Abstract: A printed circuit board includes: a first insulating layer; a first cavity disposed in one surface of the first insulating layer; a plurality of protrusion portions spaced apart from each other in the first cavity; and a first wiring layer embedded in the one surface of the first insulating layer.

Abstract: A printed circuit board includes: an insulating layer; a plurality of pads disposed on the insulating layer; and a plurality of insulating walls disposed on the insulating layer, and at least partially covering side surfaces of the plurality of pads, respectively, while being free from surfaces of the plurality of pads, respectively. The plurality of insulating walls are disposed to be spaced apart from each other on the insulating layer.

Abstract: The present invention relates to a bio-implantable bladder treatment device, and a method for manufacturing an electronic web and an electronic thread included therein. The bio-implantable bladder treatment device according to an embodiment of the present invention includes: an electronic web which is installable to cover the outer circumference of the bladder; and an electronic thread inserted into the electronic web to be coupled to the electronic web and configured to measure a state of the bladder.

Abstract: The present invention relates to a degradable substrate for an electronic device, a degradable substrate assembly for an electronic device, and a method for manufacturing a degradable substrate for an electronic device. The degradable substrate for an electronic device according to an embodiment of the present invention comprises: a substrate base material which is a polymer material; and a degradable foam-generating material which is in the form of particles uniformly mixed with the substrate base material and generates foam by reacting with water.
