	Your PCB house will mill the oblong hole accordingly. Normally the rule applies: "As long as the copper around is bigger than the drilling (a so called rest ring remains), the figure gets plated through." This is not always the same with milling. Because it depends on the question when the milling will be done: Before the plating or afterwards. Regarding the "plating through" in this case please contact your PCB house how they handle such. Maybe you should add a little explanatory text in respect to the milling here.		Your PCB house will mill the oblong hole accordingly.

	An oblong hole is a "[[Drillhole]]" brought to length. Others call it a slotted drill or a slotted hole. It is manufactured either by nibbling (an iterative number of drills in the dimensions of the desired slot) or by a milling tool. Such tools at least shall be 1 mm strong. In consequence the slot preferrably should be 1 mm wide. Smaller slots are difficult to create~~. In general please define millings in TARGET 3001! on layer ''25, Milling'' or on layer ''23, Outline''. Outlines get milled anyway~~.<br><br>		An oblong hole is a "[[Drillhole]]" brought to length.
