Taconic CER-10 PCB 2-layer 25mil 0.635 mm DK10 Immersion Gold Black Legend

Taconic CER-10 PCB 2-layer 25mil 0.635 mm DK10 Immersion Gold Black Legend

Product Overview

This product is a precision-engineered, double-sided Printed Circuit Board (PCB) fabricated on the advanced CER-10 organic-ceramic laminate. Designed for demanding high-frequency and microwave applications, this board combines exceptional electrical performance with robust mechanical reliability in a compact form factor. With a controlled dielectric constant (Dk) of 10 and an ultra-low dissipation factor (Df), it ensures minimal signal loss and stable impedance characteristics at microwave frequencies. The 25mil (0.635mm) thick CER-10 core provides excellent dimensional stability and interlaminar bond strength. Featuring a high-quality Immersion Gold (ENIG) surface finish on the copper traces, it offers a flat, solderable, and wire-bondable surface, ideal for sensitive components.

Core Material: CER-10 Laminate

This PCB is built upon Taconic CER-10, a premier material from the ORCER family. It represents a fusion of advanced ceramic fill technology and PTFE-coated fiberglass expertise. Key attributes include:

1)Stable High Dk: A dielectric constant of 10 at 10 GHz enables effective circuit miniaturization.

2)Ultra-Low Loss: A dissipation factor of only 0.0035 at 10 GHz ensures superior signal integrity for high-frequency energy.

3)Exceptional Reliability: It boasts outstanding interlaminar bond strength and blister-resistant solder performance (withstands multiple solder reflow cycles).

4)Environmental Stability: Very low moisture absorption (0.02%) and a low Z-axis Coefficient of Thermal Expansion (46 ppm/°C) ensure reliable plated through-holes and stable electrical performance under varying environmental conditions.

5)Flammability Rating: Complies with V-0 per IPC-TM-650, enhancing safety.

Key Features & Benefits

Optimized for Microwave Performance: The high, stable Dk and low loss tangent are ideal for passive microwave components.

Enhanced Mechanical Robustness: Superior flexural strength and dimensional stability (CTE: X=13, Y=15 ppm/°C) ensure durability during assembly and in the field.

Reliable Assembly Surface: Immersion Gold finish provides excellent oxidation resistance, shelf life, and compatibility with fine-pitch SMT and wire bonding.
