Transistors
This kit comes with transistors
The body of the transistor is usually a small black
‘can’ with a flat on one side.
The shape on the PCB corresponds to the
‘can’
The transistor can be the one listed or any other suitable substitute with matching pin out. The
orientation of this part is crucial. The silkscreen layer indicates which way around it needs to be with
its transistor shaped outline, matching the transistors case. Solder this
very carefully.
The same warning about heat when soldering diodes also applies to transistors. Take your time
not to overheat.
The transistor in this kit is a voltage regulator.
IC’s aka ‘chips’
IC’s are small packages that contain many components. The ones that you will find in this kit will
have 8, or 16 legs.
On the PCB pin 1 will be marked with a * and there will be a small notch
drawn on the footprint. The solder pad for pin 1 will be square. The
socket will also have a notch. Be careful with the pins, they are fragile.
This is a socket. I do try to supply sockets for the chips, so unless I am
out of stock you should have one per chip. Solder these in place without
the chip, totally protecting the chip from heat. Please check you have all
pins through the pads before you begin soldering the socket.
