Kugwiritsa ntchito
High Layer PCB (High Layer PCB) ndi PCB (Printed Circuit Board, bolodi losindikizidwa) yokhala ndi zigawo zopitilira 8.Chifukwa cha ubwino wake Mipikisano wosanjikiza bolodi dera, apamwamba kachulukidwe dera chingapezeke mu phazi ang'onoang'ono, kulola kamangidwe ka dera zovuta kwambiri, choncho ndi oyenera mkulu-liwiro digito chizindikiro processing, mayikirowevu wailesi pafupipafupi, modemu, mkulu-mapeto. seva, kusungirako deta ndi magawo ena.Ma board ozungulira apamwamba nthawi zambiri amapangidwa ndi matabwa apamwamba a TG FR4 kapena zida zina zapansi panthaka, zomwe zimatha kukhazikika m'malo otentha kwambiri, chinyezi chambiri, komanso ma frequency apamwamba.
Pankhani ya TG yazinthu za FR4
FR-4 gawo lapansi ndi epoxy resin system, kotero kwa nthawi yayitali, mtengo wa Tg ndiye index yodziwika kwambiri yomwe imagwiritsidwa ntchito kugawa gawo la gawo la FR-4, ndi chimodzi mwazinthu zofunikira kwambiri pakuwunika kwa IPC-4101, Tg. mtengo wa utomoni, umatanthawuza zinthu zomwe zimachoka pamalo olimba kapena "galasi" kupita kumalo opunduka mosavuta kapena kufewetsa kutentha kwanyengo.Kusintha kwa thermodynamic uku kumasinthidwa nthawi zonse bola utomoni suwola.Izi zikutanthauza kuti chinthu chikatenthedwa kuchokera kutentha kupita ku kutentha pamwamba pa mtengo wa Tg, ndiyeno itakhazikika pansi pa mtengo wa Tg, ikhoza kubwerera ku chikhalidwe chake cham'mbuyo chokhala ndi zinthu zomwezo.
Komabe, zinthu zikatenthedwa mpaka kutentha kwambiri kuposa mtengo wake wa Tg, kusintha kosasinthika kumatha kuchitika.Zotsatira za kutentha kumeneku zimakhudzana kwambiri ndi mtundu wa zinthu, komanso ndi kuwonongeka kwa kutentha kwa utomoni.Nthawi zambiri, kuchuluka kwa Tg kwa gawo lapansi kumapangitsa kuti zinthuzo zikhale zodalirika.Ngati njira yowotcherera yopanda kutsogolera itengedwa, kutentha kwa kutentha kwapakati (Td) kwa gawo lapansi kuyeneranso kuganiziridwa.Zizindikiro zina zofunika kwambiri zogwirira ntchito ndi monga matenthedwe owonjezera amafuta (CTE), kuyamwa kwamadzi, kumatira kwa zinthuzo, komanso mayeso omwe amagwiritsidwa ntchito nthawi zambiri monga mayeso a T260 ndi T288.
Kusiyana koonekeratu pakati pa zida za FR-4 ndi mtengo wa Tg.Malinga ndi kutentha kwa Tg, FR-4 PCB nthawi zambiri imagawidwa kukhala Tg yotsika, Tg yapakatikati ndi ma Tg apamwamba.M'makampani, FR-4 yokhala ndi Tg yozungulira 135 ℃ nthawi zambiri imatchedwa Tg PCB yotsika;FR-4 pafupifupi 150 ℃ idasinthidwa kukhala yapakati Tg PCB.FR-4 yokhala ndi Tg yozungulira 170 ℃ idasankhidwa kukhala Tg PCB yapamwamba.Ngati pali nthawi zambiri zokanikiza, kapena zigawo za PCB (zoposa 14 zigawo), kapena kutentha kwakukulu kwa kuwotcherera (≥230 ℃), kapena kutentha kwakukulu kogwira ntchito (kuposa 100 ℃), kapena kupsinjika kwakukulu kwa kutentha (monga kutenthetsa kutentha), high Tg PCB iyenera kusankhidwa.
FAQs
Kuphatikizana kolimba kumeneku kumapangitsanso kuti HASL ikhale yomaliza bwino pamapulogalamu odalirika kwambiri.Komabe, HASL imasiya malo osagwirizana ngakhale ikuwongolera.ENIG, kumbali ina, imapereka malo athyathyathya kwambiri omwe amapangitsa ENIG kukhala yabwino pamawu abwino komanso mapini apamwamba makamaka zida za ball-grid array (BGA).
