Have a problem with PCB design?
What is the correct way to draw the silkscreen on the bottom side?
The bottom silkscreen text should be reflected (mirrored). The most PCB design software will automatically reflect the text for you but please make sure this is the case in the Online Gerber Viewer or other viewers.
My PCB does not require Solder Mask, what should I do?
Unlike the copper layer, the solder mask layer is negative. This means a solid object in the layer corresponds to a hole, or opening in the solder mask layer (an area without solder mask covering). Therefore, for a board that requires the surface to ...
My PCB does not require Drill Holes, what should i do ?
A drill hole layer is mandatory in all PCB orders. If your PCB does not require drill holes, please do not exclude the drill layer. If possible, please include an empty drill layer in your files and a drill report indicating that no drill holes are ...
Which layer should I use in EAGLE for milling?
In Eagle, when using our CAM file, you can add milling data to either the dimension layer (layer 20) or the milling layer (layer 46). Both will export to the mechanical layer.
I don't want silkscreen on my PCBs, how can I proceed with a PCB Assembly order?
For Seeed Fusion PCB Assembly (PCBA) orders, we need to know where to place the components. If you do not want silkscreen on the finished boards, please provide another means of identifying the location and orientation of the components. This can be ...
How do I design non-plated through holes/slots?
To ensure that the mechanical or mounting holes/slots are not plated, there should not be any copper around the hole in the design files. Plated holes/slots: Circuit layer: holes have copper Solder mask layer: holes have openings Non-plated ...
How do plated through holes/slots shows on the Gerber?
Step 1. Put copper pads on top and bottom solder mask layers. Step 2. Put milling slots in the mechanical/outline layer. Plated holes/slots: Circuit layer: holes have copper Solder mask layer: holes have openings Non-plated holes/slots: Circuit ...
