In the booming landscape of high-performance computing, inteligencia artificial, 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 y sustrato CI soluciones, UGPCB introduces its premium 4-Layer DDR Substrate Board. Engineered with cutting-edge materials, it is specifically designed to carry high-performance memory chips (p.ej., DDR4, DDR5, LPDDR), serving as your reliable partner in the pursuit of ultimate speed and stability.

Descripción general del producto & Definición

A 4-Layer DDR Substrate Board is a High-Density Interconnect (IDH) printed circuit board designed for packaging and connecting Dynamic Random-Access Memory (DDR) papas fritas. 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, gestión térmica, and dimensional accuracy. This product from UGPCB is tailor-made to meet these stringent requirements.

Consideraciones críticas de diseño

1. Precise Impedance Control: Paramount for DDR PCB design, it minimizes signal reflection and distortion during high-speed data transmission.

2. Integridad de poder (PI): Dedicated power and ground plane design ensures clean, stable power delivery, reducing noise interference on critical signals.

   1. Integridad de señal (Y): Optimized routing using microstrip and stripline structures minimizes crosstalk and delay, forming the foundation for stable performance post-Asamblea de PCBA.

3. Gestión Térmica: The substrate material must exhibit excellent thermal properties to aid chip dissipation and ensure long-term reliability.

How It Works

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 (p.ej., in BGA packages).
