An apparatus used in a process for supporting a printed circuit board during a wave soldering operation including a frame with a frame opening in which a surface of the frame supports the board and also serves as a reference surface for vertically positioning the board above the solder pool. The board is secured against the reference surface with spring loaded clamps. Stiffeners preferably being an aluminum extrusion having a Tee or angle cross section is mounted along the outside edge of the reference surface of the frame and has a second reference surface facing in a direction opposite the reference surface of the frame. The second reference surface on the extrusion is accessible for support by a slide rail so that the height of the reference surface of the frame above the surface of the pool is independent of the thickness of the board or frame. A board support bar for minimizing warpage of the board from heat is disclosed as well as a hold down bar that secures components on the board so that they do not float away when contacted by the solder wave.
