Doorashada saxda ahPCB (Guddiga Wareega Daabacan)si loo waafajiyo aLCD (Muuqaal Crystal ah oo dareere ah)waxay ku lug leedahay dhowr tixgalin oo muhiim ah si loo hubiyo iswaafajinta iyo waxqabadka ugu fiican. Waa kuwan hage-talaabo-tallaabo ah oo kaa caawin doona habka aad u marayso:
1. Faham Tilmaamaha LCD-gaaga
Nooca Interface: Go'aami nooca is-dhexgalka ee LCD-gaagu isticmaalo, sida LVDS (Casaas ka duwanaanshaha Voltage-hoose), RGB (Casaan, Cagaar, Buluug), HDMI, ama kuwa kale. Hubi in PCB-gu uu taageeri karo interface-kan.
Xallinta iyo Cabbirka: Hubi xallinta (tusaale, 1920x1080) iyo cabbirka jireed ee LCD-ga. PCB-ga waa in loo qaabeeyey si uu u maareeyo xallinta gaarka ah iyo habaynta pixel.
Shuruudaha Korontada iyo Korontada: Xaqiiji tamarta iyo shuruudaha korontadaGuddi LCD ahiyo iftiinka danbe. PCB-gu waa inuu lahaadaa wareegyada sahayda korontadu ku habboon tahay si ay shuruudahan u dhigmaan.
2. Dooro kantaroolka saxda ah IC
Waafaqsanaan: Hubi in PCB ay ku jirto kontaroolaha IC kaas oo la socon kara caddaymaha LCD gaaga. Xakameeyaha IC waa inuu awood u leeyahay inuu maareeyo xallinta LCD-ga, heerka cusbooneysiinta, iyo is-dhexgalka.
• Astaamaha: Tixgeli sifooyin dheeri ah oo aad u baahan karto, sida is-dheellitiran ku dhex-jirsan, hawl-qabadka shaashadda (OSD), ama sifooyinka maamulka midabka gaarka ah.
3. Hubi qaabka PCB-ga
Waafaqsanaanta Xidhiidhiyaha: Hubi in PCB-gu leeyahay xidhiidhiyeyaasha saxda ah ee guddida LCD. Hubi in pinout-ka iyo noocyada isku xidhaha ay ku habboon yihiin interface-ka LCD.
• Dariiqa Signal: Xaqiiji in qaabka PCB-gu uu taageerayo hab-socodka saxda ah ee xogta LCD-ga iyo xadadka xakamaynta. Tan waxaa ka mid ah hubinta ballaadhka raadadka iyo dariiqa si looga hortago arrimaha hufnaanta isha.
4.Dib-u-eegis Maareynta Awoodda
Naqshadaynta Korontada: Hubi in PCB ay ku jirto wareegyada maaraynta korantada ee ku habboon si ay u siiso tamarta lagama maarmaanka u ah labadabaLCDiyo iftiinkeeda danbe.
• Xakamaynta iftiinka dambe: Haddii LCD-gu isticmaalo nalka dambe, hubi in PCB-gu leeyahay wareegyo ku habboon xakamaynta iftiinka iyo iftiinka iftiinka dambe ee iftiinka.
5.Tixgeli Arrimaha Deegaanka
Heerkulka Heerkulka: Hubi in PCB-gu uu ku shaqayn karo inta u dhaxaysa heerkulka looga baahan yahay codsigaaga, gaar ahaan haddii loo isticmaali doono meelo adag.
• Waarta: Haddii LCD-ga loo isticmaali doono xaalado qallafsan, hubi in PCB-ga loogu talagalay inuu u adkaysto walbahaarka jirka, gariirka, iyo soo-gaadhista suurtagalka ah ee walxaha.
6.Dib-u-eegis Dukumentiyada iyo Taageerada
• Xaashiyaha xogta iyo buug-gacmeedyada: Dib u eeg xaashida xogta iyo buug-gacmeedyada LCD iyo PCB-ga labadaba. Hubi inay bixiyaan macluumaadka lagama maarmaanka u ah is-dhexgalka iyo cilad-baadhista.
• Taageerada Farsamada: Tixgeli helitaanka taageerada farsamada ee soo saaraha PCB ama alaab-qeybiyaha haddii aad la kulanto arrimo inta lagu jiro isdhexgalka.
7.Prototype iyo Imtixaan
• Dhis Prototype: Kahor intaadan samayn naqshad kama dambays ah, dhis prototype si aad u tijaabiso la dhexgalka LCD-ga PCB-ga. Tani waxay gacan ka geysaneysaa in la aqoonsado oo la xalliyo arrimaha suurtagalka ah.
Si fiican u tijaabi: Hubi arrimaha sidabandhigartifacts, saxnaanta midabka, iyo waxqabadka guud. Hubi in PCB iyo LCD ay u wada shaqeeyaan si aan kala go 'lahayn.
Habka Tusaalaha:
1.Go'aami Interface-ka LCD-ga: Kasoo qaad in LCD-gaagu isticmaalo interface LVDS oo leh 1920x1080 xallin.
2.Dooro Guddi Koontarool oo Wanaagsan: Dooro aPCBoo leh kontaroolaha LVDS IC kaas oo taageera 1920x1080 xallinta oo ay ku jiraan xiriiriyeyaasha habboon.
3.Verify Power Requirements: Hubi wareegyada korantada PCB si aad u hubiso inay ku haboon yihiin koronta LCD iyo baahida hadda.
4. Dhis oo Tijaabi: Isku-dubarid qaybaha, ku xidh LCD-ga PCB, oo tijaabi muujinta saxda ah ee shaqeynta iyo waxqabadka.
Markaad si taxadar leh u tixgeliso arrimahan, waxaad dooran kartaa aPCBkaas oo u dhigma shuruudaha LCD-ga oo hubiya waxqabadka bandhiga oo la isku halayn karo oo tayo sare leh.
Hal qayb oo ka mid ah DIEN Electronics Co., Ltd.oo la aasaasay 2020, waa bandhig LCD ah oo xirfad leh, Taabasho taabasho iyo Taabasho taabasho soo saaraha xalalka kuwaas oo ku takhasusay R&D, heerka wax soo saarka iyo suuq-geynta iyo LCD-ga loo habeeyey iyo alaabada taabashada. Alaabadayada waxaa ka mid ah guddiga TFT LCD, module TFT LCD oo leh shaashad taabashada capacitive iyo iska caabin ah (taageerada isku xirnaanta indhaha iyo isku xirnaanta hawada), iyo guddiga kontoroolka LCD iyo guddiga kontoroolka taabashada, bandhig warshadeed, xalka bandhigga caafimaadka, xallinta PC-ga warshadaha, xallinta muuqaalka caadada,guddiga PCBiyoguddiga xakamayntaxal.
