Stability and grip Metal structure with ABS blend provides a strong, lightweight grip, while a rubbergasket base keeps the workstation stable and prevents unwanted movement during precise soldering tasks. Flexible board range Adjustable clamp spans 0300 mm with four slot sizes: 1.2 mm, 1.8 mm, 2 mm, and 3 mm to fit varying PCB thicknesses. This lets you secure different boards for assembly or without changing tools. 360 degree rotation and positioning SN390 PCB Holder features a 360degree rotatable chuck with a tensionadjust knob, allowing you to lock the board at angles for component positioning and improving accessibility and workflow on complex projects. Portable and compact Weighs 0.69 kg and measures 408 x 170 x 125 mm, making it easy to carry between workstations or store when not in use. Suitable for onsite and bench work. 23 practical use scenarios Bench soldering and assembly: clamp boards of various thicknesses securely, adjust the angle for easy access to components, and hold the PCB steady during precise soldering operations. Onsite and rework: portable fixture that can be moved between locations; quickly clamp and reorient boards to reach underside or tight components without tools. Prototyping and inspection: set the board at the most convenient angle for inspection, layout verification, or iterative testing while keeping it stable.
