In the fast-paced world of electronics manufacturing, efficiency and protection go hand in hand.
Whether you are managing a high-volume SMT line or handling delicate prototype assemblies,
how you store and transport PCBs directly impacts your yield and workflow speed.
Introducing the SK350 3-Columns ESD SMT Trolley Cart—a purpose-built storage solution
designed to meet the rigorous demands of modern electronics production.
Engineered for ESD Safety
Static damage is an invisible threat to electronic components.
This cart is built from a combination of Stainless Steel and conductive PP Plastic,
ensuring full electrostatic discharge (ESD) protection. With a surface resistance range of 10⁶ – 10⁹Ω,
the cart falls within the ideal static-dissipative range,
allowing charges to bleed off slowly and safely to ground
without risking sudden spark discharges that could damage sensitive components.
The safety features extend to mobility:
4-inch ESD Rubber Wheels provide smooth, static-safe movement across the facility.
Conductive Chain ensures a continuous ground path when stationary,
maintaining EPA (ESD Protected Area) compliance at every workstation.
High Capacity, Compact Footprint
The SK350 is designed to optimize floor space without sacrificing storage capacity.
It features 3 columns of storage slots, each capable of holding 100 PCBs,
for a total capacity of 300 boards in a single unit.
Dimensions (L x W x H): 900 × 550 × 1260 mm
Side Panel Length: 350 mm—accommodating a wide range of PCB sizes
Precision Slot Design for Maximum Protection
The quality of a PCB rack lies in its slot design.
Poorly designed slots can lead to board warping, solder joint damage, or component scraping.
The SK350 utilizes precision-engineered slots to ensure your boards remain secure and damage-free:
Slot Width: 4.5 mm – ideal for standard PCB thicknesses (1.0–3.0 mm)
Slot Depth: 5 mm – provides secure retention while allowing for easy plug-in insertion
Slot Distance (Pitch): 10 mm – offers ample clearance for soldered components and tall parts,
preventing contact between adjacent boards
Panel Thickness: 10 mm – ensures structural rigidity, preventing warping or flexing even when fully loaded
Versatility Across Your Workflow
As highlighted in our product visual, the SK350 is more than just a storage cart—
it is a workflow optimization tool. Its versatile design allows it to serve multiple functions across your facility:
SMT Line Buffer: Stage PCBs waiting for pick-and-place or reflow ovens.
Inter-Workstation Transport: Safely move assembled boards between manufacturing, testing, and inspection areas.
Temporary Storage: Provide organized, static-safe storage for work-in-progress (WIP) inventory.
The "plug-in" slot design allows operators to quickly load or retrieve boards with one hand, reducing handling time and increasing throughput.
