Specialized Mechanical PCB Processes for Complex Applications
We excel in advanced mechanical PCB processes that require extreme precision. These specialized processes are used for custom designs that push the limits of traditional PCB manufacturing.
- Metal Blind Slot / Metal Cavity PCB: Metal-based PCBs (aluminum or copper) with non-through slots or cavities accommodate high-component placement, improve heat dissipation, and help reduce overall board weight.
- Step-Down Cavity PCB: Multi-level cavities expose inner layers for fine-pitch wire bonding in LED and RF assemblies, ensuring precise signal routing for performance-critical hardware.
- Backdrilled PCB (Stub Removal): Removes non-functional via stubs to avoid signal reflections and preserve integrity in designs running 25 Gbps and beyond.
- Controlled Depth Drilling / Routing: Allows partial-depth drilling for press-fit connectors, mechanical fixtures, or selective rout-outs without breaching the full stackup.
- Castellated Hole / Half-Cut Via: Edge-mounted half vias enable modular soldering for daughter boards and wireless modules.
- Edge Plating / Side-Wetted PCB: Metallized board edges add EMI shielding and robust grounding for high-frequency or power electronics.
Advanced Thermal Management Solutions for High-Power Devices
Effective thermal management is a cornerstone of reliable PCB designs for high-power applications. At APTPCB, we employ several advanced techniques to efficiently manage heat dissipation in high-power and high-frequency systems.
- Embedded Copper Coin (I/T/U-Type): Integrates copper coins directly under heat sources for LED modules, IGBTs, and GaN devices.
- Heavy Copper PCB: Thick copper (3 oz – 10 oz) handles high current without overheating, perfect for automotive and industrial drives.
- Pedestal MCPCB: Copper columns isolate hot components, accelerating heat flow in dense lighting or power assemblies.
- Extreme Heavy Copper / Busbar PCB: Up to 30 oz copper for power distribution and busbar-like conductivity on-board.
- Copper-Invar-Copper (CIC) PCB: Ultra-low CTE stacks for aerospace and defense applications demanding dimensional stability.
High-Density Interconnect (HDI) and Microvia Solutions
HDI technology is essential for compact and high-performance PCBs, especially for devices requiring small form factors and high-speed connections. Our microvia and stacked via technologies enable efficient signal routing and enhanced electrical performance.
- Any-Layer HDI (ELIC): Every layer is laser-drilled for maximum routing density without traditional through-vias.
- Stacked Microvia PCB: Vertically aligned microvias power ultra-compact designs such as smartphones or GPUs.
- Skip Via HDI: Connects non-adjacent layers to minimize total stack height and trace lengths.
- Deep Microvia: Multi-dielectric laser drilling delivers high aspect ratios with clean copper walls.
- Via-in-Pad Plated Over (VIPPO): Resin-filled, plated vias embedded within BGA pads support fine-pitch assembly.

Rigid-Flex PCB Design for Compact Applications
Rigid-flex PCBs combine the benefits of both rigid and flexible circuits, allowing for compact, flexible designs in space-constrained applications like wearables, medical devices, and automotive electronics.
- Bookbinder Rigid-Flex: Independent flex arms support repeated 180° bends without stressing rigid sections.
- Flying Tail / Finger Flex: Multiple flexible tails extend from rigid cores for unconventional connector geometries.
- Air-Gap Rigid-Flex: Separates flex layers to improve bend reliability and electrical isolation.
- Sculptured Flex: Selectively thickened copper conductors boost mechanical strength in ultra-thin flex zones.
High-Frequency and Microwave PCB Solutions
Our RF and microwave PCBs are designed for high-frequency applications that require precise control over signal integrity and low-loss transmission lines. We use advanced materials and techniques to ensure reliable performance in demanding RF environments.
- Hybrid Stack-up (FR4 + Rogers/Taconic): Blends cost-effective FR4 with premium RF laminates for tuned impedance.
- Fusion Bonding PCB (PTFE Fusion): Uses PTFE fusion to eliminate prepreg seams in ultra-high frequency builds.
- Patch Antenna PCB: Tight control of copper roughness and dielectric height for efficient radiators.
- Cavity Filter PCB: Precision milling plus RF line design yields compact, high-Q filters.
- Metal-Backed PTFE: PTFE bonded to metal cores enhances thermal spread and mechanical rigidity.

Frequently Asked Questions
Answers to the questions we hear most from hardware teams.
When should I use advanced stackups instead of standard builds?
Choose advanced when you need HDI, blind/buried vias, mixed dielectrics, or tight impedance and loss budgets beyond standard 1-n-1 builds.
Do you support hybrid materials?
Yes—low-loss cores with FR-4 builds are supported; we align press cycles and resin content and will flag incompatible Tg/CTE pairs.
What impedance data do you provide?
We share field-solver targets, stackup cards, test coupon results, and TDR data on request.
How are via structures qualified?
Microvias, stacked vias, and backdrills follow coupon testing, IST or cross-sections, and IPC-6012/6018 inspection.
Can you advise DFM before release?
Yes—send Gerber/ODB++ and impedance goals; we return stackup, via options, and manufacturability risks.
