● OSH Park is a community PCB ordering service started by James “Laen” Neal
● We bring you high quality, lead free boards (ENIG finish), manufactured in the USA, and shipped for free to anywhere in the world.
● The company grew out of an electronics meetup in Portland named Dorkbot PDX
● “OSH” is a reference to Open Source Hardware● Projects can be shared on our site but all
projects are private by default
● We take designs from lots of people, put them together on a panel, and order panel from a fab
● Since we're all splitting the panel setup cost, this lets us make circuit boards inexpensively.
● 2 layer boards are $5 per square inch – with 3 copies of your board included in that price– ship in under 12 calendar days from ordering.
● 2 layer Super Swift service ($10/sq.in.)– guaranteed to ship in 5 business day
● 4 layer boards are $10 per square inch– includes 3 copies of your board– orders are sent to fabrication every other day, and
have a turn time from the fab of one week.
● Discounts for larger 2 layer and 4 layer orders● Full list of offerings on Pricing & Specifications

● Design Rule Check (DRC)– We provide Eagle Design Rules files and we highly
recommend you clear any overlap, dimension, and clearance issues before uploading a board.
– You can ignore DRU errors on the tStop and bStop layers since we automatically prevent silk from being placed on exposed copper.
● Design Rule Check (DRC)– Download our Design Rules for EAGLE (.dru files):
● 2 Layer: oshpark 2layer.dru● 4 Layer: OSHPark 4layer.dru
– After downloading the file, you can load it under Tools > DRC > Load, and then selecting the appropriate file
● Design Rule Check (DRC) User Settings– In addition to manufacturing requirements, the DRC
settings also contain a few user-selectable settings which might be helpful.
● Design Rule Check (DRC) User Settings– Clearance > Same Signals
● These settings can be reduced to 0 to prevent warnings about placing vias close together, or placing vias next to a pad.
– Restring >% and Restring > Max● These can be adjusted to changed the proportions Eagle uses when
placing through-holes. Min can be increased, but should not be below 7mil.
– Shapes:● This adjusts the curvature of SMD footprints and “long pad” through-hole
footprints.
– Supply:● Should be at least 6 mil.
● Design Rule Check (DRC) User Settings– Masks > Limit:
● This setting allows you to “tent” vias, and cover them with stop mask.● Eagle will cover any vias below the Limit with stop mask, and will only
expose vias larger than Limit.● If you want to expose a specific via below the Limit (for example, test
points), you can check the Stop setting in the Properties menu of the via.
● Typically, a good value for this is either around 20-30 mil, but it will vary by design. Our stock CAM settings have it set to 0 to disable via tenting.
– Misc:● All options here are adjustable.
● Design Rule Check (DRC)– While uncommon, we may occasionally update our
DRC settings as we improve our specs.– You may want to periodically update your .dru files,
or use our Eagle Tools to help manage them.
● OSH Park Eagle tools– These scripts are to help Eagle users get orders in
just a tad bit faster, and help keep your Eagle files a bit more up to date.
● OSH Park Eagle tools– Add a menu button to enable easy PCB ordering
right from inside Eagle.– Update your OSH Park CAM, DRU, and ULP files.– Manage version-specific differences for CAM or
DRC files.– In the future, we'll be adding improvements to the
script to hopefully add better integration and cool new feautures.
