 ## Assembly tips
 
@@ -52,6 +50,9 @@ Once the PCB is milled or etched make sure you clean the 180V rails thoroughly,
 that voltage is high enough to cross gaps of 0.1mm.
 Once that happens it burns a thick dark trace into the fiberglass of PCB and
 it's pretty tricky to clean up.
+The PCB is designed with 0.4mm clearance to be compliant with HV designs.
+This clearance of course assumes that PCB traces are covered.
+Either use solder mask or conformal coating.
 
 Use the bench power supply to gradually power up the device,
