| Standard board:→Fusion PCB | Custom board:→Fusion Advanced PCB | |
| Why it is cheap/expensive | We will buy lots of metal-clad bade material in the same specification at once to reduce the cost. | We will buy many different kinds of metal-clad bade materials. |
| Put many designs from different customers in one huge panel to manufacture together. | Manufacture different design one by one. | |
| Using the standard and unchangeable processing line. | Change processing step when necessary. | |
| Advantage | Cheap and start from $4.9 | More customized options |
| Production will be fast by standard processing | high-end processing ability | |
| Disadvantage | No more options by standard processing | Expensive by customized the options and processing |
| Need to add a manufacturing number on PCB | Take more time to manufacture. | |
| What kind of people need it | Student, Engineers, Startup, Small enterprise, | Engineers, Purchaser/Buyer of enterprises, Researcher |
| What kind of product need it | Function test For fun Prototype or small batches during early trials |
the product for mainstream market the product with high integration design the product with high frequency signal the product cannot be finished with standard PCB |
| Seeed Production Code | The code MUST be printed on the boards | NO code printed on the boards |
