I-Copper FoilInesilinganiso esiphansi se-oxygen engaphezulu futhi inganamathiselwa ngezinhlobonhlobo ezahlukahlukene ezahlukahlukene, njengezinsimbi zensimbi, izinto ezifaka i-infal. Futhi i-foil ye-Copper isetshenziswa kakhulu ekuvikeleni i-electromagnetic kanye ne-antistatic. Ukubeka i-foil ye-copper esebenzayo endaweni engaphansi komhlaba futhi kuhlanganiswe ne-substrate yensimbi, kuzohlinzeka ngokuqhubeka okuhle nokuvikelwa kwe-electromagnetic. Ingahlukaniswa i-Foil ye-Fopper ye-Folip-anamathela, i-foil ye-solip eyodwa, i-foil ephindwe kabili yethuli kanye nokunye.

Kule ndima, uma uzofunda kabanzi nge-Foil Foil kwinqubo yokukhiqiza ye-PCB, sicela ubheke futhi ufunde okuqukethwe okungezansi kule ndima ngolwazi oluningi lochwepheshe.

Yiziphi izici ze-foil yethusi ekukhiqizeni i-PCB?

I-PCB Copper FoilUkuqina kwe-Copper kokuqala okusetshenziselwa izingqimba zangaphandle nezangaphakathi zebhodi le-PCB ye-Multilayer PCB. Isisindo se-Copper sichazwa njengesisindo (emaphaketheni) se-Copper esikhona endaweni eyodwa yezikwele. Le pharamitha ibonisa ubukhulu bethusi engxenyeni. I-MadPCB isebenzisa izinsimbi zethusi ezilandelayo ze-PCB Facrication (Pre-Plate). Izinsimbi zilinganiswe ku-OZ / FT2. Isisindo sethusi esifanele singakhethwa ukuze silingane nesidingo sokuklama.

Ezokukhiqiza i-PCB, ama-foils ethusi ase-rolls, okuyibanga le-elekthronikhi elinobumsulwa be-99.7%, nobukhulu be-1 / 35MM noma i-0.47mil) - 2oz / FT2 (70μm).

· I-foil ye-Copper inezinga eliphansi le-oxygen engaphezulu futhi ingahle ifakwe kuma-laminate abakhiqizi ezintweni ezahlukahlukene zezinto, njengezinto zensimbi, i-ptfe, i-ceramic, ukukhiqiza ama-cherper amalambu.

· Futhi ingethulwa ebhodini le-multilayer njenge-foil yethuli ngaphambi kokucindezela.

Ukukhiqiza okujwayelekile kwe-PCB, ubukhulu bokugcina bethusi ezingqimba zangaphakathi buhlala buhlalu be-foil ye-Copper; Ezingxenyeni zangaphandle sisebenzisa ithusi elengeziwe le-18-30μM kumathrekhi ngesikhathi senqubo yephaneli yokuqothula.

· I-Copper yezendlalelo zangaphandle zamabhodi we-multilayer isesimweni se-foil yethusi futhi icindezelwe kanyekanye noma ama-cores. Ukuze usebenzise nge-microvias ku-HDI PCB, i-foil yethusi ngqo ku-RCC (Resin Coice Copper).

Kungani i-foil yethuli iyadingeka ekukhiqizeni kwe-PCB?

I-foil ye-elekthronikhi ye-elekthronikhi (ubumsulwa be-99.7%, ubukhulu be-5Um-105um) kungenye yezinto eziyisisekelo zezinkampani ze-elekthronikhi, ukusetshenziswa kwe-lithium-ion, amasheya we-lithium, amasethi we-chithium, amasheya we-chithium, amasheya we-cd, ocingweni, izingcingo, zocingo, umoya Isimo, ama-elekthronikhi wezimoto, iziduduzo zomdlalo.

I-Foil Yethusi YezimboniIngahlukaniswa izigaba ezimbili: I-Font Foil Foil (RA Copper Foil) kanye ne-Point Foil Foil), lapho i-foil ye-computer yekhalenda inezindleko zethusi zokukhiqiza i-foil ye-Copper. Njengoba i-foil ye-rolling yethusi iwukubonakalayo okubalulekile kwebhodi elithambile, ngakho-ke izici zekhalenda le-foil foil kanye nezinguquko zentengo embonini yebhodi elithambile zinomthelela othile.

Yimiphi imithetho eyisisekelo yemithetho ye-Folip Foil ku-PCB?

Uyazi ukuthi amabhodi wesifunda aphrintiwe ajwayelekile kakhulu eqenjini le-elekthronikhi? Nginesiqiniseko esihle impela esikhona kudivayisi ye-elektroniki oyisebenzisayo manje. Kodwa-ke, usebenzisa la madivayisi kagesi ngaphandle kokuqonda ubuchwepheshe babo kanye nendlela yokuklama nakho kuyindlela ejwayelekile. Abantu basebenzisa amadivaysi kagesi njalo ngehora elilodwa kodwa awazi ukuthi basebenza kanjani. Ngakho-ke nazi ezinye izingxenye eziphambili ze-PCB ezishiwo ukuthi zinokuqonda okusheshayo kwamabhodi wesifunda aphrintiwe.

· Ibhodi yesekethe ephrintiwe ngamabhodi epulasitiki alula ngokufakwa kwengilazi. I-Foil Foil isetshenziselwa ukulandelela izindlela futhi ivumela ukugeleza kwamacala kanye namasiginali ngaphakathi kwedivayisi. Imicerasi yethusi yindlela yokuhlinzeka ngamandla ezingxenyeni ezihlukile zedivayisi kagesi. Esikhundleni sezintambo, umkhondo wethusi umhlahlandlela wokugeleza kwamacala kuma-PCB.

· PCBS kungaba ungqimba olulodwa nezingqimba ezimbili futhi. I-PCB eyodwa ebekwe yiyona elula. Bane-topper topop ohlangothini olulodwa futhi ngakolunye uhlangothi kukhona indawo yezinye izinto. Ngenkathi ku-PCB ebekelwe kabili, zombili izinhlangothi zigcinelwe ukugcwala kwethusi. Kubuyiselwe kabili ama-PCB ayinkimbinkimbi anemibala eyinkimbinkimbi yokugeleza kwamacala. Ayikho ama-foils ethusi angawela omunye komunye. Lawa ma-PCB ayadingeka kumadivayisi ashubile kagesi.

Kukhona futhi izingqimba ezimbili zamasosha kanye nesilika ku-PCPB PCB. Imaski yomthengisi isetshenziselwa ukwahlukanisa umbala we-PCB. Kunemibala eminingi ye-PCBS etholakala njengeGreen, onsomi, ebomvu, njll. I-Solder Mask futhi icacisa ithusi kwezinye izinsimbi ukuqonda ubunzima bokuxhuma. Ngenkathi i-Silkscreen yingxenye yombhalo ye-PCB, izinhlamvu ezahlukahlukene nezinombolo zibhalwe ku-silkscreen yomsebenzisi kanye nonjiniyela.

Ungayikhetha kanjani kahle impahla ye-Folip Foil ku-PCB?

Njengoba kushiwo ngaphambili, udinga ukubona indlela yesinyathelo ngesinyathelo sokuqonda iphethini yokukhiqiza yebhodi yesekethe ephrintiwe. Ukuqanjwa kwalawa mabhodi aqukethe izingqimba ezihlukile. Ake siqonde lokhu ngokulandelana:

Impahla engezansi:

Isisekelo sesisekelo phezu kwebhodi lepulasitiki eliqiniswe ngengilazi yi-substrate. I-substrate yisakhiwo se-dielectric seshidi evame ukwenziwa ngama-epoxy resins nephepha lengilazi. I-substrate yakhelwe ngendlela yokuthi ingahlangabezana nesidingo sokwenza izinga lokushisa lokushintsha (TG).

Isigqi:

Kucace bha kusuka egameni, ukugqama nakho kuyindlela yokuthola izakhiwo ezidingekayo njengokunwetshwa kwe-thermal, amandla okugunda, nokushisa (TG). Ukumangala kwenziwa ngaphansi kwengcindezi ephezulu. Ukubuyiselwa kanye Nokuxhashazwa Ndawonye dlala indima ebalulekile ekuhambeni kwamacala kagesi kwi-PCB.
