Introduction to RAYPCB and Multi-layer PCBs
RAYPCB, a leading printed circuit board (PCB) manufacturer, has recently announced an update to its standard stackup for multi-layer PCBs. This update aims to enhance the performance, reliability, and manufacturing efficiency of their PCB products. In this article, we will explore the significance of this update and how it benefits customers in various industries.
What is a Multi-layer PCB?
A multi-layer PCB is a printed circuit board that consists of three or more conductive copper layers laminated together with insulating material. These layers are interconnected through vias, which are small holes drilled through the board and plated with conductive material. Multi-layer PCBs offer several advantages over single or double-layer boards, including:
- Increased circuit density and complexity
- Improved signal integrity and reduced electromagnetic interference (EMI)
- Better heat dissipation and mechanical stability
- Reduced overall board size and weight
RAYPCB’s Commitment to Quality and Innovation
RAYPCB has been providing high-quality PCB solutions for over a decade, catering to customers in various sectors such as telecommunications, automotive, industrial, and consumer electronics. The company’s success can be attributed to its commitment to continuous improvement, advanced manufacturing capabilities, and customer-centric approach.
By updating its standard stackup for multi-layer PCBs, RAYPCB demonstrates its dedication to staying at the forefront of PCB technology and meeting the evolving needs of its customers.
Key Features of RAYPCB’s Updated Standard Stackup
Optimized Layer Configuration
One of the primary aspects of RAYPCB’s updated standard stackup is the optimized layer configuration. The new stackup incorporates a strategic arrangement of signal, power, and ground layers to maximize signal integrity and minimize noise and crosstalk.
| Layer | Function |
|---|---|
| Top | Signal |
| L2 | Ground |
| L3 | Signal |
| L4 | Power |
| L5 | Signal |
| L6 | Ground |
| Bottom | Signal |
This configuration ensures that critical signals are shielded by adjacent ground planes, reducing electromagnetic interference and improving overall signal quality. The power layer is strategically placed near the center of the stackup to provide a stable and low-impedance power distribution network.
Enhanced Material Selection
RAYPCB has carefully selected the materials used in its updated standard stackup to optimize performance and reliability. The company now uses high-quality, low-loss dielectric materials that offer excellent electrical properties and thermal stability.
| Material | Dielectric Constant | Dissipation Factor | Thermal Conductivity (W/mK) |
|---|---|---|---|
| FR-4 | 4.5 | 0.02 | 0.3 |
| Isola 370HR | 3.7 | 0.01 | 0.4 |
| Rogers 4350B | 3.5 | 0.0037 | 0.6 |
By using these advanced materials, RAYPCB can deliver PCBs with lower dielectric losses, improved thermal management, and better overall performance, especially at higher frequencies.
Improved Impedance Control
Impedance control is crucial for maintaining signal integrity and ensuring proper functioning of high-speed circuits. RAYPCB’s updated standard stackup incorporates stricter impedance control measures to meet the demanding requirements of modern electronic devices.
The company now offers tighter tolerances on controlled impedance traces, with a typical tolerance of ±10% for single-ended traces and ±5% for differential pairs. This level of precision is achieved through advanced manufacturing processes, such as fine-line etching and controlled dielectric thickness.
Enhanced Via Technology
Vias play a critical role in multi-layer PCBs, providing interconnections between layers. RAYPCB has implemented advanced via technologies in its updated standard stackup to minimize signal degradation and improve reliability.
-
Microvias: Microvias are small, laser-drilled vias that offer higher density and improved signal integrity compared to traditional mechanically drilled vias. RAYPCB now employs microvia technology in its standard stackup, enabling customers to design more complex and compact PCBs.
-
Filled and Capped Vias: To enhance the mechanical strength and thermal conductivity of the PCB, RAYPCB offers filled and capped vias as part of its standard stackup. Filled vias are plugged with a conductive material, while capped vias have an additional copper layer applied over the top and bottom surfaces. These techniques help to reduce thermal stress and improve the overall reliability of the PCB.
