Definition of Panasonic HEPER R-1755D

The Panasonic HEPER R-1755D is indeed a high reliability multilayer glass epoxy material that offers several desirable properties for PCB (Printed Circuit Board) applications. One of its notable features is its low coefficient of thermal expansion, which means that it exhibits minimal dimensional changes when exposed to temperature variations. This property is crucial for PCBs as it helps to ensure the stability and integrity of the circuitry, especially in environments with fluctuating temperatures.

Another important characteristic of the HEPER R-1755D is its high glass transition temperature. The glass transition temperature (Tg) refers to the temperature at which the material transitions from a rigid, glassy state to a more flexible, rubbery state. A high Tg is desirable for PCBs because it indicates that the material can withstand elevated temperatures without losing its mechanical strength or electrical properties. This is particularly important in automotive applications where components may be exposed to high temperatures generated by the engine or other heat sources.

The HEPER R-1755D is available in the form of a laminate, which is the main structural layer of the PCB, and the prepreg, which is a partially cured resin used to bond multiple layers of laminate together. The laminate provides the base material for the PCB, while the prepreg acts as the adhesive layer between the laminate and the copper foils or other conductive layers. The use of the R-1650D prepreg in conjunction with the R-1755D laminate ensures compatibility and optimal performance of the overall PCB structure.

Due to its high reliability and heat resistance, the Panasonic HEPER R-1755D material finds extensive use in automotive components. Automotive electronics often operate in demanding environments with temperature variations, vibrations, and other challenging conditions.
