#103420 - I want the best money can buy, but do no Responding to: ???'s previous message |
I want the best money can buy, but do not want to pay for it.
Isn't that what this is about? I want 4 layer functionality from 2 layers! Keep also in mind, that doing the artwork for such a construction can be more expensive than using a multilayerboard from the start. (This is only true if artworker's salary is higher than manufacturing costs of multilayer.) I had a design where a lot of stuff and a common clock was to go on 2 small boards (total about 10 sq in) it cost me $5000+ for a professional layout of two 4 layer boards and I am glad I paid it. I realize that $5000 for a layout is beyond the possible for many jobs, but if it is so, then do not start the job. It serves no purpose to start a job requiring 4 layers and professional layout with a $100 budget in the "hope" that less will do. Erik |
