Maybe you are frustrated about why your PCB design required to be changed on factory side, but I want to say this is a frequent and common thing in the PCBA OEM market.
Actually, they are checking on Design For Manufacturability (DFM), which can avoid lots of problems during manufacturing. It costs extra time and energy for them to run it through, but is very important to lay a solid base for further procedure.

I noticed that most PCB and components on it are conformal coating. Is that a necessary process for all the PCB in other field? What are they for?
I have three through-hole PCBs that are missing front and back solder mask openings for two of the components. The solder mask (usually green) is covering the front and back solder pads. All other pads for all other parts are exposed. Is there a good way to remove the solder mask so that I can solder the components to the board?
When I visit the PCB showroom in factory, I find that there are some pcs with round corners. Is it better to have round corners on a PCB?
