SHC Electronics Limited was founded in 2017 as a high-tech enterprise, specializing in the manufacturing of intelligent controller PCBA, as well as the research, design, and production of intelligent products. We focuses on providing various intelligent controller products and corresponding solutions for industrial controllers, medical products, new energy vehicle electronics, and new smart home applications.
Our factory has obtained certifications such as ISO 9001:2015, ISO 1345:2016, IATF 16949 for automotive, and ISO 13485 for medical quality system certifications. We have the capability to assist customers in completing RoHS and Reach environmental certifications, as well as supporting them in product reliability testing and failure analysis.
Distinguishing itself from factories focused solely on manufacturing, SHC Electronics Limited also provides services such as PCBA design and development, BOM material procurement, DFX evaluation, and other technical support. From the research and development stage to prototyping, small to medium-scale production, and mass production, we provide corresponding manufacturing solutions.
During the product design stage: we can assist with material selection and assist with DFX design, assist with designing the original schematic diagram and Layout design, and the design of test plans. During the sample verification stage, we can provide 10-day fast prototyping, including PCB manufacture, material procurement, and SMT assembly. During the mass production stage, we can assist with mass procurement cost reduction, assist with capacity ramp-up, throughput yield improvement, process failure analysis, verification of key processes, and verification of process parameters.
The decoding board implements H265/H264 video decompression playback function, supporting up to 4K (3840*2160) decoding playback and backward compatibility with various resolutions and frame rates. When used in conjunction with the H265 encoding board and COFDM transmitting and receiving module, it can achieve low-latency high-definition digital wireless image transmission function. Actual testing shows that at 1080P@60, the video latency can be around 250ms. This latency refers to the delay from the HDMI video input on the transmitting end to the HDMI video output on the receiving end, excluding the delay from the camera on the transmitting side (we measured a delay of about 70ms for a certain brand of DSLR and about 130ms for a well-known brand of action camera);
The decoding board supports up to 4 channels of video decoding playback simultaneously, with split-screen display (requires flashing multi-channel video decoding firmware).
It supports AES decryption functionality (matches with the encryption from the transmitting end, and the password can be set through the parameter configuration panel);
