<p>A method for manufacturing electrical circuit traces (203) adapted for use in electro- chemical sensors is disclosed, as well as electrochemical sensors made from that method. The method includes providing a web (200), with a substrate (202) and a thin, electrically conductive portion (201) on the substrate. The web is positioned with a mask (300) between it and a source (P) of high energy, non-laser photonic energy. The method discloses emitting at least one submillisecond burst of high energy, non-laser photonic energy from said source toward the web with the mask therebetween. The photonic energy is substantially blocked by a photo-opaque portion of the mask. A portion of said non-laser photonic energy transmits with sufficient energy to ablate the portions of the electrically conductive portion exposed to the photonic energy, leaving the circuit traces on the web in the form of a repeating array of traces adapted for use in electro-chemical sensors. Using a high energy, broad spectrum light source instead of a laser reduces costs and allows wider webs and faster web speeds in reel-to-reel manufacture.</p> |
