Product details
Apply a layer of photosensitive transparent dry film with a thickness of 5mm on the surface of electroplated conductive foil. The photosensitive transparent dry film is made of resin, and the parameters for applying the photosensitive transparent dry film are: temperature of 100 ℃, speed of 1.0m/min, and pressure of 6kg. Using negative film graphics, the photosensitive transparent dry film is irradiated with ultraviolet light to undergo polymerization reaction. The transparent part of the negative film is transferred to the photosensitive transparent dry film through the exposure of ultraviolet light by the exposure machine. Use Na2C03 solution with a concentration of 1.0% (w/v) to remove the photosensitive transparent dry film that has not undergone polymerization reaction, completing the graphic transfer. When applying PET with 0CA adhesive onto the pattern of photosensitive transparent dry film, avoid generating bubbles.
Technical indicators:
1. Full light transmittance of over 85%, high transparency;
2. The thickness of the copper wire (i.e. the height of each copper wire) is 5m, and the overall thickness is within 15 μ m. The structure is lightweight and does not affect the wearing of contact lenses;
3. The peel strength is within the range of 15~20N/25mm, with excellent reliability;
4. The environmental resistance performance has reached high temperature of 95 ℃ x1000h and low temperature of 40 ℃ x1000h, with stable molecular structure and no harm to the human body;
5. The electrical and wireless performance connections meet the performance requirements, with a blood glucose detection accuracy rate of over 95% and high accuracy. The bending resistance meets the requirements and can meet a service life of 3-5 years. Require no layering or bubbles.
