IC Package Substrate PCB: Precision Engineering for Mission-Critical Semiconductor Packaging

In the semiconductor world, there is zero margin for error. A substrate isn’t just a carrier; it is the electrical and thermal backbone of your silicon. If the substrate warps by even 20 microns during reflow, or if the impedance drifts by 7%, your entire batch is scrap.

We understand these stakes. At our facility, we don't just "make" IC substrates

Technical Domain & Capabilities

We focus on BT-based and ABF-build-up substrates, utilizing MSAP (Modified Semi-Additive Process) to push the limits of trace density.

Key Performance Metrics

Why Engineers Trust Our Shop

1. Eliminating the "Warpage Nightmare"

For ultrathin SiP and FCCSP substrates, warpage is the #1 cause of SMT assembly failure.

• Our Approach: We don't just use standard press cycles. We use compensated vacuum lamination and symmetric copper distribution analysis during the DFM stage.
• The Result: Our substrates maintain flatness through multiple 260°C lead-free reflow cycles, ensuring high-yield assembly for your flip-chip or wire-bonding processes.

2. Signal Integrity: Beyond the Data Sheet

A ±10% impedance tolerance is no longer enough for 5G or High-Speed Computing.

• Our Approach: By using MSAP technology instead of traditional subtractive etching, we achieve vertical trace sidewalls. This minimizes the "skin effect" and keeps impedance deviation within ±5%.
• Direct Evidence: Every batch is shipped with a TDR (Time Domain Reflectometry) test report confirming signal consistency across all critical nets.

3. Reliability Certified by Data, Not Just Promises

We operate an ISO Class 5 cleanroom because even a 5μm dust particle can cause a catastrophic short in a 20μm-pitch design.

• 100% AOI + AVI: Every single layer is scanned by Automated Optical Inspection (AOI), followed by Automated Visual Inspection (AVI) to eliminate human error in final QC.
• Traceability: Each panel is laser-marked with a unique ID, providing full traceability back to the raw material lot and the specific shift that processed it.

Field Case: 6-Layer HDI SiP for Wearable Tech

The Challenge:

A Tier-1 wearable brand needed to integrate a BT/BLE controller and 50+ components into a 12x12mm area. The design demanded a 0.22mm total thickness with 20μm traces. Most shops declined due to the extreme risk of "potato-chipping" (excessive warpage).

Our Execution:

1. Material Selection: Used ultra-thin HL832NS BT core for its low CTE (Coefficient of Thermal Expansion).
2. Process Innovation: Implemented a tension-controlled carrier system to prevent thin-core distortion during horizontal plating lines.
3. Validation: Conducted 1,000 hours of Unbiased HAST (130°C/85% RH) to prove long-term insulation resistance.

The Outcome:

The project moved from NPI to mass production in 22 days. Final assembly yield at the customer’s site stabilized at 99.5%, significantly reducing their total cost of ownership.
