pcb stackup
Generate beautiful, precise SVG renders of printed circuit boards given a set of Gerber and drill files. Powered by gerber-to-svg and pcb-stackup-core.
Install with:
$ npm install --save pcb-stackup
example
$ git clone https://github.com/tracespace/pcb-stackup
$ cd pcb-stackup && npm install
$ npm run example

usage
This module is designed to work in Node or in the browser with Browserify or Webpack. The function takes three parameters: an array of layer objects an optional settings object and a callback function.
var pcbStackup = require('pcb-stackup')
var fs = require('fs')
var fileNames = [
'board-F.Cu.gtl',
'board-F.Mask.gts',
'board-F.SilkS.gto',
'board-F.Paste.gtp',
'board-B.Cu.gbl',
'board-B.Mask.gbs',
'board-B.SilkS.gbo',
'board-B.Paste.gbp',
'board-Edge.Cuts.gm1',
'board.drl',
'board-NPTH.drl'
]
var layers = fileNames.map(function (path) {
return {gerber: fs.createReadStream(path), filename: path}
})
pcbStackup(layers, function (error, stackup) {
if (error) {
throw error
}
console.log(stackup.top.svg) // logs "<svg ... </svg>"
console.log(stackup.bottom.svg) // logs "<svg ... </svg>"
})
API
If your board doesn't appear at all or looks weirdly distorted try rendering it
with the options {maskWithOutline: false}
or filling in gaps in the outline
with e.g. {outlineGapFill: 0.011}
.
developing and contributing
Clone and then $ npm install
. Please accompany all PRs with applicable tests.
Please test your code in browsers, as Travis CI cannot run browser tests for
PRs.
unit testing
This module uses Mocha and Chai for unit testing, Istanbul for coverage, and ESLint for linting.
$ npm test
- run the tests, calculate coverage, and lint$ npm run test:watch
- run the tests on code changes (does not lint nor cover)$ npm run lint
- lint the code (will be run as a pre-commit script)
integration testing
The integration tests run the example code on a variety of gerber files to
ensure proper interfacing with gerber-to-svg
and proper rendering of
different stackups.
$ npm run test:integration
- Open http://localhost:8001 in a browser
browser testing
Browser tests are run with Zuul and Sauce Labs.
$ npm run test:browser
- run the unit tests in a local browser$ npm run test:sauce
- run the units tests in several browsers using Open Sauce (Sauce Labs account and local .zuulrc required)
