Isicelo

Inani le-TG libhekisela kuzinga lokushisa lokushintsha kwengilazi (Tg), okuyipharamitha ebalulekile yokuzinza okushisayo nokumelana nokushisa kwamabhodi e-PCB.Amabhodi e-PCB anamanani ahlukene e-TG anezakhiwo ezihlukene nezimo zohlelo lokusebenza.Nansi eminye yemibono evamile:

1. Ukuphakama kwevelu ye-Tg, kuba ngcono ukumelana nezinga lokushisa eliphezulu kwebhodi le-PCB, elifanele izimo zohlelo lokusebenza ezindaweni ezishisa kakhulu, ezifana nogesi wezimoto, ukulawulwa kwezimboni nezinye izinkambu.

2. Lapho inani le-Tg liphakeme, kuba ngcono izici zomshini zebhodi le-PCB, futhi izinkomba zamandla njengokugoba, ukuqina, nokugunda zingcono kunezo zebhodi le-PCB elinenani eliphansi le-Tg.Ifanele izinsimbi ezinembayo nemishini edinga ukuzinza okuphezulu.

3. Izindleko zamabhodi e-PCB anevelu ye-Tg ephansi ziphansi uma kuqhathaniswa, ezifanele ezinye izimo zohlelo lokusebenza ezinezidingo eziphansi zokusebenza kanye nokulawulwa kwezindleko okuqinile, okufana nogesi wabathengi.Kafushane, ukukhetha ibhodi le-PCB elifanele isimo sakho sohlelo lokusebenza kuzosiza ukuthuthukisa ikhwalithi yomkhiqizo nokuzinza futhi kunciphise izindleko zokukhiqiza.

4. Ibhodi lesifunda eliphrintiwe le-tg150 lisho ibhodi lesifunda elakhiwe ngebhodi le-tg150.I-TG ivamise ukusho izinga lokushisa lengilazi elishintshashintshayo, elisho ushintsho olungaguquguquki oluhlehlayo lwento e-amorphous ukusuka esimweni esiqinile “nesengilazi” ukuya esimweni senjoloba nesibukekayo lapho kufakwa amazinga okushisa angaphezulu kwalindelekile.Ngenkathi i-TG ivame ukufakazela ukuthi iphansi kunezinga lokushisa elincibilikayo lesimo se-crystalline esihambisanayo.

5. Izinga lokushisa elishintshashintshayo lengilazi livame ukuza njengento engashi, ehlanekezela/encibilika kumazinga okushisa athile.I-tg150 PCB iza njengempahla ye-TG emaphakathi ngoba iwela ngaphezu kobubanzi obungu-130 degrees Celsius ukuya ku-140 degrees Celsius kodwa ibe ngaphansi kuka-170 degree Celsius okulingana noma ngaphezulu.Sicela uqaphele ukuthi ukuphakama kwe-TG ye-substrate (imvamisa i-epoxy), kuyanda ukuzinza kwebhodi lesifunda eliphrintiwe.

Imibuzo Evame Ukubuzwa

1.Iyini i-Tg yama-PCB?

Ukushisa okudingekayo kokuqina kwe-PREPREG kufanele kusetshenziswe ngaphandle kokudlula i-FR4 Tg ukuze kulondolozwe ukuzinza kwe-PCB.I-FR4 Tg ejwayelekile iphakathi kuka-130 – 140°C, i-Median Tg ingu-150 °C kanti i-Tg ephakeme ingaphezu kuka-170°C.

2.Ungakhetha kanjani i-Tg ye-PCB?

I-Standard Tg ihlala ngaphezu kuka-130℃ kuyilapho i-Tg iphezulu ngaphezu kuka-170℃ kanye ne-Tg emaphakathi ngaphezu kuka-150℃.Uma kukhulunywa ngezinto ezisetshenziswayo zama-PCB, kufanele kukhethwe i-Tg ephezulu, okufanele ibe ngaphezu kwezinga lokushisa elisebenzayo lamanje.

3.Iyini i-tg150?

I-tg150 PCB iza njengempahla ye-TG emaphakathi ngoba iwela ngaphezu kobubanzi obungu-130 degrees Celsius ukuya ku-140 degrees Celsius kodwa ibe ngaphansi kuka-170 degree Celsius okulingana noma ngaphezulu.Sicela uqaphele ukuthi ukuphakama kwe-TG ye-substrate (imvamisa i-epoxy), kuyanda ukuzinza kwebhodi lesifunda eliphrintiwe.

4.Uyini umehluko phakathi kwe-Tg 150 kanye ne-tg170?

Isici esikhulu sokucabangela ukuthi ukusetshenziswa kwe-150 noma 170 Tg PCB yizinga lokushisa elisebenzayo.Uma ingaphansi kuka-130C/140C, khona-ke okokusebenza kwe-Tg 150 kulungile ku-PCB yakho;kodwa uma izinga lokushisa lokusebenza lizungeze i-150C, kufanele ukhethe i-170 Tg.

5.Iyini impahla ephezulu ye-Tg PCB?

I-Tg PCB ephezulu iqukethe isistimu ye-resin edizayinelwe ukuthi imelane nokusoda okungenamthofu futhi inike amandla amandla omshini aphezulu ezindaweni zokushisa ezinokhahlo, eziphakeme.I-resin ibhekisela kunoma iyiphi into ephilayo eqinile noma e-semiolid evame ukusetshenziswa kumapulasitiki, amavanisha, njll.
