This year in lab_2 we will solder a USB-microcontroller board named bronze_v2. Bronze has includes Red/Green/Blue LED and LDR (=Light Dependent Resistor), and uses a USB host plug so you can plug it directly into a computer, or use a USB extension cable to put it somewhere else.
To assemble your bronze PCB you will arrange an appointment at the Institute of Neuroinformatics (http://www.ini.uzh.ch), which is located at UZH (Irchel or Milchbuck tram stop), building 55, floor G, electronics workshop, directions here.
Please follow the detailed steps below. Videos will help you see exactly how to do various steps.
Parts are kept in the ring folder in transparent envelopes. Each envelope is labeled with the bronze board part designator, e.g. R5, D1, etc.
Please put the parts back immediately after taking them out. And make sure that parts go back inside the labeled bag for each part!!!!!!!
Your setup for assembling SMD prototypes consists of
' and'rosin-core solder wire. Both are useful.
Before starting with this step, watch this video: http://youtu.be/4_XqoapZ5Qk to see in general how to solder small 2 pin parts.
In this video you the assembly and testing of some components on the bronze board which are simple to solder is shown.
On the bronze board, start with soldering the following
Your soldering should end up shiny and bright and should clearly flow up from the pad onto the pin of the part. The image below shows a resistor that was not soldered correctly. Do you see how the solder has not flowed up onto one pin of the resistor?
When you solder the USB connector:
A properly soldered USB header is next:
After all these components are soldered, the blue LED sh
