Utility for package creation

Does Eagle have a utility for the creation of typical packages?

 

I'm looking for something that you input pin pitch, row spacing,

total pin count, and other standard dimensions and have the program

generate a good starting point. I tried the createsymsmdpackage_rel2

ULP but it aborts with a syntax error (Eagle version 6.2).

There is an error in the CreateSymSMDPackage_rel2.ulp and associated file

that you can correct to make this ulp run.

The problem is a variable name in the ulp that equals the function name of a

new function that arrived with v6.

i.e. mic2u

In the following files find the instances (5) of mic2u and replace with

Mymic2u

globals.hul

functionMisc.cul

I didn't test beyond getting the first dialog to open but looks promising.

After you get a package created, measure it to be assurred it is the correct

size.

Good luck.

I wrote some simple C programs that prompt some questions about the desired package, and it will auto-generate an EAGLE script file.

It was only for personal use, but maybe you may wish to use them, or adapt for your purposes.

It is quick to use, and I use it all the time now, instead of manually creating packages.

It only does it for surface mount (because that was all I needed) but could give you ideas for through-hole too. If you do enhance it, please share the source and executable (and maybe even the generated script files) with others : )

It works for all dual-in-line style SMD packages (SOP, SSOP, etc), quad packages (QFP, etc) and also single-in-line style packages (e.g. flex cable connectors). For example, if you run it as shown here (it provides "hints" to help answer the questions it asks), and respond to it at the '>' prompts:

** SMD Tool ***
All dimensions in mm
Pad width
---------
TQFP:0.29 TSSOP:0.40
>0.5
Pad height
----------
TQFP:1.35 TSSOP:1.30
>1.2
Style (number of sides)
-----------------------
TQFP-like:4 TSOP-like:2 SIL-like:1
>2
Distance to opposite side pad centers (Ax or Ay)
------------------------------------------------
TQFP48:8.45 TSSOP:6.10
>3.1
Pin spacing/pitch (e)
---------------------
TQFP:0.5 TSSOP:0.65
>0.95
Number of pins
--------------
TQFP48:48 TSSOP16:16
>6
Overall package width
---------------------
TSSOP16:5.0
>2.9
Filename
--------
example: my_tssop.scr
>my_tsop6.scr

Then, the generated script file will contain:

wire 0.127000 (-1.450000 -0.569000) (1.450000 -0.569000)

smd 0.500000 1.200000 '6' (-0.950000 1.550000)

And when you run that in EAGLE (create a Package as normal, then select File->Script), it will generate the package:

Here are some other examples that are possible:

Nice web page resource, thanks!
