<span>High-TG PCB Advanced Circuits Specification</span>
</p>
<p class="MsoNormal">
<span>&nbsp;</span>
</p>
<p class="MsoNormal">
<span>The glass transition temperature of a
printed circuit board, referred to as "Tg", indicates the point at
which the PCB material will begin to transform. If the operating temperature
exceeds the designated Tg value, the board will begin to change from a solid to
a liquid state, which is likely to have an adverse effect on its ability to
function.</span>
</p>
<p class="MsoNormal">
<span>&nbsp;</span>
</p>
<p class="MsoNormal">
<span>Standard PCBs are manufactured with
materials offering a TG value of 140°C, which can withstand an operating
temperate of 110°C. While this may not be suitable for extreme-temperature
processes that are commonplace in applications such as automotive, industrial
or high-temperature electronics. In these situations, a PCB made from FR-4
material can often provide the best solution.</span>
</p>
<p class="MsoNormal">
<span>What Is FR-4?</span>
</p>
<p class="MsoNormal">
<span>&nbsp;</span>
</p>
<p class="MsoNormal">
<span>FR-4 is a grade designation for
flame-retardant fiberglass reinforced epoxy material. Thus, FR-4 PCB offers a
much greater level of resistance to heat than a standard PCB. FR-4 circuit
boards are divided into four classifications that are determined by the number
of copper trace layers found in the material:</span>
</p>
<p class="MsoNormal">
•<span> Single-sided PCB / Single-layer PCB</span>
</p>
<p class="MsoNormal">
•<span> Double-sided PCB / Double-layer PCB</span>
</p>
<p class="MsoNormal">
•<span> Four or more than 10 layers PCB / Multilayer PCB</span>
