Description
【0019】
弱粘着層12は、弱い粘着力で銅箔に貼着される層で、粘着性、耐熱性、耐薬品性、離型性に優れた樹脂で構成される。粘着力は通常の粘着剤に比べかなり弱いことが好ましい。具体的には、通常の粘着剤の剥離強度は400〜1000gf/25mm幅程度であるが、本発明の弱粘着層は剥離強度(JIS Z-0237)が100gf/25mm幅以下で、好適には1〜20gf/25mm幅とする。このような範囲とすることにより、導体パターン形成工程において銅箔から剥離することなく銅箔を保護することができ、しかも熱プレス後、銅箔表面に残ることなく容易に剥離することができる。[0019]
The weak adhesive layer 12 is a layer that is attached to the copper foil with weak adhesive strength and is made of a resin that has excellent adhesiveness, heat resistance, chemical resistance, and mold releasability. It is preferable that the adhesive strength be significantly weaker than that of ordinary adhesives. Specifically, while the peel strength of ordinary adhesives is approximately 400 to 1000 gf/25 mm width, the weak adhesive layer of the present invention has a peel strength (JIS Z-0237) of 100 gf/25 mm width or less, preferably 1 to 20 gf/25 mm width. By setting the peel strength within this range, the copper foil can be protected without peeling from the copper foil during the conductor pattern formation process, and further, it can be easily peeled off without remaining on the copper foil surface after hot pressing.

この多層プリント配線板製造用シートを用い、実施例1と同様に4層の多層プリント配線板を作製したところ、現像液、エッチング液、剥離液に侵されることなく、銅箔の保護ができた。しかし、ポリオレフィンフィルムに耐熱性がないために熱プレスによる積層時に熱による変形を起こしてしまった。[0039]
Using this sheet for manufacturing a multilayer printed wiring board, a four-layer printed wiring board was produced in the same manner as in Example 1. The copper foil was protected without being affected by the developer, etching solution, or stripping solution. However, because the polyolefin film lacked heat resistance, deformation due to heat occurred during lamination by hot pressing.

この多層プリント配線板製造用シートを用い、実施例1と同様に4層の多層プリント配線板を作製したところ、現像液、エッチング液、剥離液に侵されることなく、銅箔の保護ができた。しかし、熱プレスによる積層時、スルーホール部分からプリプレグがはみ出し、後工程で修正する問題が発生した。[0042]
Using this sheet for manufacturing a multilayer printed wiring board, a four-layer printed wiring board was produced in the same manner as in Example 1. The copper foil was protected from the developer, etching solution, and stripping solution. However, during lamination by hot pressing, the prepreg protruded from the through-hole area, which was a problem that had to be corrected in a later process.
