Rosin (R) Flux: It has only rosin and is the least active. This type of flux is mostly used for surfaces that are clean. It leaves virtually no residue after soldering. Rosin Mildly Activated (RMA) Flux: It has
Rosin Flux Rosin, or “Type R” flux, is the most basic soldering flux that has actually been used for thousands of years. Rosin is naturally derived from pine tar rosin, which can be farmed from trees. When it’s used as a soldering flux, rosin is then dissolved as a solvent in iso...
Considerable progress has been made for paste dispenser, screening and stenciling for pastes on substrates. Each method of dispensing solder cream has its own pros and cons but the most widely used method is stenciling for both rework and large scale production. Vastex is a well known ...
Liquid flux poses a greater risk than paste because it’s harder to control the application flow and volume. Hand soldering The liquid is dispensed by hand or in a spray or foam format during wave or select soldering. In the wave process, the liquid can flow to the top side of an assem...

How is soldering flux used? Solder flux is available as a liquid or paste. While the changes in the liquid are held in flux pens or bottles, the majority of solid flux are kept in tiny jars or tins. Use all safety preventive equipment when soldering to improve your security. A breakdown...
when the alloy solder is selected, it is necessary to boost the activity of the solder flux to increase the wettability of the solder paste on the surface of the metals. However, the increase in the activity may produce more flux residues, which can corrode the metal surface after soldering...
Reflow soldering is a process that involves attaching surface mount components to a circuit board (PCB). Solder paste, a mixture of powdered solder and flux, attaches many small electrical elements to a contact pad. Use controlled heat to reflow the solder paste into a molten state; this creat...
Reflow soldering is to remelt the solder paste pre-distributed on the printed board pads to realize the mechanical and electrical connection between the solder ends or pins of the surface mount components and the printed board pads
SMT PCB is a method of placing electronic components and circuits on printed circuit boards (PCBs). SMT is a subcategory of Electronic Hardware Assembly. Features of SMT PCB: SMT is used for large production
