Description

Technical Field

[0001] The present invention relates to the field of connector manufacturing technology, in particular to a radio frequency test socket manufacturing technology and a preparation process thereof. Background Art

[0002] As an integral component of communications electronics, RF test sockets enable fast and stable testing of RF chips, helping to improve circuit measurement efficiency. The development of 4G and 5G has accelerated the iteration of consumer electronics products. The rapid growth of multifunctional modules and wearable devices has also fueled the development of RF test socket connectors. RF test sockets are now used in a wide range of communications devices, including mobile phones, computers, tablets, smartwatches, and home appliances. Smart devices place high demands on the miniaturization, stability, and reliability of RF test socket connectors.

[0003] Currently, most RF test sockets on the market utilize a production process that assembles hardware onto plastic parts. This hardware assembly process requires high product precision, resulting in poor precision and consistency in the assembled products. With the demand for smaller test sockets, the assembly process for ultra-small products has become even more difficult to achieve. Because the hardware terminals and plastic parts are not integrally constructed, their solder creep and flux prevention capabilities are poor. The gold plating on the terminals easily seeps into the gaps between the solder mask and the plastic parts, causing solder paste and flux to creep onto the solder mask and contact areas. This affects the terminal's lever arm elasticity and can lead to functional failure, making false measurements more likely and resulting in insufficient product reliability. Summary of the Invention
