No. It is entirely up to the component manufacturer. When the PCB is manufactured, some companies will ask that component placement overlays be given. Designators are provided. And polarity marks for all polarized components are shown.
It’s also a good idea to make a couple of test boards and hand solder and get familiar with the components to identify this kind of issue, prior to sending in large batches to get assembled.

I’m designing a new PCB where I have a whack of connectors that have to line up with the metalwork. There are some problematic connectors. All 4 pins are round. I want to have the holes as small as possible while allowing for good solder adhesion over the full length of the pin. I’m looking for guidance on how much clearance around the component lead I should have in order to get good solder wetting and adhesion.
Hello, we have never visited your company. Could you please tell if you are trading company or self-own factory? It will affect the difficult level of our supply chain management.
I’m designing a two-layer PCB and I’m very inexperienced. A third-party company will fabricate them. Now, I have a PTH part with a number of closely spaced pins. However, I can’t greatly simplify routing by running traces unless I eliminate the pads for certain pins on one side of the board. So can I leave a through hole pad off one side of a machine-fabricated PCB?
