First go at PCB manufacturing: a break-out board for the Analog Devices ADXL190 ±100g MEMS accelerometer. It's packaged in a slightly uncommon SMD SO-14W ceramic body. For easier prototyping I wanted to have more accessible 2.54mm grid pins, so this was the perfect project to give PCB making a first try.

The PCBs were designed with the Eagle PCB layout tool, transferred to copper using the laser toner method, and etched with a solution of sodium persulfate. The whole process took about two hours, the better part of which was spent on the layout.
