Problems solved by technology

[0002] A resistor is a current-limiting element in an electronic circuit, which acts as a shunt or a voltage divider. At present, the resistance element is usually fixed on the circuit board by welding. This method is not only complicated in fixing the resistance element, but also high in cost. , the production process of components is also complicated and a time-consuming and consumable process; printing resistance paste directly on the circuit board instead of resistance components can save labor and material costs and improve production efficiency; but the existing resistance paste When screen printing is used, the printing performance is poor, and the paste curing time is long, resulting in low production efficiency, low adhesion, and poor resistance stability under high temperature impact

Abstract

The invention discloses resistance copper slurry and a preparation method thereof, and belongs to the technical field of electronic slurry. The resistance copper slurry is mainly prepared from the following components in parts by weight: 12-16 parts of trimethylolpropane triacrylate, 25-28 parts of N-vinyl pyrrolidone, 3-6 parts of bivalent acid ester, 38-45 parts of epoxy acrylic resin, 2-5 partsof fatty alcohol polyoxyethylene ether, 1-3 parts of a surfactant, 8-13 parts of an initiator and 80-100 parts of silver-coated copper powder. The resistance copper slurry has the advantages of excellent printability, short curing time, strong adhesion force, high temperature resistance, moisture resistance, resistance to solder resist ink erosion, and stable resistance value. The preparation method of the resistance copper slurry is simple in process, easy to prepare and high in production efficiency; the produced product has good quality and low production cost.
