Amabhodi Esekethe Aphrintiwe Ama-multilayer
IYINI I-PCB YABANINGI?
Kuyi-PCB eyenziwe ngezingqimba zethusi eziqhutshwayo ezintathu noma ngaphezulu. I-foil conductive ibonakala iyizendlalelo ezihlukahlukene zebhodi lesifunda elinamacala amaningi. Izendlalelo ezihlukene zangaphakathi zicutshungulwa ngazimbili (kumongo) bese zihlanganiswa kusetshenziswa i-prepreg njengongqimba oluvikelayo. Izendlalelo zibe sezibekwa ngendlela yokuthi zombili izinhlangothi ze-PCB zingasetshenziswa ukukhweza izingxenye ezinokulandelela okwengeziwe/ukuxhumana kukagesi ngaphakathi ebhodini. Ama-Vias asetshenziswa njengomthombo wokuxhumana kukagesi phakathi kwezendlalelo ezihlukene ze-PCB enezingqimba eziningi.
Imikhiqizo eminingi isebenzisa ama-PCB anezingqimba eziningi, okuhlanganisa amakhompyutha, okokusebenza kwezokwelapha, amasistimu asemotweni, i-GPS nezinhlelo zesathelayithi, amasistimu okulawula izimboni.
Sicela usithinte uma udinga ulwazi olwengeziwe noma usizo, siyajabula ukukusiza.
Imininingwane Yomkhiqizo
| Isici | Imininingwane yezobuchwepheshe ye-AREX |
|---|---|
| Inombolo yezendlalelo | Izingqimba ezi-4 - 22 ezijwayelekile, izendlalelo ezingama-30 zithuthukile, i-prototype yezendlalelo ezingama-40. |
| Amaphuzu avelele ezobuchwepheshe | Izendlalelo eziningi ze-epoxy glass fiber ezihlanganiswe ndawonye nezingqimba eziningi zethusi ezinobukhulu obuhlukahlukene. |
| Izinto zokwakha | Ukusebenza okuphezulu kwe-FR4, i-FR4 ye-halogen-free, ukulahlekelwa okuphansi nezinto ezisetshenziswayo eziphansi zika-D |
| Izisindo zethusi (ziqediwe) | 18μm – 210μm, eziphambili 1050μm / 30oz |
| Ithrekhi negebe elincane | 0.075mm / 0.075mm |
| Ubukhulu be-PCB | 0.40mm – 7.0mm |
| Ubukhulu obukhulu bobukhulu | 580mm x 1080mm, ethuthukisiwe 610mm x 1400mm |
| Ukuqedwa kobuso kuyatholakala | I-HASL (SnPb), i-LF HASL (SnNiCu), i-OSP, i-ENIG, i-Immersion Tin, i-Immersion Silver, igolide le-Electrolytic, iminwe yegolide |
| Ubuncane bokuprakthiza komshini | 0.20mm |
| Ubuncane be-laser drill | 0.10mm ejwayelekile, 0.075mm ethuthukisiwe |
Isevisi yomkhiqizo
Akukho okuthinta izindleko nekhwalithi ye-PCB njengomklamo wokuqala. Njengoba imikhiqizo yesimanje ye-elekthronikhi kulindeleke ukuthi inikeze imisebenzi ethuthuke kakhulu, kuyilapho imikhiqizo ngokwayo iba mincane futhi iba mincane, lokhu kubeka izidingo ezinkulu ekwakhiweni kwe-PCB kanye nokubaluleka kokwenza izinqumo ezifanele esigabeni sokuklama.
Ngaphezu kuka-30% wamaphakethe wedatha we-Gerber esiwatholayo anezinkinga ezithile, ngokuvamile, ulwazi olungacacile, amaphutha, ukungqubuzana kwemithetho yokuklama, ulwazi olungekho kanye nokungqubuzana phakathi kwedatha kanye nokucaciswa. Ukuvimbela ukuthi kube okungalungile kusukela ekuqaleni, sihlanganise le mihlahlandlela yokuklama, ukuze siyisebenzise njengohlu lokuhlola.
Uma usebenzisa inhlanganisela yamapharamitha, kufanele uhlale uxhumane nathi ukuze uthole isisombululo.
