Ubeko olufanelekileyo lwamacandelo e-elektroniki kwibhodi yePCB likhonkco elibaluleke kakhulu lokunciphisa iziphene zokuwelda!Amacandelo kufuneka aphephe iindawo ezinexabiso elikhulu kakhulu lokuphambuka kunye nemimandla ephezulu yoxinzelelo lwangaphakathi kangangoko kunokwenzeka, kwaye uyilo kufuneka lulingane kangangoko.
Ukuze ukwandise ukusetyenziswa kwendawo yebhodi yesekethe, ndiyakholelwa ukuba amaqabane amaninzi oyilo aya kuzama ukubeka amacandelo ngokuchasene nomphetho webhodi, kodwa enyanisweni, lo mkhuba uya kuzisa ubunzima obukhulu kwimveliso kunye nendibano yePCBA, kwaye nokuba ikhokele. ukungakwazi ukuwelda indibano oh!
Namhlanje, makhe sithethe ngokucwangciswa kwesixhobo somphetho ngokweenkcukacha
Ingozi yoyilo lwesixhobo secala lephaneli
01. Ibhodi yokubumba edge yokusila ibhodi
Xa amacandelo abekwe kufutshane kakhulu kumda weplate, i-welding pad yamacandelo iya kuchithwa xa i-plate yokugaya yenziwe.Ngokuqhelekileyo, umgama phakathi kwe-welding pad kunye nomda kufuneka ube mkhulu kune-0.2mm, ngaphandle koko i-welding pad ye-edge device iya kuchithwa kwaye indibano yangasemva ayikwazi ukuthunga amacandelo.
02. Ukwenza iplate edge V-CUT
Ukuba umphetho weplate nguMoses V-CUT, amacandelo kufuneka abe kude kumda weplate, kuba imela ye-V-CUT evela phakathi kweplate ingaphezulu kwe-0.4mm ukusuka kumda weplate. i-V-CUT, ngaphandle koko i-V-CUT imela iya kulimaza i-welding plate, okubangela ukuba amacandelo angenako ukuxutywa.
03. Izixhobo zokuphazamiseka kwecandelo
Ukucwangciswa kwamacandelo asondele kakhulu kumda wepleyiti ngexesha loyilo kunokuphazamisa ukusebenza kwezixhobo zokuhlanganisa ngokuzenzekelayo, ezifana ne-wave-soldering okanye i-reflow welding machines, xa kuhlanganiswa amacandelo.
04. Isixhobo siyantlitheka kumalungu
Inxalenye esondeleyo kumda webhodi, inkulu amandla ayo okuphazamisa isixhobo esidibeneyo.Ngokomzekelo, amacandelo afana ne-electrolytic capacitors enkulu, emide, kufuneka abekwe kude kumda webhodi kunamanye amacandelo.
05. Amalungu ebhodi engaphantsi awonakele
Emva kokuba indibano yemveliso igqityiwe, imveliso eqingqiweyo kufuneka ihlulwe kwi-plate.Ngexesha lokwahlula, amacandelo asondele kakhulu kumda angonakaliswa, anokuthi abe phakathi kwaye kube nzima ukuzibona kunye nokucima.
Oku kulandelayo kukwabelana ngemeko yemveliso malunga nomgama wesixhobo somda awonelanga, kukhokelela kumonakalo kuwe ~
Inkcazo yengxaki
Kufunyenwe ukuba isibane se-LED semveliso sisondele kumda webhodi xa i-SMT ibekwe, ekulula ukubethelwa kwimveliso.
Impembelelo yengxaki
Ukuveliswa kunye nokuthutha, kunye nesibane se-LED siya kuphulwa xa inkqubo ye-DIP idlula umzila, oya kuchaphazela umsebenzi wemveliso.
Ukwandiswa kwengxaki
Kuyimfuneko ukutshintsha ibhodi kwaye uhambise i-LED ngaphakathi kwebhodi.Ngexesha elifanayo, kuya kubandakanya utshintsho lwekholamu yesikhokelo sokukhanya kwesakhiwo, okubangela ukulibaziseka okukhulu kumjikelezo wophuhliso lweprojekthi.
Ukufunyanwa komngcipheko wezixhobo ezinqamlekileyo
Ukubaluleka koyilo loyilo lwecandelo kuyabonakala, ukukhanya kuya kuchaphazela i-welding, enzima iya kukhokelela ngokuthe ngqo kumonakalo wesixhobo, ngoko ke uqinisekisa njani ukuba iingxaki zoyilo eziyi-0, kwaye emva koko ugqibezele ngempumelelo imveliso?
Ngomsebenzi wokuhlanganisa kunye nokuhlalutya, I-BEST inokuchaza imigaqo yokuhlola ngokweeparamitha zomgama ukusuka kumda wodidi lwecandelo.Kwakhona inezinto zokuhlola ezikhethekileyo zokwakheka kwamacandelo ecala leplate, kubandakanywa izinto ezininzi zokuhlola ezineenkcukacha ezifana nesixhobo esiphezulu ukuya kumda weplate, isixhobo esisezantsi ukuya kumda wepleyiti, kunye nesixhobo somgaqo kaloliwe. umda womatshini, onokuhlangabezana ngokupheleleyo neemfuno zoyilo lovavanyo olukhuselekileyo lomgama wesixhobo ukusuka kumda weplate.
