Amabhodi Esekethe Aphrintiwe Asemaceleni Akabili

Ibhodi le-PCB elinamacala amabili liwuhlobo olubaluleke kakhulu lwebhodi le-PCB emakethe yebhodi lesifunda. Kunamabhodi e-PCB anezinhlangothi ezimbili anesisekelo sensimbi, ibhodi lesekethe le-Hi-Tg le-foil elisindayo, amabhodi e-PCB ayisicaba futhi asonteka kabili emaceleni, amabhodi e-PCB anemvamisa ephezulu, amabhodi e-PCB axubile ane-dielectric anezinhlangothi ezimbili, njll. Ilungele uhla olubanzi lwezimboni zobuchwepheshe obuphezulu ezifana nezokuxhumana ngezingcingo, imikhiqizo yesayensi, imikhiqizo yesayensi, ukunikezwa kwamandla kagesi, izinsimbi zokulawula zezokwelapha. izimoto, i-aerospace defense, njll.

Inqubo yokuhlela

Amabhodi aphrintiwe kabili emaceleni ngokuvamile enziwa ngendwangu yengilazi ye-epoxy ye-copper foil. Isetshenziselwa ikakhulukazi ukuxhumana nge-elekthronikhi enezidingo zokusebenza okuphezulu Izinsiza, izinsimbi ezithuthukile namakhompyutha we-elekthronikhi, njll.

Inqubo yokukhiqiza yamabhodi anezinhlangothi ezimbili ngokuvamile ihlukaniswa ngezindlela eziningana, okuhlanganisa indlela yocingo lwenqubo, indlela yokuvimba imbobo, indlela yokufihla ubuso, kanye nendlela yokufaka i-electroplating eyingcaca.

Ukusampula

Indlela evame ukusetshenziswa kakhulu yesampula ye-PCB enezinhlangothi ezimbili yinqubo. Ngasikhathi sinye, inqubo ye-rosin, inqubo ye-OSP, inqubo yokunamathisela igolide, ukufakwa kwegolide, kanye nezinqubo zokucwecwa kwesiliva nazo ziyasebenza kumabhodi anezinhlangothi ezimbili.

Inqubo yokufafaza ngothayela: Ukubukeka okuhle, i-solder pad emhlophe esiliva, kulula ukuyithengisa, kulula ukuyithengisa, futhi intengo ephansi.

Inqubo yensimbi yethayela: Ikhwalithi ezinzile, ngokuvamile esetshenziswa lapho kukhona ama-ICs abophayo.

Okuqukethwe okuhlukanisayo

Umehluko phakathi kwebhodi le-PCB elinezinhlangothi ezimbili kanye nebhodi le-PCB elinohlangothi olulodwa ukuthi isekethe yephaneli eyodwa kuphela ohlangothini olulodwa lwebhodi le-PCB, kuyilapho umjikelezo webhodi le-PCB elinamacala amabili ungaxhunywa phakathi kwezinhlangothi ezimbili zebhodi le-PCB ngembobo edlula phakathi nendawo.

Amapharamitha webhodi le-PCB elinezinhlangothi ezimbili ahlukile kulawo webhodi le-PCB elinohlangothi olulodwa. Ngaphezu kwenqubo yokukhiqiza, kukhona nenqubo yokubeka ithusi, okuyinqubo yokuqhuba isifunda esinezinhlangothi ezimbili.
