hello
is it ok to route 0.5mm tracks into 0603 resistor pads.?
Do you know what is the maximum track thickness that can be routed into 0603 resistor pads?
I am wondering if 0.5mm tracks will extract too much of the surface mount soldering heat out of the 0603 pads during the soldering process.?
A 0.5mm trace is ~20mils. An 0603 SMD is 30mils wide and I do use 20mil traces without issues.
Yes, it’s fine, and you can use a track that’s as thick as the pad if you like.
Assuming you’re mass producing the board, your CEM should profile it before committing to a large run. This process involves analysing the board layout and choosing a reflow profile accordingly. Normally it’s large components like big ICs which end up as the cold spots that need some extra heat.
If you’re soldering by hand then it’s a non-issue, just hold the soldering iron on the component a little longer until the solder starts to flow properly. You may possibly find components are a bit more difficult to remove should you need to - in which case two soldering irons are better than one!
