Description

本発明は、プリント配線基板等の実装工程に用いられる印刷用メタルマスク版に関するものである。
The present invention relates to a printing metal mask plate used in a mounting process of a printed wiring board or the like.

現在、プリント配線基板等の基板回路形成には金属の板に印刷パターンが開口されたメタルマスク(以下マスク)が一般的に用いられている。
Currently, a metal mask (hereinafter referred to as a mask) in which a printed pattern is opened in a metal plate is generally used to form a substrate circuit such as a printed wiring board.

前記したマスクを用いて基板上に導電性ペースト(以下ペースト)を印刷する場合にはスクリーン枠と呼ばれる金属製の枠、もしくは硬質の樹脂製の枠に前記マスクを張設した所謂メタルマスク版と呼ばれる形状で印刷装置にセットして印刷するのが一般的である。
When printing a conductive paste (hereinafter referred to as paste) on a substrate using the above-described mask, a metal frame called a screen frame, or a so-called metal mask plate in which the mask is stretched on a hard resin frame, and In general, it is set in a printing apparatus in a so-called shape and printed.

前記メタルマスク版を用いた印刷方法としては、メタルマスク版を基板から離して水平に載置し、マスク上からスキージを基板方向に押し付けながら移動させることにより、開口内に半田ペーストを充填し、スキージが通り過ぎた時点でペーストを基板接触部に載せていきながら基板上に半田を印刷する方法、所謂オフコンタクト印刷が一般的に行われている。
As a printing method using the metal mask plate, the metal mask plate is placed horizontally apart from the substrate, and the solder paste is filled in the opening by moving the squeegee while pressing it toward the substrate from the mask, A method of printing solder on a substrate while placing a paste on the substrate contact portion when the squeegee passes, so-called off-contact printing is generally performed.

メタルマスク版としては、枠に直接マスクを張設した版、所謂フルメタル版と、紗と呼ばれるメッシュスクリーンを介して枠にマスクを張設した所謂コンビネーション版がある。
As the metal mask plate, there are a plate in which a mask is directly stretched on a frame, a so-called full metal plate, and a so-called combination plate in which a mask is stretched on a frame via a mesh screen called a ridge.

フルメタル版は、マスクを直接枠に張設できるため、張設の手間がかからないという利点がある。しかし、マスクの材質である金属の特性上、印刷時にマスクが伸びてしまい、印刷パターンの寸法精度が変化しやすいという欠点がある。
The full metal version has an advantage that the mask can be directly stretched on the frame, so that the labor of stretching is not required. However, due to the characteristics of the metal that is the material of the mask, there is a drawback in that the mask stretches during printing and the dimensional accuracy of the printed pattern is likely to change.

前記問題を踏まえて開発されたのがコンビネーション版であり、印刷時に生じてしまうマスクの伸びを弾性のあるスクリーンメッシュで吸収させることにより、フルメタル版と比べ、印刷耐久性が格段に向上した。
特開2004−167713
The combination plate was developed based on the above problems, and the printing durability was remarkably improved as compared with the full metal plate by absorbing the elongation of the mask generated during printing with an elastic screen mesh.
JP 2004-167713 A

しかし、コンビネーション版は製造に手間がかかり、さらに耐久性を必要としない場面、例えば試作パターンの検討の際には、意匠パターンごとに専用の版を作製しなければならず、費用や手間がかかるという問題や、紗のテンションに起因する意匠パターンずれ、すなわちマスクが紗によって外側に引っ張られてしまい意匠パターンがずれてしまう問題があった。
However, the combination plate takes time to manufacture, and moreover, in the case where durability is not required, for example, when examining a prototype pattern, it is necessary to create a dedicated plate for each design pattern, which is expensive and time-consuming. There is a problem that the design pattern shifts due to the wrinkle tension, that is, the design pattern shifts because the mask is pulled outward by the wrinkles.

また、前記コンビネーション版を用いて印刷を行う場合、図7及び8に示したように印刷箇所によってはスキージによって押圧しながら印刷する際、マスクと基板の角度が異なってしまうため、スキージによるペーストの掻きとり量、すなわち基板面内の印刷状態にムラがでてしまうという問題があった。さらに版のテンションによってはスキージが通り過ぎた後、基板から紗が離れる、所謂版離れ時に均一な版離れができないという問題もあった。
Also, when printing using the combination plate, as shown in FIGS. 7 and 8, when printing while pressing with a squeegee depending on the printing location, the angle between the mask and the substrate will be different. There was a problem that the amount of scraping, that is, the printed state within the substrate surface, was uneven. Furthermore, depending on the tension of the plate, after the squeegee passes, the wrinkle is separated from the substrate, so that there is a problem that uniform plate separation cannot be performed at the time of so-called plate separation.

テンションをかけない版で印刷しようとする場合はマスクと基板を密着させて印刷するオンコンタクトと呼ばれる方法で印刷することになるが、その場合は逆にテンションをかけていないため、版離れ時にマスクがペーストの粘性によって引っ張られてしまい、マスクがうまく基板から剥がせずに意匠ズレが起きてしまうという問題がある。
When printing with a plate that does not apply tension, printing is performed by an on-contact method, in which the mask and the substrate are in close contact with each other. In this case, however, no tension is applied. However, it is pulled by the viscosity of the paste, and there is a problem that the design is displaced without the mask being peeled off from the substrate.

また、前記した試作パターンの検討の際には、通常、製品作製に使用している印刷装置よりも小さいスケール、できれば手作業によって費用や手間をかけずに簡易的に意匠パターンの評価が行なえることが望まれていた。
Also, when examining the above-mentioned prototype pattern, it is usually possible to easily evaluate a design pattern with a smaller scale than that of a printing apparatus used for product production, preferably without manual labor and cost. It was hoped that.

本発明は、意匠パターンの試作検討や、多品種少量生産を行う際に、メタルマスクを枠へテンションをかけずに張設でき、かつ手動で印刷する場合でも均一印刷性に優れた印刷版を得ることができることを目的とする。
The present invention provides a printing plate that is capable of stretching a metal mask without applying tension to a frame when performing trial manufacture of design patterns and producing a variety of products in small quantities, and is excellent in uniform printability even when printing manually. It aims to be obtained.

Although the plate separation speed can be improved by increasing the contact angle between the printing plate and the substrate of the present invention, the optimum condition varies depending on the paste type, squeegee speed, etc. It is desirable to adjust.

Examples of the material of the stencil of the present invention include metal materials such as Ni, Ni alloys, and SUS materials conventionally used for metal masks, and resin materials such as polyimide.

本発明の印刷版、及び基板を載置する受け台にはそれぞれ滑り止めが設けられていることが望ましく、滑り止めの形状としては、上下が噛み合わせ形状となっているギア状や、摩擦係数の高い形状のものが挙げられるが、印刷時の横ずれ防止を言う点を考慮すると、上下が噛み合わせ形状となっているギア状であることが望ましい。
The printing plate of the present invention and the cradle on which the substrate is placed are preferably provided with anti-slip, and the anti-slip shape includes a gear shape in which the top and bottom are meshed, and a friction coefficient However, considering the prevention of lateral displacement during printing, it is desirable that the upper and lower gears have a meshed shape.

また、基板受け台には枠ガイドを設けることにより印刷時に印刷版の横ずれを防止することができる。前記横ずれ防止の滑り止めは枠ガイドの上に設けてもよい。
Further, by providing a frame guide on the substrate cradle, it is possible to prevent a lateral displacement of the printing plate during printing. The slip prevention for preventing the lateral slip may be provided on the frame guide.
