Putting ICs into place
Before we attach the ICs we should remove the power supply again!
Maybe you must bend the legs of an IC
before it will fit into it's socket. When ICs are
coming from the factory, their leg rows often
are bent wider than the ordinary socket
demands.
If the IC's legs do not fit, one or more legs
could be bent completely crazy or break
apart while pressing the IC into it's socket!
To match the IC's legs with the socket's holes
we can do the following: we grab the IC with
both forefingers and thumbs from the top on
it's short sides. Then we press it on the table
with the complete leg row and bend the
whole leg row a bit inside by twisting the IC
carefully away from us. Try to not only bend the thin part of the leg, bend the WHOLE
leg which starts directly at the devices body.
Now we start by putting in place the smallest IC, the 8 pin optocoupler 6N137. You see
the small circular indetation on the top of it's body? This is where pin 1 is and this side
must be turned towards the notch of it's socket which is pointing to the right
(assuming your pcb lies in front of you, buttons in upper left corner). So we must turn
the 6N138 for the label to read upside down. Set it onto the socket, take care all legs
are gliding into the holes of the socket and gently press it down in it's socket.
