eMMC 패키지 기판 PCB 제조업체 | 20µm 라인/공간 | 4-Layer Ultra-Thin – UGPCB

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, 정제, IoT devices, and other consumer electronics. UGPCB, leveraging deep expertise in 고밀도 상호 연결 (HDI) PCB 제조, 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, 그리고 메인보드. 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 전문이다, miniaturized 인쇄 회로 기판 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) 인터페이스. Its design and manufacturing quality directly determine the signal integrity, 열 성능, and overall reliability of the final eMMC module.

디자인 하이라이트 & 주요 기술 사양

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

작동 방식 & 구조적 특징

작동 방식: The substrate acts as the internal “nervous system” and “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.

구조적 특징:

  1. 초박형 & 콤팩트: 0.21mm final thickness 그리고 11.5mm x 13mm unit size minimize space consumption.

  2. Advanced Core Material: Built on HL832NS, a high-performance laminate known for excellent thermal stability and low signal loss (낮은 Dk/Df), crucial for heat dissipation.

  3. Multi-Layer Architecture: 그만큼 4-layer stack-up (typically signal, 힘, 지면) optimizes signal paths, reduces crosstalk, and controls impedance.

  4. BGA Pad Array: The bottom side features a precise BGA pad layout for reliable surface-mount technology (SMT) assembly of the entire module onto the host motherboard.

Primary Application & 사용 사례

Primary Application: Core interconnection platform within EMMC 5.1 이상 chip packages.

일반적인 응용 프로그램 (사용 사례):

분류 & 재료 구성

Performance Advantages & 주요 특징

  1. 탁월한 신호 무결성: Controlled impedance and low-loss HL832NS material ensure stable high-speed data transfer.

  2. 높은 신뢰성: Stringent process controls and material selection guarantee long-term durability.

  3. Effective Thermal Management: The laminate’s good thermal conductivity aids in heat dissipation from the active dies.

  4. Tight Manufacturing Tolerances: 20µm line/space and 0.1mm micro-vias demonstrate 고급의 HDI PCB 조작 전문적 지식.

  5. End-to-End Solution: UGPCB provides collaborative support from substrate design review 그리고 PCB 제작 에게 빠른 PCBA 프로토 타이핑.
