Application
Iko kukosha kweTG kunoreva tembiricha yegirazi yekuchinja (Tg), inova yakakosha parameter yekudzikama kwekupisa uye kupisa kupisa kwePCB board.PCB mabhodhi ane akasiyana TG maitiro ane akasiyana zvivakwa uye mamiriro ekushandisa.Heano mimwe misiyano yakajairika:
1. Iyo yakakwirira yeTg kukosha, zviri nani kupikisa kwekushisa kwePCB board, iyo inokodzera mamiriro ekushandiswa munzvimbo dzakakwirira dzekushisa, dzakadai semagetsi emotokari, kutonga kwemaindasitiri nemamwe minda.
2. Iyo yakakwirira yeTg kukosha, zviri nani michina yePCB bhodhi, uye zviratidzo zvesimba zvakadai sekukotama, tensile, uye kuveura zviri nani pane izvo zvePCB board ine Tg yakaderera.Inokodzera midziyo chaiyo uye midziyo inoda kugadzikana kwepamusoro.
3. Mutengo wePCB mabhodhi ane Tg yakaderera yakaderera, iyo yakakodzera kune mamwe mamiriro ekushandisa ane yakaderera kuita zvinodiwa uye kuomesesa kwekudzora mutengo, senge mutengi wemagetsi.Muchidimbu, kusarudza bhodhi rePCB rakakodzera kune yako mamiriro ekushandisa kuchabatsira kuvandudza kunaka kwechigadzirwa uye kugadzikana uye kuderedza mutengo wekugadzira.
4. Iyo tg150 yakadhindwa yedunhu bhodhi inoreva bhodhi redunhu rakagadzirwa ne tg150 bhodhi.TG inowanzoreva tembiricha yekushanduka kwegirazi, iyo inoreva kuchinjika kwakadzikama kweamorphous zvinhu kubva kune yakasimba uye "yegirazi" mamiriro kuenda kune inorabha uye viscous state pakushandiswa kwepamusoro pane inotarisirwa tembiricha.Nepo iyo TG inowanzo ratidza yakaderera pane kunyunguduka tembiricha yeinoenderana crystalline zvinhu mamiriro.
5. Girazi rinoshandura tembiricha zvinhu zvinowanzouya sechinhu chinopisa chinopisa, chinokanganisa/kunyungudika pamatembiricha chaiwo.Tg150 PCB inouya iri yepakati TG zvinhu nekuti inowira pamusoro pemhando ye130 degrees Celsius kusvika 140 degrees Celsius asi iri pasi pe170 degree Celsius yakaenzana kana kupfuura.Ndokumbira utarise kuti iyo yakakwira TG ye substrate (kazhinji epoxy), iyo inokwirisa kugadzikana kweakadhindwa redunhu bhodhi.
FAQs
Kupisa kunodiwa kwePREPREG kusimba kunofanira kushandiswa pasina kudarika FR4 Tg kuchengetedza PCB kugadzikana.Iyo yakajairwa FR4 Tg iri pakati pe130 - 140°C, iyo yepakati Tg i150 °C uye yakakwira Tg yakakura kupfuura 170°C.
Standard Tg inogara pamusoro pe130 ℃ uku ichikwira Tg pamusoro pe170 ℃ uye yepakati Tg pamusoro pe150 ℃.Kana zvasvika kune zvinhu zvePCBs, yakakwira Tg inofanirwa kutorwa, iyo inofanirwa kunge yakakwira kupfuura tembiricha yekushanda ikozvino inomhanya.
Tg150 PCB inouya iri yepakati TG zvinhu nekuti inowira pamusoro pemhando ye130 degrees Celsius kusvika 140 degrees Celsius asi iri pasi pe170 degree Celsius yakaenzana kana kupfuura.Ndokumbira utarise kuti iyo yakakwira TG ye substrate (kazhinji epoxy), iyo inokwirisa kugadzikana kweakadhindwa redunhu bhodhi.
Chinhu chikuru chekufunga kana kushandisa 150 kana 170 Tg PCB zvinhu ndiyo tembiricha yekushanda.Kana iri isingasviki 130C/140C, ipapo Tg 150 zvinhu zvakanaka nokuda PCB yako;asi kana tembiricha yekushanda yakatenderedza 150C, saka unofanirwa kusarudza 170 Tg.
Iyo yakakwira Tg PCB ine resin sisitimu yakagadzirirwa kumira mutobvu-isina soldering uye inogonesa yakakwirira mechanicha simba munzvimbo dzakaoma, dzepamusoro tembiricha.Resin inoreva chero chinhu chakasimba kana semisolid organic chinowanzoshandiswa mumapurasitiki, mavarnish, nezvimwe.
