Dib u soo dhawoow, kuwa farsamada jecel iyo kuwa xiiseeya DIY! Maanta, diiraddayadu waxay saaran tahay looxyada PCB, taas oo ah, looxyada wareegyada daabacan. Qaybahan yaryar laakiin muhiimka ah ayaa udub dhexaad u ah inta badan aaladaha elektiroonigga ah waxayna mas'uul ka yihiin hubinta shaqadooda saxda ah. Haddii aad tahay injineer xirfadle ah ama hiwaayad-yaqaan ah, ogaanshaha sida loo kormeero guddiga PCB-ga ayaa muhiim u ah cilad-bixinta iyo ilaalinta qalabka korontada. Haddaba, aan u dhex galno tillaabooyinka lagama maarmaanka ah si aan u tijaabino oo aan u hubinno kalsoonida guddiga PCB!
1. Kormeer muuqaal ah:
Talaabada ugu horeysa ee lagu baaro PCB waa in la sameeyo kormeer muuqaal oo dhamaystiran. Ka hubi sabuuradda wareegga wixii dhaawac jidheed ah, sida daxalka, qaybaha gubtay, ama xidhiidhada dabacsan. Hubi calaamadaha jabka ama burburka, qaybaha khaldan, ama calaamadaha kulaylka. Kormeerka muuqaalku wuxuu u ekaan karaa mid fudud, laakiin waxay kaa caawin kartaa si wax ku ool ah loo ogaado dhibaatooyinka iman kara.
2. Kormeerida qaybaha:
Kormeerka muuqaalka ka dib, sii wad si aad u hubiso qayb kasta oo ku jirta sabuuradda PCB. Ku bilaw inaad hubiso in dhammaan qaybaha la rakibay, la toosiyay, oo si sax ah loo iibiyay. Isticmaal multimeter si aad u cabbirto iska caabinta iyo sii wadida capacitors, resistors, iyo qaybaha kale ee korantada. Fiiro gaar ah u yeelo qaybaha u nugul fashilka, sida capacitors leh dusha sare ama iska caabiyeyaasha gubanaya.
3. Awoodda imtixaanka:
Marka kormeerka aragga iyo baadhista qaybtu dhammaato, waa waqtigii la samayn lahaa tijaabada awoodda. Ku xidh guddiga PCB il awoodeed oo la isku halayn karo iyadoo loo eegayo qeexida soo-saaraha. La soco Motherboard-kaaga hab-dhaqan aan caadi ahayn, sida kulaylka badan, sigaarka, ama xidhitaanka degdega ah. Fadlan ka digtoonow inaadan taaban wax kasta oo ka kooban inta boodhka uu shidan yahay, maadaama korontadu ay keeni karto khatar naxdin leh.
4. Tijaabada ishaarada:
Marka lagu daro tijaabinta korontada, calaamadaha la soo diro oo ay helaan guddiga PCB waa in sidoo kale la hubiyaa. Isticmaal oscilloscope si aad ula socoto calaamadaha wax soo saarka iyo heerarka danabka oo aad barbar dhigtid tilmaamaha loo baahan yahay. Hubi in ishaadu ay degan tahay iyada oo aan wax qallooc ah ama isbedbeddel ahi jirin. Tallaabadani waa mid muhiim ah, gaar ahaan looxyada PCB ee adag halkaasoo qaybo badan ay is dhexgalaan.
5. Tijaabada shaqaynaysa:
Si loo hubiyo waxqabadka saxda ah ee guddiga PCB, waxaa muhiim ah in la sameeyo baaritaan shaqeynaya. Ku xidh looxa qalabka ku habboon ee uu ku shaqaynayo, sida matoorka ama dareeraha. Hubi in guddiga PCB-gu uu si sax ah u guto shaqadii loogu talagalay. Xaqiiji in xidhiidhada wax-soo-saarka ahi ay sax yihiin iyo in dhammaan shaqayntu ay u shaqeyso sidii la filayey. Tallaabadani waxay u baahan kartaa qalab aad u horumarsan sida falanqeeyaha macquulka ah ama koronto dhaliyaha shaqada, iyadoo ku xiran kakanaanta guddiga PCB.
Hambalyo! Markaad raacdo tillaabooyinka kore, waxaad baratay sida si wax ku ool ah loo hubiyo shaqeynta iyo waxqabadka guddiga PCB-gaaga. Xusuusnow, tijaabada saxda ah waxay muhiim u tahay hubinta in qalabkaaga elegtarooniga ahi u shaqeeyo si habsami leh oo la isku halleyn karo. Haddi arintu soo baxdo inta lagu jiro tijaabada, fahamka sababta asalka ah ayaa ah talaabada ugu horeysa ee lagu xalinayo dhibaatada. Haddii ay dhacdo dhaawac daran ama arrimo kakan, ka raadso caawimo xirfad leh khubarada PCB ama farsamayaqaannada dayactirka qalabka elektaroonigga ah isla markiiba. Aad u fiirso, sii wad waxbarashada, oo ku raaxayso tijaabooyinka guddiga PCB!
