thestruggler Posted May 27, 2007 Report Share Posted May 27, 2007 Hi,Another silly one really. The PCB's i purchased have really small holes for the 4 corners, same size as the legs of the componenets. I cant seem to figure out to fix them to a case?? Also would be handy to be able to take them off if the magic doesnt happen and it doesnt work??Thanks...from miserably rainy london. Quote Link to comment Share on other sites More sharing options...
DavidBanner Posted May 28, 2007 Report Share Posted May 28, 2007 mmm, that's an odd one!don's suppose you have a dremmel handy? you could mill out the holes to a more agreeable size (use googles and dust mask) Quote Link to comment Share on other sites More sharing options...
Sasha Posted May 29, 2007 Report Share Posted May 29, 2007 You really need to have any kind of drilling machine if you building any of MB projects. Quote Link to comment Share on other sites More sharing options...
thestruggler Posted May 29, 2007 Author Report Share Posted May 29, 2007 I have a drill...but seems to be a drastic measure with them all already being stuffed... Quote Link to comment Share on other sites More sharing options...
DavidBanner Posted May 29, 2007 Report Share Posted May 29, 2007 how else are you going to mount them?btw:you'll need a high speed drill (i.e. 33,000 rpm) and tungsten carbide drills Quote Link to comment Share on other sites More sharing options...
thestruggler Posted May 29, 2007 Author Report Share Posted May 29, 2007 i see your point. i dont really have a precision drill, but a plain ordinary one and what made me nervous to try that out.i dont have a board that i can try my drill on to see if that will work...am really tempted though ::) Quote Link to comment Share on other sites More sharing options...
Sasha Posted May 29, 2007 Report Share Posted May 29, 2007 Man, I think you need some more self esteem... There is nothing critical in drilling the PCB after all parts are mounted. You already have that small 1mm hole to guide the drill, if not drill it first with 1mm drill and afterwards with 3mm. I never pay attention on drilling those mounting holes before soldering. Sometimes I do it after I drill 1mm holes for components, sometimes before mounting the PCB. It really doesn`t matter. Sometimes I need mounting hole on some other place, not in corner of board. Just flatten your PCB onto some piece of wood and drill! Use sharp drill bit and hold your board and will be no problems. Relax, and do it. ;) Quote Link to comment Share on other sites More sharing options...
RTurner Posted June 3, 2007 Report Share Posted June 3, 2007 Every once in a while I'll forget to drill out a hole in a PCB. It happens. That's why you should get yourself a jewelers hand-drill. It's basically just a handle that fits small drill bits. But this way you can be reasonably sure that the only thing that will break is the drill bit. BTW, if you take this approach- be real careful with tungsten bits. they're brittle. It's often better to use steel bits for this reason.
