DirtyPCBs two layer ENIG PCB closeups


The standard service is $14 for 10 boards. You can have the pads ENIG finished for $15 more, which brings the total cost to $29 for 10 boards, shipped. It is still an excellent deal. The quality is excellent too, as the closeups below illustrate.

Fig 1: The pads for this 0.5mm pitch QFN were solder mask defined in the design. 

Fig 2: Actual solder mask on the PCB. They expanded the clearance here by quite a bit, but this is perfectly reasonable. 

Fig 3: Tigher clearances here on this side.

Fig 4: 0.1 inch header - Drilled holes alignment are quite good. 

Fig 5: 1mm pitch Flat-flex connector pads. 

Fig 6: Pads for 0603s. To the right is a 2mm pitch, two-pin header.

Right! Fpgas are really awesome little things.

Unter den Funkamateuren gibt es einen Fertiger in DL: http://www.dh4ym.de/index.html Mal probiert oder in Erwägung gezogen? Es ist ja - besonders bei einfachen Projekten - nicht immer Doppelseitig oder ein Aufdruck nötig...

it would have been good if you should us a completely finished PCB, and if this set of solutions will only do about 5 or 6 boards it would be better to use another method
sounds like a waste of time and a lot of money!!!!!!!!!!!!!!!!!!

34 people watching this video have probably never made a DIY circuit board. Watching this video make the process look really easy but it takes a lot of technology to make these kind of boards. Thank you for this informative film.

Every bare printed circuit board gets some sort of surface finish to protect the copper traces from oxidation until the board can be populated and soldered to create your finished PCB assembly. In this video we take a quick look at four of the most common lead-free surface finishes (HASL, Immersion Tin, Immersion Silver, ENIG) and when to use them
