Any Layer HDI PCB Features

Microvias and Layer Interconnects

You will notice that any layer hdi pcb​ stands out because of its advanced use of microvias. These tiny holes, created by laser drilling for vias, connect any two layers in the printed circuit board. This method gives you more design freedom and allows for high-density connections. Microvias are much smaller than traditional through-hole vias, which means you can pack more features into less space. You also get better signal quality because microvias create shorter paths for electrical signals. This reduces signal loss and improves integrity, which is important for high-speed applications.

Microvias also help reduce electrical noise and electromagnetic interference. You get improved performance and reliability in your pcb, especially when you need high-density circuit boards for demanding applications.

Here is a comparison of microvias and traditional through-hole vias:

Aspect	Microvias	Through-Hole Vias
Size	Smaller	Larger
Aspect Ratio	Up to 20:1	Lower
Signal Integrity	Improved	Standard
Noise Reduction	Enhanced	Limited
Thermal Management	Better	Standard
Durability under Stress	Superior	Standard

LTPCBA uses advanced techniques like UV laser drilling and controlled depth drilling to ensure precise connections between layers. Their expertise in microvia technology means you get a pcb with excellent electrical performance and long-term reliability.

High Density and Compact Design

Any layer hdi pcb​ technology lets you achieve a much higher density than standard boards. You can use fine-pitch components and stack microvias to connect multiple layers without making the board bigger. This efficient use of space is key for modern devices like smartphones and wearables, where every millimeter counts.

• You can reduce pcb size by 30-50% compared to traditional designs.
• HDI boards often have 8, 10, or even 20 layers in the same or smaller footprint as a standard 4-6 layer board.
• Minimum trace width and spacing can be less than 0.005 inches, and microvias can be as small as 0.008 inches in diameter.

The high density and compact design of any layer hdi pcb​ allows you to fit more functions into smaller devices, making them ideal for advanced applications in consumer electronics and telecom.

LTPCBA uses advanced materials and manufacturing processes to achieve this level of density. They use sequential lamination, plasma etching, and electroless copper plating to build up layers and ensure strong, reliable connections. Their process supports all available circuit board materials, so you can choose the best option for your application.

Reliability and Performance

You can trust any layer hdi pcb​ for its outstanding reliability and performance. These boards use low-CTE, high-performance dielectric materials, which handle temperature changes better than standard FR-4 materials. LTPCBA tests every pcb using advanced inspection methods like flying probe testing, AOI, and X-ray analysis. They follow strict industry standards and achieve a 99.8% pass rate, even for complex applications.

Aspect	HDI PCBs	Standard PCBs
Conductor Density	Higher conductor density	Lower conductor density
Via Density	5-10 times higher density of vias	Standard via density
Dielectric Layers	Ultra-thin dielectric layers	Standard thickness dielectric layers
Thermal Reliability Tests	Temperature cycling tests (-40℃ to +115℃)	Less rigorous thermal testing
Material Used	Low-CTE high-performance materials	Standard FR-4 materials
