Abstract

There are disclosed systems, computer program products, and method for monitoring electrostatic discharge (ESD) fault conditions and controlling manufacturing processes on an assembly line. In an embodiment, each ESD monitored station in an assembly line is provided with at least one ESD management device (e.g. an ESD monitoring device or ESD protection device). Predetermined ESD fault conditions may be used to automatically stop a manufacturing process at an ESD monitored station. Upon occurrence of an ESD fault condition an ESD fault notification message may be sent identifying the ESD monitored station, the nature of the ESD fault condition, and whether the manufacturing process at the ESD monitored station is stopped. The ESD fault notification message may be sent to a mobile communications device, for example, and the manufacturing process at the ESD monitored device may be controlled based on a reply received from the mobile communications device.

Claims

1. A method of monitoring electrostatic discharge (ESD) fault conditions and controlling a manufacturing process on an assembly line, comprising:

providing at each ESD monitored station in the assembly line at least one ESD management device;

monitoring each ESD management device for an occurrence of at least one ESD fault condition;

upon occurrence of at least one ESD fault condition at an ESD monitored station, determining based on predetermined criteria whether the manufacturing process at the ESD monitored station should be stopped;

sending a notification of the at least one ESD fault condition to a mobile communication device, the notification indicating whether the manufacturing process at the ESD monitored station is stopped; and

providing in the notification a control action that may be taken by reply to the notification.

2. The method of claim 1, further comprising controlling the manufacturing process at the ESD monitored station based on the reply to the notification.

3. The method of claim 1, wherein the notification is an email message, and the method further comprises controlling the manufacturing process at the ESD monitored station based on a reply to the email message.

4. The method of claim 1, wherein the notification is an input to an application running on the mobile communications device, and the method further comprises controlling the manufacturing process at the ESD monitored station based on a control action reply output from the application.

5. The method of claim 1, further comprising identifying in the notification the ESD monitored station and the nature of the ESD fault condition.

6. The method of claim 5, further comprising controlling the manufacturing process at the ESD monitored station in response to a control action reply from a webpage accessible via a web browser application provided on the mobile communications device.

7. A system for monitoring electrostatic discharge (ESD) fault conditions and controlling a manufacturing process on an assembly line, the system comprising computing means and storing means adapted to:

provide at each ESD monitored station in the assembly line at least one ESD management device;

monitor each ESD management device for an occurrence of at least one ESD fault condition;

upon occurrence of at least one ESD fault condition at an ESD monitored station, determine based on predetermined criteria whether the manufacturing process at the ESD monitored station should be stopped;

send a notification of the at least one ESD fault condition to a mobile communication device, the notification indicating whether the manufacturing process at the ESD monitored station is stopped; and

provide in the notification a control action that may be taken by reply to the notification.

8. The system of claim 7, wherein the system is further adapted to control the manufacturing process at the ESD monitored station based on the reply to the notification.

9. The system of claim 7, wherein the notification is an email message, and the system is further adapted to control the manufacturing process at the ESD monitored station based on a reply to the email message.

10. The system of claim 7, wherein the notification is an input to an application running on the mobile communications device, and the system is further adapted to control the manufacturing process at the ESD monitored station based on a control action reply output from the application.

11. The system of claim 7, wherein the system is further adapted to identify in the notification the ESD monitored station and the nature of the ESD fault condition.

12. The system of claim 11, wherein the system is further adapted to control the manufacturing process at the ESD monitored station in response to a control action reply from a webpage accessible via a web browser application provided on the mobile communications device.

13. A computer program product comprising a computer readable medium storing computer code that when loaded into a computing device adapts the device to monitoring electrostatic discharge (ESD) fault conditions and control a manufacturing process on an assembly line, the computer readable medium including:

code for monitoring each ESD management device at an ESD monitored station in the assembly line for an occurrence of at least one ESD fault condition;

code for determining based on predetermined criteria whether the manufacturing process at the ESD monitored station should be stopped upon occurrence of at least one ESD fault condition at an ESD monitored station;

code for sending a notification of the at least one ESD fault condition to a mobile communication device, the notification indicating whether the manufacturing process at the ESD monitored station is stopped; and

code for providing in the notification a control action that may be taken by reply to the notification.

14. The computer program product of claim 13, wherein the computer readable medium further includes code for controlling the manufacturing process at the ESD monitored station based on the reply to the notification.

15. The computer program product of claim 13, wherein the computer readable medium further includes code for identifying in the notification the ESD monitored station and the nature of the ESD fault condition.
