Abstract: A printed circuit board includes a first insulating layer, a second insulating layer on the first insulating layer, and at least one via formed through the first and second insulating layers in a layered structure. The via includes a first via layer formed through the first insulating layer, a second via layer formed on the first via layer while passing through the second insulating layer, and an adhesive layer between the first and second via layers. The first via layer has a section different from a section of the second via layer. The adhesive property between the copper layer and the insulating layer is improved. The vias used to connect interlayer circuits to each other are formed between a plurality of insulating layers through an etching process instead of a laser process or a polishing process, thereby improving the process ability and reducing the manufacturing cost.

Abstract: A toaster having at least one toasting slot includes at least one sensor operative to generate a sensor signal indicating whether or not a food item is loaded in said slot and heating elements for generating heat energy to toast a food item loaded in the toasting slot by use of an electrical current. The toaster also includes at least one switching unit that is responsive to the sensor signal and operative to control the electrical current flowing through the heating elements such that the switching unit cuts off the electrical current when the slot is unloaded.
