Abstract: A plurality of semiconductor devices having flanged edges are loaded into a first apertured tray with the leads extending in an outward direction. A second apertured tray is placed over the first tray and both trays are inverted with the transistors supported on the second tray and their leads extending downward into the apertures of the second tray. A third tray having counter-sunk apertures is placed on the second tray and after both are inverted, the transistors with their leads are positioned within the counter-sunk apertures. A blocking slide is then mounted over the third tray which is then inverted and positioned over a fourth tray having insulating pads positioned in counter-sunk apertures. Removal of the blocking slide will allow the leads of the transistor to drop through apertures in the insulating pads.

Abstract translation: 具有法兰边缘的多个半导体器件被装载到具有沿向外方向延伸的引线的第一有孔托盘中。 将第二有孔托盘放置在第一托盘上方，并且两个托盘都被倒置，其中晶体管被支撑在第二托盘上，并且它们的引线向下延伸到第二托盘的孔中。 具有防沉没孔的第三托盘被放置在第二托盘上，并且在两者都被反转之后，具有它们的引线的晶体管被​​定位在反沉没孔内。 然后将阻挡滑块安装在第三托盘上，然后将其倒置并定位在具有定位在反沉没孔中的绝缘垫的第四托盘上。 去除阻挡滑块将允许晶体管的引线通过绝缘焊盘中的孔落下。
