ICT (Mubvunzo weMukati meDunhu): Mashandiro Ainoita, Mari Yayo, uye Kugadzira Mabhodhi Ayo

Yakagadziridzwa kekupedzisira: Chivabvu 2026 · Gwaro rinotarisa kugadzirwa kwekuyedzwa kwemukati medunhu

Bvunzo yemudunhu, kana kuti ICT, ndeimwe yemabasa ekugadzira zvemagetsi - kuongorora kwemagetsi nekukurumidza uye kwakakwana kunobata zvikanganiso zvekugadzirwa uye kuiswa kwekubatanidza. Asi ICT inoshanda zvakanaka chete kana bhodhi rakagadzirirwa iyo uye huwandu hwayo hunoratidza mutengo wayo wekutanga. Gwaro iri rinotsanangura zvinoitwa neICT chaizvo, mashandiro anoita chigadziko chembambo, zvinobatwa neICT uye zvayasiiwa, kuti inoenzaniswa sei neflying probe nedzimwe nzira dzekuyedza, hupfumi hunosarudza kuti ndeipi yekushandisa, uye mitemo yekugadzira bvunzo inoita kuti bhodhi rikwanise kuyedzwa pakutanga.

Chii chinonzi bvunzo yemudunhu (ICT)

Kuyedzwa kwemudunhu (in-circuit test) bvunzo yemagetsi yePCB yakaungana zvizere inoongorora chikamu chimwe nechimwe uye inoburitsa ruzivo rumwe chete. Pane kubvunza kuti "chigadzirwa chinoshanda here?" — ndiko kuyedzwa kunoshanda — ICT inosimbisa kuti chikamu chakakodzera chiri panzvimbo chaiyo, pamutengo wakakodzera, munzvimbo chaiyo, nechinhu chinosonesa ruzha.

Mubati wezvikanganiso zvemutsara

ICT ndiyo inobata zvikanganiso zvekugadzira. Inowana mapfupi, anovhurika, mavalue asina kunaka ezvikamu, uye zvikamu zvakadzoserwa shure - zvikanganiso zvinounzwa nekugadzirwa uye kugadzirwa, zvakasiyana nezvikanganiso zvekugadzira. Kana resistor iri kukosha kusina kunaka, capacitor isipo, diode iri kumashure, kana mambure maviri akabatanidzwa, ICT ndiyo danho rakagadzirirwa kuibata.

Nei zvichikodzera vhoriyamu

Nekuti ICT inogona kuongorora ma node akawanda panguva imwe chete, bvunzo yakazara inotora masekondi chete pabhodhi rega rega. Kumhanya ikoko ndiko kunoita kuti ICT ikwane magadzirirwo akagadzikana muhuwandu - kana chigadzirwa nepurogiramu zvavapo, bhodhi rega rega rinobuda pachena. Mutengo unonyanya kutaurwa pamusoro pechinhu, kwete panguva yebhodhi rega rega, izvo zvinoumba mamiriro ese emari ekushandisa.

Mashandiro anoita chipfeko chembambo

Chinonyanya kukosha muICT isimbi yekubata nzara : ndiro ine maturusi ine mapini akawanda kusvika kuzviuru ane mapini epogo, imwe neimwe yakaiswa kuti igare pabhodhi rekuyedza, kuburikidza, kana kuti neti yakafumurwa.

Makanika

Bhodhi rinodzvanywa pasi pachinhu chinobatika kuitira kuti pini yega yega ibatane panguva imwe chete. Muedzi anobva awana uye achiyera voltage, current, uye resistance pa node yega yega, achigadzira mufananidzo wakakwana wemagetsi webhodhi iri mukushanda kumwe chete. Nekuti kubatana kwese kunoitwa panguva imwe chete, chikamu chekuyera chinokurumidza zvikuru - kumhanya kwemasekondi pabhodhi kunotsanangura ICT kunobva zvakananga kubva pakubatana uku kwakafanana.

Kutarisa muganhu wemambure akavanzwa

Mabhodhi akakora ane maBGA ane mambure asingasvikwe neprobe chaiyo, nekuti maconnection acho akavigwa pasi pepakeji. Boundary scan (JTAG) inowedzera kufukidzwa kweICT kune maconnection edhijitari akavigwa nekushandisa test circuitry yakavakirwa mumachipisi pachayo — chip inoshuma pakubatana kwayo, saka hapana probe chaiyo inodiwa. Kubatanidza bed-of-nails probation ne boundary scan kunopa kufukidzwa kwakakura kunyangwe pamapuranga akazara, emazuva ano apo kuferefeta chete kwaizopotsa nzvimbo huru.

Zvinoonekwa neICT - uye zvainoshaya

Kuziva miganhu yeICT kwakakosha sekuziva simba rayo — inhanho imwe chete mukuyerera, kwete bvunzo yakazara pachayo.

Chii chakasimba paICT

ICT inobudirira pakubata mabhurugwa mapfupi uye inovhura pakati pemambure; ma resistors nema capacitors asipo, asina kunaka, kana kuti asina kushivirira; ma diode akadzoserwa kumashure, ma electrolytics, uye ma IC; mabhiriji ekusolder uye majoini asina kukwana; uye zvikamu zvisipo kana zvisiri izvo. Izvi ndizvo chaizvo zvikanganiso zvekugadzira zvisingaonekwe kana kuti izvo AOI isingakwanise kutonga nemagetsi.

Zvisingakwanise kuitwa neICT

ICT haigone kusimbisa kuti chigadzirwa chinoshanda zvechokwadi here — kutevedzana kwesimba, maitiro efirmware, mashandiro eRF, uye mashandiro emushandisi zvese zviri kunze kwenzvimbo yacho; ndiro basa rekuyedza kushanda. Uye ICT haigone kusvika kune mambure pasina mukana wekuwana probe, ndosaka mukana wekuyedza uchifanira kugadzirwa mubhodhi pane kuwedzerwa mushure mezvo. Mambure asina nzvimbo yekuyedza haaonekwe nepaburi rembambo.

Zvinoreva kushanda

Nekuti ICT inosimbisa kuvaka kwete mashandiro, mitsetse yekugadzira inoibatanidza nebvunzo inoshanda segedhi rekupedzisira. ICT inosimbisa kuti bhodhi rakavakwa nemazvo ; bvunzo inoshanda inosimbisa kuti rinoshanda . Zvose zvine basa, uye hapana chinotsiva chimwe.

ICT vs. flying probe vs. FCT vs. AOI vs. X-ray

Hapana nzira imwe chete inofukidza zvese, saka mitsetse yekugadzira inobatanidza zvakawanda. Tafura inoratidza kuti imwe neimwe yakakodzera.

Maitiro avanobatana mukuyerera kwakajairika

Nzira yakajairika inomhanya: AOI mushure mekudzokororwa kuti ionekwe nzvimbo inoonekwa uye zvikanganiso zve solder → X-ray yemajoini eBGA akavanzwa → ICT kana flying probe yekusimbisa magetsi → FCT segedhi rekupedzisira rinoshanda. Danho rega rega rinobata mhando yezvikanganiso izvo vamwe vasingakwanise, uye musanganiswa uyu unopa kufukidzwa kwakanyanya kupfuura chero nzira imwe chete.

ICT neflying probe ihama

ICT neflying probe zvinoita zvakafanana pakuongorora magetsi; musiyano uripo ndewemakanika. ICT inobata poindi imwe neimwe panguva imwe chete kuburikidza nechinhu chimwe chete; flying probe inofambisa maprobe mashoma kubva panzvimbo imwe kuenda kune imwe zvakatevedzana. Musiyano iwoyo mumwe chete unotungamira mutengo wese uye kukurumidza kutengeserana pakati pawo.

Zvehupfumi: kana ICT ichikosha

Kushandiswa kweICT kunodhura zvakanyanya , uye kunzwisisa izvozvo ndiko kunokosha pakusarudza kana wozoishandisa zvachose.

Mari yekugadzirwa kwezvinhu

Chishandiso chembambo chakagadzirwa nemaoko chinotengeswa kamwe chete — kazhinji chinowanzova mazana mashoma kusvika zviuru zvemadhora ekuAmerica zvichienderana nehuwandu hwemapini uye kuoma kwacho — pamwe nemari yekunyora nekugadzirisa chirongwa chekuyedza. Kana izvozvo zvabhadharwa, bhodhi rega rega rinoedza mumasekonzi, saka mutengo webhodhi rega rega unodzikira zvishoma nezvishoma sezvo vhoriyamu ichikwira. Vhoriyamu yakawanda inopararira mutengo wechinhu; vhoriyamu yakaderera haigone.

Kutengeserana kweFlying-Probe

Chinobhururuka hachidi chinhu — mapurobe anotenderera panzvimbo imwe — asi chinotora maminetsi pabhodhi pane masekondi. Kutenderera kunofamba mumasekonzi makumi matatu paICT kunogona kutora nguva yakareba papurobe inobhururuka. Saka chinobhururuka chinokunda pavhoriyamu shoma (hapana chinhu chekubhadhara kana kurasa) uye chinorasikirwa nevhoriyamu yakawanda (inononoka pabhodhi), inova ndiyo mufananidzo weICT.

Mutemo wesarudzo

• Maprototypes, vhoriyamu yakaderera, kana dhizaini ichiri kuchinja → flying probe: hapana chinhu chekubvisa kana marongerwo acho achinja.
• Magadzirirwo akura, akaomeswa nechando ane huwandu hwepakati kusvika hwepamusoro → ICT: mutambo unobhadhara wega mukati menguva yakatarwa.

Yambiro yakakodzera kuteererwa: kuchinja marongerwo echinhu kunogona kumanikidza kuti chinhu chivakwezve, saka simbisa dhizaini yacho wobva wasimbisa nzvimbo dzekuyedza usati wazvipira kuchinhu cheICT. Kuvaka chinhu chekugadzira chinozochinja kunotambisa mari yese yaunodyara.

Kugadzira ICT: mitemo inokosha

Kupinda mubvunzo kunofanirwa kurongwa usati wamiswa — kuigadzirisa gare gare kunodhura kana kuti hazvigoneke. Mitemo iyi yekugadzira-ye-bvunzo (DFT) inoita kuti bhodhi rigadzirire ICT.

Mitemo yepoinzi yekuyedza

• Tipei nzvimbo imwe chete yekuyedza yakatsaurirwa panet chero pazvinogoneka — mambure asina poindi yekuyedza haagone kuferefetwa.
• Gadzira ma test pads 1 mm (35–40 mil) dhayamita; usambofa wakaderera pane yakatarwa neimba yako yekugadzira.
• Isa mapedhi pane Giridhi remamirimita zana (2.54 mm) kana zvichibvira kuti zvikwane maturusi akajairwa.

Mitemo yekubvisa uye yekuisa

• Chengeta zvishoma 0.5 mm kureba kubva pamucheto wega wega wepedhi kusvika kumhangura kana zvikamu zviri pedyo.
• Isa ma test pads rimwe divi yebhodhi (kazhinji iri pasi) saka inogara pasi pachigadziko.
• Chengeta mapedhi ari kure nemupendero webhodhi uye kure nezvinhu zvirefu; usamboisa pedhi apo chikamu chinovhara nzira yeprobe.
• wedzera maburi ekushandisa uye mafiducials saka chinhu chacho chinogadzirisa bhodhi nemazvo.

Sei mitemo iyi ichibatsira?

Mutemo wega wega uripo wekuona kuti probe inogona kusvika uye kubata mambure ese nenzira yakavimbika. Kuderedza nzvimbo dzekuyedza uye kufukidza kunodonha; kuungana kwemapedhi uye maprobe anopotsa; kanganwa kuti fiducials uye alignment inokanganisika. Kugadzira bvunzo kubva pakutanga hakudhuri zvakanyanya; kuwedzera izvozvo gare gare kunogona kureva respin.

Zvekutumira mugadziri wako kune ICT

Kugadzika kweICT kunoda zvinopfuura mafaira ekugadzira - chirongwa chekuyedza chakavakwa kubva padata rekugadzira rinoratidza node yega yega uye kukosha kwayo kunotarisirwa.

Sei ruzivo rwakakwana ruchidzivirira kunonoka

Chirongwa chekuyedza chinogona kungotarisa zvinotsanangurwa netlist neBOM. Data risina kukwana kana kuti risina kuenderana zvinoreva kuti chirongwa ichi chakavakirwa pakufungidzira, izvo zvinoonekwa sekukundikana kwenhema kana zvikanganiso zvisina kurongeka. Kutumira pasuru yakazara, yakadzokororwa-yakafanana kunoita kuti mainjiniya wekuyedza agadzire chirongwa chinoratidza bhodhi raunoda kuti rigadzirwe.

Mashandisirwo anoitwa Highleap muICT

Highleap Electronics inoongorora nzira yekupinda nayo panguva yeDFM uye inoongorora mambure pasina nzvimbo yekuvheneka usati wagadzira chinhu, inopa mazano paICT vs. flying probe zvichienderana nehuwandu hwako uye kuti dhizaini yacho ingachinja kangani, uye inosanganisa ICT neAOI, X-ray, FCT, uye programming uko chigadzirwa chinoda - nemagwaro ekuyedza kuti aonekwe kana zvakumbirwa. Kubata nzvimbo yekuyedza isipo panguva yekuongorora kweDFM kwemahara kwakachipa pane kuiwana mushure mekunge chinhu chachekwa. Ona masevhisi edu ePCB assembly.
