Key offerings include DuPont™ Circuposit™ desmear and electroless copper for mSAP and SAP processes, and DuPont™ Copper Gleam™ electrolytic copper for conformal through-hole plating, which enhances core layer plating technologies. Moreover, DuPont™ Microfill™ acid copper optimizes blind via filling for build-up layers, thereby boosting mSAP and SAP process efficiency. Additionally, DuPont™ Riston® dry film photoresist is essential for a variety of applications, including core and build-up layers, final finishes, and copper pillars.

Visitors to DuPont's booth are invited to connect with our experts and discover integrated solutions designed to drive success in the rapidly evolving electronics industry, including our complete range of offerings for PCBs.

Circuposit™ SAP8000 electroless copper is an innovative metallization technology designed for AI server CPU and GPU chip applications. This ionic base catalyst process is optimized for advanced packaging, meeting the demands for low roughness dielectrics and low Dk and Df properties, essential for fine line and high-frequency designs.

Microfill™ SFP-II-M acid copper offers excellent pattern uniformity, ideal for high-performance computing and AI chip applications. Microfill™ GFH-100 acid copper efficiently fills high aspect ratio through-holes for TGV applications with a unique bridging waveform and one-bath plating. Meanwhile, Microfill™ AHF acid copper supports various hole types in HDI and IC substrates, enabling stacked via structures for simpler processing.

Riston® DI1600 and DI1600M dry film photoresists are advanced solutions that enable fine line direct imaging for IC substrate applications. They provide excellent adhesion and resolution, ensuring high-yield performance.

Solderon™ TS7000 series solder is a SnAg micro bump plating solution for HBM applications. It offers excellent coplanarity, ideal for mixed and fine pitch micro-bumps, and supports both soluble and insoluble electrode plating solutions for added versatility.

CYCLOTENE™ dry-film photo-imageable dielectric (DF-PID) for fan-out panel level package (FOPLP) provides excellent coplanarity through lamination and achieves desired thickness in a single step, unlike liquid dielectrics that require multiple coatings. Additionally, DF-PID for glass core substrate effectively fills through-glass vias (TGV) without voids in glass core substrates, which have successfully passed multi-reflow, biased highly accelerated stress test (bHAST), and high-temperature storage (HTS) reliability tests, showing no delamination or cracking post-assessment.

Pyralux® ML laminates are a breakthrough in non-copper-based materials, providing OEMs with a reliable, customizable solution for high-performance markets. By setting a new industry standard and leveraging advanced polyimide technology, these laminates are poised to expand their impact across critical industries, becoming essential for the next generation of electronic and thermal management applications.

Pyralux® AP flexible copper-clad laminate is a double-sided laminate featuring an all-polyimide dielectric and a unique manufacturing process. It offers exceptional reliability and reduced transmission loss, meeting customer demands for high-speed, high-frequency signal transmission.
