What is Diamond FLux FN231 Organic Components Organic components are substances created by nature. To create fluxes, these components go through stages of purification and transformation for ease of use and improved quality. Main Component - Rosin The main component of this flux is Rosin. It, too, has gone through a process of purification and transformation to be easily applied as a paste. Thanks to rosin, the flux has a yellow color. Easy for application Diamond Flux FN231 has a non-removable plunger in its design, which will add to your convenience in use, as the plunger is a reliable integral part of the design. Vacuum packaging Needed for longer flux storage, as some components may naturally evaporate. Vacuum packaging also serves for safer transportation, preventing various situations. Soldering, Wettability and Cleaning Preparation for Soldering Connector There is a printed circuit board on which the connector is soldered. Diamond Flux FN231 for soldering and the connector itself. SnPb solder wire was used for soldering. After Soldering Process Before soldering the connector, a Diamond Flux was applied to the place of soldering. The picture shows the result of soldering. Smooth and shiny solder joints. After Cleaning Process Diamond Flux FN231 can be cleaned with industrial and manual water-based and alcohol-based PCB cleaners. Picture after cleaning with an alcohol-based spray cleaner. Useful Soldering Tips. Soldering Temperatures. Different alloys require specific soldering iron tip temperatures. For PbSn alloys use 300 (572°F) -320℃ (608°F), and for Pb-Free alloys use 330 (626°F) - 350℃ (662°F). Avoid setting temperatures too high, as it can lead to burnt and blackened tips, making soldering difficult. Soldering Iron Tip Maintenance. Periodically clean the soldering iron tip using Brass Sponge Tip Cleaner or Tip Cleaner Spouge. For proper tinning, use Tip Tinner. A clean and tinned tip ensures smooth soldering. Soldering Time. Limit the contact time between the soldering iron tip, surface, and component to 3 seconds. This timeframe is sufficient for tinning and solder flow. Soldering Quality. Reliable connections depend on the PCB quality, solder alloy quality, and flux quality. Oxidation on the PCB surface hinders soldering. Poor-quality soldering wire or soldering paste contain impurities of foreign metals or the wrong ratio of metals. The lack of soldering flux affects wetting and cleaning of oxides from surfaces. Soldering Flux Class. Pay attention to the flux class in the soldering wire. Some fluxes can be conductive and highly active. Aim to use the same flux class in the wire, solder paste, and separate flux (jar, syringe, bottle). The same flux class is of great importance for future trouble-free operation of the device. Choosing the same flux will make the task easier and improve the quality of your device. Some fluxes will need to be washed off completely, and some will not - is No Clean Class, like ROL0. No current leakage Soldering Flux Over a wide voltage range Diamond Flux FN231 shows excellent results in protecting the printed circuit board from current leakage after repair and soldering. Unwashed flux residues will not cause problems with current leakage. Voltage Range 0.1 - 2000 After applying - 10 Mega Ohm After soldering - 18 Mega Ohm 1 Day - 25 Mega Ohm 7 Day - 110 Mega Ohm 30 Day - 670 Mega Ohm 45 Day - 2.5 Giga Ohm > 45 Day > 2.5 Giga Ohm About Product Diamond Flux FN231 from Developers Team. Diamond Flux FN231 soldering flux was obtained as a result of deep development and in the spring of 2023 the commercial product was ready to start sales. Development was carried out in Florida, Hallandale. It is also produced and packaged here. The research lasted about 1 year and 17 serious experiments and an insane number of small tests were done. To create a solder flux for soldering electronics, a number of requirements must be taken into account, and each requirement is very important. Some of the requirements: No halogens, no current leakage, corrosion resistance, operating temperature range, boiling points, no smoke during soldering, toxicity indicators, harm to the environment and people, shelf life, easy cleaning and many other indicators that are no less important. To achieve stable performance, it is necessary to carefully select chemical components, calculate formulas and molar masses. Each iteration of the soldering flux formula must undergo a series of checks and tests. The tests also require equipment that was purchased. Only numbers obtained as a result of experiments will give a complete understanding of the operation of the resulting formula. And now the developer company Express-24 LLC is confident that if soldering flux residues remain under the replaced microcircuit or SMD components, then the Printed Circuit Board will work, there will be no current leaks, and there will be no corrosion. Flux consists of organic substances that have been processed and purified to one degree or another. In its composition, each chemical component plays its own important role. This soldering flux is low activity, which is why it works well in areas where there is no corrosion on the conductors. This is an excellent flux for soldering new Printed Circuit Boards in manufactory and for repairing various electronics PCBs, including wire harnesses. There is no way to wash the flux out from under the wire braid, which means the solder flux under the wire insulation will remain forever and it should not cause harm to the wire - this is the most important indicator. We also thought about the packaging and understand that when transporting soldering flux in syringe, its packaging may be damaged, and for this purpose the syringe was packed in a vacuum package, which also contains a needle for the syringe. We will be happy to answer your questions if any difficulties arise during the soldering process. Feel free to contact Amazon internal mail for any technological difficulties! We have extensive experience in the electronics PCBs production and repair of electronics, in technical processes on any equipment for the manufactory and repair of Printed Circuit Boards. Thank you!
