3 Key Steps for Installation of a Membrane Switch

Finding the proper membrane switch for your device isn’t always easy. It’s crucial you take the necessary time to evaluate your product needs. There are many factors to consider from what materials to use, the conditions the switch will be exposed to, what price you’re willing to pay and more.

When applying your membrane switch to your product, here are three key steps to remember.

 Step #1: Handling/Testing

An important step that many times gets overlooked,  you will want to test your membrane switch before starting installation. While handling your membrane switch remember never to press a switch button unless it’s lying flat on a solid surface. Do not bend the switch and make sure to use anti-static wristbands to protect sensitive components from (ESD) electrostatic discharge. We recommend you test all tactile and non-tactile responses of the membrane switch prior to installing it.

Step #2: Mounting Surface

After testing to make sure your switch functions correctly, check the surface you’re mounting the membrane switch against. This surface should be clean and smooth. It must not have rough texture, residue (from adhesive, paint, etc.), burrs, bumps, steps, or hardware protrusions.

Step #3: Installation

During installation, you will want to keep the membrane switch as flat as possible. If the part is bent, it may cause damage to the domes. Starting at one end, fold back a small strip (approximately 1/2 inch wide) of the release liner from the edge. Align the part and stick down the free end, and then remove the rest of the liner. Smooth the part down with a light, slow stroke, working from the starting edge toward the opposite end to prevent air bubbles. Avoid applying extreme pressure or rolling the part down as you’re working across. After the part is on your mounting surface, use a firm but smooth rubbing motion over the entire surface to complete the bonding of the pressure sensitive adhesive. Never use a roller to apply pressure.

If the membrane switch has a tail, never bend or pull back the tail to the point where it causes creasing, as this may cause the switch to function intermittently or fail completely.

4 Things That Are Now Possible Thanks to Printed Electronics

Printed Electronics Copyright Wilson-Hurd 2014

Printed electronics are a set of printing methods used to create electrical devices on a number of substrates. They are produced by combining various printing methods to deposit electrically functional & optical inks onto a substrate. The inks can be deposited in any pattern to suit the type of application it is being made for. The end result is a lightweight, flexible electrical device, developed with a cost-effective production process.

The versatility of printed electronics is a huge draw for all manufacturers and markets. The benefits of these new electronics are endless, from lower cost, improved performance, flexibility, transparency, reliability, and much more. Even though the printed electronics market is still growing, there are some things that have been made possible in recent years, including:

  1. Printed Antennas

Printed antennas are relatively inexpensive to design and manufacture. They have a variety of useful properties including mechanical durability, conformability, compactness, and cheap manufacturing costs. They also have a range of applications in both the military and commercial sectors, and are often mounted on the exterior of aircraft and spacecraft as well as incorporated into mobile radio communication devices.

  1. Wearable Technology

Wearable technology is made with smart sensors and has the ability to connect to the Internet and collect data. Examples of wearable devices include watches, contact lenses, e-textiles and smart fabrics, types of medical devices, and jewelry such as rings and bracelets. The goal of wearable technologies in each of these fields will be to smoothly incorporate functional, portable electronics and computers into individuals’ daily lives.

  1. Smart Labels

Smart labels can be attached to any package, even packages that may bend, and they can provide real-time information about location, temperature, movement, and moisture. With smart labels, companies can also confirm the freshness of products by checking the temperature to prevent spoilage and validate the authenticity of a product. In the healthcare field, smart labels can help control inventory and track the usage and disposal of pharmaceuticals. Smart labels are also being attached to clothing where they can check body temperatures and dampness of bandages.

  1. Flexible OLED DisplaysFlexible_display

OLEDs are used to create digital displays in devices such as television screens, computer monitors, and portable systems such as mobile phones and handheld game consoles. They are also used in commercial applications such as displays for car radios and digital cameras, among others.

Printed electronics are one of the fastest growing technologies in the world, and allows electronics to be in places they have ever been before. The market is destined to grow as technology evolves, allowing for even more possibilities to develop.

Designing a Touchscreen: Where to Begin

Touchscreens are gaining popularity with manufacturers as an alternative to other switching technologies, and it is easy to see why. When it comes to user interfaces, touchscreens have successfully changed the way electronic equipment is used by simplifying the user experience and eliminating the need for buttons or keys. If you are considering incorporating a touchscreen into the design of your product, there are key items that you should consider.

First you should understand the difference between a resistive touchscreen and a capacitive touchscreen.

Resistive TouchscreenResistive Touchscreen Illustration

A resistive touchscreen is constructed using two clear conductive layers (typically a glass or acrylic substrate and a polyester top sheet) that are separated by insulating dots. When the user touches the screen and compresses the top flexible layer, electrical contact occurs between the top and bottom layer.

Capacitive TouchscreenCapacitive Touchscreen IllustrationRGB

Voltage is applied to the corners of a capacitive touchscreen and distributed by a pattern of electrodes located around the touchscreen periphery. This creates a uniform electric field across the conductive surface. When the user touches the screen with a conductive object (such as their finger), they are drawing a minute amount of current from the surface. This change in capacitance is measured at each point on the touchscreen allowing the touch position to be located.

Before you actually sit down and design your touchscreen, there are at least four main considerations you need to take into account:

  1. Environmental conditions
  2. Software requirements
  3. Firmware requirements
  4. Appearance

These will help you determine the materials and types of technology to utilize in your touchscreen. For each consideration there are a number of questions you will need to ask yourself:

Wearable Technology You Didn’t Know Exists

Wearable technology is a device typically made out of printed electronics, which is worn by a consumer that has the ability to connect to the Internet and collect data. It is the main topic of conversation in the tech world today. While the most common wearable is currently the smartwatch, there are many other wearables out there that you may not have even known existed.

Glucose Measuring Temporary Tattoos

A researcher from the University of California created a flexible sensor to measure the glucose levels in a person’s body. These temporary tattoos use a mild electrical current to monitor the vitals and can later be disposed of after use. This is a pain free alternative to the traditional finger-stick device that diabetic patients may find unpleasant. The tattoos are relatively inexpensive and can be replaced without too much financial burden.

Sensoria

Sensoria is a smart fitness sock that assists users on their running techniques in real time. The sock has sensors on the bottom of the foot that transmits feedback to a removable anklet which in turn syncs the information to a smartphone app. The device monitors cadence, which is the way your foot hits the ground as you run. By monitoring your technique, you not only improve your running, but also prevent any future injuries.

Kiband

The Kiband is a wireless bracelet to monitor the location of a child. Parents using the Kiband can set custom distance perimeters to make sure their children are within sight. When the child is getting too close to the edge of the perimeter chosen by the parent, the bracelet will vibrate warning the child they have gone too far. The parent will also be notified when the child crosses the set perimeter by an alarm on the mobile app. The app will then help the parent locate where the child is.

UpRight
