Share Light and Miracle with us □ What’s difference between CSP and PLCC LED PKGs?

CSP Flip chip

PLCC PKG Lateral chip



Lead Frame

SILICON + Phosphor(Yellow area)

Solder

PCB

Reacting Ag + Sulfer : yellowing possibility

Complicated Heat transfer

Wire bonding

malfunction possibility



No Ag Leadframe = no yellowing

Simple heat transfer structure

No wire bonding

Flip chip : High efficacy



CTLAB

High performance junction down chip

Share Light and Miracle with us □ CSP – TIR lens : Best combination !!

TIR LENS

Unit CSP Multi CSP

TIR LENS

• TIR : Total Internal Reflection -> Good for narrow beam angle


Share Light and Miracle with us □ Applications : Car Fog Lamp

SW1515QS X 4 6V 800mA 600lumen

Semi Omni directional CSP LED emitting structure is good for reflector design !!


Share Light and Miracle with us □ CTLAB’s core competitiveness

□ Manpower : CTlab Secure highest level LED engineer

All of engineers have over 5~7years experience in LED field(include CEO)

□ Technology : Ctlab has developed & produced CSP over 5 years

16 registered patents

LM80 certified on 2013

Variety CSP module developed (SW series, RW series, TW series, CW series)

CSP producing Knowhow from 2013 (Established 2012)

□ Market : Many of LED applications adopt CSP instead of Leadframe LED

Many of TV manufacturing company adopt CSP as Light source at BLU(CSP market is expanding)

mobile flash adopt CSP = CSP is Thin & tiny

High power LED demand is expanding(Exterior Lighting, broad cast Lighting, Automotive)

-> CTLAB takes the head in CSP LED technology & product based on Flip Chip
