Wareegyada Pandawill waxay bixiyaan aluminium qiimo jaban iyo guddiga wareegga qalabka FR4 ee nalka LED & codsiyada muujinta LED.
Waxaa loo isticmaalaa:
Nalalka xariijinta ganacsiga
Nalalka baabuurta
Codsiyada badda
Codsiyada dhismaha
Gadiidka / Calaamadaha Wadada
Isboorrada / shaashadaha fiidiyowga iwm
Iyadoo in ka badan 10 sano ay ku jiraan PCB-yada LED-ka, waxaan awood u leenahay inaan soo bandhigno xulashada ugu fiican ee qalabka, dhameystirka iibka iyo miisaanka naxaasta si loo daboolo loona dhaafo waxqabadka iyo heerarka kalsoonida muddada-dheer ee looga baahan yahay teknoolojiyada ku saleysan LED-ka. Habka Pandawill ee ku wajahan codsiyada nalalka LED wuxuu diiradda saaraa dhinac kasta oo ka mid ah naqshadeynta iyo iskuxirka guddiga wareegga.
1. Qalab noocee ah ayaa ganacsi ahaan faa'iido leh oo bixiya isla ama ka sii sareeya faahfaahin qiimo jaban?
2. Sidee baa loox loox u sameeyaa si loo abuuro wax soo saarka ugu badan ee guddiga wax soo saarka?
3. Sidee loo adeegsadaa dariiqa iyo gooldhalinta si looxakameeyo looxyada si loogu bixiyo adkeyn balaaran guddiga waxsoosaarka isla markaana loo yareeyo qadarka shaqada dhammeynta kadib?
4.Waa kuwee dhammeystirka dusha sare ee bixiya waxqabadka ugu fiican ee nidaamkaaga magacaabista golaha.
5.Waa maxay miisaanka saxda ah ee naxaasta ah ee bixin doona kalsoonida muddada-dheer ee loo baahan yahay si loo waafajiyo nolosha laga filayo sheyga iftiinka LED-ka.
6. Midab noocee ah, dhammayn ah (dhalaalaya ama jilicsan) iyo qeexida wax iska caabinta alxanka waa in loo isticmaalaa si loo nuugo oo loo kala diro xaddiga ugu badan ee iftiinka / kuleylka, ama la ilaaliyo dhalaalka cad si looga iftiimiyo iftiinka sida ugu macquulsan ee suurtogalka ah iyadoo aan midab lahayn?
7. Tayada shaashadda xariirta iyo dhammeystirka si tilmaamaha rakibayaasha iyo soo-saarista badeecadda si dhammaystiran loo soo bandhigo.
Bir Xudunta PCB
Mashiinka Aaladda Daabacan ee Birta ah (MCPCB), ama PCB-da kuleylka leh, waa nooc PCB ah oo leh wax bir ah oo saldhig u ah qaybta kuleylka kuleylka ee guddiga. Ujeedada udub dhexaadka MCPCB waa in kuleylka laga weeciyo qaybaha muhiimka ah ee guddiga iyo meelaha muhiimka u ah sida taageerada birta ee birta ama xudunta birta ah. Biraha hoose ee MCPCB waxaa loo adeegsadaa bedel ahaan looxyada FR4 ama CEM3.
Qalabka PCB-ga Birta ah iyo dhumucdiisuna
Xudunta birta ee PCB-da kuleylka waxay noqon kartaa aluminium (aluminium udub dhexaad u PCB), naxaas (PCB naxaas kobbar ah ama PCB naxaas culus) ama isku dar ah aalado gaar ah. Tan ugu caansan waa aluminium asaasiga ah PCB.
Dhumucda udub dhexaadka biraha ee taarikada saldhigga PCB caadi ahaan waa 30 mil - 125 mil, laakiin taarikada qaro weyn iyo dhuuban ayaa suuragal ah.
MCPCB dhumucda bireed copper waxay noqon kartaa 1 - 10 oz.
Faa'iidooyinka MCPCB
MCPCBs waxay faa'iido u yeelan karaan inay u adeegsadaan awooddooda inay dhexgalaan lakabka polymer dielectric oo leh hago kuleyl sare oo iska caabin ah kuleylka hoose.
PCB-yada muhiimka u ah birta waxay wareejiyaan kuleylka 8 ilaa 9 jeer ka dhaqso badan FR4 PCBs. MCPCB waxay dahaarisaa kuleylka faafiya, haynta kuleylka dhaliya qaybaha qaboojiyaha taasoo keenta waxqabad kordha iyo nolosha.
