Liquid Soldering Flux


for Soldering Electronics PCB


Liquid Diamond Flux FN232

Liquid soldering Flux FN232 Description

The liquid soldering flux Diamond Flux FN232 Liquid State Soldering FLux in 10g bottle with Brush. Bottle contain bushing for liquid leakage protection. Manufactured in the Florida, USA, from organic components and Rosin. The Diamond flux FN232 belongs to the class RMA ROL0 no-clean, does not contain halogens. Residue after soldering does not cause corrosion on the printed circuit board(PCB), components and wires. Flux residue does not cause electrical leakage. Provides excellent wettability of soldered surfaces for better solder adhesion. The flux is perfect for soldering any BGA, QFN, SMD, DIP, SOT and other electronic components. For comfortable application of flux, a brush is built into the lid. The bottle is also equipped with a sleeve that protects against leakage if accidentally tipped over. FN232 perfect washed off with any PCB cleaner. Responsible soldering requires high-quality Fluxes!

About Diamond Flux FN232 from Developers

  Diamond Flux FN232 liquid soldering flux with brush in cap was obtained as a result of deep development and in the summer 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 6 month after first companies product Diamond Flux FN231. 7 serious experiments and an insane number of small tests were done.
  To create a liquid solder flux for soldering electronics, a number of requirements must be taken into account, and each requirement is very important.
  The requirements: No current leakage, no halogens, corrosion resistance, operating temperature range, 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 liquid 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 liquid 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.
  This liquid 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 liquid soldering flux in bottle, its packaging may be damaged, and for this purpose the bottle with brush was packed in a vacuum package.
  We will be happy to answer your questions if any difficulties arise during the soldering process. Feel free to contact with us for any technological difficulties! We have extensive experience in the electronics PCBs manufactory and repair of electronics, in technical processes on any equipment for the manufactory and repair of Printed Circuit Boards.

Thank you!
