Learning how to solder RF components is an integral part of many electronic designs, primarily due to their small size and frequent use in sophisticated circuit boards. Needless to say, ensuring that the solder joints made are reliable and of high quality is critical and a skill with tangible results.
The most important tool for a solderer is the soldering station, which is designed specially for soldering and is therefore of much importance when soldering smaller components such as those found in RF design. A range of basic instruments is necessary, such as soldering paste, a variety of different tips, flux and solder. With this all in hand, a solderer will be ready for the job ahead.
The exact circuit and components that the solderer will be using will determine the specific technique that must be employed, as every device triggers a unique approach. The soldering paste is applied directly to the pads on the PCB, in order to create a conductive joint between the board and the device. Too much paste will weaken the binding, while too little will prevent good contact. Once the paste is applied, the components will be placed on the board and held in place with a vice before the soldering is begun.
The next step, after preheating the tin and the pad, involves soldering the component itself. The standard process here is to start at the center of the component, using the lead as a point of reference, and working outwards in a circular motion. It is important to remember to keep the tip at right angles to the board, not allowing it to slant or to contact any other exposed metal on the board.
When soldering high frequency, even a seemingly perfect joint can prove insufficient or unpredictable when it comes to emissions and impedance control. To achieve an ideal RF soldering job, one must take the extra step of measuring Smith Chart impedance before and after soldering, to ensure that the joint is behaving as predicted.
Finally, care must be taken to clean the board and components after soldering, using a soldering and desoldering iron. This eliminates any heat-related impurities which can reduce the reliability of the joint. With this complete the Linux RF soldering technique will be finished, and your task complete.
