Don't think it has any thermal effect. It lowers manufacturing cost by
reducing the number of boards rejected due to uneven plating in holes.

Hi Lee,
I reviewed your interesting article entitled "Thieving in Printed Circuit
Boards", and have two question:
1. Does thieving has any effect on "thermal" performance of the board ?
2. Does it increase the PCB manufacturing cost?
Thank you in advance for your response.

I am often asked what the extra small dots are on the outer layers of many
dense PCBs. It is called thieving and I wrote an article explaining what
it is and why it is used. You can download a copy from our web site
