Plug hole gold conductor pasteAs a key material for hard alloy electrical contacts, it has unique characteristics and advantages. This article will explore the characteristics of plug hole gold conductor paste from multiple perspectives, and use examples and data to demonstrate and analyze in depth.
The unique brown yellow paste like appearance reflects the uniqueness of the plug hole gold conductor paste. Compared to traditional black or gray conductor pastes, the brownish yellow appearance is more eye-catching and helps with accurate positioning during manufacturing and inspection during use. At the same time, this appearance also gives hard alloy electrical contacts a certain degree of recognition in appearance, providing support for product brand building and market promotion.
Viscosity is one of the important indicators for measuring the flowability of plug hole gold conductor slurry. After testing, the viscosity of the plug hole gold conductor paste is between 350 and 700 Pa · s, which gives it good adaptability and stability due to its moderate viscosity. Moderate viscosity can ensure uniform coating of the slurry and uniform formation of the film during both coating and sintering processes, thereby improving the electrical performance and mechanical strength of hard alloy electrical contacts.
The solid content is the amount of metal powder in the plug hole gold conductor slurry, which directly affects the conductivity of the slurry. After experimental research, the solid content of the plug hole gold conductor slurry is between 84% and 88%. This high solid content ensures the density and conductivity of the metal powder in the slurry, thereby ensuring the conductivity and reliability of the hard alloy electrical contacts.
Fineness is an important indicator for evaluating the particle size of plug hole gold conductor paste powder. After testing, the fineness of the plug hole gold conductor slurry is less than 15 μ m. This fine powder can ensure the uniformity and stability of the slurry, and reduce the differences in electrical contact performance caused by uneven powder particle size. At the same time, fine powders are also beneficial for the uniform formation of thin films, improving the surface quality of hard alloy electrical contacts.
Dilution is one of the important means to adjust the concentration of plug hole gold conductor paste. As a ready to use product, the plug hole gold conductor paste can be used without the need for diluent, which greatly facilitates the production and manufacturing process. If dilution is required, it is recommended to use turpentine and add no more than 5% by weight. Appropriate diluents and dilution ratios can help regulate the flowability and film-forming properties of the slurry, further improving the manufacturing efficiency and performance stability of hard alloy electrical contacts.
Next, we will focus on exploring the firing film properties of plug hole gold conductor paste. The fired film thickness is one of the key indicators for evaluating film formation. Through experiments, the fired film thickness of the plug hole gold conductor paste is between 8-12 μ m. On the premise of ensuring electrical contact performance, a moderate film thickness is formed, which can ensure good current transmission and mechanical strength of hard alloy electrical contacts.
Square resistance is one of the important indicators for measuring the resistance performance of hard alloy electrical contacts. After sintering
Plug hole gold conductor thin filmIt has a low square resistance. According to experimental data, when the film thickness is 8-12 μ m, the square resistance is less than 5m Ω/□. This low square resistance ensures the conductivity and stability of hard alloy electrical contacts, which meets the requirements of high reliability electrical contacts in electronic devices and automotive fields.
