Umhlahlandlela Wokukhiqiza we-PCB kanye neKhamera Yokushisa Ephathekayo

Imodyuli yokuthwebula izithombe ezishisayo ivame ukuba yingxenye yekhamera ye-infrared ephathwayo umthengi angeke akwazi ukuyilimaza ngesikhathi sokulungiswa kabusha. Kodwa ikhotheshini ye- PCB yekhamera eshisayo ephathekayo ingase imboze ibhodi lokusingatha kuphela, ishiye ukuthengwa kwemodyuli, ukufakwa kwesokhethi kanye nokuqinisekiswa kwangemva kokuhlanganiswa ngaphandle kwentengo ecashuniwe. Kubahlinzeki be-PCB assembly be-OEM abaqhathanisa izithombe ezishisayo, lokho kukhishwa kubaluleke kakhulu kunomehluko omncane ezindlekweni zebhodi elingenalutho.

I-Highleap Electronics inikeza ukwenziwa kwe-PCB, ukutholakala kwezingxenye kanye nokuhlanganiswa kwe-PCBA kwezinhlobo eziningi zehadiwe kagesi. Kumlawuli wekhamera ye-infrared noma isithwali senzwa yokushisa, ingxoxo yokukhiqiza iqala ngokwakhiwa kwe-PCB yangempela, uhlu lwezingxenye oluvunyiwe kanye nokulandelana kokufakwa. Izinsizakalo ezifanayo zasefektri ziyasebenza nakubalawuli bezimboni, imishini yokuxhumana kanye nezinye izinto ze-elektroniki ze-OEM; ibhodi ngalinye lithola inqubo ngokusekelwe kumklamo walo okhishwe.

Ingabe i-Uncooled Microbolometer ifakiwe ku-PCBA Quote yakho?

Kwi -PCB yekhamera yokushisa , ukuthengwa okubalulekile kungaba yi-microbolometer engapholi efakwe kusokhethi noma i-core ehlanganisiwe yesithombe sokushisa. Umklamo ohlukile ungabeka isikhombikubona senzwa ebhodini elilodwa kanye ne-electronics yokucubungula izithombe kwelinye. Igama elithi “ikhamera” noma inani lezingxenye eziphelele azitsheli i-assembler ukuthi i-module ebizayo izonikezwa, ifakwe noma ihlolwe.

Chaza indawo yokufaka ngaphambi kokuba inqubo yokunamathisela ivunyelwe

Amanye amamojula okushisa anamathela ngesokhethi elichazwe ngumkhiqizi; amanye anemikhawulo ehlukile yokufaka noma yokucubungula. I-OEM kufanele inikeze inombolo yengxenye eqondile yemojula, umdwebo womshini kanye nemiyalelo yokuphatha umhlinzeki. Uma indlela evunyiwe idinga ukufakwa ngemva kokugeleza kabusha kwebhodi, isikrini sikagesi se-base-PCBA singase sibe khona ngaphambi kokuba i-core ifakwe. Lokho kunganciphisa ukuvezwa kwezingxenye ezibizayo ukuze ziphinde zisebenze, yize ukulandelana kumele kuhambisane nomklamo wangempela kanye nokufinyelela kokuhlola.

Ngokuhlanganisa i-PCB yekhamera ye-infrared ye-OEM , i-oda lokuthenga kufanele libonise imithwalo yemfanelo emithathu ehlukene: ukuthi ubani othola imodyuli, ukuthi ubani owenza isinyathelo sokunamathisela esivunyiwe, nokuthi ubani okhokhela noma ohlola imodyuli ehlulekile. Qopha isimo esingenayo kanye nokuhlangana kwenombolo ye-serial lapho kudingeka ukulandelelwa. Lokhu kuqhathanisa okuwusizo kakhulu phakathi kwabaphakeli kunokucela ngamunye intengo eyodwa "yekhamera ye-thermal PCBA" engachazeki.

Indlela Yakho Yokushisa Yeprosesa Ingashintsha Indawo Yenzwa

Ikhamera yokushisa ephathwa ngesandla ingahlanganisa iprosesa yesithombe esifudumele, ishaja yebhethri, isibonisi kanye nenzwa ezwela ukushisa endlini eyodwa encane. Ngisho noma iprosesa ihlala ngaphakathi komkhawulo wayo wokushisa wezingxenye, ukushisa okwenziwa ngethusi le-PCB noma i-chassis kungashintsha indawo yokushisa ezungeze umongo wesithombe.

Vikela indlela yokushisa eqinisekisiwe, hhayi iprosesa kuphela

Kuphrojekthi yokukhiqiza i-PCB yekhamera ye-infrared ephathekayo , ukwakheka okukhishwe kungacacisa ama-array asebenzisa ukushisa, ukuthululwa kwethusi, ukugcina izingxenye noma ama-contact pad e-heat spreader. Ushintsho lokwenziwa oluthuthukisa ukupholisa kwedivayisi eyodwa lungasondeza ukushisa ngengozi kumojuli. Ingxoxo yethu ngezindlela zokusabalalisa ukushisa kwe-PCB kanye ne-thermal-via inikeza isizinda esiwusizo, kodwa ukuhlanganiswa kwekhamera ye-thermal kumele kulandele i-geometry yebhodi evunyiwe kanye nendlela yokushisa yomshini.

Ukubuyekezwa kokukhiqiza kufanele kuveze noma yiluphi ushintsho oluhlongozwayo ekuqoqweni, ibhalansi yethusi, ukufakwa kweshaja noma indawo yokushisa. Umnikazi womkhiqizo kufanele ahlole umphumela wawo ngesikhathi sokufudumeza, ukuthwebula izithombe okuqhubekayo kanye nokushaja, njengoba kufanele. Ukwenziwa kwebhodi kanye nokuhlolwa kwe-PCBA kungaqinisekisa ukwakhiwa okucacisiwe; abakwazi ukuqinisekisa ngokuzimela ukunemba kwe-radiometry ngaphakathi kwendawo ebiyelwe eqediwe.

Uma Isixhumi seKhamera ye-FPC Sifanelana ne-PCB Kodwa Hhayi i-Enclosure

Isokhethi elincane le-FPC lingafakwa endaweni efanele futhi livimbele ikhebula lokubonisa ukuthi lingafakwa uma indlu yekhamera ye-infrared ivaliwe. Isiqondiso sokukhwelana, ukufinyelela kwe-latch, ukuphakama kwesixhumi kanye nesiqondiso sokugoba kwe-flex konke kuthinta i-assembly. Lezi yizithiyo ezisebenzayo kubathengi abafuna i-FPC yekhamera kanye ne-PCB assembly ye-thermal sensor , hhayi imininingwane emincane yokuqeda.

Kumiklamo enezibonisi ezihlukile, izinzwa noma izilawuli eziguquguqukayo, nikeza umdwebo obonisa uhlangothi kanye nesiqondiso sokufaka ikhebula eceleni kwefayela lokubeka. Izinketho zokuxhumanisa zekhamera ze-FPC zibalulekile lapho isethi yebhodi evunyiwe ifaka uxhumano oluguquguqukayo; ifektri akufanele ingeze isekethe eguquguqukayo kumklamo osebenzisa izixhumi noma izintambo ezivamile.

Ukubuyekezwa okufanayo ngokomzimba kufanele kufake ama-datum e-optical-axis, indawo yokufaka imbobo, ukuphakama kokuma kanye nokuthi inzwa ifakiwe yini ngaphambi noma ngemva kokuhlanganiswa kwe-enclosure. Ukuhlolwa kokulingana kwemishini kwesihloko sokuqala kungabona ukungalingani kwesixhumi ngaphambi koku-oda okuphindaphindiwe, ngisho noma ukuqhubeka kukagesi sekudlulile.

Amabhodi Amabili Okuthwebula Izithombe Ezishisayo Angadinga Izindlela Ezihlukene Zokuhlanganisa

Isithwali esincane senzwa ye-infrared esinesokhethi kanye nama-passive ambalwa asidingi inqubo efanayo yokukhiqiza njenge- PCBA yesilawuli sekhamera yokuthwebula izithombe ezishisayo esindayo enememori yangaphandle, amadivayisi okuphatha amandla, i-USB kanye nezixhumi zesithombe ezisheshayo. Lokhu kokugcina kungadinga ukulawulwa kwe-impedance yezingqimba eziningi noma ukuhlolwa kwephakheji okuthuthukisiwe; okokuqala kungalawulwa kakhulu ukulungiswa kwesokhethi kanye nokuphathwa kwemojuli.

Ukuhlanganiswa kwe-fine-pitch kukhethwa ngokwengozi yephakheji

Kwi-PCB yekhamera yokushisa enobuningi obukhulu, i-processor footprint evunyiwe, i-BGA escape, ama-QFN thermal pads kanye ne-memory routing kunquma ukwenziwa kanye nezidingo ze-SMT. Lapho amalunga e-solder afihliwe edinga khona, ukuhlolwa kwe-X-ray kokuxhumeka kwe-BGA solder kungase kwenezele ekuhlolweni kokukhanya. Ukupakishwa kwe-BGA noma ilebula yekhamera yokushisa akusho ngokuzenzakalelayo ukuthi ibhodi idinga i-HDI noma i-X-ray kuwo wonke amayunithi.

Izinsizakalo zokukhiqiza ze-elekthronikhi ze-Highleap zama-PCBA achazwe ngamakhasimende zihlanganisa imikhakha ehlukene yomkhiqizo kanye nezidingo zokuhlanganisa. Ngezinhlelo ezidinga umhlinzeki oyedwa ukuxhumanisa ukwenziwa kwebhodi elivunyiwe, ukuthengwa kwezingxenye kanye nokuhlanganiswa kwe-PCB, inketho yokuhlanganisa i-turnkey PCB ingaxoxwa. Ama-cores okuthwebula izithombe abizayo, ukunamathiselwa kwekhebula, uhlelo lwe-firmware kanye nanoma yikuphi ukuhlolwa okukhethekile kufanele kufakwe kuleyo khotheshini kuphela lapho kuvunyelwene khona ngokucacile.

Isithombe Esishisayo Akusona Ubufakazi Bokunemba Kwezinga Lokushisa

Ekuhlolweni kokusebenza kwe-PCBA yekhamera yokushisa , ukubona isithombe se-infrared bukhoma kufakazela ukuthi okungenani ingxenye yendlela yamandla, iprosesa kanye nedatha yenzwa iyasebenza. Akuqinisekisi ukuthi ithuluzi lilinganisa izinga lokushisa ngokunembile. Imininingwane yokuthengwa kufanele igcine lezi zigaba zokwamukelwa zihlukile esikhundleni sokucela ifektri ye-PCB ukuthi ikwenzele “ukuhlolwa kokushisa okungu-100%” okungachazwanga.

Uhlelo lokuhlola lwezinga lebhodi lungachaza ukuhlolwa okulandelayo, kuye ngesekethe langempela kanye ne-fixture enikeziwe:

• Ngaphambi kokufakwa kwe-core, uma kungenzeka: qinisekisa ama-power rails, i-boot kanye nokuziphatha kwememori ngaphandle kokufaka engcupheni imojuli yokuthwebula izithombe.
• Ngemva kokufakwa kwe-core: thola inzwa, qinisekisa isixhumanisi sayo sokuxhumana bese uhlola umphumela wesithombe-idatha noma impendulo yokuxilonga echaziwe.
• Ukulawula ukucushwa: qinisekisa i-firmware evunyiwe bese uqopha imodyuli noma i-PCBA serial association uma kudingeka yi-OEM.

Ukulinganiswa kwe-FFC kanye ne-radiometric akukwazi ukushintshaniswa

Amanye ama-thermal cores enza ukulungiswa kwe-flat-field (FFC) noma ukulungiswa okungalingani ukuze kuthuthukiswe ukufana kwesithombe. Ukufundwa kwezinga lokushisa elilinganisiwe, ngokuphambene, kungancika ku-optics, i-target emissivity, izinga lokushisa elivalekile, ifasitela lokushisa kanye nendlela yokunciphisa umkhiqizo. Uma kudingeka ukuhlolwa kwe-radiometric okwenziwa efektri, i-OEM kumele ichaze i-target elinganisiwe, izimo, imishini, inqubo kanye nemikhawulo yokupasa/yokwehluleka. Ukuhlolwa kukagesi okuvamile kukodwa akukwazi ukusungula ukunemba kokulinganisa kwekhamera eqediwe.

Khiya Isakhiwo Esamukelwe Ngaphambi Koku-oda Kokukhiqiza Okulandelayo

Ku -PCBA yesithombe sokushisa esivela ku-prototype kuya ekukhiqizweni , isithombe esamukelekile kuyunithi yokuhlola kufanele sihambisane namarekhodi avumela ukuhlanganiswa okufanayo ukuthi kukhiqizwe kabusha. Amadokhumenti abaluleke kakhulu akuzona izitifiketi ezijwayelekile; yisibuyekezo esivunyiwe se-imaging-core, ibhodi kanye nokubuyekezwa kwe-BOM, kanye nokucushwa kokuhlolwa okusungule ukwamukelwa.

Ngaphambi kokufaka i-oda eliphindaphindwayo, cela umhlinzeki ukuthi agcine:

• Isimo esiyinhloko kanye nokuthola ulwazi: inombolo yengxenye ye-thermal-module, ubunikazi bokuhlinzeka, izinto ezithathelwa indawo ezivunyiwe, ukuphathwa okungenayo kanye nokulandelela okuhleliwe lapho kuchazwe khona.
• Irekhodi lomshini kanye nomhlangano: ukuqondiswa kwesokhethi noma i-FPC, isigaba sokufakwa, imikhawulo yokugeleza kabusha kanye nanoma yikuphi ukulingana kwento yokuqala noma ubufakazi bokuhlanganiswa kwe-solder.
• Irekhodi lokwamukelwa: ukubuyekezwa kwe-firmware, inguqulo ye-fixture, ukuhlolwa kukagesi, ukuhlolwa kwendlela yesithombe kanye nomsebenzi wokulinganisa ovunyelwene ngawo ngokwehlukana.

Ngobuningi obubikezelwe, ukuhlela ukukhiqizwa kwe-PCBA yomthamo wokukhiqiza kuba yinto efanelekile kuma-thermal cores ahamba phambili isikhathi eside, umthamo we-feeder kanye nowokufakwa, izinguquko zezinto ezivunyiwe kanye nezinyathelo zokuhlanganisa eziphindaphindwayo. Abathengi kufanele bacele amanani e-lot yokuqala kanye nobuningi obuphindaphindwayo obulindelekile ngokwehlukana, ikakhulukazi uma izindleko zemodyuli noma isikhathi sokuhlola sibusa izindleko zebhodi elihlanganisiwe.

Ukuze ucele isilinganiso sokukhiqiza se-PCB sekhamera eshisayo ephathekayo , thumela amafayela e-Gerber noma e-ODB++, i-stack-up, imidwebo yokuhlanganisa, i-BOM evunyiwe, imiyalelo yokufaka imodyuli, izinhlobo zebhodi kanye nobuningi obuqondiwe. Engeza ukuhlolwa okuqondile noma ukuhlolwa kokulethwa okudingayo. I-Highleap ingabuyekeza izidingo zokwenziwa kanye nokuhlanganiswa kwale phrojekthi yokuthwebula izithombe—noma kwezinye izinhlelo ze-PCB kanye ne-PCBA ze-elekthronikhi—ngokumelene nobubanzi bokukhiqiza obucacile.
