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.

This question is about the advisability of continuing to use a USB mini-B right angle surface mount connector in my pcb designs. On occasion we see one of these connectors peel back or delaminate off the pcb. Immediately the question is asked, why didn’t you use a through hole connector?
I have received PCB samples containing AC line. Test is indispensable process on my side to ensure its quality and function. But is AC line dangerous? How do I protect myself during testing?
I have two BGA parts on a PCB, with a 32 bit wide bus with a few control lines and a clock line connecting them. Almost all of these traces are only on internal layers. There looks like a signal integrity problem on the bus. The good news is that the board only has parts on one side, and all the vias are through-all. Can anyone suggest good ways to remove the tenting over the vias so they could be probed with an oscilloscope, or at least be able to solder 30 gauge wire to them?
