+==== 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).
+Große Nieten (Innendurchmesser = 1 mm):
+Passendes Via:
+Bohrung (= Bohrlochdurchmesser): 1,5 mm
+Durchmesser (= Außendurchmesser): 2,5 mm
+Kleine Nieten (Innendurchmesser = 0,6 mm):
+Passendes Via:
+Bohrung (= Bohrlochdurchmesser): 0,9 mm
+Durchmesser (= Außendurchmesser): 1,5 mm
+Through-hole (THT) components need to be routed to at the bottom layer.
+===== Common mistakes =====
+Trust in autorouter
+Wrong track size
+Use of discontinued or unavailable components
+No prototyping/simulation
