一种二极管的制造方法及由此制得的二极管
摘要：
本发明公开了一种二极管的制造方法及由此制得的二极管，本发明的制造方法包括二极管晶粒制备、填装、焊接、清洗封装步骤，本发明利用晶粒和焊片在高温下不同的热膨胀系数及形变，焊接前无需提前对正晶粒，即可实现焊接后晶粒自动拉正，气孔面积大大减小，提高焊接质量，经由氢氟酸：醋酸：硫酸：硝酸的体积比＝8.8:13:5.6:9.2制得的混合酸酸洗后的晶粒电性良率高。
摘要（英）：

The invention discloses a manufacturing method of a diode and the diode fabricated by the manufacturing method. The manufacturing method comprises the steps of diode grain crystal fabrication, filling, welding, cleaning and package. Due to different thermal expansion coefficients and deformation of a grain crystal and a welding sheet, the grain crystal can be automatically stretched after weldingwithout grain crystal alignment in advance before welding, the pore area is greatly reduced, and the welding quality is improved. A mixed acid prepared from hydrofluoric acid, acetic acid, sulfuric acid and nitric acid according to a volume ratio being 8.8:13:5.6:9.2 is high in grain crystal electrical conductivity after pickling.
