Micro PCBs are not just ultra-thin—they are compact circuit boards with high functional density, essential for space-restricted devices. These include USB controllers, wireless earbuds, hearing aids, smartwatches, intelligent glasses, portable sensors, and other next-generation electronics where the board must support multiple functions within a miniature footprint.
Highleap PCB Factory provides high-quality custom micro PCB manufacturing and assembly in China with support for special materials, precise routing, and fine-pitch components. Our factory is equipped to handle small PCBs with multilayer complexity, designed for structural stability and long-term durability.
Fabrication Capabilities for Miniature and Multi-functional PCBs
At Highleap, we work with OEMs and product developers across industries to deliver small-size boards without compromising performance. Our fabrication strengths include:
- Microvia drilling and laser structuring for high I/O density
- 4–10 layer stack-ups on small boards
- Minimum trace/space: 2 mils (50 µm)
- 0.3 mm pitch BGA and QFN support
- Controlled impedance for USB, Bluetooth, and RF interfaces
- ENIG and OSP finishes suitable for automated assembly
We support designs used in smart home controllers, biometric ID sensors, smart speakers, and compact medical instrumentation. These boards may be small, but they must deliver stable high-speed signals and consistent mechanical behavior.
Explore compatible product families such as HDI PCB, FR4 PCB, and rigid-flex PCB for boards with demanding space and structural integration needs.
Engineering Support for Micro PCB Projects
Micro PCB layout requires careful trade-offs between routing density, thermal limits, and component accessibility. Highleap provides DFM and CAM review support, advising on:
- Copper balancing and ground layer strategies
- Via stacking for compact connectivity
- Differential pair control for USB, HDMI, or RF traces
- Custom edge connectors and pinouts
- High-yield panelization schemes for batch production
Our team uses advanced front-end tools including Gerber viewer and 3D PCB viewer to assist clients in validating their files before fabrication begins. All micro PCB files are reviewed for manufacturability before production starts.
Full-Service Micro PCB Assembly in China
As a complete micro PCB assembly service provider, we support both SMT and hybrid placement for tight layouts, including:
- 0201, 01005, and wafer-level BGA components
- Reflow profiles for high-density placement
- Underfill and edge bonding for shock-prone environments
- X-ray and optical inspection for low-profile joints
We offer turnkey and consigned assembly models, making it easier for engineering teams to transition from prototyping to volume builds with confidence.
More Than Micro — Advanced PCB Materials and Types
Our facility handles not only micro PCBs but also large-format, heat-dissipative, or hybrid-material boards:
- Ultra-thin PCBs for mobile and camera modules
- Metal-core PCBs for power LED applications
- High-Tg FR4 PCBs for automotive and industrial usage
- IC substrate-like multilayer builds for embedded computing
Whether it’s a compact control board or a multilayer interconnect for embedded vision, our team supports reliable PCB builds across categories.
