The patent relates to a method and apparatus for controlling the fabrication of electroexplosive devices. An electroexplosive device is loaded with an explosive by pressure loading or ignition drop or other techniques, the explosive surrounding and electroexplosive bridge-wire located within the device. A self-balancing bridge is connected to the bridgewire to monitor the bridgewire thermal conductance during loading. In one embodiment of the invention, an indicator is connected to the self-balancing bridge to display the variation in thermal conductance providing an indication of the thermal contact between the explosive and the bridgewire. In an alternative embodiment, the output of the self-balancing bridge is coupled to a comparator which compares the bridgewire thermal conductance to a desired value.
