Every soldering process, such as selective soldering, wave soldering or reflow, has benefits and drawbacks. In certain instances, selective soldering is clearly the appropriate soldering method and wave soldering is clearly the better soldering process in others. In order to choose which to employ, one has to consider the intended application for which the wave or selective soldering machine will be used.
There are a number of selective soldering defects, which negatively impact the products made in the selective soldering process. A board made with a soldering defect will either not function correctly upon leaving the factory, or will be prone to malfunction in a much shorter time span than is acceptable.
That opens the door to failures, which not only pose a problem for the end user but also to the producer. Reputations can be ruined by a bad batch or two, or even a defective unit or two. To guard against any PCB or component failures, soldering system defects need to avoided at all costs.
Hand soldering is the simplest form of soldering there is, since it's about the furthest thing from complicated that there is. It's also the easiest form of soldering. Given the simplicity of hand soldering, there isn't too much that can be made a mess of.
Selective soldering, on the other hand, is much more complicated as there are so many parts to the process that are involved. We developed a brief guide to selective soldering if you are intersted in learning more.
We know that Selective soldering is different from other soldering methods, but what sort of selective soldering technologies are out there? What sort of benefits do they offer over other types of selective soldering technologies or different soldering methods?
