1. Hordhac
Gudiga soo bandhigga ee caadiga ahi waxay leeyihiin difaac daciif ah oo ka dhan ah qoyaanka, biyaha, iyo boodhka, oo inta badan la kulma arrimaha soo socda:
Ⅰ. Bey'adaha qoyan, dufcadaha waaweyn ee pixels dhintay, nalal jabay, iyo "dirsiartar" ifafaale "ifafaale ayaa badanaa dhaca;
Ⅱ. Inta lagu gudajiro isticmaalka muddada-dheer, hawo-mareenka qaboojinta iyo biyaha dillaaca ayaa ku dhufan kara gadhka laambada;
Ⅲ. Ururinta boodhka ee shaashadda ayaa horseedaysa in kuleylka liita ee kuleylka ah iyo da 'da' oo da 'ah.
General Gudaha Gudaha ee Gudaha, looxyada hogaamiya ayaa badanaa lagu gaarsiiyaa gobolka khaladka eber ee warshadda. Si kastaba ha noqotee, ka dib muddo adeegsi ah, arrimaha sida nalalka jabay iyo iftiinka dhalaalka ayaa inta badan dhaca, iyo isku dhacyada ula kac ah waxay sababi karaan dhibcaha nalalka. Goobaha rakibaadda, jawiga aan la fileynin ama jawiga hoosaadku mararka qaarkood waa lala kulmi karaa, sida cilado waaweyn oo ay ka dhalato kala duwanaanshaha heerkulka ee tooska ah, ama qoyaan aad u badan oo sababa kororka cilad ciladaha shaashadda.
Gudaha gudahaGawaarida ganaaxyada ee wanaagsanBixiyeyaasha leh kormeerka sanadlaha ah ee sanadlaha ah, wax ka qabashada arrimaha sida qoyaanka, boodhka, iyo sicirka qaladka, iyo hagaajinta tayada sheyga ee culeyska iyo kharashka waa walaac muhiim u ah alaab-qeybiyeyaasha soo bandhigaya.
Jaantus 1. Xadhig gaagaaban oo gaagaaban iyo sadarka iftiinka iftiinka
2. Xalka dahaarka ah ee ab
Si wax ku ool ah wax looga qabto arrimahaan,La gartaywaxay soo bandhigaysaa aOB (adverting toptic-ka indhaha) xalka dahabka. Shaashadaha Tiknolojiyada Tiknolojiyada ee Tooska tikniyoolajiyada ayaa ka go'ay tuubooyin la xidhiidha miisaska kiimikada dibedda, ka hortagga qoyaanka iyo fara gelin-ku-filnaanshaha, si weyn kor loogu qaadayo waxqabadka difaacaShaashadda hogaaminaya.
Xalkani wuxuu ku saleysan yahay habka wax soo saarka ee soosaarka ee LED-ka ee hadda lagu soo rogay, oo si aan kala sooc lahayn u dhexgalo SMT jira (Tilmaamaha Broonka ee Kormaridda) Khadadka waxsoosaarka.
Jaantus 2. Jaantus Nidaamka Qeerka Duurka dusha sare (dusha sare)
The specific process is as follows: after the LED boards are made using SMT technology and aged for 72 hours, a coating is applied to the board surface, forming a protective layer that encases conductive pins, insulating them from moisture and vapor effects, as shown Jaantuska 3.
Si aad u soo bandhigto alaabooyinka soo bandhigaya oo leh heerar ilaalin ah oo ah IP40 (IPXX) waxay muujineysaa booqashada boodhka, iyo tikniyoolajiyadda dahabka si wax ku ool ah oo kor u qaadaya heerka sare ee nalka, waxay ka hortageysaa iftiinka shilka. , waxayna yareysaa heerka ciladaha guud ee shaashadda (PPM). Xalkani wuxuu la kulmay baahida suuqa, oo ku bislaaday wax soo saarka, oo aan si xad dhaaf ah u kordhin qiimaha guud.
Jaantus 3. Jaantus Nidaamka Nidaamka ah ee geedi socodka dusha sare
Intaa waxaa sii dheer, habka ilaalinta ee ku saabsan dhabarka PCB (guddiga wareejinta ee daabacan) waxay ilaalinaysaa hab saddex-geesood ah oo ka-hortag rinji saddex-cudur ah, hagaajinta heerka ilaalinta ee gadaasha guddiga wareegga iyada oo loo marayo hanaan ku-buufin. Lakab ilaalin ah ayaa lagu sameeyaa dusha isku-dhafka ah ee isku-dhafka ah (IC) dusha sare, ka hortagga fashilka qaybaha isku-dhafan ee isku-dhafka ah ee wareegga wadista wareega.
3. Falanqaynta astaamaha AOB
3.1 Guryaha ilaalinta jirka
Astaamaha difaaca jirka ee AOB waxay ku tiirsan yihiin daboolka buuxinta ee salka ku haya, oo leh astaamo isku xira oo la mid ah tallee-ga, waa wax lagu daro. Qulqulkan oo dhameystiraya oo dhan oo dhan ee hogaaminaya, kordhinta awoodda xiriirka ee u dhexeeya hogaamiyaha iyo PCB. Imtixaanada shaybaarka ayaa muujinaya in kooxda 'Smart-ka' ee caadiga ah ee 'SMT-ka' ee 'SMT-ka' ay tahay 1kg, halka xalka Aob, uu ku guuleysto awoodda isku dhaca inta lagu guda jiro rakibida iyo ka-goynta xaafadaha ku keenaya boodhka laamiga ah inay noqdaan kuwo aan la arki karin.
3.2 Guryaha Ilaalinta kiimikada kiimikada
Aroobyada Ilaalinta kiimikada ee AOB waxay ku lug leedahay lakab difaac oo hufan oo sahlayaal ah oo awood u leh in la isticmaalo iyada oo la adeegsanayo walxaha sareeya oo lagu dabaqayo tikniyoolajiyadda nanoaco. Ku adkaanta lakabkan waa 5 ~ 6h oo ku saabsan cabirka MoohS, oo si wax ku ool ah u xannibaya qoyaanka iyo boodhka, hubinta in laambada ay si xun u saameeyaan bey'ada inta lagu jiro isticmaalka.
3.3 Soo-hubinta cusub ee ku xusan guryaha difaaca
3.3.1 Kordhinta xagal daawasho
Lakabka difaaca daahfurka ee Matte wuxuu u shaqeeyaa sidii muraayad horteeda horteeda, kordhinta xagasha iftiinka iftiinka ee laambada iftiinka. Imtixaanaadka ayaa muujinaya in xagasha iftiinka iftiinka laga soo kordhayo laga bilaabo 140 ° illaa 170 °.
3.3.2 Hagaajinta iftiinka iftiinka
Qalabka dusha sare ee SMD-ka ayaa tilmaamaya ilo iftiin leh, kuwaas oo ah kuwa aad u sarreeya marka loo eego ilaha iftiinka dusha sare. Daboolaadka AOB wuxuu ku darayaa lakab galaas oo galaas oo hufan oo ku saabsan dhulalka SMD, yareynta granralation-ka iyada oo la adeegsanayo iyada oo la adeegsanayo iyo jimicsiga, yareynta saamaynta moorsida, iyo kor u qaadista isku-darka iftiinka.
3.3.3 shaashad madow oo joogto ah
Midab aan la is waafajin karin ee kooxda PCB-ga ayaa had iyo jeer dhibaato ku ahaa bandhigyada SMD. Tiknolojiyadda AOB Daboolista ayaa xakameyn kara dhumucda iyo midabka lakabka dahaarka, si wax ku ool ah u xallin kara arrinta midabyada la-taliyayaasha ee PCB-da iyada oo aan laga soo bixin arrinta arrinta, iyo hagaajinta hufnaanta shixnadaha.
3.3.4 Isbarbardhiga kordhay
Naaguhu wuxuu u oggolaanayaa xakameyn sax ah, oo leh walxaha la xakameynayo, kordhinta madow ee midabka salka shaashadda iyo hagaajinta isbarbardhiga.
4. Gunaanad
Tiknolojiyadda AOB Daboolista oo wasakhaysan oo ku saabsan biinanka korantada ee soo if-baxa, si wax ku ool ah looga hortago ciladaha ay sababaan qoyaan iyo boodh, intaad siinayso difaac isku dhac. Iyada oo la kaashanayo go'doominta ee loonoob nanococation, heerarka ciladaha ee hogaaminta waxaa laga dhimi karaa ka hooseeya 5ppm, si weyn u wanaajinta dhalidda shaashadda iyo isku halaynta.
Waxaa lagu dhisay aasaaska SMD LED, geedi socodka AOB wuxuu dhaxal ku yahay dayactirka dayactirka laambada ee SMD, halka ay si buuxda u hagaajinayso iyo isku haleecida saameynta isticmaalaha, heerka ilaalinta, iyo heerka nalka dhimashada. Soo bixitaanka Aob wuxuu bixiyaa xulasho tijaabo ah oo ku saabsan xalka gudaha ee ku saabsan xalka gudaha ee gudaha oo ah horumar weyn oo ku saabsan isbeddelka tikniyoolajiyadda shaashadda ee hogaamineysa.
Kula mid ah smble-caddeyn cusub oo gudaha ahSariirta yar yar ayaa soo bandhigtay- Biyo-celintuprof, oo ah caddeyn iyo caddeyn ku-dhafan - ab bandhig.Nala soo xiriirsi loo helo kootada rasmiga ah.
