Ukucatshangelwa Kwezindleko

Izinto eziningana zithinta izindleko zama-PCB aphuzi, okuhlanganisa nokukhetha kombala, lapho okuphuzi kuvame ukubiza ngaphezu kuka-5-10% kunoluhlaza kuye ngobuningi. Inani le-oda linganciphisa kakhulu izindleko, kanti izindleko zesilinganiso zinikeza isaphulelo esingafika ku-20% ngokunyuka okungu-10×. Ezinye izinto ezifana nobunzima bebhodi, ukwakhiwa okuguquguqukayo vs. okuqinile, ukukhetha kokuqeda ubuso , kanye nezikhathi zokuhola nazo zithinta amanani, ngamaphrimiyamu asukela ku-0-150% ngokusekelwe ezintweni, ukuqeda, kanye nokuphuthuma. Isibonelo, amabhodi aguquguqukayo abiza kakhulu ngenxa yokwehluka kwezinto kanye nezinqubo, kanti ukuqeda ubuso njenge-ENIG noma igolide kuza nezinzuzo zokusebenza ezengeziwe.

Amasu okuthuthukisa izindleko ahlanganisa ukulungiswa kwedizayini, njengokulinganisa ukujiya kwebhodi kuya ku-1.6mm kanye nokunciphisa isibalo sesendlalelo. Ukuhlanganisa imiklamo eminingi nge-oda elilodwa kungehlisa izintengo, njengoba kungase kube nokuhlela ama-oda onyaka ukuze uthole amanani angcono. Ukulinganisa ukucaciswa ngokukhawulela ukubekezelelana nokusebenzisa izinto ezijwayelekile kunciphisa izindleko ezingadingekile, kuyilapho ukuphatha izikhathi zokuhola kusiza ukugwema izindleko zokuxhamazela. Ingqikithi yezindleko zobunikazi (i-TCO) ibonisa i-ROI esuka kuma-PCB aphuzi ngokulawula ikhwalithi esheshayo, amaphutha ambalwa, namazinga aphansi okusebenza kabusha. Ama-PCB aphuzi anganikeza inani elibalulekile, i-ROI ibonakale ngokushesha ngamaqoqo amakhulu futhi inikeze iprimiyamu yenani lomkhiqizo nokwaneliseka kwamakhasimende.
