What is the Isola IS415 PCB Material?
The Isola IS415 PCB Material sets a high industry standard for epoxy materials with a high thermal performance. Also, it works great for designs that require a signal integrity that is high.
The engineering of this product is to meet the high demands of the lead-free multiplayer PCB assembly. Also, it focuses on delivering CAF resistance, thereby having a strong IST result. Furthermore, it maintains fr-4 processing.
In addition, the Isola IS415 PCB Material offers superior thermal and chemical performance as well as a great electrical performance and consistency of the product.
The attributes of this product includes a density interconnect that is high, thermal reliability that is high and a high speed digital. Furthermore, the market applications of the Isola IS415 PCB Material include computing and peripherals.
What are the Features of the Isola IS415 PCB Material?
Below are the major features of the Isola IS415 PCB Material.
The Isola IS415 PCB Material is CAF resistant. CAF here stands for conductive anodic filament. This means that this material has the ability to prevent the printed circuit board from going into the failure mode. CAF occurs whereby a salt (conducting), which contains copper can start forming in the printed circuit boards. This could cause the PCB to fail.
The Isola IS415 PCB Material also has the UV blocking feature. This means that material has the ability to block the harmful rays of the sun. Also, this is because the material can absorb UV radiation.
Furthermore, the Isola IS415 PCB Material is compatible with lead-free assembly. This means that this material can work with lead-free assembly to prevent any use of hazardous materials. Explaining further, it means an assembly that doesn’t make use of lead all through the manufacturing process.
High thermal reliability
What this feature means is that the Isola IS415 PCB Material can survive all through the assembly of the printed circuit board without any defect like delamination or blisters. Also, it is reliable in the operation environment all through the lifetime of the product. Both aspects of thermal reliability show the reliability of this printed circuit board material.
Also, the Isola IS415 PCB Material features ADI fluorescence. This is another reason why pcb engineers love this pcb material.
The Isola IS415 PCB Material is RoHS compliant. This means that this material has undergone tests for banned substances. This is usually conducted by independent authorities, and the test will reveal that the levels of those substances are less than the required RoHS threshold.
What are the Properties of the Isola IS415 PCB Material?
Below are the main properties of the Isola IS415 PCB Material
Low Temperature for Glass Transition
This is denoted as Tg. This helps in measuring the temperature whereby a printed circuit board material changes into a rubber-like state from its solid state. The property helps in contributing to the board’s thermal performance. The Tg of Isola IS415 PCB Material is 200 degrees Celsius.
High Decomposition Temperature
The Td of the Isola IS415 PCB Material is 370 degrees centigrade at a weight loss of 5%. Decomposition temperature helps in measuring the temperature whereby the Isola IS415 PCB Material decomposes chemically. Furthermore, it is very ideal for a printed circuit board material to have a decomposition temperature that is above 320 degrees Celsius.
Coefficient of Thermal Expansion (CTE)
The CTE value specifies the amount of contraction or expansion to expect when you cool or heat the material. Before Tg, the Isola IS415 PCB Material has a CTE of 45 ppm/°C. Furthermore, for post Tg, it has a CTE of 240 ppm/°C. Also, during total expansion that falls between 50 – 260 degrees Celsius, it has a typical value of 2.8%.At the X and Y axis, the coefficient of thermal expansion stands at 13 ppm/°C before Tg.
Thermal conductivity has to do with the rate whereby the transfer of heat from a source occurs to a cooler region in the material. The thermal conductivity of the Isola IS415 PCB Material is 0.4 W/m·K.
Dielectric constant (Dk)
The dielectric constant of the Isola IS415 PCB Material varies. At 1 GHz, 5 GHz, and 10 GHz, it has a dielectric constant of 3.71. Furthermore, at 2 GHz, it has a dielectric constant of 3.72, while at 100 MHz, it has a dielectric constant of 3.75.
However, generally, the material has a dielectric constant of 3.72. The dielectric constant has to do with the ability of the material to store charges.
Dissipation Factor (Df)
The dissipation factor of the Isola IS415 PCB Material varies. At 100 MHZ, the value is 0.0107, while at 1 GHz, its value is 0.0131. Furthermore, at 2 GHz, it has a value of 0.0120. At 5 GHz, the Df is 0.0127, while at 10 GHz, it has a value of 0.0125.
However, generally, the material has a dissipation factor of 0.0120. This value reveals how the Isola IS415 PCB Material will perform when used in different applications. This material has a low dissipation factor. This means that its insulating system is very efficient.
As we have explained in this article, it is clear that the Isola IS415 PCB Material possess great qualities. It will also serve different PCB needs. Please if you have any questions, feel free to reach out to us
