What is Evaporation Boat

Evaporation Boats are ceramic components required for vacuum deposition of various types of metals e.g. aluminum, copper, silver etc. over various substrates.Two Component boat is longer lasting and of better quality. In three component boat, Aluminum Nitride is added to bring down the cost. But consequently, it is lower in life and quality as well. Hence, users prefer 2 component boats to 3 component ones.Production of Evaporation Boats is very expensive, involving heavy, costly machinery, raw materials and running energy costs. Also it is protected by patent laws. Therefore, very few companies in the world are producing it.

Types of Evaporation Boat

Ceramic Evaporation Boat
Ceramic evaporation boat is an evaporation container widely used in vacuum evaporation technology to melt various metal materials, such as aluminum, zinc, etc. It is suitable for vacuum evaporation packaging materials, capacitor metallization coating, display coating, solar cell coating, hot stamping coating, anti-counterfeiting logo coating, reflective coating, paper making, textile aluminum plating and other industries. Can be professionally designed and customized according to customer requirements.

350 Evaporation Boat
350 Evaporation Boat mainly has two types: tungsten boat and molybdenum boat. Different types of evaporation boats are suitable for different coating needs.The size of 350 Evaporation Boat is usually 350mm, but this size may vary depending on different manufacturers and product models.350 Evaporation Boat is mainly used in university laboratories and vacuum coating factories. It can match various types of evaporation materials, such as metals, oxides, nitrides, etc.It has the characteristics with high purity, high temperature stability, good electrical conductivity and thermal conductivity, which make it have good performance in the evaporation coating process.

Ceramic Conductive Evaporation Boat
Ceramic Conductive Evaporation Boat are devices used for evaporative deposition of thin films. They are primarily made of ceramic material with a layer of aluminum film on the surface. These evaporation boats feature high electrical conductivity and thermal stability, allowing them to operate stably in high-temperature and vacuum environments. Ceramic Conductive Evaporation Boat are widely used in fields such as solar cells, flat panel displays, and thin-film coatings.

Special Shaped Evaporation Boat
The main feature of the special shaped evaporation boat is that its shape and size can be designed according to the specific coating process requirements to improve the evaporation efficiency and coating quality.Among the materials used to make special shaped evaporation boats, tungsten is a commonly used material. Tungsten has excellent properties such as high melting point, high vapor pressure, and high thermal conductivity, making it very suitable for making special shaped evaporation boats. In addition, there are some other materials that can also be used to make special shaped evaporation boats, such as titanium and molybdenum.

Some Information When You Use Evaporation Boat

Graphite Paper
Carelessly handling graphite transfer paper can lead to messy results. Make sure it remains in an area that will protect it, such as by taping several sheets together for multiple drawings or wrapping it in glassine and taping that in front of it for additional security.As graphite foil will transmit significant current, it must have an excellent purity of over 99% and compressibility. Low quality plumber grade graphite foil may contain additives like binders and resins which cause overheating and lack of conductivity; furthermore it should have a uniform cross section without impurities.

Aluminum Wire
Evaporation boat is ceramic components used for vacuum deposition of various metals- aluminium, copper etc.onto substrates by vacuum. They must be electrically conductive, resistant to high temperatures, and inert towards any molten metal; to meet this criteria mixed ceramics made up of two or three components are typically utilized.The shape of an evaporation boat has an effect on both the distribution and quality of metalization. Molten metal will move differently when placed in convex boats as opposed to flat or concave ones, as will speed of metalization; faster metalization leads to thinner coatings with reduced homogeneity.

Copper Electrodes
Copper electrodes are essential components of an evaporation boat. As the source of current that heats aluminum, these electrodes must provide high resistance heating of the evaporation boat while still remaining resistant to high temperatures and inert against melting aluminum; mixed ceramics often meet this criteria.These electrodes can be created via CNC machining. Accurate part drawings with tight tolerances are essential in this process, serving as the negative shape to be machined-this ensures proper fitting and reduces waste when CNC milling the copper EDM electrode.

Vacuum Chamber
Evaporation boat is ceramic components used for vacuum deposition of various metals like aluminum and copper onto substrates, as well as for electronic device manufacturing, photovoltaics and more. Their ceramic construction provides electrical conductivity while being resistant to high temperatures; two or three component versions may also be available.An outstanding metallurgical quality is crucial to the success of thin film coating processes, since substandard evaporation boats may lead to low wettability which could result in issues like spitting, puddle formation and pin holes in the final coating. To avoid such issues, two or three component evaporation boats with enhanced wettability should be used instead of just one-component ones.

These Industries Can't Do Without Evaporation Boats

Semiconductor Industry
Firstly, BN boats are widely used in the semiconductor industry. The material properties of BN boats determine that they are an excellent choice for the semiconductor industry, particularly for the growth of nitrides, oxides, and other materials. They can effectively prevent contamination and provide a clean and stable environment for the growth of semiconductor materials.

Ceramic Industries
Secondly, the metallurgical and ceramic industries also benefit from BN boats. These industries require high-temperature resistance, chemical resistance, and thermal shock resistance. BN boats are the perfect choice for these requirements. They can withstand high temperatures that range from 1000°C to 1800℃, making them ideal for the melting and casting of high-melting point materials like tungsten, molybdenum, and other alloys. Additionally, they can provide a stable environment for the thermal treatment of ceramics.

Which Shape of Evaporation Boat Is Best for Metallizing?

Boat Life
It cannot be stressed enough how important it is for the evaporation boat to have a long operational life while at the same time maintaining coating uniformity. A good evaporation boat's constituents will resist corrosion but also allow smooth and even spreading of molten metal.

Price
Going for low priced evaporation boat at the cost of boat life and quality of coating makes absolutely no sense. While you may feel happy on saving some money on the cost of the boat, you may actually be incurring huge electricity bills. Increase in machine down-time and overall cost of boats also goes up. On the contrary, going for very expensive boats also makes no economic sense.

Easy Availability
For roll-to-roll coaters, continuous and easy availability of evaporation boats is a necessity. Otherwise this leads to huge stock piles of inventory and blocking of lakhs of Rupees. Non-availability of boats has been known to bring the entire metallizing operations to a grinding halt.

Short lead time by the supplier
Operators of metallizers are often forced to place huge orders of evaporation boats many months in advance as the lead time of the supplier may be pretty long. This feels like a dagger dangling over the operator's head, to say the least. It makes good business sense if your boat supplier's lead time is short. That way, you don't have to wait for long periods of time for your next consignment of boats to arrive.

How to Choose Evaporation Boat

Resistivity
Resistivity is a measure of the resisting power of a specified material to the flow of an electric current.A boat with low electrical resistivity will readily allow electrical current to flow through it, thereby failing to heat up. On the other hand, highest electrical resistivity is limited by metallizer's power supply. Therefore, it is desirable that the boat be of optimum electrical resistivity so that it heats up slowly, allowing aluminum to melt on it and cause uniform coating.

Wettability of the boat
Simply put, this is a measure of how the molten metal (aluminum, in most cases) will behave when in contact with the ceramic boat. Better wettability of the boat will mean improved quality in coating. Impurities in the evaporation boat can lead to poor wettability. Molten metal not spreading evenly, puddle forming, spitting etc. are some of the issues we face when the boat is not wetted properly. Although high wettability is quite desired, it comes at the cost of the life of boat. In other words, very high wettability leads to lower resistance to corrosion. Therefore, an ideal evaporation boat will have balance between wettability and resistance to corrosion.

Resistance to corrosion
When aluminum liquefies on the boat, it starts reacting with boron nitride present in the boat and forms aluminum nitride and compounds of boride, thereby corroding the boat. With time, fissures, grooves and cracks form on the surface of the boat which results in premature failure of the boat. But if the boat is made with the sole purpose of resisting corrosion, it will hamper wettability. Hence, an ideal boat will have an optimum resistance to corrosion without affecting wettability.

Two Component boat / Three Component boat
Ceramic Evaporation boats are of two types- 2 component boat and 3 component boat. Two component boats are made up of Boron nitride and Titanium diboride. Three component boats also have Boron nitride, Titanium diboride plus Aluminum nitride to bring down the cost. The following chart shows the difference between the two.

Composition of Evaporation Boats

Basic Materials

Commonly used materials include zirconium silicate, boron oxide, boron nitride, aluminum oxide, and yttrium oxide, which are mixed with deionized water and polyvinyl alcohol as a binder.

Advanced Composites

Some boats utilize a combination of silicon nitride, titanium boride, and aluminum nitride, which enhances their semi-conductive properties and thermal stability.

Sintering Techniques

The preparation often involves pressureless sintering at high temperatures (1600-1750°C) to achieve optimal material properties.

Process of Evaporation Boat

Preparing the powders
First of all, the powder particles are brought down to the desired size through milling.

Blending of the raw materials
The powders are mixed together in the desired ratio and blended thoroughly for the sake of uniformity in the raw material.

Hot-pressing
The blended raw material is then hot-pressed at a very high temperature (More than 1500⁰C) with a pressure of more than 150 tons. This delivers a big block of ceramic.

Machining
The hot-pressed ceramic block is then cut into boats with a diamond cutter. Each boat is ground for a smooth finish and dimensional accuracy.A cavity is ground into each boat.

Quality control
Each and every boat is measured for resistivity. After final inspection, boats are packed for shipping.
