Iimpawu zebhodi yesekethe emacaleni kabini
Ibhodi yesiphaluka esinecala elinye kunye nebhodi yesiphaluka esinamacala amabini kumahluko inani leemaleko zobhedu zihluke.Ibhodi yesekethe enamacala amabini yibhodi kumacala omabini obhedu, ingaba ngomngxuma wokudlala indima yokudibanisa.Icala elinye kuphela umaleko wobhedu, unokwenza kuphela umgca olula, umngxuma owenziweyo ungasetyenziselwa kuphela iplagi-in ayikwazi ukuqhuba.
Iimfuno zobugcisa zebhodi yesekethe emacaleni kabini ukuxinana kweengcingo uba mkhulu, umngxuma omncinane ububanzi, metalized umngxuma umngxuma ububanzi nayo iya incinci.I-Layer kunye ne-layer interconnection ixhomekeke kwi-metallization hole, umgangatho uhambelana ngokuthe ngqo nokuthembeka kwebhodi yesekethe eprintiweyo.
Ngokucuthwa kwe-aperture, i-original kwi-aperture enkulu ayizange ichaphazele i-debris, njenge-debris yokusila, uthuthu lwe-volcanic, xa lusele luhlala kumngxuma omncinci ngaphakathi, luya kwenza i-chemical precipitation copper, i-copper plating ilahlekelwe yimpembelelo, umngxuma. ngaphandle kobhedu, ibe yintsimbi yomngxuma yombulali obulalayo.
Indlela yokuwelda ibhodi yesekethe emacaleni kabini
Ibhodi yesekethe enamacala amabini ukuze kuqinisekiswe ukuba isekethe enamacala amabini inefuthe elithembekileyo lokuqhuba, sicebisa ukuba uqale usebenzise iingcingo kwaye udibanise umngxuma woqhagamshelo kwiphaneli enamacala amabini (okt, inkqubo yesinyithi ngokusebenzisa umngxuma inxalenye), kwaye unqumle incam yomgca woqhagamshelo ephumayo inxalenye, ukuze ungahlaba isandla somqhubi, nto leyo ibhodi umsebenzi wokulungiselela uqhagamshelo.
Izinto eziyimfuneko zebhodi yesekethe emacala mabini
1. Kukho iimfuno zokubunjwa kwesixhobo kufuneka zihambelane neemfuno zenkqubo yemizobo yenkqubo;oko kukuthi, ukubunjwa kuqala emva kweplagi-in.
2. emva kokubumba imodeli yecala le-diode kufuneka ijonge phezulu, akufanele kubekho ukungahambisani nobude bezikhonkwane ezimbini.
3. isixhobo esineemfuno ze-polarity xa sifakwe ukunika ingqalelo kwi-polarity yayo asiyi kufakwa kwi-reverse, i-roll edibeneyo yebhloko, emva kokufaka, nokuba isixhobo sithe nkqo okanye silele, akuyi kubakho ukuthambeka okucacileyo.
4. Amandla entsimbi ye-soldering ye-25 ukuya kwi-40W, ubushushu bentloko yentsimbi kufuneka ilawulwe malunga ne-242 ℃, iqondo lobushushu liphezulu kakhulu entloko ngokulula "lifile", iqondo lobushushu liphantsi alikwazi ukunyibilikisa i-solder, ulawulo lwexesha le-solder kwi-3 ukuya kwi-4. imizuzwana.
5.Hlaziya i-oveni or umatshini wokuthambisa wamazaukuwelda okusesikweni ngokubanzi ngokungqinelana nesixhobo ukusuka mfutshane ukuya phezulu, ukusuka ngaphakathi ukuya ngaphandle umgaqo welding ukusebenza, ixesha welding ukuya inkosi, ixesha elide kakhulu uya kutshisa isixhobo, uya kutshisa imigca enxitywe ubhedu phezu kwengubo yobhedu. ibhodi.
6. Ngenxa yokuba i-welding ephindwe kabini, ngoko kufuneka yenze inkqubo yokubeka isakhelo sebhodi yesekethe njalo njalo, injongo ayiyikucinezela i-oblique phantsi kwesixhobo.
7. emva kokugqitywa ibhodi yesekethe soldering kufuneka itsheki olubanzi kwinani uhlobo, khangela indawo apho kukho ukuvuza ukufakwa kunye ukuvuza welding, ukuqinisekisa izixhobo ibhodi yesekethe ezingafunekiyo ezifana pin ukucheba, emva kokuba ephumela kwinkqubo elandelayo.
I-8, ekusebenzeni okuthe ngqo, kufuneka kwakhona ilandele ngokungqongqo imigangatho yenkqubo efanelekileyo yokusebenza ukuqinisekisa umgangatho we-welding yemveliso.
Ngophuhliso olukhawulezayo lobuchwepheshe obuphezulu, kunye nobudlelwane obusondeleyo boluntu kunye neemveliso ze-elektroniki kuhlaziyo oluqhubekayo, uluntu lufuna ukusebenza okuphezulu, ubungakanani obuncinci, iimveliso ze-elektroniki ezisebenzayo ezininzi, ezibeka phambili iimfuno ezintsha zebhodi yesekethe.
Ibhodi yesekethe enamacala amabini ke ngoko yazalwa, ngenxa yokusetyenziswa ngokubanzi kwebhodi yesekethe enamacala amabini, ibangela ukuba ibhodi yesekethe eprintiweyo ivelise ukukhanya, okuncinci, okufutshane, uphuhliso oluncinci.
