What is the maximum length of plated slot shown on this picture?
Some time ago I needed a 15mm plated slot, but manufacturer was unable to fabricate long plated slot even for additional cost.
What plated slot length accepted by most PCB manufacturers? Currently I need plated slots around 5mm in length on a 1.0mm thick FR4 board.

Looks like the latest fad in Bot spamming is to copy paste some old legitimate post ... which of course will "look Human" .... because it is.

can
be done, just your particular job falls out of standard and fabricator may not consider it worth doing, specially in this cutthroat competition market.

They usually depend on drills of various sizes, so round holes; that slot needs milling with the proper tool so it will have rounded ends or if made in large quantities PCB material may be heated and punched, creating any shape but needing specific punch/die sets .... expensive unless a lot are made.

Once you have the hole, any shape, it can go through the standard PTH process and be metallized like any other.
