トパターン形成工程に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for manufacturing a printed wiring board, and is suitable for a printed wiring board that provides peace of mind in forming a highly accurate solder resist pattern after forming a conductor pattern on a load. The present invention relates to a solder resist pattern forming process.

のソルダーレジストによる。After forming conductor patterns and through-holes on an insulating board, the printed board manufacturing method requires highly accurate solder resist pattern formation.A photosensitive solder resist is used on the entire surface of the printed board, and the desired pattern is formed using a photographic method. The solder resist film was subjected to curing treatment such as heating as necessary. For example, electronic technology June 1985 special issue P114-115 published by Nikkan Kogyo Shimbun.

ソルダーレジスト残りが発生する問題があった。In the conventional technology, when exposing a solder resist pattern, for example, light goes around to the opposite side through the transparent part of the mask film on the exposed surface, the photosensitive resist, and the glass cloth base epoxy resin plate of the insulating plate. Unnecessary areas are cured and developed: aJ! lt& also had the problem that solder resist remained in one of these places.

ーン形成を行うことにより達成される。The above object is achieved by applying a photosensitive solder resist only to the high-density pattern area and forming the pattern using a photographic method, and forming the solder resist pattern at other areas by screen printing.

低域にも役立つ。Unless there are two or more layers of high density in the same place on both sides of the outer layer of the printed board, a photosensitive solder resist is applied only to the high density pattern area, and the pattern is formed using a photographic method. Other low-density areas can be adequately covered by screen printing, so the conventional problem of light wrap-around during exposure is now a problem (which cannot be treated) as shown in Figure 2. However, only in high-density areas,
Because it uses a photosensitive solder resist, it also helps lower the price of printed circuit boards.

After exposing both sides of the film 7 and removing the film mask 7, a pattern is formed by exposure. After this, the film is hardened using Calo heat, etc., to form a strong solder resist.

膜を強化させる。FIGS. 1 and 2 are examples of actual images of the present invention. After pretreatment in the same manner as before, a photosensitive solder resist 1 is applied to one side, a film mask 7 is applied, and exposure is made. And film mask 7'f! : After removing and developing, a pattern of solder resist 6 is formed on the other side by screen printing, and post-treatment such as heating is performed to strengthen the solder resist film.
ソルダーレジスト６は、後処理で加熱して硬化する場合

パターン形成する方法もできることは言うｆでもない。Further, even if the photosensitive solder resist is used, as long as it is thermally cured, the post-treatment may be performed using Gallo heat. However, if heat curing is not required, post-processing that combines "full-surface exposure and heating with light Q It goes without saying that other patterns can also be formed by screen printing.

リント板を比較的安両に製造することができる。According to the present invention, a photosensitive solder resist is applied only to the high-density pattern area, and the relatively low-density pattern area cannot be covered by screen printing. Compared to when I did x iIa,
Printed boards can be manufactured relatively cheaply because the cost of solder resist and the number of man-hours are reduced.

ルダーレジスト仕上り品質がよくなる。Also, unless a high-density solder resist pattern is required at the same location on both sides of the outer layer of the printed board, the pattern is formed on the opposite side of the side to which the photosensitive solder resist is applied by screen printing. Therefore, even if light reaches the exposed surface during exposure or the opposite surface through a via hole,
Unlike the conventional method, the solder resist on the opposite side is photocured up to the thighs, and there is no residual resist, so the quality of the solder resist finish is improved.
