The Ultimate "Third Hand" for Electronic Repairs
Soldering requires precision, and a moving circuit board is a recipe for mistakes, burned components, or damaged traces. The SN-390 Adjustable PCB Soldering Clamp Holder solves this problem instantly. Designed for engineers, DIY enthusiasts, and STEM educators, this rigid fixture holder keeps your workspace organized and your hands free.
Built for Stability and Precision
Weighing just 450g, the SN-390 strikes the perfect balance between portability and heavy-duty stability. The solid metal base is equipped with four anti-slip rubber feet, ensuring the rig stays exactly where you put it on your workbench. No more chasing your project across the desk while trying to apply solder.
Fully Adjustable for Any Project
Whether you are working on a tiny sensor module or a wider computer motherboard, this clamp holder adapts to your needs.
- Customizable Width: The retractable stand extends to securely hold printed circuit boards (PCBs) up to 200mm wide and 140mm high.
- Multi-Thickness Support: The spring-loaded clamps feature four distinct slots (1.2mm, 1.8mm, 2.0mm, and 3.0mm) to accommodate standard and custom board thicknesses.
360° Rotation for Flawless Soldering
Stop awkward wrist bending. The ABS clamping arms allow you to rotate your PCB a full 360 degrees. You can easily flip the board over to inspect cold solder joints, apply flux, or desolder components, then lock it back into place effortlessly.

FAQ Section
FAQ Section
Q. Will the heat from my soldering iron melt the clamps? The holding arms are made of high-heat-resistant ABS plastic. While direct contact with a soldering iron tip will melt them, standard soldering heat transferred through the PCB will not cause any damage.
Q. Can this hold a standard ATX computer motherboard?
The maximum clamping width is 200mm (20cm). It is perfect for smaller electronics, mobile device logic boards, and STEM microcontrollers, but a full-sized ATX motherboard will exceed the maximum width.
Q. Is the base heavy enough to stay put?
Yes. The solid metal base combined with four rubber friction feet provides excellent grip and stability, even when applying pressure with desoldering pumps or tweezers.
