Description

本発明は、いろいろな部材を加工するに際しての仮固定方法であり、またそれに好適な接着剤に関するものである。より詳細には、本発明は、光学用部材を加工するに際して当該部材を仮固定する方法と、当該用途に好適な光硬化性接着剤に関する。 The present invention relates to a temporary fixing method for processing various members, and to an adhesive suitable for the method. More specifically, the present invention relates to a method of temporarily fixing the optical member when processing the optical member, and a photocurable adhesive suitable for the application.

従来から、光学レンズ、プリズム、アレイ、シリコンウエハ、半導体実装部品を加工する際に仮固定することが行われているが、その際に、仮固定用接着剤として両面テープやホットメルト系接着剤が使用されている。 Conventionally, when optical lenses, prisms, arrays, silicon wafers, and semiconductor mounting parts are processed, they are temporarily fixed. At that time, double-sided tape or hot-melt adhesives are used as temporary fixing adhesives. Is used.

つまり、前記のテープや接着剤にて部材同士或いは治具に部材を接合または積層し、部材を所定の形状に切削等の方法で加工後、前記テープや接着剤を除去し、加工部材を回収することが行われている。 In other words, the members are joined or laminated to each other or a jig with the tape or adhesive, and after processing the member into a predetermined shape by a method such as cutting, the tape or adhesive is removed and the processed member is recovered. To be done.

例えば、半導体実装部品については、これらの部品を両面テープにて基材に固定した後、所望の部品に加工を行い、更に両面テープに紫外線を照射することで部品からの剥離を行う。 For example, for semiconductor mounting components, these components are fixed to a substrate with a double-sided tape, then processed into a desired component, and further peeled off from the component by irradiating the double-sided tape with ultraviolet rays.

また、ホットメルト系接着剤の場合には、部材を積層後、加熱により間隙に接着剤を浸透させた後、所望の部品に加工を行い、有機溶剤中で接着剤の剥離を行う。 In the case of a hot-melt adhesive, after laminating the members, the adhesive is infiltrated into the gap by heating, and then processing is performed on a desired part, and the adhesive is peeled off in an organic solvent.

しかし、両面テープを用いる場合には、厚み精度を出すのが困難であったり、接着強度が弱いために部品加工時にチッピング性が劣ったり、100℃以上の熱をかけないと剥離できなかったり、紫外線照射で剥離させる場合には、被着体の透過性が乏しいと剥離できない等の問題があった。 However, when using a double-sided tape, it is difficult to obtain thickness accuracy, the chipping property is inferior at the time of component processing because the adhesive strength is weak, and it cannot be peeled off without applying heat of 100 ° C or higher, In the case of peeling by ultraviolet irradiation, there is a problem that peeling cannot be performed if the adherend has poor permeability.

また、ホットメルト系接着剤を用いる場合には、接着時に100℃以上に加熱しなければ貼ることができないことから、この方法が適用できる部材に制約があった。更に、剥離時に有機溶剤を使用する必要があり、アルカリ溶剤やハロゲン系有機溶剤の洗浄処理工程を採用する必要があり、煩雑であるし、作業環境的にも問題となっている。 In addition, when a hot melt adhesive is used, it cannot be applied unless it is heated to 100 ° C. or higher at the time of bonding, and thus there is a restriction on members to which this method can be applied. Furthermore, it is necessary to use an organic solvent at the time of peeling, and it is necessary to employ an alkali solvent or halogen-based organic solvent cleaning treatment step, which is complicated and problematic in terms of the working environment.

これらの欠点を解決するために、水溶性ビニルモノマー等の水溶性化合物を含有する仮固定用の光硬化型接着剤が提案されているが、これらの接着剤組成物では、水中での剥離性は解決されるのに対し、部品固定時の接着強度が低く、切削加工後の部材の寸法精度に乏しい課題がある(特許文献1、2、3参照)。

In order to solve these drawbacks, photocurable adhesives for temporary fixing containing a water-soluble compound such as a water-soluble vinyl monomer have been proposed, but these adhesive compositions have a peelability in water. However, there is a problem that the adhesive strength at the time of component fixing is low and the dimensional accuracy of the member after cutting is poor (see Patent Documents 1, 2, and 3).

切削加工後の部材の寸法精度を向上させるために、特に光学部品の用途分野では、接着強度が高く、しかも水中での剥離性に優れる接着剤が望まれている。 In order to improve the dimensional accuracy of the member after cutting, an adhesive having high adhesive strength and excellent releasability in water is desired particularly in the field of application of optical components.

本発明者は、従来技術の状況に鑑みていろいろ検討した結果、特定のアクリルモノマーを組み合わせることにより、接着強度が高く、しかも硬化後に水中での剥離性の良好な接着剤組成物を見出し、本発明に至ったものである。 As a result of various investigations in view of the state of the prior art, the present inventor has found an adhesive composition having high adhesive strength and good peelability in water after curing by combining specific acrylic monomers.

本発明の接着剤組成物は、その組成故に光硬化性を有し、可視光または紫外線によって硬化する。このために、従来のホットメルト接着剤に比べ、省力化、省エネルギー化、作業短縮の面で著しい効果が得られる。また、その硬化体は、高い接着強度を発現できるので、部材の加工時にずれを生じ難く、寸法精度面で優れた部材が容易に得られるという効果が得られる。更に、当該硬化体は、水、特に30℃以上の温水、に接触することで接着強度を低下させ部材間の或いは部材と治具との接合力を低下するので容易に部材の回収ができる特徴があり、従来の接着剤の場合に比べ、高価で、発火性の強い、或いは人体に有害なガスを発生する有機溶媒を用いる必要がないという格段の効果が得られる。更に、特定の好ましい組成範囲の接着剤組成物においては、硬化体が水、特に温水と接触して膨潤し、フィルム状に部材から回収できるので、作業性に優れるという効果が得られる。 The adhesive composition of the present invention is photocurable due to its composition and is cured by visible light or ultraviolet light. For this reason, compared with the conventional hot melt adhesive, a remarkable effect is acquired in terms of labor saving, energy saving, and work shortening. In addition, since the cured body can exhibit high adhesive strength, it is difficult to cause a shift during processing of the member, and an effect that a member excellent in dimensional accuracy can be easily obtained can be obtained. Furthermore, the cured body is characterized in that the adhesive strength is reduced by contact with water, particularly warm water of 30 ° C. or higher, and the bonding force between the members or between the member and the jig is reduced, so that the member can be easily recovered. As compared with the case of conventional adhesives, it is possible to obtain a remarkable effect that it is not necessary to use an organic solvent that is expensive, strongly ignitable, or generates a gas harmful to the human body. Furthermore, in the adhesive composition having a specific preferable composition range, the cured product swells upon contact with water, particularly hot water, and can be recovered from the member in the form of a film, so that the workability is excellent.

本発明の部材の仮固定方法は、前述した通りに、水に接触することで接着強度を低下させる接着剤を用いているので、水に接触させるのみで容易に部材の回収ができる特徴があり、従来の接着剤の場合に比べ、高価で、発火性の強い、或いは人体に有害なガスを発生する有機溶媒を用いる必要がないという格段の効果が得られる。 As described above, the temporary fixing method of the member of the present invention uses an adhesive that reduces the adhesive strength by contact with water. Therefore, the member can be easily recovered only by contacting with water. As compared with the case of the conventional adhesive, a remarkable effect is obtained that it is not necessary to use an organic solvent that is expensive, strong in ignition, or generates a gas harmful to the human body.
