Sub-25 Micron Traces with Averatek ASAP Technology

Introduction to Averatek ASAP Technology

Averatek ASAP (Advanced Semi-Additive Process) is a revolutionary technology that enables the manufacturing of high-density interconnects with trace widths and spaces below 25 microns. This innovative process is transforming the electronics industry by allowing the creation of smaller, faster, and more efficient electronic devices. In this article, we will explore the key features, benefits, and applications of Averatek ASAP technology.

How Averatek ASAP Technology Works

The Semi-Additive Process

Averatek ASAP technology is based on a semi-additive process, which involves the selective deposition of copper on a substrate. The process begins with the application of a thin seed layer of copper on the substrate, followed by the deposition of a photoresist layer. The photoresist is then patterned using photolithography, exposing the areas where the copper traces will be formed.

Next, copper is electroplated onto the exposed areas, forming the desired trace pattern. The photoresist is then removed, and the seed layer is etched away, leaving only the copper traces on the substrate. This process allows for the creation of extremely fine traces with high aspect ratios, enabling the manufacturing of high-density interconnects.

Comparison with Traditional Subtractive Processes

Traditional PCB manufacturing processes, such as subtractive etching, have limitations when it comes to creating fine traces. Subtractive processes involve the removal of unwanted copper from a fully copper-clad substrate, which can lead to undercutting and other issues that limit the minimum achievable trace width.

In contrast, Averatek ASAP technology’s semi-additive process allows for the selective deposition of copper, eliminating the need for etching and enabling the creation of much finer traces. This results in higher-density interconnects and improved signal integrity.

Benefits of Averatek ASAP Technology

Miniaturization and High-Density Interconnects

One of the primary benefits of Averatek ASAP technology is its ability to create sub-25 micron traces, enabling the manufacturing of high-density interconnects. This miniaturization allows for the development of smaller, more compact electronic devices, such as smartphones, wearables, and IoT sensors.

Improved Signal Integrity and Reduced Crosstalk

The fine traces and high-density interconnects made possible by Averatek ASAP technology also lead to improved signal integrity and reduced crosstalk. Smaller traces and shorter signal paths result in reduced parasitic capacitance and inductance, which can improve signal quality and reduce signal distortion.

Cost-Effective Manufacturing

Averatek ASAP technology offers a cost-effective solution for manufacturing high-density interconnects. The semi-additive process eliminates the need for expensive materials and equipment associated with traditional subtractive processes, reducing overall manufacturing costs.
