At APTPCB, we are committed to delivering the most advanced and precise PCB manufacturing solutions, specializing in high-performance designs and complex applications. Our cutting-edge processes cater to industries ranging from consumer electronics to aerospace, enabling efficient production and exceptional quality. With expertise in thermal management, rigid-flex technology, microvia solutions, and more, we ensure that every PCB meets the highest standards of precision and reliability.

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: We manufacture metal-based PCBs (aluminum or copper) with non-through slots or cavities designed to accommodate high-component placement, improve heat dissipation, and reduce the weight of the PCB.
• Step-Down Cavity PCB: Multi-level step cavities are created for wire bonding, exposing internal layers for fine-pitch wire bonding in LED and RF components. This is critical in high-performance applications where precise signal routing is necessary.
• Backdrilled PCB (Stub Removal): Backdrilling removes non-functional portions of through holes (called stubs) to eliminate signal reflection and improve signal integrity, especially in high-speed designs (e.g., 25Gbps+), ensuring reduced signal degradation.
• Controlled Depth Drilling / Routing: This process allows drilling to specific depths without penetrating the entire PCB. It is used for applications that require press-fit connectors, pin holes, or mechanical fixtures in complex designs.
• Castellated Hole / Half-Cut Via: Half-cut vias along the PCB’s edges allow for modular soldering, often used in module-on-board designs, providing easy edge-mounting of components.
• Edge Plating / Side-Wetted PCB: We can metalize the sides of the PCB for EMI shielding and grounding, enhancing the board's performance in sensitive applications, such as high-frequency circuits or power electronics.

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-Type, T-Type, U-Type): We embed copper coins in the PCB, providing high-efficiency thermal conduction to manage heat in high-power applications, including LED modules, IGBTs, and GaN devices.
• Heavy Copper PCB: Copper thickness is increased from 3oz to 10oz to handle high-current applications without thermal issues, making these PCBs ideal for power electronics and automotive systems.
• Pedestal MCPCB: Metal Core PCBs with copper columns provide effective thermal separation between components, ensuring efficient heat dissipation and improving the thermal management of LED and high-power modules.
• Extreme Heavy Copper / Busbar PCB: We can manufacture extreme heavy copper PCBs (up to 30oz or more) to support high-current transmission. This technology is ideal for power distribution and high-current applications.
• Copper-Invar-Copper (CIC) PCB: Using a combination of copper and Invar materials, these boards offer ultra-low thermal expansion, ensuring precise thermal management for aerospace and military applications where extreme precision is required.

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): In this design, every layer is interconnected through laser microvias, creating high-density interconnects with no traditional through holes, ideal for multi-layer, high-performance PCBs.
• Stacked Microvia PCB: Microvias are stacked vertically (not staggered), ensuring the high-density interconnections necessary for compact designs in smartphones, tablets, and high-end graphics cards.
• Skip Via HDI: This design skips intermediate layers to connect non-adjacent layers, allowing for reduced layer counts and optimized signal routing, ideal for multi-layer designs that require compactness.
• Deep Microvia: We offer deep microvias that can drill through multiple dielectric layers, achieving high aspect ratios and enabling more complex designs with improved signal integrity.
• Via-in-Pad Plated Over (VIPPO): We provide via-in-pad technology where vias are embedded in the BGA pads, filled with resin, and plated to ensure a smooth, flat surface ideal for fine-pitch BGA assembly.

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: These boards allow for 180-degree bends in compact devices, with flexible areas designed to move independently from the rigid part of the board, providing excellent dynamic flexibility.
• Flying Tail / Finger Flex: The design features multiple flexible tails that extend from the rigid PCB sections, creating a highly flexible connection in applications where traditional rigid PCB structures cannot be used.
• Air-Gap Rigid-Flex: This design keeps the flexible layers separate from each other, creating air gaps that improve the flexibility of the PCB while keeping it electrically isolated.
• Sculptured Flex: We etch copper conductors to expose and thicken them, providing better mechanical strength and flexibility, perfect for designs requiring thin, flexible connectors.

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): Combining standard FR4 with high-frequency materials (like Rogers and Taconic) for cost-effective high-performance PCBs, ideal for microwave and RF applications.
• Fusion Bonding PCB (PTFE Fusion): Utilizing PTFE (Teflon) material for extreme high-frequency applications, this process uses high-temperature fusion to eliminate the need for prepreg materials.
• Patch Antenna PCB: We manufacture microstrip antennas with strict tolerances in copper roughness and dielectric thickness, ensuring high efficiency and minimal signal loss in RF communications.
• Cavity Filter PCB: We integrate cavity milling with RF line designs, creating high-performance RF filters for communication devices.
• Metal-Backed PTFE: Using PTFE laminated to metal backplanes, this structure offers superior heat dissipation and is perfect for high-frequency applications.
