It uses a hybrid stack-up of FR-4 and high-frequency materials, which deliver clear and smooth sound performance. It can be used in high-end network streaming players.
This PCB features 6oz–10oz copper thickness and extremely low-resistance current paths. It is suitable for ultra-high-power electrical devices.
This type of PCB has flexible bending capability and can be used in foldable headphones, ultra-thin Soundbar internal connections, and VR headset audio modules.
Features of Consons’ Speaker PCBs
We support 1oz–6oz inner layer and up to 10oz finished outer layer copper thickness; this helps reduce heat generation and mitigate thermal breakdown risks in Class-D amplifiers.
For Bluetooth antennas and differential digital audio signal lines, we strictly control the impedance tolerance within ±5%, to prevent signal reflection and channel crosstalk.
We use high-Tg materials with a Tg of 170°C or more, which enables the product to deal with temperatures from -40°C to +125°C. We also perform 1,000 thermal cycle tests to verify this.
Consons uses high-frequency materials such as Rogers RO4000 and RO3000 with a dissipation factor (Df) of 0.0037, which helps preserve weak audio signal details best.
Comprehensive Full-Process Inspection System
We have built a complete quality control system for the entire process. All the PCBs will be inspected by AOI to detect circuit defects after assembly, like opens or shorts. For all multilayer and HDI PCBs, our engineers will carry out X-ray inspection for layer alignment and verify the registration precision.
In addition, all the finished PCBs undergo flying probe testing. For mass production orders, we also use test fixtures for double verification. If you need, we can also provide TDR impedance testing and waveform reports.
Strong Intellectual Property (IP) Protection System
We offer strong protection for your intellectual property and engineering data security. We will sign an NDA with you, to provide legal protection for your Gerber files, BOM, and other confidential documents.
In addition, we carry out network isolation, port control, and file encryption with tiered access management during production. For prototype leftover boards, defective boards, films, we will keep the entire records, perform physical destruction, and prevent any leakage of your design data.

Applications of Speaker PCB
In automotive electronics, the speaker PCBs can be used for in-vehicle infotainment amplifiers, subwoofer amplifiers, and vehicle AVAS pedestrian warning sound systems. Our products can handle wide temperature ranges, vibration, and high-temperature, high-humidity conditions in engine compartments, providing stable audio output.
In smart home IoT and professional consumer audio applications, the speaker PCBs can be used in smart speakers, home theater Soundbars, stage-powered line array speakers, Hi-Fi amplifiers, and portable Bluetooth speakers. They can be integrated into compact spaces and deliver high-quality audio performance.
In medical equipment areas, speaker PCBs can be used in MRI patient communication systems, high-precision audiometers, and hearing aids. It achieves strict cleanliness control while suppressing noise and signal crosstalk. This ensures reliable, high-fidelity transmission of delicate audio signals.
It can also be used in digital guitar effects processors, synthesizers, electronic drums, and built-in amplifiers for silent guitars. We can achieve effective suppression of digital circuit crosstalk in PCBs; thus, the PCB will give you pure, high-quality audio output.
For indoor applications with low or medium power levels, regular FR-4 may be enough.
However, if you plan to use the PCB in automotive or outdoor speakers, or in RF audio circuits, standard FR-4 substrates may cause signal loss, or even circuit failure. In these applications, you can choose upgraded high-Tg FR-4, metal core PCBs, or high-frequency materials.
We use advanced thermal management solutions, including up to 10oz heavy copper, metal core PCB (MCPCB) substrates, optimized thermal via arrays, and ENIG surface finishing. These technologies help the PCB effectively dissipate heat from high-power Class D amplifiers and prevent PCB overheating.
Yes. We can set up an annual supply agreement and arrange the shipment quantity each time. You can choose weekly, monthly, or other delivery intervals.
During the prototyping stage, double-sided speaker PCBs will usually be shipped within 24 hours. For mass production, regular orders usually need 7–12 working days.
We support rush orders, and the lead time can be reduced by 30%–50% compared with standard orders.
All materials we use, such as substrates, inks, and surface finishes, meet the latest EU SVHC and RoHS 2.0 standards. We can provide CoC certificates and third-party environmental test reports issued by laboratories with CNAS or ILAC-MRA recognition.
If you find any issue, just send us photos and the batch number. We will begin checking the production records within 4 hours. After confirmation, we will make new replacements and ship them to you by the fastest international courier.
Of course. We provide a complete service from schematic design to manufacturing files.
Accurate impedance control helps keep high-fidelity and accurate audio output. Incorrect or mismatched impedance can lead to channel interference, unstable sound, and inaccurate stereo imaging.
