Abstract
Description
【0001】
【発明の属する技術分野】
本発明は、実装位置がずれることのない基板に電子部品を接続する方法に関する。
【0002】
【従来の技術】
電極パターンが形成されている基板と電子部品との接続は、通常ハンダペーストや導電性微粒子等の導電接続材料を用いて行われる。この際、基板と電子部品との実装位置がずれてしまうことがあり、場合によっては接続信頼性が保てないこともある。比較的小さな電子部品ではハンダリフローにおいて溶融するハンダペースト等の導電接続材料の働きによって実装位置のずれを防ぐこともできるが(セルフアライメント効果)、特に表面積の大きな電子部品、例えば、表面実装型のコネクタや、タッチパネルや液晶パネルに用いられるガラス基板等とフレキシブル配線基板とを接続する場合では、このようなセルフアライメント効果も期待できない。そこで、なんらかの方法により接続前の基板と電子部品とを固定する必要があった。
【0003】
従来、このような部品を固定する方法としては、ハンダ耐熱性を有する耐熱接着シートで固定する方法が一般的であった。しかしながら、耐熱接着シートで固定した場合、接続完了後には耐熱接着シートを引き剥がす必要があるため、糊残りが生じて外観を損ねたり、剥離の際に接続されていた電子部品の接続を破壊してしまったりするという問題があった。特に、リードフレームを有する半導体パッケージでは、リード先端にダウンセット加工が施されてあっても基板の電極面から離れるおそれがあるので、接着剤や接着テープでリード先端が電極面から離れないように固定していたが、リードを接続した後もリードに樹脂が付着した状態となるため、樹脂の劣化がリードに影響を与えるおそれがあった。
【0004】
【発明が解決しようとする課題】
本発明は、上記現状に鑑み、実装位置がずれることのない基板に電子部品を接続する方法を提供することを目的とする。
【0005】
【課題を解決するための手段】
本発明1は、基板の電極と電子部品の電極とを導電接続材料を介して対向させて配置し、前記基板上に配置した電子部品を加熱消滅性接着シートで押さえて固定した後、前記導電接続材料を電極に融着させて前記基板と前記電子部品とを導電接続し、また、前記加熱消滅性接着シートを加熱して消滅させて基板に電子部品を接続する方法である。
【0006】
本発明2は、基板の電極と前記電子部品の電極とを導電接続材料を介して対向させ、シート状又はペースト状の加熱消滅性接着剤により前記基板と前記電子部品とを接着した後、前記導電接続材料を電極に融着させて前記基板と前記電子部品とを導電接続し、また、前記加熱消滅性接着剤を加熱して消滅させて基板に電子部品を接続する方法である。
以下に本発明を詳述する。
【0007】
本発明は、電極が形成されている基板に電子部品を接続する方法である。
本発明の基板に電子部品を接続する方法によって接続される基板としては、電極が形成されているものであれば特に限定されず、例えば、フレキシブルプリント基板、リジット基板等が挙げられる。また、本発明の基板に電子部品を接続する方法によって接続される電子部品としては特に限定されず、例えば、半導体チップ、キャパシタ等が挙げられる。
【0008】
本発明1の基板に電子部品を接続する方法では、まず、上記基板の電極と上記電子部品の電極とを導電接続材料を介して対向させて配置する。
上記導電接続材料としては特に限定されず、例えば、ハンダ等の150〜260℃程度の比較的低温度で溶融し得る金属;ハンダ粒子やAuやNi等の貴金属粒子;表面にハンダや貴金属等の金属層を有する導電性微粒子;ACF、ACPなの異方導電材料等が挙げられる。
上記導電接続材料は、予め基板及び/又は電子部品の電極上に配置されていてもよい。予め基板及び/又は電子部品の電極上に導電接続材料を配置する方法としては特に限定されず、例えば、電極の位置に孔を開けたメッシュ等を通してスキージでハンダをスクリーン印刷する方法等が挙げられる。
【0009】
本発明1の基板に電子部品を接続する方法では、次いで、上記基板上に配置した電子部品を加熱消滅性接着シートで押さえて固定する。これにより、基板と電子部品とが仮固定され、接続が完了するまで実装位置がずれることがない。
上記固定する方法としては特に限定されず、例えば、電子部品全体を覆うようにしてシートを被せてもよいし、電子部品の四辺又は四隅をシートにより固定してもよい。また、リードフレームを有する半導体パッケージの固定においても、各辺のリードを上記加熱消滅性接着シートで押さえて固定すればよい。
【0010】
本明細書において加熱消滅性接着シートとは、少なくとも、加熱することにより気体に分解するか、分解して気化し、固体形状を失う加熱消滅性接着剤からなる接着層を有するシートを意味する。なお、上記加熱消滅性接着シートが基材の片面又は両面に加熱消滅性接着剤層が形成されたサポートタイプである場合には、基材を含めたシート全体が加熱により消滅することが好ましいが、基材は消滅しなくとも加熱消滅性接着剤層が消滅すればよい。
このような加熱消滅性接着剤としては、例えば、ポリメチレンマロン酸ジエステル、ポリブチレン、ニトロセルロース、α−メチルスチレンポリマー、プロピレンカーボネートポリマー、ポリ(メタ)アクリル酸アルキルエステル、ポリブテン、ポリメタクリル酸ラウリル、カルボン酸ジヒドラジドとジイソシアネートを重合させた共重合体、これらのポリマーの過酸化物等が挙げられる。更に、これらのポリマーに必要に応じてジブチルフタレートやジオクチルフタレート等の可塑剤や、キシレンオイル、テルペンオイル、パラフィンワックス等の軟化剤を加えて粘着性を付与してもよい。
【0011】
しかしながら、通常の基板に電子部品を接続する方法では、ハンダリフロー工程でハンダ等の導電接続材料を電極面に融着させて接続を行うことが一般的であることから、リフロー温度である150〜260℃で消滅し得る接着剤を用いれば、リフロー時に加熱消滅性接着剤を消滅させることができ、大幅に工程を簡略化できる。また、比較的耐熱性の低い電子部品にも用いることができる。従来、150〜260℃で速やかに消滅し得る接着剤はなかったが、本発明者らは、鋭意検討の結果、架橋性シリル基を有するポリオキシアルキレン樹脂組成物を架橋させた接着剤が、150〜260℃に加熱することで速やかに消滅することを見出した。更に、上記接着剤は、導電性微粒子等の金属や、シリコン材料、プラスチック材料等の幅広い材料に対して優れた接着性を有し、しかも、シート状に成形したときに適度なシート強度を有することを見出した。
【0012】
上記ポリオキシアルキレン樹脂としては特に限定されず、例えば、ポリオキシプロピレン樹脂、ポリオキシエチレン樹脂、ポリオキシテトラメチレン樹脂等が挙げられる。
また、これらのポリオキシアルキレン樹脂を複数種組み合わせることにより、加熱消滅性粘着シートが消滅する温度と消滅するまでの時間とを調整することができる。特に、ポリオキシプロピレン樹脂を50重量%以上とし、ポリオキシエチレン樹脂又はポリオキシテトラメチレン樹脂を含む混合樹脂として用いた場合、樹脂の混合割合を調整することにより、加熱消滅性粘着シートが消滅する温度と消滅するまでの時間とを容易に調整できる。例えば、ハンダリフローを複数回通過させるような工程に上記加熱消滅性接着シートを用いる場合には、リフローごとに電極面に融着した導電接続材料部分が再溶融するため、再溶融時に電子部品がずれるおそれがある。このため、例えば、ハンダリフロー時の温度では消滅せずに、それ以上の温度で消滅するように上記加熱消滅性接着シートを設計することにより、数回のハンダリフロー工程を通過させるまで電子部品を仮固定したい場合にも好適に用いることができる。
【0013】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for connecting an electronic component to a substrate on which a mounting position does not shift.
[0002]
[Prior art]
The connection between the substrate on which the electrode pattern is formed and the electronic component is usually performed using a conductive connection material such as a solder paste or conductive fine particles. At this time, the mounting position of the substrate and the electronic component may be shifted, and in some cases, connection reliability may not be maintained. For a relatively small electronic component, the displacement of the mounting position can be prevented by the function of a conductive connection material such as a solder paste that melts during solder reflow (self-alignment effect), but an electronic component having a particularly large surface area, for example, a surface mount type Such a self-alignment effect cannot be expected when a flexible wiring board is connected to a connector, a glass substrate used for a touch panel or a liquid crystal panel, or the like. Therefore, it is necessary to fix the board and the electronic component before connection by some method.
[0003]
Conventionally, as a method of fixing such components, a method of fixing with a heat-resistant adhesive sheet having solder heat resistance has been generally used. However, when fixing with a heat-resistant adhesive sheet, it is necessary to peel off the heat-resistant adhesive sheet after the connection is completed, so that glue residue may occur and damage the appearance, or break the connection of the electronic components connected at the time of peeling. There was a problem of getting lost. In particular, in a semiconductor package having a lead frame, even if the lead tip is downset, the lead tip may be separated from the electrode surface of the substrate. Although fixed, the resin remains attached to the leads even after the leads are connected, so that deterioration of the resin may affect the leads.
[0004]
[Problems to be solved by the invention]
The present invention has been made in view of the above circumstances, and has as its object to provide a method for connecting an electronic component to a substrate on which a mounting position does not shift.
[0005]
[Means for Solving the Problems]
The present invention 1 provides an arrangement in which electrodes of a substrate and electrodes of an electronic component are opposed to each other via a conductive connection material, and the electronic component arranged on the substrate is pressed and fixed with a heat-destructible adhesive sheet, and then the conductive material is fixed. A method of electrically connecting the substrate and the electronic component by fusing a connection material to an electrode, and connecting the electronic component to the substrate by heating and extinguishing the heat extinguishing adhesive sheet.
[0006]
The second aspect of the present invention provides a method in which the electrodes of the substrate and the electrodes of the electronic component are opposed to each other via a conductive connection material, and the substrate and the electronic component are bonded to each other with a sheet-like or paste-like heat-dissipating adhesive. A method of electrically connecting the substrate and the electronic component by fusing a conductive connecting material to an electrode, and connecting the electronic component to the substrate by heating and extinguishing the heat-destructible adhesive.
Hereinafter, the present invention will be described in detail.
[0007]
The present invention is a method for connecting an electronic component to a substrate on which electrodes are formed.
The substrate connected by the method for connecting electronic components to the substrate of the present invention is not particularly limited as long as it has electrodes formed thereon, and examples thereof include a flexible printed board and a rigid board. Further, the electronic component connected by the method for connecting an electronic component to the substrate of the present invention is not particularly limited, and examples thereof include a semiconductor chip and a capacitor.
[0008]
In the method of connecting an electronic component to a substrate according to the first aspect of the present invention, first, the electrodes of the substrate and the electrodes of the electronic component are arranged to face each other with a conductive connection material interposed therebetween.
The conductive connection material is not particularly limited. For example, a metal such as solder that can be melted at a relatively low temperature of about 150 to 260 ° C .; a solder particle or a noble metal particle such as Au or Ni; Conductive fine particles having a metal layer; an anisotropic conductive material such as ACF and ACP;
The conductive connection material may be previously arranged on a substrate and / or an electrode of an electronic component. The method for previously disposing the conductive connection material on the electrodes of the substrate and / or the electronic component is not particularly limited, and examples thereof include a method of screen-printing solder with a squeegee through a mesh or the like having holes at the positions of the electrodes. .
[0009]
In the method for connecting an electronic component to a substrate according to the first aspect of the present invention, the electronic component arranged on the substrate is then fixed by pressing with a heat-destructible adhesive sheet. Thereby, the board and the electronic component are temporarily fixed, and the mounting position does not shift until the connection is completed.
The fixing method is not particularly limited. For example, a sheet may be covered so as to cover the entire electronic component, or four sides or four corners of the electronic component may be fixed by the sheet. Also, in fixing a semiconductor package having a lead frame, the leads on each side may be pressed and fixed with the heat-dissipating adhesive sheet.
[0010]
As used herein, the term “heat-dissipating adhesive sheet” means a sheet having at least an adhesive layer made of a heat-dissipating adhesive that decomposes into a gas when heated or decomposes and vaporizes to lose a solid shape. In the case where the heat extinguishing adhesive sheet is a support type in which a heat extinguishing adhesive layer is formed on one or both sides of the base material, it is preferable that the entire sheet including the base material be extinguished by heating. It is sufficient that the heat extinguishing adhesive layer disappears even if the substrate does not disappear.
Examples of such a heat-destructible adhesive include polymethylene malonic acid diester, polybutylene, nitrocellulose, α-methylstyrene polymer, propylene carbonate polymer, poly (meth) acrylic acid alkyl ester, polybutene, poly (lauryl methacrylate), Copolymers obtained by polymerizing carboxylic acid dihydrazide and diisocyanate, peroxides of these polymers, and the like are included. Further, if necessary, a plasticizer such as dibutyl phthalate or dioctyl phthalate, or a softener such as xylene oil, terpene oil, or paraffin wax may be added to these polymers to impart tackiness.
[0011]
However, in a method of connecting an electronic component to an ordinary substrate, it is common to perform a connection by fusing a conductive connection material such as solder to an electrode surface in a solder reflow process. If an adhesive that can be eliminated at 260 ° C. is used, the heat-dissipable adhesive can be eliminated during reflow, and the process can be greatly simplified. Further, it can be used for electronic components having relatively low heat resistance. Conventionally, there was no adhesive that could quickly disappear at 150 to 260 ° C., but as a result of intensive studies, the present inventors found that an adhesive obtained by crosslinking a polyoxyalkylene resin composition having a crosslinkable silyl group, It has been found that it disappears quickly by heating to 150 to 260 ° C. Further, the adhesive has excellent adhesiveness to a wide range of materials such as metals such as conductive fine particles, silicon materials, and plastic materials, and has an appropriate sheet strength when formed into a sheet. I found that.
[0012]
The polyoxyalkylene resin is not particularly limited, and includes, for example, polyoxypropylene resin, polyoxyethylene resin, polyoxytetramethylene resin and the like.
In addition, by combining a plurality of these polyoxyalkylene resins, it is possible to adjust the temperature at which the heat-destructible pressure-sensitive adhesive sheet disappears and the time required for the sheet to disappear. In particular, when the polyoxypropylene resin is 50% by weight or more and used as a mixed resin containing a polyoxyethylene resin or a polyoxytetramethylene resin, the heat extinguishing pressure-sensitive adhesive sheet disappears by adjusting the mixing ratio of the resin. The temperature and time to disappear can easily be adjusted. For example, when the above-mentioned heat-destructible adhesive sheet is used in a process in which solder reflow is passed a plurality of times, since the conductive connection material portion fused to the electrode surface is re-melted for each reflow, the electronic component is not re-melted. There is a risk of deviation. For this reason, for example, by designing the heat extinguishing adhesive sheet so that it does not disappear at the temperature at the time of solder reflow, but disappears at a higher temperature, the electronic component is passed until it passes through several solder reflow steps. It can also be used suitably when it is desired to temporarily fix it.
[0013]
Examples of the crosslinkable silyl group include an oximesilyl group, an alkenyloxysilyl group, an acetoxysilyl group, a halogenosilyl group, a vinylsilyl group, and a silanol group. Among them, a polyoxyalkylene resin having an alkoxysilyl group at a terminal is preferable because it becomes a rubbery crosslinked resin having tackiness and excellent elasticity. Examples of the alkoxysilyl group include a methoxysilyl group, an ethoxysilyl group, a propyloxysilyl group, an isopropyloxysilyl group, a butoxysilyl group, a tert-butoxysilyl group, a phenoxysilyl group, and a benzyloxysilyl group. In the case of a dialkoxysilyl group or trialkoxysilyl group, they may be the same alkoxy group or a combination of different alkoxy groups. These crosslinkable silyl groups may be used alone or in combination of two or more. Further, a plurality of types of polyoxyalkylene resins having different types of polyoxyalkylene resins and different crosslinkable silyl groups may be used in combination.
[0014]
It is preferable that the polyoxyalkylene resin composition further contains a photoreaction catalyst having a functional group represented by the following formula (1). Thereby, the polyoxyalkylene resin composition can be rapidly crosslinked and cured by irradiating light such as visible light, ultraviolet light, or electron beam (hereinafter also referred to as light irradiation). Among them, carboxylic acid anhydrides, carboxylic acid imides and diacylphosphine oxides are preferred because of their high photoreactivity and excellent solubility in a polyoxyalkylene resin having a crosslinkable silyl group. Such photoreaction catalysts may be used alone or in combination of two or more.
