Technical Field

[0002] As a core component of wireless communication equipment, radio frequency (RF) inductors need to be efficiently sorted, taped, and mounted through automated production lines. RF inductors with the same package size often correspond to different inductance values, which need to be quickly distinguished by marking. At the same time, high-frequency scenarios have strict requirements for controlling the signal loss of inductors. The marking material must avoid introducing additional dielectric loss and must withstand the high temperature of soldering to ensure reliability.

[0003] However, existing RF inductors lack a unified MARK marking, making it difficult for optical inspection systems to distinguish products with different inductance values ​​in the same package. During tape and reel packaging, positioning deviations can easily lead to low efficiency. Secondly, inaccurate tape and reel positioning reduces sorting and tape packaging efficiency, making it difficult to adapt to automated production lines. At the same time, it is difficult to quickly install and remove inductors, making maintenance inconvenient. Thirdly, conventional marking inks have a high dielectric constant, which increases high-frequency signal loss and is prone to carbonization and peeling during high-temperature soldering, affecting the stability of inductor performance and service life. Therefore, there is an urgent need for an RF inductor with double-sided MARK marking to solve the above problems. Utility Model Content
