Sub-25 Micron Traces with Averatek ASAP Technology

 

Introduction

Advancements in printed circuit board (PCB) technology have enabled the miniaturization of electronic devices, leading to the development of smaller, more compact, and more powerful electronic systems. One of the most significant challenges in PCB design is achieving high-density interconnects while maintaining signal integrity and reliability. Averatek's ASAP (Advanced Signal Adaptation Process) technology has emerged as a game-changer in this regard, enabling the fabrication of sub-25 micron traces on PCBs.

What is ASAP Technology?

ASAP technology is a proprietary process developed by Averatek that allows for the creation of extremely fine traces on PCBs. This technology combines advanced photolithography techniques, specialized materials, and optimized manufacturing processes to achieve trace widths and spacing as small as 15 microns (0.0006 inches). In comparison, traditional PCB manufacturing processes typically produce trace widths and spacing of around 75 microns (0.003 inches) or larger.

Benefits of Sub-25 Micron Traces

The ability to fabricate sub-25 micron traces offers several significant advantages for PCB design and manufacturing:

1. Increased Circuit Density

With smaller trace widths and tighter spacing, more interconnects can be accommodated within the same PCB area. This increased circuit density enables the integration of more functionality into a compact form factor, leading to smaller and more powerful electronic devices.

2. Reduced Electromagnetic Interference (EMI)

Narrower traces generate lower electromagnetic emissions, resulting in reduced electromagnetic interference (EMI) between closely spaced signals. This is particularly important in high-frequency applications, where EMI can severely degrade signal integrity and system performance.

3. Improved Signal Integrity

Shorter trace lengths and tighter coupling between signal and reference planes contribute to improved signal integrity, reducing crosstalk and minimizing signal distortion. This is crucial for high-speed digital circuits and high-frequency analog applications.

4. Reduced Power Consumption

Shorter interconnects result in lower parasitic capacitance and inductance, leading to reduced power consumption and improved energy efficiency in electronic devices.

5. Enhanced Design Flexibility

The ability to route traces with sub-25 micron dimensions allows for greater design flexibility, enabling more complex layouts and increasing the potential for design optimization.

Design Considerations for Sub-25 Micron Traces

While ASAP technology offers numerous advantages, designing and manufacturing PCBs with sub-25 micron traces requires careful consideration of various factors:

1. Material Selection

The choice of base materials, such as laminates and solder masks, plays a crucial role in achieving reliable and consistent sub-25 micron traces. Averatek has developed specialized materials optimized for ASAP technology, ensuring compatibility with the manufacturing process and providing the necessary dimensional stability and performance characteristics.

2. Manufacturing Tolerances

Tolerances for trace width, spacing, and registration become increasingly critical as trace dimensions decrease. Averatek's ASAP technology employs advanced manufacturing processes and stringent quality control measures to ensure consistent and accurate trace geometries.

3. Signal Integrity Considerations

At sub-25 micron dimensions, signal integrity becomes a critical concern. Factors such as impedance control, crosstalk, and high-frequency effects must be carefully analyzed and managed through proper design practices, including the use of appropriate reference planes, controlled impedance traces, and careful signal routing.

4. Thermal Management

The increased circuit density enabled by sub-25 micron traces can result in higher heat dissipation within a confined area. Effective thermal management strategies, such as the use of appropriate thermal interface materials (TIMs) and heat sinks, are essential to ensure reliable operation and prevent premature component failure.

5. Manufacturing Capabilities

Designing and manufacturing PCBs with sub-25 micron traces requires specialized equipment and expertise. Averatek has invested in state-of-the-art manufacturing facilities and highly trained personnel to ensure consistent and reliable production of ASAP technology-based PCBs.
