Core Manufacturing Strengths
1. IPC Class 3 Reliability & "No-Repair" Policy
In accordance with IPC Class 3 requirements for high-performance electronics, we strictly enforce a Zero-Repair policy. Any board that does not meet the initial fabrication criteria is rejected to ensure maximum field reliability. We provide a full IPC Class 3 Compatibility Report with every delivery.
2. Advanced Via-in-Pad (IPC-4761 Type VII)
Our facility utilizes state-of-the-art non-conductive via filling and metallized capping. This process ensures a perfectly flat pad surface, which is critical for high-density BGA mounting and superior thermal management.
3. Complex Blind Via Management
Our engineering team is expert at managing intricate drill pairs as defined in .GD1, .GD2, and .GD3 layers. We ensure precise registration (within .002 inch) for:
L1-L2 Blind Vias
L13-L14 Blind Vias
Full Stack Thru-vias
4. Specialized Edge Plating
We offer precision Edge Plating on specific sections (as per .GM3 layer) while maintaining strict clearances for center conductors and gap areas. This provides optimal grounding and EMI protection for sensitive high-frequency designs.
Engineering Consultant Services (DFM Support)
We go beyond simple fabrication. For high-layer counts, we provide professional DFM (Design for Manufacturing) advice, including:
Bond Enhancement Treatment: Optimization of chemical/mechanical treatments to maximize interlayer adhesion.
Foil Profile Selection: Expert guidance on selecting the right copper foil profile to balance signal integrity (Low-loss) and peel strength.
Quality Assurance & Compliance
100% Netlist Testing: Applied IAW IPC-9252 to ensure circuit continuity.
Solderability: Guaranteed IAW J-STD-003, Class 3, Category 2.
Flatness Control: Maximum allowable warpage and twist is strictly limited to 0.75% or less.
Traceability: Full Certificate of Compliance (CoC) provided.
Target Applications
Aerospace & Defense: Flight control systems and avionics.
Medical Technology: Life-support systems and high-resolution imaging.
Telecommunications: High-speed routers and switching equipment.
Industrial Automation: Precision robotics and control modules.
