Hi,
I would like itead studios to make a 2 layer pcb for me. I created a schematic in kicad and assigned footprints and drawn PCB using freerouter autorouter. It created 2 layers PCB. I would like to ask a question: If there is a track in top layer coming to particular throught hole pad and there is a track in bottom layer comming to tha same through hole pin - will i tead studio make a via in this pad (so the top ant bottom vias are connected)? Or will I have to make the vias which will connect top and bottom tracks manually?
And also a second newbie question - in which layer the through hole pads are situated? Let’s say I make only 1 layer pcb - then which layer are the pads situated in? Which layer should I use to connect the pads? Does it matter?
Hi,
if you have your PCB produced professionally it is safe to assume the holes will be plated and that the hole will effectively be a via.
Through hole pads are located on both Front and Back copper layers in a 2 layers board. On a 1 layer board it’s usually the back layer that is used to make the routing (and hence the pads). That is in order to have the components on the front side. When you layout your board you are actually looking at your board from the top. I says usually because if you use SMD parts you will probably use the front copper layer to make the routes as well.
And if you want to mix through hole and SMD parts on a single layer board you have to make the SMD part sit on the back layer (you can do that in kicad with the F key).
Maybe there are too many details in my answer, I hope it helps.
