Description

Technical Field

[0001] This utility model relates to the field of electronic component packaging technology, and in particular to an electronic component packaging structure that facilitates installation and maintenance. Background Technology

[0002] Electronic components are the basic units that make up electronic devices and electronic systems. They have specific electrical characteristics and functions, and can process, control, transmit and store electrical signals. They are an indispensable part of the field of electronic technology.

[0003] Electronic component packaging structure refers to the structural form in which electronic component chips or bare dies are wrapped, fixed and electrically connected through specific processes and materials, so that they become components with specific shapes, sizes and pin arrangements.

[0004] Packaging structures provide physical protection for electronic components, shielding them from external environmental factors. However, components in through-hole packages are connected to the circuit board via pins, which are prone to bending or breaking under external force. This is especially true when the device is subjected to vibration or impact, as the connection between the pins and the circuit board can easily become loose, affecting circuit reliability. Existing technology involves designing pins with special shapes, such as wavy shapes. These pins can cushion external forces through their own deformation, reducing stress concentration between the pins and the package or circuit board, thereby improving mechanical strength. However, components in through-hole packages are inserted into the circuit board and soldered in place. With a large number of pins, disassembly requires heating and melting the solder joints of each pin. Due to the large number of solder joints, processing them one by one is time-consuming and labor-intensive. Furthermore, prolonged heating can cause the solder pads on the circuit board to detach or the copper foil to lift, damaging the circuit board. Utility Model Content
