How to Protect Ventec Vt47 from Heat Effects
Just like every other problem associated with the performance and quality of circuit boards. Everything still comes down to design. During a PCB design, it is crucial to consider the performance properties in a vacuum. Furthermore, designers need to ask about the stability of these properties under temperature.
If a circuit board will be exposed under a high-temperature application, there is a need to pass unstable and dependable materials at higher temperatures. Therefore, designers need to understand the relative thermal index (RTI) of a PCB material. According to this measure, there is a maximum temperature a particular PCB material can be subjected to in order to avoid any negative impact on performance or change the properties of the material.
The maximum operating temperature (MOT) is another rating PCB designers need to consider. MOT describes the maximum temperature at which a circuit in a PCB configuration can manage without any negative impact on properties or performance. Generally, it is advised to consider temperature effects during PCB design and manufacturing to make things much easier.
Using the appropriate laminate for a circuit board can protect it from high heat and enable the board to retain the properties needed to effectively function. There are several ways to protect your PCB laminate from heat effects. This involves considering the above mentioned properties.
