Description

【0001】
【発明の属する技術分野】
本発明は、電子部品を回路基板に表面実装するための電子部品搭載用ケースおよびその形成方法に関する。
【0002】
【従来の技術】
コンピュータや携帯電話等の電子機器内に使われる電子部品は、本体の電子機器のコンパクト化に伴ってさらなる小型化が要求されているとともに、電子部品の精度、コストの低廉化、作業性の向上など、厳しい要求が続いている。
【0003】
コンピュータについていえば、プリント基板であるところのマザーボードに半田付けにて実装されるLSI(Large Scale Integrated Circuit)等の電子部品には、前記マザーボードに形成された配線パターンと電気的に接続される端子がケース(電子部品の外装)本体の外部に露出するようにして形成されている。例えば、LSIには、SOP(Small Out−line Package)といわれる、矩形状のケース本体にクランク型の端子が外向きに形成されていることを外形状の特徴とするケースがある。このSOPのケース本体から外向きに形成される端子は、マザーボード上における実装面積をケース本体の面積以上とする要因となるため、本体の電子機器のコンパクト化を考えれば改良の余地があった。そこで、端子をケースの内側に回り込むJ型の端子として、小型化を図ったSOJ(Small Out−line J−lead)といわれるLSIも開発されている。
【0004】
携帯電話についても、その実装面積を小さくすべく、例えば、送受信時の無線周波を作るVCO(Voltage Controled Oscillator)は、グランド端子、電源電圧入力端子、制御電圧入力端子、周波数出力端子などの端子のうち少なくとも1つを具備しており、前記端子は略方形状とされたケースの側面等の表面に、ケース本体表面と略面一にして露出するように形成されている。
【0005】
このように、従来から様々な工夫がなされてきたが、半田付けによってプリント基板に実装される電子部品の場合は、コンパクトに形成されたケースの表面に、その本体表面と略面一にして露出する端子が形成された電子部品が、実装面積を小さくするという目的においては最も優れたものとなる。
【0006】
そして、例えば、前記VCOにおいて、ケースの表面にグランド端子やそれ以外の出入力端子(独立端子)を形成する場合、樹脂材等からなるケースの表面に、半田めっき法や印刷法により端子を形成し、電気回路を構成しておき、チップ部品を後工程で搭載させてVCOをモジュールとして完成させるのが従来の一般的な方法であった。

【0008】
【発明が解決しようとする課題】
しかしながら、この従来の方法は、ケースの表面(特に、側面)に端子を形成する作業はとても困難であるため非効率的であり、コストも嵩むといった欠点を有する。
【0009】
そこで、本発明は、電子部品の小型化の要請に応え、しかも、表面実装時の接続安定性に優れた電子部品搭載用ケースと、簡単かつ安価にケースの表面にグランド端子とそれ以外の端子を形成することができる電子部品搭載用ケースの形成方法を提供することを目的とする。
【0010】
【課題を解決するための手段】
前述した目的を達成するため、本発明の電子部品搭載用ケースは、電子部品を回路基板に表面実装するための電子部品搭載用ケースであって、成形樹脂材により形成されたケース本体の側面に、一方の端部を前記ケース本体の上面に当該上面と略面一にして露出させ、他方の端部を前記ケース本体の底面に当該底面と略面一にして露出させるとともに端子基板部に連結させた少なくとも1本のコモン端子、および/または、一方の端部を前記ケース本体の上面に当該上面と略面一にして露出させ、他方の端部を前記ケース本体の底面に当該底面と略面一にして露出させた少なくとも1本の独立端子を有することを特徴とする。
【0011】
また、前記ケース本体の上面中央部に、搭載する電子部品の一部を収納可能とされた空間部を有することを特徴とする。
【0012】
この電子部品搭載用ケースは、当該電子部品搭載用ケースの上面に形成された空間部に、搭載する電子部品の一部を収納しつつ前記電子部品の接続端子を当該電子部品搭載用ケースの上面に露出させて形成された、対応するグランド端子などのコモン端子および/または独立端子に接続して1つのモジュールを形成した後に、当該モジュールを回路基板の所定位置に配置し、前記回路基板に形成された端子と、前記電子部品搭載用ケースの端子とを電気的に接続させるようにして用いる。
【0013】
そして、本発明の電子部品搭載用ケースは、そのケース本体の表面と略面一にして露出する端子が形成されているので、はんだ付けによって電子部品を実装する場合に、その実装面積を最小とすることができる。しかも、電子部品搭載用ケースの側面にライン状に所定の面積で配置されることとなる端子は、端子前記電子部品を実装する回路基板に形成された端子とのはんだ付けをより確実なものとすることができ、表面実装時の接続安定性を優れたものとすることができる。さらに、前記ケース本体の上面中央部に形成された空間部に搭載する電子部品の一部を収納することにより、前記電子部品の一部を当該ケース本体によってガードすることができるとともに、当該電子部品搭載用ケースを用いたモジュール自体の高さ寸法を小さくすることが可能となる。
【0014】
また、本発明の電子部品搭載用ケースの形成方法は、帯状とされた導電性板材から、前記導電性板材の長手方向の両側部と該両側部間を連結する連結部からなるキャリア部、前記キャリア部に連接部により接続された端子基板部、前記端子基板部から延在する少なくとも1つの第1端子片、および、前記キャリア部に連結され前記端子基板部の配設方向と反対方向に延在する少なくとも1つの第2端子片を備えたターミナルを打抜き形成するターミナル形成工程、前記第1端子片を前記端子基板部に連接するコモン端子として曲げ形成し、前記第2端子片を前記キャリア部に交差させるようにして前記端子基板部の配設方向に折り曲げるとともに、前記端子基板部から独立した独立端子として曲げ形成してケース枠を形成するケース枠形成工程、樹脂材のインサート形成により前記コモン端子および独立端子を一体にしてケース本体を形成するケース本体形成工程、および、前記電子部品搭載用ケース本体から突出する前記ターミナルの各部分を切断して単体の電子部品搭載用ケースを形成する切断分離工程からなることを特徴とする。
【0015】
そして、前記ケース枠形成工程においては、前記第1端子片は、その先端部を前記導電性板材の一表面側に略垂直に折り曲げて当該電子部品搭載用ケースの電子部品搭載面に露出する端子部とし、前記端子基板部との連結部位の近傍を当該導電性板材の前記一表面側に略垂直に折り曲げて当該電子部品搭載用ケースの側面に露出する端子部として前記コモン端子を形成し、前記第2端子片は、その先端部を前記導電性板材の前記一表面側に略垂直に折り曲げて当該電子部品搭載用ケースの電子部品搭載面に露出する端子部とし、その中間部を当該導電性板材の他表面側に略垂直に折り曲げて当該電子部品搭載用ケースの側面に露出する端子部とし、さらに、その基端部を折り畳んで、前記電子部品搭載用ケースの電子部品搭載面に露出する端子部及び側面に露出する端子部を前記端子基板部の近傍に配置して独立端子を形成することを特徴とする。
【0016】
また、前記電子部品搭載用ケース本体形成工程においては、前記ケース枠形成工程で形成されたケース枠を、前記ケース枠の前記コモン端子および独立端子の外表面を当該電子部品搭載用ケースの表面に露出させるように成形樹脂材を注入可能とされたキャビティが形成された下金型と上金型とからなる一対の金型に配置するか、あるいは、前記ケース枠の前記グランド端子および独立端子の外表面を当該電子部品搭載用ケースの表面に露出させ、かつ、当該電子部品搭載用ケースの上面中央に当該電子部品搭載用ケース上面に搭載される電子部品の一部を収容可能とする空間部を形成するように成形樹脂材を注入可能とされたキャビティが形成された下金型と上金型とからなる一対の金型に配置して、前記キャビティに成形樹脂材を流し込んで前記各端子を当該電子部品搭載用ケースの所定位置に固定してケース本体を得ることを特徴とする。
【0017】
これらの特徴を有する本発明の電子部品搭載用ケースの形成方法によれば、前述したような、ケース本体の側面に、電子部品側の端部を当該ケース本体の上面に当該上面と略面一にして露出させ、かつ、基板側の端部を当該ケース本体の底面に当該底面と略面一にして露出させた端子基板部に連結させた少なくとも1本のコモン端子、および、電子部品側の端部を当該ケース本体の上面に当該上面と略面一にして露出させ、かつ、基板側の端部を当該ケース本体の底面に当該底面と略面一にして露出させた少なくとも1本の独立端子を有することを特徴とする前記電子部品搭載用ケースを簡単に形成することができる。
【0018】
さらに、前記金属板の当該電子部品搭載用ケースの表面に露出することとなる部分にのみメッキ加工を施せば、コスト削減を実効できる。
【0019】
【発明の実施の形態】
以下、本発明の電子部品搭載用ケースの形成方法と、この形成方法により形成された電子部品搭載用ケースの実施形態を、図1乃至図8に基づいて説明する。
【0020】
電子部品搭載用ケースを形成する際には、まず、プレス加工により前記電子部品搭載用ケース1のケース枠11を形成するためのターミナル3を帯状の導電性板材2から打抜き形成する。
【0021】
図1は、本実施形態において使用するターミナル3の形状を示す平面図である。
【0022】
この図に示すように、本実施形態の前記ターミナル3は、前記導電性板材2の長手方向の両側部4a、4bと該両側部4a、4b間を連結する連結部4c,4dからなるキャリア部4を備えており、前記両側部4a、4bと2本の連結部4c,4dにより囲繞された略長方形状の空間内には、電子部品搭載用ケース1の底面に露出して、コモン端子としてのグランド端子5の端子基板部6を構成することとなる長方形状の板部材が2本の連接部7により前記キャリア部4に連結されている。
【0023】
また、前記端子基板部6には、電子部品搭載用ケース1の外表面に露出して、前記グランド端子5の端子部を構成することとなる金属片(以下、第1端子片)9が連結されて延在している。
【0024】
詳しくは、第1端子片9は、前記端子基板部6の図1中の右側辺6aには中央部と前記右側辺の一端部に1本の計2本、また、前記端子基板部6の上端辺6b、左側辺6cおよび下端辺6dには、それぞれの中央部に1本ずつ連結されている。
【0025】
さらに、本実施形態において、前記連結部4c、4dには、電子部品搭載用ケース1の外表面に露出して独立端子10の端子部を構成することとなる金属片(以下、第2端子片)13が前記端子基板部6の配設方向と反対方向に延在するようにして連結されている。
【0026】
詳しくは、本実施形態においては、前記端子基板部6の前記右側辺6a側に配設された前記連結部4cには、ケース枠11を形成したときに前記右側辺6aの他端部近傍に位置する1本の第2端子片13が前記端子基板部6の配設方向と反対方向に延在するようにして形成されている。また、前記左側辺6c側に配設された前記連結部4dには、ケース枠11を形成したときに前記左側辺6cの両端部近傍にそれぞれ位置する2本の第2端子片13が前記端子基板部6の配設方向と反対方向に延在するようにして形成されている。
【0027】
なお、本実施形態において、前記導電性板材2の当該電子部品搭載用ケース1の表面に露出することとなる部分にはメッキ加工が施されている。このように、メッキ加工を施す部分を限定することにより、コスト削減を実効できる。
【0028】
次に、このような形状とされたターミナル3から、ケース枠11を形成する。
【0029】
本実施形態においては、金型プレス加工により、前記ターミナル3の各第1端子片9を、図2に示すように、その先端部を前記ターミナル3の一表面である内面側に略垂直に折り曲げて前記電子部品搭載用ケース1の電子部品搭載面に露出する端子部5aを形成し、前記端子基板部6との連結箇所の近傍を前記ターミナル3の前記内面側に略垂直に折り曲げて、当該電子部品搭載用ケース1の側面に露出する端子部5bを形成し、コモン端子としてのグランド端子5とする。また、前記第2端子片13を、図3に示すように、その先端部を前記ターミナル3の前記内面側に略垂直に折り曲げて、前記電子部品搭載用ケース1の電子部品搭載面に露出する端子部10aを形成し、その中間部を前記ターミナル3の他表面である外面側に略垂直に折り曲げて、前記電子部品搭載用ケース1の側面に露出する端子部10bを形成する。さらに、その基端部を前記ターミナル3の内面側に折り畳んで、前記電子部品搭載用ケース1の電子部品搭載面に露出する端子部10a及び側面に露出する端子部10bを前記端子基板部6の辺6a,6cの近傍に配置し、独立端子10とする。このとき、第2端子片13の前記電子部品搭載用ケース1の側面に露出する端子部10bを折り曲げ形成する際の折り曲げ部分(前記第2端子片13の中間部の折り曲げ箇所)が、当該電子部品搭載用ケース1の底面に露出するようにして折り曲げる。
【0030】
このようにして、図4および図5に示すような、5つのグランド端子5と3つの独立端子10とを有する電子部品搭載用ケース1のケース枠11を前記ターミナル3上に形成する。
【0031】
続いて、前記ターミナル3を、図示しない下金型と上金型とからなる一対の金型にアライメントして配置し、樹脂材のインサート形成により前記グランド端子5および独立端子10を一体にしてケース本体16を形成する。
【0032】
前記金型内には、型締めした状態において前記ケース枠11の各端子5,10を前記電子部品搭載用ケース1の外表面に露出させ、かつ、前記電子部品搭載用ケース1の上面中央に前記電子部品搭載用ケース1の上面に搭載される電子部品20の一部を収容可能とする空間部14を形成するように成形樹脂材15を注入可能とされたキャビティ(図示せず)が形成されている。
【0033】
そして、前記一対の金型を型締めして、前記キャビティに成形樹脂材15を流し込み、図6に示すように前記各端子5,10を前記電子部品搭載用ケース1の所定位置に固定して電子部品搭載用ケース1のケース本体16を得る。
【0034】
その後、前記各第2端子片13の前記ケース本体16から突出する部分を切断するとともに、前記ケース本体16を前記ターミナル3に繋ぐ連接部7を切断分離して、図7に示すような前記電子部品搭載用ケース1を形成する。
【0035】
このようにして形成された電子部品搭載用ケース1は、図8に示すように、成形樹脂材15により外形状略方形に形成されたケース本体16の上面中央部に、搭載する電子部品20の一部を収納可能とされた空間部14を有し、前記ケース本体16の側面には、一方の端部を前記ケース本体16の上面に当該上面と略面一にして露出させて電子部品20の端子21と電気的に接続させるための端子部5aとし、他方の端部を前記ケース本体16の底面に当該底面と略面一にして露出させるととともに、この他方の端部をグランド端子5の端子基板部6に連結させて前記電子部品20を実装する回路基板22の端子23と電気的に接続させる5つのグランド端子5の端子部5bと、一方の端部を前記ケース本体16の上面に当該上面と略面一にして露出させて電子部品20の端子21と電気的に接続させるための端子部10aとし、他方の端部を前記ケース本体16の底面に当該底面と略面一にして露出させて前記電子部品20を実装する回路基板22の端子23と電気的に接続させる3つの独立端子10の端子部10bを露出させたものとなる。
【0036】
図8に示す前記電子部品搭載用ケース1を用いた電子部品の実装の具体例においては、チップ基板24に素子25をワイヤボンディング法(図中26はワイヤを示す)により電気的に接続し、さらに、シリコン樹脂等の封止材27によりこれら素子25等が封止された電子部品20の前記素子25等を電子部品搭載用ケース1の空間部14に収納しつつ、前記チップ基板24に形成された回路パターン24aの端子21を、前記電子部品搭載用ケース1の上面に露出させて形成された、対応するグランド端子5の端子部5aおよび独立端子10の端子部10aにワイヤボンディング法やはんだ付け等により接続して、1つのモジュール30を形成する。なお、図8のモジュール30は、前記電子部品搭載用ケース1の上方に、前記電子部品20を覆って保護するガードケース(上蓋)31を配設している。
【0037】
そして、前記モジュール30をマザーボードとしての回路基板22の所定位置に配置し、前記回路基板22に形成された回路パターン22aの端子23と、前記電子部品搭載用ケース1の底面および側面に露出する対応するグランド端子5および独立端子10とをはんだ付け(図中、32ははんだを示す)により電気的に接続させるようにして用いる。
【0038】
その際、本実施形態の電子部品搭載用ケース1は、そのケース本体16の側面と略面一にして露出するようにして各端子5,10が形成されているので、はんだ付けによって電子部品20を実装する場合に、その実装面積を最小とすることができる。しかも、電子部品搭載用ケース1の側面にライン状に所定の面積で配置されることとなる各端子5(5b)、10(10b)は、前記電子部品20を実装する回路基板22に形成された回路パターン22aの接続端子23とのはんだ付けの接続面を広く確保することができるので、その電気的接続が確実なものとなり、また、各々の独立端子10間、および独立端子10とグランド端子5間は、前記電子部品搭載用ケース1のケース本体16を構成する形成樹脂材15により確実に電気的に遮断されるのでリークの問題もなく、表面実装時の接続安定性を優れたものとすることができる。また、前記ケース本体16の上面中央部に形成された空間部14に、電子部品20の突出部分を収納することにより、前記電子部品20の突出部分を当該ケース本体16によってガードすることができ、さらには、モジュール30自体の高さ寸法も小さくすることが可能となる。
【0039】
なお、本発明は、前述した実施の形態に限定されるものではなく、必要に応じて種々の変更が可能である。例えば、前記キャビティは、前記実施形態において前記電子部品搭載用ケースの上面中央に形成した、当該電子部品搭載用ケース上面に搭載される電子部品の一部を収容可能とする空間部を形成しないもの、つまり、前記ケース枠の前記コモン端子および独立端子の外表面を当該電子部品搭載用ケースの表面に露出させるように成形樹脂材を注入可能とされたものであってもよい。また、電子部品搭載用ケースに配設する端子の数は、前記実施形態の配設数にかぎるものではない。さらに、前記実施形態においては、前記第2端子片はその基端部を前記ターミナルの一表面側としての内面側に折り畳んだが、逆に、外面側に折り畳むようにしてもよい。またさらに、前記電子部品搭載用ケースを構成するケース本体を前記ターミナルから切断分離させるタイミングは、前記ケース本体の上面に電子部品を搭載した後であってもよい。
【0040】
【発明の効果】
以上説明したように、本発明の電子部品搭載用ケースによれば、電子部品の小型化の要請に応え、しかも、表面実装時の接続安定性に優れた電子部品搭載用ケースを提供することができる。
【0041】
また、本発明の電子部品搭載用ケースの形成方法によれば、前述の効果を有する電子部品搭載用ケースを簡単かつ安価に形成することができる。

In a computer, electronic components such as an LSI (Large Scale Integrated Circuit) mounted on a motherboard, which is a printed circuit board, by soldering, have terminals electrically connected to a wiring pattern formed on the motherboard. Are formed so as to be exposed to the outside of the case (exterior of the electronic component) main body. For example, in an LSI, there is a case called an SOP (Small Out-line Package), which is characterized in that a crank-shaped terminal is formed outward in a rectangular case main body and has an outer shape. The terminals formed outwardly from the case body of the SOP cause the mounting area on the motherboard to be larger than the area of the case body. Therefore, there is room for improvement in terms of downsizing the electronic device of the body. Accordingly, as a J-type terminal in which the terminal is wrapped around the inside of the case, an LSI called SOJ (Small Out-line J-lead) has been developed which is reduced in size.
[0004]
In order to reduce the mounting area of a mobile phone, for example, a VCO (Voltage Controlled Oscillator) that generates a radio frequency at the time of transmission / reception includes terminals such as a ground terminal, a power supply voltage input terminal, a control voltage input terminal, and a frequency output terminal. At least one of the terminals is provided, and the terminal is formed on a surface such as a side surface of a substantially rectangular case so as to be exposed substantially flush with the surface of the case body.
[0005]
As described above, various contrivances have been made in the past, but in the case of an electronic component mounted on a printed circuit board by soldering, the electronic component is exposed on the surface of the compact case almost flush with the main body surface. An electronic component having terminals formed thereon is most excellent for the purpose of reducing the mounting area.
[0006]
For example, in the VCO, when a ground terminal and other input / output terminals (independent terminals) are formed on the surface of the case, the terminals are formed on the surface of the case made of a resin material or the like by a solder plating method or a printing method. In a conventional general method, an electric circuit is formed, and chip components are mounted in a later process to complete the VCO as a module.
