摘要： A multi-layer circuit such as for a disk drive suspension has two regions: a supported region in which first and second stacked signal conductors are supported on a stainless steel support layer and an insulating layer, and an unsupported region having flying leads in which the flying leads are not supported below by the support layer. The two stacked signal conductors are formed by two separate plating operations, the two plating operations simultaneously creating the flying leads and the unsupported portions of the signal conductors, such that the flying leads have thicknesses that are the sum of the thicknesses of the individual conductors. Crossbars and vias allow the different plating layers to be connected together. This construction allows the individual conductors to be relatively thin and flexible for good electrical and mechanical performance, while creating relatively thick flying leads that are resistant to handling damage.

摘要： An electrical interconnect and a method of making an electrical interconnect in which a conductor has been substantially plated with a first protective metal shell, such as nickel, and a second outer metal shell, such as gold, before a covercoat has been applied. Such an electrical interconnect can be characterized as having an even-thickness outer shell on both its terminal pads and underneath the covercoat adjacent to the terminal pads, without overhangs or gaps near the bottom of the covercoat caused by surface etching during production.

摘要： A disk drive suspension interconnect, and method therefor. The interconnect has a metal grounding layer, a metal conductive layer and an insulative layer between the metal grounding layer and the conductive metal layer. A circuit component such as a slider is electrically connected to the conductive layer along a grounding path from the circuit component and the conductive layer to the metal grounding layer through an aperture in the insulative layer. For improved electrical connection a tie layer is provided through the insulative layer onto the grounding layer in bonding relation with the ground layer. A conductor is deposited onto both the conductive metal layer and the tie layer in conductive metal layer and tie layer bonding relation, and the circuit component is thus bonded to the grounding layer by the conductor.

摘要： A plunger, a needle assembly and a retractable syringe comprising same are provided. The plunger comprises a plunger member and a plunger outer having a lock spring that prevents or impedes movement of the plunger member after needle retraction. The plunger further comprises another locking member for engaging the barrel to prevent or impede further movement of the plunger outer after delivery of fluid contents. The plunger member has a plunger seal which engages a retractable needle of the needle assembly for retraction. The retractable needle comprises a cannula and needle body with a plurality of fluid channels that co-operate with a fluid conduit of the plunger seal to efficiently direct fluid to the cannula. A needle retainer comprises a plurality of barbed arms releasably coupled to the needle body, whereby an ejector with tabs facilitates release of the retractable needle from the needle retainer to allow compressed spring-driven retraction.

摘要： A replaceable needle assembly is provided for a retractable syringe comprising a barrel and a plunger, whereby the retractable needle can be replaced by a user without affecting the retraction mechanism. A mounting member is removably mountable to the barrel by way of a screw-thread connection and a needle mount is removably coupled to the mounting member. A needle is mounted to the needle mount. The barrel comprises a needle mount retainer that comprises a plurality of fingers that engage the retractable needle mount to prevent inadvertent retraction. The plunger comprises a collapsible seal which maximizes the efficiency of fluid delivery prior to the plunger engaging the retractable needle mount for retraction. An initially compressed spring decompresses to drive retraction of the plunger and the engaged needle mount. A lock formed between the plunger and barrel prevents further use of the plunger after retraction.

摘要： Some embodiments provide a system for managing violations during physical verification. The system may identify a design-rule-check (DRC) violation by applying a set of DRC rules to a layout. The system can then receive an error classification from the user which specifies how the DRC violation is to be handled. Next, the system can store the DRC violation, the user-selected error classification, and a user identifier associated with the user in a database. If the user is not authorized to approve the error classification, the database can indicate that the error classification has not been approved. Later, a user who is authorized to approve the error classification can approve the error classification. The system can determine if a cell is known, and if so, the system can use the violations and error classifications stored in the database to speed up the verification process.
