Ƙimar TG tana nufin zafin canjin gilashin (Tg), wanda shine muhimmin ma'auni don kwanciyar hankali na thermal da juriya na zafi na allon PCB.Allolin PCB masu kimar TG daban-daban suna da kaddarori daban-daban da yanayin aikace-aikace.Ga wasu bambance-bambancen gama gari:
1. Mafi girman darajar Tg, mafi kyawun tsayayyar zafin jiki na kwamitin PCB, wanda ya dace da yanayin aikace-aikacen a cikin yanayin zafi mai zafi, irin su na'urorin lantarki, sarrafa masana'antu da sauran filayen.
2. Mafi girman darajar Tg, mafi kyawun kayan aikin injiniya na kwamitin PCB, da kuma alamun ƙarfi kamar lankwasawa, ƙwanƙwasa, da shearing sun fi na PCB board tare da ƙananan darajar Tg.Ya dace da daidaitattun kayan aiki da kayan aiki waɗanda ke buƙatar babban kwanciyar hankali.
3.

4. Tg150 da aka buga yana nuna allon da'ira da aka haɓaka tare da allon tg150.TG sau da yawa yana nuna yanayin canjin gilashin, wanda ke nufin ci gaba da jujjuyawar canjin abu na amorphous daga yanayi mai ƙarfi da “gilashi” zuwa yanayin rubbery da ɗanɗano yayin aikace-aikacen yanayin zafi sama da yadda ake tsammani.Duk da yake TG sau da yawa yana tabbatar da ƙasa fiye da yanayin narkewar yanayin kayan crystalline daidai.
5. Gilashin yanayin zafin jiki na tsaka-tsakin sau da yawa yakan zo azaman abu mai jurewa ƙonawa, murdiya / narkewa a takamaiman yanayin zafin jiki.Tg150 PCB ya zo a matsayin matsakaiciyar kayan TG saboda ya faɗi sama da kewayon digiri 130 Celsius zuwa digiri 140 ma'aunin celcius tukuna ƙasa da digiri 170 ma'aunin celcius daidai ko sama.Lura cewa mafi girman TG na ma'auni (yawanci epoxy), mafi girman kwanciyar hankali na allon da'ira.
FAQs
Dole ne a yi amfani da zafin da ake buƙata don tsaurin PREPREG ba tare da wuce FR4 Tg ba don kiyaye kwanciyar hankali na PCB.Ma'aunin FR4 Tg yana tsakanin 130 - 140 ° C, Tg na tsakiya shine 150 ° C kuma babban Tg ya fi 170 ° C.
Madaidaicin Tg yana tsayawa sama da 130 ℃ yayin da babban Tg sama da 170 ℃ da tsakiyar Tg sama da 150 ℃.Lokacin da yazo ga kayan PCBs, yakamata a ɗauki babban Tg, wanda yakamata ya zama mafi girma fiye da yanayin zafin aiki na yanzu.
Tg150 PCB ya zo a matsayin matsakaiciyar kayan TG saboda ya faɗi sama da kewayon digiri 130 Celsius zuwa digiri 140 ma'aunin celcius tukuna ƙasa da digiri 170 ma'aunin celcius daidai ko sama.Lura cewa mafi girman TG na ma'auni (yawanci epoxy), mafi girman kwanciyar hankali na allon da'ira.
Babban abin da za a yi la'akari da ko amfani da 150 ko 170 Tg PCB abu shine zafin aiki.Idan ƙasa da 130C/140C, to Tg 150 abu yayi kyau ga PCB ɗin ku;amma idan zafin aiki yana kusa da 150C, to dole ne ku zaɓi 170 Tg.
Babban Tg PCB yana ƙunshe da tsarin guduro wanda aka ƙera don jure wa siyar da babu gubar kuma yana ba da ƙarfin injina mafi girma a cikin matsananci, yanayin zafi mafi girma.Resin yana nufin duk wani abu mai ƙarfi ko mai ƙarfi wanda galibi ana amfani dashi a cikin robobi, varnishes, da sauransu.
