Ijiko elilungileyo le-reflux kufuneka libe lijiko lobushushu elinokufezekisa ukuwelda okulungileyo kwamacandelo ahlukeneyo okunyuka komphezulu kwibhodi ye-PCB ukuze idityaniswe, kwaye ijoyinti ye-solder ayinayo inkangeleko entle kuphela kodwa inomgangatho olungileyo wangaphakathi.Ukuze kuphunyezwe i-curve elungileyo ye-reflow-free-reflow curve, kukho ubudlelwane obuthile kunye nazo zonke iinkqubo zokuvelisa i-lead-free reflow.Apha ngezantsi, i-Chengyuan Automation iya kuthetha malunga nezizathu ze-welding ebandayo ebandayo okanye ukumanzisa kweendawo ezingenalo i-lead-free reflow.
Kwinkqubo ye-lead-free reflow welding, kukho umahluko obalulekileyo phakathi kwe-luster ekhanyayo ye-lead-free reflow solder joints kunye nesenzeko esincinci esibangelwa ukunyibilika okungaphelelanga kwe-solder paste.Xa ibhodi eqatywe nge-solder paste idlula kwiziko lobushushu obuphezulu begesi, ukuba ubushushu obuphezulu be-solder paste ayinakufikelelwa okanye ixesha le-reflux alanele, umsebenzi we-flux awuyi kukhutshwa, kwaye i-oxides kunye ezinye izinto ezikumphezulu wephedi ye-solder kunye ne-pin yecandelo ayinakucocwa, okukhokelela ekumanziseni okungalunganga ngexesha le-lead-free reflow welding.
Imeko enzima ngakumbi kukuba ngenxa yobushushu obunganeleyo, ubushushu be-welding ye-solder paste kumphezulu webhodi yesekethe ayikwazi ukufikelela kwiqondo lobushushu elimele liphunyezwe kwi-solder yesinyithi kwi-solder paste ukuba itshintshe isigaba, ikhokelela kwinto yokuwelda ebandayo kwindawo yokuwelda engena-lead-free reflow.Okanye ngenxa yokuba iqondo lobushushu lingonelanga, ukuguquguquka okushiyekileyo ngaphakathi kwintlama ye-solder ayinakuguquguquka, kwaye ingena ngaphakathi kwijoyinti ye-solder xa ipholile, ikhokelela ekubengezeni okubuthuntu kwejoyinti ye-solder.Kwelinye icala, ngenxa yeepropati ezihlwempuzekileyo ze-solder paste ngokwayo, nokuba ezinye iimeko ezifanelekileyo zinokuhlangabezana neemfuno zejiko lobushushu le-lead-free reflow welding, iipropati zomatshini kunye nenkangeleko ye-solder joint emva kwe-welding ayikwazi ukuhlangabezana ne iimfuno zenkqubo welding.
