Given Imaging, a medical technology company, came to GM Nameplate (GMN) to assemble a membrane switch panel for their medical device. When configuring a membrane switch, many factors about each component layer must be taken into consideration.
As the user interface for a medical device, the screen printed and embossed overlay needed to satisfy stringent requirements. The overlay must act as a sealant to prevent moisture and fluids from reaching the membrane. Additionally, the overlay must be chemical and scratch resistant to combat the strain of daily use.
Common overlay materials include polyester and polycarbonate. Both materials are affordable options that will protect the circuit membrane from scratches, chemicals, and liquids. Due to the durability of screen printed inks, backprinting is a frequent practice to mitigate product wear and tear from everyday use.
This Given Imaging overlay contains three colors - teal, white, and a black opaque layer. The opaquing layer was selectively applied around the LEDs which allowed light to shine through and prevented light bleed through unwanted areas of the overlay. Because of the opaquing layer, light only showed through the indicator icon on a button instead of throughout the whole part.
When looking at membrane circuit materials, printed silver ink in lower volumes provides a cheaper option than copper etched circuits, such as Kapton, while still offering comparable performance capabilities. Finding the right membrane circuit for the product application is necessary to manufacture a quality membrane switch.

As a printed electronics manufacturer, GM Nameplate manufactures membrane switches and other electronic components for various industries including medical. GM Nameplate has been working with specialty pharmaceutical company AcelRx since 2009, printing a membrane switch and overlay for their Zalviso device. The device is used for post-operative pain management.
The overlay features a selectively textured front surface and tactile buttons to make it more use friendly. It also features a window for the device’s display screen. This window added a challenge to the part, as it required rigidity and durability without increasing the size of the membrane switch or thickness of the overlay material. GMN created a unique solution for AcelRx by combining the dome spacer with a window stiffener layer and optically bonding this component to back of the overlay.
In the electronics industry where components are constantly getting smaller, it is imperative to have adequate technical printing resources to yield robust and reliable circuits to avoid any malfunction when in use – and when the component is used on a medical device the stakes are higher. Stringent printing and inspection procedures are in place to ensure that every element of the membrane and overlay meets customer specifications.
This membrane switch is a great example of GMN’s expert electronic printing capabilities in highly regulated industries, and the type of products we will be showcasing at MD&M West in a few weeks. The final parts meet all the technical customer’s requirements while provide the necessary durability and wear resistance needed.

One of the growing capabilities at GM Nameplate is front panel integration. We currently provide the front panel integration for many customers across nearly every industry. Recently, we provided ultrasound device manufacturer, Fujifilm SonoSite with front panel integration for their X-Porte ultrasound kiosk device.
For the X-Porte device, we provided the decorative cover glass and bonded the cover glass to the display. The manufacturing process involved printing specialty ink and Sonosite’s reflective chrome logo. Once decorated, the cover glass was integrated to the display using our liquid optically clear adhesive (LOCA) bonding process.
Before going into production, significant time was spent developing the inks and process to ensure that the liquid adhesive to cure. Once everything was set, the production team faced various challenges in assuring the best quality display. Due to the design, there were extremely tight tolerances in both the printing and bonding process
The end result? A beautifully bonded front panel display assembly, with added durability and sunlight readability benefits!
GM Nameplate has been providing components to Microsoft for their Xbox systems since the original device, and including the latest Xbox One. Our China facility manufactures various parts on the Xbox One including a capacitive touch membrane circuit, badging, labels and more.
The flexible circuit is one of the most interesting parts that we manufactured for the device. The circuit utilizes capacitive touch technology for the power on/off and optical disc drive (ODD) eject switch. Utilizing this technology increases durability, as there are no mechanical components and meets all the functional needs of the switch. Our engineering team worked closely with the Xbox team to create a cost effective design meeting all the performance criteria.
In addition to the flexible circuit we also manufactured two 2D electroform logos (in addition to labels and other components) for the Xbox One console and Kinect device. To meet the desired aesthetic GMN developed a unique process to tint the 2D electroform to achieve Xbox One’s unique dark chrome color. This process can be used to create a variety of shades and colors for 2D electroform parts. The GMN produced logos can be found on the top of the console and on the Kinect device.
Our work with Microsoft on components for the Xbox One is a great example of how our diverse capabilities can serve multiple needs of a customer – in turn reducing supply chain costs and simplifying logistics. The GMN capabilities featured on the Xbox One can be found on various other products across nearly every industry.
