+==== 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
+===== misc =====
+Use SMT footprints you can handle, e.g. 1206 for standard resistors and capacitors
