Description
Technical field
The utility model relates to heat sensitive chip resistance test technical field, particularly relates to a kind of heat sensitive chip high-accuracy and constant warm air test machine.
Background technology
Original method of testing heat sensitive chip is immersed on the thin conductive metal sheet in constant temperature oil bath, conductive metal sheet is connected with multimeter one instrument connection, connect another multimeter instrument connection with test pencil, test pencil probes in oil tests the resistance of heat sensitive chip in constant temperature oil bath.After the test of this method, need clean chip with degreaser, process operations is numerous and diverse, is unfavorable for batch testing.
Utility model content
The utility model object is exactly the defect in order to make up prior art, provides a kind of heat sensitive chip high-accuracy and constant warm air test machine.
The utility model is achieved through the following technical solutions:
A kind of heat sensitive chip high-accuracy and constant warm air test machine, include air incubator, oil groove is placed with in air incubator inside, thermostatical oil is placed with in oil groove, thick conductive and heat-conductive plate is also placed with in oil groove, 2/3rds parts that are greater than of described thick conductive and heat-conductive plate sink in thermostatical oil, thick conductive and heat-conductive plate is connected with an instrument connection of multimeter by connecting line, heat sensitive chip to be measured is placed with on thick conductive and heat-conductive plate, another instrument connection of multimeter, by connecting line connecting test test pencil, tests test pencil contact measured heat sensitive chip.
The utility model has the advantages that: one piece of conduction and all good thick conductive and heat-conductive plate major part of thermal conductivity are immersed in thermostatic oil bath or tank by the utility model, make thick conductive and heat-conductive plate substantially identical with the temperature of oil groove, heat sensitive chip to be measured is placed on this block sheet metal, and be placed on a temperature-controlled precision in the air incubator of ± 0.03 DEG C, the measuring tempeature of the heat sensitive chip on conductive and heat-conductive sheet metal can be made to control at about ± 0.01 DEG C, realize testing in the air under heat sensitive chip high-precision temperature, substantially increase testing efficiency, the operation that after deleting constant temperature oil bath test, on chip, fluid cleans, the use having evaded the clean-out system that deoils while avoiding oil to damage is polluted.
