Essemtec introduces simultaneous through-hole LEDs and SMD placement

Typically two different machines have been required for mixed placements ― an SMD pick-and-place and a placement machine for conventional components. With the CLM979 radial feeder, however, a pick-and-place can accomplish both through-hole LED assembly and SMD placement. This saves space, time and money.

The LEDs are supplied in radial tapes. The CLM979 feeder transports the components, releases them from the tape, cuts the wire ends to the desired length and aligns them parallel. So-prepared LEDs now can be handled by the SMD pick-and-place with a vacuum pickup tool.

In order to guarantee smooth insertion of the LEDs into the soldering holes, the wire ends are inspected by using optical systems (laser and vision). If the wires are out of tolerance, e.g. because of a bent terminals, the component is not placed but rejected.

The CLM979 feeder can be mounted in parallel to standard SMD component feeders. Therefore, mixed placement is possible in one run. Depending on the application, through-hole LEDs can be soldered using the solder wave or reflow soldering system (pin-in-paste technology).

The radial feeder CLM979 expands the application range of a standard SMD placement machine and increases the flexibility. The feeder is compatible with most of Essemtec’s automatic pick-and-place machines. It also can be retrofitted on machines of other brands.
