Method for an unshielded magnetic loop-type antenna for embedding into a machine as a default real-time ESD monitor tool

Disclosed is a method for an unshielded magnetic loop-type antenna for embedding into a machine as a default real-time electrostatic discharge (ESD) monitor tool. Benefits include improved functionality and an improved manufacturing environment.

Background

         Conventional ESD monitor tools are offline or semi-real-time measurement functions that either stop the machine or are a removable device (see Figure 1).

         Unshielded magnetic loop-type antennas detect a real-time electromagnetic interference (EMI) spectrum for mapping out an ESD event. This antenna requires a separate high-frequency oscilloscope and ESD experts to interpret the spectrum results. These antennas take a long time to install and calibrate. As a result, this solution is not a practical measurement during manufacturing. A machine-default function is required.

Description

The disclosed method embeds a network of unshielded magnetic loop antennas and triggering software to monitor real-time ESD events as a machine-default function. A 2-GHz (or higher) oscilloscope is required as a part of the machine. The real-time measurement and alert function should be programmed into the specialized software (see Figure 2).

         With the disclosed method, manufacturing people can monitor ESD events as they occur. Notification is received through specialized software. Immediate action can be taken to prevent ESD ex...
