Products
DYCONEX offers a wide range of high-end PCB solutions that are tailored to the most demanding applications. Its core products include:
Flexible PCBs
Flexible printed circuit boards are used in devices that require high-density signal routing in compact or dynamic environments. DYCONEX’s flex PCBs offer multi-layer construction, ultra-fine lines and spaces, and high aspect ratio vias, enabling compact and lightweight end-products. The achieved reliability of the flexible printed circuit boards is one of the key strengths and enables the use in medical and challenging environments.
Rigid-Flex PCBs
These combine the benefits of rigid and flexible substrates, making them ideal for complex three-dimensional designs. DYCONEX provides rigid-flex PCBs with custom stack-ups, optimized for durability, space-efficiency, and reduced connector requirements.
Ultra HDI Substrates
DYCONEX has developed and industrialized ultra-high-density interconnect substrates with features such as line/space down to 8 microns, laser-drilled microvias, and fine-pitch BGA support. These are used in applications where size, weight, and electrical performance are critical.
Implantable Substrates & Electrodes
Specializing in biocompatible materials and surface treatments, DYCONEX provides substrates for implantable devices including neural interfaces, cardiac implants, and active hearing devices. Products are customized for shape, thickness, flexibility, and longevity.
Custom Solutions
Many of DYCONEX’s products are developed in close collaboration with customers, resulting in highly customized interconnect solutions with unique mechanical, thermal, and electrical properties.
Technologies
DYCONEX’s technology portfolio encompasses some of the most advanced PCB processes available today:
High-Density Interconnect (HDI)
DYCONEX was an early adopter of HDI technology and continues to refine these processes for medical and scientific use cases. The company’s HDI capabilities include microvia technology, via-in-pad structures, stacked vias, and ultra-fine lines/spaces.
Semi-Additive Process (SAP)
Using advanced SAP and mSAP techniques, DYCONEX achieves exceptional trace definition and layout accuracy. This is essential for next-generation medical implants and high-frequency circuits.
Laser Direct Imaging (LDI)
High-resolution LDI systems enable precision patterning for HDI and flex-rigid PCBs. This improves yield, registration accuracy, and the ability to support dense component placement.
Biocompatible Materials
DYCONEX works with a wide range of medically approved materials including polyimide, LCP (Liquid Crystal Polymer), and other specialty films. These are selected based on their flexibility, durability, and chemical stability in biological environments.
Cleanroom Manufacturing
Cleanroom production lines ensure particle-free manufacturing environments, a necessity for producing substrates used in implantable devices and high-reliability electronics.
