What is Shengyi Q160 PCB ?

If you have been searching for some reliable information on the Shengyi Q160 and Shengyi Q160 PCB, you are in the right place.

We will be discussing the characteristics, application areas, as well as other features of the Q160. Please continue reading as we explain the topic further.

What is Shengyi Q160?

Shengyi Q160 is a raw material for printed circuit boards, with great characteristics. Its thermal conductive performance is ≥0.7 W/m·K.

Furthermore, its tracking resistance is excellent at CTI≥600V. The Shengyi Q160 and Shengyi Q160 PCB are applicable for LED lighting.

What are the Properties and Characteristics of the Shengyi Q160?

Temperature of glass transition (Tg)

Shengyi Q160 has a Tg of 130. This is the temperature at which the PCB changes from its hard to its soft nature. This makes it a suitable material for printed circuit boards (Shengyi Q160 PCB). At this temperature, you can be sure of the printed circuit board’s mechanical stability all through the PCB’s operational life.

Decomposition Temperature (Td)

The Shengyi Q160 and its printed circuit board (Shengyi Q160 PCB) have a decomposition temperature of 360 degrees centigrade. Furthermore, this temperature is one at which the Shengyi Q160 material decomposes chemically. This means the Shengyi Q160 material loses a minimum of 5% of its mass.

Thermal Stress

 Also, the Shengyi Q160 and Shengyi Q160 PCB have a thermal stress of 60S with no delamination. This is achieved under the condition of 288 degrees centigrade and with the use of dip soldering.

Thermal stress is the creation of mechanical stress by a material’s temperature change. These stresses could cause plastic deformation or fracturing. This depends on other heating variables that include constraints and material types.

Coefficient of Thermal Expansion (CTE) at Z-axis

The CTE for the Z-axis at 50 to 260 degrees centigrade stands at 2.8%. This shows how much the Z axis of the Shengyi Q160 PCB will contract or expand when cooled or heated.

Volume Resistivity

Its volume resistivity after moisture resistance stands at 1.5 x 108 MΩ.cm. Furthermore, at E-24/125, its volume resistance stands at 2.8 x 106 MΩ.cm. This value aids in measuring the electrical resistance and insulation of the Shengyi Q160 PCB material. Once this value is high, then the circuit will experience a less movement of electric charge.

Surface Resistivity

Its surface resistivity after moisture resistance stands at 1.8 x 107 MΩ.cm. Furthermore, at E-24/125, its surface resistivity stands at 3.5 x 106 MΩ.cm. At this value, you can measure the insulation or electrical resistance of the Shengyi Q160 PCB material. Furthermore, it is affected by temperature and moisture.

Dissipation Factor

The Shengyi Q160 and Shengyi Q160 PCB material has a dissipation factor or loss tangent of 0.013. This value indicates the power that was lost as a result of the material.

When the dissipation factor of a material is low, it means that less power is lost. It is proportionate with frequency; this means that when there is an increase in frequency, it also increases.

Dielectric Constant

The Shengyi Q160 and Shengyi Q160 PCB material has a dielectric constant of 5.1. This value depends on the frequency. This means that it drops as frequency increases.

Also, this value is significant for impedance considerations and signal integrity. These factors are very significant for electrical performance of high frequency.

Benefits of the Shengyi Q160 PCB Material

You can enjoy several benefits when you use the Shengyi Q160 for your printed circuit boards.

Water absorption is at a low rate

The Shengyi Q160 PCB has a Tg of 130. This means that they function effectively in applications carrying much moisture. You can also be sure that water will not gain easy entrance into the PCB.

Its insulation properties are high

When insulating the Shengyi Q160 PCB, you will not have any problems. This also means you don’t have to be bothered about electric current leakage. Why this is so is because it has a temperature of glass transition at 130 and due to this, its insulation properties are high.

Its Arc resistance is high

With its Tg at 130, it possesses great insulation abilities. This helps in sustaining the discharges of the surface. With a current of at least 10 ma, this means that its arc resistance is high. Its arc resistance stands at 130s. This takes place most especially when there is neither electrical nor structural damages.

What Testing Techniques can we use for the Shengyi Q160 PCB Material?

Three major techniques are applicable when you want to test the Shengyi Q160 PCB material. These are thermal as well as dynamic mechanical analysis, and lastly, the differential scanning calorimetry.

Thermal Mechanical Analysis

This has to do with measuring the coefficient of thermal expansion of polymers during the test. In addition, this is a mechanical approach that uses heating and also measures your test samples. This is what it then makes use of to calculate the coefficient of thermal expansion. Note that you don’t have to use this method when using amorphous polymers. Why? Because the polymers’ heating will occur excessively

Dynamic Mechanical Analysis

Note that this is a very sensitive technique that helps in the measurement of a material’s responses when you apply stress. This also considers the way the Shengyi Q160 PCB material reacts to stress when you apply temperature at different ranges.

Differential Scanning Calorimetry

When testing for the Shengyi Q160 PCB material, it is very necessary to makes use of the most common technique. It should also be used traditionally.

For this testing technique, you’ll make use of a heat flow technique. Then you compare the supplied heat with the test samples.

In addition, you will discover a compared reference, which is also heated. This may reveal the right transition points to you. Using these reference transition points, you will be able to calculate the Tg.
