The influence factors of PCB price
The PCB cost calculation of each factory is not the same, there is a simple method (length*width= square unit price), but also a complex method (according to the process requirements, quality requirements, etc.)
There are a few specific factors that have been described earlier, In short, there are the following points,
PCB Base Material (normal FR4, Rogers, PTFE)
1.Material: FR-4, this is our common double-sided and multi-layer material.And FR-1,CEM-1 these are our common single-side board material, and the price of these materials are big different than the above two-sided, multi-layer board. And It’s not often used today.
2.The PCB thickness, our common thickness is: 0.4,0.6,0.8,1.0,1.2,1.5,1.6,2.0,2.4,3.0,3.4, and the price difference of our regular board thickness is not very large.3.Copper foil thickness ,copper thickness is generally divided into: 2/1oz (1OZ) (2OZ), (3OZ), 140 (4OZ) and so on.
4.The raw material supplier, what’s commonly used are: ShengYi ,Kingboard, GDM and so on
PCB Process Cost
1. Such as detailed and dense circuits2. If there's a BGA on the board
3. Surface Treatment Technology( Immersion gold, lead free HASL, OSP, etc)
4. Process standards：IPC2 IPC3
5. Stamping Mold
6. Tolerance, high aspect ratio
7. Special requirements
