There are several ways of soldering electrical joints. Automated methods use wave soldering in which a circuit board is passed over a bath of solder. Re-flow soldering uses solder paste that is applied to the circuit board and then heated in an oven until it melts and flows across the joint. Manual soldering is largely still carried out with hand held soldering irons. The standard technique is to apply the tip of the iron to the joint and then feed solder onto the joint as the iron heats it. This method allows the solder flux to flow around the joint before it is affected by the heat. Applying the solder to the iron before touching the joint will often result in a dry joint because the flux will burn away and evaporate before it reaches the joint. Most electronic components have limits for the amount of time the soldering iron can be in contact with each pin. Generally it is in the order of 5 or 6 seconds. With the introduction of lead free solder, temperatures need to be higher to get a good joint and therefore the contact time with each component is reduced. With a shorter contact time, it is even more important to heat the joint and apply solder in an efficient manner. Production and commercial soldering skills take years to develop with apprenticeships lasting up to three years. To describe soldering techniques in just two or three paragraphs is to merely scratch the surface. Although there are many written instructions for soldering joints, there is no substitute for practice and learning from skilled wiremen.
Step 1) Twist the two parts together (only do this if you are soldering two wires together).Step 2) When the soldering iron is hot enough, tin the tip of it with solder or tinning compund.Step 3) Heat the parts that are going to be joined. DO NOT MOVE THE SOLDERING IRON.Step 4) Slowly push the solder into the heated area. Sing 1 2 3 4 5 once I caught a fish alive while you are doing this. This is becuase when you finish singing it, enough solder will have melted onto the joint.Step 5) Clean the tip of the soldering iron by rubbing on a damp sponge.Step 6)Leave the solder to cool and harden.u have to use the right type of metals but for like wires u would twist the two together like _ _ not like /\ under a wire nut and use a soldering stick to heat up the exposed part of the wire and brush the solder across and it will melt on it and down into it== ==Use the soldering iron to heat both the solder pad and the parts lead at the same time. Give it a couple seconds to heat up and then apply your solder, using just enough to cover the soldering pad and connect to the wire lead. Then let the connection cool. Be sure that the part lead doesn't move during the cooling phase or you'll get what they call a cold solder joint. It takes a little practice but it's no rocket science, either.The solder should be a `rosin core` solder. What that means is that the solder has soldering flux built into it which helps clean the connection after being heat activated and also helps to ensure that the solder will flow evenly as well as adhere to the metal.A cold solder joint looks grainy and dull in appearance. A good solder joint looks shiny. If you get a cold joint, reheat it and let the solder cool down again, and if necessary, it's OK to add a touch more solder.
It is important to remove the filter funnel before adjusting the level of the burette so as to prevent the residual drops of the reagent from dripping into the burette. Which can lead to inaccurate volume readings.
Please be more specific. Installation of Hardware or Software? These are 2 totally opposite and very important questions that must be answered before I can even begin to help you. One most important precaustion is that . Partition your drive if you want to prevent your system from cih and other viruses. after partition it will be a 100 % clean installation.
dissolving is important for nature and janitores teachers and side walk cleaners to clean the chalk up
in a bath of costic soda
to get the maximum heat at the tip surface
The soldering stand has a wet sponge on it so you can wipe off and clean the soldering iron!
yes you can, so long as you clean the metal before hand like in usual soldering
To get rid of the oxide coatings.
A: The pad is not clean it has tarnish or wrong solder with not enough soldering flux. Finally not enough heat.
Make sure the soldering copper (tip) is clean and free of oxidation add some type of non acid flux and do not over heat
Defluxer spray, compressed air, or water.
Clean and tinned with melted solder
It is important to thoroughly clean the area or the thread locker/sealant may not seal properly.
