SMD LEDs

LED die Cathode mark

Gold plated copper

Product description

Half moon shape provides more surface

area for adhesion

Context: ▪ 1206 package LEDs standard for dot adhesive dispensing of the MSM industry▪ Market constant need for a reduced height▪ Indoor bright in standard colors

Identification:▪ Standard 1206 LEDs are 0.75 – 1.1mm height▪ Dedicated 1206 LEDs to MSM are 0.35 – 0.5mm height

Product range:▪ Single color LEDs: green, yellow, orange, red, blue & white▪ Bicolor LEDs available

Technology input:▪ 1206 size package (length & width)▪ Overall dimension = 3,2 x 1,6 x ht.

Product description

Dedicated MS SMD LEDs offer:

▪ Reduced height! = less material expenditure & reduce embossing▪ Can use standard pick and place techniques

They do come at a premium price level and can be anywhere from 25% to As much as 3 times the cost of standard SMD LEDs from traditional manufacturers
