The Brush-Off: Which ESD Brush Is Best for You?

by Michelle R. on January 8, 2014

With a range of sizes, styles and material types, we’ve got an ESD brush suited for virtually any application. Commonly used in solder removal, dusting, board prep, ESD wiping, general cleaning and more, there are six main types of anti-static brushes.

Conductive – Used to reduce static charge to 0V in environments where rapid discharge is not harmful to the application. For example, brushes used inside copy machines are generally conductive.

Dissipative –Used wherever high current flow is damaging to the application, dissipative brushes are excellent for removal of static charge that results in the adhesion of particles to an object.

Low Charging – Ideal for environments where the creation of a minor charge is non-threatening. Low charging brushes do NOT remove an existing charge.

Insulative – This inexpensive alternative to conventional anti-static brushes is best for environments where static protection is non-critical. Brushes immersed in liquid offer additional ESD protection.

Cleanroom – Durable and non-shedding, these brushes are designed to withstand sterilization in cleanroom environments while eliminating static charge.

Thunderon– This special fiber is one of the softest synthetics available. Thunderon conductive fiber offers far greater control of static and superior overall performance.


Dial or Digital? Gauging the Right Option

by Michelle R. on December 25, 2013

Standard or plastic, waterproof or solar… with all the types of calipers available, finding the best fit for your application can seem overwhelming. The first step may be to determine whether a dial or digital version is right for you. Read on to discover the differences and benefits of each.

Dial Calipers Dial calipers use a gear system to move the dial in increments of one one-thousandth of an inch. Convenient and easy to use, dial calipers don’t require batteries and work well even when damp. However, they are easily knocked out of alignment if dropped, can be difficult to recalibrate, and are usually either imperial OR metric – but not both.

Digital Calipers Digital calipers are based on a capacitance system, and easily convert from inches to metric readings. Because gears are not involved, they are more shock-proof and won’t be knocked out of alignment. They can, however, become damaged or offer inaccurate readings if wet. Specially designed waterproof versions are available from brands like Mitutoyo for harsh fluid environments.


Made to Measure: Inside, Outside and Depth Micrometers

by Michelle R. on December 18, 2013

An industry staple for many precision applications, micrometers are an essential for trades ranging from inspection to mechanical engineering and are designed for accuracy to the closest one thousandth of an inch.  But when it comes to micrometers, one type doesn’t fit all. Three commonly used varieties include inside, outside and depth micrometers. Read on to discover which type is best for your application.

Inside Micrometer – Designed to measure the inner diameter or the width of a recess such as the inside of a tube or holes, cylinders, bearings and bushings.

Outside Micrometer – Used to measure the outer diameter of a cylindrical or spherical object, such as a piece of round stock or tubing.

Depth Micrometer – Essential for measuring the depth of holes and recesses including slots, steps, shoulders and projections.
