Selective Soldering Recommendations
Selectivedipsolderingisavariationofreowsoldering.Inthismethod,theprintedcircuitboardwiththrough-hole
componentstobesolderedispreheatedandtransportedoverthesolderbathasinnormalowsolderingwithouttouching
thesolder.Whentheboardisoverthebath,itisstoppedandpre-designedsolderpotsareliftedfromthebathwithmolten
solderonlyattheplacesoftheselectedcomponents,andpressedagainstthelowersurfaceoftheboardtosolderthe
components.
Thetemperatureproleforselectivesolderingissimilartothedoublewaveowsolderingoutlinedinthisdocument,
however, instead of two baths, there is only one bath with a time from 3 to 10 seconds. In selective soldering, the risk of
overheatingisgreaterthanindoublewaveowsoldering,andgreatcaremustbetakensothatthepartsarenotoverheated.
