How to make a SMD footprint and schematic library?
This tutorial will show you how to create a custom SMD footprint and schematic symbol library. This is a crucial skill for any hacker who wants access to the latest technology via SMD modules or new SMD ICs. SMD ICs are incredibly small. Learning how to make footprints that work with these tiny part is a crucial skill.
What are the different types of SMD components?
SMT components or SMDs have a number of standardised packages including 1206, 0805, 0603, 0403, 0201, SOT, SOIC, QFP, BGA, etc. Surface Mount Technology, SMT Includes: What is SMT SMD packages Quad flat pack, QFP Ball grid array, BGA Plastic leaded chip carrier, PLCC. Surface mount technology, SMT components come in a variety of packages.
Where are surface mount components held in SMD?
Often the very smallest components are held loose in a hopper and these are fed down a tube and picked out as required. Larger surface mount components like resistors and capacitors as well as many surface mount diodes and transistors may be held in a tape on a reel.
Do you already have a ssop16 in your library?
To create a new package, type the name SSOP16 into the ‘New:’ box. This fits with the same naming structure as the SSOP20 package. Do you already have a SSOP16 in your library?
What kind of IC has 16 pins and a footprint?
This IC uses a package type called SSOP16 and has 16 pins. Wikipedia has some good information about SSOP (Shrink small-outline package) chips. For our purposes, we need only to get a short package identifier into Eagle. From within the Eagle footprint list, click on any footprint in this window and press ‘s’.
Where do I find the footprint for my PCB?
From within the Eagle footprint list, click on any footprint in this window and press ‘s’. This will bring you to the packages starting with the letter S. Now is your chance to see if the package you are about to create is already available. In our case, ‘SSOP20’ is available but SSOP16 (the 16 derivative) is not.
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.
