我厂生产2C7S系列产品,是一种较小的塑封管,其引线零件见图1。 根据工艺要求,其基板(管芯基板)与中间工艺筋连接,待封制后才可切除工艺筋部分,考虑保证间距达到较高精度,在下工艺筋外加工艺孔,以便作为导向,跳步间距是6±0.005mm,材料是H62,厚度δ=0.4mm。工件的工艺简图见图2。 I 2C7S production plant products, is a smaller plastic pipe, the lead parts shown in Figure 1. According to the process requirements, the substrate (core substrate) is connected with the middle process bar, and the part of the process bar can be cut off after being sealed. Considering that the spacing can reach higher accuracy, the process bar can be additionally applied at the next process bar so as to guide and jump the gap Is 6 ± 0.005 mm, the material is H62, the thickness δ = 0.4 mm. The workpiece process diagram shown in Figure 2.
