What is the footprint in PCB?
In PCB design, a footprint is a pattern for an electronic component that will eventually be soldered there. Whether it is a through-hole connector, a surface mount capacitor, or a large ball grid array (BGA), every part that gets soldered onto or into a printed circuit board needs a footprint.
What is footprint width?
The amount of floor or desk space required by a device. For example, a small-footprint computer is a computer whose dimensions (width and depth) are relatively small. Footprint can also refer to the amount of disk space required by an application.
What does the footprint on a PCB mean?
Understanding The Footprint Of A PCB When a “ printed circuit board ” is designed and sent out for manufacturing, the manufacturer requires that a “footprint”, essentially a map, be created for the board. This shows where the parts are to go on the PCB.
How do you make a SMD footprint on a PCB?
Click on the ‘Package’ button located in the top Eagle menu, scroll down to the SSOP16 package and double click it. You should now see the white box we created. Click on SMD and create a pad that is 0.4×1.5. Drop 16 pads (this is a 16-pin device) around the outline of the package.
How to get the exact shape of a PCB?
To get the exact shape, let’s look at the dimensions of the IC again. 0.154” wide and 0.193” long. Every manufacturer will have different tolerances. Use the nominal (NOM) dimension when it is provided. If you only have MIN and MAX dimensions, I will use the usually take the midpoint between them.
How to draw PCB footprints in SparkFun?
To do this you can either drop down the layers menu and select layer 51 tDocu or… click the center button/scroll wheel on your mouse. I much prefer using the scroll wheel to select the layer because I jump to different layers a lot. You’ll see a ton of different layers. Find layer 51 and click it. Draw a box. Hit escape to stop drawing.
