PCB update

21. May 2014 Zishen Hu Project Log (0)
I finalized the PCB schematic and layout. Some of components are custom libraries because I found the the physical circuit components  are too small to solder, I need to make the pads on the board bigger in oder to ease soldering process. The way I use to test if the physical circuit components fit the board is that I printed out a 1 by 1 scale board on regular printing paper, and then place the some components to check of accuracy of the custom libraries. This method allowed me to ensure the the size of the pads are right, and correctly spaced. More importantly, it saves our group not to place wrong order before it is too late.  I placed order at advanced circuit, one of the PCB manufacturers, hopefully the physical boards will ship no latter than week. The next goal is to solder all the components on the board and then perform thorough test for the circuit.
