This page describes a PC board for a Surface Mount PIC12F629 with an In-Circuit Programming socket. For more on soldering and using prototype boards, see the article: Prototyping. For videos on soldering Surface Mount devices start HERE and see the site for lots more videos. The board contains a number of LEDs and components so a simple program can be produced and tested. You can add more components if required. The circuit to program the chip is shown below:
The programming socket is connected to 5 pins of the chip. Three pins, 2, 3 and 5 have been used as output pins for LEDs and a small piezo, for the experiments.
The photo below shows fine enamelled wire (0.2mm) connecting the programming pins to the chip.
The photo below shows the 5 pin socket mounted on the board and connected with very fine wire:
The connector between the PICkit2 and prototyping board.
Use 6 pins from a 0.1inch header strip, bent to 90°
after soldering to the matrix board.
