What this manufacturer makes
Hopesearch manufactures high-density double-sided and multilayer printed circuit boards. Its official site describes the Shenzhen business and the subsequent establishment of a Pingxiang manufacturing operation. The product catalogue includes conventional multilayer and heavy-copper examples, with applications in automotive electronics, communications, consumer products and security equipment. Its process table explicitly separates the layer and thickness limits for samples and volume production. This profile follows the volume-production values and keeps the 22-layer sample ceiling outside the production filter.
