Homebrew PCBs

Use a mesh pattern, rather than solid. It happens because the electrostatic charge migrates from large areas.

Subject: [Homebrew_PCBs] ground planes
 

  
Does anyone have problems getting large ground plane areas to stay good 'n solid with copper?  I've been having a bit of problem with large ground plane areas using toner transfer method.  If I do a board without a large ground plane, the traces look good - trace size ranges from .015" to .050" or so.

I clean copper good, wash with alcohol.  Toner transfer at 360ºF with a laminator using Pulsar toner transfer paper, then etch in HCl and H2O2.  I used the green film last board and it seems a bit better, but not sure about large areas yet.

Just checking to see if anyone else has this problem, or maybe found a solution...... or maybe it's just me?

Thanks for any guidance and suggestions.
