Cawaaqibta ka dhalan karta kala dheeraynta cidhifka ka kooban-ilaa-board; Aaladaha aadka ugu dhow cidhifka ayaa laga yaabaa inay farageliyaan shaqada qalabka isku-ururinta otomaatiga ah, sida mashiinnada alxanka ee mowjada ama dib u qulqulaya. Aaladaha aad ugu dhow cidhifka ayaa laga yaabaa in ay waxyeelo soo gaarto inta lagu guda jiro muraayadda looxa dhamaadka habka wax soo saarka. Tani waxay […]

Waa maxay sababta PCB-yada loogu baahan yahay in la hagaajiyo? PCB-yada waxaa la isugu keenay si ay u buuxiyaan shuruudaha wax soo saarka. Qaar ka mid ah looxyada PCB aad bay u yar yihiin si ay u buuxiyaan shuruudaha ku habboon, markaa waxay u baahan yihiin in la isu keeno si wax soo saarka. Si loo hagaajiyo waxtarka alxanka ee SMT. Kaliya waxaad u baahan tahay inaad marto SMT hal mar si aad u dhamaystirto alxanka

Waa maxay god-in-pad? Daloolka saxanka waxaa loola jeedaa godka suufka, suufka loogu talagalay saxanka SMD, badanaa wuxuu tixraacaa 0603 iyo wixii ka sareeya SMD iyo BGA pads, oo badanaa loo yaqaan VIP (via in pad). Daloollada suufka ah laguma magacaabi karo dalool saxanka, sababtoo ah godadka fur-in

Waligaa ha dhayalsan PCB-da-godka nuska ah Waa maxay PCB-dad-god? Fiisooyin badhkood waa godadka godadka laga qoday ee ku teedsan xuduudaha PCB ee ujeedooyinka wax soo saarka. Marka godadka lagu dhejiyo naxaas, geesaha waa la gooyaa si godadka ku yaal xadka ay kala badh u noqdaan. Cidhifyada PCB-gu waxay u egyihiin mid la dahaadhay

Hordhac: Qaabka adag ee PCB-ga naqshadaynta iyo habka wax-soo-saarka falanqaynta wax-soo-saarka DFM ayaa si gaar ah muhiim u ah. Naqshadeynta DFM ee Wax-soo-saarka, Naqshad wax-soo-saarka (DFM) Doorka DFM waa horumarinta habka wax-soo-saarka alaabta. Maanta DFM waa tignoolajiyada udub-dhexaadka u ah injineernimada isbarbar-dhigga, sababtoo ah naqshadeynta iyo wax-soo-saarka ayaa ah labada xiriir ee ugu muhiimsan nolosha badeecada.

Waa maxay BOM? Faham fudud ayaa ah: liiska qaybaha elektaroonigga ah, alaabtu waxay ka kooban tahay qaybo badan, oo ay ku jiraan: looxyada, capacitors, resistors, diodes, crystals, inductors, chips driver, microcontrollers, chips power power, step up and step-down chips, chips LDO, chips memory, connectors, pins, safs of mother, iwm. Injineerada ayaa ku salaysnaan doona

Sidee loo Hubiyaa Naqshadeynta Kalsoonida ee Alaabta Elektarooniga ah? Waa maxay Naqshadeynta Wax-soo-saarka? Naqshadeynta urability-soo-saarka , Hadda laga bilaabo tirinta bilawga furan Tijaabi ka fiirso badeecada nidaamka samayn kara galmada , hagaajinta heerka gudbinta badeecada iyo isku halaynta , Ka dhigaysa badeecada mid fudud in la soo saaro iyadoo la dhimayo kharashyada wax soo saarka. Naqshadaynta loogu talagalay

Sidee Looga Fogaadaa Godad Daloolo Yaryar Iyo Godadka Ku Jira Biinanka Qalabka? Guddiga PCB ee biinanka aaladda fur-in waxay u baahan yihiin in la dalooliyo si loo geliyo aaladda, qodista PCB waa habka samaynta saxanka PCB, sidoo kale waa tallaabo aad muhiim u ah. Inta badan godadka looxa, toosinta waxay u baahan tahay inay ciyaaraan dalool, qaabdhismeedku wuxuu u baahan yahay
