How to prevent ESD damage
By Dan Romanchik, KB6NU
Here are some tips from Keysight Technologies, one of the leading electronic test equipment companies, on how to prevent ESD from damaging your electronics.
USE A GROUNDED WRIST STRAP whenever you are handling equipment or boards. Using a grounded wrist strap prevents your body from building up charge and causing damage when this built-up charge discharges into your equipment or test boards. Make sure to connect that alligator clip to ground!
USE GROUNDED WORK SURFACES OR MATS for your boards. Do NOT use static generating or insulating materials as a work surface. Non-grounded mats and static generating/insulated materials can inductively charge boards, especially exposed ones. When connecting a charged board to equipment, the board can cause damage by discharging into the equipment’s inputs.
KEEP CHARGED MATERIALS AT LEAST 0.3 METERS FROM EXPOSED ASSEMBLIES. This includes plastics, foam, or other materials that can build up charge. Having a charged material near an exposed assembly can inductively charge the assembly. The assembly can then discharge into the equipment’s inputs.
DISCHARGE YOUR CABLES BEFORE CONNECTING THEM TO YOUR EQUIPMENT. Electrostatic charges can build up on test probes and test leads, so it’s import to discharge them before connecting them to your test equipment:
• Ensure your device is off.
• Connect your cable to your device.
• Attach a 50 Ω shunt to the open end of the cable.
• Remove the shunt and immediately attach your device to your equipment.
This prevents the center conductor of your cable from discharging stored charge into your equipment. A charged assembly can charge connected cables.
USE BOARD STANDOFFS AS NEEDED. In some situations, you need board standoffs to provide extra insulation for your exposed assemblies. This prevents your grounded mats from making unwanted connections on your board.
NEVER USE “PINK” PACKING MATERIAL FOR BOARD TRANSPORT OR AS A WORK SURFACE. While many people think pink packing material is ESD safe, in most cases it easily builds up unwanted charge. Unless continuous, thorough testing is done, treat pink packing materials as charged.
CAP UNUSED EQUIPMENT INPUTS to avoid accidental ESD and physical damage. Damage often occurs by accidentally contacting equipment inputs. Capping unused inputs protects them from incidental ESD damage.
USE ESD-SAFE BAGS WHEN TRANSPORTING BOARDS. This protects boards from ESD damage while moving between ESD-safe locations.
DO NOT OVERDRIVE EQUIPMENT INPUTS. Start your testing at the least sensitive input setting and zoom in on your signal. Additionally, observe the maximum input levels for your specific equipment. The least sensitive setting is the most resilient, so starting there ensures that your inputs are at safe operating levels
After I posted this to my blog, Dave, N8SBE offered some further tips. He writes:
Grounded heel straps also help reduce static charge. Test them with a floor tester every time you put them on. The floor needs to be somewhat conductive—not metal, that’s a safety hazard—so use conductive wax on tiles, or conductive carpet to drain of electrostatic charges.
Keep materials, such as styrofoam cups, that form electrostatic charges easily away from your workspace. A styrofoam cup can generate thousands of volts.
Keep the humidity up in the workspace. That helps to keep static generation down as well.
I like to think that I follow ESD-safe procedures, but there are a couple of things here that I hadn’t thought about before. For example, I’d never really thought about discharging test equipment cables before connecting them. I think that’s a good tip

Virtual Meeting, Fallbrook, California
December 5, 2020
Vice-President Ron Patten, KG6HSQ, called the Virtual meeting to order at 1504 hrs.
A pledge of allegiance was conducted by Ron.
Brent, KJ6UMY, gave the following financial report.
|Checking Balance October 31, 2020||$7,637.70|
|Petty Cash Balance October 31, 2020||$78.81|
|ARRL Renewal Fees||$94.00
|Petty Cash Balance October 31, 2020||$78.81|
|Expenses November 2020||$0.00|
|Cash Additions November 2020||$0.00|
|Checking Balance November 30, 2020||$7,661.70|
|Petty Cash Balance Nobember 30, 2020||$78.81|
Ron, KG6HSQ, reminded us that the annual elections are coming up in January and all three positions, President, Vice President, and Secretary/Treasurer are open for anyone interested.
Ron called for comments on the recent power shutdowns and their effects.
Hayden, KG6YVD, reported that the outage at his QTH lasted for 1.5 days during which time he ran on a recently acquired towable, 6 kw diesel generator. During the blackout, it used 4 gallons of diesel. Damage suffered at his QTH included the shade netting on his range taken out by a falling limb, his A3 antenna blowing down and the loss the roof on his chicken coop. Max wind speed recorded was 39 mph. All power has now returned to normal at his location.
Capt Don, W6PLT, suffered minimal damage at his location with some things blown around.
Ron, KG6HSQ, indicated that his power went off at 0200 hrs Wednesday and came back on at 1900 hrs on Thursday.
Bob, W6RMG, had an outage that lasted from 0500 until 2400 hrs on Wednesday. His 3600 watt generator operated his coffee maker and lights during the outage.
Ron, KG6HSQ, reported that the Red Mountain repeater was down for several hours during the shutdown. He reminded the club that the protocol in a Red Mountain outage was to move to the VHF output frequency with a backup of Simplex 5. Discussion also had mention of multiple occurrences of incomplete SDGE phone notifications.
Bob, W6VR, inquired about the operation of traffic signals during an outage.
Stephen, KC6MIE, observer that this was the first club meeting on the first Saturday in December in memory as it usually conflicts with the Christmas Parade. There was some indication that the Christmas Parade would be held with an alternate format.
Brent, KJ6UMY, gave a presentation on his new HF station, which included the antenna and radio installations.
Ron, KG6HSQ, presented the use of an SDR Play, SDR Uno software and add-on software to receive and decode DMR signals. Mike, KN6HTX, provided a test transmission we heard over the SDR system.
Hayden, KG6YWB, reported using SDR receiving stations, available on the internet, to monitor his transmissions monitor his signal as received at other locations.
Bob, W6VR, asked Bob, W6RMG, about the visibility of Starlink satellites.
Hayden, KG6YWB, is working on the repair of his Stepper IR antenna prior to erecting it.
Ron adjourned the meeting at 1631 hrs.
