eMMC PCB Package Substrate Product Overview

In today’s data-centric world, the performance and reliability of embedded storage are critical. EMMC (embedded MultiMediaCard) serves as the core storage unit in smartphones, tabletas, IoT devices, and other consumer electronics. UGPCB, leveraging deep expertise in Interconexión de alta densidad (IDH) fabricación de PCB, offers specialized eMMC Package Substrate PCBs. Designed with HL832NS material in a 4-layer, ultra-thin configuration, this substrate is the essential platform for high-speed, stable electrical interconnection between the memory controller, NAND flash dies, y el tablero principal. It is the optimal solution for developing next-generation compact, high-capacity storage modules.

What is an eMMC Package Substrate PCB?

An eMMC Package Substrate PCB is a specialized, miniaturized placa de circuito impreso used internally within an eMMC chip package. It serves as the core interposer, providing the electrical connections and physical support between the storage controller silicon die, the NAND flash memory dies, and the external Ball Grid Array (BGA) interfaz. Its design and manufacturing quality directly determine the signal integrity, rendimiento térmico, and overall reliability of the final eMMC module.

Destacados de diseño & Especificaciones técnicas clave

To meet the stringent demands of eMMC chips for high bandwidth and miniaturization, UGPCB’s eMMC substrate focuses on these critical design parameters:

• High-Density Routing: Supports ultra-fine circuitry with minimum line width/space of 20µm.

• Micro-Via Capability: Características minimum via diameter of 0.1mm for high-density I/O fanout.

• Stable Lamination: 4-layer construction with a controlled total thickness of 0.21mm, balancing electrical performance and mechanical strength.

• High-Reliability Surface Finish: Oro suave (ACEPTAR) plating provides an oxidation-resistant, low-resistance surface for reliable wire bonding or flip-chip attachment.

• Precise Solder Mask: PSR-4000 AUS308 solder mask offers excellent insulation and chemical resistance.

How It Works & Características estructurales

How It Works: The substrate acts as the internal “sistema nervioso” y “power grid” of the eMMC module. Its conductive traces and micro-vias route command signals from the controller to the NAND flash dies and return data. Dedicated power and ground planes ensure stable, low-noise power delivery.
