Ibicuruzwa byumye bigomba! PCB ingabo ya PCB izi umubare

Turashobora kubona gukingira PCBS nyinshi, cyane cyane mubikoresho bya elegitoroniki nka terefone igendanwa. PCB ya terefone yuzuye ingabo.

Igipfukisho cyo gukingira kiboneka cyane muri terefone igendanwa PCBS, cyane cyane ko terefone zigendanwa zifite imiyoboro itandukanye y’itumanaho ridafite insinga, nka GPS, BT, WiFi, 2G / 3G / 4G / 5G, hamwe na sisitemu zimwe na zimwe zisa na analogi hamwe na DC-DC ihinduranya amashanyarazi mubisanzwe bikenera kwigunga hamwe nigipfukisho gikingira. Ku ruhande rumwe, ntabwo bigira ingaruka ku zindi nzitizi, ku rundi ruhande, zibuza izindi nzitizi kutagira ingaruka kuri bo.

Iyi ni imwe mu mirimo yo kurinda amashanyarazi ya interineti; Ikindi gikorwa cyingabo ni ukurinda kugongana. PCB SMT izaba igabanijwemo imbaho ​​nyinshi. Mubisanzwe, amasahani yegeranye agomba gutandukanywa kugirango yirinde kugongana hafi mugihe cyo kugerageza cyangwa ubundi bwikorezi.

Ibikoresho fatizo byingabo ni umuringa wera, ibyuma bidafite ingese, tinplate, nibindi. Kugeza ubu, ingabo nyinshi zikoreshwa mumuringa wera.

Umuringa wera urangwa ningaruka nkeya yo gukingira, yoroshye, ihenze kuruta ibyuma bitagira umwanda, byoroshye amabati; Ingaruka yo gukingira ibyuma nibyiza, imbaraga nyinshi, igiciro giciriritse; Nubwo bimeze bityo ariko, biragoye gutobora (ntibishobora kuba amabati bitavuwe hejuru, kandi biratera imbere nyuma yo gushyirwaho nikel, ariko biracyari byiza kubishishwa); Ingaruka yo gukingira tinplate ningaruka mbi, ariko amabati ni meza kandi igiciro kirahendutse.

Inkinzo irashobora kugabanywamo ibice kandi bitandukanijwe.

Igice kimwe cya Shielding igifuniko gikosowe mubisanzwe cyitwa igice kimwe, mu buryo butaziguye SMT ifatanye na PCB, icyongereza muri rusange cyitwa Shielding Frame.

Inkinzo itandukanijwe ibice bibiri nayo ikunze kwitwa ingabo ebyiri, kandi inkinzo yibice bibiri irashobora gufungurwa bitabaye ibyo hifashishijwe igikoresho cyimbunda. Igiciro gihenze kuruta igice kimwe, SMT irasudwa kuri PCB, yitwa Shielding Frame, hejuru yavuzwe hejuru ya Shielding Cover, mu buryo butaziguye kuri Shielding Frame, byoroshye kuyisenya, mubisanzwe Ikadiri ikurikira yitwa ikingira ikingira, Igipfukisho cyavuzwe haruguru cyitwa igipfukisho. Ikadiri irasabwa gukoresha umuringa wera, amabati nibyiza; Igipfukisho kirashobora gukorwa muri tinplate, cyane cyane bihendutse. Ibice bibiri birashobora gukoreshwa mugice cyambere cyumushinga kugirango byorohereze gukemura, gutegereza ibyuma bikemura ibibazo, hanyuma utekereze gukoresha igice kimwe kugirango ugabanye ibiciro.
