ンドに配置してはんだ付けを行う。BACKGROUND OF THE INVENTION Printed wiring boards are used to mount a large number of electronic components, and are widely used in the electronic industry. When manufacturing this printed wiring board, for example, an etching resist ink is applied to the copper surface of a copper-clad laminate, cured according to the wiring pattern, the uncured portion is removed, and the exposed copper surface is etched. Then, when the cured coating is removed, a printed wiring board is completed. When using this printed wiring board, the entire surface of the printed wiring board is covered with insulating solder resist ink, except for the lands, and then the electronic components are placed on the lands for soldering. Perform soldering.

を行うものである。この印刷枚数が数百にもなると、ス
クリーンにインクが詰まるので洗浄溶剤でこのインクを
熔解除去し、再度同様にスクリーン印刷を行う。Such etching resist ink and solder resist ink are applied by screen printing. Screen printing is a process in which a urethane rubber squeegee coated with ink is pressed against a screen made of a polyester mesh having an ink-permeable area and an ink-impermeable area, thereby printing on the surface to be coated. When the number of printed sheets reaches several hundred, the screen becomes clogged with ink, so the ink is dissolved and removed using a cleaning solvent, and screen printing is performed again in the same manner.
このスクリーン印刷の際、スクリーン、インク及びウレ
タンゴムスキージは帯電し易く、静電気を帯び易い。During this screen printing, the screen, ink, and urethane rubber squeegee are easily charged and charged with static electricity.
このように静電気を帯びると、エツチング用しジス日臭

塗布されたインクが引っ張られて硬化塗膜の必要部分が
露出して後の工程でエツチングされ断線を生じることが
ある。If the ink is charged with static electricity, dirt and dust in the air will be sucked into the ink during etching, and this part will remain with the cured coating and will not be etched in later steps. Wiring may be short-circuited, or the ink applied to the screen may be pulled, exposing a necessary portion of the cured coating and etching in a later process, resulting in disconnection.
ソルダーレジストインクの場合についてもホコリやゴミ

。In the case of solder resist ink, there are also problems such as poor insulation performance due to dust and dirt being sucked in or the ink applied to the screen being pulled.

コリ等の少ないクリーンルームで各工程の処理が行われ
ているがこれでも不十分である。In particular, the density of printed wiring boards has rapidly increased in recent years, and the wiring spacing of wiring patterns has become narrower, for example, Q, 1 mm, making it easier for problems due to static electricity to occur when applying the above-mentioned resist ink. Therefore, when manufacturing high-quality printed circuit boards with such narrow wiring spacing, each process is performed in a clean room with little dust, but even this is insufficient.
発明が解決しようとする課題
現在、レジストインク塗布の際に生じる静電気を除去す
るために、静電防止ブラシを使用し、発生した静電気を
このブラシを近づけることにより除去している。Problems to be Solved by the Invention Currently, in order to remove static electricity generated when applying resist ink, an antistatic brush is used, and the generated static electricity is removed by bringing the brush close to the resist ink.
しかしながら、このように印刷の都度これを行うのは作
業が煩わしく、作業能率上問題がある。However, doing this every time printing is cumbersome and poses problems in terms of work efficiency.
本発明の目的は、静電防止ブラシを使用することなく、

After this,
Similarly, 100 sheets were printed, but no short-circuit due to adhesion of dust or ink gaps was observed. Similarly 0.2On
400 sheets were printed using a screen with line spacing, and then washed in the same manner with the above-mentioned ink cleaning agent, and 400 sheets were printed again, but no dust was observed or short circuits due to ink gaps were observed.

ことができる。Effects of the Invention According to the present invention, since the resist ink and its cleaning agent contain an antistatic agent, when screen printing is performed using the former, or when a screen is cleaned and printed using the latter, the ink becomes antistatic. properties and prevents the generation of static electricity. Thereby, short circuits between wirings can be eliminated when manufacturing a printed circuit board with high wiring density, and the insulation performance can be maintained at a high level when forming a solder resist film.
