Ama-PCB Okukhanya Kwe-LED Angaqhumi: Amabhodi Endawo Eyingozi, Abashayeli Nokuhlanganiswa

Ukukhanya okuvimbela ukuqhuma kuvikela izindawo lapho inhlansi eyodwa noma indawo eshisayo ingavuthela khona igesi, umhwamuko, noma uthuli — izitshalo zamakhemikhali kaphethiloli, izindawo zokuhluza, amapulatifomu asogwini lolwandle, ukuphathwa kokusanhlamvu, ukumbiwa kwezimayini, izitolo zokupenda, kanye nezindawo zokugcina uphethiloli. Indawo eqinisekisiwe yenza umsebenzi oyinhloko wokuvimba noma yikuphi ukuvuthela, kodwa izinto zikagesi ezingaphakathi kusadingeka zenziwe ngendlela yokuthi zingabi umthombo wokuvuthela kwasekuqaleni: izinga lokushisa elilawulwayo, ukungabi namandla abonakalayo, kanye nezingxenye ezisinda ezindaweni ezinzima, ezigqwalisayo, nezinyakazayo iminyaka eminingi.

I-Highleap Electronics iyifektri ephelele yokukhiqiza i-PCB kanye ne-PCBA , futhi ukukhanyisa endaweni enobungozi kungenye yezinhlelo zezimboni ezidingayo esizakhela zona. Asiqinisekisi izibani eziqediwe - okungukuthi indima yomenzi wezinto zokwakha kanye nomzimba owazisiwe - kodwa sakha amabhodi enjini yokukhanya, umshayeli, i-surge, kanye nokulawula ngokwezidingo zokushisa, ukukhukhuleka, kanye nokuvikela okuvumela isibani ukuthi sidlule isitifiketi futhi sisinde ensimini. Lo mhlahlandlela uchaza ukuthi amabhodi asekela kanjani ukuhambisana nendawo enobungozi kanye nalokho esikukhiqizayo. Isigaba esibanzi sitholakala ekhasini lethu lomkhiqizi we-PCB yezibani ze-LED.

Impendulo esheshayo: Esibanini esingaqhumi, indawo ebiyelwe eqinisekisiwe iqukethe ukusha, kodwa ama-PCB kumele agweme ukuyidala: injini yokukhanya kumele isebenze ekushiseni okuphansi, okulawulwayo, umshayeli kumele afakwe ebhodweni noma agqunywe emvelweni, futhi ukwakheka kumele kuhloniphe ukukhukhuleka kanye nokususwa ukuze kungabikho ndlela ye-arc. I-Highleap Electronics yakha futhi ihlanganise wonke lawa mabhodi ukuze ahambisane nezindawo ezibiyelwe ezilinganiselwe yi-Ex/ATEX/IECEx, ku-IPC Class 3 nge-potting, i-conformal coating, kanye ne-burn-in, MOQ 1.

Lokho “okungaqhumi” okufunwa yi-electronics empeleni

Kuyasiza ukucacisa amagama. Isibani "esingaqhumi" noma "esingangeni ilangabi" (Ex d) sisebenzisa indawo eqinile eyenzelwe ukuvimba ukuqhuma kwangaphakathi futhi sikuvimbele ukuthi kusakazeke emoyeni ozungezile. Eminye imiqondo yokuvikela - ukuphepha okwandisiwe (Ex e), ukumbozwa (Ex m), kanye nokuphepha kwangaphakathi (Ex i) - kunciphisa amandla atholakalayo okushisa noma yini kwasekuqaleni. Izinto zangempela zivame ukuhlanganisa imiqondo, futhi amabhodi kufanele avumelane nanoma yikuphi okusebenzayo.

Kungakhathaliseki ukuthi uyini umqondo, izinto zobuchwepheshe zabelana ngezidingo ezimbalwa eziqinile: izinga lokushisa eliphezulu lobuso kumele lihlale ngaphakathi kwesigaba sokushisa sezinto (isilinganiso se-T) ngisho noma linamandla aphelele kanye nendawo ephezulu; akumelwe kube khona ingxenye eshisayo noma umthombo we-arc oveziwe ongabhekwanga yindlela yokuvikela; futhi ibhodi ngalinye kumele lisinde ezimweni ezibolayo, ezinomswakama, ezidlidlizayo, nezishintshashintshayo zokushisa ngaphandle kokuwohloka. Ngakho-ke ibhodi laklanywa ngokuzungeza izinga lokushisa kanye nokuhlukaniswa kuqala, bese kuthi ukukhanya kuphume okwesibili.

Indlela i-PCB esekela ngayo ukuthobela imithetho yendawo enobungozi

I-PCB ayinaso isitifiketi se-Ex sodwa — isitifiketi sisebenza ku-luminaire esiqediwe, esihlolwe yinhlangano eyazisiwe ngokumelene nezinga elifanele (uchungechunge lwe-IEC/EN 60079, kanye nezinhlelo zesifunda ezifana ne-ATEX eYurophu, i-IECEx emhlabeni jikelele, kanye ne-UL/CSA yezinhlelo ze-North American Class/Division and Zone). Kodwa ukwakheka kwebhodi kunquma ukuthi i-luminaire ingadlula yini, futhi umenzi oqonda lokhu wakha ngendlela ehlukile kakhulu kuleyo eyiphatha njengenjini yokukhanya ejwayelekile.

Lezi yizici ezingeni lebhodi ezisekela ukuthobela imithetho yendawo enobungozi, kanye nendlela esiziklama ngayo ngasinye:

• Izinga lokushisa elilawulwayo (i-T-class) — isici esibaluleke kakhulu. Injini elula kanye nomshayeli kumele bagcine yonke indawo ingaphansi komkhawulo wezinga lokushisa ledivayisi. Siklama Idizayini yokushisa ye-LED bese ukhetha insimbi-core i-substrate ukuze izinga lokushisa lokuhlangana kanye nobuso lihlale ngaphakathi kwesigaba esinomkhawulo, ngoba ibhodi elisebenza ngokushisa lingavimbela indawo ebiyelwe engahambisani nemithetho.
• Ukuphahlazeka nokususwa kwezindawo — isikhala esanele phakathi kwabaqhubi bezintambo ezikhundleni ezahlukene sivimbela ukulandelela kanye nokugoba. Sibeka amabhodi ukuze sifinyelele amabanga okuhamba kanye nokususa i-voltage yokusebenza kanye nezinga lokungcola lidinge, okuyinto eqinile kunemikhuba evamile yokuhweba.
• Ukufakwa kwe-capsule kanye nokufakwa kwebhodwe (Ex m) — lapho umqondo wokuvikela uthembele ekufakweni kwe-capsulation, sifaka ibhodi ebhodini ukuze izingxenye zamandla zivalwe futhi zingakwazi ukuxhumana nomoya. I-Potting iphinde iphathe ukudlidliza nokugqwala ngesinyathelo esisodwa.
• Ukumboza okuhambisanayo — ngenxa yomswakama kanye nokumelana negesi ebolile, enamathela conformal ivikela ukuhlangana ezindaweni ezingalimaza ibhodi elingavikelekile.
• Ukunciphisa amandla ezingxenye — ngezingxenye eziphephile ngokwemvelo, izakhiwo kanye nokukhetha kwezingxenye kugcina amandla agciniwe futhi atholakalayo ngaphansi kwemingcele yokushisa; ibhodi lisekela ukwakheka kwesithiyo kunokulwa naso.
• Ukwakhiwa okuqinile — ithusi elinzima, ubuningi bamandla agcina ugesi, kanye nokuqeda okuthembekile kakhulu ngakho akukho lutho oluwohloka lube yiphutha empilweni yemishini.

Okubaluleke kakhulu, lokhu kufanele kuhlanganiswe nendawo ebiyelwe kanye nendlela yokuqinisekisa. Sisebenza ngokwesigaba sokucaciswa kanye nesigaba sokushisa somenzi wezinto zokwakha, sakha amabhodi ukuze isabelomali sokushisa, indlela yokuhlukanisa, kanye nokuvikela konke kuhambisane nalokho umzimba owazisiwe ozokuhlola. Lapho injini, umshayeli, kanye namabhodi okuvikela akhiwa ngumkhiqizi oyedwa ohlelweni olulodwa oluhlanganisiwe lokushisa kanye nokuhlukanisa, isibani sifinyelela isitifiketi ngokushesha futhi ngezihibe ezimbalwa zokuklama kabusha kunalapho amabhodi etholakala ngokwehlukana futhi kutholakale ukuthi awahambisani ngesikhathi sokuhlola.

Sinikeza amadokhumenti amakhasimende adingayo ukuze asekele isitifiketi sabo — izimemezelo zezinto ezibonakalayo, amarekhodi okwakha, idatha yokushisa, kanye nokulandeleka — ngenkathi sicacisa ukuthi isitifiketi ngokwaso singesesibani esiqediwe, esivivinyiwe.

Ibhodi libekwe ngaphakathi kwesibani esingaqhumi

Njengezinye izinto zezimboni, isibani esingaqhumi siwuhlelo lwamabhodi amaningi — futhi lapha ukuxhumanisa phakathi kwamabhodi akuyona nje indlela yokusebenza kahle, kuyingxenye yokuhlala ngaphakathi kwemvilophu yokuphepha. Ibhodi ngalinye liwumndeni we-PCB ohlukile, futhi ukuzakha ndawonye kuyindlela isabelomali sokushisa kanye nesokuhlukaniswa esigcinwa ngayo sihambisana:

• Injini ekhanyayo — i-aluminium noma ithusi-core i-PCB eyinhloko yensimbi yakhelwe ukushisa okuphansi kobuso ngaphakathi kwe-T-class yedivayisi, hhayi nje ukukhanya okuphezulu.
• Ibhodi lomshayeli - ibhodwe noma imbozwe I-PCB yomshayeli we-LED ngokunciphisa okulinganiselayo, njengoba ukushisa komshayeli kunegalelo kwisabelomali sokushisa okuphezulu okumele kuhlangatshezwane naso sonke isitsha.
• Ibhodi lokuvikela nokuhlinzwa — izindawo eziyingozi zezimboni nezangaphandle zibona izikhawu ezinzima; ithusi elinzima isigaba sokuvikela sivikela umshayeli futhi sivimbela amaphutha ukuthi angakhuli.
• Ibhodi lokulawula nokuqapha — ukufiphaza, ukushintsha, kanye nokuqapha izinga lokushisa noma amaphutha kwezinye izinto, ebhodini eline-voltage ephansi elihlanganiswe nomshayeli futhi elihlanganiswe nomshayeli kanye ne-logic yokuqapha.
• Ibhodi lesimo esiphuthumayo/lebhethri — izibani eziningi eziyingozi kumele zihlale zikhanya ngesikhathi sokucima, okunezela ibhethri kanye ibhodi lokuvikela ibhethri lokho ngokwako kufanele kuhlangabezane nemvelo.

Isizathu sokwakha konke lokhu nomkhiqizi oyedwa sibukhali lapha kunasekukhanyeni okuvamile. Isigaba sokushisa siyisabelomali esabelwana ngaso sonke ibhodi — uma umshayeli eshisa kakhulu kunalokho okuhleliwe, kudla umkhawulo odingwa yinjini, futhi i-fixture ingahluleka ukuqinisekiswa. Lapho imboni eyodwa iklama futhi ihlola yonke i-stack ohlelweni olulodwa lokushisa kanye nolokuhlukanisa, leso sabelomali sihlala sihambisana. Ukuthola amabhodi ngokwehlukana kumema uhlobo lokungafani oluvela kuphela ngesikhathi sokuhlolwa kwesitifiketi okubizayo.

Ubunjiniyela be-substrate, creepage, kanye ne-clearing

Imikhakha emibili yezinga lebhodi ifanelwe ukuqashelwa ngoba yilapho amabhodi endawo enobungozi ahluke khona kakhulu kumabhodi okukhanyisa avamile.

Ukukhethwa kwe-substrate kuqhutshwa yisigaba sokushisa. I-dielectric conductivity aluminium core ephezulu, noma i-copper-core lapho umthwalo uyidinga khona, igcina izinga lokushisa lobuso liphansi nge-margin. Ukuze uthole izinga lokushisa eliphezulu kakhulu noma izinto ezishintshashintshayo eziphezulu sisebenzisa izinto ezisetshenziswayo ze-ceramic (Al₂O₃ noma i-AlN), ezihlanganisa ukusebenza okuhle kakhulu kokushisa nomvuzo wezindawo ezinzima zokuzinza.

Ubunjiniyela bokudilika nokususa izintambo bugcina omqhubi bezindawo ezahlukene beqhelelene ngokwanele ukuvimbela ukulandelela nokugoba, ngobukhulu be-voltage yokusebenza kanye nezinga lokungcola kwemvelo. Endaweni eyingozi lokhu akuyona into evamile — i-arc yilokho kanye okukhona ukuze kuvinjelwe yonke into. Siklama la mabanga ngendlela elondolozayo futhi siwaqinisekise ngokuqhathanisa namathebula asezingeni elifanele.

Ndawonye, ​​izinqumo ze-substrate kanye ne-space zenza injini yokukhanya ejwayelekile ibe ibhodi elingaphila ngaphakathi kwe-fixture eqinisekisiwe engaqhumi.

Ukufaka izimbiza, ukumboza, kanye nokugcina ukushisa

Ukuvikelwa kwemvelo kuyimpoqo, hhayi ngokuzithandela, kuma-electronics asendaweni eyingozi. Sikunikeza ngaphakathi ukuze kuklanywe njengengxenye yebhodi kunokuba kwengezwe ngumuntu wesithathu:

• Ukupheka — ukuvaleka okugcwele komshayeli noma izingxenye zamandla zokuvikela i-Ex m, ukumelana nokudlidliza, kanye nokuvalwa kokugqwala emsebenzini owodwa.
• Ukumboza okuhambisanayo — umswakama kanye nokuvikelwa kwegesi ebolile kwamabhodi angafakwanga ngokuphelele ebhodweni.
• Ukwakhiwa okungangenwa manzi futhi okuvalwe nge-value — ezindaweni eziyingozi ezimanzi noma ezimanzi, njengokusebenza kolwandle kanye nokudla/amakhemikhali.
• Ukugcinwa kokushisa — izinto zokuvikela kanye nendlela yokushisa yebhodi kuklanywe ndawonye ukuze ukubhodwela kungabambeli ukushisa futhi kusunduze isitsha siphume esigabeni saso sokushisa.

Ukuthola ukuphathwa kwe-potting kanye nokushisa kuhambisane kuyindlela yobunjiniyela yangempela, futhi ukwakha kokubili emgqeni ofanayo yindlela esigcina ngayo i-fixture ngaphakathi kwe-T-class yayo ngenkathi sivala ngokuphelele izinto zikagesi.

Abashayeli namabhodi kagesi asinda ensimini

Umshayeli uyingxenye engase inciphise kakhulu impilo yento enobungozi endaweni, ngakho sakha amabhodi omshayeli ngendlela egcinayo: ama-electrolytic angasebenzi kahle noma ezinye izindlela zokuphila isikhathi eside, ukulungiswa kwamandla okuqinile ukuze kuhambisane nezimboni, ukubekezelelana kokufaka okuningi kwamandla angazinzile endaweni, kanye nokuvikelwa kokukhuphuka okulinganiselwe kwendawo. Ngenxa yokuthi ukushisa komshayeli kubalwa ngokumelene nesigaba sokushisa sento, siyiklama ukuze ipholile ngaphakathi kwe-enclosure evaliwe kunokuba ibe semkhawulweni wesilinganiso sayo.

Lapho isixhumi sidinga ukusebenza okuphuthumayo, ibhethri kanye nezinto zokuvikela zakhiwe futhi zihlolwe ngezinga elifanayo lemvelo — akukho sizathu sokukhanya okuqinile okunebhodi elibuthakathaka ngaphakathi kwalo.

Amakhono e-PCB angaqhumi ngokushesha

Ithebula lifingqa lokho esikulethayo kumabhodi okukhanyisa anendawo eyingozi:
