Glass Transition Temperature (Tg)
The thermal properties of the resin system are characterized by the glass transition
temperature(Tg), which always is expressed in °C. The most commonly used property is the
thermal expansion.When measuring the expansion versus the temperature, we can get a curve
as shown in followingpicture. The Tg is determined by the intersection of the tangents of the flat
and steep parts of theexpansion curve. Below the glass transition temperature, the epoxy resin
is rigid and glassy. Whenthe glass transition temperature is exceeded, it changes to a soft and
rubbery state.
For the most commonly used types of epoxy resin (FR-4 grade), the glass transition temperature
is in the range 115-130°C, so when the board is soldered, the glass transition temperature is easily
exceeded. The board expands in the Z-axis direction and stresses the copper of the hole wall.
The expansion of epoxy resin is about 15 to 20 times greater than that of copper when exceeding
Tg.This implies a certain risk of wall cracking in plated-through holes, and the more resin around
the hole wall, the greater risk. Below the glass transition temperature, the expansion ratio between
epoxy and copper is only three times, so here the risk of cracking is negligible.
