Description

【０００１】
【発明の属する技術分野】
本発明は、半導体素子の電極と外部リードとの結線に用いるボンディングワイヤを収納保持するためのスプールケースに関する。
【０００２】
【従来の技術】
従来から、ボンディングワイヤは円筒状のスプールに多層に巻かれ、スプールケース内に収納した状態で、移送及び保管されている。一方、ワイヤボンディング時には、スプールケースから人手によりボンディングワイヤをスプールごと取り出している。
【０００３】
かかるスプールケースは、例えば実開昭５４−１０３７４７号公報に開示され且つ図５に示すように、プラスチックを成形して形成した容器本体１と蓋体２とからなっている。この容器本体１の突出外縁部３に蓋体２の周壁部５を嵌合することにより、その内部にスプールに巻回したボンディングワイヤ（図示せず）をほぼ気密状態に収納保持するようになっている。
【０００４】
具体的には、容器本体１は図６に示すように、１枚のプラスチックシートを成形したものであり、略正方形の底板部４と、その上に隆起して形成された突出外縁部３とを備えると共に、底板部４のほぼ中央部にスプールの一端開口部を嵌合保持するスプール保持部６ａが隆起して形成してある。
【０００５】
尚、蓋体２の天井部内側には底板部４のスプール保持部６ａよりも小径のスプール保持部６ｂが設けてあり、突出外縁部３に嵌合保持されたスプールの他端開口部を挿入してスプールが外れたり又はがたついたりしないよう、また蓋体２を開けたときスプールが底板部４のスプール保持部６ａに保持されるようになっている。また、突出外縁部３は一部が円弧状をなし、その近傍で外側に突き出た底板部４の部分は指先で保持するための保持片４ａ、４ａとなっている。
【０００６】
【発明が解決しようとする課題】
上記スプールケースを開封してスプールを取り出す際には、片方の手で容器本体１の保持片４ａ、４ａを抱え込む様に保持しながら、もう一方の手で蓋体２を掴んで両者を引き離していた。しかし、容器本体１と蓋体２はほぼ気密状態に嵌合固定されているため引き離しが容易ではなく、強い力を必要とするうえ、蓋体２を開けた時の反動でスプールが飛び出し、それに巻かれているボンディングワイヤが損傷する事態も稀ではあるが起きていた。
【０００７】
特に、ケース本体や蓋体がプラスチック製であるため、成形時の仕上がり寸法にバラツキがあるうえ、繰返し使用による磨耗、変質、変形、劣化などにより容器本体と蓋体の組合せに寸法が変わりやすい。そのため容器本体と蓋体の嵌合力ないし係止力が一定せず、蓋体の取り外し時の反動が大きくなり、スプールが飛び出して脱落することがあった。
【０００８】
また、図７に示すように、容器本体１は両端部の保持片４ａ、４ａを中心に把持されるのに対して、蓋体２は通常その中央部を掴むことになるので、蓋体２は容器本体１に対して垂直上方に引き上げられるのではなく、ある角度をもって斜めに引き上げられることが多かった。このように蓋体２が容器本体１に対して斜めに引き離されると、蓋体２の下端縁が容器本体１に保持されているスプール１０に巻き付けたボンディングワイヤ（図示せず）に接触し、その表面を傷つけやすいという問題があった。
【０００９】
尚、スプールケースは比較的変形しやすいプラスチックであるため、嵌合状態で突出外縁部３よりも若干上方の蓋体２の周壁部５を指で押して変形させ、滑らせるように蓋体２を引き離すことも行われてきた。しかしながら、この方法は、蓋体２を強く押しすぎると内部に収納されているボンディングワイヤを誤って損傷させる危険があるため望ましい方法とは言い難い。
【００１０】
更には、上記した蓋体２を斜め方向に引き離す操作や、蓋体２の周壁部５を押して引き離す操作は、突出外縁部３や周壁部５に無理な力が働くため、容器本体１や蓋体２の寿命を縮めやすく、繰返し使用できる期間が短くなるなどの問題もあった。
【００１１】
本発明は、このような従来の事情に鑑み、開封して容器本体から蓋体を取り外す際に、強い力を必要とせず、且つ蓋体をほぼ垂直上方に容易に引き離すことができ、スプールに保持されたボンディングワイヤを損傷することなく安全に取り出すことができるスプールケースを提供することを目的とする。
【００１２】
【課題を解決するための手段】
上記目的を達成するため、本発明が提供するボンディングワイヤ用スプールケースは、プラスチック製の容器本体と蓋体からなり、ボンディングワイヤが巻回された円筒状のスプールを収納保持するスプールケースであって、前記容器本体はスプールの少なくとも一端開口部を嵌合保持するスプール保持部と、スプール保持部の外側に設けた突出外縁部とを備え、前記蓋体は前記容器本体の突出外縁部に着脱自在に嵌合する周壁部を備えると共に、該周壁部の下端縁に前記容器本体の突出外縁部の高さより低い少なくとも二つの開封時指当て用の切欠部を有し、前記容器本体の突出外縁部における蓋体の周壁部の切欠部に対応する部分が他の部分よりも外側に突出した把持部となっていることを特徴とするものである。
【００１３】
上記本発明のボンディングワイヤ用スプールケースにおいては、前記容器本体の突出外縁部における蓋体の周壁部の切欠部に対応する部分が、他の部分と識別可能に着色されていることを特徴とする。
【００１４】
また、上記本発明のボンディングワイヤ用スプールケースにおいては、前記蓋体の周壁部に設けた切欠部は、横幅が２０ｍｍ以上であって、高さが２０ｍｍ以上で且つ前記容器本体の突出外縁部の高さを越えないことを特徴とする。
【００１５】
【発明の実施の形態】
本発明のスプールケースは、プラスチック製の容器本体と蓋体からなり、その基本的な構造は従来と同様である。即ち、例えば図１及び図２に示す容器本体１１と蓋体１２はプラスチックシートを加熱圧縮成形して形成したものであり、容器本体１１にはスプールの少なくとも一端開口部を嵌合保持するスプール保持部１６ａと、このスプール保持部１６ａの外側に突出外縁部１３とが、それぞれ底板部１４から隆起して形成されている。一方、蓋体１２は周壁部１５を備え、容器本体１１の突出外縁部１３に着脱自在に嵌合するようになっている。
【００１６】
尚、図示した具体例では、スプールの他端開口部を挿入するため底板部１４のスプール保持部１６ａよりも小径のスプール保持部１６ｂを蓋体１２の天井部に設けているが、蓋体１２の天井部がスプールの他端に接するか又は極めて近接した状態、即ち周壁部１５の高さをスプールの高さとほぼ同一に設定すれば、蓋体１２にスプール保持部１６ｂを設けなくても、スプールのがたつきやスプール保持部１６ｂからの外れを防ぐことができる。また、容器本体と蓋体は、加熱圧縮成形以外の方法、例えば射出成形等によって形成することもできる。
【００１７】
本発明のスプールケースでは、この蓋体１２の周壁部１５の下端縁に、開封時指当て用の切欠部１７が少なくとも二つ設けてある。これらの切欠部１７の高さ（切り込み深さ）は、ケース内の気密状態を保持するために、容器本体１１の突出外縁部１３の高さよりも低くなっている。また、周壁部１５に設ける切欠部１７の数は、開封時に指を当てて把持するように二つ以上とする。切欠部１７を向ける位置は、指を当てて把持しやければ良く、例えば二つの切欠部１７の場合には親指と中指を当てやすいように互いにほぼ対向する位置に配置することが好ましい。
【００１８】
この蓋体１２の周壁部１５を容器本体１１の突出外縁部１３に嵌合させると、図２に示すように、容器本体１１の突出外縁部１３の一部が蓋体１２に覆われることなく、蓋体１２の切欠部１７から露出する。従って、図３に示すように、開封時には、蓋体１２の切欠部１７から露出した突出外縁部１３に片方の手の指を当てて把持しながら、他方の手で蓋体１２を掴んで互いに引き離せば、ほぼ垂直方向に蓋体１２を容易に引き離してケースを開封することができる。
【００１９】
また、蓋体１２を容器本体１１に嵌合したケースはほぼ気密状態を維持しているが、切欠部１７から露出した突出外縁部１３を指で内側に押すことにより気密状態が開放され、より一層簡単に蓋体１２を引き離すことができる。しかも、突出外縁部１３は１枚のプラスチックシートを成形した２重構造であり、比較的厚みがあるため、内側に押して歪めてもボンディングワイヤに接触して損傷を与える危険がない。尚、突出外縁部１３の上端側に切欠溝を設ければ蓋体１２の引き離しが一層容易になるが、切欠溝によってケース自体の気密状態が損なわれないように、その形状や位置などに注意して成形する必要がある。
【００２０】
蓋体１２の周壁部１５に設ける切欠部１７の大きさは、少なくとも指先で切欠部１７から露出した突出外縁部１３を掴むことができる程度の大きさを必要とする。具体的は図１（ａ）に示すように、切欠部１７の横幅ｗは２０ｍｍ以上あることが好まく、また切欠部１７の高さｈは２０ｍｍ以上が好ましい。また、切欠部１７を二つ設けた場合の位置は、蓋体１２の中心軸を挟んで互いに対向する位置にあることが、蓋体１２を引き離す際に斜めにならず、垂直方向に引き上げやすいため望ましい。
【００２１】
ただし、切欠部１７の高さｈが容器本体１１の突出外縁部１３の高さよりも高くなると、スプールケース内の気密状態が保てなくなり、内部に収納されたボンディングワイヤにゴミ等が付着することになる。従って、必要な切欠部１７の高さに応じて突出外縁部１３の高さを高くして、確実にスプールケース内部の気密状態を保つようにしなければならない。尚、切欠部１７の形状は、切欠部１７から露出した部分の突出外縁部１３を指先で掴めればよく、半円形、半楕円形、多角形等であってよい。
【００２２】
また、蓋体は内部に収納されたボンディングワイヤが見えるように、透明のプラスチックで形成されている。従って、蓋体の周壁部に切欠部を形成しても、その部分が見え難いことがある。そこで、図４に示すように、容器本体１１の突出外縁部１３のうち、容器本体１１と蓋体１２を嵌合したとき、蓋体１２の切欠部１７に対応する部分（切欠部１７から露出する部分）のみを、他の部分よりも外側に突出させて把持部１８を形成するか、又は容易に認識できる色彩に着色するか、若しくは両者を組み合わせることにより、切欠部１７を容易に識別することができ便利である。
【００２３】
【発明の効果】
本発明によれば、容器本体から蓋体を取り外す際に強い力を必要とせず、しかも蓋体をほぼ垂直上方に容易に引き離すことが可能なボンディングワイヤ用スプールケースを提供することができる。従って、スプールに保持されてスプールケース内に収納されたボンディングワイヤを、蓋体を取り外す際に傷つけることなく安全に取り出すことができる。

BACKGROUND OF THE INVENTION
The present invention relates to a spool case for storing and holding a bonding wire used for connecting an electrode of a semiconductor element and an external lead.
[0002]
[Prior art]
Conventionally, bonding wires are wound and wound around a cylindrical spool in multiple layers, and are transferred and stored in a state of being housed in a spool case. On the other hand, at the time of wire bonding, the bonding wire is taken out from the spool case by hand.
[0003]
Such a spool case includes, for example, a container body 1 and a lid 2 formed by molding plastic as disclosed in Japanese Utility Model Laid-Open No. 54-103747 and as shown in FIG. By fitting the peripheral wall portion 5 of the lid 2 to the protruding outer edge portion 3 of the container body 1, a bonding wire (not shown) wound around the spool is accommodated and held in an almost airtight state. ing.
[0004]
Specifically, as shown in FIG. 6, the container body 1 is formed by molding a single plastic sheet, and includes a substantially square bottom plate portion 4 and a protruding outer edge portion 3 formed so as to protrude thereon. And a spool holding portion 6a for fitting and holding the one end opening of the spool is formed at the substantially central portion of the bottom plate portion 4 so as to be raised.
[0005]
In addition, a spool holding portion 6b having a smaller diameter than the spool holding portion 6a of the bottom plate portion 4 is provided inside the ceiling portion of the lid body 2, and the other end opening portion of the spool fitted and held in the protruding outer edge portion 3 is inserted. Thus, the spool is held by the spool holding portion 6a of the bottom plate portion 4 when the lid 2 is opened so that the spool does not come off or rattle. Further, a part of the protruding outer edge portion 3 has an arc shape, and the portion of the bottom plate portion 4 protruding outward in the vicinity thereof is holding pieces 4a and 4a for holding by the fingertips.
[0006]
[Problems to be solved by the invention]
When the spool case is opened and the spool is taken out, while holding the holding pieces 4a and 4a of the container body 1 with one hand, the other hand holds the lid 2 and pulls them apart. It was. However, since the container body 1 and the lid body 2 are fitted and fixed in an almost airtight state, it is not easy to separate, and requires a strong force, and the spool pops out by the reaction when the lid body 2 is opened. Although rarely, the wound bonding wire was damaged.
[0007]
In particular, since the case main body and the lid are made of plastic, the finished dimensions at the time of molding vary, and the dimensions are likely to change depending on the combination of the container main body and the lid due to wear, alteration, deformation, deterioration due to repeated use. Therefore, the fitting force or locking force between the container main body and the lid body is not constant, and the reaction at the time of removing the lid body becomes large, and the spool may jump out and fall off.
[0008]
Further, as shown in FIG. 7, the container body 1 is gripped around the holding pieces 4 a and 4 a at both ends, whereas the lid body 2 normally grips the central portion thereof, so that the lid body 2 In many cases, the container is not pulled vertically upward with respect to the container body 1 but is tilted at an angle. When the lid body 2 is pulled obliquely away from the container body 1 in this way, the lower end edge of the lid body 2 comes into contact with a bonding wire (not shown) wound around the spool 10 held by the container body 1, There was a problem that the surface was easily damaged.
[0009]
Since the spool case is made of a plastic that is relatively easily deformed, the peripheral wall portion 5 of the lid body 2 slightly above the protruding outer edge portion 3 in the fitted state is pushed and deformed by a finger so that the lid body 2 can be slid. They have also been pulled apart. However, this method is not a desirable method because there is a risk of accidentally damaging the bonding wire housed inside if the lid 2 is pressed too hard.
[0010]
Furthermore, the operation of pulling away the lid 2 in the oblique direction and the operation of pushing and pulling away the peripheral wall 5 of the lid 2 exert an unreasonable force on the projecting outer edge 3 and the peripheral wall 5. There were also problems such as easy shortening of the life of the body 2 and shortening the period of repeated use.
[0011]
In view of such a conventional situation, the present invention does not require a strong force when opening and removing the lid from the container body, and the lid can be easily pulled up substantially vertically upward. It is an object of the present invention to provide a spool case that can be safely taken out without damaging the held bonding wire.
[0012]
[Means for Solving the Problems]
To achieve the above object, the present invention provides a bonding wire spool case comprising a plastic container main body and a lid, and storing and holding a cylindrical spool around which a bonding wire is wound. The container main body includes a spool holding portion that fits and holds at least one end opening of the spool, and a protruding outer edge portion provided outside the spool holding portion, and the lid body is detachable from the protruding outer edge portion of the container main body. And has at least two notch portions for finger contact at the time of opening lower than the height of the protruding outer edge portion of the container body at the lower end edge of the peripheral wall portion, and the protruding outer edge portion of the container body The part corresponding to the notch part of the peripheral wall part of the lid body is a grip part protruding outward from the other part .
[0013]
In the bonding wire spool case of the present invention, a portion corresponding to the cutout portion of the peripheral wall portion of the lid body in the protruding outer edge portion of the container body is colored so as to be distinguishable from other portions. .
[0014]
In the bonding wire spool case of the present invention, the cutout portion provided in the peripheral wall portion of the lid body has a width of 20 mm or more, a height of 20 mm or more, and a protruding outer edge portion of the container body. It is characterized by not exceeding the height.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
The spool case of the present invention comprises a plastic container body and a lid, and the basic structure thereof is the same as in the prior art. That is, for example, the container body 11 and the lid body 12 shown in FIGS. 1 and 2 are formed by heat compression molding a plastic sheet, and the container body 11 has a spool holding for fitting and holding at least one end opening of the spool. A part 16a and a protruding outer edge part 13 are formed on the outside of the spool holding part 16a so as to protrude from the bottom plate part 14, respectively. On the other hand, the lid body 12 includes a peripheral wall portion 15 and is detachably fitted to the protruding outer edge portion 13 of the container body 11.
[0016]
In the illustrated example, a spool holding portion 16b having a diameter smaller than that of the spool holding portion 16a of the bottom plate portion 14 is provided on the ceiling portion of the lid body 12 in order to insert the other end opening of the spool. If the ceiling portion of the cover is in contact with or very close to the other end of the spool, that is, if the height of the peripheral wall portion 15 is set to be substantially the same as the height of the spool, the spool 12 does not have to be provided with the spool holding portion 16b. It is possible to prevent the spool from rattling or coming off from the spool holding portion 16b. The container body and the lid can be formed by a method other than heat compression molding, for example, injection molding.
[0017]
In the spool case of the present invention, at least two notch portions 17 for finger contact at the time of opening are provided at the lower end edge of the peripheral wall portion 15 of the lid body 12. The height (cut depth) of these notches 17 is lower than the height of the protruding outer edge 13 of the container body 11 in order to maintain an airtight state in the case. Moreover, the number of the notch parts 17 provided in the surrounding wall part 15 shall be two or more so that a finger may be held and grasped at the time of opening. The position to which the cutout portion 17 is directed may be as long as it is easy to touch with a finger. For example, in the case of the two cutout portions 17, it is preferable that the cutout portion 17 is disposed at a position substantially opposite to each other so that the thumb and the middle finger can be easily applied.
[0018]
When the peripheral wall portion 15 of the lid body 12 is fitted to the protruding outer edge portion 13 of the container body 11, a part of the protruding outer edge portion 13 of the container body 11 is not covered with the lid body 12 as shown in FIG. 2. , Exposed from the notch 17 of the lid 12. Therefore, as shown in FIG. 3, at the time of opening, while holding the lid 12 with the finger of one hand against the protruding outer edge 13 exposed from the notch 17 of the lid 12, the other hand holds the lid 12 and holds each other. If pulled apart, the case 12 can be opened by easily separating the lid 12 in the substantially vertical direction.
[0019]
In addition, the case where the lid 12 is fitted to the container main body 11 is maintained in an almost airtight state, but the airtight state is released by pushing the protruding outer edge portion 13 exposed from the notch portion 17 inward with a finger. The lid 12 can be pulled away more easily. Moreover, the protruding outer edge portion 13 has a double structure formed by molding one plastic sheet and has a relatively large thickness. Therefore, there is no danger of contact with the bonding wire and damage even if it is distorted by being pushed inward. In addition, if the notch groove is provided on the upper end side of the protruding outer edge portion 13, the lid body 12 can be separated more easily, but attention should be paid to its shape and position so that the airtight state of the case itself is not impaired by the notch groove. And need to be molded.
[0020]
The size of the notch 17 provided in the peripheral wall portion 15 of the lid 12 needs to be large enough to at least hold the protruding outer edge 13 exposed from the notch 17 with the fingertip. Specifically, as shown in FIG. 1A, the lateral width w of the notch 17 is preferably 20 mm or more, and the height h of the notch 17 is preferably 20 mm or more. Further, when the two notches 17 are provided, the positions where the notches 17 face each other across the central axis of the lid 12 are not inclined when the lid 12 is pulled apart, and are easily pulled up in the vertical direction. Therefore it is desirable.
[0021]
However, if the height h of the notch portion 17 is higher than the height of the protruding outer edge portion 13 of the container body 11, the airtight state in the spool case cannot be maintained, and dust or the like adheres to the bonding wire housed inside. become. Therefore, it is necessary to increase the height of the protruding outer edge portion 13 in accordance with the required height of the notch portion 17 so as to reliably maintain the airtight state inside the spool case. In addition, the shape of the notch part 17 should just hold the protrusion outer edge part 13 of the part exposed from the notch part 17 with a fingertip, and may be a semicircle, a semi-elliptical shape, a polygon.
[0022]
Further, the lid is formed of a transparent plastic so that the bonding wire housed inside can be seen. Therefore, even if a notch is formed in the peripheral wall portion of the lid, the portion may be difficult to see. Therefore, as shown in FIG. 4, when the container body 11 and the lid body 12 are fitted to each other, the portion corresponding to the notch portion 17 of the lid body 12 (exposed from the notch portion 17). The notch portion 17 is easily identified by forming the gripping portion 18 by projecting only the portion) to the outside of the other portion, or by coloring the portion in a color that can be easily recognized, or by combining both. Can be convenient.
