Flexible circuits for the computer peripherals market include:

• Printer switch assemblies
• Touchpads
• Keyboard membranes

Sample Applications

printer switch assembly

Printer switch assemblies:

• Poly-Solder® is a highly reliable conductive adhesive
• Low cost alternative to a rigid PCB flat cable assembly
• Eliminates rigid circuit board
• Eliminates PCB, flat flex cable and connector
• Integral switching
• Flex circuit contours to fit your product design
• Carbon over silver tail printing to improve abrasion resistance when inserted into wiping contact connector designs
• Hydrophobic dielectric for moisture resistance
• Printed spacer reduces cost by eliminating a separate mechanical spacer

touchpad

Touch pad assemblies:

• Single touch pad and component assembly eliminates a separate board and connector
• Reduced weight and profile when compared to rigid board alternatives (PCB thickness reduced to a maximum thickness of .012" from the FR-4 solution at .074"; overall weight reduction from 5 oz to 2 oz)
• Capacitive circuitry for the touch pad area
• PSA integrated to assembly for ease of installation
• Assembly includes 80pinQFPat.032" pitch

keyboard membrane

Keyboard membrane switch:

• High volume production reduces cost
• Low profile and light weight in desktop and notebook keyboards
• High operational reliability under severe environmental conditions
• Printed spacer switch pad design reduces package height and eliminates need for discrete spacer and spacer tooling
