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.
Saddexaad, qiimayaashu way kala duwan yihiin sababtoo ah kakanaanta iyo cufnaanta.
PCB waxay noqon doontaa kharash kala duwan xitaa haddii agabka iyo habsocodka ay isku mid yihiin, laakiin leh kakanaanta iyo cufnaanta kala duwan.Tusaale ahaan, haddii ay jiraan 1000 godad oo ku yaal labada loox ee wareegga, dhexroorka daloolka mid ka mid ah wuxuu ka weyn yahay 0.6mm iyo dhexroorka daloolka guddiga kale wuxuu ka yar yahay 0.6mm, taas oo samayn doonta kharashyo kala duwan oo qodista.Haddii laba loox oo wareeg ah ay isku mid yihiin codsiyada kale, laakiin ballaciisu waa ka duwan yahay sidoo kale wuxuu keenaa kharashyo kala duwan, sida hal ballaciisu waa ka weyn yahay 0.2mm, halka kan kale ee leh uu ka yar yahay 0.2mm.Sababtoo ah ballaca looxyada wax ka yar 0.2mm ayaa leh heerka cilladaysan, taas oo macnaheedu yahay qiimaha wax soo saarku wuu ka sarreeyaa midka caadiga ah.
Afar, qiimayaashu way kala duwan yihiin sababtoo ah shuruudaha macaamiisha kala duwan.
Shuruudaha macaamiisha ayaa si toos ah u saameyn doona heerka aan cillad lahayn ee wax soo saarka.Sida hal guddi oo waafaqsan IPC-A-600E class1 waxay u baahan tahay 98% heerka gudbinta, halka heshisyada fasalka 3 ay u baahan yihiin oo kaliya inay haystaan 90% heerka baasas, taasoo keenta kharashyo kala duwan warshadda oo ugu dambeyntii horseedaysa isbeddel ku yimaada qiimaha alaabta.
