    • A method of forming a conductor pattern, in which a conductor pattern formed on a support plate can be completely transferred from the support plate into a resin layer, and in which the step of roughening the surface of conductor pattern can be avoided to thereby attain reduction of production cost. In the method of forming a conductor pattern, there is provided conductor pattern (12) of overhung section having small-diameter part (12A) and large- diameter part (12B) superimposed on the superior surface of support member (100) sequentially from the superior surface toward vertical above. Subsequently, semi-hardened resin layer (110) is applied onto the support member (100), so that the conductor pattern (12) of overhung section is embedded in the resin layer (110), and the semi-hardened resin layer (110) is completely hardened. Thereafter, the resin layer (110) is detached from the support member (100) with the use of the large-diameter part (12B) of the conductor pattern (12) of overhung section as an anchor, so that the conductor pattern (12) of overhung section is transferred from the support member (100) into the resin layer (110).

    • The present disclosure generally relates to a shielded three-layer patterned ground structure in a PCB. The PCB may be disposed in a hard disk drive. Conductive traces in PCBs can have the problem of common mode current flowing through the traces and thus increasing the magnitude of EMI noise. By providing a shielded three-layer patterned ground structure, not only is the cost reduced, but so is the common mode current and the magnitude of EMI noise, all without any negative impact to the differential signal. The PCB (400) comprises a first shield layer (302) comprising a first conductive material; a second shield layer (304) that is spaced from the first shield layer by a first dielectric material, wherein the second shield layer comprises a second conductive material, wherein the second shield layer has a main portion and a first patterned ground structure (314), wherein the first patterned ground structure is spaced from the main portion on all sides by a moat (316) that is filled with a second dielectric material when viewed from a top view; a third shield layer (306) disposed over the second shield layer and spaced from the second shield layer by a third dielectric material, wherein the third shield layer comprises a first portion and a second portion, wherein the first portion and the second portion are each disposed over the moat when viewed from the top view; and a first set of traces (308) disposed between the first portion and the second portion.
