Isola PCB Manufacturing for High-Performance Applications
Isola PCBs are widely used in RF power amplifiers, satellite communications, electric vehicle inverters and medical diagnostic equipment where standard FR-4 material cannot meet performance requirements.
These Isola laminate materials enable complex routing patterns across multilayer PCB configurations while maintaining stable dielectric properties and thermal conductivity under extreme operating conditions.
Isola has been around since 1912 and now has 10 manufacturing sites and 3 R&D facilities worldwide.
WellPCB processes Isola PCB constructions with material characterization, stack up validation, and thermal modeling expertise in mind, whether you’re developing an Isola PCB for qualification testing or transitioning to volume PCB manufacturing.
Our Isola PCB manufacturer operations utilize specialized lamination equipment for processing Isola materials, including Isola FR408, prepreg materials, and copper clad laminates, with temperature-controlled curing, void-free bonding, and dimensional stability verification.
Isola PCB material specifications are validated through glass transition temperature testing before laminate bonding and verified post-processing through microsection analysis.
Components like dielectric material layers and etched laminate circuits are examined for defects and conformance.
Our Isola PCB Manufacturing Capabilities
Our Isola PCB manufacturer facilities process Isola laminate materials using controlled temperature lamination, precision drilling and validated thermal cycling for aerospace, automotive, and telecommunications applications.
We support multilayer PCB constructions of up to 64 layers using Isola 370HR and Isola FR408, along with high-performance material processing, including the integration of copper clad laminates and complete PCB assembly traceability.
We, as a leading Isola PCB manufacturer, fabricate PCB boards using vacuum lamination presses with temperature control of ±4°F (±2°C) and pressure regulation from 200 to 250 PSI, positioning prepreg materials between copper clad laminates with precise registration.
Laminate and prepreg materials are selected based on their glass transition temperature (Tg), coefficient of thermal expansion (CTE), and resin content to ensure PCB construction dimensional stability across operating ranges of -40°F to 302°F (-40°C to 150°C).
Layer-to-layer registration maintains tight accuracy through optical alignment systems and fiducial tracking, ensuring that Isola PCB trace routing used meets 3 mil line/space requirements for high-density interconnects.
Mechanical drilling operations use carbide tooling to achieve hole diameters from 6 mil to 250 mil (0.15mm to 6.35mm) with aspect ratios up to 25:1 on Isola material substrates (up to 12:1 on 370HR depending on board thickness and via size).
Laser drilling systems operate at UV wavelengths for microvia formation, with a minimum diameter of 3 mil (0.075 mm), maintaining positional accuracy within ±0.6 mil (±15 μm) for high density interconnect (HDI) applications on printed circuit boards.
Via processing includes plasma desmear at controlled power settings and chemical etching with permanganate solutions optimized for Isola PCB material resin removal and copper adhesion enhancement.
Isola PCB surface treatments use immersion processes with controlled bath chemistry: ENIG with 0.05 to 0.1 μm gold over 120 to 240 μm nickel, and OSP with 8 to 20 μm (0.2 to 0.5 μm) organic coating thickness.
Electroless nickel immersion gold (ENIG) processing maintains a bath pH of 4.5 ± 0.1 and a temperature of 190°F ± 4°F (88°C ± 2°C) for materials used in PCB manufacturing that require multiple reflow cycles.
Heavy copper electroplating achieves a finished thickness of 20 oz using current densities of 15 to 25 ASF, with plating uniformity within ±10% across PCB panel surfaces.
Controlled impedance manufacturing utilizes field solver modeling and maintains single ended impedance of 50Ω ± 5Ω and differential pairs at 100Ω ± 10% through dielectric thickness control of ±0.3 mil (±8%).
370HR Isola PCB constructions achieve trace width and spacing down to 3/3 mil, with a copper thickness variation of ≤ ±10% for Isola PCB applications requiring consistent signal propagation.
Time domain reflectometry (TDR) testing validates impedance performance across dielectric material layers with a measurement accuracy of ±2% for PCB design verification.
Component placement uses vision-guided systems with ±1 mil (±25 μm) accuracy, supporting PCB assembly of 01005 components, 8 mil (0.2mm) pitch BGAs, and 6 mil (0.15mm) QFP lead spacing on advanced PCB constructions.
In circuit testing (ICT) uses flying probe systems with 2 mil (50 μm) probe accuracy and fixture-based testers that can accommodate over 20,000 test points for comprehensive electrical validation of Isola substrates.
Automated optical inspection (AOI) systems operate at 0.4 mil (10 μm) resolution with machine learning algorithms detecting solder joint defects, component placement errors, and PCB fabricators quality deviations.
Thermal cycling testing subjects multilayer PCB applications to -85°F to 302°F (-65°C to 150°C) transitions with 15-minute dwell times and 500-1000 cycle validation per IPC-TM-650 Method 2.6.7.
Highly accelerated stress testing (HAST) operates at 266°F (130°C) and 85% relative humidity for 96 to 1000 hours, evaluating the long term reliability performance of Isola PCBs.
Salt spray testing, as per ASTM B117 standard, exposes PCB construction to a 5% sodium chloride solution for 48 to 240 hours, validating corrosion resistance for harsh environment deployment.
WellPCB is a Isola PCB manufacturer that creates flexible PCB circuits using polyimide materials with thicknesses ranging from 0.05-0.5 mm (Ultimate:0.5-0.8 mm) and layer counts of 1 to 4 layers (with a maximum of 5 to 8 layers), as well as copper weights from 0.33 oz to 2 oz, for PCB applications that require dynamic bending.
Isola PCB rigid-flex constructions combine flexible sections with rigid multilayer PCB areas, supporting panel sizes ranging from 0.4” × 0.6” (10 mm × 15 mm) to 16” × 29” (406 mm × 736 mm), using Isola prepreg materials for seamless transition zones.

What is Isola PCB?
An Isola PCB is a printed circuit board manufactured using laminate materials and prepreg materials developed by the Isola Group, a materials science company specializing in copper clad laminates for electronic applications.
Isola PCB material consists of dielectric material layers with copper foil bonded together using a specialized resin system of Isola PCB formulations that create the PCB construction. The material used in Isola PCB manufacturing includes epoxy resin systems and glass fabric reinforcement processed into copper clad laminates and dielectric prepregs for multilayer PCB production.
What are the Differences Between Isola PCB and FR-4 Material?
Isola PCB materials handle much higher temperatures (338°F vs 266°F), provide superior electrical performance with lower signal losses, offer better mechanical strength, and cost significantly more than standard FR-4 material.
FR-4 material is the basic, affordable PCB material for general electronics, while Isola material like 370HR is a premium, high performance material option with advanced resin systems for demanding applications.
Both materials use glass-fiber reinforced epoxy resin systems, but the materials used in Isola PCB are engineered variants designed for aerospace, automotive, and high frequency PCB applications where standard FR-4 material performance isn’t sufficient. Isola materials achieve glass transition temperatures up to 500°F and enhanced thermal conductivity compared to basic FR-4 material.
The electrical differences become important in high speed designs: Isola PCB materials show lower dielectric constants and dissipation factors at high frequencies, making them ideal for PCB applications requiring superior signal integrity. Standard FR-4 material remains the preferred choice for cost-sensitive projects due to its significantly lower cost and wide availability.
| Property | Isola PCB Materials | FR-4 Material |
|---|---|---|
| Material Type | Premium high-performance material from Isola | Standard epoxy fiberglass laminate material |
| Glass Transition Temperature | 338°F to 500°F (170°C to 260°C) | ~266°F (130°C) |
| Thermal Performance | Superior heat resistance (Isola 370HR) | Basic thermal performance |
| Electrical Properties | Better signal integrity, lower loss | Good for general use |
| Dielectric Constant | 2.2 to 4.6 (varies by Isola material) | ~4.2 |
| Applications | High frequency PCB, aerospace, automotive | General electronics, consumer products |
| Signal Loss | Much lower for the materials used in Isola PCB | Higher loss at high frequencies |

Isola PCB Manufacturer FAQs
What triggers outgassing in Isola dielectric materials?
Outgassing in Isola material occurs from residual moisture in prepreg materials, incomplete curing of Isola PCB’s resin system, and volatile compounds trapped during processing. WellPCB minimizes this through proper pre-bake cycles and controlled humidity during Isola PCB fabrication.
Can you mix different Isola materials in the same multilayer PCB?
Yes, multilayer Isola PCB constructions can combine different types of Isola materials like Isola 370HR and 408HR in the same stackup. PCB fabricators must ensure compatible thermal expansion coefficients and cure temperatures when mixing materials used in Isola PCB to prevent delamination during PCB construction.
What's the maximum aspect ratio you can drill in Isola 370HR material?
We achieve aspect ratios up to 12:1 in 370HR Isola PCB constructions using specialized carbide tooling optimized for Isola material characteristics. PCB fabricators must adjust drill speeds and feed rates for Isola PCB material to prevent smearing and ensure clean hole walls in multilayer Isola PCB applications.
How do you prevent copper peel during Isola PCB etching?
As a reliable Isola PCB manufacturer, we use modified etching parameters and controlled etchant chemistry to prevent copper peel in Isola material.
Etched laminate processing requires specific temperature control and post-etch treatments for Isola PCB’s resin system to maintain strong copper adhesion in materials used in Isola PCB while achieving precise trace geometries for high-performance PCB designs.
