In-Circuit Testing (ICT): Inobatsira Iwe Kugadzira Yepamusoro-mhando PCB

Kuedza kwemukati medunhu (ICT) inzira inoshandiswa zvakanyanya mukugadzira maelektroniki yePCBA yekusimbisa kukosha kwezvikamu uye kubatana kwemagetsi pabhodhi redunhu rakadhindwa rakaunganidzwa. ICT inoitwa mushure mekunge zvikamu zvaiswa uye zvasungirirwa, inobatsira kuona matambudziko akajairika ekubatanidza - akadai sekuvhurwa , mapfupi, zvikamu zvisipo, zvikamu zvisirizvo , uye zvikanganiso zvine chekuita nekubatanidza zvine chekuita nesolder - chigadzirwa chisati chaenda kumatanho ekupedzisira senge kuyedzwa kwebasa kana kubatanidzwa kwekupedzisira.

Kuedzwa kweMukati meDunhu (ICT) kwePCB Assembly (PCBA)

Mukubatanidza PCB, ICT inowanzoitwa uchishandisa chinhu chakatsaurirwa (kazhinji chinhu chinonzi "mubhedha wezvipikiri") chinosangana nenzvimbo dzakatarwa dzekuyedza paPCBA. Muyedzisi anoshandisa uye anoyera masaini emagetsi pamanode aya kusimbisa kuti mambure nezvikamu zvinoshanda sezvaitarisirwa zvichienderana nechirongwa chekuyedza.

Munguva yeICT, maprobe anopinda munzvimbo dzekuyedza dzePCBA kuti aone maparamita emagetsi akadai sekuenderera mberi, kupatsanurwa, kuramba, uye (kana zvichibvira) kutarisa zvine chekuita nemagetsi. Izvi zvinobvumira vagadziri kuongorora mabhodhi kuti vaone kana paine zvikanganiso pakusangana, kuderedza kugadziriswa patsva mukugadzirwa, uye kuvandudza goho rose uye kugara kwenguva refu.

Zvikanganiso zvinowanzoonekwa neICT zvinosanganisira macircuit akavhurika, macircuit mapfupi, zvikamu zvisiri izvo kana zvisipo, zvikanganiso zve polarity/orientation, uye matambudziko ekubatana anokonzerwa nekukanganisa kwekusonesa kana ma trace akakuvara. Nekubata matambudziko aya padanho rePCBA, ICT inobatsira kuona kuti ma assemblies anopinda mumatanho ekugadzira anotevera anosangana nezvinodiwa zvemagetsi uye anotsigira zvigadzirwa zvekupedzisira zvakavimbika.

Nei In-Circuit Testing Yakakosha kuPCB Gungano

Iyo PCB gungano rekuita rinosanganisira zvinhu zvakawanda, uye kuve nechokwadi chekuti chimwe nechimwe chazvo chinoshanda sezvakatarisirwa kwakakosha pakuita kwechigadzirwa chekupedzisira. Ichi ndicho chikonzero In-Circuit Testing yakakosha kuPCB gungano:

• Kuedzwa kweComponent-Level : ICT inoita kuti chikamu chimwe nechimwe chiri paPCB assembly chishande sezvaitarisirwa. Inoedza zvikamu zvakaita se resistors, capacitors, integrated circuits (ICs), uye connectors kuti ione kana chimwe nechimwe chinosangana nemagetsi akatarwa.

• Inodzivirira Kukundikana Kwebasa : ICT inoona matambudziko akadai sekukanganisa kuiswa kana kusarongeka kwezvikamu, ichiva nechokwadi chekuti kubatanidzwa kunoshanda nemazvo isati yaenderera mberi mukugadzirwa.

• Kuona Matambudziko Ekunyungudutsa : Kuongororwa kwemukati medunhu kunogona kuona zvikanganiso zvekunyungudutsa zvakaita semajoini anotonhora, mabhiriji ekunyungudutsa, kana mapini asina kubatana, zvichidzivirira kutadza kushanda kwechigadzirwa chekupedzisira.

• Kuderedza Mari Pakugadzirisa : Nekuona zvikanganiso nekukurumidza, ICT inoderedza kudiwa kwekugadzirisa zvakare. Kana paine zvikanganiso zvakaonekwa, zvinogona kugadziriswa usati watanga kuunganidza zvinhu kusvika pakuedzwa kwekupedzisira kana kutumira.

• Kuwedzera Kwekubuda Kwezvinhu : Kuedzwa kwePCB otomatiki kunokurumidzisa maitiro uye kunoita kuti mayuniti akawanda akwanise kuyedzwa nekutumirwa pasina kunonoka, zvichiwedzera kushanda zvakanaka kwekugadzira.

Zvakajairwa Kukanganisa Kuonekwa muPCB Gungano kuburikidza neIn-Circuit Testing

In-Circuit Testing inoshanda zvakanyanya pakuona zvinokanganisika muPCB magungano, kusanganisira:

• Zvikamu Zvisipo kana Zvisina Kurongeka : ICT inosimbisa kuti zvikamu zvese zviri munzvimbo dzakakodzera uye kuti hapana chiripo, zvichiita kuti zvive nechokwadi chekuti zvinoshanda zvakanaka.

• Mabhiriji Mapfupi : Mabhiriji anosanganisa magetsi kana kubatana kusina kurongeka pakati pemapini kana matrace ari pedyo zvinogona kukonzera mapfupi, uye ICT inobatsira kuona matambudziko aya nekukasika.

• Macircuit Akavhurika : Maconnection akatyoka kana asina kusungirirwa zvakanaka anogona kukonzera macircuit akavhurika, zvichitadzisa bhodhi kushanda nemazvo.

• Zvikanganiso zveSoldering : Majoini asina kunaka esolder kana majoini anotonhora zvinogona kukonzera matambudziko ekubatana, ayo ICT inoongorora chigadzirwa chisati chaenderera mberi.

• Hunhu Hwakarurama hweZvikamu : ICT inoita kuti zvikamu zviiswe zvakanaka uye kuti zvinosangana nezvinodiwa nemagetsi.

Kuedzwa kweICT muPCB Assembly: Kusanganisa AOI, AXI, Flying Probe, Functional Test, Boundary Scan, uye Burn-in

Kuyedzwa kwemukati medunhu (ICT) kunoshanda pakusimbisa kukosha kwechikamu uye kubatana kwemagetsi paPCBA, asi hakufukidze maitiro ese ekukundikana—kunyanya pamabhodhi ane density yakakura, mapakeji epitch fine, uye majoini esolder akavanzwa. Kuti pave nekuvharwa kwakasimba kwezvikanganiso, ICT inowanzo shandiswa pamwe chete nedzimwe nzira dzekuongorora uye dzekuyedza sechikamu chechirongwa chebvunzo chePCBA chakatsanangurwa nemutengi.

Pazasi pane nzira dzakajairika dzinobatsira ICT uye dzinobatsira kuvandudza kufukidza kwebvunzo yese kuburikidza nekunyatsorongeka kwekuisa, mhando yesolder, hukama hwakabatana, uye maitiro ekushanda chaiwo.

1) Otomatiki Optical Optical Review (AOI)

Otomatiki Optical Inspection (AOI) inzira yekuongorora nemaziso isingabatanidzi zvinhu zvinoonekwa uye zvinokanganisa nzvimbo zvakaita sezvimedu zvisipo, zvikanganiso zvepolarity/orientation, offsets, uye zvinoonekwa zvisina kunaka zve solder. AOI inozadzisa ICT nekubata zvikanganiso zvemakanika/maziso zvinogona kuramba zvichikunda kuongororwa kwemagetsi, zvichipa kusimbiswa kwemhando ye assembly.

2) Kuongorora X-ray (AXI)

Kune mapakeji ane majoini akavanzwa—akadai seBGAs nezvimwe zvikamu zvinopera pasi— X-ray inspection (AXI) inobatsira kuongorora kubatana kwemukati mejoini pasina kupatsanurwa. Inowanzoshandiswa kuona zvikanganiso zvakaita sekuvharika, kushongedzwa kusina kukwana, kubatanidza, kana majoini anotonhora asingaonekwe kunze uye anogona kunge asina kufukidzwa zvizere neICT probing access.

3) Kuedzwa kweFlying Probe

Kuyedza flying probe kunoshandisa maprobe anofambiswa kuita zviyero zvemagetsi pasina chinhu chakagadzirwa nemaoko. Inowanzo shandiswa pakugadzira ma prototypes uye kuvaka vhoriyamu yakaderera kusvika pakati kana kuchinjika kuchikosha. Kana yakabatana neICT, flying probe inogona kutsigira kufukidzwa kwakawedzerwa pamagadzirirwo ane mukana mudiki wekuwana michina kana kugadziriswa kuri kuchinja.

4) Kuedzwa Kwebasa (FCT)

Kunyange zvazvo ICT ichinyanya kutarisa pazvikamu nemambure, bvunzo dzekushanda (FCT) dzinosimbisa PCBA padanho rehurongwa pasi pemamiriro ekushanda (maitiro ekugadzirisa simba, I/O, kutaurirana, mashandiro emutoro, nezvimwewo). Kubatanidza ICT neFCT kunovandudza chivimbo chekuti bhodhi rine simba remagetsi uye rinoshanda nemazvo mukushandiswa kwaro kwarinoda.

5) Kuskena Muganho (JTAG)

Kune magadzirirwo akaomarara uko kuongorora kwemuviri kwakaoma, boundary scan (JTAG) inogona kuyedza maconnections uye mamwe maitiro edanho remudziyo kuburikidza ne scan chains, kuwedzera kufukidzwa kwakapoteredza fine-pitch ICs neBGAs. Kana ikashandiswa pamwe chete neICT, boundary scan inogona kubatsira kuvhara mipata yekuyedza pama nodes asingawanikwe nyore.

6) Kuedzwa kweKupisa Mukati

Kuyedzwa kwekutsva mukati kunobatanidza kushanda kwenguva refu pasi pemamiriro ekumanikidzwa akadzorwa kuti kuonekwe kutadza kwevana vachiri vadiki. Kana zvichidikanwa nezvinodiwa nekuvimbika, kutsva mukati kunogona kuwedzera ICT nekuona zvikamu zvemukati kana matambudziko anongoerekana asaonekwa panguva yekuyedzwa kwemagetsi kwenguva pfupi.

Nekubatanidza ICT nenzira dzekuongorora dzinoenderana uye nzira dzekuyedza, vagadziri vanogona kuvandudza kuonekwa kwezvikanganiso pamagetsi, makanika, uye mashandiro - kunyanya kune maPCB akabatanidzwa akaomarara kana akavimbika zvakanyanya. Musanganiswa wekupedzisira unowanzo tsanangurwa nezvinodiwa nevatengi, huwandu hwengozi yechigadzirwa, uye kugona kwekuyedza dhizaini.

Mabhenefiti eIn-Circuit Testing yePCB Assembly

• Kubudirira Kwakanyanya Mukugadzira : Nekuita kuti bvunzo dziitwe otomatiki, ICT inoderedza kudiwa kwekuongorora nemaoko, zvichiita kuti basa rekugadzira rikurumidze.

• Hunhu Hwakanaka Hwechigadzirwa : ICT inoita kuti PCB yega yega isanganiswe ikwane zvinodiwa nemagetsi, zvichikonzera zvigadzirwa zvemhando yepamusoro.

• Kukurumidza Kusvika Pamusika : ICT inobatsira kuona zvikanganiso nekukurumidza, zvichibvumira vagadziri kugadzirisa matambudziko nekukurumidza uye kuona kuti zvigadzirwa zvinotumirwa nekukurumidza.

• Inochengetedza Mari : Mari yekutanga inoshandiswa mumidziyo yeICT inoderedzwa nekuchengetedza kwenguva refu kubva pakudzikira kwekugadzirisa, mitengo yakaderera yezvimedu, uye kuvandudzwa kwekushanda zvakanaka kwekugadzira.

• Kuvimbika Kwakawedzerwa : Masangano ePCB anobudirira muICT haawanzokundikana mubasa iri, zvichivandudza kuvimbika uye kugutsikana kwevatengi.
