HDI Rigid-Flex PCB for Beton

HDI Rigid-Flex PCB

HDI Rigid-Flex PCBs have blind and buried vias with a very thin 0.6mm rigid area thickness. This HDI Rigid-Flex PCBs are an not easy design, but with the help of advanced equipment and decades of manufacturing experience, we successfully manufacture this HDI Rigid-Flex PCBs with zero defect rate.

HDI Rigid-Flex PCB, also named as multilayer rigid-flex circuit with the advantages of both rigid and flexible pcb. And HDI Rigid-Flex PCBs have a higher interconnect or trace density than normal PCBs. This enables the use of smaller vias, microvias and advanced package techniques.

HDI rigid-flex circuit boards are made by bonding multilayers thin flexible circuit materials. The layers are first laminated together to form a single flex PCB. Adhesives are then used to bond the layers together. These resulting laminated boards are withstand high temperature and pressure to ensure a tight bond between the two rigid and flex layers.

HDI rigid-flex boards feature high circuit density, heat dissipation, and chemical resistance, so they are mainly used in a variety of electronic devices, including mobile phones, laptops, and tablets, but also in medical equipment, military equipment, and the aerospace industry.

HDI Rigid-Flex PCB Stackup

The rigid-flex PCB structure uses blind and buried holes, that is, HDI rigid-flex circuit. HDI rigid-flex circuit boards are typically driven by high-density BGA applications requiring vias in pads. This type of construction may also require an asymmetric construction if the blind vias need to be interconnected to the flex circuit layer.

2R+2F+2R Every layer interconnection (ELIC) HDI Rigid-flexPCB Stackup

As multilayer rigid-flex circuits with more layer counts and the circuit layers of rigid-flex boards are becoming thinner, new HDI technologies are used to increase interconnect density. Every layer interconnection (ELIC) is a higher HDI technology that allows PCB design engineers to Allows PCB design engineers to create ultra-thin, more flexible rigid-flex boards with high functional density. The advanced Every layer interconnection (ELIC) HDI rigid-flex boards contain multilayer copper-filled stacked microvias in pads to achieve more complex interconnects. Please see the bellow 2R+2F+2R Every layer interconnection (ELIC) HDI Rigid-flexPCB Stackup.

As we all know, the HDI PCB manufacturing process is complex. And the HDI rigid-flex pcb also is complex and challenged. Please see the 6 layer HDI Rigid-Flex PCB manufacturing process.

HDI rigid-flex PCB Advantages

Ordinary rigid-flex boards are increasingly unable to meet some durable, reliable, high-quality, and high-density requirements, so engineers began to develop HDI rigid-flex boards. Here are some advantages of HDI Rigid-Flex boards, which have more advantages than ordinary Rigid-Flex boards, please see the advantages below:

Thinner: HDI Rigid-Flex PCB can be as thin as 0.1 mm because of utilizing HDI technology.

Lighter Weight: HDI Rigid-Flex PCBs are 50% lighter than common Rigid-Flex boards, making them ideal for products where weight matters.

More flexible: HDI rigid-flex boards are more flexible, making them easier to use and install in a variety of applications.

Higher reliability: HDI rigid-flex PCBs are more reliable because they have thinner circuits and higher interconnect density.
