Procurement Guide
Frequently Asked Questions
Common questions from electrical engineers and international sourcing managers regarding Aluminum PCB projects.
What thermal conductivity is recommended for my LED or power electronics design?
For general indoor lighting and standard consumer fixtures (up to 10W), 1.0–1.5 W/m·K is cost-efficient and widely adopted. For high-output commercial LED luminaires, floodlights, automotive headlights, and power supply switches operating above 20W, we recommend 2.0 W/m·K to 3.0 W/m·K. Extreme power densities or industrial motor drives benefit from our advanced 5.0 W/m·K metal core substrates.
How do you ensure electrical isolation between the aluminum plate and copper circuitry?
Our metal-core laminates incorporate a thermally conductive, electrically insulating polymer-ceramic dielectric layer. Every fabricated board undergoes a dielectric withstand (Hi-Pot) test at 2,000V–4,000V AC to guarantee that zero breakdown occurs between the copper traces and the grounded aluminum base.
What are your guidelines for V-scoring and panelization on Aluminum PCBs?
Aluminum requires specialized diamond-tipped scoring blades. We recommend a web thickness (remaining core) of 0.3mm to 0.5mm depending on total board thickness, with a standard scoring angle of 30° or 45°. Our engineering team reviews panel step-and-repeat arrays during the initial DFM check to ensure easy separation without bending the metal base.
Can Shenzhen VUKO Electronics Co., Ltd. handle turnkey SMT assembly on Aluminum boards?
Yes. We operate dedicated SMT lines optimized for metal-core boards. Because aluminum dissipates heat rapidly during soldering, we utilize multi-zone reflow profiles with bottom pre-heating to prevent cold joints while safeguarding heat-sensitive LEDs, sensors, and power ICs.
How quickly can you provide quotations and sample shipments?
Upon receiving your Gerber files, NC drill files, and BOM, our engineering department will complete the DFM verification and issue a formal quotation within 24 hours. Rapid prototypes are typically ready to ship in 3 to 5 business days, with mass production runs delivered in 10 to 14 days.
