well, if you say the pads are OK we simply disagree:

however these here:

are more what i like...

I have no problem with disagreeing with you, but in the first picture
the remaining ring is thinner than the track itself. that simply can't be
good and
i do not think a decent soldering joint will result from it.

I had similar pads to the ones you have there, years ago, until i made
them bigger
and the overall quality did go up dramatically.

You can make a working circuit by just ending the track straight, and
drilling a hole
at the end. then you simply "glue" the part to the track. if you like it,
well...

However i do not recommend it for a beginner already having problems with
hitting the center
of the pad.

It would not at all be a problem to make bigger pads on the pictures you
have there, but
hey, i do not want to tell you what to do... if you like it then stay with
it.

I just want to help..

Only keep in mind the difference when you have throughhole plating, it is
riveted
together, which it isn't with our boards.
