Lead the High-Speed Era: UGPCB’s 4-Layer DDR Substrate Board – The Superior Interconnect Solution for Your Core ICs
In the booming landscape of high-performance computing, intelligenza artificiale, and next-generation communication devices, every advancement in Double Data Rate (DDR) technology places stricter demands on PCB substrates. Leveraging deep expertise in high-end PCB manufacturing E Substrato del circuito integrato soluzioni, UGPCB introduces its premium 4-Layer DDR Substrate Board. Engineered with cutting-edge materials, it is specifically designed to carry high-performance memory chips (per esempio., DDR4, DDR5, LPDDR), serving as your reliable partner in the pursuit of ultimate speed and stability.
Panoramica del prodotto & Definizione
UN 4-Layer DDR Substrate Board is a High-Density Interconnect (ISU) printed circuit board designed for packaging and connecting Dynamic Random-Access Memory (DDR) patatine. It acts as a critical bridge between the chip and the mainboard, responsible for transmitting high-speed signals, distributing power, and providing stable mechanical support. Unlike standard PCB boards, DDR substrates demand near-perfect signal integrity, gestione termica, and dimensional accuracy. This product from UGPCB is tailor-made to meet these stringent requirements.

Considerazioni critiche sulla progettazione
-
Precise Impedance Control: Paramount for DDR PCB design, it minimizes signal reflection and distortion during high-speed data transmission.
-
Integrità del potere (PI): Dedicated power and ground plane design ensures clean, stable power delivery, reducing noise interference on critical signals.
-
Integrità del segnale (E): Optimized routing using microstrip and stripline structures minimizes crosstalk and delay, forming the foundation for stable performance post-assemblaggio PCBA.
-
-
Gestione termica: The substrate material must exhibit excellent thermal properties to aid chip dissipation and ensure long-term reliability.
Come funziona
The 4-Layer DDR Substrate connects the hundreds of micro-pins of a memory chip to the corresponding motherboard circuits via its precise internal layers. Its “sandwich” stack-up (Signal-Ground-Power-Signal) provides clear return paths for high-speed signals, effectively suppressing Electromagnetic Interference (EMI). The soft gold surface finish ensures a reliable, low-resistance solder joint with the chip’s solder balls (per esempio., in BGA packages).
