WHAT IS A HIGH TG PCB? CHARACTERISTICS OF HIGH TG PCB?

Conduction


The heat generated by conduction cools down. It does this by placing the radiator directly on its heat source. In this way, it allows heat to flow from the source - similar to the way electricity flows in a system.

Radiation


Radiant heat dissipates by creating a direct path for electromagnetic wave separation.

Convection


Convective heat is dissipated by transferring heat to water or air. Therefore, it allows water or air to flow out of a specific area. A good example is the process of using a process or fan to push air across a surface while carrying away heat through the equipment.


ADVANTAGES OF USING HIGH TG PCB:

High TG PCB technology options


Under normal circumstances, the listed high Tg materials can be replaced by technically similar equipment. However, if you have specific requirements, you can communicate with our technical team.

CTE-z


This technical option shows the thermal expansion level of the substrate. Therefore, it represents the z axis. A lower CTE-z value works better than a higher Tg value - which means absolute expansion.

T260 - T288 value, Td


The T260 and T288 values represent the delamination time of the test material at 260oC and 280oC, respectively.


  • Q
    What electrical characteristics of high Tg circuit boards should you pay attention to?
    It is important to focus on moisture resistance, thermal decomposition and polymer transformation. In addition, attention should be paid to power requirements, delamination durability and heat resistance.
  • Q
    What precautions are required for temperature of high Tg board?
    For high Tg PCB manufacturing, the temperature of PCB is very important. Operating temperature/temperature area, including maximum temperature, extreme temperature, temperature durability, temperature environment, decomposition temperature and glass flow temperature. Welding temperature, temperature resistance and thermal temperature also affect product temperature. High temperature PCB manufacturing requires high temperature grade of high temperature and heat-resistant PCB.
  • Q
    How about the selection of high temperature resistant PCB materials?
    FR4 material/glass material is common for PCB substrate material selection. Raw materials also include rubber materials, flame retardant glass fiber reinforced epoxy resin materials.
  • Q
    How about the thermal management of PCB?
    The thermal management method is an important factor to be considered. Such as heat absorption, heat generation rate, heat grade, robust heat distribution, and thermal solutions. Thermal control of solutions, radiant heat and convective heat transfer are also important. In addition, you also need to pay attention to the methods of heating, conduction and extreme heating.
  • Q
    What else should we pay attention to when making PCB?
    First, you need to pay attention to the copper routing layer of PCB, such as single-sided PCB/single-layer PCB, double-sided PCB/double-layer PCB or multilayer PCB. Then the hole size, electronic components and wiring structure of the finished board. As for PCB functions, the following may affect electrical strength, physical properties, mechanical stability, thermal stability, power density design, reflective surface, pad lifting, thermal expansion rate and lead-free soldering. Due to the rapid development of electronic products, quality and service are paramount in PCB manufacturing.
