Component Packages

Overview

Most electronic components come in standardized packages. A package type has well a defined set of physical dimensions that the component has to conform to. For each package, normally the pitch spacing, height and general shape is defined. However most packages contain variants with a differing number of leads (for example the classic old-school DIP package comes in 4, 8, and 10 lead variants just to name a few). This means that total land area and size of a package can vary according to how many leads it has.

Standardizing components sizes and shapes makes it easier for the component manufacturer, the PCB manufacturer, and the design engineer. Although most components are standardized, there are still plenty of packages out there. This pages purpose is to hopefully make some sense of the most common and widely used packages and to help anyone choosing a component package or designing a PCB.

Component Package Database

Packages are listed alphabetically.

All land-area (occupied PCB space) calculations are based around the minimum-sized square that encloses the entire package. This does not take into account the size of the pads required on the PCB, which would increase the calculation by a small amount. Nominal package dimensions used for calculation. All 3D models are from http://www.3dcontentcentral.com.

Component packages with many names (synonyms) are listed by the most common, or most “popular” name, which is not necessarily the technically correct name.

Some items such as the PP3 9V battery case, and SIM card sizes, may not be strictly component packages, but are included here for completeness.

Break-out Boards

Break-out boards are useful for converting one package footprint into another. They are particular common for converting smaller SMT package footprints into 100mil DIP packages for prototyping with modern IC’s.

If not brought from the right place, these break-out board’s can be very expensive!

SparkFun is the cheapest supplier of break-out boards that I’ve found. Element14 also sells them, but at a much higher price.

Fairchild Surface Mount Packaging Information – An extensive database of most surface mount footprints and their variants that are out on the market. Each footprint has a pdf with a technical drawing of the package and a recommended land pattern (the dimensions and orientation of the pads you would use to make the PCB). Although this is made by Fairchild, since the packages are pretty standardized, this should apply to any manufacturer. Although just to be on the safe side, use the actual manufacturers data if they supply it (some don’t and most make it incredibly hard to find).

3D models (which can be imported into Altium as step files) can be downloaded from 3D Content Central (www.3dcontentcentral.com). It is a combination of content submitted from both users and suppliers, can contains many standard component packages in 3D.

SiliconFarEast “IC Package Types” (http://www.siliconfareast.com/ic-package-types.htm) – A short but tidy graphical table describing most footprints. Also has data on the body size, body thickness, and lead pitch for the most common variants of each package.

The SMT Code Book (http://www.marsport.org.uk/smd/mainframe.htm) – Handy database for working out what small SMT components are. Since there is usually not enough space to print the entire part number, most manufacturers print their own kind of code of small SMT components. This makes it really hard to determine what they are. To make matters worse, many manufacturers use the same code for different components, and sometimes the manufacturer releases two components with the same code! The trick is to be able to identify the package and the code, and together you can get a good idea of what the component is. The SMT Code Book lists over 3,500 SMT device codes in alphabetical order.
