発光ダイオードは、従来、2本の端子を有する単体の素
子として組立てられることが多い。このため、自動組立
、スクリーニングなどが難しがった。Light emitting diodes are conventionally often assembled as a single device with two terminals. This made automatic assembly and screening difficult.
第10図は、従来例に係る発光ダイオードの縦断面図で

などがある。This shows a resin molded light emitting diode 40. The light emitting diode 40 uses two vertical terminals 41 and 42,
A light emitting diode chip 43 is bonded onto one terminal, and this electrode and the other terminal are connected by wire bonding. It is then molded with transparent resin. The mold part 45 has terminals 41 and 42.
It has the function of fixing the chips, protecting the chips and wires, and focusing the light.
このような発光ダイオードは、スクリーニング工程を意
識した電極構造が考慮されていない為、スクリーニング
工程が煩労になる。Since such a light emitting diode does not have an electrode structure that takes into account the screening process, the screening process becomes troublesome.
第11図は、従来例に係る他の発光ダイオードの縦断分
解図である。FIG. 11 is a longitudinal exploded view of another conventional light emitting diode.

キャップ51をヘッダ48に蓋せ、融着しである。A light emitting diode chip 49 is bonded onto a metal header 48 having a vertical terminal 47, and the electrode of the chip 49 and another terminal (not connected to the header) are connected by wire bonding 50L and then a glass window. The attached metal cap 51 is placed on the header 48 and fused.
このような発光ダイオードは、単体のまま組立てるので
、組立を自動化するのが難しいし、スクリーニング工程
も煩労になる。Since such light emitting diodes are assembled as single units, it is difficult to automate the assembly, and the screening process is also troublesome.
スクリーニングというのは、素子その他の製品を通電状
態のまま数日〜数週間試験し、不良品か生じると、これ
を除去する工程をいう。Screening is a process in which devices and other products are tested for several days to several weeks while energized, and any defective products are removed.
素子その他の製品は、製造された時点で所望の性能条件

在的に、もともと故障−の原因を持っており、これが通
電試験により早く外へ現われたものである。Even if elements and other products satisfy desired performance conditions at the time of manufacture, they break down with use. The probability that a product will fail is not always constant over its lifetime. The failure rate is often high within several days to several weeks after manufacturing. This is called initial failure. Internally, there is a cause of failure from the beginning, and this is something that appears early in the energization test.
初期不良の現われた発光ダイオードは除かなければなら
ない。これがスクリーニングである。Light emitting diodes showing initial defects must be removed. This is screening.
第10図、第11図のような発光ダイオードは各素子が
スクリーニング前の工程では個々が電気的に分離されて
おり、スクリーニングのため、各素子ことに通電しなけ
ればならない。専用の治具や試験器具を多数必要とし、
手数もかかり、煩労な作業である。In the light emitting diodes shown in FIGS. 10 and 11, each element is electrically isolated from each other in the process before screening, and each element must be energized for screening. Requires a large number of specialized jigs and testing equipment,
This is a time-consuming and troublesome work.
本発明は、これらの欠点を克服し、組立作業の自動化、
スクリーニング作業の簡略化に最適で、しかも放熱効果
