[PCB_FORUM] Re: How long it takes to route a board?

Cristian,
      This is a very complex question. Some have come up with formulas. 
 Variables include:
      pin count
      complexity/rules
      library creation required
      availability of Specctra (and fast enough computer)
      availability of template design 
      
      Others will print out the schematic, heft it, and guess. Dartboards 
probably also come in handy.
      
       I agree with Gary. Personally, I break it down to tasks and estimate 
each. If you're only routing, then you have only a few variables. If you're 
working from scratch, then use a spreadsheet.

        Hello,
        
        I'd like to identify the best method to estimate how long it takes to 
do board design and how much to charge the customer. So I would like to hear 
different opinions on this topic.
        When your boss/customer asks you how long it will take to you to do the 
PCB design, how do you evaluate that?
        
        Thanks,
        
        Cristian
