As circuits get smaller and more compact, they have also become more susceptible to electrostatic discharge (ESD) and damage. According to the ESD Association, 25% of all electronics that are ‘damaged for unknown reasons’ can be attributed to ESD. Further, it is estimated that the cost of ESD damage to the electronics industry is $5 billion per year. This puts ESD protection front and center of your electronic assembly process. The consequences of ignorance or neglect can manifest as permanent circuitry damage or latent failure. This reduces the reliability of your electronics and will result in lost customer confidence and business. It also drives up your production costs.
How to Ensure Maximum ESD Protection for Your Electronic Assemblies
ESD damage can be prevented in many ways. Our electronic assembly experts recommend 3 key levels of ESD protection for your electronic circuits.
- Create ESD protection zones: Electrostatic Discharge Protected Areas (EPAs) safeguard your ESD-sensitive electronics from any items that are likely to produce electrostatic discharge. This is done by grounding conductive materials and workers in the electronic assembly unit or zone and other susceptible manufacturing areas. Some of the measures involved in creating EPAs include using conductive flooring materials that will direct electric charges away from the work zone and anti-static mats. Workers’ clothing must also have conductive filaments. Setting appropriate humidity levels in the work facility also reduces static. Consult the American National Standards Institute (ANSI) and International Electro technical Commission (IEC) for prescribed standards.
- Built-in ESD protection for your circuits: ESD damage can occur at any stage of product development, and particularly during electronic assembly when the circuit boards have maximum exposure. In-built ESD protection reduces the risk of total circuit failure or latent damage. Since there are several types of transient circuit protection devices available, care must be taken to select one that matches your PCB parameters. For optimal protection, the suppressor must also be placed at the point of ESD penetration.
- ESD-controlled circuit board storage and transportation: It is important to understand that ESD damage could occur during the storage and transportation of your electronic circuit boards. One of the most commonly-used solutions to store and transport electronic circuits is an ESD bag. Modeled on the principles of the Faraday cage, these anti-static bags are made using fine layers of metal to seal the contents from external charges. Tubes and totes with similar covering may also be used.
