Method of manufacturing planar bio-test strip and product thereof

A planar bio-test strip, comprising:

• a carrier plate, made of a plastic film;
• a conductive circuit, installed on the carrier plate, and further comprising:
• a testing electrode terminal, formed by coating or printing an electrically conductive material;
• and
• an electrode circuit terminal, electrically conducted with the testing electrode terminal, such that after the testing electrode terminal is formed, the electrode circuit terminal has a shadow mask printed onto the carrier plate, and an evaporated metal conductor is formed on the shadow mask;
• and
• an enzyme reacting area, coupled to a front end of the testing electrode terminal.

A method of manufacturing a planar bio-test strip, comprising:

• (1) using a roll of cylindrical plastic film as a carrier plate, and applying a printing method to construct a shadow mask provided for developing a pattern of a testing electrode terminal and a pattern of an electrode circuit terminal;
• (2) forming a conductive circuit by an evaporation process, and using the evaporation process to coat a continuous conductive electroplated layer onto the carrier plate that is printed with the shadow mask;
• (3) removing the conductive electroplated layer covered by the shadow mask, wherein the conductive electroplated layer covered by the shadow mask is removed by a physical method, and the whole conductive circuit is exposed, and the conductive circuit includes a testing electrode terminal and an electrode circuit terminal electrically conducted with each other;
• and
• (4) setting an enzyme in an enzyme reacting area disposed on the carrier plate.

A method of manufacturing a planar bio-test strip, comprising:

• (1) using a roll of cylindrical plastic film as a carrier plate, and printing or coating an electrically conductive material that is not chemically reacted with the enzyme easily on the plastic film to form a testing electrode terminal;
• (2) constructing a shadow mask on the carrier plate by a printing method, wherein the shadow mask is coupled to an end of the testing electrode terminal;
• (3) covering the electrode circuit terminal and the testing electrode terminal that is disposed away from the enzyme reacting area on the carrier plate printed with the shadow mask by an evaporation process, such that the electrode circuit terminal and the testing electrode terminal are electrically conducted, and coupling electrodes are formed at upper and lower layers of the testing electrode terminal respectively;
• (4) removing a block of the conductive electroplated layer covered by the shadow mask on the carrier plate to expose the testing electrode terminal and the electrode circuit terminal, after the evaporation process is completed;
• and
• (5) setting an enzyme in an enzyme reacting area on the carrier plate.
