Ngaba isiphelo esicinezelwe ngokubandayo sifumene ukothuka okushushu kakhulu ngexesha lonyango lobushushu?
Izinto Ezibangela Uloyiko Oluphezulu Lobushushu
Ukothuka kobushushu obuphezulu kubonakala kakhulu njengokunyuka ngokukhawuleza kobushushu bomzimba osisigxina kwixesha elifutshane, okukhokelela kuthotho lotshintsho lomzimba. Izizathu eziphambili kunye neempawu zezi zilandelayo:
Iimeko zeNkqubo eziqhelekileyo: Iingxaki zihlala zenzeka ngexesha leenkqubo zokuhlanganisa ibhodi ye-PCB, ezinje ngokugalela ngamaza kunye nokugalela ngokutsha. Kwigalela ngamaza, amaqondo obushushu okufudumeza kwangaphambili anokufikelela ngaphezulu kwe-100°C, kwaye amaqondo obushushu aphezulu amaza anokufikelela nakwi-280°C okomzuzwana; kwindawo yokufudumeza kwangaphambili yokugalela ngokutsha, amaqondo obushushu aphezulu anokudlula kwi-230°C.
Iimpawu Ezithe Ngqo: Amaqondo obushushu aphezulu ngequbuliso anokubangela ukuba iindawo zokukhusela zeplastiki zesiphelo zinyibilike, zijijeke, zibe namaqamza, okanye ziguquguquke, kwaye iindawo zesinyithi nazo zinokutshintsha iimpawu ngenxa yobushushu obuphezulu.
Iingozi Eziphambili Ezibangelwa Kukukhwankqiswa Kobushushu Obuphezulu
Umothuko oshushu kakhulu awuchaphazeli nje kuphela iiterminals ngokwazo, kodwa unokubangela uthotho lweengxaki zokuthembeka nokhuseleko:
Ukwanda Kokumelana Noqhagamshelwano Okukhokelela Kwimijikelo Yokushushu Kakhulu: Amaqondo obushushu aphezulu anokubangela i-oxidation kwiindawo zoqhagamshelwano zeeterminals kunye nee-conductors, okwenza iileya ezincinci ze-oxide. Oku kunokunyusa kakhulu ukumelana noqhagamshelwano, kwaye ukumelana okwandileyo kuvelisa ubushushu obongezelelekileyo, okwenza umjikelo ombi, onokuthi kwiimeko ezinzima ubangele nomlilo.
Amandla Oomatshini Anciphileyo: Amaqondo obushushu aphezulu anokutsala izinto ezithambileyo ngaphakathi kwesiphelo, nto leyo ebangela ukuba zilahlekelwe bubuthambile kwaye zinciphise uxinzelelo loqhagamshelwano, nto leyo ekhokelela ekuqhagamshelweni okukhululekileyo. Kwangaxeshanye, umaleko wobushushu weentambo unokuguga kwaye ube buthaka phantsi kwamaqondo obushushu aphezulu, nto leyo enciphisa ukusebenza kobushushu.
Impembelelo kuMthamo woKuthwala uMbane: Ukuba indawo yokugoba ayilwanga okanye ayilungiswanga kakuhle (umz., umlinganiselo wokucinezelwa ongalunganga), indawo yayo enqamlezileyo inokuncipha, nto leyo ekhokelela ekubeni umthamo wokuthwala umbane unganeli kwaye kube lula ukuvelisa ubushushu xa umbane uhamba.
Indlela Yokuphendula Nokusombulula Ukothuka Okuphezulu Kobushushu
Lungiselela uKhetho lwezinto: Khetha iintsimbi ezinokumelana nobushushu obuphezulu (ezifana nobhedu oluqhuba kakuhle) kunye nezinto zeresin.
Phucula Inkqubo Yokugoba: Lawula ngokungqongqo umlinganiselo wokugoba (umlinganiselo wokugoba wesiphelo ocetyiswayo yi-65%–75%, umlinganiselo wokugoba we-conductor yi-65%–80%).
Lawula ngokuchanekileyo Inkqubo Yonyango Lobushushu: Lawula ngokuchanekileyo ubushushu kunye nexesha kwindawo yokufudumeza kwangaphambili, indawo yamaza, kunye nendawo ephakamileyo ukuze uphephe ukuvezwa okungeyomfuneko kobushushu obuphezulu ixesha elide. Landela ngokungqongqo ifestile yenkqubo ukuze uthintele ukothuka okubangelwa kukuphambuka kwenkqubo.
Qinisa uLawulo lweNkqubo yoQhagamshelo: Qinisekisa ukuba iphini ye-solder ibekwe ngokuchanekileyo kwaye inobungakanani obufanelekileyo; qinisekisa ukuba ii-terminals ziyanyibilika; emva kokuhlanganiswa, hlamba kakuhle ngaphandle kokukhupha intsalela ye-flux. Susa impembelelo embi yezinto zangaphandle kwii-terminals.
I-Adopt Alternative Connection Technologies: Kwiimveliso ezineemfuno eziphezulu zamandla ombane kunye nokunyuka kwamaqondo obushushu okungqongqo, cinga ngokusebenzisa i-high-frequency welding kunye nezinye iindlela zokudibanisa. I-high-frequency welding ivumela i-copper ukuba idibane kwinqanaba le-molecular, nto leyo ekhokelela ekuchaseni okuphantsi kunye nolawulo olungcono lokunyuka kwamaqondo obushushu.
