You don't need slotted holes for it, but it will take a lot of solder and a lot of heat to properly solder it if you don't use slots. Could have process issues if this item is going to be manufactured - talk to your assembly house. > If so, then are routing commands portable with the component or will > they have to be on the laid board ?

See this conversation: http://forum.sparkfun.com/viewtopic.php?t=5983 Keep in mind that many board houses charge more for or do not allow interior plated routing, and especially stepped drilling (mouse bite routing) like this - if it's a slot it needs to be routed. If you use multiple drill passes you raise the risk of breaking the bits. Talk to your board house. Alternately, do the reverse. Specify it as a single plated hole in Eagle (and thus the gerbers), and then send special instructions to the board house that it instead be a plated slot with specific dimensions. Make sure you have a clear fab drawing of the entire PCB with the called-out locations of board edges and the slot dimensions and orientation so it's absolutely clear. Either way, I'd start by talking about it with the board house to find out your options and the possible extra charges, before you do a lot of work in Eagle. It may be cheaper to specify it on a drawing than it would be to have them convert a mouse-bite slot in the gerber into a real routed slot. -Adam -- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Moving in southeast Michigan?
