content: For a product i'm designing i need some medium power rgb led but the problem is that the direction of the light must be perpendicular from the board (sorry for the bad english..).I only found thishttp://www.kingbrightusa.com/product.asp?catalog_name=LED&product_id=APFA3010SEEZGQBDCbut is not very powerful and the price is a little too high.I don't have experience in large quantity pcb manufacture and i would like to know if assembling the board (all smd part and on one side) with the smd led (expensive) is still cheaper than using a normal trough hole led (cheap) that someone should bend and solder.Thanks for the help.

content: Physically bending and forming a lead on an LED is labor and that will cost you considerably (relatively speaking) - even if it didn't require custom bending, the fact it is thru-hole is another process and will add to assembly costs.There are actually a lot of right angle LEDs both SMT and TH. Are you looking for a color LED for indicator purposes?

content: If it's a chip LED, perhaps you could stand it on its side to solder in place.

content: There are plenty of side-view SMD LEDs available. Not so many in RGB, but they exist per my first post above.

content: Have you considered using light pipes?http://www.digikey.com/product-search/en/optoelectronics/optics-leds-light-pipes/524541They may not be easy to install with an automated process but you may be able to source some "snap-in" type, or press fit.. so you wouldn't have to solder anything and it wouldn't add a lot of time to assembly.it costs a bit of money, but on the other hand you'd use some more common rgb leds, less expensive, easier to source etc....
