A Cold Solder

Warmup

In the warmup the image showed a solder bridge. A solder bridge can make the circuit unable to function or in a more dangerous case may set on fire. To remove the bridge you must use a special type of tape.

Project Overview

In this project we learned the basics of soldering and soldered together LED Glasses. The purpose of the project was to teach us more about soldering and how to be careful and exact when doing so. The Glasses where assigned to us for having simple instructions while also being a bit of a challenge with several components having polarity and one wrongly placed componet might have you restart.

Soldering Process

In the first step we soldered the mega ohm resistor into the board, simple step no polarity involved. In the Second Step I added 3 10k ohm resistors, another simple step, no polarity involved and it showed on the board where to place them.

In step 3 I added 3 1K ohm resistors, this step was a bit trickier than the ones before it because they where right next to one another. In step 4 the microphone was soldered on, no problem just had to check the polarity.

Step 5 was the most difficult task. In this step I had to solder 50 LEDs. This did take a while and I always had to check polarity on them before I put them in. The difficulty was doing the same thing over and over again though. In Step 6 the Ceramic Capacitator was soldered on, no struggle since their was no polarity in it.

In Step 7 the LED driver was added. This was a really important step since it had polarity and if I messed up Ide have to restart. Thankfully I got it in the right way. In Step 8 the transitor was added, their was the slight issue that it had 3 prongs instead of the common two through out the project.

In Step 9 the Capacitators were soldered on, slight issue in the polarity but nothing else. In step 10 the potentiometer was soldered on. It was hard to tell when it was the way into it but eventually it worked.

In Step 11 the switch was added, it was a bit difficult soldering the opposite the other way than the other components but not to much of a challenge. In step 12 the positive metal sheets were added, the only issue was figuring out how to place them onto the circuit board.

In step 13 the negative metal sheets where soldered onto the edges. This step was easier than step 12 in that the places to place the sheets was already decided. In step 14 I placed the board into the plastic glasses case. It was a bit difficult but once inside it was fine.

In step 15 the screws where screwed into the board into the case. This was a difficult because the board was sticking out a bit so I had to press down on it to screw the screws in. In step 16

Problems Encountered

While no problems occured during the soldering process I did have one issue. The 50 LEDs I had to solder on. This took over two days of work. It wasnt difficult, it was just difficult. In the end though I was able to solder all of them on with out any difficulties.
