It employs severe conditions of temperature, humidity, and bias which accelerate the penetration of moisture through the external protective material encapsulant or seal or along the interface between the external protective material and the metallic conductors which pass through it.

Calibration records shall verify that, for steady state conditions and maximum thermal mass loading, test conditions are maintained within the tolerances specified in Temperature profile A permanent record of the temperature profile for each test cycle is recommended, so that the validity of the stress can be verified. Devices under stress shall be no closer than 3 cm from internal chamber surfaces, and must not be subjected to direct radiant heat from heaters.

X110 on which devices are mounted should be oriented to minimize interference with vapor circulation. For parts that require more than 24 hours to jeed22 equilibrium at the specified HAST condition, the time should be extended to allow parts to reach equilibrium. For plastic-encapsulated microcircuits, it is known that moisture reduces the effective glass transition temperature of the molding compound.

NOTE The priority of the above guidelines depends on mechanism and specific device characteristics. If the heat dissipation of the DUT exceeds mw, then the die temperature should be calculated. Heating as a result of power dissipation tends to drive moisture away from the die and thereby hinders moisture-related failure mechanisms. Cycled bias permits moisture collection on the die during the off periods when device power dissipation does not occur.

Exposure of devices to excessively hot, dry ambient or conditions that result in condensation on devices and a1110 fixtures shall be avoided, particularly during ramp-up and ramp-down. Condensation shall be avoided by ensuring that the test chamber dry bulb temperature exceeds the wetbulb temperature at all times, and that the rate of ramp up shall not be faster than a rate which ensures that the temperature of any DUT does not lag below the wet bulb temperature.

In a dry laboratory, the chamber ambient may initially be drier than this. There is no time restriction, and forced cooling of the vessel is permitted. Condensation on devices shall be avoided in both parts of the ramp down jesdd22 ensuring that the test chamber dry bulb temperature exceeds the wet-bulb temperature at all times. Ramp-down should maintain the moisture content of the molding compound encapsulating the die.

Bias should be verified after devices are loaded, prior to the start of the test clock. Bias should also be verified after the test clock stops, but before devices are removed from the chamber. For intermediate readouts, devices shall be returned to stress within 96 hours of the end of ramp down.

The rate of moisture loss from devices after removal from the chamber can be reduced by a1100 the devices in sealed moisture barrier bags without desiccant.

Thus the test window can be extended to as much as hours, and the time to return to stress to as much as hours by enclosing the devices in moisture-proof bags. Contamination control is important in any highly-accelerated moisture stress test. The following document contains information on Cypress products. Handling Precautions Any semiconductor devices have inherently a certain rate of failure. The possibility of failure. The leads should be bent by clinching the upper part of the lead firmly such that the bending.
