(2) general precautions for use chips should be stored in a clean environment. if the chips are to be stored for 3 months container with nitrogen gas injected. (shelf life of sealed bags : 1year, 0~40 c of temperature , 20~70% of rh) this chip should not be used directly in any type of fluid such as water, oil, organic solvent, etc. when washing is required, ipa is recommended to use. after storage bag is open, device subjected to soldering, solder flow, or other high temperature processes must be: mounted within 168 hours (7days) at an assembly line with a condition of no more than 30 c and 60% rh must be baked for 24hrs. at 65.5 c, if baking required. chips require baking before mounting, if humidity card reading is >60% at, 23.5 c. chips or more after being shipped from marktech , they should be packed by a sealed 6

(3) precautions for die attach (pick and place) unlike the top of chip, the bottom (the opposite side of sapphire substrate) is the epitaxial layer where the p-n junction is located. it is not mechanically protected and can be damaged if a sharp and hard ejector pin material is used . seoul viosys recommends an ejector pin with rounded edge to minimize the risk of mechanical damage. (a) (b) (a) sharp ejector pin tip may damage the flip chip (left). (b) a rounded tip m in imizes the risk of damage caused by ejector pin (right). 7
