There are many considerations when creating an ESD-safe work place and one of the biggest is reducing static electricity from humans. Wrist straps are the most common method of grounding an operator at a workstation, but there are some options to look into when purchasing them. An important, but often overlooked, factor is how the snaps are made.
Machined snaps are made by grinding or cutting a piece of metal into the shape needed. They benefit from increased precision, but can cost more than formed snaps.
Formed snaps are made by stamping a shape into a piece of metal. These can be made much faster and easier, so they tend to be cheaper, but you lose out on the exactness of the machined snaps.
Overall, formed snaps are good for most non-critical applications, especially if you normally sit at your workstation. If precision is important or if you find that your wrist strap accidentally disconnects, then you may want to look into machined snaps.
By using wrist straps with machined snaps you can prevent many accidental disconnects, and also have assurance that the snap will consistently provide a path to ground. Gene Bliley wrote an article for Evaluation Engineering on reducing accidental release problems for his company. It is an interesting read and shows how effective using machined snaps can be if you are having problems with formed snaps. There are many options on the market to get machined snap wrist straps, and if you want more protection some companies offer magnetic snaps.

Know The Numbers: The ESD Lab Wear you select should meet the best practices as set by the ESD industry. Make sure the garment has been tested per ESD STM 2.1 Method and has met the compliance standards required by ANSI/ESD S20.20.
Know The Performance: A quality ESD Lab Coat will be made of fabric that is breathable and comfortable. Make sure you select a garment that also retains its full ESD properties after many washings.
Know The Environment: Make sure the Lab Wear you select meets the criteria for a particular ESD device and the environment where it will be worn. This helps protect against unnecessary product loss.
Know the Manufacturer: Select ESD Lab Wear and Cleanroom garments made by an experienced company, known for quality. This ensures the manufacturer knows and adheres to the stringent requirements for ESD control. An experienced manufacturer can also design a custom style for a company’s unique ESD requirements.
