Product: Circuit Board Holder Key benefits — why you need it Stable, repeatable positioning for safer, faster repairs: five adjustable clamping mouths hold different motherboard thicknesses securely, reducing movement while you solder or test. Full-angle access for precise work: the tightening knob allows 360-degree rotation so you can lock the board at the ideal angle without handling the PCB directly. Flexible sizing to match your project: extend the holder up to 200MM for larger boards; use the included soldering stand to secure circuits at 170MM for typical hand-soldering tasks. Heat and slip protection: anti-slip rubber pads increase friction to keep boards steady and help reduce the risk of burns; the removable soldering-iron stand is made from high-temperature resistant materials and fits most soldering iron pens. Features and specifications Clamping: 5 adjustable clamping mouths to accommodate a range of motherboard and PCB thicknesses. Rotation: 360-degree rotation with a single knob for quick angle adjustments and secure locking. Size range: Adjustable to a maximum of 200MM; soldering stand holds circuits at 170MM. Materials: High-temperature resistant components on the soldering stand; anti-slip rubber pads on contact surfaces. Compatibility: Removable soldering iron stand supports most standard soldering iron pens. How it solves common problems Eliminates board movement that causes poor solder joints or rework by firmly clamping diverse PCB thicknesses. Reduces hand fatigue and improves precision by allowing you to rotate and lock the board at the best working angle. Keeps tools and boards safe from accidental slips and heat exposure with rubber pads and a heat-resistant iron stand. Practical use scenarios Phone and laptop motherboard repair: Secure thin, delicate boards in the five adjustable clamps to solder ICs, replace connectors, or reflow components with steady positioning. Prototype assembly and hobby electronics: Hold development PCBs at any angle for accurate component placement, wire routing, and inspection. Small-scale production and diagnostics: Lock PCBs at 170MM on the soldering stand for batch soldering or troubleshooting while keeping irons and boards isolated from accidental contact. What to expect in daily use Quick setup: clamp the board, position with the knob, and lock the angle in seconds. Reliable performance: anti-slip pads keep components stable throughout soldering and testing cycles. Versatile support: the removable, heat-resistant soldering-iron stand fits most pens and keeps your workspace organized and safer. Purchase considerations Designed for a range of motherboard thicknesses via five clamping mouths; check your board dimensions against the 200MM maximum and 170MM soldering-stand capacity. Intended for hand soldering, testing, and repair tasks where stability, angle access, and heat resistance are important. This circuit board holder provides stable clamping, full-angle control, flexible sizing, and heat-resistant support to streamline PCB repair, soldering, and assembly tasks.
