Amabhodi Esifunda Aphrintiwe Aphezulu Ezokwelapha: Ikhwalithi Nokwethembeka

Hlola indima ebalulekile yamabhodi esekethe aphrintiwe (ama-PCB) embonini yezokwelapha ngeso likanjiniyela we-PCB oguquguqukayo oneminyaka engu-16. Hlola izixazululo ezintsha kanye nezifundo eziyimpumelelo ezibonisa umthelela wekhwalithi nokuthembeka ekuxazululeni izinselele eziqondene nemboni yekhasimende lezempilo.

Ngenisa

Njengonjiniyela we-PCB onokuhlangenwe nakho onolwazi lweminyaka engu-16 embonini yokukhiqiza ye-PCB eguquguqukayo yezokwelapha, ngibone ukuvela kobuchwepheshe kanye nesidingo esikhulayo samabhodi esekethe aphrintiwe aphrintiwe (ama-PCB) ekhwalithi ephezulu, aguquguqukayo athembekile emkhakheni wezokwelapha. Kulesi sihloko, ngizocubungula indima ebalulekile yama-PCB aguquguqukayo ezinhlelweni zezokwelapha, izinselele amakhasimende embonini abhekana nazo, nokuthi zingathuthukiswa kanjani izixazululo ezintsha ukuze kubhekwane nalezi zinselele. Ngezifundo eziyimpumelelo, ngizobonisa umthelela wekhwalithi nokuthembeka kuma-PCB avumelana nezimo zezokwelapha.

Indima ye-PCB eguquguqukayo ezinhlelweni zezokwelapha

Ama-PCB avumelana nezimo adlala indima ebalulekile kumishini yezokwelapha namathuluzi, ehlinzeka ngokuguquguquka, ukuqina nokuthembeka okudingekayo ezinhlotsheni zezinhlelo zokusebenza. Kusukela kumishini yezokwelapha engagqokwayo kuye kumishini yokuxilonga kanye namadivayisi afakelwayo, isidingo sama-PCB avumelana nezimo wekhwalithi ephezulu siyaqhubeka sikhula. Njengonjiniyela we-PCB oguquguqukayo, ngiyaziqonda izidingo ezihlukile zomkhakha wezokwelapha kanye nesidingo sokunemba, ukusebenza nokuphepha ekwakhiweni nasekukhiqizeni i-PCB.

Izinselele Zemboni Yezokunakekelwa Kwempilo

Imboni yezokwelapha ibhekene nezinselele ezikhethekile ezidinga izixazululo ezenziwe ngezifiso ekukhiqizeni i-PCB eguquguqukayo. Lezi zinselele zifaka izidingo eziqinile zokulawula, ukwenziwa kancane kwedivayisi, ukuhambelana kwe-biocompatibility, kanye nesidingo sokuxhumanisa okunokuminyana okuphezulu. Amakhasimende embonini yezokunakekelwa kwempilo avame ukubhekana nenkinga yokulinganisa ukusebenza nokuthembeka nokuthobela imithetho kanye nokusebenza ngempumelelo kwezindleko. Ngakho-ke, kunesidingo esikhulayo sezixazululo ezintsha nezenziwe ngokwezifiso zokubhekana nalezi zinselele.

Izixazululo ezintsha ze-PCB eguquguqukayo yezokwelapha

Phakathi neminyaka edlule, ulwazi lwami embonini yokukhiqiza ye-PCB eguquguqukayo yezokwelapha luye lwaqhuba ukuthuthukiswa kwezixazululo ezintsha ukuze kuhlangatshezwane nezidingo eziyingqayizivele zamakhasimende emkhakheni wezokwelapha. Ngokusebenzisa izinto ezithuthukisiwe, izinqubo zokukhiqiza ezinembayo, nezinqubo zokuhlola eziqinile, siyakwazi ukuletha ama-PCB ekhwalithi ephezulu, athembekile aguquguqukayo adlula izindinganiso zomkhakha. Lezi zixazululo zenza amakhasimende ethu akwazi ukunqoba izinselele ezihlobene nesiginali yobuqotho, ukuphathwa kwezimo ezishisayo nokuthembeka kumishini yezokwelapha.

Izibonelo: Ukuxazulula Izinselelo Eziqondene Nemboni

I-Case Study 1: I-Miniaturization ne-High-Density Interconnect

Ikhasimende embonini yezokunakekelwa kwempilo lisithinte nezinselele ezihlobene nokwenza kancane kwemishini yokuqapha yezokwelapha egqokekayo. Ikhasimende lalidinga isixazululo se-PCB esivumelana nezimo esingamukela ukuminyana okuphezulu kuyilapho ligcina ukuguquguquka okudingekayo nokuqina. Ngokusebenzisa isofthiwe yokuklama ethuthukisiwe nobuchwepheshe bokukhiqiza obunembayo, sithuthukisa ama-PCB avumelana nezimo ahlangabezana nezidingo zamakhasimende ethu zokwenza izinto ezincane, ukwethembeka, nokusebenza. Ukuhlanganiswa ngempumelelo kwama-PCB aguquguqukayo kumadivayisi ezokwelapha kuthuthukisa ukusebenza nokunethezeka kwesiguli.

Indaba Eyisibonelo 2: Ukuthobela Umthetho kanye Nokuhambisana Kwezinto eziphilayo

Elinye ikhasimende embonini yezokwelapha lifune isisombululo se-PCB esiguquguqukayo somshini wezokwelapha ofakelwayo owawudinga ukuthotshelwa kwezindinganiso eziqinile zokulawula kanye nezidingo ze-biocompatibility. Ithimba lethu lisebenzisana namakhasimende ukuze linqume izinto ezithile kanye nokucatshangelwa kwedizayini okudingekayo ukuze kuhlangatshezwane namazinga okulawula kanye ne-biocompatibility. Ngokuhlolwa okubanzi nokuqinisekisa, sithuthukise ngempumelelo ama-PCB avumelana nezimo ze-biocompatible ahlangabezana nezidingo zokulawula zamakhasimende ethu kuyilapho siqinisekisa ukwethembeka nokuphepha kwamadivayisi afakiwe. Isixazululo senza amakhasimende akwazi ukusheshisa inqubo yokuthuthukisa umkhiqizo futhi athole imvume yokulawula.

Indaba yesi-3: Ubuqotho Besiginali Nokwethenjelwa

Esicwaningweni sesithathu, ikhasimende emkhakheni wezithombe zezokwelapha libhekane nezinselele ezihlobene nobuqotho besignali nokuthembeka ezinhlelweni zokuxilonga zokuxilonga. Ikhasimende lalidinga isisombululo se-PCB esivumelana nezimo esingase sisekele ukudluliswa kwedatha ngesivinini esikhulu kuyilapho sigcina ubuqotho besignali nokwethembeka ezindaweni zokusebenza ezinokhahlo. Ngokudizayina ngokubambisana nokuhlola, siklame i-PCB eyakhelwe inhloso eguquguqukayo ene-impedance elawulwayo nezithuthukisi zobuqotho zesignali. Ukuhlanganisa le PCB eguquguqukayo ezinhlelweni zokucabanga kungathuthukisa ikhwalithi yesithombe, kunciphise ukuphazamiseka kwesignali, futhi kuthuthukise ukwethembeka, ekugcineni kuzuzise ochwepheshe bezempilo neziguli.

Ibhodi Lokuphrinta Lesekhethi Eliphezulu Le-Medical Flexible Printed Prototyping kanye nenqubo yokukhiqiza

Ngokufigqiwe

Kafushane, isidingo semboni yezokwelapha sama-PCB asezingeni eliphezulu, athembekile aguquguqukayo siyaqhubeka nokuqhuba ukuqamba okusha nokusebenzisana phakathi konjiniyela, abakhiqizi namakhasimende. Njengonjiniyela we-PCB oguquguqukayo onolwazi olunzulu embonini yokukhiqiza ye-PCB eguquguqukayo, ngizibonele mathupha ikhwalithi yomthelela nokwethembeka okungaba nakho ekuxazululeni izinselele eziqondene nemboni. Ngocwaningo oluyimpumelelo, sibonisa indima ebalulekile yezixazululo ezintsha ekuhlangabezaneni nezidingo ezihlukile zamakhasimende ethu embonini yezokunakekelwa kwempilo. Ngokubeka phambili ikhwalithi nokwethembeka, sibamba iqhaza ekuthuthukisweni kobuchwepheshe bezokwelapha nokuthuthukisa ukunakekelwa kweziguli.

Emkhakheni ohlale uvela wobuchwepheshe bezokwelapha, ukuphishekela ikhwalithi nokwethembeka kuma-PCB aguquguqukayo kusabalulekile, futhi mina kanye nefekthri yethu iCapel sizibophezele ekuqhubekiseni phambili ukusungula izinto ezintsha kanye nokwenza kahle embonini yokukhiqiza ye-PCB eguquguqukayo yezokwelapha.
