Jinsung Electronics, based in Korea, is a seasoned manufacturer of high-quality printed circuit boards. Since 1995, they've specialized in surface-mount technology (SMT) and custom PCB fabrication—particularly flexible, rigid-flex, and HDI circuit boards. Their in-house setup ensures fast turnaround, superior quality, and extensive customization options.

What is an HDI PCB?
HDI stands for High-Density Interconnect Printed Circuit Board. It is a PCB technology that allows higher wiring density by using micro-blind and buried vias (very small copper-plated holes). HDI PCBs are compact, high-performance, and commonly used in advanced electronics where space and performance are critical.

Compared to standard PCBs, HDI boards:
 Have smaller vias, pads, and traces.
 Use blind/buried vias instead of only through-holes.
 Allow higher component density in a smaller area.

What Core Technology Does Jinsung Use for HDI PCB?
Jinsung Electronics has specialized microvia and laser-drilling technology as the foundation of their HDI development. Their core technologies include:
1. Laser-Drilled Microvias
o Diameter sizes: 0.006" (150 µm), 0.005" (125 µm), or 0.004" (100 µm).
o Precisely aligned with optical registration.
o Pad sizes: 0.012" (300 µm), 0.010" (250 µm), or 0.008" (200 µm).
2. Advanced Microvia Structures
o Via-in-pad, offset, staggered, or stacked.
o Filled with non-conductive material or solid copper, then plated over for stronger reliability.
o Stacked microvias using the inverted pyramid routing technique for extremely fine-pitch BGAs (down to 0.25 mm).
3. High-Density Routing for Fine-Pitch BGAs
o Supports 0.8 mm pitch devices and below.
o Optimized routing for 0.5 mm, 0.4 mm, and even 0.3–0.25 mm micro-BGAs.

Advantages of HDI PCBs
 Reduced cost at high density: When compared to multilayer boards beyond 8 layers, HDI can be a cost-efficient solution.
 Better electrical performance: Shorter interconnections improve signal integrity and accuracy.
 Higher reliability: Robust via structures and strong interconnections.
 Improved thermal properties: Better heat dissipation for high-performance devices.
 Reduced EMI/RFI/ESD: Improved shielding and noise resistance.
 Greater design efficiency: Enables smaller, lighter, and more powerful electronic products.
