Low Noise for Clear Sound
Noise in audio equipment often comes from the board, not the speaker. Boyastar started in 2008. Our factory is in Guangde Economic Development Zone, Anhui, China. The plant covers 19,000 square meters. We have more than 150 employees. We produce about 50,000 square meters of PCB each month. The Audio Equipment PCB service is made for low-noise and high-fidelity scenes. This board fits audio equipment, earphones, microphones, mixing consoles, amplifiers, audio decoders, audio interfaces, and recording equipment. We use FR-4 as the base material. Low-noise design, high-fidelity design, and impedance control are key features. Low-noise boards, high-fidelity boards, and high signal-to-noise ratio boards are all within our experience.
Grounding and Filter Support
Layer count ranges from 2 to 10 with flexible selection. High TG FR-4 and high CTI FR-4 are available. Blind and buried vias and BGA are also available. Immersion gold, HASL, and OSP are common. Immersion silver, immersion tin, and hard gold plating are available on request. Our engineering team has more than ten engineers. They do low-noise design review and manufacturability analysis. They send a quote and lead time within 24 hours. We accept OEM and ODM orders. We build from drawings or samples. Layer count, board thickness, copper thickness, base material, surface finish, solder mask color, silkscreen color, impedance, blind and buried vias, BGA, and packing all follow buyer requirements. Audio boards are sensitive to power ripple. We suggest adding filter capacitors at key positions. We also suggest star grounding for the ground layout. This reduces background noise. Earphones and microphones are very sensitive to background noise. We separate the power layer and signal layer in the stack-up. This reduces crosstalk.
Noise Tests and Full Traceability
High noise is the top risk for audio boards. We run low-noise tests, signal-to-noise ratio tests, and impedance tests. We confirm the first article before release. We keep records for every step from incoming material to final shipment. Our quality team has more than 20 people. Every board gets electrical testing before packing. We use AOI and flying probe testing. We accept third-party inspection. Our factory holds IATF16949, ISO9001, ISO14001, and ISO45001. We hold Underwriters Laboratories product safety certification. The file number is E528398. These approvals help buyers meet North American and European market requirements. The Audio Equipment PCB service gives buyers a clean path for high-fidelity designs.
