Hagiwara Solutions Co., Ltd. (headquarters: Naka-ku, Nagoya City, President: Junji Hada) started “conformal coating”, an optional coating service that expands the use of flash storage products in various conditions, such as harsh or harmful environments.

Overview

Depending on equipment installation locations, such as the production plant or outdoors, flash storage products face risks of unexpected failures caused by humidity, dust, cutting oil, and/or chemical contaminants.
To ensure the reliability and availability of the product in such harsh environments, we offer the optional service to perform insulation protection coating along the surface of the flash storage.
The coating also reduces TCO (Total Cost of Ownership) by maximizing product life.

Features

Two types of coating materials

Acrylic coating and urethane acrylate coating are available with different resistances and advantages.
The urethane acrylate coating provides an even better protective effect against salt water and oil by forming a more resistant coating film.

MIL-I-46058C

The conformal coating meets the military-grade of thermal shock test standards.

UL94V-0

High flame retardant that meets the flame retardant grade “UL94V-0”.

RoHS

Compliant with the EU　RoHS Directive to restrict the use of certain hazardous substances.
