摘要： A method and system for high-speed, precise micromachining an array of devices are disclosed wherein improved process throughput and accuracy, such as resistor trimming accuracy, are provided. The number of resistance measurements are limited by using non-measurement cuts, using non-sequential collinear cutting, using spot fan-out parallel cutting, and using a retrograde scanning technique for faster collinear cuts. Non-sequential cutting is also used to manage thermal effects and calibrated cuts are used for improved accuracy. Test voltage is controlled to avoid resistor damage.

摘要： A calibration method for a potentiometer which provides indicia reflecting an accurate indication of actual electrical resistance throughout the resistive range of a particular potentiometer. The indicia includes a number of graduation marks or symbols having a range and spacing unique to the resistive characteristics of the particular potentiometer. The indicia is fixed with respect to a known location associated with the particular potentiometer. The range and spacing of the indicia graduations is derived from measured resistance values at predetermined locations along the resistive member of the particular potentiometer.

摘要： A method and apparatus provide fuse trimming of analog integrated circuit parameters in plastic packages. The apparatus includes an electrically interruptible circuit element, such as a fuse; a level reading unit which reads the state of the electrically interruptible circuit element and generates a code in response to the state; a state altering unit, such as a current source for providing a blow current; and a control circuit. A test level reading device allows screening for marginally-blown fuses. A switchable element removes applied voltage from fuses when the fuse is not being blown or read to prevent fuse regrowth.

摘要： A thermal print head trimming apparatus trims the resistances of heating resistor elements (4a). The apparatus divides the measured resistance data into plural groups by their variation range, and applies pulse signal of high-voltage by a probe electrode (6) to the heating resistor elements (4a) in the plural groups except a group that includes the lowest resistance values of the heating resistor elements (4a). Thereby the whole resistances of the heating resistor elements (4a) in the thermal print head are trimmed to agree with the lowest resistance values.

摘要： A trimming resistor network includes first and second external connection terminals (T1, T2), a first resistor (11) having two ends acting as first and second connection terminals (11a, 11b), a first coupling body (13) for connecting the first external connection terminal (T1) to the first connection terminal (11a) via series-connected resistors (R2, R4), a second coupling body (14) for connecting the second external connection terminal (T2) to the second connection terminal (11b) directly or via series-connected resistors, and parallel trimming resistors (R3) having two ends respectively connected to the first and second coupling bodies (13 and 14). The combined resistance between the first and second external connection terminals (T1 and T2) is increased by substantially a preset amount each time one of the parallel trimming resistors (R3) is cut off.

摘要： A surge protector, particularly for protecting components in a telecommunications system, has a thin ceramic substrate (20) on a surface of which is formed a surge protector resistor (21,22) having a spiral pattern in the form of a double spiral (23) having two parallel resistor paths in series, the width of the paths and the distance between adjacent path lengths being relatively narrow. Resistance trimming means (26) are provided for increasing the length of a resistor path, there being substantially even distribution of surge effects under surge conditions

摘要： In a process for the production of a rotary electrical potentiometer, a spindle means is provided initially in the form of a first part (10), which is adapted to be rotated by means external to a housing (1A, 1B), and a second part (11) to which is secured a wiper (15) which traverses a resistance track (2). The first and second parts (10, 11) of the spindle are mutually engageable such that one part is rotatable about the other. Relative rotation is effected between the parts (10, 11) such that with the first part (10) in a predetermined position of rotation relative to the housing (1A, 1B), the wiper (15) secured to the second part is arranged to be in a required position with respect to the resistance track (2). The two parts (10, 11), which suitably comprise a thermoplastics material are then secured together against further mutual rotation, e.g. using ultrasonic welding or heat sealing techniques.
