Description

【０００１】
【発明の属する技術分野】
本発明は、例えばＱＦＰ、ＳＯＰ等の表面実装型電子部品を収納する電子部品用ソフトトレイに関し、特に運搬、輸送時における外部からの衝撃を吸収、或いは緩和可能な電子部品用ソフトトレイに関する。
【０００２】
【従来の技術】
近年、電子機器等の小型、薄型化に伴って、これに用いられる電子部品、例えばＱＦＰ（ＱｕａｄＦｌａｔ−ＬｅａｄｅｄＰａｃｋｅｇｅ）、ＳＯＰ（ＳｍａｌｌＯｕｔｌｉｎｅＰａｃｋｅｇｅ）等のフラットパックタイプの表面実装部品では、パッケージの横側に突出された多数のリードは、微細で、且つ微小な間隔で配置されている。したがって、このような表面実装部品を搬送したり、輸送したりする場合、リードの損傷のみならず、リードの変形及び折損が発生しないように留意をする必要がある。
【０００３】
そのため、このような電子部品の運搬や、搬送に際しては、図１３乃至図1６に示すような電子部品用ソフトトレイが用いられている。
【０００４】
即ち、図１３乃至図１６に示すように、従来の電子部品用ソフトトレイ１０１は、下側トレイ１０２と上側トレイ１０３とからなり、これらのトレイ１０２，１０３は、例えばポリエチレンテレフタレートフィルム（一般に、ＰＥＴフィルムと称される）を真空成形することにより形成される。
【０００５】
このトレイ１０２、１０３は、平面形状が矩形の平坦部１０４の中央部に、表面実装部品２００の厚みの半分を収納する凹部からなるポケット１０５が形成され、前記平坦部１０４の各辺には、前記ポケット１０５における凹部の突出方向と同じ方向に緩衝用のスカート部１０８ａ、１０８ｂ、１０８ｃ、１０８ｄが形成されている。各スカート部１０８ａ、１０８ｂ、１０８ｃ、１０８ｄは、前記平坦部１０４と略垂直で、且つ前記ポケット１０５における凹部の深さ以上の長さに形成されている。
【０００６】
そして、この下側トレイ１０２のポケット１０５に電子部品２００の下半分を収納し、且つ前記上側トレイ１０３をポケット１０５が下向きになるように反転させて、前記下側トレイ１０２に被せ、前記上側トレイ１０３のポケット１０５に電子部品２００の上半分を収納させて、前記上、下側トレイ１０２、１０３を一体化させ、図１６に示すように、電子部品用ソフトトレイ１０１を包装ケース（カートン）１２０内に詰めて輸送或いは搬送を行っている。
【０００７】
【発明が解決しようとする課題】
しかし、このような電子部品用ソフトトレイでは、次のような問題がある。即ち、運送、或いは搬送の途中で、例えば落下して上下方向（紙面上で、上下）から衝撃が加わった場合には、平坦部周辺とスカート部の変形により、その緩衝は吸収、或いは緩和される。しかし、横方向（紙面で、前後左右）から衝撃が加わった場合には、図１７に示すように、平坦部１０４とスカート部１０５とが連結した境界角部Ａが構造上強度あり、変形し難いため、その衝撃は吸収、或いは緩和されず、その衝撃により表面実装品本体、及びリードが、損傷、変形或いは折損するといった問題がある。
【０００８】
本発明は、上記課題に鑑みなされたもので、目的とするところは、横方向からの衝撃を吸収、或いは緩和して電子部品に損傷を与えないような電子部品用ソフトトレイを提供することにある。
【０００９】
【課題を解決するための手段】
上記目的を達成するために、第１の発明に係わる電子部品用ソフトトレイでは、平坦部と、前記平坦部の中央部に形成され、且つ表面実装の電子部品の高さ方向を前記平坦部にほぼ垂直に収納するための凹部からなるポケットと、前記平坦部の周端部から前記ポケットの突出方向で、且つポケット部の深さを超えた位置まで延びるスカート部と、前記平坦部と前記スカート部との境界角部から離間した前記スカート部の外側面にあって、前記スカート部の対向個所に、それぞれ外側方に突設された緩衝手段とを具備してなることを特徴としている。

【００１２】
更に、上記目的を達成するために、第４の発明に係わる電子部品用ソフトトレイでは、平面形状が四角形の平坦部と、前記平坦部の中央部に形成され、且つ電子部品を収納するための凹部からなるポケットと、前記平坦部の各辺から前記ポケットの突出方向に当該ポケットの深さを超えた位置まで延び、且つ互いに連接された平面形状が四角形のスカート部と、前記平坦部と前記スカート部との境界角部から離間し、且つ前記スカート部の連接部から離間した前記各辺におけるスカート部の外側面に、それぞれ外側方に突設された緩衝手段とを各々備えた上、下側トレイを具備し、前記上、下側トレイを前記ポケットが向合うように配置し、前記ポケット内に前記電子部品を収納するようにしたことを特徴としている。
【００１３】
更に、上記目的を達成するために、第５の発明に係わる電子部品用ソフトトレイでは、平面形状が四角形の平坦部と、前記平坦部の中央部に形成され、収納する電子部品の平面外形寸法より僅かに大きい寸法で、深さが前記電子部品の高さの１／２に設けられた凹部からなるポケットと、前記平坦部と反対側の前記平坦部の各辺から前記ポケットの突出方向に当該ポケットの深さを超えた位置まで延び、且つ互いに連接された平面形状が四角形のスカート部と、前記スカート部の外側面に、前記平坦部と反対側の下端から上方に向け、前記平坦部と前記スカート部との境界角部から離間して形成され、前記スカート部の連接部から離間し、且つ互いに離間配置された複数の台形状の緩衝タブと、前記緩衝タブ間を連結するように設けられた緩衝ツバとを各々備えた上、下側トレイを具備し、前記上、下側トレイの一方の平坦部に嵌合突起及び嵌合凹部の少なくとも一方を設け、他方の平坦部に前記嵌合突起及び嵌合凹部の少なくとも他方を設けてなり、前記上、下側トレイを前記ポケットが向合うように配置し、前記嵌合突起と前記嵌合凹部とを嵌合させることにより、前記上、下側トレイを一体化して前記ポケット内に前記電子部品を収納するようにしたことを特徴としている。
【００１４】
更に、上記目的を達成するために、第６の発明に係わる電子部品用ソフトトレイでは、平面形状が四角形の平坦部と、前記平坦部の中央部に形成され、収納する電子部品の平面外形寸法より僅かに大きい寸法で、深さが前記電子部品の高さの１／２に設けられた凹部からなるポケットと、前記平坦部の各辺から前記ポケットの突出方向に当該ポケットの深さを超えた位置まで延び、且つ互いに連接された平面形状が四角形のスカート部と、前記各辺におけるスカート部の前記平坦部と反対側の端部に設けられ、前記スカート部の連接部から離間し、且つ外側方に延長された緩衝ツバとを各々備えた上、下側トレイを具備し、
前記上、下側トレイの一方の平坦部に嵌合突起及び嵌合凹部の少なくとも一方を設け、他方の平坦部に前記嵌合突起及び嵌合凹部の少なくとも他方を設けてなり、前記上、下側トレイを前記ポケットが向合うように配置し、前記嵌合突起と前記嵌合凹部とを嵌合させることにより、前記上、下側トレイを一体化して前記ポケット内に前記電子部品を収納するようにしたことを特徴としている。
【００１５】
上記本発明の電子部品用ソフトトレイによれば、スカート部の外側面の一部に、平坦部とスカート部との境界角部より外側方に張出した緩衝手段を設けているので、特に、横方向からの外部衝撃に対して、緩衝手段によりスカート部が変形され、衝撃が吸収、或いは緩和されるため、電子部品の損傷が防止できる。
【００１６】
また、上記第５及び第６の発明の電子部品用ソフトトレイによれば、上、下側トレイの両者は、嵌合凹部及び嵌合凸部の嵌合により互いに一体化され、且つ固定されている。したがって、横方向からの外部衝撃が加わっても、一方のトレイが横方向にズレルことがなく、ズレによる衝撃が防止される。
【００１７】
【発明の実施の形態】
以下、本発明の実施の形態（以下、実施形態と称する）を図面を参照して説明する。
【００１８】
（第１の実施形態）
まず、本発明の第１の実施形態に係わる電子部品用ソフトトレイについて、図１乃至図６を参照して説明する。
【００１９】
図1乃至図４に示すように、電子部品用ソフトトレイ１は、下側トレイ２と上側トレイ３とから構成され、このトレイ２、３は、いずれも、例えばポリエチレンテレフタレートフィルム（一般に、ＰＥＴフィルムと称される）を真空成形することにより形成されている。
【００２０】
この上下側トレイ２、３は、いずれも、平面形状が四角形の平坦部４を有し、この平坦部４の中央部には、電子部品２０を収納するための凹部からなるポケット５が形成されている。このポケット５の凹部は、電子部品２０の平面外形寸法より僅かに大きい寸法に形成され、深さを電子部品の高さの１／２に形成している。
【００２１】
また、前記平坦部４の４隅には、嵌合凹部６または嵌合凸部７が形成されている。ここでは、一方の対向する隅には、嵌合凹部６を、また他方の対向する隅には、嵌合凸部７をそれぞれ形成している。
【００２２】
前記平坦部４の各辺には、前記ポケット５の凹部の突出方向と同じ方向に、各辺端部から延長された緩衝用のスカート部８ａ、８ｂ、８ｃ、８ｄがそれぞれ形成されている。各スカート部８ａ、８ｂ、８ｃ、８ｄは、前記ポケット５と略垂直で、且つ前記ポケット５の凹部深さ以上の長さに形成され、隣接する辺における前記スカート部は、互いに連接されている。
【００２３】
この各辺におけるスカート部８ａ、８ｂ、８ｃ、８ｄの外側面には、各々、緩衝部材としての複数、例えば２個の緩衝タブ９ａ、９ｂ、９ｃ、９ｄが互いに離間形成されている。各緩衝タブ９ａ、９ｂ、９ｃ、９ｄは、前記スカート部８ａ、８ｂ、８ｃ、８ｄの一部を外側方に張出すように成形してなる。また、各緩衝タブ９ａ、９ｂ、９ｃ、９ｄは、前記各スカート部８ａ、８ｂ、８ｃ、８ｄの下端部から上方の前記平坦部４方向に延びる縦長の台形状に形成されている。
【００２４】
更に、各スカート部８ａ、８ｂ、８ｃ、８ｄにおける前記緩衝タブ９ａ、９ａ間、９ｂ、９ｂ間、９ｃ、９ｃ間、９ｄ、９ｄ間には、緩衝部材としての緩衝ツバ１０ａ、１０ｂ、１０ｃ、１０ｄが、各々、前記緩衝タブ間を連結するように設けられている。
【００２５】
このような、電子部品用ソフトトレイを用いて電子部品を輸送、或いは搬送する場合について、図５を参照して説明する。
【００２６】
まず、前記下側トレイ２のポケット５に電子部品２０の下半分を収納する。
【００２７】
次に、前記上側トレイ３を、ポケット５が下向きになるように上下反転させて前記下側トレイ２上に配置して前記下側トレイ２上に被せることにより、前記電子部品２０の上半分を前記上側トレイ３のポケット５に収納させると共に、前記下側トレイ２の嵌合凹部６及び嵌合凸部７と前記上側トレイ３の嵌合凸部７及び嵌合凹部６とを、各々、嵌合させることにより、上下側トレイ２，３を互いに一体化させる。
【００２８】
そして、この電子部品用ソフトトレイ１を包装ケース（カートン）１２内に詰め込み、輸送、或いは搬送する。
【００２９】
次に、輸送、或いは搬送時に、外部から衝撃が加わった場合について、図６を参照して説明する。
【００３０】
もし、カートンを誤って落下させ、上下方向の衝撃が加わった場合には、従来と同様に、その衝撃が吸収、或いは緩和されることは説明するまでもない。
【００３１】
仮に、横方向（紙面で左右、前後）から衝撃が加わった場合には、図６に示すように、衝撃が加わった方向に存在する緩衝手段としての緩衝タブ９ａ、９ｂ、９ｃ、９ｄ及び緩衝ツバ１０ａ、１０ｂ、１０ｃ、１０ｄが、図中の破線から実線で示すように、スカート部８ａ、８ｂ、８ｃ、８ｄの側面を変形させて、衝撃を吸収、或いは緩和する。
【００３２】
上記実施形態によれば、各辺のスカート部８に外側方向に張出した緩衝手段としての緩衝タブ９及び緩衝ツバ１０を設けているので、横方向からの衝撃が加わった場合、構造上強度の大きい平坦部とスカート部との境界角部Ａに衝撃が加わる前に、前記緩衝タブ９及び前記緩衝ツバ１０に加わり、これにより前記スカート部８が変形されて、衝撃が吸収、或いは緩和される。したがって、電子部品には、衝撃が加わらず、電子部品の損傷を防止することができる。
【００３３】
また、従来の電子部品用ソフトトレイでは、下側トレイ上に上側トレイを被せているだけで、互いに固定されていないため、横方向からの衝撃が与えられると、上、下側トレイの一方が横方向にズレ、電子部品に衝撃を与える恐れがあるが、この実施形態の電子部品用ソフトトレイでは、上、下側トレイ２、３の両者は、嵌合凹部６及び嵌合凸部７の嵌合により互いに一体化され、且つ固定されている。したがって、従来のような、一方のトレイの横方向ズレによる衝撃が防止される。
【００３４】
（第２の実施形態）
次に、本発明の第２の実施形態に係わる電子部品用ソフトトレイについて、図７乃至図９を参照して説明する。なお、第１の実施形態と同一構成部分に同一符号を付して、詳しい説明は省略し、以下、相違する部分のみ説明する。
【００３５】
本実施形態が上記第１の実施形態と異なる点は、上記第１の実施形態における緩衝タブと緩衝ツバの組合からなる緩衝手段に代え、緩衝ツバのみで緩衝手段を構成したことにある。
【００３６】
即ち、本実施形態の電子部品用ソフトトレイでは、上、下側トレイは、図７に示すように、構成されている。図７では、説明を簡単にするため、下側トレイ２のみ示している。図７に示すように、トレイ２（３）では、四角形の平坦部４の各辺から延長された緩衝用のスカート部８ａ、８ｂ、８ｃ、８ｄには、緩衝ツバ３０ａ、３０ｂ、３０ｃ、３０ｄが、各々、形成されている。各緩衝ツバ３０ａ、３０ｂ、３０ｃ、３０ｄは、各スカート部８ａ、８ｂ、８ｃ、８ｄの下端部から外側方向に張出すように形成されている。
【００３７】
そして、このような、電子部品用ソフトトレイを用いた電子部品の輸送、或いは搬送は、上記第１の実施形態と同様にして行われる。
【００３８】
即ち、図８に示すように、まず、前記下側トレイ２のポケット５に電子部品２０の下半分を収納する。次に、前記上側トレイ３を、ポケット５が下向きになるように上下反転させて前記下側トレイ２上に配置して前記下側トレイ２上に被せることにより、前記電子部品２０の上半分を前記上側トレイ３のポケット５に収納させると共に、前記下側トレイ２の嵌合凹部６及び嵌合凸部７と前記上側トレイ３の嵌合凸部７及び嵌合凹部６とを、各々、嵌合させることにより、上下側トレイ２，３を互いに一体化させる。
【００３９】
そして、この電子部品用ソフトトレイ１を包装ケース（カートン）１２内に詰め込み、輸送、或いは搬送する。
【００４０】
もし仮に、電子部品の輸送、或いは搬送時に、カートンを誤って落下させ、上下方向の衝撃が加わった場合には、従来と同様に、その衝撃が吸収、或いは緩和されることは説明するまでもない。
【００４１】
仮に、横方向（紙面で左右、前後）から衝撃が加わった場合には、図９に示すように、衝撃が加わった方向に存在する緩衝手段としての緩衝ツバ３０ａ、３０ｂ、３０ｃ、３０ｄが、図中の破線から実線で示すように、スカート部８ａ、８ｂ、８ｃ、８ｄの側面を変形させて、衝撃を吸収、或いは緩和する。
【００４２】
上記実施形態によれば、各辺のスカート部８に外側方向に張出した緩衝手段としての緩衝ツバ３０を設けているので、横方向からの衝撃が加わった場合、構造上強度の大きい平坦部とスカート部との境界角部Ａに衝撃が加わる前に、前記緩衝ツバ３０に加わり、これにより前記スカート部８が変形されて、衝撃が吸収、或いは緩和される。したがって、電子部品には、衝撃が加わらず、電子部品の損傷を防止することができる。
【００４３】
また、上記実施形態と同様に、上、下側トレイ２、３は、嵌合凹部６及び嵌合凸部７の嵌合により互いに一体化され、且つ固定されているので、従来のような、一方のトレイの横方向ズレによる衝撃が防止される。
【００４４】
本発明は、上記実施形態に限定されるものではなく、特許請求の範囲を逸脱しない範囲で、種々、変形できることは勿論である。
【００４５】
上記実施形態では、嵌合凹部６及び嵌合凸部７の両方を、上下側トレイ２、３の平坦部４にそれぞれ形成しているが、一方のトレイには嵌合凹部のみを、他方のトレイには嵌合凸部のみを形成しても良い。
【００４６】
また、図１０に示すように、一方のトレイ、例えば下側トレイ２の平坦部４に、ポケット５を取囲むように環状の嵌合凸部４０を形成し、他方のトレイ、例えば上側トレイ３の平坦部４にポケット５を取囲むように環状の嵌合凹部５０を形成しても良い。
【００４７】
この構成によれば、嵌合凹凸部の形成が簡単で、しかもその嵌合による上下側トレイの一体化が容易に行えると共に、横方向からの衝撃に対して環状の嵌合凹凸部が衝撃を吸収、或いは緩和する機能を有し都合が良い。
【００４８】
更に、上記第１の実施形態では、緩衝手段として緩衝タブ９ａ、…９ｄと緩衝ツバ１０ａ、…１０ｄで構成したが、必ずしも両方を備える必要はなく、図１１に示すように、緩衝タブ６０ａ、６０ｂ、６０ｃ、６０ｄのみでも良い。
【００４９】
また更に、上記実施形態では、電子部品用ソフトトレイ１を上下側トレイ２，３から構成したが、上側トレイ３は必ずしも必要ではない。即ち、この場合には、図１２に示すように、下側トレイ２のポケット５を構成する凹部を、電子部品を完全に収納できる深さに形成しておき、輸送、或いは搬送する際には、電子部品がポケットから飛出さないように、粘着剤等の手段で固定して包装ケースに詰込めば良い。
【００５０】
この構成によっても、上記実施形態と同様に、横方向からの衝撃による電子部品の損傷が防止できる。
【００５１】
また更に、図１２に示す構成の電子部品用ソフトトレイの場合、積重ねて包装ケースに詰込むようにしても良い。
【００５２】
【発明の効果】
本発明の電子部品用ソフトトレイによれば、スカート部の外側面の一部に、平坦部とスカート部との境界角部より外側方に張出した緩衝手段を設けているので、特に、横方向からの外部緩衝に対して、緩衝手段によりスカート部が変形され、衝撃が吸収、或いは緩和されるため、電子部品の損傷が防止できる。

[0002]
[Prior art]
In recent years, with the reduction in size and thickness of electronic devices and the like, electronic components used in the flat pack type surface mount components such as QFP (Quad Flat-Leaded Package), SOP (Small Outline Package), etc. A large number of leads protruding in the lateral direction are fine and arranged at fine intervals. Therefore, when transporting or transporting such a surface mount component, it is necessary to pay attention not only to damage to the leads but also to deformation and breakage of the leads.

The trays 102 and 103 are formed with pockets 105 each having a concave portion that accommodates half of the thickness of the surface-mounted component 200 at the center of the flat portion 104 having a rectangular planar shape. Buffer skirts 108a, 108b, 108c, and 108d are formed in the same direction as the protruding direction of the recesses in the pocket 105. Each of the skirt portions 108 a, 108 b, 108 c, and 108 d is formed to be substantially perpendicular to the flat portion 104 and have a length greater than the depth of the concave portion in the pocket 105.
[0006]
Then, the lower half of the electronic component 200 is accommodated in the pocket 105 of the lower tray 102, and the upper tray 103 is turned over so that the pocket 105 faces downward, and is placed on the lower tray 102, and the upper tray The upper half of the electronic component 200 is accommodated in the pocket 105 of 103, the upper and lower trays 102 and 103 are integrated, and the electronic component soft tray 101 is packed in a packaging case (carton) 120 as shown in FIG. They are packed and transported or transported.

[Problems to be solved by the invention]
However, such electronic component soft trays have the following problems. That is, during transportation or transportation, for example, when the product falls and receives an impact from the vertical direction (up and down on the paper surface), the buffer is absorbed or relaxed by the deformation of the periphery of the flat part and the skirt part. The However, when an impact is applied from the lateral direction (front and rear, left and right on the paper surface), as shown in FIG. 17, the boundary corner portion A where the flat portion 104 and the skirt portion 105 are connected is structurally strong and deformed. Since it is difficult, the impact is not absorbed or alleviated, and the surface mount product main body and the lead are damaged, deformed, or broken by the impact.
