Properties of Nelco PCBs

A Nelco PCB has excellent mechanical and thermal properties. It is suitable for applications requiring signal integrity and precise impedance control. The main properties of Nelco PCBs are:

● Assembly Compatibility With Lead-free Technology: Nelco materials can be used in assemblies that have a reflow temperature of 245°C. But, the reflow temp could increase to 260°C. This is contingent on the type of construction and design process.

● High and Loss Speed: Nelco PCB has a low dielectric constant and dissipation coefficient. Thus, it is able to be used with low distortion and rapid signal propagation. This is ideal for high-performance and high-frequency applications. This PCB is suitable for applications that fall within the 1-10GHz frequency range.

● Excellent Thermal Stability Great Thermal Stability: Nelco PCB boards provide excellent thermal stability. This is the reason for the capacity of Nelco material to withstand heat. The glass’s transition temperature can be greater than 210 °C.

● Conductive Anodic Filament (CAF) Resilient: This is what makes Nelco circuit boards suitable for digital and RF applications. It also provides an extended period of reliability for these applications.

● A wide Range of Constructions: The PCB is available in various designs. Furthermore, these designs vary from copper weights to glass designs. They are also available as a two mill system.

Factors That Impact Nelco PCB Performance

The performance and capabilities of Nelco PCB are influenced by various aspects.

Fiberglass Weave

Glass fibers are woven by manufacturers in order to create fiberglass panels. This aids in the production of fiberglass within the prepreg as well as the core.

In addition, manufacturers impregnate the panels with epoxy resin. The fiberglass weaves come available in various styles of glass depending according to the form of fiber utilized.

Nelco PCB’s dielectric constant will be steady if the weaving netting is rigid. This is why loose weaves will result in less stable Dk.

PCB Stack-up Design

This is another factor that could affect performance of Nelco PCB boards. A poorly-designed stack-up could impact the transmission of signals. In addition, it could affect the reliability and power delivery of the board. When making Nelco PCBs, it is crucial to consider stacking. Nelco PCB manufacturers use various different layers of prepreg that alternate as well as copper foil and the core.

The Temperature of Transition to Glass (Tg)

Nelco boards are susceptible to expansion and contraction as a result of temperature fluctuations. The speed of expansion or contraction depends on the CTE that is present in the Nelco PCB material. When selecting the Nelco PCB materials, look for one that has a high Tg that can sustain temperature cycles. Tg is the term used to describe what temperature PCB’s PCB resin is higher than glass.

Nelco PCB Laminate is frequently chosen by our European customers. We have therefore created a sufficient standard Nelco PCB laminate inventory that is able to be delivered on time onto your Nelco PCB.

Nelco PCB Laminate is one of the most popular PCB laminates available in the PCB industry. Thus, this is definitely the best PCB raw material option that you can custom design yourself. We have enough stock to satisfy your Quick Turn and small and medium-volume Nelco PCB requirements.
