|
|
|
| |
|
myCIM is a comprehensive CIM solution
for wafer fabrication and IC assembly and test. This product
is more than a MES system as it encompasses the full functionality
of Manufacturing execution, automation and production data mart.
It helps the customer to reduce miss processing trough detail
control for each processing step, Improve machine utilization
through resource tracking and preventive maintenance, improve
Yield through data collection and apply statistical process
rules for the data collection. Data can be collected manually
or through automation. It provide visibility to the shop floor
through Product data Mart. |

All the shop floor activities can be
controlled and full traceability and genealogy is provide for
each lot execution in the shop floor. Traditional MES can only
track by lot, myCIM allows tracking of work in process by unit
or die. Binning and grading is alos provided. Dispatch rule
can also be defined for each operation. Lot is automatically
priority according to dispatch rule.
