Concurrent Technologies are experts in ruggedization; and the development and manufacture of products for use in critical embedded applications.

Ruggedization is a big part of our process. We offer suitable products for increasing levels of operating temperature range, shock and vibration including three typical operating temperature ranges plus rugged variants.

Humidity protection and conformal coatings are offered to provide reliable operation in different environmental conditions.

Covers

RCx-Series rugged conduction-cooled boards are available with extended covers (RCR-series), with standard covers (RCS-series) and without covers (RCT-Series). The covers are designed to protect against Electrostatic Discharge (ESD) damage and ensure mechanical robustness when handling, allowing a Two Level Maintenance Scheme.

Three coating types are offered as standard: a humidity seal based on fluorochemical polymer that dries to a thin layer and enables boards to be used continuously in 85% humidity; two types of conformal coatings that offer improved moisture and chemical resistance properties for more extreme environments. Other coating types available to special order.

Coating Type Description
1 Certonal® FC-742 Humidity seal
2 Humiseal® 1B73 Acrylic conformal coating
3 Humiseal® 1A33 Urethane conformal coating
