indibano PCByibhodi ethengisa amacandelo ahlukeneyo kumphezulu webhodi yesekethe eprintiweyo.Kunye nophuhliso lwenzululwazi nobuchwepheshe, abantu baye baqalisa ukunikela ingqalelo ngakumbi nangakumbi ixesha ukusetyenziswa kwebhodi yesekethe yendibano PCB kunye nokuthembeka ukusebenza high-frequency, kwaye ke indibano PCB kwakhona ngakumbi nangakumbi ingqalelo yayo. beka ubomi kwishelufa.Kwiimeko eziqhelekileyo, ixesha lokugcina indibano yePCB yi-2 ~ 10 iminyaka.
Iibhodi ezigqityiweyo zePCB ezichaphazela izinto zomjikelo wokugcina:
1. Imiba yokusingqongileyo
Imekobume efumileyo nothuli ngokucacileyo ayiluncedi ugcino lwendibano yePCB.Ezi zinto ziya kukhawulezisa i-oxidation kunye nokungcoliswa kwendibano ye-PCB kwaye ibenze bufutshane ubomi beshelufu.Ngokubanzi, kuyacetyiswa ukuba kugcinwe indibano yePCB kwindawo eyomileyo, engenathuli neqondo lobushushu elingaguqukiyo elingama-25°C.
2. Ukuthembeka kwamacandelo
Ukuthembeka kwamacandelo kwii-PCBA ezahlukeneyo kwakhona kumisela ubomi beshelufu yendibano ye-PCB kumlinganiselo omkhulu.Izixhobo ezisebenzisa izinto ezikumgangatho ophezulu kunye neenkqubo zinamandla okumelana neendawo ezinzima.Inoluhlu olubanzi lwezakhono kunye nokumelana ne-oxidation enamandla.Ikwabonelela ngesiqinisekiso sozinzo lwendibano yePCB.
3. Izinto eziphathekayo kunye neteknoloji yonyango ye-PCB
Ibhodi yesekethe eprintiweyoizinto eziphathekayo azichatshazelwa lula ngokusingqongileyo, kodwa inkqubo yabo yonyango yomhlaba ichaphazeleka kakhulu yi-oxidation yomoya.Unyango olulungileyo lomphezulu lunokwandisa ubomi beshelufu yendibano yePCB.
4. PCBA ibhodi eqhuba umthwalo
Umthwalo wendibano yePCB yeyona nto ibalulekileyo ebomini bayo.I-frequency ephezulu kunye nokusebenza komthwalo ophezulu kuya kuvelisa impembelelo ephezulu eqhubekayo kwimigca kunye namacandelo ebhodi yesekethe, ekulula ukuyi-oxidize phantsi kweempembelelo zokufudumeza, okubangelwa isiphaluka esifutshane kunye nesekhethi evulekileyo ngexesha lokusebenza kwexesha elide.Ngoko ke, iiparamitha zokusebenza zebhodi yendibano yePCB kufuneka zibe phakathi koluhlu oluphakathi lwamacandelo ukuphepha ukusondela kwixabiso eliphezulu, ukuze kukhuseleke ngokufanelekileyo indibano yePCB kunye nokwandisa ubomi bayo bokugcina.
Sinentembelo ekuboneleleni ngeyona ndibaniselwano ilungileyoInkonzo yokuhlanganisa iqhosha le-PCB, umgangatho, ixabiso kunye nexesha lonikezelo kwi-batch yakho encinci yevolumu ye-PCB i-odolo yendibano kunye ne-Mid batch Volume PCB i-oda yendibano.
