Quick-Turn PCB shop review project: ShenZhen2U

-March 14, 2016

I'm wrapping up my PCB fab review series back in China, with a look at board house ShenZhen2U.

The base price for five or ten double-sided boards (only the shipping cost changes) is $11.90 (10 × 10cm maximum). Including registered airmail shipping, it cost $24.70 for 10 of my 6 × 6cm test boards.

6/6 rules are standard. Options include 4-6 layers, various surface finishes & board thicknesses, and rush processing.

The silkscreen is good. Unfortunately, my haphazard photography setup makes it hard to discern the soldermask coverage. There does appear to be a thin sliver of it between the SSOP20 pads.

 

 

The wide soldermask clearance is easily visible here, as are the indentations from the flying-probe tester. A few of the boards sported some pads with excess solder. This is the worst example – not a problem in most cases.

 

 

Drill registration is very good.

 

 

No problems with trace/flood interaction.

 

 

 

Traces look good; perhaps a bit under-etched.

 

 

I'll be posting a final summary comparing the four PCB shops I reviewed soon.
