Umuringaifite umuvuduko muke wa ogisijeni yo hejuru kandi irashobora guhuzwa nibintu bitandukanye bitandukanye, nk'icyuma, ibikoresho byangiza. Kandi umuringa wumuringa ukoreshwa cyane cyane mugukingira amashanyarazi na antistatike. Gushyira umuringa wumuringa hejuru yubutaka hanyuma ugahuzwa nicyuma cya substrate, bizatanga ubudahwema bwiza hamwe no gukingira amashanyarazi. Irashobora kugabanywamo: kwifata-umuringa wumuringa, uruhande rumwe rwumuringa wumuringa, impande ebyiri zumuringa hamwe nibindi bisa.

Muri iki gice, niba ugiye kwiga byinshi kubyerekeranye numuringa wumuringa murwego rwo gukora PCB, nyamuneka reba kandi usome ibiri hepfo muriki gice kugirango umenye ubumenyi bwumwuga.

Ni ibihe bintu biranga umuringa mu gukora PCB?

PCB y'umuringani intangiriro yumuringa ushyizwe kumurongo wimbere ninyuma yibibaho byinshi PCB. Uburemere bw'umuringa busobanurwa nk'uburemere (muri ounces) y'umuringa uboneka muri metero kare imwe y'ubuso. Iyi parameter yerekana ubunini rusange bwumuringa kurwego. MADPCB ikoresha uburemere bwumuringa bukurikira muguhimba PCB (pre-plate). Ibiro byapimwe muri oz / ft2. Uburemere bukwiye bw'umuringa burashobora gutoranywa kugirango buhuze ibisabwa.

· Mu gukora PCB, ifu yumuringa iri mumuzingo, urwego rwa elegitoronike rufite ubwiza bwa 99.7%, nubunini bwa 1 / 3oz / ft2 (12μm cyangwa 0.47mil) - 2oz / ft2 (70μm cyangwa 2.8mil).

· Umuringa wumuringa ufite umuvuduko muke wa ogisijeni wo hejuru kandi urashobora kubanza kwomekwa nabakora laminate kubikoresho bitandukanye, nkibikoresho byibyuma, polyimide, FR-4, PTFE na ceramic, kugirango bibyare laminate zambaye umuringa.

· Irashobora kandi kwinjizwa mubibaho byinshi nkumuringa ubwayo mbere yo gukanda.

· Mubikorwa bisanzwe bya PCB, umubyimba wanyuma wumuringa kumurongo wimbere usigara kumuringa wambere wumuringa; Kuruhande rwinyuma dushyira umuringa wongeyeho 18-30μm kumurongo mugihe cyo gutondeka ikibaho.

· Umuringa kumurongo winyuma wibibaho byinshi biri muburyo bwa fayili yumuringa hanyuma ugakanda hamwe na preregs cyangwa cores. Kugirango ukoreshe na microvias muri HDI PCB, ifu yumuringa iri kuri RCC (resin coated umuringa).

Kuki umuringa ukenewe mubikorwa bya PCB?

Icyuma cya elegitoroniki yumuringa (ubuziranenge burenga 99.7%, uburebure bwa 5um-105um) nikimwe mubikoresho byibanze byinganda za elegitoroniki Iterambere ryihuse ryinganda zamakuru ya elegitoronike, ikoreshwa ryumuringa wo mu rwego rwa elegitoronike riragenda ryiyongera, ibicuruzwa bikoreshwa cyane mu mibare yinganda, ibikoresho byitumanaho, ibikoresho bya QA, bateri ya lithium-ion, televiziyo ya gisivili, ibyuma bifata amashusho, abakinyi ba CD, kopi, terefone, icyuma gikonjesha, ibikoresho bya elegitoroniki, imashini zikoresha imikino.

Inganda z'umuringaIrashobora kugabanywamo ibyiciro bibiri: umuringa uzungurutswe (RA umuringa wumuringa) hamwe nuwumuringa wumuringa (ED umuringa wumuringa), aho kalendari yumuringa ya kalendari ifite ihindagurika ryiza nibindi biranga, nuburyo bwambere bwibisahani byoroshye byakoreshwaga kumuringa, mugihe amashanyarazi ya electrolytike ni igiciro gito cyo gukora umuringa wumuringa. Nkuko umuringa uzunguruka ari ikintu cyingenzi cyibikoresho byoroshye, niko ibiranga kalendari yumuringa hamwe nimpinduka yibiciro ku nganda zoroshye byoroshye bigira ingaruka runaka.

Ni ayahe mategeko shingiro yo gushushanya yumuringa muri PCB?

Wari uzi ko imbaho ​​zicapye zisanzwe zisanzwe mumatsinda ya electronics? Nzi neza ko umuntu ahari mubikoresho bya elegitoronike ukoresha nonaha. Ariko, gukoresha ibyo bikoresho bya elegitoronike utumva ikoranabuhanga ryabo nuburyo bwo gushushanya nabyo ni ibintu bisanzwe. Abantu bakoresha ibikoresho bya elegitoroniki buri saha imwe ariko ntibazi uko bakora. Hano rero hari ibice byingenzi bya PCB byavuzwe kugirango dusobanukirwe vuba nuburyo imbaho ​​zumuzingo zacapwe zikora.

· Ikibaho cyumuzingo cyacapwe ni ikibaho cyoroshye cya plastiki hiyongereyeho ikirahure. Umuringa wumuringa ukoreshwa mugukurikirana inzira kandi utuma urujya n'uruza rw'ibimenyetso n'ibikoresho biri mu gikoresho. Inzira z'umuringa nuburyo bwo gutanga ingufu mubice bitandukanye bigize ibikoresho byamashanyarazi. Aho kugirango insinga, ibimenyetso byumuringa biyobora urujya n'uruza muri PCBs.

· PCBs irashobora kuba urwego rumwe kandi ibice bibiri nabyo. PCB imwe igizwe nimwe yoroshye. Bafite umuringa utobora kuruhande rumwe naho urundi ni icyumba cyibindi bice. Mugihe kuri PCB igizwe na kabili, impande zombi zabitswe kubumba umuringa. Inshuro ebyiri ni PCB zigoye zifite ibimenyetso bigoye byo gutembera kwamafaranga. Nta mpapuro z'umuringa zishobora kwambuka. Izi PCB zirakenewe kubikoresho bya elegitoroniki biremereye.

· Hariho kandi ibice bibiri byabagurisha na silkscreen kuri PCB y'umuringa. Mask yo kugurisha ikoreshwa mugutandukanya ibara rya PCB. Hano hari amabara menshi ya PCB aboneka nkicyatsi, umutuku, umutuku, nibindi. Solder mask nayo igaragaza umuringa uva mubindi byuma kugirango wumve guhuza bigoye. Mugihe silkscreen nigice cyanditse cya PCB, inyuguti numubare bitandukanye byanditse kuri silkscreen kubakoresha na injeniyeri.

Nigute ushobora guhitamo ibikoresho bikwiye kumuringa muri PCB?

Nkuko byavuzwe mbere, ugomba kubona intambwe-ku-ntambwe yo gusobanukirwa uburyo bwo gukora ibibaho byacapwe. Ibihimbano byibi bibaho birimo ibice bitandukanye. Reka tubyumve hamwe nurukurikirane:

Substrate material:

Urufatiro rwibanze hejuru yikibaho cya plastiki gikoreshwa nikirahure ni substrate. Substrate nuburyo bwa dielectric yurupapuro rusanzwe rugizwe na epoxy resin hamwe nimpapuro. Substrate yakozwe muburyo ishobora kuzuza ibisabwa urugero ubushyuhe bwinzibacyuho (TG).

Intimba:

Nkuko bigaragara mwizina, lamination nuburyo bwo kubona ibintu bisabwa nko kwagura ubushyuhe, imbaraga zo gukata, nubushyuhe bwinzibacyuho (TG). Kumurika bikorwa munsi yumuvuduko mwinshi. Kumurika no gukuramo hamwe bigira uruhare runini mugutwara amashanyarazi muri PCB.
