What do you need to know about ESD testing?
ESD tests are performed either for design validation or product certification. During ESD testing, Equipment Under Test (EUT) is tested with the items shown below Each item is chosen according to standard applied. ESD test setups are prepared according to applied standard.
When to eat or drink before an ESD procedure?
Many referring physicians may not even know about this option. For a lower GI tract procedure, follow a liquid diet plus a laxative or enema to cleanse the bowel. For an upper GI tract procedure, do not eat or drink for 12 hours before the procedure to ensure your esophagus is clear of food.
How are the signals generated in an ESD gun?
When you prepare the test setup (making necessary connections of ESD generator, test table, ground planes, grounding) ESD test expert (technician or engineer) applies the ESD signals to the EUT and checks the performance of it. Each ESD signal is generated by ESD simulator or gun is counted and recorded for reporting.
What kind of endoscope is used for ESD?
Gastroenterologists (doctors specially trained to treat the GI tract) use flexible, tube-like imaging tools called endoscopes to perform ESD. Most people go home the same day. Only a few centers in the United States perform ESD because the procedure requires a high degree of expertise with the procedure.
Which is ESD test simulates real world events?
Of all of the component-level ESD tests available, the charged-device model (CDM) test is the closest to simulating real world events. CDM testing simulates ESD charging followed by a rapid discharge, similar to what is seen in the automated handling, manufacturing, and assembly of IC devices.
What do you need to know about electrostatic discharge?
This section describes the ESD (Electrostatic Discharge) standards and ESD testing. Manufacturers of electronic devices are required to devise appropriate ESD countermeasures that satisfy the standards of each electronic device, and various tests and standards have been enacted for each purpose and product.
What is the IEC 61000-4-2 standard for ESD?
Since IEC 61000-4-2 is a test standard and not a product standard, you have to check ESD test levels from applicable product standard. For instance, for medical devices, IEC/EN 60601-1-2 standard defines test levels as -/+2kV, -/+4kV and -/+8kV for air discharges and -/+2kV, -/+4kV and -/+6kV for contact discharges.
