SBF330 Wave Solder Input Conveyor for Synchronized THT Infeed

Before wave soldering, someone usually has to feed each board or pallet into the machine by hand — and the moment that feed rate drifts, solder defects climb and the whole THT line stutters. Manual loading is hard to pace, easy to interrupt, and it puts a person right next to an open wave. The SBF330 input conveyor transfers PCBs and pallets into the wave solder inlet on a synchronized, variable-speed run, so the solder machine sees a steady stream instead of an uneven one.

The cost you haven't named: the manual wave-solder feed

• Feed rate drift creates solder defects. When an operator hands boards in unevenly, the wave sees gaps and rushes, producing skips, icicles, and bridging that show up only at inspection.
• An operator is pinned to a hot machine. Standing at the wave inlet is a low-value, high-exposure task that keeps a person next to molten solder for an entire shift.
• Pin-chain compatibility gets ignored. Many THT pallets ride on pin chains with 3 mm or 5 mm pins; a generic conveyor that cannot match the pitch forces manual workarounds.
• Line balance breaks at the boundary. The wave is only as smooth as its infeed, so a manual hand-off becomes the variable that destabilizes the entire THT throughput.
• Changeovers take longer than they should. Without an adjustable incline and guide rail, re-bearing different pallet sizes means improvising rather than setting a repeatable geometry.

The Infeed Synchronization Audit

1. Trace the feed hand-off. Walk the path from the last THT station to the wave inlet and note every manual lift. Each hand-off is a point where pace and quality can slip.

2. Measure the board and pallet window. Record PCB size, thickness, and pallet type, including whether your pallets run on 3 mm or 5 mm pin chains, so the conveyor pitch and rail match the load.

3. Set the speed lock. Define the infeed rate the wave machine needs and confirm the conveyor can hold it with variable speed control tied to the solder machine, not to an operator's rhythm.

4. Confirm the incline and rail fit. Check the inlet height and the guide geometry. An adjustable incline and aluminum guide rail let the conveyor meet the wave at the right angle without a custom bracket.

The vehicle: SBF330 Wave Solder Input Conveyor

The SBF330 is an input conveyor that transfers PCBs or pallets into the wave soldering inlet, replacing manual loading at the THT line boundary.

• Trace the feed hand-off → hands-off infeed. Boards and pallets move into the wave on the conveyor, removing the manual lift that sits between the operator and the open wave.
• Measure the board and pallet window → 50 × 50 to 445 × 330 mm range. The unit handles boards from 0.6 to 4 mm thick and up to 1.5 kg, covering most THT pallets without a special carrier.
• Set the speed lock → synchronized variable speed. A variable-speed drive runs 0.5 to 20 m/min and can be paced to the solder machine so the wave stays fed at a constant rate.
• Confirm the incline and rail fit → adjustable incline, aluminum guide rail. Pin-chain transport with 3 mm or 5 mm pins and an adjustable incline let the conveyor meet the inlet geometry repeatably.

Specification note: exact transport height, incline range, and pin pitch should be confirmed at quotation, because they depend on your wave machine model, pallet design, and local voltage.

The loop: re-audit the infeed every quarter

THT product mixes change with every new board family. Build a loop: every quarter, re-run the Infeed Synchronization Audit, compare wave-defect counts against the baseline, and review how often the infeed speed had to be re-tuned by hand. If a new pallet type arrives with a different pin pitch or board size, confirm the conveyor setting at quotation before it reaches the wave. The SBF330's adjustable rail and incline mean it stays useful as pallets evolve — the loop is what keeps the infeed matched to the solder machine instead of drifting back to manual pacing.

FAQ

What does the SBF330 do?

It transfers PCBs and pallets into the wave soldering inlet on a synchronized conveyor, replacing manual board feeding at the THT line.

What pallet pitches does it support?

Pin-chain transport with 3 mm or 5 mm pins, so it matches common THT pallet designs.

How fast can it run?

Conveyor speed is variable from 0.5 to 20 m/min and can be synchronized with the wave solder machine.

What board sizes fit?

PCB size runs from 50 × 50 to 445 × 330 mm, with thickness from 0.6 to 4 mm and up to 1.5 kg per board.

Is a larger version available?

Yes. The SBF460 handles PCBs up to 530 × 460 mm and weighs 45 kg for wider pallet work.
