Note: STS strongly recommends using the JEDEC Std. for testing. It is a more current specification than the Mil Std. and is the standard the industry is moving towards.
Please list the Power pins or pin-groups to be tied separately, including ground groups. Also, indicate the number of pins in each group. (Use end of Request to list additional Pin-groups)
Note: Multiple Vdd(Power) bus dramatically increases the test time and the number of times each pin will be zapped. It also increases the cost and cycle time. We normally connect all Vdd (Power) pins that are on the same plane (type/value) on one bus, unless specified otherwise. It is also recommended that analog and digital power pins be separated even though they are fed from the same supply.
Note: Multiple Zapping can result in cumulative damage to the device. STS, therefore, recommends that devices be zapped at a single voltage for qualification purposes.
Note: Our System has the capability to specify which polarity to Zap first. Please indicate by Yes or No if you have preference.
Note: If curve tracing is required it should only be used as an indication that the pin I/V characteristics have changed. Curve tracing should NEVER be used in defining pass/fail criteria for qualification of a device. Both Mil Std. and JEDEC specify that only electrical test be used to determine whether the device has passed ESD testing or not.
