OSH Park
US-made bare PCB prototyping service known for small orders in multiples of three and a medium-run option.
What they do
OSH Park sells bare printed circuit boards aimed at prototyping, hobby design and light production. Orders are placed online: a buyer uploads board files, gets a quote, approves the design and pays on the site.
Boards are made in the United States and ship from Lake Oswego, Oregon. The standard services cover 2-layer and 4-layer boards with purple soldermask and an ENIG finish, and the catalogue also lists flex boards and an After Dark clear-soldermask option.
Orders are sold in multiples of three, with a medium-run service for larger orders and Super Swift options for faster turns.
