High Tg board

Iyo ubushyuhe bwikibaho kinini cya Tg buzamutse mukarere runaka, substrate izahinduka kuva "ikirahuri" ihinduka "reberi", kandi ubushyuhe muriki gihe bwitwa ubushyuhe bwikirahure (Tg) bwisahani.Muyandi magambo, Tg nubushyuhe bwo hejuru (℃) aho substrate ikomeza gukomera.Nukuvuga, ibikoresho bisanzwe bya PCB mubushyuhe bwo hejuru ntibitanga gusa koroshya, guhindura ibintu, gushonga nibindi bintu, ariko kandi byerekana kugabanuka gukabije kumashanyarazi na mashanyarazi (sinkeka ko ushaka kubona ibicuruzwa byabo bigaragara muriki kibazo ).

Amasahani rusange ya Tg arenga dogere 130, hejuru ya Tg muri rusange irenga dogere 170, naho Tg yo hagati ni dogere zirenga 150.

Mubisanzwe, PCB hamwe na Tg≥170 ℃ yitwa ikibaho kinini cya Tg.

Tg ya substrate iriyongera, kandi kurwanya ubushyuhe, kurwanya ubushuhe, kurwanya imiti, kurwanya ituze nibindi biranga ikibaho cyumuzunguruko bizanozwa kandi bitezimbere.Hejuru ya TG agaciro, nibyiza gukora ubushyuhe bwo kurwanya isahani.Cyane cyane muburyo butayobora, TG yo hejuru ikoreshwa.

Hejuru ya Tg bivuga ubushyuhe bwinshi.Hamwe niterambere ryihuse ryinganda za elegitoronike, cyane cyane ibicuruzwa bya elegitoronike bihagarariwe na mudasobwa, biganisha ku iterambere ryimikorere ihanitse, igizwe n'abantu benshi, gukenera ibikoresho bya PCB munsi yubushyuhe bukabije nkubwishingizi bwingenzi.Kugaragara no guteza imbere tekinoroji yubushakashatsi bwimbitse ihagarariwe na SMT na CMT ituma PCB irushaho gushingira kumfashanyo irwanya ubushyuhe bukabije bwa substrate mubijyanye na aperture ntoya, insinga nziza nubwoko bworoshye.

Kubwibyo rero, itandukaniro riri hagati ya FR-4 isanzwe na TG FR-4 ni uko mumiterere yubushyuhe, cyane cyane nyuma ya hygroscopique no gushyuha, imbaraga za mashini, ituze ryimiterere, gufatira hamwe, kwinjiza amazi, kubora ubushyuhe, kwaguka kwinshi nubundi buryo bwa ibikoresho biratandukanye.Ibicuruzwa byinshi bya Tg biragaragara ko ari byiza kuruta ibikoresho bisanzwe bya PCB.Mu myaka yashize, umubare wabakiriya bakeneye Tg umuzunguruko muremure wiyongereye uko umwaka utashye.
