Hello there,
I have a component with 2 eyelets termination. THe two outputs are to be
connected to another component. As you can see, to do that, the only way
is to solder a wire each to the eyelet and terminate it to a PTH hole
on the board.
Now, here come the questions :
(a) should I just provide a PTH pad directly beneath the eyelet termination
- to allow the insulated wire to bend like a little "J". One end solder
directly to the eyelet while the other end soldered to the board via the
PTH hole,
(b) 2 holes : one NPTH and one PTH
- to allow the insulated wire to make a loop through the board before
soldering one end to the eyelet termination of the component and the
other to the PTH pad.
Idea (a) will have saving in space and I think the termination method is
reasonable enough. While idea (b) require space.
I cannot find anything reference in IPC-CM-770 that address such
termination. In IPC-2221 Figure 8-31, there is a diagram for power
module using jumper. Is it applicable to this eyelet termination
component, too?
If I am to use (a), I will include sleeve at the eyelet termination
similar concept of harness. I don't think I am over doing it., right.
Hope to hear from some of you what connection method is the most
effective or appropiate for such eyelet termination component.
Thanks and regards,
Wee Mei
