flux it Slovakia

...100% of assembled PCBs are under optical control. This control is carried out by FDL520 machine by MARANTZ company or by microscope and zooming tool. Many customers demand soldering and control according to IPC-A-610, therefore final optical control is done by 3D microscope. It is possible to clean assembled boards in automatic large-capacity Super-SWASH machine or in ultrasonic machine. Cleaning will eliminate flux residuals left on board after soldering. These residuals could affect the durability of the board. If the board is supposed to be lackered, cleaning is necessary.

... copper-phosphorous brazing alloy, with good flow properties. It can be used to join copper to copper or copper based base materials (e.g. bronzes / brasses), on vibration free joints. CuP7 is very fluid at brazing temperature and will penetrate into narrow gaps and tight joints. The phosphorus contained in the alloy acts as a fluxing agent, so that it is not necessary to use an additional flux when brazing copper to copper; however when joining copper based materials (e.g. bronzes / brasses) a proper flux should be used.
