摘要:
A core material-including organic core board or inorganic sintered board 1 having a plurality of band-shaped conductor patterns 2 formed on its front and rear surfaces is sliced in a direction crossing the band-shaped conductor patterns 2. End portions of the band-shaped conductor patterns 2 exposed on each of cut surfaces of the core board 1 are connected to one another by bridging conductor patterns formed on the cut surfaces. In this manner, at least one helical coil is provided. The inner diameter of the helical coil can be kept constant while coil pitch accuracy can be kept good.

This invention has an object of providing a method for producing a multilayer substrate or an electronic part wherein decrease in the thickness has been enabled without causing the problem of insufficient strength or the like in the handling, as well as the electronic part. Such object has been attained by a method for producing a multilayer substrate or an electronic part comprising the steps of adhering a conductor layer to a transfer film, patterning the conductor layer to form a predetermined pattern, placing the transfer film overlaid with the patterned conductor layer on a prepreg so that the side of the conductor layer faces the prepreg, and then adhering the transfer film to the prepreg by applying heat and pressure and peeling the transfer film to produce the prepreg having the conductor layer formed thereon; and the multilayer electronic part produced by such method.
摘要:
A laminated electronic component including at least one inductance element and produced from a laminate having electrical insulators and electrical conductors laminated alternately. The inductance element is formed as a helical coil having a plurality of turns each constituted by four sides. The inductance element has pairs of parallel conductor pieces and pairs of bridging conductor pieces. Each pair of parallel conductor pieces form two of the four sides of one turn of the coil. Each pair of bridging conductor pieces form the other two sides of one turn of the coil. Grooves are formed in the laminate to thereby form the parallel conductor pieces. The grooves are filled with an electrically insulating material. The bridging conductor pieces are formed on the electrically insulating material.
