【発明の詳細な説明】 〔発明の目的〕 （産業上の利用分野） 本発明は電子部品の金型樹脂成形法に関する。[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a mold resin molding method for electronic parts.
（従来の技術）
金型を用いた樹脂成形により基板上に搭載された電子部
品を封止する方法として、金属封止。(Prior art) Metal sealing is a method of sealing electronic components mounted on a board by resin molding using a mold.
セラミック封止、ガラス封脂、樹脂封止等の各種方法が
従来から用いられている。Various methods such as ceramic sealing, glass sealing, resin sealing, etc. have been used in the past.
このうち、特に高い信頼性を要求される場合やある種の
大容量パワートランジスタの封止を行う場合を除き、樹
脂封止による方法が一般的である。Among these methods, resin encapsulation is commonly used except in cases where particularly high reliability is required or when a certain type of large capacity power transistor is to be encapsulated.
このような樹脂封止による成形法の一例を第９図を参照
して説明する。An example of such a molding method using resin sealing will be explained with reference to FIG. 9.
この樹脂封止による成形法は、まず各種の集積回路等の
電子部品２１を、リードフレーム等の金属製の基板２０
上にハンダ付は法、ペースト法又は共晶法を用いて搭載
した後、この基板２０の両側に電極端子２２ａ、２２ｂ
を配置し、電子部品２１と電極端子２２ａ、２２ｂとの
間にそれぞれワイヤボンディングの手法により金線２３
ａ、２３ｂを接続する。In this molding method using resin sealing, electronic components 21 such as various integrated circuits are first placed on a metal substrate 20 such as a lead frame.
Electrode terminals 22a and 22b are mounted on both sides of this board 20 after being mounted using a soldering method, a paste method, or a eutectic method.
A gold wire 23 is placed between the electronic component 21 and the electrode terminals 22a and 22b by wire bonding.
Connect a and 23b.
そして、第９図に示すように前記基板２０．電子部品２
１．金線２３ａ、２３ｂと電極端子２２ａ。Then, as shown in FIG. 9, the substrate 20. Electronic parts 2
1. Gold wires 23a, 23b and electrode terminal 22a.
２２ｂの一部とを、金型を用いた樹脂封止の方法により
封止し、樹脂部２４を形成するようにしたものである。22b is sealed by a resin sealing method using a mold to form a resin portion 24.
このような成形法の場合、一対の金型の型締めの際にこ
れら金型間に挟持される電子部品２１を搭載した基板２
０には数トン程度の大きな圧力が加わるため、基板２０
が例えば銅合金、 ＦｅＮｉ合金等の金属製であれば十
分な型締めにより樹脂の流れを防止しつつ所望の成形品
を得ることができる。In the case of such a molding method, the substrate 2 on which the electronic component 21 is mounted is held between a pair of molds when the molds are clamped.
Since a large pressure of several tons is applied to the substrate 20
If it is made of metal such as copper alloy or FeNi alloy, the desired molded product can be obtained while preventing resin flow by sufficient mold clamping.
しかし、上述した成形法でセラミック類等の基板２０上
に搭載した電子部品２１を樹脂封止しようとすれば、金
型による圧力のためセラミック類の基板２０に割れや亀
裂が生じることになり、この結果、セラミック類等の基
板２０を用いた電子部品２１に対してはこの成形法を適
用できないという問題がある。However, if an attempt is made to resin-seal electronic components 21 mounted on a ceramic substrate 20 using the above-described molding method, cracks or cracks will occur in the ceramic substrate 20 due to pressure from the mold. As a result, there is a problem in that this molding method cannot be applied to electronic components 21 using a substrate 20 made of ceramic or the like.
また、この成形法は電子部品２１を外部環境から保護し
たりこの電子部品２１の作動時に生じる熱を外部に放熱

介しての電気信号の処理に限定され、わずかに樹脂部２
４に透明樹脂を用いて光信号の処理を行なうものが散見
される程度であった。In addition, this molding method is mainly aimed at protecting the electronic component 21 from the external environment and dissipating heat generated when the electronic component 21 is operated to the outside, and the substrate 20 and the electronic component 21 are sealed with the resin part 24. Therefore, the signal processing mode in the molded product is limited to the processing of electrical signals via the electrode terminals 22a and 22b, and the resin part 2 is slightly
There were only a few cases where optical signals were processed using transparent resin.
一方、金型を用いない成形法として、キャスティング、
ボッティング等の注型法、浸漬法１滴下法等が知られて
いる。これらの方法はいずれも基板の一部を電子部品か

熱信号等電気信号以外の信号処理も可能な成形品を得る
ことができるものの、成形後の樹脂の寸法精度や量産性
の点で十分なものが得られないという問題がある。On the other hand, casting,
Casting methods such as botting, dipping methods, single drop methods, etc. are known. Both of these methods allow parts of the board to be exposed outward from the electronic components, thereby allowing optical signals,
Although it is possible to obtain a molded product that is capable of processing signals other than electrical signals such as thermal signals, there is a problem in that the resin after molding cannot be obtained with sufficient dimensional accuracy or mass productivity.

基板１上に、一方の端部が前記電子部品２に接続され、
他方の端部が基板ｌの他方の端部近傍に至る電極Ｊｉ３
ａ、３ｂを形成する。First, as shown in FIGS. 1 and 2, electronic components 2 such as various integrated circuits are soldered onto a substrate 1 made of ceramic, for example, and from the center to the left side area in the figure.
It is mounted using a paste method or a eutectic method, and one end is connected to the electronic component 2 on this substrate 1,
Electrode Ji3 whose other end reaches near the other end of the substrate l
Form a and 3b.
次に第３図に示すように電子部品２を搭載し、かつ、電
極層３ａ、３ｂを形成した基板１を、−対の金型４ａ、
４ｂ間に配置する。Next, as shown in FIG. 3, the substrate 1 on which the electronic component 2 is mounted and on which the electrode layers 3a and 3b are formed is placed in a pair of molds 4a,
Place it between 4b.
前記金型４ａ、４ｂは、同図に示すようにお互いに相対
向する面に略対称形状の凹部４ｃ、４ｄを設けてこれら

ともに、前記凹部４ｃ、４ｄの一方の端部（型締部）側
に相対向配置に、且つ、両金型４ａ、４ｂの相対向する
面からそれぞれ若干突出する状態に一対のゴム製の弾性
体６ａ、６ｂを備えている。As shown in the figure, the molds 4a and 4b have substantially symmetrical recesses 4c and 4d on their opposing surfaces, and the space formed between them forms a resin injection part 5. A pair of rubber elastic bodies 6a are arranged opposite to each other on one end (mold clamping part) side of the recesses 4c and 4d, and slightly protrude from the opposing surfaces of both molds 4a and 4b. , 6b.
そして、第４図に示すように前記両弾性体５ａ。And, as shown in FIG. 4, both the elastic bodies 5a.
６ｂにより、基板１の中央部及び前記電極Ｎ ３ ａ
。6b, the central part of the substrate 1 and the electrode N 3 a

成形を行う。A predetermined pressing force is applied to both the molds 4a and 4b while holding the mold 3b from above and below, and the resin injection part 5 is heated to about 80 degrees Celsius in advance with the electronic component 2 facing inside the resin injection part 5. After preheating and injecting the low-viscosity resin, electronic parts 2.
Resin molding is performed on the outer periphery of a portion of the electrode layers 3a and 3b and a portion of the substrate 1.

b is deformed more than necessary, and as a result, after the molds 4a and 4b are released, the molded product 8 has unevenness on the side surface due to the deformation of the elastic bodies 5a and 5b as shown in FIG. 6, resulting in poor dimensional accuracy. As the condition worsens, the elastic body 6a is torn at the contact portion between one of the molds 4a and the elastic body 6a, as shown in section B in FIG. On the other hand, if the elastic bodies 5a and 6b have high hardness, the substrate l will be destroyed.
このため、弾性体５ａ、５ｂの硬度として例えばシェア
ーＤ３０程度のものを用いることが好ましい。For this reason, it is preferable to use a hardness of about Shear D30 for the elastic bodies 5a and 5b, for example.
また、これら弾性体６ａ、６ｂの耐熱性は高温の樹脂に
晒されることから、１５０ ’Ｃ以上の耐熱性を有する
ものも用いることが好ましい。Furthermore, since these elastic bodies 6a and 6b are exposed to high temperature resin, it is preferable to use those having a heat resistance of 150'C or more.
