Occasionally boards can not be reprogrammed on site to the customers needs, in these instances it is often necessary to reprogram and replace a component known as the IC chip, this can be a little bit complicated so we here are some instructions,specifically for the SP100 Coin Meter but still fairly general, on IC removal.

These instructions only contain simple, other methods exist however they require specialist tools which is avaible  should be used.

Using a flat-headed screwdriver gently ease up one end of the chip by a small amount, to do this slide the screw driver in by a small amount the rock it from side to side.

Gently repeat on the opposite end of the IC chip with out raising the end of the IC chip too much as this will push the first end back in.

Grasp the chip at both ends and pull firmly upward, if the chip does not come out easily repeat the earlier steps and try again. Be sure to pull the chip straight up with only gentle rocking to ease it out, the pins bend easily and are delicate.

When replacing the chip firstly make sure it is the correct way around, both the chip and the socket have semi circle cuts out which need to be aligned. Then place the chip onto it’s socket and firmly push down. If the pins are not aligned with the socket and are two wide then place the chip side-on a flat surface and then slowly “roll” the chip to bend half the pins at once.

All chips have a semi circular cut out to denote the top, visible in the above picture on the left, this lines up with the semi-circle cut out on the socket and the makings on the board.

Showing the orientation of the IC socket on the SP100, the semi-circle cut out is visible on the left again.
