1/9/2023 0 Comments Wave soldering vs reflowWhen much heat is applied, it can lead to thermal issues for the board, its components, as well as other already-placed solder joints. It also requires the circuit board to undergo serious heating, in order to achieve a great solder joint. One disadvantage of doing hand soldering manually is the time taken required. Following these benefits, are a few pitfalls you need to take note of. Below are some of the great benefits offered by the selective soldering process. However, there are several benefits that have led selective soldering to be chosen as the preferred method in so many cases. This opposes a full wave, which hits all the joints of the solder at once. The components are sequentially soldered individually by a local wave. Process Involved in Selective SolderingĬompared to wave soldering, the process involved in selecting soldering is a slower one. However, with the process of selective soldering, you can get rid of the possible issues associated with manual soldering. Doing this manually is time consuming and could cause human error. This will mask off components of the surface mount on the bottom side, giving way for the solder wave to only contact the through hole pins.įor cases where parts of the surface mounts are too close and you cannot use a masking pallet, the other alternative for you is to solder the through hole leads manually. Their boards have dense parts placement on the board’s back. However, selective wave soldering comes with its limitations. This is because it takes less programming and preparation, and it is quick. For through hole component soldering, wave solder is your first choice. Selective solder helps to fill the gap between manual hand soldering and automated wave solder. This is based on the Gerber data used for the board fabrication. You can also develop this programming on a computer having solder system software in it. This is to make sure the best solder joints results. This program is developed by the operators for the panel or board being assembled.Īsides from the movement, the programming also allows the operator to have precise control or the time duration of the application of the solder, and the solder’s temperature. This movement works under a program’s control. The mechanism of this solder is built on an assembly moving in multiple directions. It makes use of a pump system and solder reservoir to move molten solder to pass through a nozzle, then to the leads coming through the circuit board’s bottom. A system for selective soldering is a machine, which will solder thru-hole leads on a panel or board.
