- the Tg, copper foil peel strength, solder heat resistance and water absorption of the obtained copper-clad laminate with inner layer circuit were examined. Tables 1 and 2 show these results.
- T g Copper foil is etched and measured by TMA (thermomechanical analysis) (unit: C). Copper foil peeling strength: A line with a width of 1 O mm was formed on a substrate by etching, and the peeling strength in a vertical direction was measured with a bow
- the copper foil peeling strength was as high as 1.5 kNZm under normal conditions, and also maintained at about 50% of the normal peeling strength even at 200 ° C. Deterioration is small. Further, in Examples 1 to 8, since phenol nopolak is used as a curing agent, it has a high Tg of about 140 to 175 ° C, and has good solder heat resistance and low water absorption. On the other hand, in Comparative Examples 1 and 2, the copper foil peeling strength at normal conditions and at 200 ° C. was low. Comparative Examples 3 and 4 in which phenol novolak was not used as the curing agent were inferior in heat resistance. Comparative Example 5 using dicyandiamide has a low Tg and a low copper foil peeling strength at 200 ° C. Higher water absorption and solder resistance Poor heat.
- Brominated bisphenol ⁇ type epoxy resin (Sumiepoxy ESB400T: trade name, manufactured by Sumitomo Chemical Co., Ltd., epoxy equivalent 400, bromine content 49% by weight) 100 parts by weight and phenolite VH- 41 70 20.2 parts by weight, phenolite 9.3 parts by weight of LA—7054 and 43.3 parts by weight of YPB—40 were dissolved in methylethyl ketone.
- a curing accelerator 0.3 part by weight of 1-cyanoethyl-12-ethyl-4-methylimidazole was blended to prepare a varnish having a nonvolatile content of 60% by weight.
- the varnishes obtained in Examples 9 to 16 and Comparative Examples 6 to 7 were applied to a copper foil having a thickness of 0.018 mm, and heated at 160 ° C. for 3 minutes to obtain an adhesive layer having a thickness of 50 ⁇ .
- a copper foil with an adhesive having an adhesive was obtained.
- the obtained copper foil with adhesive is layered on both sides of a printed wiring board (MCL E-679: trade name of Hitachi Chemical Co., Ltd.) with a thickness of 0.4 mm and a circuit formed in advance.
- a copper-clad laminate with an inner layer circuit was produced under a press condition of 175 ° C., 90 minutes, and 2.5 MPa.
- the obtained copper-clad laminate with inner layer circuit was examined for Tg, copper foil peeling strength, solder heat resistance, water absorption, and heat discoloration. Tables 3 and 4 show these results.
- Tg, copper foil peel strength, solder heat resistance, and water absorption are the data described above.
- Table 4 shows the results of the heat discoloration test performed as follows.
- Example 9 the heat discoloration was visually evaluated after etching the copper foil and treating it at 160 ° C. for 5 hours in the air. Those with no discoloration were marked with ⁇ , those with slight discoloration as ⁇ , and those with discoloration as X.
- the copper foil peeling strength was as high as 1.5 kNZm in the normal state, and the peel strength was about 50% of the normal state even at 200 ° C. Deterioration at high temperatures is small. Examples 9 to 16 have a high T g of about 140 to 180 ° C.
- Comparative Examples 6 and 7 have a low copper foil peeling strength at normal conditions and at 200 ° C.
- the adhesive-coated copper foil according to the present invention has low hygroscopicity, has excellent heat resistance, has good adhesiveness with vigorous copper foil, and can be laminated with an inner circuit board on the adhesive-coated copper foil.
- a copper-clad laminate having excellent properties can be obtained, and if a circuit is processed on the copper-clad laminate, a printed wiring board having excellent characteristics can be obtained.
