Introduction to SAP@Averatek

Averatek Corporation, a leading innovator in advanced printed circuit board (PCB) technology, has developed a groundbreaking Semi Additive Process (SAP) that revolutionizes the manufacturing of high-density interconnects (HDI) and ultra-high density interconnects (UHDI) PCBs. This article will delve into the intricacies of SAP@Averatek, exploring its benefits, applications, and potential impact on the electronics industry.

Understanding the Semi Additive Process

What is the Semi Additive Process?

The Semi Additive Process is a PCB manufacturing technique that combines the advantages of subtractive and additive processes. It involves the selective deposition of copper on a substrate, followed by the removal of excess copper to create the desired circuit pattern. This approach enables the creation of fine-pitch traces and high-density interconnects, surpassing the limitations of traditional PCB manufacturing methods.

Key Steps in SAP@Averatek

1. Substrate Preparation: The process begins with the preparation of a substrate, typically a dielectric material, which serves as the base for the PCB.

2. Seed Layer Deposition: A thin layer of conductive material, such as copper, is deposited on the substrate using techniques like electroless plating or sputtering. This seed layer acts as a foundation for the subsequent copper deposition.

3. Photoresist Application: A photoresist material is applied to the substrate and patterned using photolithography. The photoresist selectively exposes areas where the copper traces will be formed.

4. Copper Plating: Copper is electroplated onto the exposed areas of the seed layer, building up the thickness of the copper traces to the desired level.

5. Photoresist Removal: The photoresist is stripped away, leaving behind the plated copper traces on the substrate.

6. Etching: The exposed seed layer between the copper traces is etched away, isolating the individual traces and creating the final circuit pattern.

Advantages of SAP@Averatek

SAP@Averatek offers several advantages over traditional PCB manufacturing processes:

1. High-Density Interconnects: SAP enables the creation of fine-pitch traces and high-density interconnects, allowing for the miniaturization of electronic devices and improved signal integrity.
