The invention relates to the field of manufacturing of electronic component integrated boards, in particular to a movable PCB (printed circuit board) welding seat. The movable PCB welding seat comprises a base table, a support table and a clamping structure, wherein the base table is of a square iron table structure, the geometric center of the base table is fixedly provided with a cylindrical shaft, pin posts are arranged on the cylindrical shaft, each pin post is horizontally embedded into the cylindrical shaft through a spring, a rotating shaft is fixedly arranged under the support table, a V-shaped clamp groove is formed inside the rotating shaft, each pin post is clamped in the V-shaped camp groove, a rotating handle is fixedly arranged outside the rotating shaft, the clamping structure is arranged at two sides of the support table, and comprises a clamp table and a spring press sheet, a cam rotating rod is arranged in the clamp table arranged at two sides, a gear groove matched with the cam rotating rod is formed in the clamp table, and one end of the spring press sheet is fixedly arranged on the cam rotating rod. The movable PCB welding seat has the beneficial effects that according to the PCB welding seat adopting the scheme, the direction of the support table can be manually changed, each side of a PCB can be favorably welded, in addition, the structure is simple, the operation is convenient, and the work efficiency of PCB welding is favorably improved.
