Abstract:
The invention provides a method of fabricating test strips for measuring biological blood. The method comprises steps: preparing an insulating membrane material; printing a metallic circuit layer on the insulating membrane material by a metallic ionic ink; performing a surface treatment for the metallic circuit layer expose metallic ions of the metallic ionic ink; chemical plating for the exposed metallic ions of the metallic circuit layer to form an electrode section on the metallic circuit layer; providing a sensing reagent on the electrode section to form a sensing reagent layer; sequentially adhering an intermediate layer and a cover to the insulating membrane material to cover the metallic circuit layer and expose part of the metallic circuit layer; and cutting the insulating membrane material to form a plurality of insulating sheets. The test strip is provided to enhance the stability of resistance and the test accuracy.
Abstract:
A thin key structure includes a supporting module, a circuit module disposed on the supporting module, a frame and a metal dome disposed on the circuit module, a pressable module, and a guiding portion. The supporting module has a supporting plate and a protrusion disposed on the supporting plate. The supporting plate has a plane defined therein, the plane defines a perpendicular central axis, and the protrusion is arranged on the central axis. The circuit module has a protruding segment formed by the protrusion. The metal dome is arranged in the frame, and has a contact portion arranged on the central axis. The guiding portion arranged on the central axis and is disposed between the contact portion and the pressable module. The metal dome is pressed by the guiding portion to move the contact portion along the central axis and selectively abuts the circuit module.
Abstract:
The present invention provides a multi-layer flexible circuit board, comprising at least an electric circuit disposed on a vertical interval layer, wherein at least two sides of the electric circuit are covered by neighboring interval layer and another vertical interval composed layer of electric insulating material. The disclosure provides a non-pressing way to stack the multi-layer flexible circuit board, preventing fault crevice derived from a prior-known pressing way.
