Codsiga
Guddiga laba-geesoodka ah ayaa inta badan si ay u xalliyaan naqshadaynta adag ee wareegga wareegga iyo xaddidaadaha aagga, labada dhinac ee guddiga ayaa lagu rakibay qaybo, laba-lakab ah ama xargo-lakab ah. , amplifiers, hababka nalka, iyo muraayadaha baabuurta. PCB-yada laba-geesoodka ah ayaa ugu fiican codsiyada tignoolajiyada sare, wareegyada elektarooniga ah ee is haysta, iyo wareegyada adag. Codsigeedu aad buu u ballaadhan yahay, kharashkuna waa yar yahay.
FAQs
PCB-ga 2-lakabka ah waa naxaas ku dahaadhay labada dhinac oo dhexda ku yaal lakab dahaadh ah. Waxay leedahay qaybo ka mid ah labada dhinac ee looxa, taas oo ah sababta loogu yeero PCB-da laba-geesoodka ah. Waxa la hindisay iyada oo la isku daray laba lakab oo naxaas ah, oo ay dhexda ugu jirto walxo dielectric ah.
Waxaad qiyaasi kartaa waxa u dhexeeya farqiga muuqda ee u dhexeeya 2da lakab ee PCB iyo 4 lakab ee PCB sida magacyadoodu yihiin. 2 lakab PCB waxay leedahay raad laba dhinac ah oo leh lakab sare iyo hoose, halka 4 lakab ee PCB ay leedahay 4 lakab. Haddii aad si fiican u fahamto labada nooc ee looxyada PCB, waxaad ogaan doontaa inay jiraan farqi badan oo ku saabsan sida loo dhisay iyo sida loo shaqeeyo.
Raad-raacyada PCB-ga ee hal-dhinac ah ayaa ka jira hal dhinac oo keliya, halka PCB-yada laba-geesoodka ah ay leeyihiin raad labada dhinac ah oo leh lakabyo sare iyo hoose. Qaybaha iyo naxaasta korantada ah ayaa lagu rakibay labada dhinac ee PCB-ga laba-geesoodka ah, taasina waxay keenaysaa isgoysyada ama isku-dhafka raadadka.

The2 lakab PCB( PCB laba-geesood ah) waa loox wareeg ah oo daabacan oo naxaas ka dahaaran labada dhinac, sare iyo hoose. Dhexda waxaa ku yaal lakab dahaar ah, kaas oo ah looxa wareegga daabacan ee inta badan la isticmaalo. Labada dhinacba waxay noqon karaan qaabaynta iyo iibinta, taas oo si weyn u yaraynaysa dhibka qaabka, sidaas darteed si ballaaran ayaa loo isticmaalaa.
Si aad u isticmaasho wareegyada labada dhinac, waa in uu jiro xiriir sax ah oo ka dhexeeya labada dhinac. Buundooyinka u dhexeeya wareegyada noocaas ah waxaa loo yaqaan vias. Via waa dalool yar oo ku yaal guddiga PCB-ga oo laga buuxiyay ama lagu dahaadhay bir, kaas oo lagu xidhi karo wareegyada labada dhinac. Sababtoo ah aagga looxa laba-geesoodka ah wuxuu labanlaab ka weyn yahay midka hal-dhinac ah, guddiga laba-geesoodka ah wuxuu xalliyaa dhibaatada guddiga hal-dhinac ah sababtoo ah qaabka isku-dhafan (waxaa lagu xiri karaa dhinaca kale). iyada oo loo marayo godadka), waxayna ku habboon tahay wareegyada adag marka loo eego guddiga hal dhinac ah.
Waxaan u baahanahay badeecooyin elektaroonik ah oo leh waxqabad sare, cabbir yar, iyo shaqooyin badan, taas oo kor u qaadeysa horumarinta wax soo saarka guddiga wareegga daabacan si ay u noqoto iftiin, khafiif ah, gaaban, iyo yar. Meel xaddidan, hawlo badan ayaa la xaqiijin karaa, cufnaanta qaabeynta ayaa noqotey mid weyn, dhexroorka daloolkuna wuu yar yahay. Dhexroorka daloolka ugu yar ee awoodda qodista farsamada ayaa hoos uga dhacday 0.4mm ilaa 0.2mm ama xitaa ka yar. Dhexroorka daloolka PTH ayaa sii yaraanaya oo sii yaraanaya. Tayada PTH (Plated through Hole) kaas oo isku xirka lakabka-ilaa-lakabka ay ku xiran tahay waxay si toos ah ula xiriirtaa kalsoonida guddiga wareegga daabacan.
