| We are a medium sized PCB assy. house manufacturing about 2000 motherboards a day. There is a major problem we are facing at the wave soldering stage, i.e. warpage of the PCB. As soon as the PCB touches the wave it warps severely from the centre

Is this a single sided or double sided board? We run the first side flat on the oven belt this keeps the board flat for the second side assembly. If the board warps during the second reflow process we will make a support fixture to carry the PCBA
