Most Common Way of Securing Tactile Domes to your PCB

Snaptron offers Peel-N-Place arrays which is the most common way to secure tactile domes to your PCB or flex circuit.  Typically, metal domes are not meant to be soldered.  When a dome is actuated, the center of the dome collapses making contact at the center.  As this happens, the legs of the dome flex out. […]

Choosing Tactile Dome PCB Board Plating

When evaluating the type of PCB pad plating you will need with tactile dome contacts, it is important to ask yourself two questions: 1. What is the product life cycle requirement? 2. What type of contact resistance do I require? The circuit pad base is often copper, which will oxidize if not plated. Nickel has […]

Placing Metal Domes in Membranes Can be Tricky

Placing metal domes quickly and accurately in membrane applications can be tricky. Typically, domes arrive in bulk form and are packaged in jars. Getting domes placed quickly can be challenging and “double doming” common. At Snaptron, we have invented a proprietary technology that allows for fast placement and assures only one dome is placed in […]

The Importance of Venting a Metal Dome

The movement of air in and out from under the dome is called “venting” and it is important to have so the metal dome functions properly. Lack of venting can cause adverse effects on the feel and function of the switch. Venting metal domes is crucial in order for the dome to feel the way […]

Why Snaptron developed the DT-Series dome contact…Part V

What are the benefits of incorporating this dome contact into medical devices? How is that accomplished with existing devices? The DT-Series domes can produce two electrical contacts with a single dome. Benefits of metal domes include: low profile high reliability competitive price This is a new innovative technology that is open to the creativity of […]
