Mini Vise for PCB, Electronics & Soldering | Compact Workbench Clamp

Mini vise for electronics, PCBs and small workpieces — a compact bench clamp that holds your PCB, Raspberry Pi, ESP32, Arduino, or other small components rock-solid while you solder, test, repair, or assemble. Adjustable jaws with a smooth-running thumbscrew ensure quick setup and a secure grip every time.

Perfect for hobbyists, DIY enthusiasts, electronics makers, jewelers, and anyone who needs a third hand at the workbench.

Why use a mini vise?

Soldering, testing, or repairing small PCBs while they slide around the desk is frustrating and risky — cold solder joints, slipping probes, burnt fingers. A proper mini vise holds the workpiece flat at desk height, freeing both hands for the precision work. The low-profile design fits easily under a microscope or magnifier and keeps your PCBs in focus. The jaws are wide enough to hold Raspberry Pi-size PCBs, ESP32 dev boards, Arduino, breakout boards, and most through-hole or SMD PCBs up to about 8 cm wide.

Features

• Smooth thumbscrew clamp — open and close with one hand
• Wide jaw opening — fits PCBs, dev boards, small enclosures, jewelry parts
• Low-profile design — sits flat on the bench for stable soldering
• Stable wide base — doesn't tip when you press down on the workpiece
• Non-conductive jaws — safe contact with electronics
• Compact size — fits in any drawer or tool roll
• Quick adjustment — switch between PCB sizes in seconds

FAQ

What size PCBs can it hold?
The jaws open to about 8 cm, which fits most standard PCBs including Raspberry Pi (all models), ESP32 dev boards, Arduino Uno/Nano/Pro Mini, most breakout boards, and small custom PCBs.

Is it heavy enough to stay put?
For most hobby tasks, yes. If you apply significant force (drilling, filing), you can place it on a non-slip mat or screw it down to your desk through the slots in the base.

Can I clamp non-electronics with it?
Yes — it works just as well for jewelry, model parts, miniatures, and any small object that fits between the jaws.
