A printing process for mobile phone antennas (transfer printing) - Mobile phone antenna PDS transfer printing silver paste

PDS is a transfer printing process for printing mobile phone antennasConductive silver pasteApply to the surface of the workpiece, and then form a conductive three-dimensional circuit by printing multiple layers of silver paste. The advantage of PDS is that it can directly print circuits without the need for special laser modified materials, which can significantly reduce costs. It is difficult to handle in antenna design that circuit conductivity can be achieved in both corner and through-hole structures.

Given the high cost of investment in LDS technology and laser equipment, the commonly used mobile phone material PC cannot be used and special specialized raw materials must be used. The price of LDS antenna products is several times more expensive than ordinary antennas, and the bottleneck restricting the development of LDS lies in the high fixed investment of laser machines (3 million yuan/unit for single head and 6.5 million yuan/unit for three heads). The value advantage of PDS technology lies in breaking the myth of LDS antenna prices!

PDS is printed directly inside the phoneConductive inkThe PDS (PBINTI NG Direct Structure) technology used to make antennas is adopted by Samsung's first tier suppliers of smartphones. PDS technology is a built-in antenna manufacturing method that can enhance wireless radio frequency (RF) characteristics. It is a patented process technology that uses conductive ink to form an environmentally friendly electroless coating on specific plastic material printing areas, improving RF characteristics and reliability.

The PDS process involves printing an antenna pattern on the upper surface of a plastic shell, which needs to extend from the side of the plastic shell to the lower surface and be connected to the feed point of the mobile phone circuit board to achieve a successful connection between the antenna and the circuit board.

YB500 series launched by Advanced Institute TechnologyConductive silver pasteSpecially used on PDS process antennas, this silver paste has the characteristics of good wear resistance, low curing temperature, and good conductivity; YB500L has the characteristics of low-temperature rapid curing and no bubbles when used through holes.
