Intshayelelo.
Inkqubo yokuhlaziya isoloko ingahoywa ziifektri ezininzi, ukanti ezona ntsilelo zingenakuthintelwa zenza ukuba kusetyenzwe kwakhona kubalulekile kwinkqubo yendibano.Ngoko ke, inkqubo yokuphinda iphinde icoceke iyinxalenye ebalulekileyo yenkqubo yokuhlanganisana engacocekanga.Eli nqaku lichaza ukukhethwa kwezinto ezifunekayo kwinkqubo yokusebenza kwakhona engacocekanga, uvavanyo kunye neendlela zenkqubo.
I. Akukho-clean rework kunye nokusetyenziswa kokucoca CFC phakathi umahluko
Kungakhathaliseki ukuba luhlobo luni lokuphinda lusebenze injongo yalo iyafana - kwindibano yesiphaluka eprintiweyo ekususweni okungonakalisi kunye nokubekwa kwamacandelo, ngaphandle kokuchaphazela ukusebenza kunye nokuthembeka kwamacandelo.Kodwa inkqubo ethile yokuphinda icoceke usebenzisa i-CFC yokucoca kwakhona iyahluka kuba iyahluka.
1. ekusebenziseni i-CFC yokucoca i-rework rework, amacandelo ahlaziywe ngokutsha ukudlula inkqubo yokucoca, inkqubo yokucoca ngokuqhelekileyo ifana nenkqubo yokucoca esetyenziselwa ukucoca isiphaluka esiprintiweyo emva kwendibano.Ukucoca-free rework ayikho le nkqubo yokucoca.
2. ekusetyenzisweni kweCFC yokucoca ngokutsha, ukusebenza ukuze kuphunyezwe amalungu amahle e-solder kuwo wonke amacandelo aphinde asebenze kunye nommandla webhodi yesekethe eprintiweyo kufuneka usebenzise i-solder flux ukususa i-oxide okanye enye ungcoliseko, ngelixa kungekho ezinye iinkqubo zokuthintela ukungcoliseka kwimithombo efana igrisi yomnwe okanye ityuwa, njl.njlUkungahlambuluki kwakhona, ngakolunye uhlangothi, kubeka yonke into kwindibano yesiphaluka eprintiweyo, okubangela uluhlu lweengxaki ezifana nokuthembeka kwexesha elide lamalungu e-solder, ukuhambelana kwakhona, ukungcoliswa kunye neemfuno zomgangatho wezithambiso.
Njengoko kungekho-clean rework ayibonakali inkqubo yokucoca, ukuthembeka kwexesha elide lamalungu e-solder kunokuqinisekiswa kuphela ngokukhetha izinto ezifanelekileyo zokulungisa kunye nokusebenzisa ubuchule obufanelekileyo bokuthengisa.Kwi-rework engacocekanga, i-solder flux kufuneka ibe yintsha kwaye ngexesha elifanayo isebenze ngokwaneleyo ukususa i-oxides kunye nokufezekisa ukumanzisa okulungileyo;intsalela yendibano yesiphaluka eprintiweyo ifanele ingathathi cala yaye ingachaphazeli ukuthembeka kwexesha elide;ukongezelela, intsalela yendibano yesiphaluka eshicilelweyo ifanele ihambelane nombandela wokuphinda wenziwe yaye intsalela entsha eyilwe ngokudityaniswa enye nenye imele ingabi ngoondilele.Ngokuqhelekileyo ukuvuza phakathi kwee-conductor, i-oxidation, i-electromigration kunye nokukhula kwe-dendrite kubangelwa ukungahambelani kwezinto kunye nokungcoliswa.
Umgangatho wembonakalo yemveliso yanamhlanje ngumba obalulekileyo, njengoko abasebenzisi bajwayele ukukhetha iindibano zesekethe ezicocekileyo nezicwebezelayo eziprintiweyo, kwaye ubukho balo naluphi na uhlobo lwentsalela ebonakalayo ebhodini kuthathwa njengokungcoliseka kunye nokugatywa.Nangona kunjalo, i-residus ebonakalayo ihambelana nenkqubo yokuphinda ihlambuluke kwaye ayimkelekanga, nangona zonke ii-residus ezivela kwi-rework process zingathathi hlangothi kwaye azichaphazeli ukuthembeka kwendibano yesiphaluka eprintiweyo.
Ukusombulula ezi ngxaki kukho iindlela ezimbini: enye kukukhetha izinto echanekileyo rework, yayo hayi-ecocekileyo rework emva komgangatho solder joint emva kokucoca kunye CFC elungileyo njengoko umgangatho;okwesibini kukuphucula iindlela zangoku zokuphinda usebenze ngesandla kunye neenkqubo zokuphumeza ukuthengisela okuthembekileyo okungacocekanga.
II.Ukuphinda ukhethe izinto eziphathekayo kunye nokuhambelana
Ngenxa yokuhambelana kwezinto, inkqubo yendibano engacocekanga kunye nenkqubo yokuphinda iphinde isebenze idityanisiwe kwaye ixhomekeke kwelinye.Ukuba izinto eziphathekayo azikhethwanga ngokuchanekileyo oku kuya kukhokelela ekusebenzisaneni okuya kunciphisa ubomi bemveliso.Uvavanyo lokuhambelana luhlala lucaphukisa, lubiza kwaye luthatha ixesha.Oku kungenxa yenani elikhulu lezinto ezibandakanyekayo, izinyibilikisi zovavanyo ezibizayo kunye neendlela ezinde zovavanyo eziqhubekayo njl njl. Izinto ezibandakanyekayo ngokubanzi kwinkqubo yokuhlanganisa zisetyenziswa kwiindawo ezinkulu, kubandakanya intlama ye-solder, i-solder yamaza, i-adhesives kunye ne-form-fitting coatings.Inkqubo yokuvuselela, ngakolunye uhlangothi, idinga izinto ezongezelelweyo ezifana ne-rework solder kunye ne-solder wire.Zonke ezi zixhobo kufuneka zihambelane nazo naziphi na izicoci okanye ezinye iintlobo zokucoca ezisetyenziswe emva kokushicilela ibhodi yesekethe eprintiweyo kunye ne-solder paste ephosakeleyo.
