Codsiga

PCB-daloollada nuska ah waxa loola jeedaa qodista labaad iyo habka qaabaynta ka dib markii godka kowaad la qoday, iyo ugu dambeyntii kala bar godka birta ah ayaa loo hayaa.Ujeedada ayaa ah in si toos ah loo dhufto cidhifka godka cidhifka ugu weyn si loo badbaadiyo isku xirka iyo booska, oo inta badan ka muuqda wareegyada calaamadaha.
Looxyada wareegga nus-dalool ayaa inta badan loo isticmaalaa in lagu dhejiyo qaybaha elektiroonigga ah ee cufnaanta sare leh, sida aaladaha mobilada, saacadaha smart, qalabka caafimaadka, qalabka maqalka iyo muuqaalka, iwm. oo ka hufan.

Daloolka nuska ah ee aan dahaadhka ahayn ee cidhifyada PCB-ga waa mid ka mid ah walxaha naqshadaynta ee sida caadiga ah loo isticmaalo geeddi-socodka wax-soo-saarka PCB-ga, shaqadeeda ugu weyni waa hagaajinta PCB-ga.Habka wax-soo-saarka guddiga PCB-ga, adigoo ka tagaya godadka kala bar meelaha qaarkood ee cidhifka guddiga PCB-ga, guddiga PCB waxaa lagu hagaajin karaa qalabka ama guriga oo leh boolal.Isla mar ahaantaana, inta lagu guda jiro habka isu-ururinta guddiga PCB, daloolka nuska ah wuxuu kaloo caawiyaa in la dhigo oo la isku toosiyo guddiga PCB si loo hubiyo saxnaanta iyo xasilloonida alaabta ugu dambeysa.

Daloolka nuska ah ee lagu dhejiyay dhinaca guddiga wareegga waa in la hagaajiyo isku halaynta isku xirka dhinaca guddiga.Caadi ahaan, ka dib marka guddiga wareegga daabacan (PCB) la gooyo, lakabka naxaasta ah ee daboolan ee cidhifka ayaa soo muuqan doona, kaas oo u nugul oksaydhka iyo daxalka.Si loo xaliyo dhibaatadan, lakabka naxaasta waxaa inta badan lagu dahaadhay lakabka ilaalinta by electroplating cidhifka guddiga galay god nus ah si loo hagaajiyo ay iska caabin ah oksaydhka iyo iska caabinta daxalka, iyo waxa ay sidoo kale kordhin kartaa aagga alxanka iyo hagaajinta isku halaynta isku xirka.

Inta lagu jiro habka farsamaynta, sida loo xakameeyo tayada alaabta ka dib samaynta godadka semi-metalized ee cidhifka looxa, sida qodxaha naxaasta ah ee derbiga daloolka, iwm, had iyo jeer waxay ahayd dhibaato adag habka wax soo saarka.Looxa noocan oo kale ah oo leh saf dhan oo godad bir bir ah ka samaysan ayaa looxa PCB waxaa lagu gartaa dhexroorka dalool yar, waxaana inta badan loo isticmaalaa guddiga gabadha ee guddiga hooyada.Daloolladaas, waxa lagu wada alxanayaa looxa hooyada iyo biinanka qaybaha.Marka la iibinayo, waxay u horseedi doontaa alxanka daciifka ah, alxanka beenta ah, iyo isku xirka gaaban ee dhexda labada biin.

FAQs

1.Waa maxay ujeedada godka nuska ah ee la dhejiyay?

Waxaa laga yaabaa inay faa'iido leedahay in la dhigo godad dhejisan (PTH) geesaha looxa.Tusaale ahaan marka aad rabto in aad laba PCB's ku iibiso xagal 90° ah ama marka aad PCB ka iibinayso daasad bir ah.

2.Waa maxay alaabta sida caadiga ah loo isticmaali karaa?

Tusaale ahaan, isku-darka modules-ka-koontarool ee adag ee PCB-yada caadiga ah, si gaar ah loo qorsheeyay.Codsiyada dheeraadka ah ayaa la soo bandhigay, HF ama modules dhoobada kuwaas oo lagu iibiyo sabuuradda wareegga daabacan ee saldhigga ah.

Habka wax soo saarka 3.PCB ee daloolka nuska ah ee dhejiyay

Qodista- dalool lagu dahaadhay (PTH) - dahaadhid guddi - wareejinta sawirka - dajinta hannaankii -pth nuska daloolka - xariijimaha - etching - maaskaro alxan - silkscreen - daaweynta dusha.

4.Waa maxay cabbirka godka nuska ah ee PTH ayaa loo baahan yahay?

1. Dhexroorka ≥0.6MM;

2. Masaafada u dhaxaysa cidhifka daloolka ≥0.6MM;

3. Baaxadda giraanta etching waxay u baahan tahay 0.25mm;

5. Maxay ugu baahan tahay lacag dheeraad ah PCB-ga nuska godka ah?

God nusku waa hannaan gaar ah.Si loo hubiyo in ay jirto naxaas godka ku jira, waa in ay marka hore wax shiiddo ka hor inta aan la dhigin habka naxaasta.PCB-ga guud ee godka nusku aad buu u yar yahay, markaa qiimihiisa ayaa ka qaalisan PCB-ga caadiga ah.
