Rigid-Flex PCB Technology

Release time: 28/08/2017

Micro vias HDI rigid flex circuit boards technologies include blind and/or buried vias processes and often micro vias with a higher circuitry density than traditional PCB's. Integrating HDI PCB Technologies with Rigid-flex PCB and HDI PCB. Every Layer Interconnect(ELIC HDI PCB) & Rigid-flex PCB are now available at Hemeixin Electronics Co., Ltd.


rigid-flex circuit


HDI PCB Boards contain blind and/or buried vias and often contain micro vias of .006 or less in diameter. They have a higher circuitry density than traditional circuit boards.

There are 6 different types of HDI PCB boards, through vias from surface to surface, with buried vias and through vias, two or more HDI PCB layer with through vias, a passive substrate with no electrical connection, coreless construction using layer pairs and alternate constructions of coreless constructions using layer pairs.

Rigid-Flex circuit boards are composed of a combination of rigid and flexible circuit boards that are permanently connected to one another.


The proper application of Rigid-Flex circuit boards offers optimum solutions for difficult, limited space conditions. This technology offers the possibility of a secure connection of device components with the assurance of polarity and contact stability, as well as a reduction in plug and connector components.


Additional advantages of Rigid-Flex circuit boards are dynamic and mechanical stability, the resulting 3-dimensional freedom of design, simplified installation, space savings, and maintenance of uniform electrical characteristics.
