Polyimide film and stiffener for flexible circuit board using the same |
| abstract |
Provided is a polyimide film having improved punchability by suppressing generation of burrs and chips in a punching process, and a stiffener for a flexible circuit board using the polyimide film. When the thickness is 120 μm or more, the variation width of the tear strength is d (N / mm), and the average of the tear strength is F (N / mm), R represented by the formula 1 is 35. % Or less. R (%) = (d / F) × 100 (formula 1) [Selection diagram] None |
