What it does: Holds 25 standard boards on edge and apart, at the bench, on the cart and on the shelf.
The problem it solves: Standard 1.6 mm (0.063 in) boards stand upright in a close-fitting slot instead of leaning in a wide one.
What it fits: Boards from 50 × 50 mm to 400 × 260 mm (2 × 2 in to 15.7 × 10.2 in), up to about 1.6 mm (0.063 in) thick.

Details

Standard boards, standing straight.

A close-fitting slot for 1.6 mm (0.063 in) boards, the standard board thickness.

The engineer, who chooses it: Sized for standard 1.6 mm (0.063 in) boards, with room for boards up to 400 × 260 mm (15.7 × 10.2 in).
The operator, who uses it: Each board drops into its own slot and stands upright, 15 mm (0.59 in) from the next, so it comes out without touching its neighbors.
The buyer, who pays for it: A pack of ten, priced on the page, in stock and shipped within a day. Conductive 10⁴ Ω, with ESD and RoHS test reports on request.

Description

The RA-16C is an ESD PCB tray: a 25-slot conductive polypropylene slotted-edge rack for standard-thickness PCBs.

Each slot is 1.7 mm (0.067″) wide and 4 mm (0.157″) deep, on a 15 mm (0.591″) pitch. Boards up to 1.6 mm (0.063″) thick drop in freely and stand straight, with zero surface contact between assemblies.

Boards up to 400 × 260 mm (15.75″ × 10.24″) span the 160 mm (6.30″) rack width and may overhang both sides, so panels wider than the rack body are fully supported. At 0.34 kg empty, it moves loaded between workstations without operator fatigue. Conductive PP at 10⁴ Ω keeps boards protected through production, inspection and storage.

Best uses

At the bench: Boards wait on edge, apart, between process steps.
On the cart: Boards ride upright from one station to the next.
On the shelf: Boards stay upright and apart in storage.
Next to the depaneler: Single boards go straight into a slot as they come off the panel.

Why factories use PCB racks

A board is most at risk while it waits between steps: static, scratches, bent edges and mix-ups.
A rack holds every board upright and apart, each in its own slot.
A conductive rack carries static away instead of letting it build up on the boards.
The boards in one rack are worth far more than the rack.

The polypropylene itself is conductive, so static is carried away instead of building up on the boards. RoHS compliant. ESD and RoHS test reports on request.

IPC and industry standards

IPC-1601: The IPC guideline for handling and storing printed boards: keep them clean, dry and protected from damage between fabrication and assembly. Our racks are conductive, 10⁴ Ω.
IPC/JEDEC J-STD-033: The moisture-sensitive-device handling standard. It sets the bake profiles (typically 90–125 °C) used to drive moisture out of MSD boards before reflow, which is why a rack's temperature rating decides whether boards can stay in it through the bake.

FAQ

Questions

Will my boards fit?

Boards up to 400 × 260 mm (15.75″ × 10.24″) fit, down to 50 × 50 mm (1.97″ × 1.97″), at up to 1.6 mm (0.063″) thick. Boards span the 160 mm (6.30″) rack body and may overhang on both sides, so panels wider than the rack are still fully supported in the slots.

Will a standard 1.6 mm (0.063″) board bind in the 1.7 mm (0.067″) slot?

No. The 0.1 mm (0.004″) clearance is intentional: boards drop in and out freely but stand straight without rattling. For thicker boards (heavy-copper, multilayer up to 2.4 mm (0.094″)), use the RA-24 Mini with its 3.2 mm (0.126″) slot.

Is it ESD-safe for our EPA workstations?

Yes. Conductive polypropylene, 10⁴ Ω. ESD and RoHS test reports are available on request for your audit file.

How does it ship, and how fast?

It ships as a pack of 10 racks from US stock; in-stock orders ship in under 24 hours. Shipping is calculated at checkout from the weight of the order.

Can it go through an oven or reflow?

No. This is a room-temperature bench and shelf rack rated −10 °C to +80 °C. For bake, cure, or reflow, use the magazine racks: 200 °C (GM/M) or the all-aluminum 300 °C HT Series.

Does it work with SMT loaders and unloaders?

No, the RA-16C is a bench-side and shelving rack for manual handling, not an in-line magazine. If you need loader compatibility, look at the B0103–B0109 magazine racks with the 50-slot loader interface.

How do I clean it without ruining the ESD surface?

Warm water with a mild pH-neutral detergent; IPA 70% for spot cleaning. Never use acetone, aromatic or halogenated solvents, or abrasives: they attack the conductive surface, and the damage does not reverse. Dry fully before boards go back in.

Where do I get the spec sheet or CAD?
