TDA2030A Audio Amplifier Kit PCB

The TDA2030A stereo audio amplifier printed circuit board (PCB) has very clear markings for the component placement. The silk screening is clear, and the solder mask is accurate. The only down side with this circuit board was that the copper pads did not have a HAL tin layer.

Trace Side

Without tinning on the copper traces, it is very difficult to solder directly on the copper pads. The pads required cleaning of oxide, and the heat had to be minimal, otherwise the pads will detach. I used Omega solder, which is lead-free and rosin-free and worked very well.

Copper Pads

Some tinning on the copper would have been nicer to reinforce the copper pads.
