A practical guide to picking PCB conveyors, loaders, unloaders, and buffers for smoother SMT automation, with tips on SMEMA/Hermes and WIP control.
If you’re planning SMT line automation, PCB handling is where the line either flows… or it chokes. One weak conveyor, one buffer that’s “kinda” wrong, and suddenly your fancy printer and pick-and-place sit there waiting. Not fun.
Also, don’t forget the boring stuff. You still need storage, racks, and clean flow around the line. That’s where componentes para câmaras frigoríficas and solid shelving layouts quietly save your day (more on that later).
Before you pick a machine, pick a target. Sounds obvious, but people skip it.
Pergunte a si próprio:
Here’s the truth: if you don’t name the bottleneck, you’ll buy the wrong tool. Then you’ll blame the vendor. Been there, seen that, it happens a lot.
“PCB handling machines” isn’t one thing. It’s a set of building blocks:
Think of it like traffic. Conveyor is the road. Buffer is the parking lot. Loader is the on-ramp. If you build a road with no parking, your line will still jam.
A PCB conveyor looks simple, but it decides daily uptime.
Start with board size and board stiffness:
If your boards are flimsy, a “standard” edge-rail conveyor can scratch, flex, or just mis-track. Then you get random stops that nobody can explain. Super annoying.
If you run high-mix, changeover speed matters more than people admit.
Procurar:
If changeover takes 10 minutes and you do it 10 times a shift… your “automation” feels like manual work with extra steps.
Ask about:
A conveyor that clears jams fast keeps operators calm. A conveyor that doesn’t… makes your floor feel cursed.
Loaders/unloaders are the quiet guardians of steady flow. Pick the wrong magazine setup and you’ll get constant babysitting.
Confirm:
If your magazines vary (and they will), you need tolerance. Otherwise you’ll get that classic “works on day one, breaks on day two” vibe.
Don’t just ask “how fast.” Ask “how it syncs.”
A loader that pauses the whole line for magazine changes is basically a line-stop button with wheels.
Buffers save lines, but only when they match your process logic.
This is where “WIP is king” thinking can trap you. Too much buffer hides problems. Too little buffer makes every micro-stop turn into a big stop.
A good buffer plan keeps WIP controlled, not exploding like popcorn.
You don’t want integration drama. Yet… it happens.
SMEMA works for basic board transfer handshakes. It’s common, it’s simple, it’s everywhere.
But SMEMA doesn’t carry rich board data. So if you want stronger traceability, you’ll need extra steps (barcode systems, middleware, manual mapping).
Hermes-style thinking pushes board ID + data to move with the board, not just a “ready/not ready” signal.
In mixed lines, you may run SMEMA on older machines and Hermes-ready systems on newer ones. That’s normal. Just plan it early, or you’ll be doing last-minute cable wizardry at 2 a.m.
If you care about real automation, you care about control.
Procurar:
A machine that only says “Error 37” is not your friend. You want plain language alarms, even if the English is a bit weird.
A perfect machine that nobody can service is a bad machine.
Check:
Leave room for humans. Your techs still need to work, eat, and breathe. If they can’t reach a sensor, they’ll bypass it. Then the line gets spooky.
Here’s the part most PCB handling guides ignore: materials handling around the line.
If you run solder paste, adhesives, or other temperature-sensitive materials, you likely use armazenagem frigorífica. If armazenagem frigorífica is messy, the line gets messy too. Then FIFO breaks, labels fall off, and someone grabs the wrong jar. Oops.
É por isso que Estantes de arame multicamadas para câmaras frigoríficas matters in automation projects. You’re not just moving boards. You’re managing the whole flow system.
If you need corrosion-resistant finishes, stable load capacity, and a layout that actually supports FIFO, check this product category:

And yes, this ties back to your PCB line. A clean cold room setup reduces wrong-material events, and those events cause line stops. Simple.
| Machine Type | Melhor para | Key Specs to Confirm | Common Pain Point |
|---|---|---|---|
| PCB Conveyor | Basic transfer between process stations | Board size range, width adjust, sensors, ESD options | Random jams, slow changeover |
| PCB Loader | Feeding boards into the line | Magazine type, pitch, clamp, misload detection | Magazine mismatch, line pause |
| PCB Unloader | Collecting boards after process | Swap time, buffer behavior, detection | Overflow, operator babysitting |
| PCB Buffer | Micro-stop protection and WIP control | FIFO/LIFO mode, capacity logic, recovery | Hides bottlenecks, sequence issues |
| PCB Flipper | Top/bottom side process needs | Orientation control, timing | Misflip, wrong side runs |
| Diverter/Sorter | OK/NG routing, rework loops | Routing logic, sensors, traceability hooks | Wrong routing = chaos |
No cost numbers here, because cost changes fast and vendors play pricing games. Focus on fit first.
You want: fast width adjust, recipes, clear alarms, easy jam recovery.
If changeover hurts, your output will feel “stuck” even when machines are fast.
You want: reliability, simple handshakes, strong magazine handling, low downtime parts.
Here, a basic setup can beat a fancy one, if it runs clean.
You want: scan points, board ID flow, and consistent FIFO handling.
If you miss this, you’ll spend months patching data holes later.
Choosing PCB handling machines isn’t a shopping trip. It’s system design.
Start with bottlenecks. Then pick functional blocks. Confirm board support. Decide FIFO/LIFO. Plan SMEMA vs Hermes integration. Protect changeover time. Keep layouts serviceable. And don’t ignore storage flow—your cold room shelving and material control can quietly make or break the line.
