+ATTENTION! If you want to have your PCB produced at HSRW, it is really important that you have read and understood the following in order to avoid problems later on!
+Design Rules For Etching At HSRW
+=>PCB dimensions:
+    -Max. 100 x 160 mm
+=>Minimum Feature Sizes
+   ->Copper features & Trace Width
+     -Recommended: 0.6mm
+     -Minimum: 0.4mm
+    ->Distance Copper/Copper (Isolation distances)
+      -Recommended: 0.6mm
+      -Minimum: 0.4mm
+    ->Available Via Sizes
+      -Small (Via 0.6mm, Pad 1.5mm, drill 0.9mm);
+      -Large (Via 1mm, Pad 2.5mm, drill 1.5mm)
+=>Other Important Things
+      -Through hole parts located on the top have to be connected on the bottom layer
+      -Through hole parts located on the bottom layer have to be connected from the top
+      -You may otherwise be unable to solder your parts properly!
+WARNING: Not following these rules is risky and may often lead to a defective PCB!
