Le zeendawana ebhodi yesekethe High Tg iza kutshintsha ukusuka 'karhulumente iglasi "kwi" karhulumente rubber "xa ubushushu kwindawo ethile, kwaye oku ubushushu ubizwa ngokuba ubushushu yeglasi yenguqu (Tg) yebhodi. Ngamanye amazwi, Tg ke ubushushu iphezulu (℃) apho zeendawana kuhlala ziqinile. Oko kukuthi, abaqhelekileyo izixhobo PCB zeendawana kubushushu eliphezulu bathela yayiya kuphela, deformation, ukunyibilika kunye nezinye izenzakalo, kodwa ukusebenza kwi mechanical, iimpawu zombane of a ukuhla elibukhali (Andiqondi ukuba sifuna ukubona kuvela iimveliso zabo kule meko).

Ngokubanzi, ibhodi ye Tg na ngaphezu kweqondo lama-130, aphezulu Tg na ngaphezu kweqondo lama-170, kunye neliphakathi Tg na ngaphezu kweqondo lama-150.

Ngokuqhelekileyo Tg≥170 ℃ PCB, ebizwa Tg PCB eliphezulu.

Xa Tg na ukunyuka zeendawana, ukumelana ubushushu ibhodi wesiphaluka, ukumelana ukunyakama, ukumelana lwekhemikhali, ukumelana uzinzo kunye nezinye iimpawu ziza kuphuculwa. Ukuba liphakamile ixabiso KT, ngcono kweelana lobushushu nembasa. Kwaye KT ephakamileyo isoloko isetyenziswa kwinkqubo yokukhokela-free,

Tg High ibhekisa uxhathiso high ubushushu. Ngophuhliso ngokukhawuleza kwishishini elektroniki iimveliso ngekhompyutha zimelwe yi computer, kweelana ubushushu ephakamileyo izinto zeendawana PCB zibe yinto siqinisekiso ebalulekileyo xa nophuhliso olusingisa ibe umsebenzi omkhulu multilayer eliphezulu. Yiyiphi eyona, ukuvela kunye nophuhliso uqhagamshelwano lwetshiphu emsebenzi-mninzi ufakelo iteknoloji emelwe SMT kunye CMT ukwenza PCB ngakumbi engenakususwa ngakumbi kwinkxaso yokuxhathisa ubushushu ophezulu zeendawana e imbobo encinane, beesekethe ecikizekileyo kunye nefomu ebhityile.

Ngoko ke, umahluko phakathi fr-4 jikelele kunye Tg fr-4 phezulu kukuba ngokwaseburhulumenteni thermal, ingakumbi kwimeko ubushushu emva ukufuma ukufunxeka. Kwaye kukho umahluko emininzi amandla mechanical, uzinzo mbini, adhesion, ukufakwa kwamanzi, ibole thermal, ukwanda thermal kunye neminye imiqathango izinto. Iimveliso eliphezulu Tg ke kungcono kunokuba izinto eziqhelekileyo PCB zeendawana. Kwiminyaka yakutshanje, inani abathengi efuna imveliso ibhodi yesekethe Tg high lenyuke ngonyaka ngeminyaka.
