Kubikwa ukuba itekhnoloji ye-laser (iinkqubo ezingaphezu kwama-20 ezahlukeneyo) kunye nezixhobo zokuvelisa ezinxulumene noko zisetyenziswa malunga nama-70% eekhonkco zokucubungula imveliso ye-elektroniki kunye nokuvelisa.
Okwangoku, ukuwelda indawo echanekileyo nge-laser kusetyenziswa kakhulu kwiikhabhathi zemveliso ze-elektroniki, izigqubuthelo zokukhusela, izihlanganisi ze-USB, ii-conductive patches, njl. Inezibonelelo ezinje ngokuguquguquka kobushushu obuncinci, ulawulo oluchanekileyo lwendawo yesenzo kunye nendawo, umgangatho ophezulu wokuwelda, ukukwazi ukufikelela ekuwelding kwezinto ezahlukeneyo, kunye nokuzisebenzela ngokulula. Nangona kunjalo, iindlela ezahlukeneyo zokuwelda kufuneka zisetyenziswe xa kuwelda izixhobo ezahlukeneyo.
Ngokusekelwe kwiziphumo zovavanyo oluninzi, iinjineli zokudibanisa iintsimbi zishwankathele eyona ndlela ifanelekileyoukuwelda indawo echanekileyo nge-laseriindlela zezinto ezahlukeneyo ezifana nezinto ezikhanyayo kakhulu, amaphepha esinyithi abhityileyo, kunye nezinto ezahlukeneyo kwimveliso nakwimveliso yezinto ze-elektroniki zabathengi.
1. Indlela yokuWelda yeLaser Precision Spot yeZixhobo eziKhazimlayo kakhulu
Xa kudityaniswa izinto ezikhanyayo kakhulu ezifana ne-aluminium kunye nobhedu, ii-waveforms ezahlukeneyo ze-welding zinempembelelo enkulu kumgangatho we-welding. Ukusebenzisa i-laser waveform ene-pre-spike kunokugqobhoza umqobo wokubonakalisa ophezulu. Amandla aphezulu akhawulezileyo anokutshintsha ngokukhawuleza imeko yomphezulu wesinyithi, anyuse ubushushu bawo aye kwinqanaba lokunyibilika, ngaloo ndlela anciphise ukubonakaliswa komphezulu wesinyithi kwaye aphucule ukusetyenziswa kwamandla. Ukongeza, ngenxa yokuqhuba ngokukhawuleza kobushushu bezinto ezifana nobhedu kunye ne-aluminium, ukusetyenziswa kwe-waveform ebola kancinci kunokuphucula ukubonakala kwamabala e-weld.
Kwelinye icala, izinga lokufunxwa kwelaser kwezinto ezifana negolide, isilivere, ubhedu, kunye nentsimbi liyancipha njengoko ubude bomda busanda. Kwikopolo, xa ubude bomda belaser buyi-532nm, izinga lokufunxwa kobhedu lisondele kwi-40%. Uhlalutyo oluthelekisayo lweempawu ze-infrared lasers kunye ne-green lasers lubonisa ukuba ii-infrared lasers zinobukhulu obukhulu bebala, ubunzulu obufutshane be-focal, kunye nezinga eliphantsi lokufunxwa yi-red copper; ii-green lasers zinobukhulu obuncinci bebala, ubunzulu obude be-focal, kunye nezinga eliphezulu lokufunxwa yi-red copper. Xa i-pulse spot welding yenziwa kwi-red copper kusetyenziswa ii-infrared lasers kunye ne-green lasers ngokulandelanayo, kufunyaniswa ukuba ubukhulu be-iindawo zokuwelda emva kokuweldange-infrared lasers akuhambisani, ngelixa amabala okuwelda enziwe yi-green lasers afanayo ngobukhulu, ahambelana ngobunzulu, kwaye agudileyo kumphezulu (Imifanekiso 1-2). Ukuwelda nge-green lasers kufezekisa iziphumo ezizinzileyo, kwaye amandla aphezulu afunekayo angaphantsi kwesiqingatha kune-infrared lasers.
