Functional Testing Mano

Kuedza kwakazara kunoshandiswa mukati mekuvandudzwa kwechigadzirwa chitsva kunochengetedza mari yemutengi uku ichideredza kugadzira kuderera. Pamatanho ekutanga, in-circuit bvunzo, automated optical inspection (AOI) uye Agilent 5DX ongororo inopa yakakosha mhinduro inogonesa kugadzirisa panguva. Zvino kushanda uye kuongororwa kwekushandisa kunoitwa kune ega mutengi maratidziro asati aoma kwezvakatipoteredza kushushikana kutarisisa kunoratidza kuvimbika kwechigadzirwa. Kana zvasvika pakuunza chigadzirwa chitsva, POE suite yekushanda uye yekuyedza kugona inova nechokwadi chekuti ichivaka chaiko kekutanga, uye nekupa mhinduro inopfuura zvinotarisirwa.

Functional Test:

Nhanho Yekupedzisira Yekugadzira

Functional test (FCT) inoshandiswa sedanho rekupedzisira rekugadzira. Inopa kupfuudza/kutadza kutsunga pamaPCB apera asati atumirwa. Chinangwa cheFCT mukugadzira ndechekusimbisa kuti chigadzirwa chehardware hachina hurema izvo zvinogona, neimwe nzira, kukanganisa kushanda kwechigadzirwa muhurongwa hwekushandisa.

Muchidimbu, FCT inoongorora mashandiro ePCB nemaitiro ayo. Izvo zvakakosha kusimbisa kuti izvo zvinodikanwa zvebvunzo inoshanda, kukura kwayo, uye maitiro anosiyana zvakanyanya kubva kuPCB kuenda kuPCB uye system kune system.

Vanoshanda testers vanowanzo pindirana nePCB iri pasi pekuyedzwa kuburikidza neyayo yekumucheto yekubatanidza kana bvunzo-yekuongorora. Iyi bvunzo inotevedzera yekupedzisira nharaunda yemagetsi umo PCB ichashandiswa.

Iyo yakajairika fomu yebvunzo inoshanda inongoratidza kuti PCB iri kushanda nemazvo. Mimwe miedzo yakaoma inoshanda inosanganisira kuchovha bhasikoro PCB kuburikidza nehuwandu hwakakwana hwebvunzo dzekushanda.
Mutengi Zvakanakira zveFuctional Test:

● Muedzo unoshanda unofananidzira nharaunda yekushanda yechigadzirwa chiri mukuyedzwa nokudaro zvichideredza mutengo unodhura wemutengi kuti ape iwo chaiwo ekuyedza michina.
● Inobvisa kudiwa kweinodhura system bvunzo mune dzimwe nguva, iyo inoponesa iyo OEM nguva yakawanda uye zviwanikwa zvemari.
● Inogona kutarisa kushanda kwechigadzirwa chero kupi zvako kubva pa50% kusvika ku100% yechigadzirwa chiri kutumirwa nekudaro ichideredza nguva uye simba paOEM kuti iongorore nekuigadzirisa.
● Hungwaru kuyedza mainjiniya vanogona kuburitsa chibereko chakanyanya kubva muyedzo inoshanda zvichibva zvaita kuti ive chishandiso chinonyatso shanda papfupi yesystem test.
● Kushanda bvunzo kunosimudzira mamwe marudzi ebvunzo akadai seICT uye flying probe bvunzo, zvichiita kuti chigadzirwa chiwedzere kusimba uye chisina kukanganisa.

Muedzo unoshanda unotevedzera kana kutevedzera nharaunda yekushanda kwechigadzirwa kuti utarise kushanda kwayo chaiko. Mamiriro ekunze ane chero mudziyo unotaurirana nemudziyo uri mukuyedzwa (DUT), semuenzaniso, magetsi eDUT kana kuti chirongwa chinotakura zvinodiwa kuti DUT ishande nemazvo.

Iyo PCB inoiswa pasi pekutevedzana kwezviratidzo uye magetsi emagetsi. Mhinduro dzinotariswa panzvimbo dzakatarwa kuti ive nechokwadi chekuti kushanda kwacho kwakarurama. Muedzo unowanzoitwa zvinoenderana neOEM bvunzo mainjiniya, uyo anotsanangura zvakatemwa uye maitiro ebvunzo. Muedzo uyu wakanyanya pakuona zvisirizvo zvechikamu kukosha, kutadza kushanda uye kutadza kweparametric.

Test software, dzimwe nguva inodaidzwa kunzi firmware, inobvumira vanogadzira mutsara vanoshanda kuti vaite bvunzo inoshanda nenzira otomatiki kuburikidza nekombuta. Kuti uite izvi, software inotaurirana nekunze zvinorongwa zviridzwa sedhijitari multi-mita, I/O mabhodhi, zviteshi zvekutaurirana. Iyo software yakasanganiswa neiyo inopindirana zviridzwa neDUT inoita kuti zvikwanise kuita FCT.

Vimba neSavvy EMS Provider

Smart OEMs inotsamira kune ane mukurumbira EMS mupi kuti ubatanidze bvunzo sechikamu chekugadzira kwayo chigadzirwa uye kusangana. Kambani yeEMS inowedzera kuchinjika kune imwe imba yekuchengetera tekinoroji yeOEM. Ane ruzivo EMS mupi anogadzira uye anounganidza huwandu hwakawanda hwePCB zvigadzirwa zveboka rakasiyana rakasiyana revatengi. Nekudaro, inounganidza yakakura kwazvo arsenal yeruzivo, ruzivo uye hunyanzvi kupfuura vatengi vavo veOEM.

Vatengi veOEM vanogona kubatsirwa zvakanyanya nekushanda neanoziva EMS mupi. Chikonzero chikuru ndeye ane ruzivo uye ane ruzivo EMS mupi anokwevera kubva kune yayo ruzivo hwaro uye anoita akakosha mazano ane chekuita neakasiyana ekuvimbika matekiniki uye zviyero. Nekuda kweizvozvo, mupi weEMS anogona kunge ari pachinzvimbo chakanakisa chekubatsira OEM kuongorora sarudzo dzayo dzekuyedza uye kupa zano nzira dzakanakisa dzekuyedza yekuvandudza mashandiro echigadzirwa, kugadzira, mhando, kuvimbika, uye zvakanyanya kukosha, mutengo.

Yedu Kukosha Injiniya Services (VES)
POE kukosha kweinjiniya masevhisi anogonesa vatengi vedu kukwirisa chigadzirwa kugadzira uye kuita kwemhando. Isu tinotarisa pane ese masikirwo ekugadzira uye kugadzira maitiro - kuongorora zvese zvinokanganisa pamutengo, basa, chirongwa chechirongwa uye zvese zvinodiwa.

ICT Inoita Kuongorora Kwakazara

Mukuyedzwa kwedunhu (ICT) inowanzo shandiswa pane zvigadzirwa zvakura, kunyanya mukugadzira subcontract. Inoshandisa mubhedha-we-zvipikiri bvunzo gadziriso kuti uwane akawanda ebvunzo mapoinzi paPCB pazasi. Iine nzvimbo dzekuwana dzakakwana, ICT inogona kufambisa masaini ebvunzo kupinda nekubuda muPCB nekumhanya kwakanyanya kuita ongororo yezvikamu nemaseketi.

Mubhedha wezvipikiri tester chinyakare chemagetsi test fixture. Iine mapini akawanda akaiswa mumakomba, ayo anorongeka achishandisa mapini ekushandisa kugadzira

kubata nema test point pane yakadhindwa redunhu board uye zvakare akabatanidzwa kune yekuyeresa unit newaya. Midziyo iyi ine nhevedzano yemapini madiki, echitubu akaremerwa epogo achisangana nenodhi imwe mukutenderera kwemudziyo urikuedzwa (DUT).

Nekudzvanya DUT pasi pamubhedha wezvipikiri, kuonana kwakavimbika kunogona kuitwa nekukasira nemazana uye mune dzimwe nguva zviuru zvenzvimbo dzekuyedza dzemunhu mukati medunhu reDUT. Zvishandiso zvakaedzwa pamubhedha wezvipikiri tester zvinogona kuratidza kadiki kana dimple rinobva kune akapinza matipi epogo pini anoshandiswa mukugadzirisa.
Zvinotora mavhiki mashoma kugadzira iyo ICT fixture uye kuita hurongwa hwayo. Chigadziriso chinogona kunge chiri vacuum kana kudzvanya-pasi. Vacuum zvigadziriso zvinopa zvirinani chiratidzo chekuverenga maringe nerudzi rwekudzvanya-pasi. Kune rimwe divi, zvigadziriso zvevacuum zvinodhura nekuda kwekuoma kwazvo kugadzira. Mubhedha wezvipikiri kana mu-circuit tester ndiyo yakajairika uye yakakurumbira munharaunda yekugadzira kontrakiti.
 

ICT inopa OEM mutengi mabhenefiti akadai se:

● Kunyange zvazvo chigadzirwa chinodhura chinodiwa, ICT inovhara 100% yekuongorora kuitira kuti simba rose uye pasi pfupi zvionekwe.
● Kuongorora kweICT kunopa simba pakuedza uye kubvisa kugadzirisa kwevatengi kunoda kusvika paZERO.
● ICT haitore nguva yakareba kuti iite, semuenzaniso kana kuongorora kubhururuka kuchitora maminitsi makumi maviri kana kupfuura, ICT panguva imwe chete inogona kutora miniti kana kupfuura.
● Inotarisa uye inoona zvikabudura, kuvhura, kushayikwa kwezvikamu, zvisizvo zvakakosha zvikamu, zvisizvo polarities, zvakakanganisika zvikamu uye zvino zvinoputika mumatunhu.
● Yakanyanya kuvimbika uye yakazara bvunzo inobata zvese zvinokanganisa kugadzira, dhizaini kukanganisa, uye kukanganisa.
● Testing platform inowanikwa muWindows pamwe neUNIX, zvichiita kuti ive pasi rose kune zvakawanda zvekuedza zvinodiwa.
● Test development interface uye nharaunda yekushanda yakavakirwa pazviyero zveyakavhurika sisitimu ine kukurumidza kusanganisa mune yeOEM mutengi maitiro aripo.

ICT ndiyo inonyanya kunetesa, inonetsa, uye inodhura mhando yekuyedza. Nekudaro, ICT yakanakira zvigadzirwa zvevakuru zvinoda kugadzirwa kwevhoriyamu. Iyo inomhanyisa chiratidzo chemagetsi kutarisa mazinga evoltage uye kuyerwa kwekupokana panzvimbo dzakasiyana dzebhodhi. ICT yakanakisa pakuona kutadza kweparametric, dhizaini ine chekuita nekukanganisa uye kutadza kwechikamu.
