A method and apparatus for testing circuit boards using two or a small number of probes for making resistive and radio frequency impedance measurements e.g. capacitive measurements. The combination of resistive and impedance measurements substantially reduces the number of tests required to verify the integrity of a circuit board. The impedance or capacitive 'norm' values used in testing the circuit boards can be obtained by operating the system in a learning mode. Analysis of the data provides not only fault detection but also can indicate approximate fault location.

Method and apparatus for testing of electrical interconnection networks

A process for extending and fixing conductors to circuit board base surfaces between pre-established spaced points in straight paths and pre-established spaced points in inflected paths, the steps comprising, fixing the end of the conductor to a pad at the first of a pair of pre-selected points and, while feeding the conductor with a guide, moving the board and the guide relative to each other along a straight path to a pad at the second of the pair of pre-established points or to a pad at an inflection point, if the conductor is to be inflected, and then to said second pad. Severing said conductor at said second pad and affixing the conductor end to said second pad. Repeating the foregoing steps until the conductor has been affixed to the pre-established pairs of pads and to the pads at the inflection points. After all of the pre-established spaced points have been interconnected with conductors either in straight or inflected paths, affixing the conductors to the board blank surface with a adhesive by applying pressure to the conductor pattern.

Process for the manufacture of circuit boards

A multi-wire electrical interconnecting circuit member having a multi-wire matrix of insulated wires mechanically terminated on the multi-wire electrical interconnecting member. Wire retaining members positioned on the multi-wire electrical interconnecting member terminate the wires and establish a gas-tight electrical connection therewith. Each of the wire retaining members includes means for engaging a wire with sufficient force to penetrate any insulation thereon and establish and maintain a gas-tight electrical connection with the conductive core of the wire.

Multi-wire electrical interconnecting member having a multi-wire matrix

This invention generally relates to prefabricated electric wire assemblies comprising an interconnected network of separately formed, integral, shaped conductors, and to materials and techniques used in the manufacture of such assemblies.

Method of making multi-wire electrical interconnecting member having a

A self-commutating motor including main magnets to provide a magnetic field and a rotatable printed circuit armature positioned therebetween. The armature rotates in a self-commutating fashion with a pair of centrally mounted brushes. The printed circuit armature includes two insulating layers having printed circuit conductive elements thereon, and a low reluctance laminated core to which the layers are bonded. The conductive elements may be skewed to a maximum of about 3.degree. and the conductive elements of each layer are electrically interconnected so that the forces on the conductive elements, resulting from interaction of the current flowing in the conductors with the magnetic field, cooperate to apply a torque to the armature of the motor.

Self-commutating motor and printed circuit armature therefor

Apparatus for advancing magnetic tape with respect to a recording head through small, discrete, and uniform displacement increments. A direct current drive motor has an armature shaft that drives a displaceable member. Controls develop signals that energize and deenergize the motor. Included in these controls are a speed responsive tachometer and an acceleration control utilizing a saturable amplifier.
