As a professional enterprise in the field of environmental test equipment, SANWOOD Technology helps semiconductor companies accelerate the exposure of potential defects with its high-precision environmental simulation technology, providing a important guarantee for the long-term stability of chips.

Semiconductor Industry Pain Points

Integrated Circuit (IC) Chip

IC chips are widely used in processors, memories, logic devices, etc. Their reliability directly affects the stability of electronic equipment.

Test item:

High and low temperature storage test: evaluate the stability of the chip at extreme temperatures, test standards JESD22-A101, GB/T 2423.1/2.

Temperature cycling test: Simulate the thermal stress diurnal temperature or equipment switching on and off, test standard JESD22-A104.

Damp heat test: Evaluate the corrosion resistance of the chip in high humidity environment, test standard GB/T 2423.3.

Power semiconductor 

Power semiconductors are widely used in new energy vehicles, photovoltaic inverters, which need to withstand high voltage, high current and temperature changes.

Test items:

High temperature and high humidity bias test: accelerate assessment of failure modes in humid environments, test standard JESD22-a110, IEC 60749

Optoelectronic devices (LED, laser diode, etc.)

Optoelectronic devices are sensitive to temperature, and high temperature may cause wavelength shift or light attenuation.

Test items:

High temperature aging test: evaluate light attenuation properties, test Standard IEC 62047

Cold and thermal shock test: simulate sudden change of outdoor temperature, test standard JESD22-a106

Salt spray test: evaluate the corrosion resistance in coastal or industrial environment, test standard GB/t 2423.17
