[0002] A computer module is also called a core board. It is a minimized computer system consisting of a processor or a microcontroller, memory, storage, power management and a circuit board. Except for the circuit board, the remaining components are mostly chips. The more common chip packaging is PGA packaging, BGA packaging and QFP packaging. The purpose of packaging is to connect the internal circuit of the chip with the outside world through pins. The pins act as a bridge. The PGA package mainly concentrates the pins at the bottom of the chip. The BGA package is more like a contact and integrates the pins on the motherboard. The QFP package is more traditional and integrates the pins on both sides of the chip. QFP packaging is also a commonly used package for micro-chips and has a more mature process.

[0003] The pins on the side of the chip are exposed to the outside, which is easy to be damaged and also easy to short-circuit, causing damage to the chip.

[0004] To this end, we propose a core board that can protect pins. Utility Model Content
