2. Water Soluble FluxWater soluble flux is also known as organic acid (OA) flux. It is is primarily composed of organic materials other than rosin or resin. Water-soluble flux provides good soldering results because they have good flux activity. They have good wetting action (ability to ...
Using rosin paste flux is a great way to avoid oxidation and make your soldering much easier and last longer. Put them on the joint and let them melt before adding solder. But remember not to use the acidic one SEE MORE: How to Use a Test Light on Positive and Ground Wires Car Has ...
Another way to differentiate the solder paste is through their flux. There are three types of fluxes used in solder pastes:Rosin - A rosin-based solder paste, as the name suggests, is made by using rosin. It is a substance obtained from pine trees. You can clean the excess flux using ...
For example, you can have a corrosion problem even from rosin flux if you use them generously for rework leaving behind lots of flux that never got hot enough to be activated to become benign. There are three simple requirements that should be given the force of an industry standard such ...
Vise (or something similar to hold a PCB) X-acto (or utility blade) Good quality solder (60/40 rosin core preferred); RoHS can be used Solder wick Liquid/paste solder flux (no acid flux or solder paste!) Magnifying glass De-fluxing spray (or rubbing alcohol) ...
Separating large copper foil surfaces: If there are large copper foil surfaces, they can be separated into small pieces with solder resist film to improve soldering performance. Fitech Flux Shenzhen Fitech Co., Ltd. produces fluxes including rosin type and epoxy resin type, which are highly active...
The identification designator for the flux in the solder paste is defined in IPC STD-004. This designator has four characters. The first two define the base material. Rosin (RO), Resin (RE), and Organic (OR) are the most common for reflow solder pastes. The other two characters define ...
If your tip is still oxidized after attempting to tin the tip, it's time to bust out tip tinner, also known as cleaning paste, reactivation paste, or chemical paste. Tip tinner is generally a mix of aggressive flux and solder, serving the dual purpose of eating away oxidation while tinnin...
(Side note: A new water-soluble flux core is starting to gain some traction as an alternative to rosin core because it is more environmental friendly.) Summary The main types of solder are lead and lead-free. You can use both for electronics, but it can be easier to work with lead-bas...
Use Hot Air Gun at 380℃ to heat the solder wick with soaked rosin to remove tin. Apply Paste Flux. Put a new USB IC in position. Solder with Hot Air Gun at 380℃. Clean with PCB Cleaner after the motherboard has cooled. 步骤7 ...
