How do you reduce the cost of your board and make the PCB fabrication and assembly process painless?
The answer is ensuring manufacturability through design for manufacturability (DFM). DFM set design guidelines that take into account the processes and capabilities of the manufacturing industry.

Designing your boards without preliminary discussion of what you're trying to accomplish with your PCB supplier.
There are so many different PCB materials available today that some of them are not readily available and others are more available. Flex, high speed, RF, high temp & RoHS boards can all have different materials and each material can be made by a different manufacturer with slightly different specifications. Lead time on some special materials can be several weeks. You will want to choose the material that fits your needs more closely and is more available.
Designing your boards without detailed stack up information from fabricators.
Every manufacturing facility has different manufacturing tolerances that can affect the target impedance and/or stack up. When you design your board without consulting with your PCB suppliers, adjustments may need to be made in order to certify your impedance requirements. This may increase the lead time and the cost, if special order material is necessary to make the adjustments. Have the stack up provided by your PCB suppliers before proceeding with your design.
Setting up the plane layers with the same requirements as signal layers.
This can add unnecessary difficulty to your printed circuit board and cause potential yield issues, increasing the cost of the boards as a result.
Your data package does not include an IPC-356A net list.
The IPC-356A net list allows your PCB supplier to find errors in the PCB design by comparing the gerbers to the CAD database. It's possible that the files contained errors or were corrupted when exported. Without this net list, many of the errors cannot be caught.
