Si loo hagaajiyo waxtarka wax-soo-saarka loona dhimo qiimaha wax-soo-saarka gudahaPCB shirkahabka, loox wareegga qaawan sida caadiga ah ka dhigi in panel wax soo saarka, kaas oo fududayn kara warshad processing PCBA si ay u fuliyaan alxanka chip.Kuwa soo socdaa waxay ka hadli doonaan hababka la wadaagay ee caadiga ah iyo mabaadiida guddiga wareegga.
Mabda'a guddida PCB:
1. Baaxadda guddiga PCB ballaca guddiga ≤ 300mm (line Fuji);Haddii aad u baahan tahay qaybinta tooska ah, cabbirka PCB waa inuu ahaadaa ≤ 125mm(W) × 180mm(L).
2. Qaabka PCB waa inuu u dhawaadaa afargeeska ilaa inta suurtogalka ah, waxaana lagu talinayaa in looxa kabiddu uu yahay (2*2,3 *3,4* 4) guddi kasta.
3. Qaabka dibadda ah (cidhifka isku dhufashada) ee looxa wareeggu waa inuu qaataa nakhshad xidhan si loo hubiyo in guddida PCB-ga aanu qudhmi doonin ka dib marka lagu hagaajiyo qalabka.
4. Masaafada xarunta guddiga PCB yar waa in lagu xakameeyaa 75mm ~ 145mm.
5. Ma jiro qalab waaweyn ama qalab soo baxaya oo u dhow meesha isku xirka ee u dhaxaysa jir ka baxsan ee looxa kabidda iyo looxa yar gudaha, waana in ay jiraan meel bannaan oo ka weyn 0.5mm inta u dhaxaysa qaybaha iyo cidhifka guddiga PCB hubi shaqada caadiga ah ee qalabka goynta.
6. Afarta geesood ee fareemka dibadda ee PCB, afar godad ayaa la furay, dhexroorka daloolkuna waa (4mm ± 0.01mm);Xoogga daloolku waa inuu ahaadaa mid dhexdhexaad ah si loo hubiyo inuusan jabin inta lagu jiro habka rarida iyo dejinta;Dhexroorka daloolka iyo saxnaanta booska waa inay ahaataa mid sare, daloolkuna waa inuu ahaadaa mid siman.
7. Loox kasta oo yar oo PCB ah waa inuu lahaadaa ugu yaraan saddex godad, 3 ≤ dhexroorka daloolka ≤ 6mm, fiilooyinka ama SMT lagama oggola gudaha 1mm dalool meelaynta.
8. Markaad dejinayso barta meelaynta tixraaca, aag alxanka oo aan iska caabin ahayn oo 1.5mm ka weyn barta meelaynta ayaa inta badan lagu hayaa agagaarka barta meelaynta.
9. Qaybaha waaweyn waa in lagu bixiyaa meelaynta ama godadka meelaynta, sida: makarafoon, interface batari, microswitch, headset interface, motor, iwm.
Siyaabaha PCB-ga caadiga ah ee isku xidhan ee guddida:
1, V-CUT
V-CUT waxay ka dhigan tahay in dhowr loox ama isla loox la isku dari karo oo la isku dari karo, ka dibna V-groove waxaa lagu gooyn karaa mashiinka V-CUT inta u dhaxaysa looxyada ka dib marka PCB-ga la isticmaalo, taas oo jabin karta marka la isticmaalayo.Waa hab aad loo jecel yahay maalmahan.
2. Godad feeray
Feedhku waxa loola jeedaa wax-shiidid maran inta u dhaxaysa taarikada ama taarikada gudaha iyadoo wata mishiinka wax-shiidka sida loo baahdo, kaas oo u dhigma qodista.
3. godka shaambada
Tani waxay ka dhigan tahay isticmaal dalool yar si aad ugu xidho guddiga PCB, kaas oo u eg qaabka sawtooth ee shaambada, sidaas darteed waxaa loo yaqaannaa isku xirka godka shaambada.Xidhiidhka daloolka shaambada wuxuu u baahan yahay koontarool sare oo ku wareegsan guddiga, taas oo ah kaliya god yar oo shaabad ah ayaa loo isticmaali karaa in lagu beddelo khadka V.
