Selective soldering is an automated system that pumps molten solder up from a reservoir through a nozzle to coat the leads extending out the bottom of a circuit board. If a board cannot be wave soldered, then it must either soldered by hand or run through the selective soldering process. Wave soldering does have some limitations, however, and not all boards can be run through this process. Wave soldering is the preferred method for production soldering because it can be quickly set up, and it will solder a lot of boards in very little time. The circuit board rides a conveyor belt through a molten wave of solder that wicks up through the holes and around the pins to create the solder joints. Although initially created for boards with all thru-hole parts, it will solder some surface-mount technology (SMT) parts as well. Wave soldering is the standard process that has been in use for many years to solder parts onto a circuit board. wave soldering can help out the assembly of your printed circuit board. Let’s take a look here at why selective soldering vs.
The selective soldering system gives PCB assemblers the right tool they need to resolve some of the problems that wave soldering isn’t able to. Or, they could use a tool that is specifically designed for the problem at hand. The assembly technicians could spend a lot of time trying to make these traditional processes work. There are many times during PCB assembly when the more traditional tools or methods-such as wave soldering-are not always the best choice for one reason or the other. The best way to deal with problems like these, whether it is a simple home repair or building a circuit board, is to use the correct tool for the job. You know what happened next: pliers, saws, frustration, some regrettable language, and way too much time used up by this one annoying problem.
#Wave soldering vs reflow driver#
Since I didn’t have a Robertson driver at hand, I tried to remove it with a regular Phillips driver instead and ended up stripping the screw head.
#Wave soldering vs reflow full#
(And, in the interest of full disclosure, I didn’t know it either-I had to look it up.) Anyway, I ran into one of these screws the other day while doing some simple home repairs. Have you ever had a project around the house where you needed to remove an old screw and discovered that it had a square head on it instead of a standard slotted or Phillips head? Those square-headed screws are called “Robertson,” in case you didn’t know.
