For example, during transportation, some plug-in products may have crooked pins due to vehicle bumps or improper handling, which may cause the pins of the products to be deformed or difficult to insert when customers insert the boards. After discussions and rectifications by our company's quality department and communication and confirmation with customers, we have added bases or bottom plates for different products. The bases and bottom plates are hard and fix the pins of the products, so that the pins of the products will not be deformed due to external forces during transportation. We have also added secondary pin calibration operations for some products, so that the pins can enter the holes more accurately, and customers can easily insert the boards during the plug-in process, which greatly improves the customer's efficiency. Our company will continuously update products and solve problems according to different customers and different products, and meet the needs of each customer in response to problems that arise during product use.
