High Tg board

Lapho izinga lokushisa eliphezulu lebhodi lesifunda le-Tg likhuphuka liye endaweni ethile, i-substrate izoshintsha kusukela "kwisimo sengilazi" ibe "isimo senjoloba", futhi izinga lokushisa ngalesi sikhathi libizwa ngokuthi izinga lokushisa lokushintsha kwengilazi (Tg) yepuleti.Ngamanye amazwi, i-Tg izinga lokushisa eliphakeme kakhulu (℃) lapho i-substrate ihlala iqinile.Okusho ukuthi, izinto ezivamile ze-PCB substrate ekushiseni okuphezulu azikhiqizi kuphela ukuthambisa, ukuguqulwa, ukuncibilika nezinye izenzakalo, kodwa futhi kubonisa ukwehla okubukhali kwezakhiwo zemishini kanye nogesi (angicabangi ukuthi ufuna ukubona imikhiqizo yabo ivela kuleli cala. ).

Amapuleti e-General Tg angaphezu kuka-130 degrees, i-Tg ephakeme ngokuvamile ingaphezu kwama-degree angu-170, kanti i-Tg ephakathi icishe ibe ngaphezu kuka-150 degrees.

Imvamisa, i-PCB ene-Tg≥170℃ ibizwa ngebhodi lesifunda le-Tg eliphakeme.

I-Tg ye-substrate iyanda, futhi ukumelana nokushisa, ukumelana nomswakama, ukumelana namakhemikhali, ukumelana nokuzinza kanye nezinye izici zebhodi lesifunda kuzothuthukiswa futhi kuthuthukiswe.Lapho inani le-TG liphakeme, kuzoba ngcono ukusebenza kokumelana nezinga lokushisa kwepuleti.Ikakhulukazi kwinqubo engenamthofu, i-TG ephezulu ivame ukusetshenziswa.

I-High Tg isho ukumelana nokushisa okuphezulu.Ngokuthuthuka okusheshayo kwemboni ye-elekthronikhi, ikakhulukazi imikhiqizo ye-elekthronikhi emelwe amakhompyutha, ekuthuthukiseni umsebenzi ophezulu, i-multilayer ephezulu, isidingo se-PCB substrate impahla ephakeme ukumelana nokushisa njengesiqinisekiso esibalulekile.Ukuvela nokuthuthukiswa kobuchwepheshe bokufaka ukuminyana okuphezulu okumelelwe i-SMT ne-CMT kwenza i-PCB incike kakhulu ekusekelweni kokumelana nokushisa okuphezulu kwe-substrate ngokuvula indawo encane, izintambo ezinhle kanye nohlobo oluncane.

Ngakho-ke, umehluko phakathi kwe-FR-4 evamile kanye ne-high-TG FR-4 ukuthi esimweni esishisayo, ikakhulukazi ngemva kwe-hygroscopic kanye nokushisa, amandla omshini, ukuqina kwe-dimensional, ukunamathela, ukumuncwa kwamanzi, ukubola okushisayo, ukunwetshwa kokushisa nezinye izimo. izinto zokwakha zihlukile.Imikhiqizo ye-High Tg ngokusobala ingcono kunezinto ezijwayelekile ze-PCB substrate.Eminyakeni yakamuva, inani lamakhasimende adinga ibhodi lesekhethi ye-Tg ephezulu liye landa unyaka nonyaka.
