agree, light pipes from the panel, and/or add some egg crate louvers into 
the case to channel the light . Trying to build up solder height will just 
result in the part tilting. This should be a challenge for mechanical 
design, not board assembly.

Steve,

Maybe a Light Pipe? If the area is dense, you may not have room for the 
posts.
If you do find a way to do this, I'd certainly be interested in hearing 
about your solution.

Best of Luck,

Steve

Good Morning:

      We have an application here where our customer wants us to place two 
different height 0603 LED's (.027", .037") at .150" above the board. I'm 
thinking they want to do this to allow the LED's to protrude through an 
opening in a mounted front panel. The area where the parts are populated 
is very dense and I'm thinking my only option is to maybe purchase some 
high temperature solder blocks to put under the terminations to get to the 
desired .150" dimension. First of all, I'm not sure if this is even 
feasible and secondly, I was wondering if anyone has come across this and 
could offer some help. Thanks in advance.

Regards,
Steve Vargas
