Isicelo

Ixabiso le-TG libhekisela kwiqondo lokushisa lokutshintsha kweglasi (Tg), eyona parameter ibalulekileyo yokuzinza kwe-thermal kunye nokumelana nobushushu kwiibhodi ze-PCB.Iibhodi ze-PCB ezinamaxabiso ahlukeneyo e-TG zineepropati ezahlukeneyo kunye neemeko zesicelo.Nazi ezinye iiyantlukwano eziqhelekileyo:

1. Ukuphakama kwexabiso le-Tg, bhetele ukumelana nobushushu obuphezulu bebhodi ye-PCB, efanelekileyo kwiimeko zesicelo kwiindawo zokushisa eziphezulu, ezifana ne-automotive electronics, ulawulo lwamashishini kunye nezinye iinkalo.

2. Ukuphakama kwexabiso le-Tg, ngcono iimpawu zemishini yebhodi ye-PCB, kunye nezalathi zamandla ezifana nokugoba, ukugoba, kunye nokucheba zingcono kunezo zebhodi ye-PCB enexabiso eliphantsi le-Tg.Ifanelekile kwizixhobo ezichanekileyo kunye nezixhobo ezifuna ukuzinza okuphezulu.

3. Iindleko zeebhodi ze-PCB ezinexabiso eliphantsi le-Tg lingaphantsi, elifanelekile kwezinye iimeko zesicelo kunye neemfuno eziphantsi zokusebenza kunye nokulawulwa kweendleko ezingqongqo, ezifana ne-electronics yabathengi.Ngamafutshane, ukukhetha ibhodi yePCB efanelekileyo kwimeko yakho yesicelo kuya kunceda ukuphucula umgangatho wemveliso kunye nokuzinza kunye nokunciphisa iindleko zemveliso.

4. Ibhodi yesekethe eprintiweyo ye-tg150 ithetha ibhodi yesekethe eyenziwe ngebhodi ye-tg150.I-TG ihlala ithetha iqondo lobushushu beglasi, elibhekiselele kutshintsho oluzinzileyo lwemathiriyeli ye-amorphous ukusuka esomeleleyo kunye nemeko "ebuglasi" ukuya kwimo yerabha kunye ne-viscous xa kugalelwa amaqondo obushushu aphezulu kunokulindelekileyo.Ngelixa i-TG ihlala ingqina ukuba isezantsi kunobushushu obunyibilikayo bemeko ye-crystalline ehambelanayo.

5. Isixhobo seglasi esitshintshayo seqondo lobushushu sihlala sivela njengesixhobo esingatshiyo, sigqwetheke/ sinyibilike kumazinga athile obushushu.I-tg150 PCB iza njengemathiriyeli ye-TG ephakathi kuba iwela ngaphezu koluhlu lwe-130 degrees Celsius ukuya kwi-140 degrees Celsius kodwa ibe ngaphantsi kwe-170 degree Celsius ngokulingana okanye ngaphezulu.Nceda uqaphele ukuba i-TG ephezulu ye-substrate (ngokuqhelekileyo i-epoxy), iphezulu ukuzinza kwebhodi yesekethe eprintiweyo.

Ii-FAQs

1.Yintoni iTg yeePCBs?

Ukushisa okufunekayo kwi-PREPREG ukuqina kufuneka kusetyenziswe ngaphandle kokudlula i-FR4 Tg ukugcina ukuzinza kwe-PCB.Umgangatho we-FR4 Tg uphakathi kwe-130 - 140 ° C, i-median Tg yi-150 ° C kwaye i-Tg ephakamileyo inkulu kune-170 ° C.

2.Indlela yokukhetha iTg yePCB?

I-Tg esemgangathweni ihlala ngaphezulu kwe-130℃ ngelixa i-Tg iphezulu ngaphezulu kwe-170℃ kunye ne-Tg ephakathi ngaphezulu kwe-150℃.Xa kuziwa kwimathiriyeli yePCBs, iTg ephezulu kufuneka ithathwe, ekufuneka ibephezulu kunobushushu obusebenzayo bangoku.

3.Yintoni i-tg150?

I-tg150 PCB iza njengemathiriyeli ye-TG ephakathi kuba iwela ngaphezu koluhlu lwe-130 degrees Celsius ukuya kwi-140 degrees Celsius kodwa ibe ngaphantsi kwe-170 degree Celsius ngokulingana okanye ngaphezulu.Nceda uqaphele ukuba i-TG ephezulu ye-substrate (ngokuqhelekileyo i-epoxy), iphezulu ukuzinza kwebhodi yesekethe eprintiweyo.

4.Nguwuphi umahluko phakathi kwe-Tg 150 kunye ne-tg170?

Eyona nto iphambili ekufuneka iqwalaselwe ukuba ingaba ukusebenzisa i-150 okanye i-170 Tg PCB imathiriyeli bubushushu obusebenzayo.Ukuba ingaphantsi kwe-130C/140C, ngoko ke Tg 150 imathiriyeli ilungile kwiPCB yakho;kodwa ukuba ubushushu bokusebenza bujikeleze i-150C, kuya kufuneka ukhethe i-170 Tg.

5.Yintoni i-Tg ephezulu ye-PCB imathiriyeli?

I-Tg PCB ephezulu iqulethe inkqubo ye-resin eyilelwe ukumelana ne-solder-free soldering kwaye yenza amandla omatshini aphezulu kwiindawo ezinobushushu obuphezulu.I-resin ibhekisa kuyo nayiphi na into eqinileyo okanye i-semisolid organic ehlala isetyenziswa kwiiplastiki, ivanishi, njl.
