SeedStudio offered me a coupon to evaluate their PCB service “Fusion“. I am currently working on a new project, so I gave this service a try. I used the following options ordering the two boards:

PCB Dimensions 68mm*108mm
Impedance Control No
Surface Finish HASL Lead Free
Minimum Solder Mask Dam 0.4mm↑
Copper Weight 1oz.
Plated Half-holes / Castellated Holes No
Minimum Drill Hole Size 0.3mm
PCB Color Blue
Base Material FR-4 TG130
No. of Layers 2 layers
PCB Quantity 5
Blind or Buried Vias No
PCB Thickness 1.6
Trace Width / Spacing 6/6 mil

I payed $27.40 for five boards with the option shown above and there were additional $20 shipping costs.

My board design has a very low quality class B4: Minimum drill size is 0.35mm, minimum trace size and spacing is 0.2mm.

Ordering and Shipping

The order process was very simple. The website provides an assistant with all possible options and calculates a quote in real time. I just noticed these minor things:

  • The shipping cost is not displayed in this quote.
  • The dimensions were not correctly extracted from my Gerber files.

The production of the boards and the shipping was quite fast, the whole process only took 10 days until the packet with the boards arrived.

The boards were well protected in the package, so there were no scratches from the shipping of the boards.

Quality

The boards have a good quality for the chosen options and the price. The alignment of the layers is not perfect, but everything is in an acceptable range.
