What this manufacturer makes
Huilihua, presented through the Suzhou Circuit website, manufactures multilayer and HDI printed circuit boards in Suzhou. Its official company information dates the operation to 1996. The website describes HDI and conventional multilayer work as part of its PCB business. This listing keeps the product family separate from designed production capacity and avoids interpreting a capacity plan as current output. Buyers considering HDI should provide the sequential-lamination structure and microvia arrangement alongside the electrical requirements.
