Considerations for PCB design thickness:
Evaluate PCB thickness in many aspects
1. Process capacity of PCB Factory
Consider whether the board factory has equipment to manufacture the required circuit board thickness, make it as soon as possible in the design process, and consider the design requirements of relevant DFM. Otherwise, you may be forced to modify and redesign the PCB stack structure.
2. Extension of delivery time
The selection of board factory is not a standing material, which will prolong the production cycle of PCB. Therefore, for non-standard board thickness, the delivery time needs to be considered.
3. Additional costs
The cost of special plates, additional manufacturing costs and extended delivery time costs need to be evaluated to determine whether the additional costs are acceptable. Adopting standard PCB thickness first will make manufacturing faster and lower cost. However, if you decide to select non-standard thickness, you should communicate with the board factory before starting PCB design to ensure that the process of the board factory can be manufactured, and communicate the delivery time and additional manufacturing costs.
Of course, the conventional thickness of the general finished PCB is 0.8mm to 1.6 Mm, and the more common plate thickness specification is 1.6 mm in metric unit by default (about 63mil in British unit). Many connector standards are also adapted according to 1.6mm specification.
