A carrier for holding a circuit board while passing round an automated insertion line has a rectangular frame with support members extending in from the inner periphery. In a particular example, the support members on three sides have support surfaces and lateral locating surfaces. Spring retaining members are provided, one above each support surface. On the fourth side, support members only have support surfaces in the example. At each end of the fourth side, a laterally deflectable cantilever spring member holds down the circuit board along the fourth side. An external flange provides a support for the carrier on a conveyor. The inner periphery is shaped to avoid interference with the solder wave and to avoid causing turbulence.
