Alloy resistor processed by composite material and preparation method thereof

Abstract

The invention discloses a preparation method of an alloy resistor processed by adopting a composite material. The method comprises the following steps: using the composite material, gouging, stamping into strips, trimming the resistor, packaging, removing glue, printing, stamping and separating, and electroplating. The beneficial effects of the preparation method are that: compared with such structures in the market, adverse factors such as unstable material resistivity, large welding seam, pseudo welding, welding drop, welding deviation and the like are effectively solved through the composite material, the gouging process and the like. And meanwhile, the effect of high-efficiency output (52PCS or higher produced by one composite material) can be realized, the investment of equipment is reduced, the number of operators is reduced, and the effects of reducing the number of workers and improving the efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of alloy resistors in semiconductor manufacturing, in particular to an alloy resistor processed with composite materials and a preparation method thereof. Background technique [0002] In the field of semiconductor manufacturing technology, alloy chip resistors are processed with three-piece welding materials in the manufacturing process. However, there are unfavorable factors such as unstable resistivity, large weld seam, easy virtual welding, welding drop, and welding deviation in the three-piece welding material, which may easily cause poor resistance of the product, crushing at both ends of the electrode, and plastic seals are not full of plastic, etc. Phenomenon, which increases the manufacturing cost for the enterprise and cannot supply to customers in time. At the same time, the welding materials still cannot manufacture products with smaller specifications (such as 0805), and the welding of five-piec...
