Process

High-TG PCB Manufacturing Process

The complete High-TG PCB manufacturing process is based on the design package that makes the circuit board in physical form. Following is the process of High-TG PCB which starts with design and ends with testing:

Step 1: Pre Production Engineering

According to the manufacturing data and requirements provided by the customer, our engineers will compare it with standards and capabilities to make sure compliance and conduct related checks.

Step 2: Photo Plotting

A laser photo-plotter can be used to plot a film for each individual layer. A laser photo-plotter is a tool used to create photo-tools for solder mask and silkscreen.

Step 3: Imaging and Develop or Etch

This process applies the primary images such as pads and traces onto the circuit board. Here is what to do in this step: Apply photo imageable to the copper panels. Furthermore, image the panels using LSI. Etch off the whole exposed copper from the panel. Strip the remaining Dry Film and just leave the remaining copper pattern for the inner layers.

Step 4: Automated Optical Inspection

AOI basically inspects different layers of multilayer PCB before laminating all layers together. The optics compare the PCB design data to the actual image on the panel.

Step 5: Oxide

Oxide is a chemical treatment to inner layers before lamination for multi-layer PCBs. It is an important step to increase the roughness of copper to enhance the laminate bond strength.

Step 6: Lamination

To produce a multilayer PCB, different layers of epoxy-infused fiberglass are laminated together. The presser and heat cause the fiberglass sheet to melt and tightly join the layers together.

Step 7:Drilling

All PCBs need some holes to link copper layers, attaching components and mounting the PCB. We can drill holes using some advanced drilling systems. Furthermore, these have a design for the fast removal of chips in abrasive materials.

Step 8: Electroless Copper Deposition

After drilling, manufacturers deposit a thin coat of copper on the exposed surfaces of the panels chemically. Furthermore, they deposit a copper coat on the hole walls using electroless plating.

Step 9: Dry Film Outer Layer

After copper deposition, you must apply the outer layer images to prepare the panel for electroplate. So we can utilize a laminator machine to coat outer layers with the dry film. The dry film is a photo imageable material.

Step: 10 Plate

The electroplating process involves copper plating onto the conductive pattern. Plus on the hole walls of the PCB as well. The thickness of the plating is around 1 mil. After copper plating, you need to deposit a thin layer of tin plating.

Step 11: Striping and Etching

After completing the plating process on the panel, the dry film remains. Then, removing the uncovered area of copper by tin. So traces and the pads around the holes and copper patterns remain there. At last, remove the remaining tin that is covering holes and traces chemically.

Step 12: Surface Finish

It is the last and final chemical process to manufacture a multilayer printed circuit board. Solder mask covers almost all circuitry. So the surface finish prevents oxidation of the remaining exposed copper area.

High-TG PCB FAQ

The full name of TG used in PCB production is glasstransitiontemperature, which stands for glass transition temperature.

We provide a variety of high-TG PCB testing services, for example

  • ICT Test
  • Flying Probe Test
  • Function Test
  • X-ray Test
  • Laser Detection
  • AOI Inspection

The circuit board must be flame resistant and can only be softened at a certain temperature, not burned. The temperature point at this time is called the glass transition temperature (Tg point), which is related to the dimensional stability of the PCB board. The higher the TG value, the better the temperature resistance of the PCB.

The printed circuit board cannot withstand a thermal load no less than Tg 25 degrees Celsius, and if your product operates in a temperature range of 130 degrees Celsius or higher, your application will require a high Tg PCB.

Gateways, RFID, inverters, antenna boards, wireless boosters, contract manufacturing services, low-cost PLCs, embedded system development, embedded computer systems, AC power supplies.

As the Tg of the substrate increases, the characteristics of the printed board such as heat resistance, moisture resistance, chemical resistance, and stability resistance will be increased and improved.

To ensure the quality and safety, IBE has passed the audit and obtained many relevant certificates: ISO9001:2015, ISO14001, RoHS, and UL listed, World Class Quality and the Standards – IATF 16949:2016 Certified (for Automotive), ISO 13485:2016(for medical).

TG is generally divided into 3 grades, general TG, medium TG, high TG. Generally, the TG value is generally 130, 140, the medium TG value is generally 150, and the high TG value is generally above 170.

High-TG PCB : what is it and manufacturing

When it comes to electronic design, there is an entire universe of design variables and considerations to make to bring a device into life. Most of the important considerations have to do with the conductivity of the traces and the dielectric constant for signal integrity and proper isolation. Other conditions have to do with impedance matching and delay propagation for high-speed signals.

But, when you put a board on nature, the wear-off effect comes from the harsh environment (being it a thin-air, chemical environment, or a high temperature one) and the constant changes to the weather conditions, which are usually simulated on a HAL chamber. You could make a ceramic PCB to protect against high temperatures, but if you want to mass product such a product for a more commercial market, the prices will skyrocket, and there is the need to create or have a middle point that can withstand such conditions while still being practical in terms of economy and resistant.

What is High-TG PCB

A High-TG PCB comes into the game when you need to provide more temperature resistance than a typical FR4 made PCB. In essence, the concept for a high-TG PCB has to do with the term of glass transition temperature, or Tg, which could be understood as a “melting” point for a hard material, transforming its state from solid to burnished, vitreous material.

While a normal FR4 based PCB can hold up to 135°C, a high-TG PCB can start, depending on its grade, to withstand temperatures from 150°C and above, more on this below.

What’s the feature of High-TG PCB

As stated above, high-TG PCBs may have higher temperature endurance performance, which will be suitable for harsh environments in which temperature transitions happen consistently. The fact of heat resistance and glass transition endurance also prevents delamination, providing low thermal expansion due to the raw materials encountered on conventional high-TG PCBs.

Heat dissipation may happen through its conventional physical phenomena, conduction, convection and radiation, which enhance the thermal resistance of a high-TG PCB.

There might be different classifications for the TG endurance PCB types, but it is possible to provide some general subgroups, which can be separated as per the following chart.

MaterialTypeTemperature Resistance (°C)
CEM-1, FR4Standard Copper-Clad130-140
Composite CCLMiddle TG-PCB<150
ISOLA370, IT180, KB6167High-TG PCB170-225
Hydro-carbon ceramics, Teflon-basedUltra High-TG PCB220 ~ 260

Please note that the higher the temperature endurance, the more involvement of ceramic-based materials is introduced, more on this for cost calculations further.

More thermal endurance means more heat dissipation, and this is translated into more power density capabilities. Consider high-TG PCBs additional power density feature to save heat dissipation costs or enhance the power value reach for a finalized device.

One more feature that is important to mention is the RoHS compliance for the materials used in high-TG PCBs, which is important for lead-free process and product manufacturing.

What’s the application of High-TG PCB

Due to the constant revolution of the lighting industry, and due to the power capabilities of a high-TG PCB, it has become a replacement of metal core PCBs. Hence the greater balance in costs have provided a more economic approach for this market sector.

But the limitations of a high-TG PCB do not end there, these kinds of boards can be widely used in harsh engineering and industrial environments for endurance motor controllers with exceptional power dissipation factors and hence better energy dissipation techniques, welding and higher temperature material processing devices.

Robustness provided for the thermal resistance has also opened a way outside commercial use devices such as antennas or RFID gateways, including the usage of power supplies that can handle higher temperatures.
Some other safety and temperature critical devices are considered for the aerospace and military sector (missiles and radars) as well as the automotive and medical markets.

Finally, the high temperature endurance and power characteristics are very well related with computer performance. Hence, the usability of high-tg PCBs for dedicated motherboards for high performance computers such as supercomputers.

How to calculate a High-TG PCB cost

A high-TG PCB is no different to a conventional PCB in terms of cost. The difference will be related to the specific TG value / substrate that will be chosen for the manufacturing and the use of special stencils, if any are required. Mainly, the cost of a PCB is related with the following items:

1.Base Material
2.Number of layers
3.Dimensions
4.Quantity
5.Delivery format and cut
6.Thickness
7.Color
8.Surface finish
9.Via size
10.Use of high-end features (via covering, gold fingers, castellated holes)

When choosing your manufacturing partner, please verify that the pricing is not outrageous, and it is within a standard or average to that of the current market values.
