Thanks a lot. But any problem with T corner? Mounting holes for what? NTC thermistor will be attach to the heatsink directly.Comments:
The pads to the external world don't look evenly spaced. May not allow a connector to be used. The pads may be too small.
If this was a commercial board ans even if it wasn't, it's hard to tell which resistor is R5 and R6.
So, move the silk screen stuff a bit:
Center NTC with respect to R2
Move the labels R5 and R6 so you can tell which is which.
The BC557 is way out in right field.
Center R3 and R?
You can move the labels Q2 and TIP41C
I'd use a square PAD on one of the legs of C1 (I can't remember what the common convention is), probably negative. That's the striped side,
I think, "T" corners should be avoided. I think that's an etching issue.
If your etching this yourself, put some sort of label on the component side in copper, so you know what side is up. You don't want to etch a mirror image, Trust me.
One leg of R4 doesn't go anywhere?
Last, but not least. There are no mounting holes.
