What flux is used for circuit boards?
For electronic devices, 3 major types of soldering fluxes are widely used: rosin-core flux (RF), mildly activated rosin (RMA), and water-soluble flux (WSF). In terms of electrical soldering, you should check the compatibility of the flux product with the metals used in your devices.
How do you use flux on a circuit board?
Use a small paintbrush or your fingers to scoop up a small amount of soldering flux. Spread the flux over the area you will be soldering, making sure to cover the wires fully. Wipe any excess flux off your fingers or brush before soldering. Soldering flux is only corrosive once it is heated up and in its liquid form.

How are circuit boards soldered in a reflow oven?
Reflow ovens solder by using multiple stages and processes along their production line. Throughout the process, the circuit board will travel on the conveyor’s belt. One-sided mesh conveyor belts are sometimes put to use in some reflow ovens. However, for larger processes, a double-sided, edge conveyor belt ensures better accuracy and efficiency.
When does the Oven reach the reflow stage?
The more efficient an oven’s soak phase, the less time will be necessary. It is, however, vital to ensure that the soak temperature is not too high. Otherwise, this can result in flux exhaustion. After the thermal soak, the process reaches the reflow stage. At this point, the oven’s temperature rises above the solder paste’s melting point.
Which is the first step in reflow soldering?
After the printing of a circuit board, the first step in reflow soldering is the application of the solder to the board. The paste must be applied only to the relevant areas of the circuit board. In this stage, accuracy is key.
When do you do a thermal soak in the reflow process?
The thermal soak brings all parts up to the same heat before entering the reflow process. The time required for a thermal soak will vary according to the board and its components.
