Key benefits Secure, stable hold: multiple clamping-port sizes match different motherboard thicknesses so boards stay firmly in place and do not shift during work. Accurate angle positioning: a rotating chuck with an elastic knob lets you fix the motherboard at the precise angle needed for soldering, inspection, or component replacement. Safe contact surface: clamping ports have a flat, burr-free surface designed to minimize scratches and protect PCB traces and components. Versatile sizing: adjustable opening distance accommodates a wide range of motherboard dimensions for use across many board types. What this product does for you Prevents movement and misalignment while you solder, test, or repair, reducing rework and component damage. Enables repeatable, stable positioning at custom angles for improved access and visibility. Protects delicate boards with a smooth clamping surface that reduces the risk of mechanical damage. Key features and specifications Multiple clamping-port specifications: compatible with motherboards of different thicknesses. Rotating chuck with elastic knob: locks the board at the desired angle quickly and securely. Flat, burr-free clamping surface: designed to avoid scratching or cutting the PCB. Adjustable opening distance: suitable for clamping various motherboard sizes and form factors. Typical applications Repair and rework: hold the motherboard steady during desoldering, component replacement, or hot-air rework. Assembly and testing: position boards for connector seating, cable routing, or functional testing without movement. DIY builds and upgrades: secure PCBs for installation of heatsinks, standoffs, or modular components. Usage notes Match the clamping-port specification to your board thickness before tightening to ensure a firm, even grip. Use the elastic knob to set and lock the preferred working angle; recheck tightness before applying soldering or mechanical force. This clamp is designed to provide reliable, non-damaging support and precise positioning for motherboards and PCBs during repair, assembly, and testing tasks.
