SMD Soldering Workshop
■We want to share with vou some soldering techniques that will allow you to solder 0.5mm pitch devices and small 0603 components. This is by no means a certification course! There is a lot of information, training, and practice that goes into proper soldering. We just want to show you the basics.
■Soldering is the act of heating up a pad on a PCB (printed circuit board) and a pad or wire on a component. Adding solder to these two heated pads causes the solder to melt. The solder will flow towards the heated pad and component. Removing the iron, the solder will quickly solidify creating an electrical contact and a very strong mechanical joint.
■Jumpers are bad. A jumper is an electrical connection that should not be there. As ICs and components get smaller and smaller, their pads are being located closer and closer to one another. This tight packing of pads increases the chance of accidentally solder two neighboring pads to each other- in other words a 'jumper' is created. We will show you how to minimize and remove bad jumpers.
