3 handling versatile link components are auto-insertable. when wave soldering is performed with versatile link compo- nents, the optical port plug should be left in to prevent contamination of the port. do not use reflow solder processes (i.e., infrared reflow or vapor-phase reflow). nonhalogenated water soluble fluxes (i.e., 0% chloride), not rosin based fluxes, are recom mended for use with versatile link components. versatile link components are moisture sensitive devices and are shipped in a moisture sealed bag. if the components are exposed to air for an extended period of time, they may require a baking step before the solder- ing process. refer to the special labeling on the shipping tube for details. recommended chemicals for cleaning/degreasing alcohols: methyl, isopropyl, isobutyl. aliphatics: hexane, heptane. other: soap solution, naphtha. do not use partially halogenated hydrocarbons such as 1,1.1 trichloroethane, ketones such as mek, acetone, chloroform, ethyl acetate, methylene dichloride, phenol, methylene chloride, or n-methylpyrolldone. also, avago does not recommend the use of cleaners that use halogenated hydrocarbons because of their potential environmental harm. level 4 caution this bag contains moisture-sensitive devices 1. shelf life in sealed bag: 12 months at < 40c and < 90% relative humidity (rh). 2. after this bag is opened, devices that will be subjected to wave soldering, or equivalent processing (solder temperature < 260c for 10 sec) must be: a) mounted within 72 hours at factory conditions of 30c/60% rh. b) stored at 20% rh. 3. devices require baking, before mounting, if: a) desiccant changes to pink. b) if 2a or 2b are not met. 4. if baking is required, devices may be baked outside of tube for 20 hours at 75c. bag seal date: ______________________________________________________ (if blank, see barcode label) note: level defined by eia jedec standard j-std-020 mechanical dimensions horizontal modules vertical modules 6.86 (0 . 2 7 0) 1 0 .16 (0 . 400) 4 .19 (0 .16 5) 1. 2 7 (0 . 050) 2 . 54 (0 .1 00) 0 . 5 1 (0 . 020) 18.8 (0 .7 4) 2 . 0 3 (0 . 0 8 0) 7.6 2 (0 .3 0) 0 .6 4 (0 . 025) 7.6 2 (0 .3 00) 2 .77 (0 .1 0 9 ) 1.8 5 (0 . 0 73 ) 0 .6 4 (0 . 025) d i a . 5 . 0 8 (0 . 200) 3.81 (0 .1 50) max . 3. 5 6 (0 .1 40) m i n . 2 . 0 3 (0 . 0 8 0) 10 . 1 6 (0 . 400) 5 . 0 8 (0 . 200) 6.86 (0 . 2 7 ) 1 8.8 0 (0 .7 40) 1 8. 2 9 (0 .7 20)
4 versatile link printed board layout dimensions horizontal module vertical module interlocked (stacked) assemblies (refer to figure 1) horizontal packages may be stacked by placing units with pins facing upward. initially engage the inter - locking mechanism by sliding the l bracket body from above into the l slot body of the lower package. use a straight edge, such as a ruler, to bring all stacked units into uniform alignment. this tech nique prevents potential harm that could occur to fingers and hands of assemblers from the package pins. stacked horizontal packages can be disengaged if necessary. repeated stacking and unstack ing causes no damage to individual units. to stack vertical packages, hold one unit in each hand, with the pins facing away and the optical ports on the bottom. slide the l bracket unit into the l slot unit. the straight edge used for horizontal package alignment is not needed. stacking horizontal modules figure 1 . interlocked (stacked) horizontal or vertical packages stacking vertical modules 4 1 3 2 5 8 7.6 2 (0 .3 00) 1. 0 1 (0 . 040) d i a . 1.8 5 (0 . 0 73 ) m i n . pcb edge t op v i e w 2 . 54 (0 .1 00) 7.6 2 (0 .3 00) d i mens i ons i n m i ll i me t ers ( i nc h es) .
