Welcome back to “A Minute with Miranda.” This week we will be covering how the Ground Master Monitor provides continuous monitoring of the path-to-ground impedance and electromagnetic integrity of eight metal ground connections of process tools in your SMT assembly work area.
The Ground Master Monitor
continuously monitors eight metal tools for electromagnetic interference (EMI).
EMI can cause equipment lockups and malfunction. The Ground Master Monitor will
alarm if EMI is detected. The Ground Master will also alarm if the grounded
metal tools have a high-frequency noise that can cause electrical overstress
(EOS) damage. The Ground Master Monitor provides both a visual and audible
alarm for the monitored ground connections. The Ground Master Monitor meets the
Continuous Monitor requirements of ANSI/ESD S20.20 in accordance with ESD TR53.
Sensitivity to electrostatic discharge (ESD) is an important concern in PCB assembly manufacturing. Pinpointing where ESD events are occurring on an SMT line can be difficult determine. ESD exposure can take place anywhere in the process, including PCB loading, component handling, soldering, and operator interventions. ESD events generate electromagnetic radiation. The stronger the ESD event, the stronger the electromagnetic radiation. Detecting and measuring the unique waveform generated by an ESD event can help determine where the ESD event is occurring and reduce the time it takes to identify and solve the problem. Watch this video to see how continuous ESD Event Detection monitoring can be setup on an SMT Line to monitor the processes and triangulate where static voltage and ESD events are occurring in the process.
Welcome back to “A Minute with Miranda.” This week we will be covering how the EM Aware Monitor provides continuous monitoring to detect and measure ESD Events in your STM machine.
The SCS EM Aware Monitor is a continuous monitor for three key parameters that allow you to verify your ESD process in an automated insertion machine; ESD events, change in static voltage field, and ionizer balance. The thresholds for all three of these parameters are fully adjustable by the user. The EM Aware Monitor is a miniature radio receiver tuned to detect and measure the unique waveform generated by an ESD event. The EM Aware Monitor meets the Continuous Monitor requirements of ANSI/ESD S20.20 in accordance with ESD TR1.0-01 and ANSI/ESD STM3.1. It meets the recommendations of ESD Handbook ESD TR20.20 which includes “if the products that are being produced are of such value that the knowledge of a continuous, reliable ground is needed, then continuous monitoring should be considered or even required.”
Welcome back to “A Minute with Miranda.” This week we will be covering how the WS Aware provides continuous monitoring for an operator at an SMT line.
The SCS WS Aware Monitor is a continuous monitor for operators, ESD Worksurfaces and metal tools. It will continuously monitor the path-to-ground integrity and body voltage of two operators. It also monitors the path-to-ground integrity of two metal tools. In addition, it continuously monitors for electromagnetic interference (EMI) on two metal tools, which may cause electrical overstress (EOS) damage. The WS Aware Monitor eliminates the need for periodic testing and record keeping of wrist straps.
Per ESD Handbook ESD TR 20.20 section 22.214.171.124.4 “Typical Test programs recommend that wrist straps that are used daily should be tested daily. However, if the products that are being produced are of such value that knowledge of a continuous, reliable ground is needed, then continuous monitoring should be considered or even required.”
