Advancements in User Interface Assembly Materials in Medical Devices

Written by Ed McMahon - CEO
Posted on October 20, 2016 at 12:38 PM

Advancements in user interface assembly construction methods are often overlooked in the HMI applications as it is usually an afterthought and too many people assume that the older graphics, adhesive, rubber, and backlighting technologies are still the same. This is not the case, especially in medical applications.

Packaging For User Interface Assemblies

Written by Epec Engineered Technologies
Posted on May 14, 2015 at 11:22 AM

Packaging for user interface assemblies for shipment to customers is the last step in the manufacturing process. Epec pays as much attention to packaging detail as to design and manufacturing of custom  assemblies. Each custom assembly part number is by nature different size, mass, and shape because it is custom. However, styles of user interfaces can be grouped in several categories. Experience has shown the type of packaging that works best is based on complexity of construction, shape, size, mass and shipped unit volume. No one packaging solution works for every assembly style.

Can A Membrane Switch Keypad Be Waterproof?

Written by Epec Engineered Technologies
Posted on May 16, 2014 at 1:49 PM

In some applications including marine environments, medical devices, and consumer electronics there is a possibility for the user interface control panel to be exposed to water or liquid solvents. In these situations, it is critical that the electronic components are completely sealed from any outside containment's that could damage the built in electronics.

Why Use A PCB With A Membrane Switch

Written by Epec Engineered Technologies
Posted on March 3, 2014 at 12:33 PM

Many applications are better suited using a "membrane switch" (low profile, flat surface keypad assembly) with a rigid printed circuit board replacing screen-printed silver conductors on polyester sheets.

Printed circuit boards with gold plated switch contact pads and gold plated dome switches greatly improve the reliability of your application. Types of improved reliability consist of longer operating life, lower switch resistance and contact bounce.
