Build sequence
Soldering this board can be very complicated for some people since the solder pads are very close
together. Use a magnifying glass to make the job easier. The trick to soldering a PCB is to work from
small to big components. My building sequence suggestions in this section are based on the parts I
used myself. Sometimes some components are smaller (or bigger) so always use your own common
sense and change the order. Usually capacitors differ a lot in size depending on their rating.
Note:
Do not blow on your solder in an attempt to cool it down. That will possibly result in a bad join
that might corrode!
Start by soldering the resistors, then the diodes and then the ceramic capacitors.
If you want to
experiment with other transistors, lamps or LDR’s the
n you could socket them instead
of soldering them to the board. You’ll need a
some 20 SIL sockets, break off the sockets and solder
them to the board. Now is the time to solder these sockets on the PCB as well as the socket for the
IC.
Place the transistors, IC, LDR’s and lamp once you are finished with all soldering and off board
wiring!
If you are using small horizontal 6mm trim pots then solder them now (P1,P5 and P6).
Now continue by soldering small SMF capacitators (<1 uF), then the MKT capacitors then the 1uF
SMF and then the smaller electrolytes (<470uF). If you are using upright precision trim pots
(P1,P5,P6) then now is the time to solder them on the PCB. Finish by soldering the 470uF and then
the LM7815.
I suggest you now drill the holes in your enclosure so you can use it during the off board wiring.
Note:
Really take some time to determine where to place the pots, switches, jacks and PCB in the
enclosure before you start drilling. Measure twice, drill once.
You are almost ready to rock
, well… not really
. The difficult part starts now.
