Hdi Pcb
HDI PCB is widely used to reduce the weight and overall dimensions of products, as well as enhancing the electrical performance of the device. It's regularly found in mobile phones, touch-screen devices, laptop computers, digital cameras, 4G network communications, also prominently featured in medical devices as well as various electronic aircraft parts and components.
Over the course of a decade in business, Topscom has established a hard-earned reputation for manufacturing PCBs of the highest quality. Our custom PCB manufacturing capabilities enable you to get the finest quality HDI PCBs at competitive prices without min order quantity requirement. Our team run design for manufacture check on your custom PCB file and consult with you to ensure it is ready for manufacturing and that your boards will meet your performance requirements. We also have an on-site quality control department to verify the finished product meet your high quality standards.

HDI Pcb Specification
High density interconnect (HDI) PCBs represent one of the fastest-growing segments of the printed circuit board market. Because of its higher circuitry density, the HDI PCB design is able to incorporate finer lines and spaces, smaller vias and capture pads, and higher connection pad densities. A high density PCB features blind and buried vias and often contains microvias that are .006 in diameter or even less.
Key HDI PCB Benefits
The evolution of high density PCB technology has given engineers greater design freedom and flexibility than ever before. Designers now have the ability to place more components on both sides of the raw PCB if desired. In essence, an HDI PCB gives designers more space to work with, while allowing them to place smaller components even closer together. This ultimately results in faster signal transmission along with enhanced signal quality.
