoid failures and produce reliable, moisture-resistant assemblies - along the entire value chain.

YOUR ADVANTAGESAvoid Failures and Produce Reliable Assemblies

1.  Preventive assessment of the risk of default before production starts

2.  Analysis of failures during validation tests

3.  Cause analysis in case of damage in the field


SOLUTION-ORIENTEDDriven by Reliability

On the way to solving your challenge, the first step is to identify the (potential) failure mechanism. To do this, we use a wide range of analytical methods such as SEM/EDX, ion chromatography or fracture stress analysis. We put the results into the overall context of your problem and then work out feasible measures to solve it.
