🛠️ Application & Best Use Tips

• Choose SN‑390 if you want a lightweight, rotate‑friendly PCB vise for hobbyist soldering and rework.

• Go for a weighted alligator‑clip base unit for heavier or awkward boards needing sturdier support.

• Use multi‑arm gooseneck models when you need to position multiple parts (e.g., leads, wires) or want added accessories like magnifiers or iron holders.
