Why is Solder Flux Used in Soldering?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...
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 ...
Place on the back of the mirror and add copper tape all the way around. Use a burnishing tool to seal down the edges of the tape. Now use the paper thumb again to press down the areas of the design that are not filled. Coat with flux and set the mirror within the clamps. Put on...
The design of fluxes for a selective soldering application poses unique problems due to the localization of the soldering process. Both the heat treatment and the scrubbing action of the flux residue by the solder wave are confined in the soldered area. To address this specific issue, the flux...
The type of flux to be used in soldering depends on various factors such asType of PCBto be assembled, type of electronic components used, type of soldering machine and equipments used and the working environment. 2. Solder (Wire, Bar, Paste, Balls, Preforms) ...
When working with small components, it's often better to use a very thin piece of solder -- the larger then number, the smaller the gauge. For large components, thicker wire is recommended. Last, solder comes in other forms besides wire. When getting into surface-mount soldering, you'll ...
Modify amounts used in this recipe to suit your needs. Remember to always use the basic formula of 2 parts borax, 2 parts potash and 1 part table salt. A Two-Ingredient Silver Soldering Flux Recipe Step 1 Make a silver soldering flux using just borax and salt if you lack potash. This...
PURPOSE: To provide a flux with which the need for an ionic residue-removing washing step is eliminated by incorporating rosin and a dibasic acid which are mixed in a mutually supplementing ratio in the flux. CONSTITUTION: The low residue soldering flux is formed as a rosin-containing or ...
Use Little Soldering Flux Soldering Flux Soldering flux is usually applied to the solder joints before soldering. The flux reduces the melting point of the lead so that the solder lead will melt easily and spread uniformly on the solder joint. Liquid type flux is better since it will not leav...
Soft soldering is a technique used to join wires, fix electronic components onto circuit boards and bond copper pipes together. This tutorial shows you how to solder step by step.
