The main function or use of flux in any Printed Circuit Board Assembly or rework is to clean and remove any oxide and impurities from the board. These oxides deposited on the board may not permit good solder joints. If the solder joint is poor, there will be poor electrical conduction or...
1) Different welding methods require different states of flux. Liquid flux should be used for wave soldering and paste flux should be used for reflow soldering. 2) When the welding object has good solderability, it is not necessary to use a highly active flux; but when the welding object ha...
The selective soldering application requires a combination of performance attributes that traditional liquid fluxes designed for wave soldering applications cannot fulfill. First, the flux deposition on the board needs to be carefully controlled. Proper fine tuning of the flux physicochemical characteristics ...

Liquid Flux is Essential The only way to ensure that flux reaches the surface oxides before solder melts is by applying liquid flux first. And more than just a trace amount of flux is required. Flux acid (the part that removes oxides) is neutralized during the deoxidation chemical reaction. ...
Adding a liquid flux before reflow may not help a lot as the flux elements in paste are designed to survive the reflow ramp and soak, liquid fluxes are designed to activate more quickly and may not prevent or remove oxidation after the reflow profile exceeds 100C or so. All of the active...

Liquid flux tends to crystallize and or seep under pads, under the SMT parts, etc. and does not stick around long enough to get all of the solder wicked off. In this particular scenario, never, ever attempt to mechanically scrape or use a Dremel (not Drummal) tool, because in this ...
Liquid-based cytology is a cervical cancer screening technology that inspects cells by dissolving them in liquid and is used as a main screening tool for invasive cervical cancer. The purpose of this article is to demonstrate how fluid-based cytology has surpassed conventional cytology in the ...
Flux - Flux is available in liquid or gel form (I find the gel to be more forgiving to work with), and is used to assist the solder flow between the copper taped pieces. Brush every copper foiled surface with flux before soldering every time for best results.Grinder - if you're just...
