DirtyPCB has been around for quite a while now, and I gave them a couple of protopack orders way back in 2015. They are a part of Where Labs, LLC and therefore a subsidiary (partner? distant relation?) of Dangerous Prototypes. The DirtyPCB site has developed extensively since then with various manufacturing offers from laser cutting to SLA 3D prints, BOM management and, of course, PCBs.

DirtyPCB really goes out of their way to set your expectations as a customer: you should expect fully functional boards, but not exquisite quality, although sometimes exquisite quality might slip through.

Final cost for a 10 board “Protopack” in the 10cm x 10cm dimension [...]

Smart Prototyping, also known as NOA Labs, is a PCB fabricator and EMS located in Hong Kong and Shenzhen. Like many of their competitors, they provide a market place for the sales of open source hardware developed in-house and sold under the Zio and Qwiic brand names. While it has absolutely nothing to do with manufacturing, I was very happy to see that they actually published the design files and specs for their open source hardware on the Zio Github page.

As another relatively low cost fabricator, Smart Prototyping came in at $9.90 for 10 boards, 0.99USD per unit. This is the same per unit ball park as Shenzhen2U and ALLPCB. However, they charge a whopping $28.79 for [...]

ITEAD Intelligent Systems Co., LTD, also called Sonoff, is a Shenzhen based PCB fabricator and PCBA service provider. As is usual, they offer not only fabrication and assembly services, but also host a market place, the “IMALL” for boards sourced inexpensively in China or designed in-house. They also have a blog with over 450 posts dating back to 2010 that used to contain articles about things like hacking a Saleae Logic Analyzer but now is mostly about smart homes, IoT and stock photos.

The purchase price for whatever it was I purchased (as of the writing of this section, I still haven’t received confirmation that the order was for 1 or 10 boards), was [...]

Seeed Studio used to be known primarily as a retailer of Arduino clones, Raspberry Pi accessories and their line of “Grove” interconnecting breakout boards. They’ve grown out a circuit board fab, electronics assembly service, 3D printing service bureau and CNC Machining capability, and this Seeed Studio PCB Service Review will focus on their Fusion brand, targeted squarely at “global creative technologists”, independent engineers and tinkerers. While their headquarters are based in Shenzhen, they opened an office in San Francisco in 2015 and in 2017, opened offices in Nagoya, so they would seem to be trying to push the Seeed brand regionally through [...]
