Ask：Q.How do I apply the metal domes to my p.c.b., membrane, or flex circuit?
Answer：A. Our metal domes are applied by means of pressure-sensitive adhesive tape. Several standard material options are available, as well as custom materials. See our Peel-N-Place Arrays for more information on placing the domes with tape.
Ask：Q.Is there a recommended actuator for depressing the domes?
Answer：A. While there are any number of different sizes and shapes of actuators, we test the actuation force of our domes with a .050 diameter, flat-bottom plunger. See Test Criteria for more information on testing the domes.
Ask：Q.How are the domes packaged?
Answer：A. There are several different packaging methods to choose from, depending on your specific application. The domes can be packaged in Bulk (jars) , on polyester-adhesive Sheets (Peel-N-Place Arrays), Peel-N-Place Arrays on Tape and Reel, and in Cartridges for use with the Dart™ Placement Pen and the SureShot™ Automated Dome Placement Machine.

Ask：Q.Can your domes be assembled with standard pick and place equipment?
Answer：A. At this time we do not offer our domes packaged in the standard ammo-pack for pick and place equipment. However, our tape and reel arrays are ready to be placed by a fully automated system. Why place one part at a time, when you can place all of your switches at once? Please contact us for details about using a fully automated dome array placement machine.
Ask：Q.What does it mean to over-travel a metal dome?
A. Most of our metal domes are designed to be depressed to flat and no further. However, in some applications more travel is required. Our M-Series metal domes are designed with an additional .005" travel past the flat plane. This means that the dome will exhibit its designed characteristics only when over-travelled. Conversely, the dome will not exhibit its designed tactile response when pushed to flat. The M-Series metal domes will accomodate this additional travel without damaging the metal dome.
