Guys!

 

Do any of you have good AWG and PCB Hole size charts you could share with me? I am looking for AWG lists and what hole size to use on pcb etc..

 

Thanks!

Are 
you talking about solid wire used on thru hole parts or stranded 
wire?

Jim,



 



I am planning to
use Stranded wire to solder onto pcb but I need to
know which hole size on the pcb we should use. You
know for example if I select 24 AWG wire and I know the size is .020 in
diameter but which hole size should we use on pcb? I am
looking for nice charts that contain #AWG, DIAMETER, HOLE PCB DIAMETER, PADs
size, VOLT, etc.. I have tried to search for them in google
but I couldn’t find any good charts that indicate which pcb
hole and pad sizes should be used.

Thanks Denis but
I already saw them and they are not what I was looking for.. I am looking for
both mech and pcb combined
in one chart where I can post it in my office. 
So I don’t have to google around next time.

Here is the data from "Handbook of Electronics Tables and 
Formulas" by SAMs publishing:  


 


To get the wire diameter in mils (0.001") take the square 
root of the circular mils value.  For example, 30 AWG has a diameter 
of 10 mils (0.010").  


 


AWG   Circular mils


32    
63.2


30    
100.5


28    
159.8


26    
254.1


24    
404.0


22    
642.4


20    
1022


18    
1624


16    
2583


 


And they keep going all the way to 0000 but we are 
starting to get out of the realm of PCB sizes.  This book has a really 
handy chart with current capability and resistivity too.

I think the only thing I would need a chart for is AWG to inches/metric conversion. Once I know the that size, .020 mil for example, I should be able to calculate the finished hole size from there. Am I missing something?

A chart you are asking for may not be your silver bullet. 
Here are a few things to think about -


 


Is the stranded wire bare copper? If so, will you solder 
coat it prior to assembly? If yes, what is the resultant max 
dia.?


 


Is the wire insulated or sleeved? what is the MINIMUM 
outside diameter of insulation/sleeving? Will it fall into the PTH and inhibit 
soldering? If you follow a predetermined wire/PTH dia. then insulation may 
possibly fall into the hole.  PTFE tubing, for 
example, comes in varying wall thickness for a given wire gauge. 
Consequently the PTH & its tolerance may have issues with the different wall 
thicknesses.


 


Do you order from multiple suppliers, and is every 
product's insulation identical in dimensions and tolerances, etc? If you 
select the maximums, do you then have issues with insulation in the hole with 
one versus the other supplier?


 


For hole diameter to lead diameter recommendations, refer 
to IPC-2222.


 


Just a few things to consider.......


 


Regards, Bill

Keep 
in mind that stranded wire is larger in diameter then solid wire. So you 24 ga. 
is some what larger then .020.


 


I do 
have a book that shows PCB hole sizes for different wire gages, but it is solid 
wire, and nothing I can e-mail.

Charts


Thanks 
Denis but I already saw them and they are not what I was looking for.. I am 
looking for both mech and pcb combined in one chart where I can post it in my 
office.  So I don’t have to google around next time.
