In the modern digital landscape, the transmission, decoding, and processing of ultra-high-definition (UHD) audio and video signal chains require robust hardware backbones. As a leading PCB Audio and Video Supplier & Exporter, Corexis Memory Technology Co., Ltd. addresses the strict impedance control, high frequency stability, and thermal management parameters essential for flawless digital-to-analog conversion and multi-channel high-bandwidth streaming.
Utilizing high-performance substrates such as Shengyi FR4 High TG170 and Rogers 4000 Mixed Pressure stack-ups, our board designs preserve weak high-frequency signal waveforms. We mitigate dielectric losses and crosstalk in HDMI 2.1, DisplayPort 1.4, and SDI circuit runs to guarantee jitter-free, zero-latency AV streams.
Audio decoders and video deserializers operate on tight differential impedance tolerances (typically 90Ω for USB, 100Ω for LVDS/HDMI). Our automated optical inspection (AOI) and time-domain reflectometer (TDR) test stations verify matching track geometry on every production batch to prevent signal reflection.
High-speed digital processing units generate significant EMI that can compromise analog audio pre-amplifiers. Our multi-layer layout topologies incorporate dedicated ground plane isolation and conformal metal shielding to maintain excellent signal-to-noise ratios (SNR) and total harmonic distortion (THD+N) levels.
Corexis Memory Technology Co., Ltd. is a professional DDR5 and DDR4 memory manufacturer dedicated to delivering high-performance DRAM solutions and comprehensive PCB assembly services for global OEM, ODM, and brand customers. Since our establishment in 2016, we have focused on memory technology innovation, advanced SMT manufacturing, and strict quality management systems. Our advanced products are widely used in desktop PCs, laptops, servers, industrial computers, embedded systems, and AI-driven AV decoding hardware.
With a modern manufacturing facility covering 21,800 m², Corexis integrates R&D, SMT production, testing, packaging, and quality assurance under one roof. Our experienced engineering team continuously develops reliable, high-speed DDR4/DDR5 components and complex PCBA structures that meet international standards and the evolving demands of the global market.
To ensure 100% reliability, our products undergo a strict 5-stage QC flow:
Our manufacturing facilities in China leverage localized electronic clusters to provide rapid component sourcing, low logistics costs, and highly scalable manufacturing capacity.
Being situated at the heart of the global electronics component supply chain, we secure premium raw materials (substrates, copper foils, ICs, solder pastes, and passive components) with zero delay. This eliminates upstream supply disruptions and ensures competitive unit pricing for high-density audio and video decoding assemblies.
Our facility is equipped with automated SMT placement lines, high-speed solder paste printing machinery, multi-zone reflow ovens, and wave-soldering lines. We support fine-pitch passive elements down to 0201 packages and advanced Ball Grid Array (BGA) placements required for high-bandwidth DRAM modules and processing chipsets.
With 128 dedicated R&D engineers, we can translate electronic schematic designs into physical, tested PCBA prototypes in a fraction of the standard lead time. This allows global AV system integrators and consumer electronics brands to shrink their time-to-market cycles significantly.
Meeting the demands of global tier-1 brand owners, distributors, and industrial equipment builders requires customizable solutions and reliable high-volume manufacturing output.
Corexis offers flexible design options, including custom board sizing, component selections, layer configurations, and firmware optimizations. Our DRAM and memory modules support customization for:
We possess 8 years of export experience, regularly shipping high-reliability hardware to North America, Europe, Southeast Asia, South America, and the Middle East. We ensure complete customs compliance, structured export documentation, and safe transit via protective anti-static packaging configurations.
We support critical industry certifications to ensure hassle-free market entry and absolute safety compliance across international jurisdictions.
All manufactured PCBA boards and DRAM modules conform to lead-free environmental directives.
Strict compliance protocols ensure low radiated EMI levels, complying with American and European emission regulations.
Our PCB substrates conform to standard flame retardancy rules for commercial deployment.
We offer localized multi-lingual support, helping field engineers resolve schematic integrations and driver conflicts.
Our electronic products are deployed inside demanding systems that require uninterrupted operation and high signal fidelity.
Our FR4 audio decoder PCB assemblies drive premium amplifiers, smart speakers, and home theater processors, delivering high-resolution digital decoding (up to 32-bit/384kHz PCM) with negligible noise floor.
Integrating high-speed DDR4/DDR5 RAM ensures fast buffer memory write-cycles. This setup is perfect for smart IP cameras, multi-input matrix switchers, and AI-enabled video analytics boxes.
Our heavy-duty PCB design provides reliable thermal paths for control boards in outdoor and indoor LED displays, ensuring stable performance during continuous 24/7 video rendering.
Inside our 21,800 m² state-of-the-art facility, our specialized machinery and cleanroom environments guarantee maximum yield rates and component reliability.
For high-definition video circuits carrying bandwidths like HDMI 2.0/2.1 or DisplayPort, we recommend high-TG (Tg170+) FR4 from reputable brands like Shengyi, or Rogers series (e.g., Rogers 4003C/4350B) in mixed-pressure configurations. These substrates maintain a stable dielectric constant (Dk) and low dissipation factor (Df) to minimize signal losses at multi-gigahertz frequencies.
Live high-bitrate video decoding requires substantial bandwidth. While DDR4 memory modules running up to 3200MHz satisfy HD streaming, DDR5 solutions offer twice the bandwidth and sub-channel architecture, reducing dropped frames during real-time 4K/8K video processing and multi-channel IP network camera feeds.
We maintain physical isolation between digital processing logic circuits and analog pre-amplifier zones. By routing differential audio traces symmetrically and avoiding digital noise injection using decoupling capacitors and ferrite beads, we achieve minimal noise floor and ultra-pure sound reproduction.
Our design and manufacturing flows are certified under ISO9001. Final products carry CE, FCC, RoHS, and REACH markings. We strictly run 100% full visual and mechanical testing, alongside functional system boots before shipping.
We offer custom PCB layouts, customized heat-spreader colors and shapes, private label silkscreen/laser engraving, and customizable memory configurations (such as DDR4 4GB, 8GB, 16GB, or 32GB capacities at specific speeds and timing latencies).
