Abstract

PURPOSE:To weaken the adhesion of generated resin burrs so as to remove easily by arranging the constitution such that the resin leaked from space between the lead of a lead frame and the dam block stagnates in the space for resin collection. CONSTITUTION:A dam block 19 is biased onto the cavity 17 side, and a space 20 for resin collection whose right and left is caught with leads 14 is provided between the dam block 19 and a tie-bar 15, and the resin which has leaked from the space between the dam block 19 and the lead 14 is stagnated in the space 20 for resin collection and is hardened. If the resin is hardened in the conditions that the resin is not cast into the space 20 for resin collection this way, resin burrs 25 adhere under low pressure, so that adhesion is weak and its removal becomes extremely easy.

The manufacturing method of the present invention will be explained below. First, one mold, such as the lower mold (21), is fixed, and the other mold, such as the upper mold (23), is lifted by a press (not shown), and then the lead frame (11) is moved by the lower mold guide bin (not shown). It is loaded in the state shown in FIG. 1, and the upper mold (23) is lowered and tightened. As a result, both the front and back surfaces of the lead frame (11) form cavities (!) as shown in FIG. 2 or 3.
7), the upper mold (21) and the lower mold (23) are tightened except for the gate (18), and in this state the mold resin (2
4) is injected at a pressure of, for example, 100 kg/(?m" (7). Each cavity (17) has a gate (18)
It is connected to a runner (not shown) through which the mold tree Jfi (24) can be supplied.

Injected tree J! 1 (24) fills the cavity (17), the pressure applied to the resin (24) causes the resin (24) to move between the lead (14) and the dam block (
19) leaks from the gap between the Then, as shown in FIG. 3 or 4, the resin reaches a resin retaining space (20) surrounded by the side surfaces of the leads (14), and the pressure is released here. As mentioned above, the clearance between the dam block (19) and the door (14) is set quite tightly, so the speed at which the resin (24) leaks out is quite slow.
Therefore, the resin (24) stagnates in the resin retention space (20) and hardens into resin burrs (25) before filling the resin retention space (20). Thereafter, the upper mold (23) is lifted to release the tightening, and the lead frame (11) in which the main part including the semiconductor element (13) is molded is taken out. After the resin burrs (25) are removed by punching and the external leads (14) are soldered, the tie bars (15) are cut off by stamping to separate the semiconductor devices into individual parts.

According to the configuration of the present invention described above, the resin (24) leaking from the gap between the dam block (19) and the lead (14) is stagnated in the resin retaining space (20), and the pressure is released. Since the resin burr (25) is cured in this state, the adhesion force of the resin burr (25) formed here can be made extremely small. Therefore, the resin burr (2) formed in the resin retaining space (20)
5) can be removed very easily in the post-process. On the other hand, the resin burrs hardened in the gap between the dam block (19) and the lead (14) are removed from the resin (2) in the cavity (17).
It cannot be easily removed because it hardens under pressure equal to or higher than 4). However, the area near the base of the lead (14) is not relevant to mounting electronic components, and no solder plating will be applied there. Highly reliable mounting is possible as long as it is attached below the vicinity of the tie bar (15). Therefore, the length of the dam block (19) is determined by focusing on the position of the leads (14) to be soldered during mounting.
The length should be such that it is unevenly distributed toward the cavity (17) from that position.

(G) Effects of the Invention As explained above, according to the present invention, the resin (24) is made to stagnate in the resin retaining space (20) and is cured in a state where the pressure is released. The resin burr (25) generated here has the advantage of weak adhesion and can be easily removed. Therefore, by removing the resin burr (25) generated in the resin retaining space (20), the lead (14) is removed.
) has the advantage of minimizing resin adhesion, preventing solder sticking, and providing electronic components that can be mounted with high reliability. In addition, since the resin burr (25) can be easily removed, there is also an advantage of greatly improving workability and reducing costs in the assembly process.
