CLEANING
Ingeneral,cleaningthepopulatedmodulesis
stronglydiscouraged.Residualsunderthemodule
cannotbeeasilyremovedwithanycleaning
process.
 Cleaningwithwatercanleadtocapillaryeffects
wherewaterisabsorbedintothegapbetween
thehostboardandthemodule.The
combinationofsolderingfluxresidualsand
encapsulatedwatercouldleadtoshortcircuits
betweenneighboringpads.Watercouldalso
damageanystickersorlabels.
 Cleaningwithalcoholorasimilarorganic
solventwilllikelyfloodsolderingfluxresiduals
intotheRFshield,whichisnotaccessiblefor
post‐washinginspection.Thesolventcouldalso
damageanystickersorlabels.
 Ultrasoniccleaningcoulddamagethemodule
permanently.
OPTICALINSPECTION
AftersolderingtheModuletothehostboard,
consideropticalinspectiontocheckthefollowing:
 Properalignmentandcenteringofthemodule
overthepads.
 Propersolderjointsonallpads.
 Excessivesolderorcontactstoneighboring
pads,orvias.
REWORK
Themodulecanbeunsolderedfromthehostboard
iftheMoistureSensitivityLevel(MSL)requirements
aremetasdescribedinthisdatasheet.
Never attempt a rework on the module
itself,e.g.replacingindividualcomponents.
Suchactionswillterminatewarranty
coverage.
SHIPPING,HANDLING,ANDSTORAGE
Shipping
BulkordersoftheTiWi5modulesaredeliveredin
traysof100orreelsof1,000.
Handling
TheTiWi5modulescontainahighlysensitive
electroniccircuitry.HandlingwithoutproperESD
protectionmaydestroyordamagethemodule
permanently.
MoistureSensitivityLevel(MSL)
