Our manufacturer in Mexico has the following requirements for radial 
     through hole parts:
     To be auto-inserted, the pin pitch must be a min. 5.0mm.  The diameter 
     of the part must be min. 3mm, max. 14mm (13mm for elec. capacitor).  
     The height of the part must be min. 6mm, max. 21mm.
     Radial Insertion machine can insert the part if there is a 0.5mm 
     opening around the part body.  Also, obtain the minimum dimension 
     below for the spacing between radial parts' holes.
     
      - O---O                       
      ^                             
      2.5mm(3.0mm)                O 
      v                           | 
      - O---O         O---O       O 
            |< 3.0mm >|   |< 2.5 >| 
                            (3.5)   
     
     The values in parentheses are for transistors.
     
     Also, our manufacturer in Taiwan has the following requirements for 
     spacing between radial through-hole parts and SMT parts:
     1.27mm min. spacing between the outer edge of the radial part and the 
     edge of the SMT pad.  2.54mm min. spacing between the center of the 
     radial part's holes and the edge of the SMT pad.
     
     Not everyone has the same requirements, but I hope this is of some 
     help.

Hi to all!

This is a great place to get excellent information.  I need some 
info ASAP.  I'm working on a board that is going to be manufactured 
over-seas and can't get this information from that manufacturer.  I 
have some good guidelines for auto-inserting axial components and 
DIPs, but I need to know the spacing requirements for radial 
components (caps, transistors, 1/4W & 2W resistors that are stood 
up).  Can anyone help me out?

This board also has to meet UL approval per UL/CSA/CE/VDE for 
250VAC.  I am using 100mil trace widths with 100mil air gaps 
minimum, sound good to you?

Hope you don't mind all my questions.  More than that, I hope you 
don't mind answering all my questions because I'm sure I'll be 
asking alot more.  That's what we're here for, right? 

				Thank You again!
