I have maybe question because of my first PCB I soldered yesterday.
I used a 2x8 cm PCB, and this is the circuit I did:
A I J K L M N o-- -D1-—o--SW1--o---VCC o | D1 SW1 REL Ad 5V X---o D1 D2-SW1--o---CH1 o | D2 | REL X o R1 D2—-R2 R3 GND o R1 R2 R3 | X o R1 o R2 R3 o o R1 R2 R3 | Ad GND X---o R1 o R2 R3 o o | R1 R2 R3 | O-- -R1--o---R2--R3--o o
- A .. N are the columns of the PCB, I leave column B..H free for future additions (the VCC and GND lines are connected)
- Dx are diodes, Rx are resistors, SW1 is a pin header for a switch and column - Column N is a pin header for a relay (module).
- X are the connection 'terminals' of the PCB (on the left/right side, right side is unused)
However, during soldering, I noticed a few things and wonder what is best:
- I had a lot of soldering to do from one hole to an adjecent hole, and sometimes more like the connection between SW1, CH1 and R3 (colums K, L, M). Since I used just soldering, it was like a big 'solder blob' ... is it best to use some small wire instead? It will be very tiny wire(s)
- For the long VCC and GND lines I used a wire which I bent (see column A and the Xes) and soldered them on various places.
- I noticed it was very hard to solder adjecent lines (components close together), but leaving more space needs longer lines (and have to use wires instead of just solder?)
What are guidelines to make those 'interconnections' between adjecent holes?
And a side question: this is a 'double' sided board, but I don't see what it means, since the holes are connected anyway from the top and bottom side after soldering. Or do I miss something here?
There was a discussion about my 'ascii' notiation... I will explain it a bit below.
The problem is, that I never have soldered on a proto/pcb/stripboard whatsoever, only did breadboarding. Since I want to be sure I don't mix up lines/columns, I like to make it visible before I start (and to see it fits).
I will leave the ASCII text above, however, to make it clear, I thought it's better using Excel. I also spaced out the colums more, so it's easier to solder.
