Zhixin Heng Electronics - PCB Solution Design

Project name:
Contact / company:
Target date:

[Product]
1. What does the product do, and who is it for?
2. Prototype or production product? Expected annual volume?
3. Size constraints: length x width x thickness (mm)

[Electrical]
4. Main controller? (MCU / FPGA / SoC part number)
5. Main interfaces? (USB / CAN / RS485 / Ethernet / differential / RF)
6. Any high-speed interfaces? At what data rate?
7. Power: how many rails? Voltage / max current / ripple requirement?
8. Any isolation or withstand-voltage requirement? At what working voltage?
9. Analog measurement? What accuracy is required?

[Mechanical and process]
10. Board thickness? Copper weight? Layer count (any fixed requirement)?
11. Any relays, high-power devices or hard switches?
12. Component height limits? Two-sided assembly?
13. Surface finish requirement? Impedance test coupons?

[Production]
14. Where do you intend to run prototypes? Do you already have a fabricator (and their spec)?
15. Where does SMT assembly happen? Who buys and prepares the parts?
16. Required deliverables: Gerber / assembly files / BOM / 3D / source files - which ones?

[Constraints]
17. Cost ceiling?
18. Any obsolescence or shortage risks to avoid?
19. Certification needs (CE / FCC / medical / automotive)?
