Design and Technology Solutions

GDSI’s Double Sided Polymer Circuitry (D/SPC^®) provides circuit technology which eliminates the failure points inherent in designs using printed cross-over, bridging or jumpers which place silver circuit traces over another trace with only a screen printed dielectric separating the traces.  D/SPC^® eliminates these typical failure points.  

Design Fault	Solution
Water Ingress	Gasket (full perimeter seal), and Carbon printed over silver traces
Silver Migration	Gasket (full perimeter seal), and Carbon printed over silver traces
Cracked traces on tail	D/SPC® to move traces to inside radius
Actuation force variable between keypads	Proper design and tight tolerance manufacturing capability
Minimal packaging space	D/SPC® or double sided copper circuitry
Backlighting metal dome keypads	Electroluminescent panel using D/SPC® for increased reliability
Cracked overlay on keypad locations	Proper design and material selection
Rim embossed keypad alters actuation force	Stack up height, keypad spacer, and keypad dimension needs design improvement
High density keypad with multiple circuit tails	D/SPC® reduces the need for multiple tail exits
Expense	1) matching proper materials to OEM requirements 2) reducing or eliminating assembly costs at OEM 3) reducing or eliminating field failures
