Printing
Printing is one of the key steps in RF antenna substrate manufacturing. During the printing process, a copper foil layer is covered on the surface of the substrate to form a circuit connection network. Manufacturers use special printing equipment and techniques to ensure that the thickness, uniformity and accuracy of the copper foil meet design requirements.
Etching
Etching is the process of removing unwanted portions of copper foil from a substrate. The manufacturer puts the printed substrate into an etching solution, and the excess copper foil is etched away through a chemical reaction, leaving the desired circuit pattern. This step requires strict control of the concentration, temperature and time of the etching solution to ensure etching quality and accuracy.
Placement
During the placement stage, electronic components are placed precisely at predetermined locations on the substrate. These components may include antennas, filters, amplifiers, usw. Manufacturers use automated equipment or manual operations for placement to ensure accurate component placement and good pad quality.
Welding
The last critical step is soldering, where the electronic components are soldered to the substrate. Soldering is usually done using surface mount technology (SMT) or through hole soldering technology (PTH). Manufacturers will use high-temperature furnaces or infrared heating equipment to melt the solder and connect it to the pads to ensure the firmness and stability of the soldering.
