Kubwera kwa ma 5G olumikizirana ma cellular kwadzetsa kukambirana za kumanga mabwalo othamanga a digito padziko lonse lapansi.Mainjiniya akufufuza njira zabwino zotumizira ma siginecha ndi ma frequency kudzera pazida zamakono zama board osindikizidwa (PCBs).

Cholinga cha zipangizo zonse PCB ndi kufalitsa magetsi ndi kupereka kutchinjiriza pakati mkuwa kuchititsa zigawo.Zomwe zimapezeka kwambiri pagululi ndi FR-4.Komabe, zofunikira za bolodi lanu zidzakhudzidwa ndi zinthu zosiyanasiyana za PCB.Chitsogozo chosankha zinthu za PCB chomwe chili pansipa, chopangidwa ndi ABIS, katswiri wopanga PCB wazaka zopitilira 15, angakuuzeni zomwe muyenera kuyang'ana pankhani yamitundu yosiyanasiyana ya PCB.

Mapangidwe a board odziwika bwino amaphatikiza zigawo zapakati za dielectric substrate core komanso zigawo za dielectric laminated.Zigawo za laminate zidzakhala maziko a zojambula zamkuwa ndi ndege zamphamvu.Zigawozi, zomwe zimagwira ntchito ngati kutchinjiriza pakati pa zigawo za conductive zamkuwa ndikulola kuti magetsi aziyenda, amapangidwa kuchokera kuzinthu zosiyanasiyana kutengera zomwe ali nazo.Ma metric angapo amagwiritsidwa ntchito kusanthula kutentha ndi magetsi azinthuzo kuti adziwe zida zoyenera za magawo apakati apansi ndi laminate.Komanso, mbali zina monga mankhwala makhalidwe ndi makina katundu ayenera kuunika malinga ndi ntchito payekha, popeza PCB angagwiritsidwe ntchito makina ndi zigawo zikuluzikulu kuti akhoza poyera kuchuluka kwa chinyezi kapena kuika m'madera zolimba kuti amafuna osinthasintha PCBs.

Kuyeza kwa dielectric constant (Dk) kumagwiritsidwa ntchito kudziwa momwe magetsi amagwirira ntchito PCB yothamanga kwambiri zakuthupi.Kuti mugwire ntchito ngati zotsekera pama trace amkuwa ndi ndege zamagetsi, mukufuna zinthu zokhala ndi ma Dk otsika pamagawo a PCB.Zomwe zasankhidwa ziyeneranso kusunga kuti Dk yake ikhale yosasinthasintha momwe zingathere pa nthawi ya moyo wake pamitundu yosiyanasiyana ya ma frequency.Zinthu zomwe zimatsimikizira magwiridwe antchito amagetsi a zida za dielectric zomwe zimagwiritsidwa ntchito mu ma PCB ndi kukhulupirika kwa ma sign ndi impedance.

Pamodzi ndi PCB, kutentha kumapangidwa pamene ikuyendetsa magetsi.Zida zidzawonongeka pamitengo yosiyanasiyana chifukwa cha kutentha kwa kutentha kumeneku kudzayika pazitsulo zotumizira, zigawo, ndi zipangizo za dielectric.Kuphatikiza apo, kutentha kumatha kupangitsa kuti zida zina ziwonjezeke, zomwe sizoyipa kwa ma PCB chifukwa zimatha kuyambitsa kulephera komanso kusweka.

Poyesa kukana kwa mankhwala, mtundu wa malo omwe gulu lozungulira lidzagwiritsidwe ntchito ndilofunika.Zomwe mumasankha ziyenera kukhala ndi mphamvu zokana mankhwala komanso zimayamwa pang'ono chinyezi.Kuphatikiza apo, mainjiniya amayenera kuyang'ana zida zomwe zili ndi mphamvu zoletsa malawi, zomwe zikutanthauza kuti sizidzayaka kwa masekondi 10 mpaka 50 pakuyaka lawi.Zigawo za PCB zitha kuyambanso kupatukana pa kutentha kwina, chifukwa chake ndikofunikira kudziwa izi zikachitika.

Mukasankha zida zoyenera, kuyika ndalama zoyenera, ndikuwunika zolakwika zopanga, mutha kukhala ndi zaka zambiri zopanda vuto kuchokera pagulu lanu losindikizidwa.Ma Circuits a ABIS amapereka mapepala apamwamba osindikizidwa.PCB iliyonse yomwe timapereka ndi yamtengo wapatali komanso yopangidwa mwaluso.Kuti mudziwe zambiri za ma PCB athu, chonde LUMIKIZANANI NAFE .
