Seems as clearance defined to ground plane is quite small, particularly close to components Pads, which eventually could have a solder drop spreading beyond their unmasked region.

Hi,

Thermals are switched off. This makes soldering by hand difficult.

1\Shape thermal relief orthogonally connects to SMT pins, through pins, that would be best;
2\Shape clearance in the range of 0.3~0.5MM is perfect;
3\you can use thick lines, big vias. to save costs

The clearance is 6 mil between lines and shapes. For soldering, it is no problem. I have soldered a lot this kind of boards by hand.

Thermals are the gaps to the signal plane connections. You don't use it. Be sure this is what you want.

Hi guys, thank you so much.

I have changed the design as folllows;
(1) Thermal relief connect setting: Thru pins: Diagonal; Smd pins : Orthogonal; Vias: Full contact;
(2) I have checked the BBB design. It's clearance between lines and shape is 5mil. So I might keep mine as 6mil.
(3) The line's and visa's size already match the pcb factory's minimal requirement. If I increase them, it still not save money. Anyway, still thank rube so much for your valuable suggestion.
