Fixing Solder Mistakes Or ResolderingEven if you have been soldering for years, mistakes are still bound to happen every once in awhile.
Whether its a misplaced component or the solder just doesn’t take, soldering mistakes are usually pretty easy to fix.Soldering is pretty forgiving which makes it pretty easy to fix most any mistake you might make. If you apply a little too much solder or position a component incorrectly, you can reheat the joint, melt the solder and then reposition it correctly.
Solder can be heated and cooled.Mar 27,2014 773 views. How to Solder Like a ProNow that you know the basics of soldering, it’s time to learn how to solder like a pro. Here are some helpful tips to creating professional grade projects:1.If your soldering iron isn’t working properly, try cleaning the tip. The residue from solder and dirt that accumulates on the tip over time make it difficult for the soldering iron to heat properly and reduces the heat applied to the solder.2.Choose a soldering iron with a range of at least 40 to 60 watts.

The S4 Flight BoardThe flight board, which is considered the backbone of the entire S4 payload, is a Printed Circuit Board (PCB). The flight board provides the foundation that keeps all the components firmly in place. It also provides a route for the power and information to travel between the components.
This is achieved through a system of wires, called ‘traces’, that are printed directly on the board.

How to Surface Mount Components Onto a Printed Circuit Board (PCB)Soldering surface mount components isn’t difficult, but it will require a good eye, a steady hand and a soldering iron with a small and clean tip. In a proper joint, you want the solder to adhere to both the PCB pad and the component lead rather than having the solder ball up on the end of the component and not adhere to the PCB pad.First, apply a small bead of solder to one of the PCB pads for the component being installed.

Printed Circuit Board HistoryStarting in the 1940sPrinted circuits were first used in the 1940s to connect discrete components together. By the 1960s, PCBs were widely used in all electronic systems, but still mostly connecting discrete components. Integrated circuits (chip) were emerging and added to the boards, and by the 1980s, PCBs were holding large quantities of chips.
Today, printed circuit boards typically connect mostly chips with only a few discrete components, each chip containing from a few thousand up to hundre.Mar 26,2014 475 views.
