To obtain technical information and guidance on ESD control, there are a number of sources, many available at no charge. The ESD Association sells most of their documents, but a number are available as complimentary downloads. Per ANSI/ESD S20.20, Compliance Verification of ESD Protected Area’s (EPA) ESD control items is to be per ESD TR53;…
We see many companies with a conductive tile floors that measures mid-10^5 ohm resistance to ground and the operators are wearing foot grounders on each foot that passes the touch-testing, but what peak voltage on the body is generated? Over the years, there have been independent studies conducted per ANSI/ESD STM97.2, Floor Materials and Footwear…
In The People section of the galleries, Desco’s Reztore™ Surface and Mat Cleaner is shown in use on the cart of an operator that is diagnosing one of the servers. From the EE Times Article Titled “Google opens doors to its data centers — sort of” Google posted a blog pointing to an extensive photo gallery of the…
HUMAN BODY MODEL The updated standard ANSI/ESDA/JEDEC JS-001-2011, For Electrostatic Discharge Sensitivity Testing Human Body Model (HBM) – Component Level Table 3 has divided the Class 0 classification into two withstand voltage levels with class 0A being less than 125 volt sensitivity, and class 0B being 125 to less than 250 volts. If handling class…
Trustat™ NEW B80 mats are .080″ thick, extruded homogenous vinyl material. It is designed to provide a path to ground and eliminate static charge generation when used as a worksurface table mat, shelf liner, or tray liner. The surface resistance (1 x 10E6 < 1 x 10E9 ohms Rtt) meets the ANSI/ESD S20.20 worksurface required…
Desco moved in a new screw machine last week to our Chino, CA manufacturing location. The new-to-us Brown & Sharpe Ultramatic R/S will take the place of the previous machine that we had been using since the early 1970’s. Yes, we have been making things for that long. The new machine is tight, smooth, and very quiet. It will be used to make proprietary parts used in products such as Desco wrist straps, Menda stainless steel probes and EMIT testers. Desco Industries, Inc. manufactures ESD control products and other production supply products at two UK and six USA factories.
REStronics New England is hosting their Annual Seminar Event on: Tuesday, September 18, 2012. 8 AM – 5 PM in Boxborough, MA. The event will feature educational and informative seminars conducted throughout the day. Ted Dangelmayer; BSEE and President of the New England ESD Association Chapter will be presenting the following seminars on ESD control topics: – Realistic ESD…
Activates when operator is at workstation
Deactivates when workstation is vacant to:
Conserve Energy
Reduce Ionizer Maintenance
The Desco ionizer motion sensor is designed to automatically activate an ionizer when an operator is present at the workstation and to turn off when the workstation is vacant. Automatically activating the ionizer ensures that the ionizer is used at workstations where required and deactivating the ionizer when the workstation is vacant will conserve energy and increase the maintenance intervals of the ionizer. The control unit is capable of switching up to 5 amps at 120VAC and is fuse (5a, 250v, slow blow) protected.
Ionizer motion sensor used with a bench top ionizer.Ionizer motion sensor used with overhead ionizer with sensor unit mounted on workstation shelf.
The ionizer motion sensor uses a unique infrared light and band pass filter to prevent interference from other light sources. The band pass filter uses a reflected infrared light with the specific frequency to sense the presence of the operator. It does not require continuous motion to remain active. The deactivation delay time can be set to 1 minute, 10 minutes, or 1 hour periods. This delay prevents the ionizer from turning on and off frequently if an operator is only away from the workstation momentarily.
Compatible with the following 120VAC Desco Ionizers: 60500, 60505, 60640, and 60473.
While there is no direct link between protection from ESD and protection from moisture, many devices and components require protection from both. Statshield Moisture Barrier Bags (MBB) are designed to protect the contents from both moisture and ESD events. MBBs protect ESD susceptible devices by forming a faraday cage around the contents and they protect…
Using a current limiting resistor in the ground cord is the user’s choice; however, the resistor is not for ESD control purposes. The ESD Association standard for grounding is ANSI/ESD S6.1. ANSI/ESD S6.1 recommends a hard ground (no resistor), but allows the use of a current limiting resistor in the mat’s ground cord. “The grounding…
