ISOLA IS420 PCB TG170 High Thermal Performance PCB

TG170 high-thermal-performance FR-4 material from ISOLA Company for high-temperature and reliability-driven multilayer PWB applications.

About ISOLA IS420

ISOLA IS420 PCB raw material is a high performance 170°C glass transition temperature (Tg) FR-4 system, for multilayer Printed Wiring Board (PWB) applications where maximum thermal performance and reliability are required.

ISOLA IS420 laminate and prepreg products are manufactured with a unique high performance multifunctional epoxy resin, reinforced with electrical grade (E-glass) glass fabric. The system provides improved thermal performance and low expansion rates compared to traditional FR-4 while retaining FR-4 processability.

In addition to superior thermal performance, the mechanical, chemical and moisture resistance properties all equal or exceed traditional FR-4 materials. The IS420 system is also laser fluorescing and UV blocking for maximum compatibility with AOI systems, optical positioning systems and photoimagable solder mask imaging.

Frequently Asked Questions

1. What is ISOLA IS420?

ISOLA IS420 is a TG170 high-thermal-performance FR-4 PCB material supplied by ISOLA Company. It targets high-temperature and reliability-driven multilayer PWB applications where standard FR-4 is not enough.

2. What are the key thermal and electrical properties?

Per the source page: Tg 170°C, Td 350°C, Dk 4.04 and Df 0.021. Note the page does not state the test frequency for Dk/Df, and does not publish CTE, T260/T288, thickness or water absorption.

3. Which industries use ISOLA IS420?

The source page lists Aerospace & Defense, Automotive & Transportation, Medical & Instrumentation, and Networking & Communications, plus IC-test / gold-finger applications.

4. How does ISOLA IS420 compare with standard FR-4?

It offers a higher Tg (170°C vs ~130–140°C), higher Td (350°C), and a balanced Dk/Df while staying FR-4 process compatible. See the comparison table above for a side-by-side view.

5. What files should I send to get an ISOLA IS420 PCB quote?

Send your Gerber files (RS-274X / ODB++) and BOM, plus stack-up requirements (layer count, finished thickness, surface finish, impedance if needed). Andwin provides a free DRC / DFM review before production.

6. What are the lead time and minimum order quantity (MOQ)?

Lead time and MOQ depend on your stack-up, layer count and order volume. Please confirm the exact figures with our sales team when you send the inquiry, so we quote against your real project rather than a generic number.
