CHIP RESISTOR FOR SURFACE MOUNTING AND ITS SURFACE-MOUNTING METHOD

摘要

PURPOSE: To radiate heat generated in a resistor from the entire surface of a resistor support and to suppress the temperature increase of parts by burying the resistor into the resistor support consisting of an insulator and providing the electrode of the resistor at both side parts of the resistor support. CONSTITUTION: A resistor 2 consisting of copper or ruthenium oxide is covered so that it is sandwiched from upper and lower portions by a resistor support 1 consisting of an insulating material such as ceramic and at the same time an electrode 3 of the resistor 2 intrudes the upper resistor support 1 and is arranged at both sides, thus constituting a chip resistor. This sort of chip resistor is manufactured by printing and baking a resistor paste on the lower resistor support 1 consisting of the insulating material for forming a resistor 2 and then laminating an insulating material which becomes the upper resistor support 1 and at the same time arranging the electrode 3, thus suppressing the temperature increase of parts and at the same time improving the reliability of the parts and miniaturizing the parts and improving the yield.
