- a metal composite substrate having a metal layer of 12 m was obtained by the method described in Patent Document 3.
- Table 3 shows the evaluation results.
- Insulation resistance between lines: ⁇ ⁇ ⁇ 3 50 / ⁇ ⁇ , X: Cannot be measured because pattern cannot be formed Hygroscopic solder metathermal: D-2 / 100 + 60s / 280 ° C
