DOES IT ETCH
does it leave enough ink on the PCB to leave copper traces after etching?
Could you draw an 8 pin SMT landing pad with it?

I got a package of five "Sharpie Precision" precision markers from Staples.   Also marked "Ultra Fine".   The package contained two black markers.   The other ones were green, blue, and red.

The black marker draws a line 1/60 in. wide,, or 17 mil.

Heating season has begun, so today I started boiling water to add moisture to the air.

HTH,
