Chifukwa chiyani mugwiritse ntchito FR-4 kupanga ma Tg PCB apamwamba?

Chifukwa chiyani mumagwiritsa ntchito FR4 kupanga ma Tg PCB apamwamba?

Ntchito zina zimafuna PCB kuti ipirire kutentha kwa 200 ℃ kapena kupitilira apo.Pakuti ntchito odalirika ntchito kutentha kwambiri, tiyenera PCBs odzipereka chopangidwa ntchito zipangizo ntchito yoyendetsedwa.Tsambali lapangidwa kuti likudziwitse PCB imodzi yodzipatulira yotere, yotchedwa HIGH-TG.Izima PCB apamwamba kwambiriimatha kupirira kutentha kwambiri kwa ma PCB pomwe ikupereka izi:

1. Kuwongolera bwino kwa impedance

2. Kuwongolera bwino kwa kutentha

3. Kutsika kwa chinyezi

4. Kuchita kosasinthasintha

FR4 - Zinthu zokondedwa zama Tg PCB apamwamba

Pazotentha kwambiri, ma Tg PCB apamwamba amapangidwa pogwiritsa ntchito magawo a FR-4.Fr-4 ndi malawi obwezeretsanso galasi fiber yolimbitsa epoxy zinthu zomwe zimakhala zozungulira zingapo, zovuta za PCB ndikulola kuwotcherera popanda lead.Magawo wamba a FR-4 amaphatikizapo PTFE yoyera, PTFE yodzaza ndi ceramic, ndi magawo a thermosetting hydrocarbon.Zotsatirazi ndizopadera za gawo lapansi la FR-4 lomwe limapangitsa kuti likhale loyenera kwa ma PCB ofunsira ntchito.

1. Kuchita bwino kwamagetsi.

2. Imatha kupirira pobowola mwapadera ndi plating kudzera mu dzenje (PTH) kukonzekera.

3. Wabwino plating mwa dzenje kudalirika.

4. Mtengo wake ndi wotsika.

5. Stable dissipation factor (Df) poyerekeza ndi zipangizo zina za PCB.

6. Wabwino kukana mankhwala

7. Oyenera PCB kapangidwe amafuna kulamulira okhwima impedance

8. Chosagwedezeka, chotchinjiriza komanso choletsa moto.

Poganizira ntchito yake yapadera pakuwongolera kutentha, ma FR-4 High Tg PCB amasankhidwa kwambiri kuti agwiritsidwe ntchito pamakompyuta, kusungirako ndi zotumphukira, zamagetsi ogula, makina ochezera ndi kulumikizana, ndege ndi chitetezo, zamankhwala, mafakitale & zida, komanso mafakitale agalimoto & zamagetsi.Makampani oyendetsa magalimoto.

Sankhani zida zoyenera kuti mukwaniritse zotsatira zomwe mukufuna

Mwa mitundu yomwe ilipo ya FR-4, ndikofunikira kusankha zinthu zoyenera pazofunikira, chifukwa zimatsimikizira kukhazikika komanso magwiridwe antchito abwino a gawo lomaliza.Zinthu monga dielectric permittivity, coefficient coefficient, thermal conductivity, transition temperature, coefficient of thermal expansion (CTE), magetsi, ndi zina zotero, ziyenera kuganiziridwa musanasankhe magawo a FR-4 kuti mugwiritse ntchito.Ngati mwasokonezeka pamtundu wa zinthu za FR-4 zomwe mungasankhe, ganizirani kugwira ntchito ndi wopanga PCB wodziwa kupereka ma Tg PCB apamwamba ku mafakitale osiyanasiyana.RigiFlex Technologies ndi amodzi mwa odziwika bwinoOpanga PCBpamsika ndipo ali ndi luso lothandizira popereka ma Tg PCB apamwamba pamasinthidwe osiyanasiyana.Funsani mtengo wapamwamba wa Tg PCB tsopano!
