I'm working on a new design (still laying out the components) and I have a chance here to reduce the size of the PCB by roughly 40%-50% if I use the other side for a QFP-100 IC (so it's heavy and will probably need gluing) and a few passives.
The PCB is 4 layers so savings are worth it, but I was wondering, if I used both sides and made the PCB smaller, how much extra will I pay for assembly? 2x? Will I be actually saving anything with those extra assembly costs, or might I end up paying more?
PS. I'm not sure I can get a quote right now, because I haven't finished the PCB yet, and they might need more info before they give me a quote, so I'd appreciate it if anyone with similar experience would share their thoughts with me, thanks.
