SwifTest-MAX is an optional module in the SwifTest family that provides basic monitoring and alerts. It is a software-only solution that typically runs on the ATE. The user may define specific conditions to monitor for specific devices and what actions are to be taken when the events occur. The rules are applied on a lot by lot basis. These monitoring rules are stored in the Device Profile and read by SwifTest-MAX at the beginning of each lot.
Actions that can be initiated by these alerts include:
- Send an email message,
- Sending a message to the operator console,
- Create and send a report which could be:
- Lot summary report
- SwifTest traceability report
- Test alert
- Binning alert
- Outlier data file
- Execute a system command, such as "halt the tester."
A variety of monitoring conditions or "events" may be defined by the user. These include:
- Statistical exception event
- H/W or S/W binning event
- Percent failing event
- Lot end event
- Tester idle event
- Outlier count event
- Site-site variance vent
- SPC (WECO) quality trend event
- Sampling event
- Test time event (exceeds minimum of maximum)
SwiftTest-Max is an economical way for product engineers and test engineers to define specific conditions that they want to monitor. It may be deployed on a tester by tester basis. Other than reading the Device Profile at the start of lot, and sending a report at the end of the lot, there is no investment required in a special DBMS. For this reason, SwifTest-MAX is limited to "local monitoring" - meaning conditions that occur within a single lot during production. "Global monitoring" means the ability to comprehend trends across multiple testers and multiple lots, and for this, we recommend TestScape.
