10 Umaleko ENIG FR4 Tg150 PCB
Phezulu Tg PCB
I-Glass Transition Temperature (Tg) yenye yezona zinto zibalulekileyo kuyo nayiphi na i-epoxy kwaye ngummandla wobushushu apho i-polymer itshintsha ukusuka kwi-hard, i-glass material ukuya kwi-soft, i-rubbery material.
Xa ubushushu bokusebenza bufikelela kwindawo yokunyibilika, oko kuthetha ukuba iqondo lobushushu lidlula ixabiso le-Tg, imeko yezinto zePCB iya kutshintshwa ukusuka kwiglasi ukuya kulwelo, nto leyo eya kuchaphazela umsebenzi wePCB.Kwaye eli xabiso linxulumene nokuzinza kwe-PCB dimension.
Njengesiqhelo, yenziwe nge Tg ≥ 170℃ PCB imathiriyeli, ebizwa ngokuba yibhodi yesekethe ephezulu Tg eprintiweyo.Ngophuhliso olukhawulezayo lweshishini lombane, izinto eziphezulu zeTg zisetyenziswa kakhulu kwiikhompyuter, izixhobo zonxibelelwano, izixhobo ezichanekileyo, kunye nezixhobo, njl.
Uzahlula njani izixhobo zePCB eziPhezulu zeTg
| Izinto eziphathekayo | Tg | Mot |
| Tg eqhelekileyo | 130℃ | 110 |
| I-Tg ePhakathi | 150℃ | 130 |
| Phezulu Tg | 170℃ | 150 |
| polyimide-Ultra high Tg | 260℃ | 240 |
Ukusetyenziswa kwe-High Tg PCB
Ukuphakama kweTg, ngcono ukusebenza kwePCB ukumelana nobushushu, ukuxhathisa ukufuma, ukuxhathisa imichiza, ukuzinza kunye nezinye iimpawu.
