PCB e tlameha ho mamella mollo 'me e ke ke ea cha ka mocheso o itseng, feela hore e be bonolo. Sebaka sa mocheso ka nako ena se bitsoa mocheso oa phetoho ea khalase (TG ntlha), e amanang le botsitso ba boholo ba PCB.

TG PCB e phahameng ke efe le melemo ea ho sebelisa TG PCB e phahameng?

Ha mocheso o phahameng oa TG PCB o nyolohela ho tse itseng, substrate e tla fetoha ho tloha "boemo ba khalase" ho "rabara boemo", joale mocheso ka nako ena o bitsoa mocheso oa vitrification (TG) oa boto. Ka mantsoe a mang, TG ke mocheso o phahameng ka ho fetisisa oo substrate e lulang e tiile.

PCB board e na le mofuta ofe ka ho khetheha?

Boemo ho tloha tlase ho ea holimo bo bonts'a ka tlase:

94HB - 94VO - 22F - CEM-1 - CEM-3 - FR-4

Lintlha ke tse latelang:

94HB: k'hateboto e tloaelehileng, eseng e sa chese mollo (lisebelisoa tsa maemo a tlase-tlase, litebele tsa lefu, li ke ke tsa etsoa boto ea matla)

94V0: khateboto e thibelang lelakabe (ho phunya)

22F: fiberboard ea khalase e nang le lehlakore le le leng (ho phunya)

CEM-1: boto ea fiberglass e nang le lehlakore le le leng (ho cheka komporo ho tlameha ho etsoa, ​​eseng ho phunya)

CEM-3: boto ea fiberglass e nang le mahlakore a mabeli (thepa e tlaase ka ho fetisisa ea boto e nang le mahlakoreng a mabeli ntle le boto e mahlakoreng a mabeli, thepa ena e ka sebelisoa bakeng sa liphanele tse peli, tse theko e tlaase ho feta FR4)

FR4: boto ea fiberglass e mahlakoreng a mabeli
