This post is a series from my the previous post about my PCB order at pcbway.com. Please check the details on their websites PCBway
The PCB that I ordered from PCB Way is actually consisting of main board for PCM58 DAC with an op-amp output per channel for IV conversion and low-pass filter. This DAC is in non-oversampling and using shift-register for I2s input. The I2s input is chosen because it is more flexible for me to put the digital input module, either USB or SPDIF input, as long as the output from receiver module is I2s.
The other PCB is for the power supply board. This power supply is consist of rectifier and capacitors, then goes to DC regulator using 2 pair of LM317 and LM337.
Now let's see how good is the PCB quality ordered from PCB Way and how easy to soldering the pads with the components installed on it.
