1. Industrial PCB Production Process
Industrial PCB production involves multiple precision manufacturing stages, each critical to achieving the final board performance. From initial material selection through final electrical testing, every step follows documented IPC standards that ensure repeatability and quality. Understanding these stages helps procurement managers specify requirements accurately and engineering teams design for manufacturability.

| 1. Design & DFM | Design for Manufacturability review | Trace clearances, drill aspect ratio, impedance |
| 2. Material Prep | Core lamination, cutting to panel size | FR-4, high-Tg, Rogers materials available |
| 3. Drilling | CNC or laser drilling of via holes | Min 0.25 mm mechanical, 0.10 mm laser microvia |
| 4. Plating | Electroless copper + pattern plating | 18-25 µm copper thickness in barrels |
| 5. Imaging | Dry film or LDI exposure | 2-6 mil line resolution |
| 6. Etching | Chemical copper removal | ±10% line width tolerance |
| 7. Solder Mask | LPI or photoimageable mask | Green, red, blue, black, white colors |
| 8. Surface Finish | HASL, ENIG, OSP, Immersion tin/silver | ENIG: Ni 3-6 µm, Au 0.05-0.15 µm |
| 9. Silkscreen | Legend printing for component placement | White ink on board surface |
| 10. Testing | AOI + flying probe or ICT | 100% electrical test per IPC-9252 |

6. Frequently Asked Questions
What files do I need to provide for a quote?
Provide Gerber files (RS-274X or Gerber X2 format, preferred), drill file (Excellon format), and a stack-up specification or layer count. If you do not have a stack-up, our engineers will design one based on your application requirements at no extra charge.
What is the minimum order quantity (MOQ)?
We accept orders from 5 pieces for standard prototypes. Volume pricing starts at 50 pieces; mass production pricing at 100+ pieces. There is no MOQ for standard samples — even a quantity of 1 is accepted for prototype builds (at standard sample pricing).
Can I get IPC Class 3 certification?
Yes. Specify IPC Class 3 at order placement. We perform micro-section analysis on a representative sample from each production panel and include the micrograph report with your shipment. Additional charges apply for Class 3 inspection and documentation.
Do you offer PCB assembly (PCBA) services?
Yes. We offer full turnkey PCB assembly with component sourcing from our global distributor network (Digi-Key, Mouser, Arrow). We also support consigned assembly if you prefer to supply your own components.
What does your free DFM review cover?
Our engineering team reviews every order before production begins. DFM review covers: trace/space clearances, drill aspect ratios, solder mask dams, silkscreen legibility, panelization layout, and impedance calculations — all at no charge.
How do you handle quality disputes?
We review all defect claims within 24 hours of receipt. If the defect is traced to our manufacturing process, we cover full rework and return shipping at no charge. We maintain a documented defect rate log.
