I'm making a two layer board for the first time, and have come across a question regarding component placement.
Say for example I have a through hole DC-DC converter. This converter has four pins and will be placed on the top of the board, therefore the soldering will be on the bottom layer.
My question specifically: Are the holes for the component plated and will there be solder points on both the top and bottom layer? Obviously I can only solder the bottom layer because the component will be covering the top, but can I route traces to the top of the holes still?
I've posted a photo of this specific problem. Am I allowed to route that top trace to the pin even though I will be soldering the bottom layer?
Thanks for any help!
