Izindleko zokukhiqiza zebhodi lesifunda kube yinto ekhathaza kakhulu kubo bonke onjiniyela be-elekthronikhi, bafuna ukuthola inzuzo enkulu yemikhiqizo yabo ngezindleko eziphansi kakhulu. Nokho, yini ngempela ethinta izindleko zokukhiqiza zebhodi lesifunda? Lapha, uzo yazi zonke izici ezingase zengeze izindleko ze-PCB yakho.
Isizathu esiyisisekelo esenza izindleko ze-PCB
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 ezintweni ezimbalwa ezisuselwe kuhlelo lokusebenza, ezibuswa ikakhulukazi ukuvama 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 ye-lamination njengokucindezela izendlalelo ezimbili zethusi kanye nama-dielectrics phakathi kwezingqimba zethusi eziseduze kusetshenziswa ukushisa nokucindezela ukwenza i-laminate ye-PCB eminingi.
Izici zentengo ezivela ezidingweni zokukhiqiza pf PCB uqobo
1. I-track and gap geometry—i-thinner ibiza kakhulu.
2. Ukulawulwa kwe-impedance-izinyathelo zenqubo ezengeziwe 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 ezengeziwe zenyusa izindleko.
5. Ugqinsi lwethusi ezingqimbeni—ukuqina okuphezulu kusho izindleko eziphakeme.
6. Ukuphela kwendawo, ukusetshenziswa kwegolide nokujiya kwalo—Impahla eyengeziwe nezinyathelo zenqubo kwandisa izindleko.
7. Ukubekezelelana—ukubekezelelana okuqinile kuyabiza.
Ezinye izici ezithonya izindleko ze-PCB
Lezi zici zezindleko ezincane ezibandakanya isigaba III zincike kukho kokubili, umenzi kanye nokusetshenziswa kwe-PCB.Ngokuyinhloko zibandakanya:
1. NPCB ukujiya.
2.Ukwelashwa okuhlukahlukene kwendawo.
3. ukufihla ubuso abadala.
4. Ukuphrinta kwenganekwane.
5. Isigaba sokusebenza se-PCB (IPC Class II/III njll.).
6. PCB contour—ikakhulukazi kumzila we-z-axis.
7. Ukufakwa eceleni noma onqenqemeni.
I-PCBA izokunikeza iziphakamiso ezingcono kakhulu ngokufanele ukukusiza wehlise izindleko zamabhodi e-PCB,
