Dizayina izinselelo lapho usebenza ne-HDI rigid flex PCB

Kulokhu okuthunyelwe kwebhulogi, sizohlola izinselelo ezijwayelekile zokuklama onjiniyela ababhekana nazo lapho besebenza nama-HDI aqinile-flex PCB futhi sixoxe ngezixazululo ezingaba khona zokunqoba lezi zinselele.

Ukusebenzisa i-high-density interconnect (HDI) i-rigid-flex PCBs kungaletha izinselele ezithile zedizayini ezingaba nomthelela ekusebenzeni okuphelele nokuthembeka kwedivayisi ye-elekthronikhi. Lezi zinselele zivela ngenxa yobunkimbinkimbi bezinhlanganisela zezinto ze-PCB eziqinile neziguquguqukayo, kanye nokuminyana okuphezulu kwezingxenye nezixhumi.

1. I-Miniaturization kanye nesakhiwo sengxenye

Enye yezinselelo ezinkulu zedizayini ye-HDI rigid-flex PCBs ukuzuza ukwenziwa kancane kuyilapho uqinisekisa ukubekwa kwengxenye okulungile. I-Miniaturization iyindlela evamile emishinini kagesi, abakhiqizi abalwela ukwenza izinto zikagesi zibe zincane futhi zihlangane kakhudlwana. Nokho, lokhu kubangela izinselele ezinkulu ekubekeni izingxenye ku-PCB nokugcina imvume edingekayo.

isisombululo:
Ukuze banqobe le nselele, abaklami badinga ukuhlela ngokucophelela ukubekwa kwengxenye futhi balungise izindlela zomzila. Sebenzisa amathuluzi e-CAD athuthukisiwe ukuze usize ngokunembile ukubeka izingxenye futhi uqinisekise ukuthi izidingo zokugunyazwa ziyahlangatshezwa. Ukwengeza, ukusebenzisa izingxenye ezincane, eziminyene kungasiza ekwenzeni i-miniaturization ngaphandle kokuphazamisa ukusebenza okuphelele.

2. Ubuqotho besignali kanye ne-crosstalk

I-HDI rigid-flex PCBs ivamise ukuba nezendlalelo eziningi, okwenza kube semqoka ukubhekana nezindaba zobuqotho zesignali ezifana ne-crosstalk, ukungafani kokuphazamiseka, nomsindo. Lezi zinkinga zingabangela ukuncishiswa kwesignali noma ukuphazamiseka, okungathinta kakhulu ukusebenza okuphelele kwedivayisi.

isisombululo:
Abaklami banganciphisa izinkinga zesignali yobuqotho ngokusebenzisa amasu anjengomzila olawulwayo we-impedance, ukusayina okuhlukile, nesakhiwo esifanele sendiza yaphansi. Isofthiwe yokulingisa ubuqotho besignali ingase isetshenziselwe ukuhlaziya nokuthuthukisa izindlela zesignali ukuze kukhonjwe noma yiziphi izinkinga ezingaba khona ngaphambi kokukhiqiza. Ngokucabangela ngokucophelela umzila wesignali nokusebenzisa amasu okuvikela e-EMI afanelekile, abaklami bangaqinisekisa ubuqotho besignali futhi banciphise i-crosstalk.

3. Ukuguquka kusuka ekuguquguqukeni kuya ekuqineni

Ushintsho phakathi kwezingxenye eziguquguqukayo neziqinile ze-PCB lungadala izinselele zokuthembeka kwemishini nokuxhumeka kukagesi. Indawo eguquguqukayo iye kweziqinile idinga idizayini ecophelelayo ukuze kuvinjelwe noma yikuphi ukugxila kwengcindezi noma ukwehluleka komshini.

isisombululo:
Ukuhlela ngendlela efanele indawo eguquguqukayo-kuya-qinile kubalulekile ukuze kuqinisekiswe ukuxhunywa kukagesi okuthembekile nokuzinzile. Abaklami kufanele bavumele izinguquko ezibushelelezi nezihamba kancane ekwakhiweni komklamo futhi bagweme ama-engeli abukhali noma ukushintsha okungazelelwe kokuqondisa. Ukusebenzisa izinto zokuxhuma eziguquguqukayo kanye nama-stiffener nakho kusiza ukunciphisa ukugxila kwengcindezi futhi kuthuthukisa ukwethembeka kwemishini.

4. Ukuphathwa kokushisa

Ukuphatha ukukhishwa kokushisa kuyisici esibalulekile se-HDI rigid-flex PCB design. Imvelo ehlangene yalawa ma-PCB iphumela ekukhuleni kokushisa, okuthinta ukusebenza nokuphila isikhathi eside kwezingxenye ze-elekthronikhi.

isisombululo:

Amasu okuphatha okushisayo, njengokusetshenziswa kwamasinki okushisa, ama-thermal vents, nokubekwa kwengxenye ngokucophelela, angasiza ekuhlakazeni ukushisa kahle. Ukwengeza, abaklami kufanele bacabangele ukusebenzisa ukugeleza komoya okufanelekile kanye nezindlela zokupholisa kuyo yonke imiklamo yedivayisi ukuze baqinisekise ukunqanyulwa kokushisa okwanele.

5. Ukukhiqiza kanye Nokuhlanganisa

Inqubo yokukhiqiza kanye nokuhlanganisa yama-PCB e-HDI aqinile-flex ingaba yinkimbinkimbi kunama-PCB endabuko. Imiklamo eyinkimbinkimbi nezendlalelo eziningi ziletha izinselele zokuhlanganisa, futhi noma yimaphi amaphutha enqubweni yokukhiqiza angaholela ekushiyekeni noma ekuhlulekeni.

isisombululo:
Ukusebenzisana phakathi kwabaklami nabakhiqizi kubalulekile ukuze kuqinisekiswe inqubo yokukhiqiza eshelelayo. Abaklami kufanele basebenzisane eduze nochwepheshe bokukhiqiza ukuze bathuthukise idizayini yokwenziwa, kucatshangelwa izici ezifana nokufakwa kwamaphaneli, ukutholakala kwengxenye, namandla okuhlanganisa. I-Prototyping nokuhlola okuphelele ngaphambi kokukhiqizwa kochungechunge kungasiza ekuhlonzeni noma yiziphi izinkinga futhi kuthuthukise idizayini yokusebenza kahle nekhwalithi.

Ngokufigqiwe

Ukusebenzisa i-HDI rigid-flex PCBs kuveza izinselelo zedizayini eziyingqayizivele okudingeka zibhekwe ngokucophelela ukuze kuqinisekiswe izinto zikagesi ezithembekile nezisebenza kakhulu. Ngokucabangela izici ezifana ne-miniaturization, ubuqotho besignali, ukuguquguquka okuguquguqukayo kuya kokuqinile, ukuphathwa kwe-thermal, kanye nokwenziwa, abaklami banganqoba lezi zinselele futhi balethe imikhiqizo ephumelelayo neqinile.
