- the predetermined through-holes and via-holes are drilled with a drill and a laser, and then the surface of the roughening resin composition is roughened with a permanganate alkaline oxidizing agent. After forming a conductor layer on the entire surface by electroless and electrolytic plating, a multilayer printed wiring board was obtained according to a subtractive method.
- This multilayer printed wiring board had a conductor vial strength of 1.0 kg / cm after annealing at 100 ° C. for 60 minutes.
- the modulus of elasticity of the insulating layer determined from the universal hardness tester was 4.8 GPa at room temperature and 0.150. It was 3. l GPa in C. Comparative Example 3
- Example 1 The resin varnish in Example 1 was treated with a polyimide film treated with double-sided plasma treatment as in Example 1 (“UPILEX S” manufactured by Ube Industries, Ltd. (thickness: 12.5). m)) On top, apply it with Daiko Yuichi so that the resin thickness after drying becomes 60 m, and dry at 80 to 120 ° C (average 100 ° C) for 2 minutes (residual The amount of the solvent was about 10% by weight), and a 15- ⁇ m-thick polypropylene film was stuck on the surface of the dried thermosetting resin composition and wound up in a roll shape.
- the roll-shaped adhesive film was slit into a width of 507 mm to obtain a sheet-like adhesive film having a size of 507 ⁇ 336 mm.
- the layer structure of the obtained adhesive film is a propylene film layer (protective film layer) Z thermosetting resin composition layer polyimide film layer (heat resistant resin layer).
- the adhesive film having the thermosetting resin composition layer was applied to a glass epoxy circuit board (conductor thickness: 35 ju) having a thickness of 0.4 mm and a size of 5100 X 340 mm in the same manner as in Example 5. Sheets were formed on both sides of the substrate with the resin composition side as the circuit side. Next, using “Vacuum Lamine Ichiichi MVLP” manufactured by Meiki Seisakusho Co., Ltd., a vacuum of 1 mbar (0.75 mmHg), a temperature of 100 ° C, and a pressure of 6 kg / cm 2 was applied. After pressing for two seconds and laminating both sides simultaneously, the laminated circuit board was heat-cured at 120 ° C for 30 minutes and further at 170 ° C for 30 minutes.
- thermosetting resin composition layer becomes non-uniform, and bubbles are generated in the thermosetting resin composition, so that a good insulating layer cannot be formed.
- Example 1 The resin varnish in Example 1 was placed on a polyimide film (upilex S (12.5 ⁇ m) manufactured by Ube Industries, Ltd.) that had been subjected to plasma treatment on both sides in the same manner as in Example 1, and dried. Coat with Daiko overnight so that the thickness becomes 60 // m, and dry at 80 to 120 ° C (average 100 ° C) for 15 minutes (residual solvent amount 1 wt% or less), and dry A 15-zm-thick polypropylene film is applied to the surface of the thermosetting resin composition after It was wound up in a roll while bonding. The roll-shaped adhesive film was slit into a width of 507 mm to obtain a 507 X 336 mm sheet-shaped adhesive film.
- upilex S (12.5 ⁇ m) manufactured by Ube Industries, Ltd.
- the layer structure of the obtained adhesive film was polypropylene film layer (protective film layer) / thermosetting resin composition layer / polyimide film layer (heat-resistant resin layer).
- thermosetting resin composition layer was applied to a glass epoxy circuit board (conductor thickness 35 m) having a thickness of 0.4 mm and a size of 510 x 340 mm in the same manner as in Example 5, and the surface of the thermosetting resin composition was Was used as the circuit side, and the sheets were formed on both sides of the substrate.
- a glass epoxy circuit board conductor thickness 35 m
- thermosetting resin composition was Was used as the circuit side, and the sheets were formed on both sides of the substrate.
- Ltd. Meiki manufactured by "vacuum laminator MVLP", vacuum 1 mbar (0. 75 mmHg), temperature 100 ° C, and pressed for 15 seconds under a pressure of 6 kg / cm 2, both surfaces simultaneously After lamination, the laminated circuit board was thermally cured at 120 ° C. for 30 minutes and further at 170 ° C. for 30 minutes.
- ADVANTAGE OF THE INVENTION when manufacturing a multilayer printed wiring board by the build-up method, it is possible to obtain an adhesive film that can easily introduce an insulating layer having excellent mechanical strength, and further obtain a multilayer having excellent mechanical strength. A printed wiring board can be easily obtained.
