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 5×7 led matrix arrays soldered in over the top of the text, others don’t and the text is visible instead)
