A degradable EVOH high-barrier composite film, characterized in that the materials of various layers in the composite film all obtain approximately-consistent biodegradability by introducing biomass, and the additive amount of the additive master batch in the materials of each layer is controlled within the range of 0.3-15% of the total mass of the materials of the corresponding layer; the hydrophilic activity of the hydrophilic groups in the additive master batch should be greater than or equal to that of the hydrophilic groups in the materials of each layer; by adding the additive master batch, the mole ratios of the hydrophilic groups to carbon atoms of the materials of various layers tend to be consistent, namely, the bioactivities tend to be consistent, so that the degradation rates of the materials of various layers in the composite film tend to be consistent. The present invention makes contribution to obtaining approximately-consistent bioactivities and approximately-consistent biodegradation rates by balancing the mole ratios of the hydrophilic groups to carbon atoms in the materials of various layers, and the appearance, the functions and the physical and mechanical properties of a product remain unchanged.

Multilayer circuit board manufacturing method

There is a method of manufacturing a multilayer wiring board including: alternately stacking wiring layers and insulating layers; stacking a reinforcing sheet on one surface of the resulting multilayer laminate with a soluble adhesive layer therebetween, wherein an unoccupied region without the soluble adhesive layer is provided within a facing area where the reinforcing sheet faces the multilayer laminate; allowing a liquid capable of dissolving the soluble adhesive layer to infiltrate the unoccupied region to dissolve or soften the soluble adhesive layer; and releasing the reinforcing sheet from the multilayer laminate at the soluble adhesive layer. This method enables the multilayer wiring layer to be reinforced to generate no large local warpage, thereby improving the reliable connection and the surface flatness (coplanarity) of the multilayer wiring layer. The used reinforcing sheet can be released in a significantly short time, while minimizing the stress applied to the multilayer laminate.
