Read very funny article SMT Soldering Nightmare which ends with:
“You should get an ESD-specified soldering iron”. How can you check? Use a Menda Soldering Tip Voltage Tester.

|
- Alarms when voltage is over 1.25V.
- When the tester alarms it is typically detecting an ungrounded or improperly grounded solder iron tip.
- It can be used with ANY brand of soldering irons, tweezers and/or power tools
- Has both an audible and visual alarm
- Battery powered with 2 – AAA batteries
- No adjustment or calibration necessary
- Made in the United States of America
This item is made and stocked in Chino, CA.

ESD Handbook TR20.20 section 4.3.3.2 Tools and Equipment checklist includes: “4. Are soldering irons tested for tip to common point ground potential to prevent EOS damage to components?”
“The working part of AC powered tools should be capable of providing a conductive path to ground. New powered hand tools such as soldering irons typically should have a tip to ground resistance of less than 1.0 ohm.” (ANSI/ESD S20.20 Paragraph 6.2.6.1. AC Powered Tools)
“Most soldering irons should be hard grounded (i.e. <5 ohms) and ESDS should be grounded before coming into contact with the tips. This hard ground is needed because the vast majority of soldering irons have some form of temperature control, either by switching the iron on or off at limits, or by using high frequency effect. These control mechanisms can produce electric fields and thus require a low impedance path to ground to prevent high potentials from being accumulated which can damage ESDS (ESD sensitive items).” (EN 61340-5-2 Section 5.2.10)
