Applications Across Industries

  • Customer Electronics

The UPD technology in advanced PCBs, also known as HDI (High Density Interconnector) PCBs, stands out for its superior wiring density per unit area compared to conventional PCBs. It features finer lines and spaces, smaller vias and capture pads, and a higher connection pad density. However, the adoption of advanced PCB technology comes with challenges. Firstly, it is more costly compared to traditional circuit boards. Additionally, the production of high-density circuits requires specialized technology that only a limited number of manufacturers can provide. These high-density circuit boards are susceptible to defects in conductive paths during the production process, particularly open defects, leading to the rejection of the final product. The existing methods for repairing broken conductive paths are expensive, complex, limited, and slow. The constant drive for miniaturization in electronic devices exacerbates these limitations.

To address these challenges, the solution focuses on circuits with the highest path density, crucial for HDI PCB applications. XTPL technology excels in effectively repairing defects occurring during the production stage on previously obtained thin HDI PCB paths. This capability is essential and cost-effective given the high production costs associated with advanced PCBs. Our technology is versatile, capable of printing on various substrates, including conductive or non-conductive materials such as glass, flexible foils (e.g., Kapton, PET, PEN, PDMS), or silicon wafers. XTPL can even print on rough surfaces and 2.5D substrates. The key competitive advantage and breakthrough of the XTPL additive solution lie in its unprecedented precision. The innovation developed by XTPL enables the production of highly advanced circuits using cost-effective and scalable printing methods.
