Umahluko phakathi kweebhodi zeesekethe zecala elinye kunye neebhodi zeesekethe eziphindwe kabini linani leengqimba zobhedu.Isayensi edumileyo: iibhodi zesekethe ezinamacala amabini zinobhedu kumacala omabini ebhodi yesekethe, enokunxibelelana nge-vias.Nangona kunjalo, kukho uluhlu olulodwa kuphela lobhedu kwelinye icala, elingasetyenziselwa kuphela iisekethe ezilula, kwaye imingxuma eyenziweyo ingasetyenziselwa kuphela ukudibanisa iplagi.

Iimfuno zobugcisa kwiibhodi zeesekethe eziphindwe kabini kukuba ukuxinana kwe-wiring kuba nkulu, i-aperture incinci, kwaye i-aperture ye-metalized hole iba yincinci kwaye incinci.Umgangatho wemingxuma ene-metallised apho i-layer-to-layer interconnection ixhomekeke ngokuthe ngqo ekuthembekeni kwebhodi eprintiweyo.

Ngokucutheka kobukhulu bepore, inkunkuma engazange ichaphazele ubungakanani bepore enkulu, njengebrashi yebrashi kunye nothuthu lwentaba-mlilo, xa sele ishiywe kumngxunya omncinci iya kubangela ukuba i-electroless copper kunye ne-electroplating ilahlekelwe yimpembelelo yayo, kwaye kuya kubakho imingxunya. ngaphandle kobhedu kwaye ibe yimingxuma.Umbulali obulalayo we-metallization.

Indlela ye-welding yebhodi yesiphaluka esinamacala amabini

Ukuze kuqinisekiswe impembelelo ethembekileyo yokuqhuba ibhodi yesekethe emacaleni amabini, kuyacetyiswa ukuba udibanise imingxuma yokudibanisa kwibhodi ephindwe kabini kunye neengcingo okanye into efana nayo (oko kukuthi, inxalenye yenkqubo ye-metallization). kwaye unqumle inxalenye ephumayo yomgca wokudibanisa Ukulimala kwisandla somqhubi, oku kukulungiselela ukuthungwa kwebhodi.

Izinto ezibalulekileyo zokuwelda ibhodi yesekethe emacaleni amabini:
Kwizixhobo ezifuna ukubunjwa, kufuneka zicutshungulwe ngokuhambelana neemfuno zemizobo yenkqubo;oko kukuthi, kufuneka zibunjwe kuqala kunye neplagi-in
Emva kokubumba, imodeli yecala le-diode kufuneka ijonge phezulu, kwaye akufanele kubekho ukungafani kubude bezikhonkwane ezimbini.
Xa ufaka izixhobo ezineemfuno ze-polarity, nikela ingqalelo kwi-polarity yazo ukuba ingaguqulwa.Emva kokufaka, qengqeleka amacandelo ebhloko edibeneyo, kungakhathaliseki ukuba sisixhobo esithe nkqo okanye esithe tye, akufuneki kubekho ukuthambeka okucacileyo.
Amandla entsimbi esetyenziselwa ukudibanisa i-soldering phakathi kwe-25 ~ 40W.Ubushushu bencam yentsimbi yokuthambisa kufuneka ilawulwe malunga ne-242℃.Ukuba iqondo lokushisa liphezulu kakhulu, i-tip ilula "ukufa", kwaye i-solder ayikwazi ukuncibilika xa iqondo lokushisa liphantsi.Ixesha le-solder kufuneka lilawulwe ngaphakathi kwe-3 ~ 4 isibini.
I-welding esemthethweni ngokuqhelekileyo yenziwa ngokomgaqo we-welding wesixhobo ukusuka kwifutshane ukuya phezulu kunye nangaphakathi.Ixesha le-welding kufuneka liphathwe kakuhle.Ukuba ixesha lide kakhulu, isixhobo siya kutshiswa, kwaye umgca wobhedu kwibhodi yeentsimbi zobhedu uya kutshiswa.
Ngenxa yokuba i-soldering ephindwe kabini, isakhelo senkqubo okanye into enjalo yokubeka ibhodi yesiphaluka kufuneka yenziwe kwakhona, ukwenzela ukuba ungacinezeli amacandelo angaphantsi.
Emva kokuba ibhodi yesekethe ithengiswe, kufuneka kuqwalaselwe ukukhangela okupheleleyo ukuze kufumaneke apho kungekho khona ukufakwa kunye ne-soldering.Emva kokuqinisekiswa, nciphisa izikhonkwane zesixhobo ezingafunekiyo kunye nokunye okunjalo kwibhodi yesekethe, kwaye emva koko ungene kwinkqubo elandelayo.
Kumsebenzi othile, imigangatho yenkqubo efanelekileyo kufuneka ilandelwe ngokungqongqo ukuqinisekisa umgangatho we-welding wemveliso.

Ngophuhliso olukhawulezayo lobuchwepheshe obuphezulu, iimveliso ze-elektroniki ezinxulumene ngokusondeleyo noluntu zihlala zihlaziywa.Uluntu lufuna iimveliso ze-elektroniki kunye nokusebenza okuphezulu, ubungakanani obuncinci kunye nemisebenzi emininzi, ebeka phambili iimfuno ezintsha kwiibhodi zesekethe.Kungenxa yoko le nto kwazalwa ibhodi yesekethe enamacala amabini.Ngenxa yokusetyenziswa okubanzi kweebhodi zeesekethe eziphindwe kabini, ukuveliswa kweebhodi zeesekethe eziprintiweyo kuye kwaba lula, kuncinci, kufutshane kwaye kuncinci.
