I-HDI PCB kumadivayisi ezokwelapha: Inika amandla Ukunemba kanye Nokwenza Okuncane

Isingeniso - Kungani I-Medical HDI PCB Technology Ibalulekile

Imboni ye-elekthronikhi yezokwelapha idinga amadivayisi amancane, ahlakaniphile, futhi athembekile athuthukisa imiphumela yeziguli ngenkathi enciphisa ukuhlasela. Lokhu kuthuthuka kudinga amabhodi wesekethe akwazi ukusekela ukuminyana kwezingxenye eziphezulu, agcine ubuqotho besiginali ezindaweni ezihlangene, futhi alethe ukuthembeka okungantengantengi esikhathini eside sokusebenza. Ubuchwepheshe be-Medical HDI PCB bubhekana nalezi zidingo ngokusebenzisa ukuxhumana okuminyana kakhulu, izindlela zokulawula ukuvimba ezilawulwa ngokunembile, kanye nokusebenza kahle kwendawo okwenziwe ngcono.

Ukuhlanganiswa kwe-PCB encane yemishini yezokwelapha sekubalulekile. Njengoba okokusebenza kokuxilonga kuba nokuphatheka, amamonitha agqokekayo ancipha abe yizici zefomu elilingana nesichibi, futhi izinto ezifakelwayo zidinga izindlu ezihambelana ne-biocompatible, ukwakheka kwesekethe engaphansi kufanele kusekele ukusebenza okuyinkimbinkimbi ngokwandayo ngaphakathi kwezimvilophu ezibonakalayo ezinciphayo.

Izidingo Zokuklama Eziyinhloko ze-Medical HDI PCB

Izinhlelo zokusebenza ze-elekthronikhi zezokwelapha zibeka izithiyo ezihlukile ezizihlukanisa nezidingo zebhodi lesekethe yabathengi noma yezimboni. Ama-PCB e-HDI yezokwelapha kufanele abonise ukusebenza okungenasici kuyo yonke iminyaka yokusebenza okuqhubekayo, ngokuvamile ezindaweni zomzimba eziyinselele lapho ukuguquka kwezinga lokushisa, ukuchayeka komswakamo, kanye nokucindezeleka komshini kwenzeka njalo.

Amapharamitha Okusebenza Okubalulekile

Onjiniyela abasebenza nge-PCB encane yemishini yezokwelapha babhekana nezinselele ezihlukile:

• Ukuthembeka okuphezulu nokuzinza kwesikhathi eside - Izimo zezokwelapha zidinga ukusebenza okungaphumeleli nhlobo ngempilo yokusebenza elinganiswa ngeminyaka noma amashumi eminyaka.
• Idizayini ehlangene nokwakhiwa okungasindi - Ibalulekile kuma-biosensors agqokekayo kanye namadivayisi okwelapha afakelwayo avinjelwa ukulinganiselwa kwe-anatomical.
• Ubuqotho besignali nokusebenza komsindo ophansi - Imishini yezokwelapha ivamise ukulinganisa amasignali ebhayoloji ezinga le-microvolt anezidingo ezinembayo ezingxenyeni ngesigidi ngasinye.
• I-Biocompatibility nokuphepha kwezinto ezibonakalayo - Izinto ze-substrate, ama-surface finishes, kanye ne-conformal coatings kufanele ihlangabezane nezindinganiso eziqinile zokulawula i-cytotoxicity nokuzinza kwesikhathi eside.

Kungani ama-HDI PCB Afanele Amadivayisi Ezokwelapha

Amakhono we-Miniaturization

Ubuchwepheshe be-HDI PCB buvumela ubuningi bezingxenye ezingeke zisekelwe yimiklamo evamile ngama-microvia, ama-fine-line traces, kanye nezakhiwo ezithuthukisiwe zokwakha. Ubuchwepheshe busekela ama-pitch ezingxenye angaphansi kuka-0.4mm, ngamadayamitha angaphansi kuka-0.15mm, kanye nobubanzi be-trace obusondela kuma-micron angu-50, okwenza kube lula ukwakheka kwesekethe okunezinhlangothi ezintathu okwandisa ubuningi obusebenzayo endaweni ngayinye yeyunithi.

Izicelo zezokwelapha zizuza ngokuqondile kulawa mandla okwenza izinto ezincane. Amasistimu okuqapha i-glucose afinyelela izici ezigqokekayo ngenkathi ehlanganisa ukuxhumana kwe-radiofrequency, ukulinganisa okunembayo kwe-analog, nokusebenza kwe-microcontroller. Ama-pacemakers enhliziyo nama-neurostimulators asebenzisa izakhiwo ze-HDI ukuze afake amajeneretha okwelapha okushaya kwenhliziyo, amasistimu e-telemetry, namasekhethi okulawula amandla ngaphakathi kwamakesi e-titanium anesilinganiso esingaphansi kwama-cubic centimeter angu-50.

Ukusebenza Kagesi Okuthuthukisiwe

Izinzuzo zikagesi zemiklamo ye-HDI PCB yezokwelapha zisukela kubude obuncishisiwe bokuxhumana kanye namajiyometri wendlela yesiginali ethuthukisiwe. Ukulandela umkhondo okufushane phakathi kwezingxenye kunciphisa ukubambezeleka kokusakazeka, kunciphisa inductance ye-parasitic kanye namandla, futhi kunciphisa ukuthambekela kokuphazanyiswa yi-electromagnetic.

Amamojula okuthwebula izithombe anencazelo ephezulu yezinhlelo ze-ultrasound, amakhamera e-endoscopic, kanye nemishini ye-optical coherence tomography athembele ezakhiweni ze-HDI PCB ukuze alondoloze ukwethembeka kwesignali kuzo zonke iziteshi eziningi zedatha ezihambisanayo. Ubuchwepheshe busekela ukuqondisa okulawulwayo kwe-impedance, ukuphathwa kwe-differential pair, kanye namasu okwenza ngcono indiza yomhlabathi agcina ubuqotho besignali ngisho noma amazinga edatha ekhuphuka kanye nobuningi besekethe buqina.

Ukwethenjelwa Okuthuthukisiwe Ngokuklama

Ama-microvias abhojwe nge-laser kanye nezingqimba ezincane ze-dielectric eziwuphawu lokwakhiwa kwe-HDI kunciphisa ukugxilwa kwengcindezi komshini okuba nomthelela ekuhlulekeni kokuhlangana kwe-solder emiklameni evamile yembobo. Izinqubo zokwakheka kwe-lamination ezilandelanayo zisabalalisa ingcindezi kuzo zonke izendlalelo kunokugxilisa imithwalo yemishini ezindaweni ezihlukene zembobo.

Emishinini yezokwelapha efakelwayo edinga amashumi eminyaka empilo yokusebenza, lokhu kuthuthukiswa kokwethembeka kuhumusha ngokuqondile ukuphepha kwesiguli okuthuthukisiwe kanye namazinga okuhlinzwa abuyekeziwe ancishisiwe. Ukuvumelana nezimo komklamo okukhona ekwakhiweni kwezakhiwo zezokwelapha ze-HDI PCB kuhambisana nezidingo eziyinkimbinkimbi zomzila wesignali kuyilapho kugcinwa ubuqotho besakhiwo obudingekayo ukuze kuthembeke isikhathi eside.

Okucatshangelwayo Okubalulekile kanye Nesitaki se-Medical HDI PCB

Ukukhetha I-substrate Yebanga Lezokwelapha

Ukukhethwa kwezinto ezingaphansi kwesisekelo sama-PCB e-HDI yezokwelapha kulinganisela izidingo zokusebenza kukagesi ngokumelene nemikhawulo yokuhambisana kwezinto eziphilayo kanye nezidingo zokuzinza kwemishini.
