Adjustable Soldering Support Stand 360° Rotating PCB Clamp – The Professional Choice for Hands-Free Work

Adjustable Soldering Support Stand | 360° Rotating PCB Clamp – The Professional Choice for Hands-Free Work

Are you still frustrated by having to hold the board with one hand, dealing with wobbly alligator clips, or constantly flipping the board over to solder and having to reassemble it? The Baogong SN-390 Adjustable Soldering Support Stand is your ‘third hand’. Featuring an H-shaped metal base with thickened non-slip rubber pads, it sits on your workbench as securely as a small vice, ensuring absolutely no wobble during operation. With a maximum clamping width of 200mm, it can securely hold everything from the precision circuits of mobile phones and tablets to large computer motherboards.

Four core functions, designed specifically for soldering

4-in-1 multi-functional PCB clamping head: The SN-390 comes with four pre-set slot thicknesses—1.2mm, 1.8mm, 2.0mm and 3.0mm—covering everything from thin mobile phone boards to thick industrial multilayer boards. Need to change board thickness? Simply pull and insert for a quick switch—no need to hunt for shims.

360° Free Rotation + Thumb Screw Lock: The clamp can be rotated freely to any angle you require, allowing you to align with through-hole pads or solder the reverse side of double-sided boards without ever having to remove the board and re-clamp it. Once rotated into position, tighten the thumb screw to ensure it won’t shift, even under force.

Maximum 200mm clamping span + dual cross-slide metal bearings: The distance between the two clamps can be quickly adjusted from 0 to 200mm, whilst the slide bearings offer smooth operation and feature a built-in locking mechanism. It handles small modules with ease and has more than enough capacity for large motherboards.

Lightweight yet robust: The unit weighs just 450g and measures 30 × 16.5 × 12.5 cm, making it easy to slip into your toolkit. The metal base features a baked enamel finish to prevent rust, whilst the ABS arms balance strength with portability; shock-absorbing springs ensure the board remains steady during soldering.

Comprehensive coverage for your applications

Electronics repair shops: Repair mobile phones, tablets and control boards for household appliances – particularly when double-sided soldering or replacing power ICs is required – without needing someone to hold the board in place.

Product R&D soldering: Engineers can debug prototypes, make jumper connections and replace components; the stable clamping mechanism helps improve yield rates.

Maker DIY: Soldering robot control boards, drone flight controllers, and Raspberry Pi expansion boards – all manageable by a single person.

School Laboratories/Skills Training: Safe for students to use, preventing burns or short circuits caused by the board slipping.

Production Line Rework Stations: Significantly improves efficiency when securing PCBs in batches for component insertion or rework.

Why choose the SN-390 over ordinary alligator clips or plastic stands?

Ordinary alligator clips lack stability and can easily become misaligned if the soldering iron is pushed too hard; cheap plastic holders have a single clamping thickness and cannot hold slightly thicker boards. The SN-390, however, supports four thickness adjustments, features tool-free rotation and locking, and has a non-slip metal base that prevents wobbling—it is a fixture truly designed for professional repair and soldering.
