Conformal coating, potting and component securing for electronics that must function reliably under demanding conditions.
When electronics remain unprotected, the risk of failures and quality problems increases.
Moisture, condensation, dust, salt spray and vibration do not attack assemblies suddenly but over months. That is why unprotected electronics rarely show up in testing – but at the customer, after the component warranty period and in the middle of operation. The protection costs a fraction of what a field failure costs in replacement, travel and trust. The real hurdle is a different one: hardly any electronics manufacturer wants to set up its own system, exhaust air treatment and process qualification for this step.
Which process is the right one depends on the place of use, the assembly and the quantity. We do not offer one process for everything but select it together with you – and qualify the process before series production starts.
The coating lands exactly where it belongs – and not on connectors, contact surfaces or components that must remain free. This replaces laborious masking, which costs time in series production and is still never entirely reliable. The application is reproducible, so lot 500 turns out like lot 1.
Where the entire assembly needs protection, a thin, contour-following layer covers components and solder joints. It keeps out moisture, dirt and leakage currents without costing significant weight or installation space – and without impeding heat dissipation.
For the toughest applications, the assembly is fully potted. This protects not only against media and moisture but also mechanically against continuous vibration, shock and temperature changes – and incidentally shields your know-how from prying eyes.
Heavy or tall components are fixed against vibration so that the solder joint does not become a predetermined breaking point. And because such decisions have to be made early: we also coat individual samples and small series so that you can test the process before committing to series production.
Fields of application: EMS, OEMs, automotive, medical technology, industrial electronics, traffic control technology, defense, agriculture and smart home.
Coating and potting processes are missing in-house or tie up resources unnecessarily.
You offer your customers coated assemblies without setting up a system, exhaust air and process qualification yourself – we take over the step as an extended workbench.
Failure risk, quality pressure and audit readiness have to be served at the same time.
Qualified, documented processes with defined layer thicknesses – verifiable in the audit and reproducible across the entire series.
Electronics must run reliably for years under demanding conditions.
The protection process is designed for your real operating conditions – coating and potting linked to quality and operational reliability instead of a standard recipe.
Hardly any coating provider can be found for samples and small quantities.
We also coat individual samples and small series flexibly – so that you can test the process before series production starts.
The protection costs cents per assembly. A field failure costs the replacement part, technician deployment, downtime at the customer and, in case of doubt, the follow-up order.
Since 2006, we have coated and potted more than ten million assemblies – across industries, materials and operating conditions.
Anyone who has their coating done with us once usually stays. That has less to do with the process than with deadlines that are met and contacts who are reachable.
You save yourself the system, exhaust air treatment, material storage and process qualification – and are still able to offer coated assemblies.
Condensation, dust and leakage currents no longer reach the conductor track. Exactly the failure patterns that occur in the field and never in the lab.
Protected assemblies age more slowly. This extends service life and reduces warranty cases in exactly the applications where they are most expensive.
From the single prototype to the ongoing series – without a minimum quantity that slows down your development.
Pieper Coating has done nothing but protect electronics since 2006. Over ten million coated and potted assemblies later, this has turned into experience that cannot be drawn from data sheets: which material suits which assembly, where selective is better than full-surface, and when potting is the only right answer.
This specialization is the real point. For an electronics manufacturer, coating is a side process that requires a system, exhaust air, material storage and qualification. For us, it is the main process – with ESD-compliant handling, defined layer thicknesses and audit-ready documentation that your customers want to see in the audit.
As part of the Bauer MSG Group, we are the Protect stage of a group that develops, manufactures, protects and maintains electronics. If an assembly needs more than coating, the rest of the chain is already standing by.
The fastest way to the right decision is a coated sample in your hand. Tell us where the assembly will be used and what must remain uncoated – we will propose the suitable process and produce a sample before you commit to series production.
