Today I have received TSEM R2 PCBs and a solder stencil from Elecrow.
I really like the white soldermask. I actually dont like the silkscreen lines that indicate component outline, I will remove those in a next revsion. I've put all components except the solar cells in the solder paste and used a hot air gun to reflow. The solar cells I soldered using the soldering iron, because they asre sensitive to excessive heat.
Then it was time for the first test and I measured that the 3.3V and the 1.8V outputs were working.
I am happy
