+ | ==== Design considerations for self-etched PCBs at the university ==== | ||
+ | The biggest PCB blanks we stock at the university are 160 mm by 100 mm. Your designs should not be bigger than that. | ||
Available sizes for punching vias in the university: 0.6 mm (drill 0.9 mm, pad 1.5 mm) and 1.0 mm (drill 1.5 mm, pad 2.5 mm). | Available sizes for punching vias in the university: 0.6 mm (drill 0.9 mm, pad 1.5 mm) and 1.0 mm (drill 1.5 mm, pad 2.5 mm). | ||
