Airfreight Not Available. For hand soldering, flux can be applied by a flux pen or is usually in the core of the solder wire that most technicians use.
For the automated soldering processes used by CMs during printed circuit board manufacturing, there are a couple of different ways that the flux will be applied. Within these categories are different types and chemical compositions of the fluxes depending on the needs of the components and boards to be soldered. Depending on the automated soldering process being used by your contract manufacturer, the flux will be applied in these methods:.
The method that the flux is applied to each of these solder processes is carefully controlled to ensure that the flux is able to do its job without compromising the integrity of the soldering process. For instance, if a solder paste is being used that has a greater concentration of solvents in it then other types of paste, there can be a problem if the flux is heated too fast. For this reason, the solder reflow process is carefully controlled with preheat, temperature soaking, and reflow stages.
Another aspect of flux is the need to clean it off the circuit board after it has done its job. Some fluxes are corrosive, and their residue may continue their activity and harm the circuit board long after it has been manufactured.
The three categories of flux mentioned above each have their own cleaning needs:. For those fluxes that are more corrosive, cleaning is essential. Some processes of circuit board manufacturing, such as shielded areas of the PCB that go through wave soldering, can potentially hide flux residue. In addition to the corrosive problems of the more active fluxes, however, even the residue of no-clean fluxes can interfere with PCB testing, optical inspection equipment, and some sensitive electronic components.
In general, it is best to clean flux residue whenever possible. There are many different categories, types, and compositions of flux out there for soldering, just as there are many different types of solders and soldering processes. To be assured that your PCB design is going to be manufactured correctly with the best combination of materials and processes, you need to work with a CM that has a complete understanding of all of it.
Your CM should have years of experience working with these different materials and have the equipment and resources to facilitate these processes. At Tempo Automation , we do have the experience, skills, and facilities needed to manufacture your PCB. We have been assembling and soldering circuit boards for a long time, and we will make sure that your design is built to the highest levels of quality. And to help you get started on the best path, we furnish information for your DFM checks and enable you to easily view and download DRC files.
