I've been tasked with minimizing cost of an existing design by taking it from a 2 layer board to a single layer board.
I've never made a single layer board so I am unfamiliar with pricing. I tried using Sunstone online quote to get an estimate for a 3"x2.5" single layer board with 15,000 units, but there doesn't seem to be a difference between 2 layer and single layer.
2 Layer estimate cost
Single Layer estimate cost
Both work out to being $2.10.
So it seems that I am missing something because the price did not change. Either I don't have enough volume, or this estimate tool is not that great at estimating.
Everything is on hold until Jan because of the holidays, but I was hoping to get a start on this during next week. But I want to know beforehand if my efforts are "worth" it.
Question: How much (approximately), can one expect to save by going from a 2 layer board, to a single layer board ? Assume board shape and size (3" x 2.5") stays the same and the same number of boards fit into a panel. Or is this insufficient information here and I would just have to wait until the New Year to speak with a fab house ?
