Description
[ technical field ] A method for producing a semiconductor device
The present invention relates to a slot detection device, and more particularly, to a memory card slot detection device for detecting a memory card slot.
[ background of the invention ]
A memory card slot is a slot for an electronic device to insert a memory device such as an SD card, a TF card, or the like. If the contact impedance of the memory card slot is too large or the open circuit is not well contacted, the memory card mechanism is deformed, the pins are bent and deformed or the plating layer is oxidized, and the memory card can not work normally. Therefore, when the contact resistance performance of the memory card slot is detected, a factory tester performs a plurality of tests on the contact material, the gold plating layer and the abrasion resistance to confirm whether the contact performance is normal. The current impedance detection mode is as follows: 1. inserting the memory card into the memory card slot, and forcibly pushing the spring to enable the memory card slot to tightly clamp the memory card; 2. cutting the shell of the memory card slot, and well leading the probe of the ohmmeter to probe in for measurement; 3. and finally, whether the contact pins of the memory card and the contacted pins of the memory card slot are normally conducted or not and whether the impedance value between the contact pins and the contacted pins is in a standard range or not is confirmed. However, the above process is time-consuming and labor-consuming, and the cutting of the casing of the memory card slot can cause the contact pins on the memory card slot to shake off, and may also bend the pins of the memory card, which eventually results in inaccurate measurement.
In view of the above, it is necessary to develop a device for detecting a memory card slot to meet the requirement of detecting the memory card slot and improve the current detection efficiency.
