Anti-Static PCB Basket Trolleys by Southern Machinery

Between the pick-and-place line and the wave-soldering line, bare boards are at their most vulnerable. They are moved, stored, queued, and re-kitted many times, and every unprotected transfer adds static damage, scratches, mixed WIP, and wasted operator minutes. Off-the-shelf racks that ignore your board size only make things worse. The fix is a sized, ESD-dissipative trolley that carries boards in separated slots from one station to the next.

Why unprotected board handling costs you

The losses show up in audits and rework, not in a single alarm:

• ESD damage at every transfer. Boards moved on bare metal build static that silently degrades sensitive ICs before they reach the line.
• Scratched and bent boards. Loose stacking and mismatched trays are the top cause of WIP damage.
• Operator time lost to fetching. Carrying boards one tray at a time pulls people away from placement and soldering.
• Audit-visible chaos. Non-ESD carts and mixed WIP fail customer 5S and ESD audits immediately.

The WIP Basket Audit

A named method to make board transport a controlled, repeatable step instead of a risk.

1. Size. Measure board dimensions (length × width × thickness) and daily WIP volume. Off-the-shelf racks that ignore your board size create more clutter than they cure, so specify every trolley to your parts.

2. Separate. Give each board its own slot so boards never touch each other. Charges drain through ESD-dissipative surfaces instead of building on the board, removing the silent damage path.

3. Route. Plan one-trip kitting of 8 to 24 baskets per trolley between stations. This eliminates the repeated walk-and-fetch trips that steal time from value-added work.

4. Audit. Label and segregate baskets so the floor stays 5S- and ESD-ready. Customers can see the discipline, and wrong-part assembly drops along with it.

How the trolley series maps to your line

Southern Machinery builds the audit into three frame options sharing one ESD basket system:

• Welded frame — one-piece stainless, maximum rigidity for high-load, double-sided use.
• Detachable frame — baskets remove individually and can be bought separately for flexible reconfiguration.
• Heavy-duty stainless steel 201 — economical heavy build (304 optional).
• Basket count — 8 / 10 / 12 / 16 / 20 / 24 hanging baskets, 4–12 tiers, single or double-sided access.
• Basket material — ESD-dissipative PP; reference size 410 × 280 × 160 mm holding about 38 PCBs, per-basket load 15 kg.
• Slot-plate option — 350 / 460 / 530 / 630 plates at 900 × 550–700 × 1280 mm, 200 to 600 PCBs per set, adjustable column spacing.
• Wheels — two directional brake wheels plus two universal swivel wheels: stable when parked, easy to push when loaded.

Exact tiers, basket counts, and slot dimensions are confirmed against your board sizes and line layout.

The trolley series is board handling — the connective tissue between SMT, THT, and inspection equipment. In a typical flow, the SMT placement line feeds ESD basket trolleys or magazine racks, boards stage at the wave line, then soldered boards move to inspection, rework, or final assembly. Southern Machinery, founded in 2011 in Shenzhen, China, supplies SMT, THT, wave soldering, board handling, and inspection equipment to 237+ global customers, so the trolley matches the conveyors, loaders, and unloaders on the same line.

Where this trolley fits your line

• SMT to THT transfer — move populated boards from placement to wave soldering without scratching or mixing batches.
• Line-side WIP storage — keep 8–24 baskets of in-process boards at the station with single or double-sided access.
• High-density interim storage — slot-plate turnover cars hold 200–600 PCBs per set for batch changeover or inspection queues.
• ESD-critical product groups — automotive, medical, industrial control, and other high-reliability electronics where static damage is unacceptable.
• 5S and audit readiness — labeled, separated ESD storage that survives customer audits.

Buyer checklist

1. Board dimensions (length × width × thickness).
2. Daily WIP volume and batch sizes.
3. Basket storage vs. slot-plate preference.
4. Aisle widths and cart fleet compatibility.
5. Number of tiers / baskets and single vs. double-sided access.
6. ESD requirements and audit expectations.

Before you commit, share your PCB dimensions, daily WIP volume, and line layout with our inquiry team. The engineering team will confirm the fit — whether a standard configuration or a custom build — and provide installation support, training, and spare baskets, casters, and plates after delivery. A correctly specified trolley turns board handling from a recurring source of ESD risk and rework into a controlled, auditable step that protects yield on every transfer between stations.

Run the loop

Re-run the WIP Basket Audit whenever board dimensions, batch sizes, or aisle widths change, and before every customer 5S or ESD audit. That loop keeps separation, routing, and labeling current so board handling stays a controlled process rather than a recurring finding.

Your next step

Email your PCB dimensions, daily WIP volume, and line layout to info@smthelp.com for a confirmed trolley configuration and quotation, typically returned the same working day.

FAQ

What is the difference between the three frame styles?

Welded frames give maximum rigidity for high-load double-sided use; detachable frames let you remove baskets for flexible reconfiguration; the heavy-duty stainless 201 build is the economical heavy option. All three share the same ESD PP basket system and 2+2 caster layout.

What makes these trolleys ESD-safe?

Boards sit in ESD-dissipative PP baskets or anti-static slot plates on a metal frame, so charges drain instead of building up, and boards stay separated.

How many PCBs can one trolley carry?

A reference basket (410 × 280 × 160 mm) holds about 38 boards, and frames carry 8 to 24 baskets. Slot-plate carts hold 200 to 600 boards depending on the 350–630 slot option.

Can the trolley be customized?

Yes. Frame length, tier count, basket count, slot-plate size, and wheel layout can all be customized against your board sizes and line layout.
