Which side of PCB is correct for soldering?

The bottom side of the PCB is usually the side without components and the side that touches the solder wave during assembly. That is why sometimes it is also called SOLDER side. However more often, PCB are populated on both sides and the assembly process does not require wave soldering.

What is solder pad in PCB?

A solder pad is the part of a printed circuit board — or PCB — that supports the pins of components like transistors and chips. Typically, when devices break or components are removed from PCBs, it can result in damaged and missing solder pads.

How can you tell a cold solder joint?

Cold solder joints can be detected by visual checking or using a magnifying glass. Primarily, a cold solder joint could look dull, whitish, and convex, or deformed, which is very different from a proper solder joint. Another way to detect a cold solder joint is by using a Multimeter.

What are solder bridges?

A solder bridge forms when two points on a circuit board that are not designed to be electrically connected are inadvertently connected by solder over the top of the PCB solder mask.

What are solder pads used for?

So, what is a solder pad? It is a designated surface you get to see on a board of an integrated circuit die. They are the small surface of copper in PCBs that allows soldering the specific component to the board.

Why does my solder bubble?

It is caused by flux boiling through the solder you’re laying down. The other possibility is that your soldering iron is hotter than necessary and causing more boiling. If you are sure you’re not using too much flux, try putting a temperature control on your iron.

What is a bridge on a PCB?

And as its name suggests, it takes place when two or more pads become connected through an excessive application of solder, creating a bridge. This solder resist coating gets added to your PCB during the manufacturing process and is used to protect specific areas of your PCB that should not have solder applied.
