Anti Static Storage Circuit Board Strip Turnover Rack

Anti Static Storage Circuit Board Strip Turnover Rack

This is an open, fence style rack consisting of a series of parallel, slotted 'bar' support rods. It adopts an all metal structure and has undergone special anti-static treatment. Its main function is to safely transport and temporarily store PCB boards filled with components between different workstations on the production line (such as SMT, inspection, welding, assembly, and testing), preventing them from being damaged due to accumulation, collision, or static electricity during turnover.

Feature:

Anti-static
Core function: This is the most important attribute of the device. Ordinary metal frames can generate and accumulate static electricity, which is fatal to circuit boards.
Implementation method:
Material: Usually made of steel, but coated with special anti-static coatings such as epoxy resin anti-static paint through electroplating or spraying. This controls its surface resistivity within the range of 10 ^ 5~10 ^ 9 Ω, forming an electrostatic dissipation layer.
Grounding: The rack is designed with a dedicated grounding terminal (usually a copper core grounding post with a wiring knob), which must be connected to the factory's common grounding wire using a dedicated grounding wire. This can safely and quickly dissipate the generated static charges, providing an equipotential safe environment for the circuit board.
Storage and turnover
Dual use:
Turnover: The bottom is equipped with 4 high load-bearing universal wheels (usually at least 2 with brakes), making it convenient for workers to move the entire circuit board smoothly and easily in the workshop. This is the embodiment of its value in terms of 'flow'.
Storage: At the destination, it can be fixed by pressing the brake and used as a temporary storage rack, making it convenient for workers to access and place it in sequence, serving as a small workstation.
Circuit board
Design object: It is specified that its purpose is to store PCB boards of various sizes.
Adaptability: The spacing between support rods is usually adjustable to accommodate circuit boards of different widths, lengths, and thicknesses. Some designs can also adjust the tilt angle for easy operation.
Strip
Core design feature: This is not a solid board or box, but rather composed of multiple (usually 4-10) parallel metal bars.
Advantages:
Efficient heat dissipation: The circuit board may generate heat after soldering or testing, and the strip design ensures air circulation to help the board cool naturally.
Lightweight and material efficient: While ensuring load-bearing capacity, it is lighter than solid boards, reducing costs and making it easier to push.
Visibility and operability: Workers can easily observe the card number and status from the bar gap, and manually take and place it, which is very convenient.
(turnover) Rack
Overall structure: a complete mobile frame, typically consisting of:
Chassis frame: A sturdy base used for installing swivel wheels and supporting the entire upper structure.
Support column: a vertical column that connects the chassis and the strip-shaped support rod.
Bar shaped support rod: The core part directly supports the circuit board.
Edge protection/guardrail: There are usually guardrails around the bracket that are slightly higher than the PCB to prevent the board from slipping during movement.
