EXPERT WITNESS ETS provides expert witness services in the area of electrostatics. These include, test and evaluation of the electrostatic characteristics of materials, products, personnel safety and ESD sensitive environments. Support is given to the legal staff in the form of test data, formal reports, depositions and testimony in court. ^ Top OVERVIEW Consulting, Training And Expert Witness Projects The following information reviews consulting, auditing and training projects ETS has been retained to perform. All projects are tailored to meet the specific needs of the client. Due to confidentiality arrangements, company names cannot be disclosed. ^ Top MANUFACTURING ISSUE: A new generation of electronic devices were found to be susceptible to ESD voltage levels of less than 30 volts and units were randomly failing. SOLUTION: A site survey was performed which determined the ionization equipment that was installed was actually charging the parts and personnel. ETS trained the clients in how to implement corrective action and maintain a static free work area. ISSUE: A company purchased a new division with the intent of expanding into the ESD Industry, however, they possessed little expertise in electrostatics. SOLUTION: ETS was retained to present a training seminar on Electrostatics which was filmed and shown to additional employees. ISSUE: Lack of awareness of the effects of static electricity were contributing to product failure and low yields due to particulate contamination, misuse of ionization equipment and lack of awareness. SOLUTION: An ESD training session was scheduled to educate staff and a facility audit was performed to locate problem areas. Recommendation were made to implement static-safe procedures and train staff. ESD equipment recommendations were made. ISSUE: The particulate flow rate of multiple nozzles was being reduced due to clogging. This in turn was causing defective products to be produced. SOLUTION: Electrostatic charge levels were used to monitor the particulate flow. When a line clogged, an alarm signal generated a warning and stopped the process. Equipment was designed and installed by ETS and training was provided. ISSUE: Stacking operation for cardboard containers used for liquid (juice, milk, etc.). Static was causing problems with stacking the boxes as they were being manufactured. High static charge levels were being generated during handling and stacking. SOLUTION: ETS conducted a facility audit and process analysis to determine where static was being generated. ETS then recommended systems which could be used to reduce static build-up. ISSUE: A packaging manufacturer wanted to educate their customers on the proper use of electrostatic packaging materials. SOLUTION: ETS was retained to provide a tutorial. The manufacturer invited key customers to a two-day seminar where training was provided on understanding terminology and proper use of materials. ^ Top EXTRUSION OF FILMS, POLYMERS & COATING ISSUE: Static discharges were causing streaks on film. SOLUTION: After performing a survey and evaluating the process, ETS recommended modifications to the film developing machine to eliminate static related problems. ISSUE: Light streaks caused by ESD were ruining film. SOLUTION: The operation was audited and equipment was installed to correct the problem. Training was also provided. ISSUE: The coating supply would periodically run dry causing the base film to generate sufficient static charge levels to ignite solvents. SOLUTION: ETS designed a monitoring system to warn and then shut down the process when minimum static levels were exceeded. ISSUE: An extruded product running at very high speeds was breaking when the machine speed reached a certain point resulting in a loss of time and money. Triboelectric charge generation was suspected. SOLUTION: ETS conducted a facility audit and performed measurements during operation. ETS determined that static was being generated and could be quantified. A report was generated and equipment was recommended and purchased to eliminate the problem. ISSUE: A flash fire caused an extrusion and coating line to be shut down indefinitely pending the determination of the source of the fire. An ESD event was suspected. SOLUTION: An ESD Consultant was rushed to the facility to interview staff on the actions leading up to the fire and to also monitor the process which was run under controlled conditions. Observations and drawings were supplied in the form of a report. Recommendations were offered on how to eliminate potential problems and equipment was supplied. ^ Top AVIATION AND AEROSPACE ISSUE: Buildup of static electricity on propeller blades. SOLUTION: Materials were tested at both ETS and the customer's facility. Industry specifications were reviewed and a report with recommendations was generated. ISSUE: Out of date specification and procedures. SOLUTION: ETS was issued a contract to review existing specifications and develop new methods to improve measurement reliability. ISSUE: Communications equipment failing due to low level ESD events. SOLUTION: A site survey was performed to locate the source of the problem and recommendations were made to eliminate the problem. ^ Top BIOMEDICAL & PHARMACEUTICAL ISSUE: Static electricity was causing production problems during the automatic insertion of pills into the plastic package. SOLUTION: The process was evaluated during a site survey. Recommendations were made and training of personnel was performed to eliminate the problem. ISSUE: The failure (in a hospital) of patient care electronic equipment SOLUTION: A site survey was performed and recommendations were made to the hospital and equipment manufacturer. ^ Top AUTOMOTIVE ISSUE: Safe handling of airbag and pretentioner initiators. Airbag and seatbelt pretentioners are designed to be immune from ESD events up to 25kV. Under certain circumstances, the complete system can be susceptible to ESD events at less than 5kV. SOLUTION: ETS conducted facility audits at multiple locations and also conducted ESD susceptibility testing of devices and systems. ETS recommended static control procedures to be instituted to ensure safe handling of the product. ISSUE: A manufacturing company wanted to evaluate their in-house ESD program. SOLUTION: The company retained ETS to perform a facility audit on the current level of static awareness. A report was prepared based on the findings and recommendations were made on static control procedures to be instituted to ensure safer handling of the product and increased productivity. ETS was subsequently retained to perform ESD Audits at other divisions. ^ Top OTHER ISSUE: Static Dissipative flooring was installed in communications facility and needed to be verified. SOLUTION: ETS was retained to perform an audit confirm that the material was within acceptable limits. A report was generated with the findings. ISSUE: Nonwovens - Static charges were affecting the performance of high-speed machinery causing jams to occur. SOLUTION: ETS performed a site survey and recommended the correct static control procedures, installation of equipment to monitor and eliminate problems and training of personnel. ISSUE: Oil - Establishing safe ESD levels for wipe materials used to clean oil and other spills. SOLUTION: Materials were evaluated and a specification was written by ETS for the industry to use as a guideline. ISSUE: FIBC'S (Flexible Intermediate Bulk Containers) - No industry guidelines were in place for the proper testing of FIBC's. SOLUTION: Materials were evaluated by ETS and guidelines were recommended. ISSUE: Canned Cooking Fuel – Evaluate plastic shipping containers and fuel for the effects of ESD and determined the ignition energy level. SOLUTION: Packaging and material was evaluated and ignition energy thresholds were established. ^ Top EXPERT WITNESS ISSUE: A lawsuit was filed on patent infringement. ACTION: ETS was retained to perform ESD Material Testing, provide support for law staff on ESD issues and terminology and then to provide testimony in court as an expert witness on ESD issues. ISSUE: Static discharge was suspected in a personal injury suit. ACTION: ETS was retained to evaluate the electrostatic characteristics of the product and provide a formal report. The test data and reports were used as evidence. ^ Top PROFESSIONAL BACKGROUND STANLEY J. WEITZ - PRESIDENT, ELECTRO-TECH SYSTEMS, INC.
