1.Tg 130 VS Tg 170

Firstly is the cost difference, the higher the TG, the more expensive the material will be.

TG 130 can be used for PCB in normal use at room temperature under 100C, and high TG170 material is required for high temperature application products or multilayer PCB.

If you want to make multilayers with blind & buried vias, that means you require several times of hot temperature lamination, then high TG material will be recommended.

considerations when using FR4 at maximum temperatures

2.Important considerations when using FR4 at maximum temperatures

A common mistake is to use the tG value to determine the operating temperature of the PCB. When choosing the correct FR4 PCB, a margin of at least 20°C should always be allocated. For example, a lower Tg FR4 of 130°C should have an operating temperature limit of 110°C.

As a PCB designer, you need to understand thermal regulation techniques in your design. The power conditioning module will generate heat and appropriate cooling techniques should be used.

Using heat sinks or thermal vias can help prevent hot spots from overheating, pushing the PCB beyond its limits.

3.What quality certifications are for TG130 material?

1) RoHS certification
2) REACH certification
3) UL certification
4) ISO certification
5) CE Certification
6) Flammability rating 94V0

How Does Tg 130 Compare to Tg 170?

Depending on your application specifications, you can either choose to use Tg 130 or Tg 170.

First, you should understand that Tg 130 and Tg 170 belong to two different groups.

You will classify Tg 130 under the Low Tg and Tg 170 under the high Tg group.

Implying that Tg 130 is among the lowest glass transitional temperatures that you can use.

On the other hand, Tg 170 is among the highest glass transition temperatures that you can refer to.

In addition to that, you can also note the difference in stability between Tg 130 and Tg 170.

Tg 170 has more stability in comparison to Tg 130 due to the fact that stability increases with increase in Tg.

At higher Tg, you can go on with the manufacturing of PCBs better as high temperature will not affect the materials.

Most importantly, you have to know the temperature requirement of the glass transition temperature.

With that knowledge, you will be in a better position to choose between Tg 130 and Tg 170.

Here are the three main techniques that you can employ to test the glass transition temperature.

Differential Scanning Calorimetry (DSC)

In case you are testing Tg of polymeric materials, you should consider using the most common and traditional technique.

You will employ a heat flow technique and then compare the test samples and the amount of heat you supply.

Apart from that, you will also compare it to a similarly heated reference that will determine the right transition points.

After that, you will calculate the glass transition temperature from the results of the reference points.

Thermal Mechanical Analysis (TMA)

Here, you will use the TMA method to measure coefficient of thermal expansion (CTE) of the polymers under test.

It is a mechanical approach that employs heating and measuring of test samples and then using it to calculate CTE.

In case you are testing amorphous polymers, then you should avoid TMA because it will heat the polymers in excess.

You should also note that the heating rate you will choose will also have an effect on the final glass transitional temperature.

Dynamic Mechanical Analysis (DMA)

You can also opt for the most sensitive technique which measures material responses to the application of stress.

It also looks at how the response of the materials to stress when you apply different temperature ranges.

You will be able to measure and separate the viscous and elastic components of the polymers alongside glass transition temperature.

Do You Have Surface Finishes that are Compatible to TG 130?

Absolutely, we have surface finishes that you can use on printed circuit boards with Tg 130.

You will use the surface finishes to improve the overall image of the PCBs with glass transition temperature of 130.

In other words, you can choose and use any board thickness that will suit your application requirements.

In standard boards, you will realize that the PCB thickness ranges between 0.2 to 6 millimeters.

You must, however, remember to maintain the glass transition temperature at 130 degrees centigrade.

How Does Molecular Structure of Materials Affect Tg 130?

Molecular structures of different materials have an effect on the glass transitional temperature.

A change in glass transitional temperature will affect the reliability, operation, as well as quality of PCBs.

In other words, change in temperature will have a profound effect on the molecular structure that make up the PCBs.

In response to the coefficient of thermal expansion, the molecular structure of the PCB will expand as Tg increases.

In case you go beyond Tg 130, you will have molecular stress on the molecular structure that may lead to micro-cracks.

Such cracks may go undetected during electrical tests on the molecular structure which ascertains material efficiency.

In worst cases, you may experience extreme failures on the PCBs if you exceed Tg 130 degrees centigrade.

What are the Properties of Standard Tg 130?

As soon as you get the idea of applying a PCB on a material, you must look at the properties of the material.

One of the most important properties that you should pay close attention to is the glass transition temperature.

On the same note of glass transition temperature, you should also look at the properties of glass transition temperature.

Here are some of the properties that define glass transition temperature of 130 degrees centigrade.

Resistance to High Temperatures

How Does the Standard PCB Tg Compare to Median PCB Tg?

In many cases, your choice of glass transition temperature will depend on the application requirements.

This gives you the opportunity to choose between the standard PCB Tg or the median PCB Tg.

Standard PCB Tg is the lowest form of glass transition temperature that you can have on your PCB.

Here, you will ensure that the glass transition temperature of the materials ranges between 130 to 140 degrees centigrade.

On the other hand, we have the median glass transition temperature which describes the medium range of glass transition temperature.

Median range of glass transition temperature which is about 150 degrees centigrade.

It is important to understand that the higher the PCB Tg, the greater the stability of the printed circuit board.

Implying that, standard PCB Tg is less stable in comparison to the High PCB Tg.

What is the Difference Between Standard PCB Tg and High PCB Tg?

On the same note, you may also have the standard PCB Tg or the high PCB Tg.

The low or standard PCB Tg ranges from 130 to 140 degrees centigrade.

On the flip side, you should know that any temperature above 150 degrees centigrade is high Tg.

According to the stability rule, an increase in glass transition temperature means and increase in stability.

In other words, high glass transition temperatures have greater stability than the standard glass transition temperature.

What is a Tg 130 Spot Thermal Camera?

Tg 130 spot thermal camera is a thermal imager that you can use for a number of different applications.

It will help you determine the right temperature of the device more accurately thus determining the Tg.

The device is light in weight, simple in nature, and also very easy for you to carry around and use.

Despite the benefits, it has a few limitations which include lack of proper image saving capabilities.

It also has a smaller screen size that forces you to strain while looking at the temperature results.

What is the Dielectric Constant of PCB at Tg 130?

Dielectric constants of materials usually change with changes in the glass transition temperatures.

Apart from that, the type of materials also plays a huge role in determining the glass transition temperature.

At Tg 130 degrees centigrade or at standard Tg, the dielectric constant ranges between 3.8 to 4.7.

Are the PCBs Halogen Free at Tg 130?

Well, you can choose to use halogen-free materials to manufacture PCBs with glass transition temperature of 130.

Most of the Tg 130 materials are usually not halogen free.
