    摘要: One of a plurality of capacitors embedded in a printed circuit structure includes a first electrode (415) overlaying a first substrate layer (505) of the printed circuit structure, a crystallized dielectric oxide core (405) overlaying the first electrode, a second electrode (615) overlying the crystallized dielectric oxide core, and a high temperature anti-oxidant layer (220) disposed between and contacting the crystallized dielectric oxide core and at least one of the first and second electrodes. The crystallized dielectric oxide core has a thickness that is less than 1 micron and has a capacitance density greater than 1000 pF/mm2. The material and thickness are the same for each of the plurality of capacitors. The crystallized dielectric oxide core may be isolated from crystallized dielectric oxide cores of all other capacitors of the plurality of capacitors.

    摘要: A technique for fabricating a patterned resistor on a substrate produces a patterned resistor (101, 801, 1001, 1324, 1374) including two conductive end terminations (110, 810, 1010) on the substrate, a pattern of first resistive material (120, 815, 1015) having a first width (125) and a first sheet resistance, and a pattern of second resistive material (205, 820, 1020) having a second width (210) and a second sheet resistance that at least partially overlies the pattern of first resistive material. One of the first and second sheet resistances is a low sheet resistance and the other of the first and second resistances is a high sheet resistance. A ratio of the high sheet resistance to the low sheet resistance is at least ten to one. The pattern having the higher sheet resistance is substantially wider than the pattern having the low sheet resistance. The patterned resistor can be precision trimmed 1225.

    摘要: A method is for fabricating an embedded capacitance printed circuit board assembly (400, 1100). The embedded capacitance printed circuit board assembly includes two embedded capacitance structures (110). Each capacitance structure (110) includes a crystallized dielectric oxide layer (115) sandwiched between an outer electrode layer (120) and an inner electrode layer (125) in which the two inner electrode layers are electrically connected together. A rivet via (1315) and a stacked via (1110) formed from a button via (910) and a stacked blind via (1111) may be used to electrically connect the two inner electrode layers together. A spindle via (525) may be formed through the inner and outer layers. The multi-layer printed circuit board may be formed from a capacitive laminate (100) that includes two capacitance structures.

    摘要: A textured dielectric panel (305, 520, 625, 745, 925, 1035, 1205) is fabricated by applying a first mask pattern (310, 510, 610, 710, 915, 1015, 1210) to a first side of a solid panel made of a first material that is a ceramic dielectric and then sandblasting the solid panel through the first mask pattern from the first side to at least partially generate a shaped cavity (315, 920, 1040). The shaped cavity of the solid panel may be filled with a-second material (330, 740). The first and second materials have substantially differing dielectric constants. The first side and second side of the solid panel may be metallized (325), forming a patch antenna. The shaped cavities can be made more complex by using additional masking and/or sandblasting steps.
