Description

電子部品、その製造方法及び製造装置Electronic component, manufacturing method and manufacturing apparatus
　本発明は、電子部品、その製造装置及び製造方法に関し、より詳細には電磁シールド板又は放熱板として機能する板状部材と配線基板と封止性樹脂とを有する電子部品、その製造装置及び製造方法に関する。 The present invention relates to an electronic component, a manufacturing apparatus and a manufacturing method thereof, and more specifically, an electronic component having a plate-like member functioning as an electromagnetic shield plate or a heat sink, a wiring board, and a sealing resin, a manufacturing apparatus and a manufacturing method thereof Regarding the method.
　従来、電子部品は携帯電話機等の通信機器等における高周波回路等に用いられている。この電子部品の製造方法は、次の３つの工程を有する。まず、信号配線パターンやグラウンド配線パターン等の表面配線パターンを有する配線基板の上面に、IC（Integrated Circuit）等の半導体素子等の電子素子を載置させる工程である。次に、電子素子の上面に設けられている接続電極と表面配線パターンとを、金属細線を介して電気的に接続する工程である。次に、絶縁性を有する封止樹脂によって電子素子を被覆する工程である。 Conventionally, electronic components are used in high-frequency circuits and the like in communication devices such as mobile phones. This electronic component manufacturing method has the following three steps. First, an electronic element such as a semiconductor element such as an IC (Integrated Circuit) is placed on the upper surface of a wiring board having a surface wiring pattern such as a signal wiring pattern or a ground wiring pattern. Next, it is a step of electrically connecting the connection electrode provided on the upper surface of the electronic element and the surface wiring pattern via a fine metal wire. Next, the electronic element is covered with an insulating sealing resin.
　従来の電子部品は、携帯電話などの通信機器内に組み込まれた後に、電子部品の周囲に配置される他の電子部品からの電磁的な影響によって、誤動作するおそれを有する。特に、電子部品が高周波回路に用いられる際に誤作動する可能性が高い。そこで、誤作動するおそれを解消するために、次の工程を有する電子部品の製造方法が提案されている(特許文献１参照)。まず配線基板上に金属ポストを形成する工程である。次に、チップ部品（電子素子）の上面に設けられている電極端子（接続電極）と基板上のパッド部（表面配線パターン）とを、金属ワイヤ（金属細線）を介して電気的に接続する工程である。次に、金属ポストの上面に、樹脂封止の際に用いる成形型よりも柔らかい材料からなる金属ワイヤを形成する工程である。次に成形型を金属ワイヤに接触させて型締めした状態で、チップ部品及び金属ポストを封止樹脂によって樹脂封止する工程である。次に、前の工程で得られた樹脂封止後の構造体を、ダイサー等により、各デバイス単位に切断して個片化する工程である。次に、個片化された構造体に対し、金属製シールドケースを装着する工程である。この工程によって、封止樹脂から露出した金属ワイヤと金属製シールドケースを電気的に接続する。 Conventional electronic components may malfunction due to electromagnetic influences from other electronic components arranged around the electronic components after being incorporated in a communication device such as a mobile phone. In particular, there is a high possibility of malfunction when electronic components are used in high-frequency circuits. Thus, in order to eliminate the possibility of malfunction, an electronic component manufacturing method having the following steps has been proposed (see Patent Document 1). First, a metal post is formed on a wiring board. Next, an electrode terminal (connection electrode) provided on the upper surface of the chip component (electronic element) and a pad portion (surface wiring pattern) on the substrate are electrically connected via a metal wire (metal thin wire). It is a process. Next, it is a step of forming a metal wire made of a material softer than the mold used for resin sealing on the upper surface of the metal post. Next, in a state where the mold is brought into contact with the metal wire and clamped, the chip component and the metal post are resin-sealed with a sealing resin. Next, the resin-encapsulated structure obtained in the previous step is a step of cutting into individual devices by dicer or the like and dividing into individual devices. Next, a metal shield case is attached to the separated structure. By this step, the metal wire exposed from the sealing resin and the metal shield case are electrically connected.

　本実施例に係る電子部品１の製造方法を説明する。電子部品１は、図２（ａ）に示す少なくとも電子素子３と導電性部材６とが装着された実装済基板１３を樹脂封止することによって製造される。図２（ｂ）に示す樹脂封止用の成形型１４は、上型１５と下型１６とを有する。上型１５は、実装済基板１３を固定する固定具（図示せず）又は吸着機構（図示せず）の少なくとも一方を有する。下型１６は、キャビティ１７を有する。キャビティ１７内の底面の隅には、キャビティ１７に対して板状部材５を位置合わせするための突起１８を設ける。 A method for manufacturing the electronic component 1 according to the present embodiment will be described. The electronic component 1 is manufactured by resin-sealing a mounted substrate 13 on which at least the electronic element 3 and the conductive member 6 shown in FIG. A molding die 14 for resin sealing shown in FIG. 2B has an upper die 15 and a lower die 16.

As the cream solder 20, it is preferable to employ a material having a melting point lower than the curing temperature (for example, about 180 ° C.) in resin molding, in other words, the low melting point cream solder 20. As a result, the cream solder 20 is melted at the curing temperature. Therefore, the plate-like member 5 to which the cream solder 20 is applied is in a state where the conductive member 6 can be joined by being placed in the molding die 14 heated to about 180 ° C. in advance.

The cavity 17 and the plate member 5 are aligned by the notch 19 (see FIG. 2A), and the plate member 5 is arranged.
　次に、図３（ａ）に示すように、キャビティ１７（図３（ｃ）参照）の内底面に配置した板状部材５を覆うようにして、常温において液状である絶縁性の液状樹脂２１（流動性樹脂）を注入する。液状樹脂２１として、例えば熱硬化性樹脂を使用する。 Next, as shown in FIG. 3A, an insulating liquid resin 21 that is liquid at room temperature so as to cover the plate-like member 5 disposed on the inner bottom surface of the cavity 17 (see FIG. 3C). Inject (flowable resin). As the liquid resin 21, for example, a thermosetting resin is used.
　次に、図３（ａ）に示された状態から図３（ｂ）に示されるように、上型１５と下型１６とを型締めする。このことによって、最初に、実装済基板１３の主面９に装着された導電性部材６を、キャビティ１７に注入された液状樹脂２１に侵漬する（漬ける）。次に、実装済基板１３の主面２０における電子素子３，ボンディングパッド７、＋電源パターン（図示なし）、グラウンド配線パターン８、金属細線１１、及び、実装済基板１３の主面を、液状樹脂２１に浸漬する（漬ける）。最後に、導電性部材６を板状部材５に接触させる。型締めした状態を一定時間（少なくとも２０秒以上）保つ。この間、液状樹脂２１を加圧しながら下型１６に設けられたヒータ（図示なし）を使用して、所定の硬化温度によって液状樹脂２１を加熱する。このことにより、図３（ａ）、（ｂ）に示すように、液状樹脂２１を硬化させて硬化樹脂からなる封止樹脂４を成形する。 Next, the upper die 15 and the lower die 16 are clamped from the state shown in FIG. 3A as shown in FIG. 3B. As a result, first, the conductive member 6 mounted on the main surface 9 of the mounted substrate 13 is immersed (immersed) in the liquid resin 21 injected into the cavity 17. Next, the electronic element 3 on the main surface 20 of the mounted substrate 13, the bonding pad 7, the + power supply pattern (not shown), the ground wiring pattern 8, the fine metal wires 11, and the main surface of the mounted substrate 13 are made of liquid resin. Immerse in 21 (soak). Finally, the conductive member 6 is brought into contact with the plate member 5. Hold the clamped state for a certain time (at least 20 seconds). During this time, the liquid resin 21 is heated at a predetermined curing temperature using a heater (not shown) provided in the lower mold 16 while pressurizing the liquid resin 21. As a result, as shown in FIGS. 3A and 3B, the liquid resin 21 is cured to form the sealing resin 4 made of the cured resin.
　次に、図３（ｃ）に示すように、上型１５と下型１６とを型開きする。このことによって下型１６と成形された封止樹脂４を有する封止済基板２２とを分離する。封止済基板２２が冷却される過程において、溶融したクリーム半田２０が硬化する。ここまでの工程によって、封止済基板２２からなる電子部品１を完成させる。 Next, as shown in FIG. 3C, the upper mold 15 and the lower mold 16 are opened. Thus, the lower mold 16 and the sealed substrate 22 having the molded sealing resin 4 are separated. In the process in which the sealed substrate 22 is cooled, the melted cream solder 20 is cured. The electronic component 1 composed of the sealed substrate 22 is completed through the steps so far.
　本実施例によれば、導電性部材６が接合する板状部材５の接合面にクリーム半田２０を塗布する。下型１６に設けられたヒータ（図示なし）を使用して、液状樹脂２１を加熱させて硬化させる工程において、クリーム半田２０を加熱してクリーム半田２０を溶融させる。このことにより、溶融したクリーム半田２０が導電性部材６の端面（図では下面）とその端面の周囲の側面とに存在する状態において、板状部材５に導電性部材６を確実に接触させる。板状部材５と導電性部材６とが接触した状態において、液状樹脂２１を硬化させる。電子部品１が冷却される過程において溶融したクリーム半田２０が硬化する。したがって、導電性部材６と既に硬化した状態にあるクリーム半田１２とクリーム半田２０が硬化した半田とによって板状部材５とグラウンド配線パターン８とを確実に電気的に接続することができる。言い換えれば、液状樹脂２１が硬化する際の圧縮応力によって押圧されてたわんだ（変形した）導電性部材６が板状部材５に接触して、電子部品１が冷却される過程において溶融したクリーム半田２０を硬化させる。したがって、板状部材５とグラウンド配線パターン８とをいっそう確実に電気的に接続することができる。 According to the present embodiment, the cream solder 20 is applied to the joining surface of the plate-like member 5 to which the conductive member 6 is joined. In the process of heating and curing the liquid resin 21 using a heater (not shown) provided in the lower mold 16, the cream solder 20 is heated to melt the cream solder 20. This ensures that the conductive member 6 is brought into contact with the plate-like member 5 in a state where the melted cream solder 20 exists on the end surface (lower surface in the drawing) of the conductive member 6 and the side surface around the end surface. In a state where the plate-like member 5 and the conductive member 6 are in contact, the liquid resin 21 is cured. In the process in which the electronic component 1 is cooled, the melted cream solder 20 is cured. Therefore, the plate-like member 5 and the ground wiring pattern 8 can be reliably electrically connected by the conductive member 6 and the solder cream 12 that has already been cured and the solder that the cream solder 20 has cured. In other words, the cream solder melted in the process in which the conductive member 6 bent (deformed) pressed by the compressive stress when the liquid resin 21 is cured contacts the plate-like member 5 and the electronic component 1 is cooled. 20 is cured. Therefore, the plate-like member 5 and the ground wiring pattern 8 can be more reliably electrically connected.
　クリーム半田１２は、硬化温度よりも高い融点を有する。液状樹脂２１を加熱させて硬化させる工程以降の工程においてクリーム半田１２は硬化した状態を維持するので、導電性部材６が固定された状態が維持される。したがって、導電性部材６がずれることが防止されるので、板状部材５とグラウンド配線パターン８とをいっそう確実に電気的に接続することができる。 Cream solder 12 has a melting point higher than the curing temperature. Since the cream solder 12 maintains the cured state in the steps after the step of heating and curing the liquid resin 21, the state where the conductive member 6 is fixed is maintained. Therefore, since the conductive member 6 is prevented from being displaced, the plate-like member 5 and the ground wiring pattern 8 can be electrically connected more reliably.
　本実施例によれば、樹脂封止する工程において、板状部材５とグラウンド配線パターン８との電気的な接続と、板状部材５の固定とを並行して行う。したがって、電子部品１を製造する際の生産性が向上する。特に、板状部材５の形状を箱状にした場合には、電磁波を良好に遮蔽する特性と良好な放熱性とを有する電子部品１が得られる。本実施例において、導電性部材６と板状部材５とは、それぞれ導電性を有する。この場合には、板状部材５は、電磁遮蔽機能を有する機能部材である。 According to the present embodiment, in the resin sealing step, the electrical connection between the plate member 5 and the ground wiring pattern 8 and the fixing of the plate member 5 are performed in parallel. Therefore, productivity when manufacturing the electronic component 1 is improved. In particular, when the shape of the plate-like member 5 is a box shape, the electronic component 1 having a property of shielding electromagnetic waves well and a good heat dissipation property can be obtained. In the present embodiment, the conductive member 6 and the plate-like member 5 each have conductivity. In this case, the plate-like member 5 is a functional member having an electromagnetic shielding function.

Resin sealing is performed in a state in which these shapes bite into the surface of the plate-like member 5. Thereby, the plate-like member 5 and the conductive member 6 can be electrically connected without interposing the cream solder 20 between the plate-like member 5 and the conductive member 6.
