Metal dome arrays on adhesive tape are often aligned by visual placement methods or using a placement fixture. Snaptron offers custom placement fixtures for easier, more accurate placement of metal dome arrays. Custom Peel-N-Place fixtures are affordable, more precise than visual alignment, and make placing arrays easy.
How to Place Dome Arrays with Application Fixtures
STEP 1: Remove the array from the liner material and place it on spring-loaded registration pins (adhesive side up). 
STEP 2: Place the board on spring-loaded stand-offs and align the board with edge guides. 
STEP 3: Press the board down onto the array to secure placement.
