Multi-layer flexible PCB control technology kanye nendlela yokuhlola

U-Capel: Uzakwethu wokukhiqiza we-PCB onezingqimba eziningi omethembayo

Kusukela ngo-2009, uCapel ubehamba phambili embonini yokukhiqiza izinto zikagesi, egxile ekukhiqizeni nasekukhiqizeni amabhodi esifunda aguquguqukayo aphakathi kuya phezulu, amabhodi esekethe aqinile, nama-HDI PCB, futhi usephenduke umkhiqizi othembekile we-electronics. . Inguzakwethu onokwethenjelwa ezinkampanini eziningi ezimbonini ezihlukahlukene. Ngeminyaka engu-15 yezimboni ezicebile kanye nesipiliyoni sezobuchwepheshe, ithimba eliqinile lochwepheshe, kanye nemishini yokukhiqiza ezenzakalelayo ethuthukisiwe ngokugcwele, iCapel izibophezele ekuhlinzekeni amakhasimende ngokukhiqiza okuthembekile nokusheshayo kwe-prototype ukuze baqalise ngempumelelo amaphrojekthi abo.

Kuma-PCB anezingqimba eziningi aguquguqukayo, ubuchwepheshe bokulawula i-impedance nezindlela zokuhlola zidlala indima ebalulekile ekuqinisekiseni ukunemba nokunemba kwenqubo yokukhiqiza.Kulokhu okuthunyelwe kwebhulogi, sizohlola ukuthi ungakhetha kanjani ubuchwepheshe obufanele bokulawula i-impedance kanye nendlela yokuhlola ye-PCB yakho ye-multilayer flexible, nokuthi kungani i-Capel iyinketho ekahle yezidingo zakho zokukhiqiza.

Funda ngobuchwepheshe bokulawula i-impedance

Ubuchwepheshe bokulawula i-impedance bubhekisela ekuphathweni kwe-PCB yangaphakathi kagesi. Iqinisekisa ukuthi amasignali adluliswa ngesekethe ye-PCB awathintwa ukuphazamiseka kwangaphandle, ngaleyo ndlela iqinisekisa ukusebenza okuphelele nokuthembeka kwedivayisi. Kuma-PCB anezendlalelo eziningi aguquguqukayo, ukulawulwa kwe-impedance kuba okubaluleke kakhulu ngenxa yobunkimbinkimbi besekethe.

Isinyathelo sokuqala ekukhetheni ubuchwepheshe obufanele bokulawula i-impedance ukuqonda izidingo ezithile ze-multilayer flexible PCB design. Izinto ezifana nefrikhwensi yesiginali, ukushuba kwebhodi, ukungaguquguquki kwe-dielectric, ukujiya kwethusi, nezinto ezingaphansi kwe-substrate konke kuthinta inani le-impedance. Ngokuthola ngokunembile le mingcele, ungakhetha ubuchwepheshe obufanele bokulawula i-impedance be-PCB yakho.

Izinhlobo ze-Impedans Control Technology

1. Amasu okuklama:Enye indlela yokulawula i-impedance ukuklama isakhiwo se-PCB ukuze kuzuzwe i-impedance oyifunayo. Lokhu kuhlanganisa ukulungisa ububanzi bokulandelela, isikhala, nezibalo zokuthikamezeka ukuze kuhlangatshezwane nezicaciso ezidingekayo. I-Capel isebenzisa abaklami abanolwazi abanolwazi kumasu okulawula i-impedance ukuqinisekisa ukuthi isakhiwo sakho se-PCB enezingqimba eziningi sihlangabezana nezidingo zakho ze-impedance.

2. Ukulawula i-dielectric constant:Ukukhetha into ene-dielectric constant eyaziwa futhi ezinzile kungenye indlela yokufinyelela ukulawulwa kwe-impedance. Ngokukhetha i-substrate enezici ze-dielectric ezinembile, ungagcina amanani angaguquki we-impedance kuyo yonke i-PCB eguquguqukayo ye-multilayer. I-Capel isebenzisa izinto ezisezingeni eliphezulu ezinama-dielectric constants athembekile ukuze kuqinisekiswe ukulawulwa okunembile kwe-impedance.

3. Izingxenye ezishumekiwe:Ukushumeka izingxenye ze-passive, ezifana nama-resistors nama-capacitor, ngaphakathi kwe-PCB kungasiza ekufinyeleleni ukulawulwa kwe-impedance. Lobu buchwepheshe abudingi izingxenye zangaphandle, kunciphisa usayizi nesisindo se-PCB ngenkathi kugcinwa amanani anembile we-impedance. Amandla ka-Capel okushumeka ngokunembile lezi zingxenye athuthukisa kakhulu ukusebenza nokuthembeka kwama-PCB anezingqimba eziningi.

Khetha indlela yokuhlola efanele

Uma ubuchwepheshe obufanele bokulawula i-impedance bukhethiwe, ukuhlolwa okuphelele kubalulekile ukuze kuqinisekiswe ukuthi ama-PCB anezendlalelo eziningi avumelana nezimo ezidingekayo. U-Capel usebenzisa izindlela zokuhlola ezithuthukile ukuze aqinisekise ukunemba nokusebenza kwe-PCB.

1. I-Time Domain Reflectometry (TDR):I-TDR iyindlela evamile yokulinganisa ukungaqhubeki kwe-impedance. Ngokuthumela ukushaya kwe-pulse ngomugqa wokudlulisela nokuhlaziya i-waveform ebonisiwe, ukungafani kwe-impedance nezinye izinkinga zobuqotho besignali zingabonakala. I-Capel isebenzisa ukuhlola kwe-TDR ukukala ngokunembile ukuthintana kwama-PCB anezingqimba eziningi aguquguqukayo.

2. I-Vector Network Analyzer (VNA):I-VNA iyithuluzi elinemisebenzi eminingi elisetshenziselwa ukukala izici zikagesi zemishini yamafrikhwensi aphezulu, okuhlanganisa nokuvinjelwa. Ihlinzeka ngezilinganiso ezinembile ngebanga elibanzi lefrikhwensi, iyenze ifaneleke ukuhlola ama-PCB anezingqimba eziningi aguquguqukayo anezidingo ezahlukahlukene ze-impedance. U-Capel usebenzisa ukuhlolwa kwe-VNA ukuze aqinisekise ubuqotho bemiklamo ye-PCB.

3. Isiqephu sokuhlola:Ukusebenzisa ipheshi yokuhlola kuyingxenye emele i-PCB yangempela futhi kuyindlela esebenzayo yokuqinisekisa inani lokuvimba. Ngokwenza ingxenye ethile ye-PCB enenani elaziwayo lokuvimba, abakhiqizi bangaqhathanisa ukuvinjelwa okukaliwe nevelu elilindelekile. U-Capel usebenzisa amakhuphoni okuhlola ukuze aqinisekise ukunemba kokulawulwa kwe-impedance kuma-PCB avumelana nezingqimba eziningi.

Kungani ukhetha i-Capel ngezidingo zakho ze-PCB ezinezingqimba eziningi?

Ngolwazi olubanzi ekukhiqizeni amabhodi esifunda aguquguqukayo ekhwalithi ephezulu kanye nokuzibophezela ekusebenziseni ubuchwepheshe obuthuthukisiwe, i-Capel iyinketho ekahle yezidingo zakho ze-PCB ezinezingqimba eziningi. Khetha i-Capel, uzozuza kulokhu:

1. Imboni ecebile nolwazi lobuchwepheshe:
Isipiliyoni seminyaka engu-15 sikaCapel embonini siwubufakazi bokuzibophezela kwakhe kukhwalithi nokusungula izinto ezintsha. I-Capel ineqembu eliqinile lochwepheshe abaqonda izinselele eziyingqayizivele ezihlobene nokukhiqizwa kwe-PCB eguquguqukayo enezingqimba eziningi futhi inganikeza ukuqonda okubalulekile nezisombululo.

2. Imishini yokukhiqiza ezenzakalelayo ethuthukisiwe:
Ukutshalwa kwezimali kukaCapel kumishini yokukhiqiza ezenzakalelayo ethuthukisiwe kuqinisekisa ukunemba nokusebenza kahle kuyo yonke inqubo yokukhiqiza. Ngokusebenzisa ubuchwepheshe bamuva nje, i-Capel inikeza i-prototyping ethembekile, esheshayo ukuze ukwazi ukuqedela iphrojekthi yakho ngesikhathi.

3. Ukuzibophezela empumelelweni yekhasimende:
E-Capel, ukwaneliseka kwamakhasimende kubaluleke kakhulu. Ngokuhlinzeka ngokukhiqiza okuthembekile kwe-prototype, ubuchwepheshe bezobuchwepheshe kanye nenkonzo yamakhasimende eyingqayizivele, u-Capel uzibophezele ekusizeni amakhasimende ethule ngempumelelo amaphrojekthi awo. Ukugxila kukaCapel empumelelweni yekhasimende kuyenza ihluke kwabanye abakhiqizi be-PCB.

Ngokufigqiwe,ukukhetha ubuchwepheshe obufanele bokulawula i-impedance nezindlela zokuhlola zama-PCB aguquguqukayo ahlukahlukene kubalulekile ukuze uthole imiphumela enembile nethembekile. Ngokubambisana ne-Capel, ungakwazi ukusebenzisa isipiliyoni sayo esibanzi semboni, okokusebenza okuthuthukisiwe kokukhiqiza nokuzibophezela empumelelweni yamakhasimende ukuze uqinisekise ukuthi i-PCB yakho enezingqimba eziningi eguquguqukayo ihlangabezana nekhwalithi ephezulu kanye nezindinganiso zokusebenza.
