9. Waa maxay xalin?Jawaab: Meel fog oo ah 1mm, xallinta xadhkaha ama xariiqyada kala fogaanshaha ee ay samayn karaan iska caabinta filimka qalalan ayaa sidoo kale lagu muujin karaa cabbirka buuxda ee xadadka ama kala dheereynta.Farqiga u dhexeeya filimka qalalan iyo dhumucda filimka iska caabinta Dhumucda filimka polyester-ka ayaa la xidhiidha.Lakabka filimka iska caabinta ah ee dhumucdiisuna way sii yaraanaysaa xallinta.Marka iftiinka...
- Dhamaystirka dusha sare ee PCB, faa'iidooyinka iyo khasaarooyinka
Qof kasta oo ku lug leh warshadaha guddiga wareegga daabacan (PCB) wuxuu fahmayaa in PCB-yadu ay leeyihiin naxaas dhammays tiran oo korkooda ah.Haddii aan la ilaalin markaa naxaastu way oksaydhaysaa oo way xumaanaysaa, taasoo ka dhigaysa looxa wareegga mid aan la isticmaali karin.Dhammaystirka dusha sare waxa uu sameeyaa is-dhexgal muhiim ah oo u dhexeeya qaybta iyo PCB-ga.Dhammaystirka wuxuu leeyahay laba hawlood oo muhiim ah, si loo ilaaliyo wareegga naxaasta ee bannaan iyo t ...
- A&Q ee PCB, Waa maxay sababta maaskarada daboolka u xirto?
1. Maxay BGA ugu jirtaa godka maaskarada alxanka?Waa maxay heerka soo dhawayntu?Re: Ugu horreyntii, daloolka daboolka maaskarada alxanka ayaa ah in la ilaaliyo nolosha adeegga ee via, sababtoo ah daloolka looga baahan yahay booska BGA guud ahaan wuu ka yar yahay, inta u dhaxaysa 0.2 iyo 0.35mm.Sharoobada qaar ma fududa in la qalajiyo ama la uumibixiyo, wayna fududahay in laga tago hadhaaga.Haddi maaskarada alxanka uusan xirin daloolka ama furka...
- Naqshad nus-dalool ah ee Guddiga Wareegga
Godka nuska ah ee la bireeyay waxa uu ka dhigan yahay in dalool qodista ka dib (daloolin, gong jeexdin), ka dibna kan 2aad la qoday oo qaabeeyay, iyo ugu dambeyntii nuska daloolka birta ah (jeexdin) waa la hayaa.Si loo xakameeyo wax soo saarka ee loox-god nus biraha, saarayaasha guddiga wareegyada sida caadiga ah waxay qaadaan tallaabooyin qaar ka mid ah ay sabab u tahay dhibaatooyinka habka ee isgoyska of godad nus biraha ah iyo kuwa aan biraha lahayn.god nus ah oo bir ah...
- Waa maxay sababta inta badan looxyada wareegyada lakabyada badan ay yihiin lakabyo xitaa-lakab ah?
Waxaa jira loox wareeg ah oo hal dhinac ah, laba-dhinac ah iyo lakabyo badan.Tirada looxyada lakabyada badan ma xaddidna.Waxaa hadda jira in ka badan 100-lakab oo PCB ah.PCB-yada lakabka badan ee caadiga ah waa afar lakab iyo lix lakab.Markaa maxay dadku u qabaan su'aasha ah "Waa maxay sababta looxyada badan ee PCB ay u yihiin dhammaan lakabyada xitaa la tiriyey?
- Waa maxay sababta guddiga wareegyada daabacan ay ugu baahan yihiin xakamaynta impedance?
Waa maxay sababta guddiga wareegyada daabacan ay ugu baahan yihiin xakamaynta impedance?Xariiqda calaamadda gudbinta ee aaladda elektiroonigga ah, iska caabbinta ay la kulanto marka signalka-soo noqnoqda sare ama hirarka korantada ee fidinta waxaa loo yaqaan impedance.Waa maxay sababta looxyada PCB ay u noqdaan kuwo aan is adkeyn inta lagu jiro habka wax soo saarka ee warshadda guddiga wareegta?Aynu falanqeyno 4-tan sababood ee soo socda: 1.
