发明名称 Electronic device fabrication method comprising twofold cutting of conductor member
摘要 A fabrication method for an electronic device includes four steps. The first step is for preparing a leadframe with first and second conductive members. The second step is for connecting a first and a second electronic chips to the first and the second conductive members, respectively. For the third step, the first chip is enclosed by a first resin package allowing partial exposure of the first conductive member, while the second chip by a second resin package spaced from the first package. For the fourth step, the exposed part of the first conductive member is cut. The cutting is performed using first and second tools, where the first tool makes an indentation in the exposed part on a first side. On another side opposite to the first side, the second tool makes a full cut to be linked with the indentation.
