DC to DC converter

Then 0.7mm or 0.6mm trace should be fine right?

[Martinn]

Just use a trace.
Width…? Difficult to judge from the image. You could probably calculate track resistance and compare it to the DC resistance of the inductor. If it’s a small enough fraction, should be OK.

Did you consider that the capacitance of the output capacitors is affected seriously at 12VDC due to the DC bias effect?

[NIL]

I did take that into account

That why 2 parallel capacitor on both end
But for out I think another one should give better margin

Guys the PCB seems to be completed fabrication and
pass electrical test too

[NIL]

Guys it’s here

[NIL]

Hmm here definitely something odd

How much space should be kept on here

Hmm here definitely something odd

Not sure what you are worried about, boards are not the best but look useable.

[NIL]

It sure is
What I am saying is that look at that input cap near VIN
can u see that one of cap pad is slightly out

I should have placed it carefully
