Good Soldering Techniques

Incomplete feel if I only discuss about the type of solder type commonly used by technicians, in this article I will discuss about good soldering technique. Soldering technique is very important because it will affect its outcome, could be a series not even bekeja properly. Or it could also result in damage to the components installed.

Some examples of bad solderanThe quality of solder joints depends on several factors, including soldering tools used, soldering skills, types of tin solder and fields that are used for soldering.

Solder is used should be in accordance with the components to be soldered because it will affect the smooth flow of molten tin solder, or known as wetting, namely the ability of molten tin solder to wet the soldered surfaces. Of course, the smooth flow of molten tin solder, tin solder the easier it is for the liquid to moisten the surface of the soldered objects, so that the resulting solder connections for the better. Conversely, the flow is not good solder connection will produce a thicker or if too severe even form a lump of lead solder that does not stick, of course, such a connection is bad.

Types of tin solder is used also influential, tin solder wire diameter of the right is determined by the size of the solder joints are done / dependent component. Small solder joints, such as for SMD components, requiring only a little tin solder. In order for the amount of molten tin solder can be adjusted accurately and avoid excess tin solder that can bridge the solder joints that meeting, lead solder used must have a small wire diameter, ie 0.4 mm - 0.5 mm. If the TV might be somewhat rarely used, most only to MICOM IC only, ... except for TV which is already using modules such as LCD / plasma TV.

Vice versa, if the solder joints that do are large, in order to melt the solder tin more quickly, we recommend using tin solder wire with a diameter larger, namely 0.8 mm - 1mm (flyback / Tr power)

For standard components, you can use tin solder wire with a diameter of 0.5 mm -0.8 mm, according to custom or existing inventory (resistor / capacitor / diode).
Here are some good tips on how meyolder:* Make sure the PCB copper surface polished, if opaque then amplaslah with a fine sandpaper
    * Remove rust on foot component with mengeriknya until glossy, the rust on the legs is marked with no-slick component parts leg
    * When soldering, solder paste on copper PCB (not too long) then tin in solder paste to taste, wait until the tin melt and spread
    * Immediately after the tin solder spread throughout the area, keep the tin solder and wait until winter and you are sure the foot component is united with the point on pcb (printed circuit board).

 

Good Soldering Techniques
And here are some things that need to be considered in soldering:

    * Calculate time per each component soldering, try to peyolderan semiconductor components (small Tr, IC, Diode) is done as quickly as possible to avoid overheating the component, because the components of this type are particularly vulnerable.
    * Be careful soldering because the solder heat generated can damage the components when receiving heat belebihan, back again to how much power / watt soldering you have and adjust to the type of component.
    * Use an easily melted tin, always note the diameter of the tin is used.
    * Use a solder that has a buffer to make it more secure.
Often components but does not stick to the tin solder is hot enough, it could be dirty, so his eyes solder heat that flowed into the tin to be blocked. To wash the eyes of the solder, of course no way is used to heat the solder, then rubbed gently with a clean sponge iron. If there was no sponge iron, can be fitted with wet nylon fiber. After that rubbed into wet sponge and coated with tin solder. Repeat until tin solder to coat the solder with a perfect eye.

Clean the solder eyes
For the new solder that is usually shiny, need time to be able to coat well. Likewise, solder whose eyes are dirty. But once successful, will usually be easier to maintain a good layer of tin, simply by rubbing the eye often soldered into a damp sponge when in use ....
