What do you mean? nRF5x chips need SWD programmer attached to particular PINs. There exist sockets where you can program chips one by one before soldering on PCB but most of applications simply wire SWD pins to some header or test points and use some professional tool (like SEGGER J-Link/J-Flash or similar) to flash it in production. You can use SEGGER J-Link which is on-board of every nRF5x DK to program external nRF5x chips over P20 or P19 header.
