ACM Research Ships a Production Panel-Plating Tool Beyond China

ACM Research has shipped a panel-level packaging tool designed for production to a customer outside mainland China. The shipment is small in disclosed financial terms because the company named neither the buyer nor the order value, but it is strategically relevant for a supplier whose revenue remains heavily concentrated in China.

The company shipped its first 310 × 310 millimeter Ultra ECP ap-p horizontal electroplating production system to an Asian customer outside mainland China. ACM described it as what it believes is the world's first production tool of that size and design. That is a company claim, not an independently verified industry ranking.

Panel-level processing uses larger rectangular substrates rather than individual round wafers, with the aim of producing more advanced-package units per run. Electroplating builds metal structures and interconnects, so thickness uniformity, contamination control and repeatability can affect yield. Those requirements become harder as packages add more connections and taller copper structures for AI and other high-performance chips.

ACM's system supports copper, nickel, tin-silver and gold plating. The copper chamber uses a high-speed paddle designed for 300-micron copper pillars at high plating rates. Other features include a four-sided dry-contact chuck, in-cell rinsing to reduce chemical carryover and a patent-pending design that coordinates chuck rotation with a rotating rectangular electric field. The company said these features are intended to improve deposition uniformity and production reliability.

The shipment follows a 515 × 510 millimeter research-and-development tool delivered in 2025. Moving from an R&D installation to a production system is meaningful because production acceptance can require tighter uptime, process-control and service standards. However, one shipment does not establish broad adoption, recurring revenue or customer qualification across additional fabs.

The geographic detail is especially important. ACM's June 2026 filing said substantially all revenue in the first half came from customers in mainland China. Three customers accounted for 43.5% of second-quarter revenue, while four customers represented 52.4% of accounts receivable. A delivery elsewhere in Asia therefore supports management's diversification objective, but it is too early to conclude that concentration has materially changed.

ACM reported second-quarter revenue growth of 36%, with electrochemical plating revenue up 168% and advanced-packaging revenue up 153%. It also ended June with about $1.0 billion in net cash and raised its 2026 revenue-growth outlook to 25% to 30%. Those figures show that the new system enters a product area already growing quickly, although the company did not quantify how much this particular tool contributes.

The next evidence should be customer acceptance, repeat orders and revenue outside mainland China. Until those appear, the shipment is best viewed as a credible product and diversification milestone, not proof that ACM has solved its geographic and customer-concentration risks.
