CL Tweezers ESD Testing



QUALITY ASSURANCE ESD TESTING PROCEDURES FOR "CL" COPOLYMER TIP TWEEZERS
"The Technical Source!"


TDI/Ideal-Tek meets all of the criteria for ESD Testing, as proposed by IDEMA. All of these testing procedures are performed internally. Back to CL Tweezers Page


POINT-TO-POINT RESISTANCE


Resistance Between Tip Top and Bottom (Tip Without Handle) Resistance Between Handle and One Tip at A Time Surface Resistance 100% Inspection Automatic PASS/FAIL Signal The acceptance limits have been defined as follow: Low Resistance Limit: 1.10⁰⁴ Ohm/high resistance limit: 1.10⁰⁶ Ohm for 50 and 100V

STATIC DECAY ANALYSIS
The time to discharge a 20pf isolated metal plate previously charged to 1000 Volts to less than 10 Volts is measured. During the 1000 Volt discharge, sparks should not be observed. The decay curves should have a correct exponential course. The acceptance limits defined as follows: Residual Voltage < 3 Volt Decay Time < 500 m/second

TRIBOELECTRIC CHARGE DETERMINATION

The purpose of this discharge test is to measure any residual charges on the tweezers following normal grounding procedures as shown. The acceptance limits defined as follows: Residual Voltage < 3 Volt
