Abstract

PURPOSE:To efficiently and securely seal a package by pushing out the shells from the lowest one, engaging it with the shoot bracket by pushing it, placing the shell opposing to the metal die through rotation and thereafter pressingly engaging it with the shell engaging part of metal force. CONSTITUTION:The lead frames LF housed in a magazine 1 are sequentially pushed out from the lowest one by a pusher, then supplied to a table 2 and then carried to a metal die. A shell S pushed out from a shell hopper 3 is pushed to the shoot brackets 23, 33 and is placed opposing to the metal forces 52, 62 after the welding surface is rotated for 90 degrees. It is then pushed out and is engaged with the shell engaging part. The metal forces 52, 62 are preliminarily heated and is then rotated further for 90 degrees. The dies are heated by a hot blower 76. Thereby the welding surface is fused and is then rotated for 90 degrees again. Thereby, the shell engaging parts are opposed face to face in both sides of lead frame LF. Here, the cylinders 58, 68 operate, causing a top force and a bottom force to slide in such a direction as they come close along the guide post 56.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a 582nd integrated circuit mounting apparatus that performs backing (mounting) in the final process of integrated circuit manufacturing. Regarding 1, is it an integrated circuit mounting device that can insert packages extremely efficiently and reliably? The purpose is to provide.

The uninvented feature is a mechanism that pushes out the Noelke from the highest stage in the shell hopper and presses it into the seed bracket, and a mechanism that rotates the sheet bracket l-'Y 90 degrees to form the mold Vc.
After facing each other, move it forward toward the mold, push it out from the shell chute bracket, and push it into the shell 11u mounting part of the mold. This is an integrated circuit mounting device consisting of a mechanism that rotates the mold by 790 degrees and a mechanism that brings the mold close to each other from both sides of the lead frame and hits the mounting device in this order. This shows an example. First, a detailed explanation of the present invention will be given with reference to FIG.
A large number of single-frame IJFs stored in stacks are pushed out by the hooks 1-- in order from the tenth stage, and sent to the table 21 for conveyance. - Power shell hopper: 'I Inner K The one shell S that is stored is delivered to Daruma Otoshi 11 and pushed into Noro + - Brackeno L-23. Next / Utobraknoto 237' J.(Turn 10 degrees and face the mold 52 1
In this state, move forward and press fit the shell S into the cross-shaped mold 52.

The mold 52 is rotated by 00 degrees, and during this time, the surface of the /L S (bonding surface) is heated and melted by the Hosotobrofle 75.76. The above configuration of s-3TJ soil should also be provided on the underside of table 2. And the mold 52,
