Abstract
Apparatus including a planar support having a plurality of terminations such as plated through holes arranged therein in an array and a plurality of sensing devices respectively associated with the terminations for measuring a physical quantity thereat such as temperature. The resulting structure is useful for training a person in a manual skill such as soldering. Also disclosed is a common connector plug for receiving at one side of the support a plurality of electrical leads from the sensing devices and an analyzer and indicator connected to the common plug for measuring the time required for the temperature and/or pressure at one of the terminals to rise from an initial value to a final value, the terminal being that to which a device such as a soldering iron is applied to effect the soldering of an electrical connection thereat. If the trainee successfully raises the temperature from the initial to final value within a desired period of time, an indication is made of this fact to provide positive reinforcement for the trainee.
