sub 25 micron traces averatek asap technology

Introduction to Averatek ASAP

Averatek ASAP (Advanced Semiadditive Process) is a groundbreaking technology that enables the fabrication of sub 25 micron traces on printed circuit boards (PCBs). This innovative process allows for the creation of high-density interconnects, which are essential for the development of advanced electronic devices in various industries, such as telecommunications, aerospace, and medical equipment.

Benefits of Averatek ASAP Technology

1. Finer trace widths: Averatek ASAP enables the creation of traces as small as 15 microns, which is significantly smaller than the traditional PCB manufacturing processes.
2. Improved signal integrity: The reduced trace widths and spacing minimize crosstalk and signal loss, resulting in improved signal integrity and overall performance of the electronic device.
3. Increased design flexibility: With the ability to create finer traces, designers have more freedom to create complex and compact PCB layouts, enabling the development of smaller and more advanced electronic devices.
4. Cost-effective: Averatek ASAP is a cost-effective solution for high-density PCB fabrication compared to other advanced manufacturing techniques, such as modified semi-additive process (mSAP) or subtractive etching.

How Averatek ASAP Works

The Semiadditive Process

Averatek ASAP is based on the semiadditive process, which involves the following steps:

1. Substrate preparation
2. Seed layer deposition
3. Photoresist application and patterning
4. Electroplating
5. Photoresist removal
6. Seed layer etching

Substrate Preparation

The process begins with the preparation of the substrate, which is typically a dielectric material such as FR-4, polyimide, or liquid crystal polymer (LCP). The substrate is cleaned and treated to ensure proper adhesion of the subsequent layers.

Seed Layer Deposition

A thin conductive seed layer, usually copper, is deposited onto the substrate using physical vapor deposition (PVD) techniques such as sputtering or evaporation. This seed layer serves as a conductive base for the subsequent electroplating process.

Photoresist Application and Patterning

A photoresist layer is applied onto the seed layer and patterned using photolithography. The photoresist is exposed to light through a photomask, which contains the desired trace pattern. The exposed areas of the photoresist are then developed and removed, leaving behind a negative image of the trace pattern.

Electroplating

The exposed seed layer is electroplated with copper, which grows within the openings of the photoresist pattern. The electroplating process is carefully controlled to achieve the desired trace thickness and uniformity.

Photoresist Removal

After electroplating, the remaining photoresist is stripped away, revealing the plated copper traces on the seed layer.

Seed Layer Etching

Finally, the exposed seed layer is etched away using a selective etchant, leaving behind the final sub 25 micron copper traces on the substrate.
