PCB waxa loola jeedaa sabuurada wareegga daabacan (Printed circuit board), kaas oo ah bixiyaha xidhiidhka korantada ee qaybaha elektiroonigga ah.Waxay aad ugu badan tahay warshadaha elektiroonigga ah, waxaana si weyn loogu isticmaalaa saddex-xabag-dabiici ah (Rinji), mana jiro nooc ka mid ah koollada sida PCB-da saddex-caddaynta ah (rinji).Dhab ahaantii, lakabka koollada saddex-ceymiska ah (Rinjiga) ayaa lagu dahaadhay PCB-ga.rinji).
Codsashada saddex rinji waa in laga hortago in PCB-ga ay waxyeello u geystaan arrimo dibadda ah iyo horumarinta nolosha adeegga PCB.Maaddaama alaabada elektiroonigga ah ee dhamaadka-sare ay u leeyihiin shuruudo sare oo sarreeya tayada PCB-ga, dahaarka la jaan qaadaya ayaa si weyn loogu isticmaalaa looxyada wareegga.
Qodobbada si fudud u keena dhaawaca PCB:
Qoyaanka ayaa ah qodobka ugu wayn uguna badan ee burburiya PCB-yada.Qoyaanka xad-dhaafka ah wuxuu si weyn u dhimi doonaa iska caabbinta dahaarka ee ka dhexeeya kirishbooyada, dardar gelinta burburka, hoos u dhigida qiimaha Q, iyo daxaliyeyaasha kirishbooyada.Waxay badanaa dhacdaa in qaybta birta ee PCB ay leedahay patina, taas oo ay keento falcelinta kiimikada ee naxaasta birta leh uumiga biyaha iyo ogsijiinta.
Si la mid ah sida ay waxyeello u yihiin boqollaal wasakhaysan oo aad si bakhtiyaan ah uga heli karto sabuurada wareegga daabacan, waxayna keeni karaan natiijooyin la mid ah weerarka qoyaanka, sida cilladda elektiroonigga ah, daxalka kirishbooyada, iyo xitaa wareegyada gaaban.Wasakhowga inta badan laga helo hababka korantada waxa laga yaabaa inay yihiin walxo kiimiko oo ka hadhay habka wax soo saarka.Wasakhowgaan waxaa ka mid ah qulqulo, walxo sii daayo dareere, walxo bir ah, iyo qalin calaamadinta.
Waxa kale oo jira kooxo waaweyn oo wasakh ah oo ay sababaan gacmaha bini'aadamka, sida saliidda jidhka, faraha, waxyaalaha la isku qurxiyo iyo hadhaaga cuntada.Waxa kale oo jira wasakh badan oo ku jira deegaanka shaqada, sida buufinta milixda, ciid, shidaalka, aashitada, uumiga kale ee wasakhaysan iyo caaryada.
Waa maxay sababta loo mariyo saddex ka-hortagga koollada (Rinji)?
PCB-da oo lagu dahaadhay saddex anti-adhesive (Rinji) kaliya maahan qoyaan-celiya, boodhka-cakinta, iyo biyaha-ilaalinta, laakiin sidoo kale waxay leedahay caabbinta qabowga iyo kulaylka, caabbinta gabowga, caabbinta shucaaca, caabbinta milixda, iska caabbinta daxalka ozone, gariirka iska caabin, dabacsanaan wanaagsan iyo ku dheggan xooggan.Marka ay saameeyaan arrimo liddi ku ah deegaanka hawlgalka, waxay yarayn kartaa ama baabi'in kartaa hoos u dhaca waxqabadka hawlgalka elektaroonigga ah.
Iyada oo ay ugu wacan tahay jawiga codsiyada kala duwan ee alaabooyinka dhamaadka kala duwan, shuruudaha waxqabadka ee koollada waafaqsan ayaa la xoojin doonaa.Qalabka guriga sida qaboojiyaha, mashiinnada dharka lagu dhaqo, iyo kuleyliyeyaasha biyaha ayaa leh shuruudo sare oo u adkeysiga qoyaanka, halka marawaxadaha bannaanka iyo nalalka waddooyinka ay u baahan yihiin alaabo leh wax qabad heer sare ah oo ka hortagga ceeryaamo.
Sidee si dhakhso ah oo waxtar leh loogu dhejiyaa koollada waafaqsan (rinjiga) PCB?
Warshadaha wax-soo-saarka PCB-ga, waxaa jira qalab dhammaystiran oo si toos ah loogu dahaadho rinjiga ilaalinta ee looxyada wareegga - saddex mashiinnada rinjiga rinjiga, oo sidoo kale loo yaqaanno saddex mashiinnada rinjiga rinjiga ka-hortagga, saddex buufiyeyaasha rinji-ka-hortagga, saddex buufiyeyaasha saliidda-ka-hortagga. , Saddex mashiinnada buufinta rinjiga ka hortagga, iwm, ayaa loogu talagalay in lagu xakameeyo dareeraha, oo lagu daboolo lakabka rinjiga la jaan qaadaya dusha sare ee PCB-ga, sida daboolida lakabka sawir-celinta ee dusha PCB-ga iyadoo la gelinayo, buufinayo. ama dahaarka lafdhabarta.
Mashiinka dahaarka ee seddexda ah ayaa inta badan loo isticmaalaa buufinta saxda ah, dahaarka iyo daadinta xabagta, rinjiga iyo dareeraha kale ee habka wax soo saarka si loo gaaro booska saxda ah ee badeecad kasta, waxaana loo isticmaali karaa in lagu gaaro sawirka xariiqda, goobada ama arc.
Mashiinka dahaarka ee saddexda ah waa qalab buufin oo si gaar ah loogu talagalay buufinta saddex rinji.Maaddaama walxaha lagu buufinayo iyo dareeraha dareeraha lagu buufiyo ay kala duwan yihiin, xulashada qaybaha mashiinka dahaarka ee qaabka qalabka ayaa sidoo kale ka duwan.Mashiinka dahaarka ee saddexda ah ayaa qaata barnaamijkii ugu dambeeyay ee kantaroolka kumbuyuutarka, kaas oo xaqiijin kara isku xirka seddex geesoodka ah, wuxuuna ku qalabeysan yahay Nidaamka meelaynta kamaradku wuxuu si sax ah u xakameyn karaa aagga buufinta.
