Inductor Bonding
Kwiminyaka yakutshanje, imfuno yokunciphisa ubungakanani beemveliso ezidityanisiweyo ikhokelele ekuncipheni okukhulu kubungakanani bamalungu emveliso ye-inductor ngokunjalo, oku kuzisa imfuneko yetekhnoloji yokunyusela ephucukileyo yokufaka ezi ndawo zincinci kwiibhodi zabo zesekethe.
Iinjineli ziye zavelisa i-solder paste, izinto zokuncamathelisa, kunye neenkqubo zokuhlanganisa ezivumela ukuncamathisela iitheminali ze-inductor kwiiPCB ngaphandle kokusebenzisa imingxunya. Iindawo ezithe tyaba (ezaziwa ngokuba ziipads) kwiitheminali ze-inductor zithengiswa ngokuthe ngqo kwimiphezulu ye-copper circuitry surfaces kungoko igama elithi i-surface inductor (okanye i-transformer). Le nkqubo iphelisa imfuneko yokugrumba imingxuma yezikhonkwane, ngaloo ndlela inciphisa iindleko zokwenza iPCB.
I-adhesive bonding (i-gluing) yindlela eqhelekileyo yokudibanisa i-concentrators kwi-coil induction. Umsebenzisi kufuneka aqonde ngokucacileyo iinjongo zokudibanisa: nokuba kukugcina kuphela isilawuli kwikhoyili okanye ukubonelela ngokupholisa kwayo okunzulu ngokugqithiswa kobushushu kwikhoyili epholileyo yamanzi.
Uqhagamshelo lomatshini yeyona ndlela ichanekileyo kwaye inokwethenjelwa yokunamathisela abalawuli kwiikhoyili ze-induction. Inokumelana nokunyakaza kwe-thermal kunye nokungcangcazela kwamacandelo ekhoyili ngexesha lenkonzo.
Kukho iimeko ezininzi xa abalawuli benokuthi baqhotyoshelwe kungekhona kwikhoyili ejikayo, kodwa kumacandelo esakhiwo sofakelo lwe-induction ezifana neendonga zegumbi, iifreyimu zezikhuselo zamagnetic, njl.
Indlela yokufaka i-inductor ye-radial?
I-toroids inokudityaniswa kwintaba kunye nokuba ne-adhesives okanye iindlela zoomatshini. Ukunyuswa kwe-toroid okumilise indebe kunokuzaliswa ngembiza okanye i-encapsulation ikhompawundi ukubambelela kunye nokukhusela inxeba le-toroid. Ukunyuka okuthe tyaba kunika iprofayile ephantsi kunye neziko eliphantsi lomxhuzulane kwizicelo eziya kufumana ukothuka kunye nokungcangcazela. Njengoko i-diameter ye-toroid isiya iba nkulu, ukunyuswa okuthe tyaba kuqalisa ukusebenzisa ibhodi yesekethe exabisekileyo yezindlu. Ukuba kukho indawo kwindawo ebiyelweyo, ukunyuswa ngokuthe nkqo kusetyenziswa ukugcina indawo yebhodi.
Izikhokelo ezivela kwi-toroidal winding zifakwe kwii-terminals zentaba, ngokuqhelekileyo ngokuthengiswa. Ukuba ucingo lokujija lukhulu kwaye luqinile ngokwaneleyo, ucingo lunokuthi "luzikhokele ngokwalo" kwaye lubekwe ngentloko okanye lufakwe kwibhodi yesekethe eprintiweyo. I-advanteji yokukhwela i-self ekhokelayo kukuba iindleko kunye nokuba sesichengeni soqhagamshelwano olongezelelweyo lwe-solder oluphakathi luyaphetshwa. I-toroids inokudityaniswa kwintaba kunye nokuba ne-adhesives, iindlela zoomatshini okanye nge-encapsulation. Ukunyuswa kwe-toroid okumilise indebe kunokuzaliswa ngembiza okanye i-encapsulation ikhompawundi ukubambelela kunye nokukhusela inxeba le-toroid. Ukunyuswa ngokuthe nkqo kusindisa umhlaba webhodi yesekethe xa ubukhulu be-toroid buba bukhulu, kodwa kudala umba wobude becandelo. Ukunyuka ngokuthe nkqo kukwaphakamisa iziko lecandelo lomxhuzulane lilenze libe sesichengeni kukothuka kunye nokungcangcazela.
I-Adhesive Bonding
I-adhesive bonding (i-gluing) yindlela eqhelekileyo yokudibanisa i-concentrators kwi-coil induction. Umsebenzisi kufuneka aqonde ngokucacileyo iinjongo zokudibanisa: nokuba kukugcina kuphela isilawuli kwikhoyili okanye ukubonelela ngokupholisa kwayo okunzulu ngokugqithiswa kobushushu kwikhoyili epholileyo yamanzi.
Imeko yesibini ibaluleke kakhulu kwiikhoyili ezilayishwe kakhulu kunye nomjikelo wokufudumeza omde njengakwizicelo zokuskena. Eli tyala lifuna kakhulu kwaye liza kuchazwa ngakumbi. Izinto zokuncamathelisa ezahlukeneyo zingasetyenziselwa ukuncamathelisa ngeereyini ze-epoxy zizezona zisetyenziswa ngokuqhelekileyo iglu.
I-DeepMaterial adhesive kufuneka ibe nezi mpawu zilandelayo:
· Amandla ancamathelayo aphezulu
· Ukuqhuba kakuhle kwe-thermal
· Ukumelana nokushisa okuphezulu xa indawo edibeneyo kulindeleke ukuba ishushu. Gcina ukhumbule ukuba kwizicelo zamandla aphezulu ezinye iindawo zomphezulu wobhedu zinokufikelela kwi-200 C okanye nangaphezulu naphezu kokupholisa okunzulu kwamanzi kwikhoyili.
