Umuringaifite umubare muto wa ogisijeni yubuso kandi irashobora kwifatamo ibice bitandukanye, nkicyuma, ibikoresho. N'umuringa w'umuringa ukoreshwa ahanini mu ngabo ya electomagnetic na antistatike. Gushyira umuringa wumuringa uyobora substrate kandi uhujwe na substrate yicyuma, bizatanga ubudahwema no gukingira electoragnetic. Irashobora kugabanywamo: kwifata umuringa umuringa, uruhande rumwe rwumuringa, ibirindiro bibiri by'umuringa by'umuringa nibindi nkibyo.

Muri iki gice, niba ugiye kwiga byinshi kubyerekeye umuyoboro wumuringa mubikorwa bya PCB, nyamuneka reba kandi usome ibirimo hepfo muri iki gice kugirango ubumenyi bwinshi bwumwuga.

Ni ibihe bintu biranga umuringa mu nganda ya PCB?

PCB UmuringaEse umurinzi wambere wumuringa wakoreshejwe kumurongo wo hanze kandi wimbere winama yumubare wa pcB. Uburemere bw'umuringa busobanurwa nkuburemere (muri ounci) bwumuringa uhari muri metero kare. Iyi parameter yerekana ubunini bwumuringa kumurongo. Madpcb ikoresha uburemere bwumuringa ibikurikira kugirango ibihimbano bya PCB (Pre-plate). Ibipimo byapimwe muri OZ / FT2. Uburemere bwumuringa bukwiye burashobora gutorwa guhuza ibishushanyo mbonera.

· In PCB manufacturing, the copper foils are in rolls, which are electronic grade with purity of 99.7%, and thickness of 1/3oz/ft2 (12μm or 0.47mil) – 2oz/ft2 (70μm or 2.8mil).

· Copper fiil ifite igipimo cyo hasi ogisijeni cyo hejuru kandi irashobora kubanziriza abakora laminate mubikoresho bitandukanye byibanze, nkicyuma, ftfe na ptfe na cemic, kugirango babone laminates.

Kandi harashobora kandi gutangizwa mu kibaho mu mibereho myinshi nk'umuringa ubwayo mbere yo gukanda.

· Mubikorwa bisanzwe bya PCB, umubyimba wanyuma wumuringa kubisigazwa byimbere bisigaye umuringa wambere; Mu bice byo hanze twirukanye 18-30μm umuringa ku rutonde mugihe cyo gukora akanama.

· Umuringa wo hanze yintebe Multilayer ari muburyo bwumuringa kandi ukandagira hamwe na offict offt cyangwa cores. Kugirango ukoreshe microvias muri HDI PCB, umuringa uri kuri RCC (resin yahitanye umuringa).

Kuki umuringa wumuringa ukenewe mugikorwa cya PCB?

Icyiciro cya elegitoroniki icyiciro cya chaprer (cyera kirenze 99.7%, umubyimba 5- 105um) ni kimwe mubikoresho bya elegitoroniki iterambere ryibibazo byihuta byiterambere ryibibazo byinganda ziterambere ryibibazo byinganda ziterambere ryibibazo byinganda ziterambere ryihuse. Amakopi, terefone, ikonjesha, ibikoresho bya elegitoroniki, iy'amashanyarazi.

Umuringa wingandaIrashobora kugabanywa mu byiciro bibiri: kuzunguruka umuringa (ra umuringa) na point fiil foil fomp, aho ifumbire ya electrolytique yakoresheje umuringa, mugihe ibiranga umuringa byoroheje ni ikiguzi gito cyo gukora umuringa. Nkuko umuringa wumuringa ufite ibikoresho byingenzi byinama yoroshye, niko ibintu biranga umuringa by'umuringa hamwe nibiciro byibiciro ku nganda zoroshye.

Ni ubuhe butumwa bw'ibanze bwo gushushanya umuringa muri PCB?

Waba uzi ko imbaho ​​z'umuriro zisanzwe zikunze kugaragara mu itsinda rya elegitoroniki? Nzi neza ko umuntu aboneka mubikoresho bya elegitoroniki ukoresha nonaha. Ariko, ukoresheje ibi bikoresho bya elegitoroniki utumva ikoranabuhanga ryabo nuburyo bwo gutegura nabyo nibyiciro rusange. Abantu bakoresha ibikoresho bya elegitoroniki buri saha imwe ariko ntibazi uko bakora. Hano rero hari ibice byingenzi bya PCB bivugwa kugirango usobanukirwe byihuse uburyo imbaho ​​zizunguruka zikora.

· Ikibaho cy'umuriro ucapwe ni imbaho ​​mbi zoroshye zongeyeho ikirahure. Umuringa wa file ukoreshwa mugukurikirana inzira kandi yemerera ibirego n'ibimenyetso mubikoresho. Ibimenyetso by'umuringa nuburyo bwo gutanga imbaraga kubice bitandukanye byibikoresho byamashanyarazi. Aho insinga, ibimenyetso by'umuringa biyobora ibirego by'ibyaha muri PCB.

· PCB irashobora kuba igice kimwe n'ibice bibiri. PCI imwe yashyizwemo nizo zoroshye. Bafite umuringa ku ruhande rumwe n'urundi ruhande nicyumba cyibindi bice. Mugihe kuri PCB ebyiri, impande zombi zibitswe kumuringa. Ibice bibiri nicbs igoye ifite ibimenyetso bigoye kugirango biregure. Nta muringa wumuringa urashobora kwambuka. Izi PCB zirasabwa kubikoresho biremereye bya elegitoroniki.

· Harimo kandi ibice bibiri byagurishijwe na silkscreen ku muringa PCB. Mask yumugurisha ikoreshwa mugutandukanya ibara rya PCB. Hano hari amabara menshi ya PCB iboneka nkicyatsi kibisi, umutuku, umutuku, nibindi. Mugihe icyatsi kibisi igice cya PCB, inyuguti zitandukanye nimibare byandikwa kuri silksien kubakoresha na injeniyeri.

Nigute wahitamo ibikwiye ibikoresho kumuringa muri PCB?

Nkuko byavuzwe mbere, ugomba kubona uburyo bwintambwe ya-kuntambwe yo kumva uburyo bwo gukora bwinama yumuriro wacapwe. Ibihimbano by'ibi bibaho birimo ibice bitandukanye. Reka tubyumve hamwe nurukurikirane:

Ibikoresho byongereranyo:

Fondasiyo shingiro hejuru yinama ya plastiki yubahiriza ikirahure ni substrate. Intsinzi nimiterere yimirire yurupapuro mubisanzwe igizwe na epoxy resions nimpapuro. Intsinzi irateguwe muburyo bushobora kuzuza ibisabwa kurugero rwubushyuhe bwinzibacyuho (TG).

Kubura:

Nkuko bigaragara mwizina, amatara nuburyo bwo kubona ibintu bisabwa nkisuku ryubushyuhe, imbaraga zo guswera, imbaraga zo guswera, hamwe nubushyuhe bwinzibacyuho (tg). Kugerageza bikorwa munsi yigitutu kinini. Kubura no kwerekana hamwe bigira uruhare runini mugutera amashanyarazi muri PCB.
