Ibura ry'ibikoresho bya elegitoronike no kuzamuka kw'ibiciro. Itanga amahirwe kubiganano.
Muri iki gihe, ibikoresho bya elegitoroniki byiganano bigenda byamamara. Impimbano nyinshi nka capacator, résistoriste, inductors, tebo ya MOS, na mudasobwa imwe ya chip irazenguruka ku isoko. Usibye kubona abakozi basanzwe bagura byinshi bishoboka, injeniyeri nabaguzi bagomba guhanga amaso bakiga kumenya ibinyoma!
Ariko, niba ushaka gutandukanya ibice bya elegitoroniki byukuri kandi byimpimbano, ugomba kubanza kumva itandukaniro riri hagati yumwimerere nishya.
1. Niki gicuruzwa gishya cyumwimerere?
Ibicuruzwa bishya byumwimerere nijambo ryumwimerere ryuruganda rwumwimerere, gupakira umwimerere, LABLE yumwimerere (icyitegererezo cyuzuye, nimero yicyiciro, ikirango, nimero NYINSHI (IC gupakira inteko hamwe na kode yimashini yakoreshejwe), ingano yububiko, kode (irashobora kuba Reba kurubuga rwayo), barcode (mubisanzwe kuri anti-mpimbano).
Ibipimo byose byujujwe nuwabikoze, harimo ibicuruzwa byumwimerere. Ubwiza bwibicuruzwa nibyiza cyane, umubare wicyiciro ni kimwe, kandi isura ni nziza. Abakiriya bafite ubushake bwo kubyemera, ariko igiciro kiri hejuru.
Igicuruzwa cyumwimerere nigicuruzwa cyapakiwe muburyo butaziguye kuva muruganda rwambere. Igipapuro cyumwimerere gishobora kuba cyarafunguwe cyangwa nta paki yumwimerere ihari, ariko iracyari ibicuruzwa byumwimerere.
Shoddy bulk nshya (ni ukuvuga ibicuruzwa bifite inenge)
Sub-chips ni chipi zavanyweho kumurongo winteko ya IC kubera ubwiza bwimbere nibindi bibazo, ariko ntibyatsinze ikizamini cyabashushanyo. Cyangwa kubera gupakira bidakwiye, isura ya firime yangiritse, kandi chip nayo iravaho.
● Filime ziva kumurongo. Ni firime yakuweho mugihe cyo kugenzura nuwabikoze. Izo firime ntabwo zasobanuye ko hagomba kubaho ibibazo bifite ireme, ariko ko ibipimo bimwe byari bifite amakosa manini ugereranije.
Kuberako abakora ibicuruzwa akenshi basabwa cyane kugirango firime ibe yuzuye, nka voltage nubu, kandi ikosa ryemewe rishobora kuba riri muri plus cyangwa gukuramo 0.01, noneho mugihe firime isanzwe igomba kuba 1.00, 1.01 na 0.99 byose nibicuruzwa nyabyo, na 0.98 cyangwa 1.02 nigicuruzwa gifite inenge.
Izi firime zatoranijwe hanyuma zitwa firime nshya. Mu buryo nk'ubwo, kubera gucika intege kwa firime, firime ishaje irashobora gutera impinduka nto muburyo bwa parameter mugihe cyo gutunganya. Iyi niyo mpamvu rimwe na rimwe ibicuruzwa bimwe, abakiriya bamwe barabikoresha, nabakiriya bamwe barabikoresha. .
● Muburyo bwo kugenzura ubuziranenge, kubera ko umurongo winteko unyura kuri mudasobwa mugihe cyo kugenzura wongeyeho intoki za mudasobwa, rimwe na rimwe firime ntabwo iba ari ikibazo rwose, ariko iyo ifatanye, abakozi bahitamo kwica igihumbi kubeshya kuruta kurekura. Nyuma ya firime mbi, nuko uhomba byinshi, noneho ibi byitwa gushya gushya.
2. Imizigo mishya ni iki?
Sanxin irashobora kugabanywa mubihe bikurikira ukurikije uko isoko ryifashe:
★ Muburyo nyabwo bwubwinshi (nukuvuga ibicuruzwa byumwimerere bidafite ipaki yumwimerere)
Customer Icyifuzo cyabakiriya kiri munsi yububiko bwose. Bitewe nigiciro cyibiciro, utanga isoko asenya paki yumwimerere yose hanyuma agurisha igice cya chip ku giciro cyo hejuru, naho igice gisigaye cya chip nta paki yambere.
● Kubera impamvu zubwikorezi, utanga ibicuruzwa asenya ibicuruzwa byapakiwe mbere kugirango byoroherezwe gutwara. Ibicuruzwa byumwimerere nka Hong Kong bigomba koherezwa i Shenzhen nahandi. Kugirango winjire muri gasutamo no kugabanya ibiciro, ibipapuro byumwimerere bivanwaho kandi abantu benshi bajyanwa muri gasutamo.
Products Ibicuruzwa bishya kandi bishaje: Ibyinshi muri ibyo bicuruzwa nibyo byabitswe igihe kirekire kandi bifite isura mbi. Birashobora gukoreshwa gusa kubijugunya byinshi.
● Hariho n'inganda zimwe zipakira. Iyo umubare munini wa waferi woherejwe mu ruganda rupakira gupakira, nyuma yo kurangiza ishami rishinzwe igishushanyo mbonera cya IC ntirishobora kwakira waferi zose zapakiwe kubera ibibazo byamafaranga, noneho iki gice cyuruganda rutunganya ibicuruzwa ruzagurisha wenyine. , kuberako bidakenewe Bakeneye gushyira akamenyetso kabo kandi ntibazakora ibipfunyika kugirango bongere ibiciro, bityo bazabigurisha kubwinshi.
● Kubera ibibazo byubuyobozi bwuruganda rupakira, firime abakozi bayo bakuye hanze yikigo binyuze mumiyoboro idasanzwe, kugurisha no kugura firime, byinjira mugihugu. Ubu bwoko bwa firime ntabwo ipakira hanze kuko ntaburyo bwo gupakira bwa nyuma, ariko igiciro ni cyiza kandi rimwe na rimwe kikaba cyiza kuruta igiciro cyikigo cyigihugu.
Ubwinshi bwibinyoma (ni ukuvuga ibicuruzwa byavuguruwe)
Ibicuruzwa byavuguruwe biravugururwa cyangwa ibice byashenywe. Bitunganijwe kandi bigasubirwamo ibice, abantu rero muruganda mubisanzwe babita ibicuruzwa byavuguruwe.
Ibigaragara bimwe byangiritse, ariko ibyangiritse hejuru ntabwo bikomeye cyane, kandi firime zigoye gutunganya zirashobora kugurishwa nka firime nshya nyuma yo kuvugururwa.
● Witondere film zo mu gisekuru cya kabiri zifite isura nziza. Amafilime nkaya arashobora kuba sub-firime ifite ibibazo byimbere. Abagura firime nkizi muri rusange baritonda.
Kuvugurura firime zishaje ahanini binyuze mugusubiramo firime zishaje, nko gusya, gukaraba, gukurura ibirenge, gutera ibirenge, guhuza ibirenge, gusya inyuguti, kwandika, nibindi. Kugaragara kwa firime gutunganywa kugirango film igaragare neza.
Ahanini imyanda yo mumahanga, ni ukuvuga ibikoresho byo murugo byo hanze, mudasobwa, router nibindi bikoresho byamashanyarazi bishaje bitunganyirizwa ahakusanyirizwa imyanda. Iyi myanda ijyanwa mu turere twa Hong Kong, Guangdong, Tayiwani, Zhejiang, na Chaoshan kugira ngo itunganyirizwe ku giciro gito cyane.
Kuvugurura inyuguti zumwimerere nugutunganya gusa isura ya firime kugirango film igaragare neza. Ubu bwoko bwibicuruzwa bifite ubuziranenge kandi buhendutse, muri rusange kimwe cya kabiri cyigiciro cyiza cyangwa gihendutse.
Goods Ibicuruzwa byakoreshejwe, gusenya ibice. Ibicuruzwa byarakoreshejwe, kandi bivanwa ku kibaho cyumuzunguruko n'umwuka ushushe cyangwa gukaranga. Uburyo bubiri bwo gusenya firime zishaje:
Uburyo bushyushye bwo mu kirere, ubu buryo nuburyo busanzwe, bukoreshwa ku mbaho zisukuye kandi zifite isuku, cyane cyane imbaho za SMD zifite agaciro.
Uburyo bwa "Frying", ibi nukuri. Koresha amavuta yubutare atetse cyane "gukaranga". Ikibaho cyimyanda ishaje cyane cyangwa yuzuye imyanda mubisanzwe ikoresha ubu buryo.
Imyanda ikorwa mugikorwa cyo gutandukanya no kongera gukora firime ishaje izanduza cyane ibidukikije niba idafashwe neza, kandi ikiguzi cyo "kujugunya neza" kizaba kinini kuruta amafaranga yinjiza yose.
Kubwibyo, ibigo bimwe mubihugu byateye imbere byahitamo gukoresha amafaranga no kohereza ibicuruzwa "kohereza" e-imyanda mubushinwa ndetse no mubihugu bimwe na bimwe byo muri Aziya yepfo kuruta kubijugunya ubwabyo. Itandukaniro ryibiciro hagati ya chip na kera ni kure yo kugarura igihombo cyangiza ibidukikije!
Ubucuruzi bwinshi ku isoko rya elegitoroniki bukunze gusobanura ibicuruzwa byavuguruwe nkibicuruzwa byinshi bishya, bisaba guhumura amaso no kwishingikiriza kubuhanga buto bwo kubitandukanya.
3. Itandukaniro riri hagati yibicuruzwa byinshi nibicuruzwa byavuguruwe
Ubwiza bwibicuruzwa byinshi birashobora kwizezwa.
Ibicuruzwa bifite inenge bizaba bitandukanye nibicuruzwa byumwimerere ukurikije igipimo cyakuweho kandi gihamye. Kuberako ubu bwoko bubiri bwibicuruzwa ari shyashya, biragoye cyane kubutandukanya.
Ibicuruzwa byavuguruwe biranangiza cyane. Irashobora kugurisha inyama zimbwa. Barasa, ariko mubyukuri, bafite imirimo itandukanye rwose.
Kubwibyo, nibyiza kuri wewe kwirinda ibicuruzwa byinshi, keretse uguze ukurikije garanti zimwe.
