Using this PCB magnetic soldering holder set is a breeze. First, decide whether you want to hold the board by the point or use the groove to clamp it. Place the board on the stainless - steel platform. The pins with magnets at the bottom will firmly hold the board in place. When soldering, make sure the board is properly aligned. As for maintenance, keep the platform clean. Wipe it with a dry cloth after use to prevent dust and debris from accumulating. Avoid dropping the set as it may damage the magnets or the platform. If the pins get loose, you can try gently pressing them back onto the platform to ensure they are firmly attached.
