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 following picture. The Tg is determined by the intersection of the tangents of the flat and steep parts of the expansion curve. Below the glass transition temperature, the epoxy resin is rigid and glassy. When the 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.

Founded in 2003, Bicheng Enterprise Limited is a professional PCB export enterprise. We have established a good relationship of cooperation with well-known enterprises in the same industry.

The factories have been ISO 9001-2008, ISO 14001-2004 and ISO/TS16949-2009 quality management system certified. Over the past 14 years, we have provided professional circuit board manufacturing solutions for more than 5000 companies worldwide.
