This includes orders for: <ul type="disc"><li>The first production order for one 510 × 515 mm Ultra ECP ap-p tool from an existing advanced packaging customer in mainland China, with delivery scheduled for the first half of 2027; and</li><li>An evaluation order for one 310 × 310 mm Ultra ECP ap-p tool from a new leading panel-manufacturer customer based in Asia, with delivery scheduled for the fourth quarter of 2026.</li></ul> We believe our Ultra ECP ap-p represents the world’s first commercial horizontal panel-level copper deposition system for large panel market, supporting plating steps across pillar, bump and redistribution layer (RDL) processes. These orders broaden market reach of the Ultra ECP ap-p, support the expansion of ACM’s global customer base, and further strengthen ACM’s position in the panel-level advanced packaging equipment market. “The Ultra ECP ap-p was developed to address increasing requirements for plating uniformity, process stability and production efficiency as advanced packaging moves toward higher levels of integration and larger panel formats,” said Dr. David Wang, President and Chief Executive Officer of ACM. “We are encouraged by the customer response reflected in these orders and remain committed to advancing our panel-level electroplating technology, supporting customer qualification and volume-production adoption, and delivering competitive solutions for advanced packaging manufacturing.” The Ultra ECP ap-p features ACM’s proprietary horizontal electroplating technology and supports panel formats including 310 × 310 mm, 510 × 515 mm and 600 × 600 mm, as well as copper (Cu), nickel (Ni), tin-silver (SnAg) and gold (Au) plating processes. The system features a four-sided sealing dry contact chuck for improved reliability, in-cell rinse functionality to minimize chemical cross-contamination between different plating cells, and a horizontal electroplating design synchronizing a rotating square electrical field with the rotating chuck for superior deposition uniformity.
