Proper installation and maintenance are crucial to extending the service life of boron nitride evaporation boats in the electroplating industry, which can save labor and production costs for enterprises and improve economic efficiency.
Avoiding Moisture Contact: The boron nitride component in the boron nitride evaporation boat is prone to absorbing moisture, which can lead to evaporation boat explosion during heating as the moisture vaporizes. Therefore, it is imperative to ensure that the evaporation boat is kept free from water contact before and during use.
Installing with an Appropriate Incline: When installing the evaporation boat, maintaining a certain inclination (e.g., with the aluminum wire feeding end slightly higher) facilitates the flow of liquid aluminum to the end of the boat, increasing the spreading area of the liquid aluminum. This prolongs the life of the evaporation boat and enhances the uniformity of the coating. Additionally, the evaporation boat should be kept horizontally level in the transverse direction.
Preventing Contamination and Damage: Avoid touching the surface of the boat's trough to prevent contamination, as this can reduce the wettability of the trough's surface to liquid aluminum. Ensure that the length of the clamping section at both ends of the evaporation boat is appropriate to prevent extra heat generation at the clamps, while also ensuring uniform temperature distribution on both sides of the boat to prevent bowing.
