Related industries also put forward some standards for tungsten boat for semiconductor device, such as test methods, inspection rules, marking, packing, transportation and storage and other aspects.

After the preparation of the tungsten boat, it should be transported through strict inspection standards. Firstly, the test batches of the product must be the same types which have the same ingredients and produced in the same production process. When test products, people should test them seriously in accordance with the standards to ensure that products meet in all aspects of the standards requirements. Within two months of receipt of the product, the demand side should check products in accordance with the standards. If there exist some problems which do not meet the standards, customers can communicate with suppler.

The inspection for chemical composition of tungsten boat must be analyzed in the chemical composition of a sample in each batch of material. In the case of non-compliant, then the docimaster should analyze chemical composition of the sample, and then averaging it. If it still cannot meet the standards, it is determined that this batch of tungsten boat unqualified. Tungsten boat density test can be taken the same way to the test of the chemical composition. Tungsten boat specifications and surface quality should be one hundred percent inspection.

When packing the qualified tungsten boat. Every 10 wrapped in brown paper, in order to prevent the tungsten boat surfaces from being scratched or breaking. Then ut it into a plastic bag, 20 bags for a box, 4 boxes for a wooden case. Shock-proof scraps of paper should be filled with wooden case, and finally pack it up with iron sheet which can reinforce the wooden case. Inside the packaging boxes of products, material name, batch number, size, quantity, imprint of inspection department, inspectors stamp, date of production and name of the manufacturer should be indicated. Outside the packaging boxes of products, the name of the manufacturer, product names and specifications, quantity, and date of manufacture should be indicated.

In transit, pay attention to handle it. Although there are shock-proof scraps of paper in wooden case, but it still needs to prevent the product from being squeezed, crashed. Before shipping, it is better to have knowledge about the weather conditions, in case rain and snow which would cause product get cold. Therefore, the wooden cases should be place in a dry and ventilated shelves, the relative humidity must less than 65% without any alkalis, acids and other harmful gases.

Tungsten boat is formed by tungsten sheet through high-pressure tungsten which has a good electrical conductivity, so it is widely used in kinescope, mirror making, toys, household appliances, mobile phones, electrical enclosure and other electronics industries. In recent years, tungsten boat for semiconductor devices has also been given considerable attention by the public. Semiconductors are crystalline or amorphous solids with distinct electrical characteristics, using special electrical characteristics to complete the specific functions of electronic device. Therefore, related industries develop the relevant standards for tungsten boat for semiconductor devices. The followings include brands, models, specifications, technical requirements, test methods, inspection rules, mark, packing, transportation and storage.

Grades of tungsten boat can be named as WZO in according with the chinese phonetic alphabet "wolfram" and "boat". Tungsten boat models can be express as "V" and "U", different types of each model use the Roman numerals Ⅰ, Ⅱ, Ⅲ to represent. Tungsten boat specifications should be express in number in the format "- the wall thickness of the boat - the boat width." Applications should correspond to the marks and models. For example, WZO-V-Ⅰ-02-17, its brand is represented by WZO, V-type non-pressure side with 0.3mm tungsten boat wall thickness, 15mm tungsten boat width. Except that, the surface quality of tungsten boat should always keep in a clean condition, the color is silver-white metallic luster without any cracks, stratification, lack of edge and other defects. All parts of the tungsten boat cannot have glitches. Performance of tungsten plate used by tungsten boat should accord with the national GB3875 requirement. Using the accuracy of 0.02mm caliper and 0.01mm micrometer to measure tungsten boat size, according to national standard GB4196 tungsten boat standards. The weight of tungsten boat should be weight in a balance with a 0.2g sensibility of balance. If the chemical composition of tungsten boat is qualified, it is no need for measuring the melting point.

With the rapid development of tungsten boat for semiconductor devices, the threat of environmental pollution of tungsten boat is also rising. Tungsten compounds such as tungsten carbide dust, tungsten oxide, tungsten carbide, and tungsten boat have a great impact on health which would cause inflammation of eyes or skin and some respiratory diseases such as asthma, if people deal with it for a long time.
