FR1004 ESD Cart

ESD Cart: A Complete Guide

An ESD (Electrostatic Discharge) Cart is a mobile storage and transport solution designed to protect static-sensitive electronic components from electrostatic discharge. These carts are commonly used in electronics manufacturing, PCB assembly, laboratories, cleanrooms, and semiconductor facilities to ensure safe handling of electronic parts.

1. Key Features of an ESD Cart

a) ESD-Safe Materials

• Constructed using conductive or static-dissipative materials, such as:

  • Powder-coated metal or stainless steel (for durability and grounding).

  • ESD-safe plastic or laminate shelves (for non-conductive storage).

  • Aluminum frames for lightweight and corrosion resistance.

b) Grounding System

• Equipped with ESD-safe caster wheels that allow static charge to dissipate into the ground.

• Some models include grounding chains or wrist strap connections for added protection.

c) Adjustable Shelves and Storage Capacity

• Available with two, three, or more tiers for organizing tools, PCBs, and electronic components.

• Some carts feature adjustable or removable shelves to fit different-sized items.

• Conductive foam or dividers may be included for safe PCB or component storage.

d) Mobility and Stability

• Swivel caster wheels provide smooth movement across work areas.

• Locking wheels ensure stability when stationary.

• Some carts include handles or push bars for easy maneuverability.

e) Compliance with ESD Standards

• Meets ANSI/ESD S20.20, IEC 61340-5-1, and ISO 14644 standards for static control and cleanroom compatibility.

2. Types of ESD Carts

a) ESD Utility Cart

• General-purpose cart used for transporting tools, trays, and components.

• Features multiple shelves and may include bins or drawers.

b) ESD PCB Cart

• Designed with vertical slots to securely hold PCBs during manufacturing and testing.

• Can accommodate 50 to 200+ PCB slots, depending on the model.

c) ESD Reel Cart

• Used for storing and moving SMT component reels in electronics assembly.

• May include angled racks or dividers to organize reels of different sizes.

d) ESD Work-in-Progress (WIP) Cart

• Holds partially assembled electronic devices during production.

• Designed for easy access and organization of work-in-progress items.

3. Where Are ESD Carts Used?

ESD carts are essential in environments where static-sensitive devices are handled, such as:

• Electronics Manufacturing – For transporting PCBs, components, and tools.

• Semiconductor & PCB Assembly – For safely moving delicate circuit boards.

• Cleanrooms & Laboratories – For contamination-free material handling.

• Warehouses & Storage Areas – As a static-safe storage solution.

• R&D and Testing Facilities – For organized and protected component transport.

4. Choosing the Right ESD Cart

When selecting an ESD cart, consider:

• Material: Choose between powder-coated metal, aluminum, or ESD-safe plastic.

• Storage Needs: Decide on the number of shelves, slots, or bins based on usage.

• Mobility: Ensure the cart has lockable ESD-safe casters for smooth movement.

• Capacity: Check the cart’s weight limit to accommodate your equipment.

• Compliance: Verify that the cart meets ANSI/ESD and IEC static control standards.
