Once you upload the gerber files, you should reach this page shown below.
The following check is mandatory:
If your board doesn’t need extra features, please make sure you are not paying extras
- Via is at least tented. Upgrade to Epoxy Filled & Capped is available for free if board layer >= 6
- Change the stencil dimension to fit your board size, don’t use the default dimension as it adds shipping cost. Min via hole size/diameter is selected as 0.3mm/(0.4/0.45mm)
- Select HASL(with lead) for Surface Finish
For other parameters, you can leave the same as shown in the screenshots above. However, there are some parameters we suggest you to consider:
Board Color (Black might be free under unknown conditions)
If you need to change layer stackup, choose Yes for Impedance Control
Higher Inner/Outer Copper Weight increase PCB current carrying abilities
Remove Mark on PCB might be free under unknown conditions
For 6 layer (and above) boards, it forces you to select ENIG for surface finish which leads to around $60 extra.

Step 2B: Decide if we need Stencil

A PCB stencil is a thin, typically stainless steel or polyimide sheet, that has laser-cut openings to match the layout of surface mount technology (SMT) components on a printed circuit board (PCB). It is used in the assembly process to apply solder paste accurately onto the pads of a PCB before placing components.

Stencils speeds up the bringup process of SMT PCBs, but they also adds manufacturing and shipping costs. WARG orders them for most of our PCBs unless the PCB mainly consists of through-hole components like the image shown below.

Always check the PCB design in the JLCPCB gerber viewer when deciding whether to order stencils or not
