Hey,
Is it normal to have a two layer PCB were some of the through hole pads are only on the bottom layer?
I ask because I'm designing a two layer board and for some of the through hole components pads i want copper to be only on the bottom layer (not the top).
Obviously with copper only on one side these pads cant be plated through.
In Altium if i change these pads from multilayer to bottomlayer it seems to do exactly what i want.
But my question is..
Is this normal?, do i need to make a point of telling PCB manufacturer about these pads being different or is it perfectly normal to have some pads like this on a two layer pcb?
The reason for wanting this is because the top layer has some large text printed on it. A few holes in the text will look fine but big shiny gold pads will ruin the text.
(The boards are duel use, some have 5x7 led matrix arrays soldered in over the top of the text, others don't and the text is visible instead)

The PCB manufacturer will certainly be able to plate through a hole with a pad on one side only. It's common practice for mounting parts like crystals which have metal bodies.
