ESD for Warehouse Process Training Acceptance Tolerance Table Purpose: Outline of ESD Acceptance Ranges H Step Action 1 High Level Outline Of Resistance and Static Voltage Charge for Items in an ESD Work Area 2 All Items – items that enter the ESD work area shall be tested to verify resistance value and static charge properties to understand and identify if they should be in the ESD work area and proper handling of that item be identified. It is recommended that only items that are absolutely needed be in the ESD work area 3 Footwear – between ≥1x105 to ≤1x109 ohms 4 Work Surface - ≥1x105 to ≤1x109 ohms surface to surface and surface to ground 5 Dissipative Chair - <1x109 ohms from seat back to known building ground 6 Racks and Cabinets - <1x109 ohm, conductive also allowed 7 Wrist Straps & Groundable Smocks – Wrist Straps – ≥5x105 to <5x109 & Groundable Smocks ≥1x105 to <1x109 8 ESD Table Mats - ≥1x105 to <1x109 ohms surface to surface and surface to ground 9 Dissipative Flooring - ≥1x104 to <1x109 ohms tile to tile and tile to ground (target is 1x107 ohms using 5 lb weights) 10 Relative Humidity - > 40% (Dew Point 50° ±3°) 11 Temperature - 12 Work Surface Storage Bins – 13 Adhesive Tape - shall not generate greater than (+/-) 200V/in when pulled from roll as measured with an electrostatic field meter 14 Vacuum Wand - for contact to non-conductive parts of device (IHS, substrate, underfill, etc.) resistance <1x109 ohms; for contact to conductive parts (land, pin, ball, etc.) resistance of ≥1x104 to <1x1011 ohms 15 Ionizers – if used Rev. 1.0 70 deg F (+/-) 5 deg F or 21 deg C (+/-) 3 deg C surface resistance of between - ≥1x105 to <1x109 and shall not induce an electrostatic field greater than ± 200V/in measured at the location of device shall be capable of dissipating charge of +/-1000v to +/-100v in less than 10 sec.
