Kuyini ukunqwabelana?
Ukupakisha kusho ukuhlelwa kwezendlalelo zethusi nezendlalelo ezivikelayo ezakha i-PCB ngaphambi komklamo wesakhiwo sebhodi.Ngenkathi isitaki sesendlalelo sikuvumela ukuthi uthole ukujikeleza okwengeziwe ebhodini elilodwa ngokusebenzisa izendlalelo zamabhodi e-PCB ahlukahlukene, ukwakheka kwe-PCB stackup design kunikeza ezinye izinzuzo eziningi:
• Isitaki sesendlalelo se-PCB singakusiza ukuthi unciphise ukuba sengozini kwesekethe yakho emsindweni wangaphandle futhi sinciphise imisebe futhi sinciphise ukukhathazeka nokushayisana kwezakhiwo ze-PCB enesivinini esikhulu.
• Isitaki se-PCB esendlalelo esihle singakusiza futhi ukuthi ulinganisele izidingo zakho zezindlela zokukhiqiza ezingabizi kakhulu, eziphumelelayo nokukhathazeka mayelana nezinkinga zobuqotho besignali.
• Isitaki sesendlalelo se-PCB esilungile singathuthukisa Ukuhambisana Kwe-Electromagnetic komklamo wakho futhi.
Ngokuvamile kuzoba yinzuzo kuwe ukulandela ukucushwa kwe-PCB estakiwe kwezinhlelo zakho zokusebenza ezisekelwe ebhodini lesekethe.
Kuma-PCB anezingqimba eziningi, izendlalelo ezijwayelekile zifaka indiza yaphansi (indiza ye-GND), indiza yamandla (indiza ye-PWR), nezendlalelo zesignali zangaphakathi.Nali isampula le-PCB enezingqimba ezingu-8.
I-ANKE PCB ihlinzeka ngamabhodi esekethe ezendlalelo eziningi/ezingqimba eziphakeme ebangeni elisuka ku-4 kuya kwezingu-32, ukujiya kwebhodi kusuka ku-0.2mm kuya ku-6.0mm, ukujiya kwethusi kusuka ku-18μm kuya ku-210μm (0.5oz kuya ku-6oz), ugqinsi lwethusi olungaphakathi olusuka ku-18μm kuya ku-70μm (0.5) oz ukuya ku-2oz), kanye nesikhala esincane phakathi kwezendlalelo ukuya ku-3mil.
