Multitude of colors sometimes at the same cost as the standard green. Sure you know, solder mask resist now comes readily available in a wide If they suddenly switch to a special solder mask color, then they need to clean the silkscreens or set-up a new station, especially for this order. If one needs extra solder mask coatings, then the whole panel goes along for the ride.Įssentially, they have no capacity to produce them and are simply not interested in the extra effort. So if one customer’s design needs a special color, then all the boards on the panel will have that color. That means everything is handled on a panel-by-panel basis.

In the typical PCB production process, everything is processed together until they are milled apart – one of the final production steps.

But after enquiring at various fabs, the scale of his proposal quickly sunk in.īasically, you are not going to be able to achieve any kind of custom solder mask design with the cheaper quickturn factories – the kind that panelizes orders from different customers together to save on materials and handling steps.

With help from a designer, Seeess had the Gerber files ready for his three tone boards. This time, fully aware of Defcon’s high standards, Seeess decided to fork out the cost and effort for an awesome badge design. Prior to coming to Seeed, Seeess had tried other fab houses for the previous badge runs. We also have an assembly video to top things off.

Particularly, regarding the vibrant design for the PCB nerds out there. Having had a personal input in the preparation and manufacture of these boards, I thought it would be neat to share some of the challenges Seeess and Seeed Fusion faced in the production of these boards. SAO, great for randomly adding blinky scallions to other Defcon badges. Combined with the simplicity of the circuit, it makes a neat little Striking aspect about this badge has to be the bi-color custom solder maskĭesign.
