发明名称 Method for adjusting capacitor at manufacture and product
摘要 A method for making multilayer ceramic capacitors (MLC) has two phases, namely a first test phase and a second manufacturing phase. A test MLC capacitor with buried overlapping electrodes is made and the capacitance of that test capacitor is measured. In the subsequent manufacturing phase the same process is used to make the same capacitor except adding to it at least one pair of coplanar electrodes whereby the small capacitance between each pair of coplanar electrodes is parallel connected with the base capacitor to bring the total capacitance up close to a target value. This method is particularly valuable for making close tolerance capacitors having only a few conventional overlapping electrodes, because each pair of coplanar capacitance-adjusting electrodes has a relatively small, stable, predictable incremental capacitance that is insensitive to changes in registration between successive electrodes.
