Depends on volume...high volume, use a rectangular punch if you can.

Subject: [TN] Through hole dimensions for rectangular tags
Sent: Jan 4, 2010 6:23 AM

Hi, 



I have been seeking to try and standardise our through hole diameters in 

relation to the pins/battery tag size and in line with IPC recommendations. I 

have come across figures in IPC-2222 which outlines these sizes.  However…

These are only for round pin in round plated through hole. We are using 

battery tags of rectangular dimension 0.15x0.75mm. Taking the recommended 

dims for the round pin and applying it to our tag will mean that there is a 

greater volume of solder in the through hole. 

 

Does anyone know if there is a standard refering to this scenario? 

Should the through hole be made rectangular/oblong to accommodate this tag 

shape?



Any information would be much appreciated



Regards

Richard
