Ingxenye: izici ezihlukahlukene ezithinta intengo yebhodi le-PCB
Intengo ye-PCB ibilokhu iyindida kubathengi abaningi, futhi abantu abaningi bazozibuza ukuthi lezi ntengo zibalwa kanjani uma kufakwa ama-oda ku-inthanethi. Ake sikhulume ngezingxenye zentengo ye-PCB ndawonye.
- Izinto ezahlukahlukene ezisetshenziswa ku-PCB ziholela emananini ahlukahlukene
Isibonelo, iphaneli ekabili Ejwayelekile, ipuleti ngokuvamile lino-FR4 (Sheng yi, Kingboard, Guoji, amanani amathathu ukusuka phezulu kuye phansi), ukujiya kwepuleti kusuka ku-0.2 mm kuya ku-3.0 mm, ukujiya kwethusi kusuka ku-0.5 oz kuya ku-3 oz, konke lokhu impahla yepuleti ngomehluko omkhulu wamanani; Kuyinki wokumelana, uwoyela we-thermosetting ojwayelekile kanye nowoyela oluhlaza we-photosensitive nakho kukhona umehluko wentengo.
2.Izinqubo ezihlukene zokwelashwa kwendawo ziholela emananini ahlukahlukene
Inqubo evamile yokwelashwa kwendawo: I-OSP (ukumelana ne-oxidation), kukhona i-HASL, i-HASL engenamthofu (ezemvelo), i-plating yegolide, igolide lokucwiliswa kanye nenqubo ethile yokuhlanganisa, njalonjalo, intengo yenqubo ibiza kakhulu esikhathini esizayo.
I-3.PCB ngokwayo ebangelwa ubunzima obuhlukahlukene bokuhlukahluka kwamanani.
Kunezimbobo eziyi-1000 kuwo womabili amabhodi wesekethe. Uma usayizi wembobo webhodi elilodwa mkhulu kuno-0.2mm, ubukhulu bembobo yelinye ibhodi bungaphansi kuka-0.2mm. Uma izinhlobo ezimbili zamabhodi esekethe zifana, kodwa ububanzi bomugqa nesikhala somugqa zihlukile, eyodwa inkulu kuno-4mil kanti enye incane kuno-4mil, kuzophinde kubangele izindleko ezihlukene zokukhiqiza. Okulandelayo kusasele abambalwa abangahambi idizayini ye- common plate craft flow futhi iwukwengeza imali yokuqoqa, isibonelo imbobo ewuhhafu, imbobo yokungcwaba, imbobo yesitsha, cindezela ipuleti likakhiye ukuze uphrinte uwoyela wekhabhoni.
