Kulo nyaka, okuhlaselwe ubhubhane olusha lomqhele, ukuhlinzekwa kwezinto zokusetshenziswa kwe-PCB akwanele, futhi amanani ezinto zokusetshenziswa nawo ayakhuphuka.Izimboni ezihlobene ne-PCB nazo ziye zathinteka kakhulu.Ngenqubekelaphambili evamile yephrojekthi, onjiniyela kufanele bacabangele ukuthuthukisa imiklamo ukuze behlise izindleko ze-PCB.Khona-ke, yiziphi izici ezizothinta izindleko zokukhiqiza ze-PCB?
Izici eziyinhloko zithinta izindleko ze-PCB yakho
1. Usayizi we-PCB kanye nenani
Kulula ukuqonda ukuthi usayizi nobuningi buzothinta kanjani izindleko ze-PCB, usayizi kanye nenani kuzosebenzisa izinto eziningi.
2. Izinhlobo zezinto ezisetshenziswayo ze-substrate
Ezinye izinto ezikhethekile ezisetshenziswa endaweni ethile yokusebenza zingabiza kakhulu kunezisetshenziswa ezivamile.Ukwenza Amabhodi Esifunda Aphrintiwe kuncike ezicini eziningana ezisekelwe kuhlelo lokusebenza, ezibuswa ikakhulukazi yi-frequency kanye nesivinini sokusebenza, kanye nezinga lokushisa eliphezulu lokusebenza.
3. Inani lezendlalelo
izendlalelo eziningi zihumushela ezindlekweni ezengeziwe ngenxa yezinyathelo zokukhiqiza ezengeziwe, impahla eyengeziwe, nesikhathi sokukhiqiza esengeziwe.
4. PCB inkimbinkimbi
Ubunkimbinkimbi be-PCB buncike enanini lezendlalelo kanye nenani le-vias kusendlalelo ngasinye, njengoba lokhu kuchaza ukuhlukahluka kwezingqimba lapho i-vias iqala futhi ime khona, edinga izinyathelo eziningi zokulalisa kanye nokubhola kwinqubo yokukhiqiza ye-PCB.Abakhiqizi bachaza inqubo yokucwala njengokucindezela izendlalelo ezimbili zethusi kanye nama-dielectrics phakathi kwezingqimba zethusi eziseduze kusetshenziswa ukushisa nokucindezela ukwakha i-laminate ye-PCB enezingqimba eziningi.
Indlela yokuthuthukisa umklamo wakho?
1. Ithrekhi negebe geometry- thinner kubiza kakhulu.
2. Ukulawulwa kwe-impedance- izinyathelo zenqubo eyengeziwe zandisa izindleko.
3. Usayizi nokubalwa kwezimbobo- izimbobo eziningi nama-diameter amancane kubiza ukuya phezulu.
4. Ama-vias axhunyiwe noma agcwaliswe nokuthi ambozwe ngethusi- izinyathelo zenqubo eyengeziwe zikhuphula izindleko.
5. Ugqinsi lwethusi ezingqimbeni- ukujiya okuphezulu kusho izindleko eziphezulu.
6. Ukuphela kwendawo, ukusetshenziswa kwegolide nokujiya kwalo- Impahla eyengeziwe nezinyathelo zenqubo kwandisa izindleko.
7. Ukubekezelelana- ukubekezelelana okuqinile kuyabiza.
Ezinye izici zithinta izindleko zakho.
Lezi zici zezindleko ezincane ezibandakanya isigaba III zincike kukho kokubili, umenzi kanye nokusetshenziswa kwe-PCB.Ngokuyinhloko zibandakanya:
1. PCB ukujiya
2. Ukwelashwa okuhlukahlukene kwendawo
3. I-solder masking
4. Ukuphrinta kwenganekwane
5. Isigaba sokusebenza se-PCB (IPC Class II/ III njll.)
6. PCB contour- ngokukhethekileyo z- axis umzila
7. Ukufakwa eceleni noma onqenqemeni
I-PHILIFAST izokunikeza iziphakamiso ezingcono kakhulu ngokufanele ukukusiza wehlise izindleko zamabhodi e-PCB.
