Custom HDI PCB Production Process :
1.Customer File Receipt & Review
Receive Gerber files, BOM, and technical requirements from customers, then conduct a comprehensive DFM (Design for Manufacturability) analysis to ensure manufacturability.
2.Quotation & Order Confirmation
Provide a detailed quotation based on layer count, materials, surface finish, precision, and order quantity. Confirm order details, lead time, and payment terms.
3.Material Preparation
Select and prepare high-quality base materials (FR‑4, high‑TG, high‑frequency, etc.), copper foils, and auxiliary materials according to customer specifications.
4.PCB Fabrication
Carry out inner-layer circuit imaging, etching, AOI inspection, and multilayer lamination. For HDI boards, include laser drilling, microvia formation, and sequential lamination.
5.Plating & Surface Treatment
Perform hole metallization, electroplating, and selected surface finishes such as ENIG, immersion gold, HASL, OSP, or hard gold.
6.Precision Machining
Conduct routing, drilling, gold finger beveling, and silk-screen printing according to custom dimensions and design requirements.
7.Electrical & Performance Testing
Implement electrical testing, impedance testing, high-voltage testing, and reliability inspection to ensure compliance with IPC standards.
8.PCB Assembly (Optional)
Provide one-stop SMT/DIP assembly, component soldering, BOM sourcing, and finished product functional testing.
9.Final Inspection & Packaging
Conduct final visual and quality inspection before vacuum packaging to avoid damage during transportation.
10.Shipment & After-Sales Support
Arrange delivery according to customer requirements and provide after-sales technical support and file archiving.
