Save PCB manufacturing cost at design stage

PCB manufacturing costs depend on many factors that should be taken into consideration while you are designing your product. If you’re a newbie to PCB design then your design might not be cost optimized. Here are some design considerations that will help reduce the price of your PCBs:
1. Minimize your board layers
Adding additional layers can be useful if you need additional routing space, need power and ground supply planes, need to control trace impedance, or need low noise performance. A four layer board will cost you roughly twice the amount of a two layer board, so if you are very cost sensitive then this is something to keep in mind.
2. Skip the through-holes
Through-hole mounting is often beneficial because it provides stronger mechanical bonds, but unless you are building something complex, it is usually better to stick to surface mounting. This is because the drilling required for through hole results in more expensive board and limits the total area of the PCB for routing signals. This becomes more of an issue with multilayer boards since the holes pass through all layers of the board. Through-hole components require a setup separate from SMT placement which also significantly increases the assembly cost of a board.
If you do need to use through holes, try to use the biggest diameter possible for the holes since smaller holes require more precise machinery which increases cost. You can refer to this Multi-factory Compatible Drill Table to help you determine what size hole you should draw.
3. Use green soldermask
Green is the industry standard for solder mask color. Although making your PCB a different color will definitely make it unique, it will require additional process time due to cleaning and changeover which you will have to pay for.
4. Minimize board size
This is pretty obvious, but the bigger the board, the bigger the price, PCB manufacturers need more material for big PCBs. Keep your boards as small as possible to keep the cost down.
5. Avoid irregular shapes
Some PCB fabs charge extra for irregular shapes. When you panelize a PCB, all the material not used around it is considered waste material which you also sometimes have to pay for. Try to use standard shapes like squares and rectangles Also try to avoid internal cutouts unless completely necessary. It will add difficulty to profiles achievement.
6. Time is of the essence
A large majority of the cost of PCB and assembly is simply determined by time. Anything that requires the PCB or assembly house to spend extra time on your project
The PCB manufacturing process is an essential element of the electronics production lifecycle. PCB manufacturing employs many new areas of technology and this has enabled significant improvements to be made both in the reduction of sizes of components and tracks used, and in the reliability of the boards. To know to save PCB prototyping costs is essential to production developing.
