The invention discloses circuit board proofing and printing equipment using metallic tin. The equipment comprises a printing box; the printing box is internally provided with a printing cavity; and the inner wall of the left side of the printing cavity is provided with a through feeding cavity. According to the circuit board proofing and printing equipment using the metallic tin, by utilizing goodelectrical conductivity and low melting point of the metallic tin and the relative movement between a steel mesh and solder paste, the solder paste can be uniformly covered on a single-sided board ina circuit electrifying mode, a mixture in the solder paste is heated and evaporated, and the solder paste is molded to form a stable circuit; and meanwhile, after a circuit board is used, the metallic tin can be recycled again by heating, so that the cost is saved. Due to the fact that the equipment can print and manufacture the single-sided board at will, the cost and the time for manufacturingthe circuit board at the earlier stage are reduced, meanwhile, a test link of circuit board design is simplified, the difference between printed circuit boards and later-stage batch circuit boards issmall, and proofing errors can be greatly reduced.
Description
technical field [0001] The invention relates to the related field of circuit boards, in particular to a proofing and printing device for circuit boards using metal tin. Background technique [0002] PCB circuit boards are generally green. Regardless of the power supply of the processor or the signal transmission between components, they are all completed through the metal wires printed on these small boards. They are often mass-produced by professional equipment in huge workshops. But before mass production, developers need to make several circuit boards for testing. This kind of original creation, breadboard proofing. Users insert wires, sensors, resistors and other components on a whiteboard densely covered with interfaces to simulate the performance of the final electronic product. It is very convenient to change the design on the breadboard, but its huge size, and the reliability and performance are not consistent with the finished product, making the early development ...
