Generally, the pins of thin film keyboards printed with silver paste are produced using the process of printing silver paste and carbon paste. If customers require friction resistance at the pins or continuous insertion and removal of pins without affecting the product's service life and frequency of use, our technical team combines FFC and FPC processes to effectively find common ground and meet customer needs (as there are many technologies involved, which are protected by our company's technology and will not be explained in detail).

In the process of using labels, most companies can produce ordinary labels, but for extremely small labels, the accuracy of the labels and the precision of the equipment used by customers, as well as the control process, will be considered, which will greatly increase the difficulty. The label size used by the customer for this issue is 3x4mm, with 12 small pieces connected together. The customer requires the QR code to be printed symmetrically in the center of the product. In the process of communicating with the customer, our company continued to solve the problem at the customer's site, and finally solved the problem for the customer. Each printed QR code is symmetrically centered on the product, ensuring that the customer completes the printing on time and with quality (because there are many technologies inside, which belong to the company's technical protection and are not detailed in it).
