Guest jimminy Posted February 13, 2004 Report Share Posted February 13, 2004 Can someone tell me what the typical hole spacing is for PCB's? I want to design my front panel but I don't know what the module needs to be.Thanks! ??? Quote Link to comment Share on other sites More sharing options...
Captain_Hastings Posted February 13, 2004 Report Share Posted February 13, 2004 What do you mean by PCB spacing?Do you mean the spacing of the holes on vectorboard? (2.54mm or 0.1 inch)? Quote Link to comment Share on other sites More sharing options...
Guest jimminy Posted February 13, 2004 Report Share Posted February 13, 2004 yeah, I mean the holes. I've never doen anything like this before, so I'm trying to figure out how to align my front panel cutouts so that when I mount everything onto a vectorboard it all lines up.I see why you ask, PCB isn't the right term. I guess it's vectorboard. Whatever the stuff is that Thorsten used on his SID project.Thanks! Quote Link to comment Share on other sites More sharing options...
doc Posted February 13, 2004 Report Share Posted February 13, 2004 Hi,the spacing is (just like mentioned before) 2,54 mm or 0,1 inch.But be careful. For example: A switch is mounted on the pcb. Look where the shaft is. Dependining on how you mount it the space can be 1,27 mm or 0,05 inch !My tip:Plug the components on your vectorboard without soldering them an then count the "whole" and the "half" holes on your design. Then you can measure the exact inch value for mounting.If you layout your design with the pc, print it out and test it before making the panel !Hope this helps youDoc Quote Link to comment Share on other sites More sharing options...
arumblack Posted February 14, 2004 Report Share Posted February 14, 2004 i would do as DOC say's plug your components in the vectorboard without soldering(or really if you know the layout you want, just not the measurements yet, go ahead and solder. then if a pot or led or round button, measure the distance form center of one component to center of the next, and so on. then you know where to center punch to drill out holes, or where to put the centers in your CAD drawing. for square componentes you can do the same. just you need a square hole.If you are making your own, you can drill, and then use a Nibbler to square the hole.

goyousalukis Posted February 14, 2004 Report Share Posted February 14, 2004 Another tip, when I made my SID frontpanel - I used the layout that Thorsten made. Everything lined up perfect. You can cut and paste elements to get the design that you want. Then print it out. You can lay out your components on the vector board and then put your printout on top and see if evwerything is lined up.Justin Quote Link to comment Share on other sites More sharing options...
Wilba Posted February 16, 2004 Report Share Posted February 16, 2004 I used a 0.05 inch grid in a drawing package to design the front panel, making sure that component pins were aligned to a 0.1 inch grid.DO NOT assume your laser printed artwork is accurate, especially along the length of the paper (ie. the axis that goes around the roller). I observed such a large error that I've had to rethink how to make an accurate drill guide (and print my artwork). The printer is fairly accurate along the width of the paper. What I'm doing now to compensate is printing my wide SID frontpanel across three A4 sheets, along the most accurate axis, then joining them up. The error across the page length over the 5 inch height of the panel isn't that bad.So get a good steel ruler, print out a 1" grid and MEASURE!
