4 lakab pcb leh far dahab ah oo ku jira nidaamka maqalka dhijitaalka ah

Qalabka Alaabta

Sida alaab-qeybiyaha teknoolajiyada kala duwan ee PCB, mugga, fursadaha wakhtiga hogaanka, waxaanu leenahay xulashada agabka caadiga ah kaas oo baaxad weyn oo noocyada kala duwan ee PCB ah lagu dabooli karo oo had iyo jeer laga helo guriga.

Shuruudaha agabka kale ama khaaska ah sidoo kale waa la buuxin karaa xaaladaha badankood, laakiin, iyadoo ku xiran shuruudaha saxda ah, ilaa 10 maalmood oo shaqo ayaa loo baahan karaa si loo soo iibiyo alaabta.

Nala soo xidhiidh oo kala hadal baahiyahaaga mid ka mid ah iibkayaga ama kooxda CAM.

Agabka caadiga ah ee kaydka lagu hayo:

Dhumucda lakabyada gudaha: Heerka - 18µm iyo 35 µm,

marka la codsado 70 µm, 105µm iyo 140µm

Nooca walxaha: FR4

Tg: qiyaastii.150°C, 170°C, 180°C

εr at 1 MHz: ≤5,4 (caadi: 4,7) Wax badan ayaa la heli karaa haddii la codsado

Isku-duubni

4-da lakab ee daabacan ee wareegyada wareegyada ayaa leh 3 ka mid ah lakabyada kaliya iyo lakabka dhulka oo ka dhigaya 4 lakab guud ahaan.

Dhammaan lakabyadan waxaa loo isticmaalaa hab-socodka calaamadaha.

Labada berkedood ee ugu horreeya waxay dhex yaalliin xudunta dhexdeeda waxaana inta badan loo adeegsadaa sida muraayadaha korantada ama waxaa badanaa loo tixraacaa jihaynta calaamadaha.

Si fudud u hadalka 4-lakabka PCB-ga ayaa leh 2 ka mid ah VCC-ga singlea iyo lakabka dhulka.

Qodobbada muhiimka ah ee iibsashada pcb

Inta badan iibsadayaasha warshada elektiroonigga ah ayaa ku wareeray qiimaha PCB-yada.xitaa dadka qaar oo sannado badan khibrad u leh soo iibinta PCB waxaa laga yaabaa inaysan si buuxda u fahmin sababta asalka ah.Dhab ahaantii, qiimaha PCB wuxuu ka kooban yahay arrimaha soo socda:

Marka hore, qiimayaashu way kala duwan yihiin iyadoo ay ugu wacan tahay agabyada kala duwan ee lagu isticmaalo PCB-ga.

Qaadashada lakabyada caadiga ah ee pcb ee caadiga ah, laminate-ku wuu kala duwan yahay FR-4, CEM-3, iwm. leh dhumucdiisuna waxay u dhaxaysaa 0.2mm ilaa 3.6mm.Dhumucdiisuna waxay ku kala duwan tahay 0.5Oz ilaa 6Oz, kuwaas oo dhammaantood sababay farqi qiimo weyn leh.Qiimaha khadka alxanka sidoo kale wuu ka duwan yahay qalabka heerkulbeegga caadiga ah iyo walxaha khad cagaaran oo sawir leh.

Marka labaad, qiimayaashu way kala duwan yihiin sababtoo ah hababka wax soo saarka ee kala duwan.

Nidaamyada wax-soo-saarka ee kala duwan waxay keenaan kharashyo kala duwan.Sida looxa dahabka ah ee dahabka ah iyo guddiga daasadaha, qaabka wareegga iyo feerka, isticmaalka xadhkaha shaashadda xariirta ah iyo khadadka filimka qalalan waxay sameyn doonaan kharashyo kala duwan, taasoo keentay kala duwanaansho qiimo leh.
