Board Routing and Layout

[ashley.hughes]

Hey all,

I am having trouble working out how the best way to approach laying out a components on a board and then the routing of the parts.

I use Eagle but the principles would be the same across most design packages I would think.

I am currently working on a LM317 board needs to be single sided as its going to be a test for a CNC milled board (Not ready for double side boards).



I knocked that up quickly. What is the approach you guys use in you layouts and routing

Thanks I knew there was a video out there some where. I will watch it when I have some spare time.

Got a exam to study for

Your 240R resistor wants to connect to the ADJ pin, not ground.

Just tiny note on one specific detail: when using trimmers or pots as adjustable resistors like R2 in this schematic, it is a good practice to connect the slider to one end of the resistor instead of leaving the end floating. Doing so guarantees that you will not get an open circuit if the slider should fail to make contact with the element inside for any reason. Some circuits really don't appreciate the connection breaking and this is an easy way to guard against that.

I have a real-time PCB layout video here.
Not a tutorial, but might be useful.
