Through-Hole Requires Selective Soldering Even though it’s a hammer, it is really only good for a specific task.
A bushing hammer, by contrast, is only really useful for texturing stone or concrete. It’s a very versatile tool and that’s why most people have one. It also has the claw for prying up nails and so on. Like any other tool, there are general purpose tools and there are tools for very specific jobs.įor instance, a claw hammer is a versatile tool that can drive in nails, tacks and do any other job that’s required of many hammers. Selective soldering is merely a soldering method a tool for accomplishing a task. Selective Soldering Is Still Very Much Needed This is precisely why so many component manufacturers rely on reflow instead of selective soldering.Įxcept for those that do. Additionally, many PCB designs don’t require complex soldering to assemble. Selective soldering machines take longer to assemble components. The board leaves the oven and can either be used in whatever product it is a component of or can be shipped to whomever will use it prior to use by the end consumer. As the board travels through the oven via conveyor, the solder begins to flow plastically and creates the solder joint. Components are placed on board, and a solder ball (usually a mix of solder and flux) is placed at the site of the joint.
A reflow oven is able to churn out many more units over a given period of time.Īdditionally, assembly is simplified. While selective soldering was formerly much more widespread – and hand soldering before that – reflow ovens have become the dominant method of PCB assembly in the industry for those same reasons. Given the production capacity and simplicity of reflow oven soldering, fewer companies are resorting to selective soldering for component assembly. Why bother with selective soldering if that’s the case? Reflow vs Selective Soldering: What’s the Difference? Also, with judicious solder ball placement, reflow soldering is actually capable of very decent precision. A reflow oven can produce a lot more units in a shorter period of time. Could reflow replace selective soldering? After all, the latter method is cheaper overall.
