There is shown and described a workboard holder particularly adapted for maintaining flexible substrates in proper position during component assembly operations. In Fig. 1, a workboard holder is schematically shown. L-shaped frame member 2 is rigid, but sides 4 and 6 are resiliently connected to each other and to member 2. When sides 4 and 6 are pushed toward the center of the frame, the flexible circuit substrate is laid on top and stretched over hooks or bosses 8 to secure it to the frame. When the pressure on frame sides 4 and 6 is relaxed, sides 4 and 6 move away from the center, tensioning the flexible substrate material. The holder may then be conventionally conveyed through and past a series of process stations.
