What this manufacturer makes
Grandwork Electronics manufactures printed circuit boards in Meizhou, Guangdong. Its official company history dates the business to 2005, and the product catalogue separates aluminum-base, single-sided, double-sided and multilayer boards. The website contains differing plant and output figures, so those figures are not used here as verified capacity. The multilayer product family remains a useful starting point for sourcing, provided the buyer supplies the required stack-up, copper weight, material grade and acceptance criteria.
