Patent ID: 11825632

Abstract:
The present invention provides a thermally conductive insulating sheet having appropriate fluidity upon being heated and pressurized, and free from of the possibility of a material leaking to the outside beyond the original size of the sheet. The thermally conductive insulating sheet according to the present invention contains an uncured material and/or a semi-cured material of a binder resin (R) which is a thermosetting resin. In the present invention, a complex viscosity in a temperature range of 100-200° C. is 10,000-150,000 Pa·s, a ratio (α/β) of the maximum value (α) to the minimum value (β) of the complex viscosity in said temperature range is 1.0-4.0, and the flow value is 90-100%. Flow value(%)=W2/W1×100.
