System and method for detecting locking of circuit board element

Abstract

The invention discloses a system and a method for locking and detecting elements of a circuit wafer, and the invention is used in electronic devices for detecting situation of a circuit wafer element that is locked on a circuit wafer by a screw and deciding whether to start or not start a power source unit. The system for locking and detecting elements of the circuit wafer comprises at least a decision unit which is provided with multiple input and output ends; an electricity-conducting circuit which is arranged on the circuit wafer and consists of at least one group of a first pattern metal and a second pattern metal, and at least one resistance element, furthermore, the first pattern metal covers outside the second pattern metal along an unclosed curve, and the circuit wafer element is locked on the circuit wafer by a screw. Under situations that an exposed end of the screw presses or does not press on the first pattern metal and the second pattern metal, the system generates high electric potential or low electric potential which are connected with an input end of the decision unit, thus leading the decision unit to control whether to start or not start the power source unit.

Description

technical field [0001] The present invention relates to a circuit board component locking detection system and method, more specifically, it relates to detecting whether the screw is tightly locking the heat sink on the CPU, so that the heat source of the CPU can be effectively conducted to the heat sink. piece. Background technique [0002] Taking a server as an example, it can be roughly divided into three parts, namely the host, display, and input devices (such as keyboards, mice), etc. Among them, the host contains many components for different purposes, and each component They are also composed of many electronic parts, IC parts and chips for different purposes. Because these IC parts and chips will generate heat energy during operation, as the operation speed becomes faster and faster, the heat emitted by a computer during operation becomes a heat source that cannot be ignored. [0003] The main components that generate heat in the host include the CPU, hard disk, ch...

Problems solved by technology

[0007] In view of the above-mentioned shortcomings of the prior art, the main purpose of the present invention is to provide a circuit board component locking detection system and method, which can be used to detect whether the screw is tightly locking the heat sink on the CPU, and can solve the problem caused by locking. The firmware is loose or not locked, and there is no way to lock the circuit board components on the circuit board, which will lead to the problem of product failure, thereby improving the stability of the product
