Exceptional thermal shock resistance for semiconductor wafer processing.
Operating above 1,600℃ accelerates thermal degradation, reducing an evaporation boat’s service life by up to 50%.
Maintaining optimal operating temperatures between 1,500℃ and 1,550℃. This can maximize durability and stabilize vaporization rates, delivering superior film output per boat.
Higher resistance offers controlled heating and maximum evaporation boat service life.
Lower resistance enables rapid heating cycles.
Custom-calibrating precise resistance tolerances to your power equipment prevents electrical stress, stabilizing current draw for seamless, highly uniform vacuum metallization.
Higher electrical resistance. It enables smoother, more efficient heat distribution, reduces thermal shock during initial ramping, and preserves structural integrity.
It is typically caused by inconsistent electrical resistance, unstable temperature distribution, irregular substrate line speeds, or low aluminum purity.
BN-TiB2 composite ceramic evaporation boats offer superior chemical inertness, rapid self-heating, and exceptional thermal shock resistance. They ensure pristine layer purity, extended continuous operation, and up to 40% lower operational consumable costs.
On the contrast, graphite boats suffer from severe molten aluminum erosion, dust contamination, and short lifespans.
Prevent splashing by using an evaporation boat with precision-engineered cavity grooves and balanced thermal conductivity. Combining uniform resistance heating with high-purity (99.99%) aluminum wire promotes smooth metal wetting and even spreading, eliminating liquid splatter even during ultra-high-speed metallization runs exceeding 600 meters per minute.
Precision cavity designs and customized groove patterns expand the molten metal wetting surface and control liquid distribution across the evaporation boat. This optimizes heat transfer, prevents liquid pool overflow or splashing, and guarantees a steady, uniform evaporation rate across the entire substrate width for superior metallized film quality.
Store ceramic evaporation boats in their original vacuum-sealed packaging until immediate installation. If opened, store unused boats in a controlled constant-temperature and constant-humidity environment to prevent atmospheric moisture absorption.
Humidity exposure causes ceramic evaporation boats to absorb atmospheric moisture. When energized in a high-temperature vacuum chamber, trapped moisture rapidly turns to steam, triggering severe thermal shock, micro-cracking, unstable electrical resistance, and sudden structural failure.
