Hello Fred, If we're talking single sided, rectangular holes can be done, but the hole will be punched. Therefore you need a die, which is custom-built and can be costly. If the hole will be PTH'ed, perfectly rectangular holes aren't doable. The hole wall needs a clean surface in order for the plating to bond with. And a clean hole can only come if its drilled. Punching leaves a rough surface which is unsuitable for plating. I've heard of holes being laser-drilled, but I'm not going there, at least not in the immediate future. regards, bambam fred de melo Sent by: To icu-pcb-forum@xxxxxxxxxxxxx 09/27/2004 06:45 cc PM Subject [PCB_FORUM] drill hole... Please respond to icu-pcb-forum@fre elists.org Hi, I use Allegro Design Expert and I wanna create a padstack for a special connector. Well, I want to know if it's possible to design a pad with a rectangular drill hole... I have imagined a solution : I enable multiple drill and make a row of circles...But it's not exactly what I want...
