Description

Technical Field

[0001] This utility model belongs to the field of equipment debugging technology, specifically relating to a FLASH debugging device based on rigid board connection. Background Technology

[0002] In embedded minimum systems, the main software program is stored in FLASH memory. During the initial software debugging phase, the boot program needs to be debugged frequently. If problems occur, the device will fail to start. In this case, the FLASH memory will most likely need to be replaced to restart the debugging process. Software debugging often requires multiple iterations, and repeated desoldering will damage the PCB, causing solder pads to fall off. Once solder pads fall off, the PCB will have to be scrapped. Even if repairs are done with jumper wires, performance will still be degraded. Even after mass production, when a new version of the software is released, it is necessary to burn the FLASH memory onto the board for verification. Each version release requires desoldering the FLASH memory, which will also damage the motherboard.

[0003] Based on the above shortcomings, FLASH debugging has been further developed. It can be debugged by using jumper wires or flexible circuit boards to lead the FLASH debugging socket, which can improve debugging efficiency and reduce losses to some extent. However, repeated FLASH desoldering will inevitably lead to the scrapping of the motherboard, further increasing R&D investment; the time required for desoldering is also a form of R&D resource investment. Leading the FLASH out via jumper wires will greatly compromise signal integrity and requires high soldering skills; leading the FLASH out via flexible circuit boards, excessively long traces may still cause the FLASH to be unrecognizable; the fixture itself is also not very robust and is easily damaged during use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a FLASH debugging device based on rigid board connection that does not require desoldering of FLASH.

[0005] This utility model is implemented as follows: a FLASH debugging device based on a rigid board connection includes: a rigid board, two connecting pin seats connected above the rigid board, a programming socket fixture plate welded above the connecting pin seats, and a programming socket welded above the programming socket fixture plate. The FLASH is placed in the programming socket. Software debugging can be completed simply by replacing the FLASH in the programming socket. The rigid board is a rigid board of the same volume as the FLASH; Furthermore, the rigid board is connected to the PCB below.

[0006] The advantages of this utility model are: 1. FLASH replacement does not require desoldering, avoiding motherboard failure; 2. FLASH debugging does not require the involvement of multiple departments; the testing department can complete it independently, improving R&D efficiency. 3. The method is simple to implement, requiring only basic welding skills and not advanced welding techniques; 4. The upper part of the programming socket can be used on multiple motherboards, resulting in a high reusability. 5. Shorter traces provide better signal integrity and avoid debugging problems caused by signal abnormalities. Attached Figure Description
