A PLCC device is suitable for use in surface-mount applications or may be installed in a PLCC socket. PLCC sockets may in turn be surface mounted, or use thru-hole technology. The motivation for a surface-mount PLCC socket would be when working with devices that cannot withstand the heat involved during the reflow

 process, or to allow for component replacement without reworking. Using a PLCC socket may be necessary in situations where the device requires stand-alone programming, such as some FLASH ROM devices. Some thru-hole sockets are designed for prototyping with wire wrap

ping.

The removal of components from a PLCC is traditionally accomplished using a specialised tool, the PLCC extractor, which hooks beneath the chip and lifts it out evenly.
