Product Description

2-Layer Kappa 438 PCB 1.6mm Thickness 1oz Cu, ENIG Finish

This 2-layer PCB uses high-performance Rogers Kappa 438 as its base material. It's a top-notch electronic part that mixes precise engineering with great functionality. Measuring 53mm x 36mm (±0.15mm), this PCB stands out in many uses because of its base material's unique traits, making it a solid pick for tough electronic projects.

Rogers Kappa 438 is a glass reinforced hydrocarbon ceramic system made for PCB substrates. It delivers excellent high-frequency performance and allows low-cost circuit production. As a low-loss material, it works with standard FR-4 processes. It has a UL 94 V-0 flame rating, works with lead-free soldering, and comes in standard thicknesses: 10, 20, 30, 40, 60 mil. Its dielectric constant (Dk) matches FR-4 norms, making it easy to upgrade existing FR-4 designs for better electrical performance.

Kappa 438 Features

Glass reinforced hydrocarbon thermoset base: This structure combines glass reinforcement for mechanical strength with a hydrocarbon thermoset matrix, striking a balance between durability and electrical performance, making it robust enough for various application environments.
Dk of 4.38 (matches FR-4 norms for easy design conversion): The dielectric constant aligns with FR-4 standards, allowing designers to seamlessly transition existing FR-4 layouts to Kappa 438 without major overhauls, streamlining the upgrade process.
Tighter Dk and thickness tolerance than FR-4 (more consistent performance): Compared to FR-4, its stricter tolerances mean less variation in dielectric properties and thickness across the board, ensuring signals behave predictably and circuits perform uniformly.
Low Z-axis CTE (42 ppm/ °C, good thermal stability): A low coefficient of thermal expansion in the Z-axis minimizes warping or delamination when exposed to temperature changes, enhancing the PCB's reliability in thermal cycling conditions.
High Tg ( >280°C TMA, stable at high temps): With a glass transition temperature above 280°C, it maintains its structural and electrical integrity even in high-temperature environments, suitable for applications with intense heat.
Thermal coefficient of Dk (-21 ppm/ °C from -50°C to 150°C, stable dielectric properties): The small change in dielectric constant over a wide temperature range ensures consistent signal transmission, critical for maintaining performance in fluctuating thermal conditions.
UL 94-V0 rated (flame retardant): Meets the UL 94 V0 standard, self-extinguishing quickly to prevent fire spread, adding a layer of safety in applications where fire risk is a concern.

Benefits

Easy to manufacture and assemble like FR-4 (lower complexity and cost): Compatible with standard FR-4 manufacturing and assembly processes, eliminating the need for specialized equipment or training, thus reducing production complexity and associated costs.
Simple to upgrade FR-4 designs for better performance (saves time and resources): Its similar properties to FR-4 allow straightforward conversion of existing designs, avoiding the need for full redesigns and saving valuable time and development resources.
Consistent circuit performance (reliable operation): Tighter tolerances and stable material properties translate to consistent circuit behavior, reducing the risk of performance variations and ensuring reliable operation in end products.
More design flexibility and better plated through-hole reliability (higher quality): Offers greater flexibility in design choices while improved plated through-hole reliability enhances the PCB's overall quality and longevity, even in demanding use cases.
Works with automated assembly (faster production): Compatible with automated assembly lines, enabling high-speed production and increasing manufacturing efficiency to meet large-scale demand.

Applications

Carrier Grade WiFi/LAA (stable high-performance wireless)
Small Cell and DAS (better signal coverage)
V2X Communications (reliable automotive links)
IoT (Smart Home, Wireless Meters - efficient data transmission)

In short, this PCB pairs Kappa 438's unique properties with precise engineering. It's reliable and efficient for many uses, making it a top choice for engineers and manufacturers needing a dependable PCB.
