Package Information Recommended Chemicals for Cleaning/Degreasing The RoHS-compliant transmitters and receivers are Alcohols: methyl, isopropyl, isobutyl. housed in a low-cost, dual-in-line package that is made Aliphatics: hexane, heptane. of high strength, heat resistant, chemically resistant and UL 94V-O (UL fi le # E121562) fl ame retardant plastic. Other: soap solution, naphtha. Both the transmitter and receiver are coated with a layer Do not use partially halogenated hydrocarbons such as of conductive alloy for better air discharge (ESD) perfor- 1,1,1 trichloroethane, ketones such as MEK, acetone, mance. The package is designed for auto insertion and chloroform, ethyl acetate, methylene dichloride, phenol, wave soldering so it is ideal for high volume production methylene chloride or N-methylpyrolldone. Also, Avago applications. Technologies does not recommend the use of cleaners Handling and Design Information that use halogenated hydrocarbons because of their potential environmental harm. When soldering, it is advisable to leave the protective cap on the unit to keep the optics clean. Good system performance requires clean port optics and cable ferrules to avoid obstructing the optical path. Clean compressed air often is suffi cient to remove particles of dirt; methanol on a cotton swab also works well. CAUTION: The small junction size inherent in the design of these components increases the components’ susceptibility to damage from elec- trostatic discharge (ESD). It is advised that normal static precautions be taken in handling and assembly of these components to prevent damage and/or degradation which may be induced by ESD.
