If you are feeling trouble with soldering? the soldering wire dripping? or the components get burned? well don’t worry in this article we will learn about how soldering works. Become a master in soldering works. Today we will go through the clear topic of Through hole soldering or TH soldering. for beginners, you need to know about the basic needs for soldering first.
Required equipment for soldering
Soldering iron
The first step of soldering is to select or buy a suitable soldering iron with a suitable soldering tip. You needs the right sized tip for the job, if it is not suitable it may cause the over spreading of the lead on the Printed circuit board.
The soldering tips are available in the thin, medium-sized tip, and big sized tip. The thin size soldering tip is suitable for the fine soldering. With this type of soldering tip you can easily get the desired soldering spot.
The too big sized soldering tip is will heat the soldering track and it may damages the soldering track or copper coating and electronics components.
Then the third one is the medium sized soldering tips, It is effectively suitable for the perfect soldering of the electronics components. It does not go over through the surface of the copper. it is the right dimension of soldering tip.
Soldering lead
The soldering wire or soldering lead is made out of several alloy metals that create the soldering joints better and stronger. The soldering wire is in two categories that are Lead and Lead-free wires.
The lead free soldering wires is most popular because less pollution to atmosphere. this kind of lead free wires are more expensive than the lead. lead is more dangerous than the lead free wires. the price of this kind of lead will most available in the local electronic markets.
Soldering iron station
The soldering iron station is the device that controls the heating temperature of the soldering iron. If you have this temperature control, should be set at between the range of 370 and 380 degree Celsius for lead wires. The lead-free soldering wires needs a little higher than the lead wires.
The best and suitable soldering wire diameter for TH soldering is 0.7 – 0.8 millimeters. Be aware of buying wire with flux, this will effectively solder the through holes. you won’t have to buy additional flux for soldering.
And the important thinks is burning flux leaves dark marks on the soldering spots and it will deposited on the tip of the soldering iron. So you needs to clean the tip for removing the dark spot before going to start to soldering.
Through hole soldering techniques explained
The successful soldering is says that the soldering is to heat up everything simultaneously. The soldering wires, soldering surface and components.
- First, you need to touch both soldering spots and the components. Then we gently adding the soldering wire which will start to melt over the soldering surface.
- After wire got melt you need to remove the wire first. followed immediately takes the soldering tip of the iron. This whole process takes a few seconds.
- If you pressuring the soldering tips will damage the board. Please note the optimum voltage is necessary for the perfect heating up of the soldering iron.
- If you are doing pressured soldering while the voltage is low, it’s wrong because the soldering tip will damages the copper tracks in the printed circuit board.
- To know the correct amount of solder is melt? the soldering spot should have a cone-shaped this is the representation of the good soldering practice. so I wind up the guide for perfect through-hole soldering.
