Precautions in Use: PLEASE PAY SPECIAL ATTNTION TO THE NEXT POINT TO INCORPORATE OPTO DEVICE TO HIGH RELIABILITY 1. Do not bend the lead. Bending leads could cause breakage of leads or the degradation of the chip. When bending is unavoidable, strictly follow the cautionary instruction below. (1)Bend the leads before soldering. (2)Bending a lead must be done by fixing a lead tightly and applying no stress on the resin part. (3)The lead bending point must be more than 1.6mm away from the edge or the resin part. (4)When a pin is tested for its endurance, bending degree should be repeated no more than two times. 2. Setting a product by using tool such as a holder should be avoided. When necessary, no stress should be applied to the resin part and lead to consider dimension tolerance, thermal expansion, thermal contraction of holder, product and circuit board etc. 3. The hole pitch of a circuit board must fit into the lead pitch of products. 4. When soldering, care the followings: (1)Do not heat a product under any stress (i.e.: twist) to leads. (2)Do not heat ( for example, by soldering ) a product while out side force is applied the resin part. (3)The temperature of a product should not exceed the specified maximum storage temperature. (4)Soldering with PC Board should be conducted with following conditions. (a) For dip soldering Pre-heating : 90 Max. for within 60 Sec. Soldering bath : 260 5 (Solder Temp.) for within 5 Sec. (b) Soldering iron : 350 (Soldering iron tip) for within 3 Sec. 5. Flux could corrode the leads.use flux that contains as little chlorine as possible (RA, RMA, less than 0.2 wt%) and need not be washed way. When, however, washing is necessary, partially wash around the leads, instead of the entire LED, by the following conditions. Cleaning agent : Methyl Alcohol Cleaning temp : 45 MAX. Cleaning time : 30Sec. MAX. 6. Minimum amount of soldering flux should be used. Soldering flux should be applied only to the pin portion. 7. The following may damage products or LED chips: Attachment or contact of residual flux solvent onto the product surface or to LED chips, or invasion of the same into the product.
