摘要:
A disc drive apparatus (1) comprises; a) actuator means (50) for controlling the positioning of an element (34) of a scanning means; b) error signal calculating means (111, 112) for receiving a read signal (SR) and generating at least one error (RES; e(k)); c) a state estimator (120) for receiving said error and for outputting derived signals (s1, s2, s3); d) shock detector means (130) for generating a shock indication signal (SIS) on the basis of one (s1) of said derived signals; e) actuator control signal generator means (190) having at least one variable control parameter, for generating an actuator control signal (RAD; u(k)) on the basis of a second one (s2) of said derived signals; f) the actuator control signal generator means setting a first value for said variable control parameter during normal operation, and setting a second value for said variable control parameter when said shock indication signal indicates the occurrence of a shock.
摘要:
A contact structure for establishing electrical connection with contact targets. The contact structure is formed of a contactor carrier and a plurality of contactors attached to a contactor carrier. The contactors are inserted in diagonal through holes on the contactor carrier and attached to the contactor carrier through adhesives. The contactor has a top end having a flat top surface, a straight diagonal beam integral with the top end and configured by an upper beam portion and a lower beam portion, and a lower end at an end of the lower beam portion to contact with a contact target. A length of the upper beam portion and a length of the lower beam portion are about the same. A probe contact assembly using the contact structure is also disclosed which incorporates a flip chip bonding technology to interconnect the components therein.
摘要:
A probe contact system is capable of adjusting distances between tips of the contactors and contact targets with simple and low cost mechanism. The probe contact system includes a contact substrate having a large number of contactors, a probe card for fixedly mounting the contact substrate for establishing electrical communication between the contactors and a test system, a stiffener made of rigid material for fixedly mounting and reinforcing the probe card, a probe card ring attached to a frame of the probe contact system for mechanically coupling the probe card to the frame, and a plurality of adjustment members for up/down moving the stiffener relative to the probe card ring at three or more locations so that a gap between the probe card and the probe card ring can be altered.
摘要:
A method for producing a contact structure for establishing electrical connection with contact targets. The contact structure is formed of a contact substrate and a plurality of contactors. The contactor has a tip portion at one end of the contactor to contact with the contact target, a base portion at another end of the contactor which is inserted in a through hole provided on the contact substrate in such a way that an end of the contactor functions as a contact pad for electrical connection at a surface of the contact substrate, and a spring portion provided between the tip portion and the base portion which produces a contact force when the contactor is pressed against the contact target.

A contact structure for establishing electrical connection with contact targets. The contact structure is formed of a contact substrate and a plurality of contactors. The contactor has a contact portion which is oriented in a vertical direction to form a contact point, an intermediate portion which is inserted in a through hole provided on the contact substrate, and a base portion having a base end which functions as a contact pad and a spring portion provided between the base end and the intermediate portion for producing a resilient contact force when the contactor is pressed against the contact target.
摘要:
A contact structure is formed of a contact substrate and a plurality of contractors. The contactor is uniformly formed of conductive material and has an intermediate portion which is inserted in the through hole provided on the contact substrate in a vertical direction, a contact portion which is connected to the intermediate portion and positioned at one end of the contactor to function as a contact point for electrical connection with a contact target, and a base portion which is provided at other end of the contactor, and a spring portion which is substantially straight and upwardly inclined relative to the surface of the surface of the contact substrate and provided between the base portion and the intermediate portion. The intermediate portion is staright and a portion of which is reduced in width or thickness.
