Latex Gloves – Are You Allergic?


Many industrial manufacturing environments require workers to wear protective gloves, including during electronics and medical device production and assembly. Latex gloves not only protect workers from harmful chemicals but also protect products from worker contact and contamination during manufacturing Read more

ST 925 SMT Rework System–Three favorites combined into one nice savings


Save a few steps--and some money--with the Pace 925 SMT Rework System Pace has introduced a new low-cost “combination” system ideal for surface mount technology (SMT) rework. It’s worth adding up the savings by comparing the a la carte prices Read more

Metcal’s CV-5200 Connection Validation Soldering Station Changes Everything


You may or may not have heard about Metcal’s new soldering station, the CV-5200. The evolutionary tool removes much of the reliance on visual inspection of hand-soldered joints and adds a second, more technology-driven method for validating a successful Read more

ESD–Smaller Parts, Bigger Problems

ESD Sparks Conversation

It’s no shock that smaller electronic parts have been causing bigger ESD (electrostatic dissipation) problems–serious problems that cause component damage and money. How much damage depends on the sensitivity or susceptibility of the device.

Thankfully you can put controls in place to significantly reduce ESD incidents. Preplanning, understanding causes and solutions, and wearing special fabrics and components will help.

Preplanning

  1. Design products and assemblies to be as protected as practical from ESD damage
  2. Decide how much of the environment needs to be controlled
  3. Identify the areas needing protection and ESD sensitive parts
  4. Define the electrostatic protected areas (EPAs)
  5. Define the areas where ESD sensitive parts (ESDs) will be handled
  6. Eliminate static generating processes to reduce electrostatic charge generation; keep processes and materials at the same electrostatic potential; provide appropriate ground paths to minimize charge generation and accumulation
  7. Use grounding, ionization, and conductive and dissipative static control materials to dissipate and neutralize
  8. Use grounding, ionization, and conductive and dissipative static control materials to dissipate and neutralize
  9. Protect products from ESD with proper grounding or shunting, static control packaging and material handling products

Areas needing ESD protection

Causes and effective solutions

ESD is a tiny version of lightning. As the current dissipates through an object, it’s seeking a low impedance path to ground to equalize potentials. In most cases, ESD currents will travel to ground via the metal chassis frame of a device. However, it’s well known that current will travel on every available path.

Control the area

The first step is to ground all components of the workstation and the personnel (work surfaces, equipment, etc.) to the same electrical ground point, called the “common point ground” i.e., system or method for connecting two or more grounding conductors to the same electrical potential.

Bevco 7000 Silver Series Chairs: Durable and Comfortable

Looking for a durable and ergonomic chair that’s easy to care for? Try the Bevco 7000 Silver Series chairs. Bevco 7000 Series Silver Chair

The most distinguishing feature of the 7000 Silver Series chairs is the polyurethane seat and back. This durable polyurethane material is puncture resistant and repels water, grease and chemicals. Ease of cleanup and durability make the 7000 Silver Series chairs ideal for a variety of environments including laboratory, medical, industrial and cleanroom applications.

Like all Bevco chairs, the 7000 Silver Series chairs are designed with ergonomics in mind to help prevent fatigue and strain on workers’ bodies. Some of these ergonomic features include ventilation ribs to increase air circulation, a comfortable waterfall seat, contoured back rest and pneumatic seat height adjustment. In addition, the chair’s solid frame is supported by a five-legged polished aluminum base and the backrest is secured with a heavy-duty, spring-loaded chrome-plated back bar.

Bevco offers six different models of 7000 Silver Series chairs in gray, black and blue as well as a black ESD-safe version with standard ESD-safe glides, brass drag chain and ESD-safe polyurethane seat and back. The six different models offer various heights, with or without back and seat tilt, and with or without chrome foot ring. Also, all 7000 Silver Series chairs are certified for Class 10 cleanrooms.

All-Spec Industries is an authorized distributor of Bevco, manufacturer of standard and ESD-safe chairs for a variety of workspaces including industrial, laboratory, cleanroom and electronic assembly applications. Bevco has over 50 years of experience crafting durable workplace seating with outstanding comfort, and they back their chairs with a 12-year guarantee. Please visit All-Spec.com to see our entire selection or call Customer Service (800-537-0351) for more information, and remember all Bevco chairs are made in the U.S.A.
