Izinzuzo ze-Flexible PCB kanye ne-Rigid-Flex PCB

Ngokwezinga le-IPC 6013, amabhodi avumelana nezimo ahlukaniswa abe amabhodi anohlangothi olulodwa, anezinhlangothi ezimbili, ezendlalelo eziningi, namabhodi aguquguqukayo aqinile.

Inqubo yokukhiqiza amabhodi aqinile aguquguqukayo ihlanganisa ukulungiswa kwempahla, ukwenza, ukunamathisela, ukubhoboza, ukucwenga, ukusika ibhodi okuguquguqukayo, nokuhlolwa kukagesi.

Inqubo yokukhiqiza amabhodi aqinile-aguquguqukayo iyinketho ekahle yokwakha amasekethe ezimbonini zezokwelapha, zezindiza, ezempi, nezokuxhumana.

Ngenxa yezinzuzo zawo ezifana nokukhanya okulula, ubuningi obukhulu bokuhlanganiswa, kanye nokunciphisa, isidingo sama-PCB anjalo siyanda. Ama-PCB aguquguqukayo nawo anomklamo othuthukisiwe wemishini kanye nokusebenza okuhle kakhulu kukagesi nokushisa. Ukuthandwa kwama-PCB aguquguqukayo kuye kwaholela ekuthuthukisweni kweminye imikhiqizo ehlobene, njenge-HDI flexible PCB, ama-embedded flexible PCB, kanye nama-rigid-flex PCB.

Phakathi kwale mikhiqizo evela kwamanye amazwe, ama-rigid-flex PCB avame ukusetshenziswa embonini yezimoto, yezokwelapha, yezempi, kanye neyezindiza. Ukukhiqizwa kwamabhodi aqinile kuyinqubo ethatha isikhathi, ehilela izinyathelo ezifana nokulungiselela izinto, ukuqopha, ukubhoboza, kanye nokucwebezela, kulandelwe ukukhiqizwa komkhiqizo wokugcina. Lo mhlahlandlela uzohlola ama-flexible PCB futhi uqonde inqubo yokukhiqiza eqinile.

Izinzuzo ze-PCB eziguquguqukayo

Ibhodi lesifunda elenziwe ngezinto eziyisisekelo eziguquguqukayo libizwa ngokuthi i-PCB eguquguqukayo. Ama-PCB aguqukayo (noma amabhodi aguquguqukayo) ayavumelana nezimo, akwazi ukulolongwa ukuze ahlangabezane nezidingo zezinhlelo zokusebenza ezihlukahlukene. Uma kuqhathaniswa namabhodi aqinile endabuko, amabhodi aguquguqukayo anezinzuzo eziningi, okuhlanganisa:

• Usayizi omncane, ongasindi
• Izacile
• I-Miniaturization yamasekethe, ukuminyana okuphezulu komhlangano
• Amaphutha ezintambo ambalwa
• Ukuvumelana nezimo, ezifanele ukwakha amasekhethi agobekayo
• Asikho isidingo sezixhumi zemishini
• Ihambisana nezixhumi ze-3D
• Izinga eliphakeme lenkululeko yokuklama imishini ne-elekthronikhi
• Ubuqotho besignali ephezulu nokuthembeka kwesifunda
• Ukulawulwa okuhle kwe-impedance
• Ububanzi obubanzi bamazinga okushisa okusebenza
• Ukumelana nokushaqeka okunamandla
• Ifanele izindawo ezinokhahlo

Ngaphandle kokuba nazo zonke lezi zinzuzo, ama-PCB aguquguqukayo anezindleko zezinto ezibonakalayo eziphezulu uma kuqhathaniswa namabhodi aqinile noma aqinile. Amabhodi aguquguqukayo ahlanganisa izinzuzo zama-PCB aqinile futhi aguquguqukayo, awenze abe yinzuzo yokukhiqiza isekethe. Okuqukethwe okulandelayo kuzokwethula amabhodi e-rigid-flex kanye nenqubo yokukhiqiza eguquguqukayo.

Amabhodi e-Rigid-flex avame ukusetshenziswa embonini yezimoto, yezokwelapha, yezempi, kanye ne-aerospace.

Iyini i-Rigid-Flexible Boards

Ngokwezinga le-IPC 6013, amabhodi aguquguqukayo ahlukaniswa ngezinhlobo ezahlukene, okuhlanganisa amabhodi anohlangothi olulodwa, anamacele amabili, amabhodi amaningi, kanye namabhodi aguquguqukayo aqinile. Uhlobo 4 ngaphansi kwe-IPC 6013 lukhuluma ngamabhodi aguquguqukayo, ahlanganisa izinzuzo zamabhodi aguquguqukayo naqinile. Angachazwa njengamabhodi ayi-hybrid noma amabhodi aqinile-flex. Amabhodi e-Rigid-flex ahlukaniswe izigaba ezimbili:

1. Uhlobo Lokukhweza Oluguquguqukayo - Lolu hlobo lungagotshwa kanye kuphela phakathi nokufakwa noma ukulungiswa.
2. I-Dynamic Flexible Type - Lolu hlobo lungagotshwa izikhathi eziningi ngesikhathi sokusetshenziswa.

Amabhodi e-Rigid-flex afanele izinhlelo zokusebenza ezidinga usayizi omncane, okungukuthi, isidingo sokuhlanganisa izingxenye eziningi endaweni encane. Idizayinelwe esikhaleni se-3D, amabhodi aqinile-aguquguqukayo anokusebenza kahle okuphezulu kwendawo; zingagotshwa ngokuguquguqukayo noma zigoqwe, zenze kube lula ukwakheka kwesimo esidingekayo ephaketheni lokugcina lomkhiqizo; azidingi ukuxhumana okuningi, zidinga ukunakekelwa okuncane, futhi ziqashelwa kabanzi ngokwethembeka kwazo; amabhodi ama-rigid-flex asetshenziswa kakhulu ezimbonini zezokwelapha, ezokuxhumana ngocingo, kanye nezomkhathi.

Amabhodi e-Rigid-flex afanele izinhlelo zokusebenza ezidinga usayizi omncane, okungukuthi, isidingo sokuhlanganisa izingxenye eziningi endaweni encane.

I-Rigid-flex Manufacturing Process

Ngaphambi kokuthi inqubo yokukhiqiza eguquguqukayo iqale, ukwakheka komklamo we-PCB kudinga ukwenziwa. Uma isakhiwo sesinqunyiwe, inqubo yokukhiqiza eqinile-flex ingaqala.

Inqubo yokukhiqiza eqinile-flex ihlanganisa amasu okukhiqiza amabhodi aqinile futhi aguquguqukayo. Amabhodi aguquguqukayo anqwabelanisa ama-PCB aqinile futhi aguquguqukayo ngokwesendlalelo. Izingxenye zihlanganiswa ezindaweni eziqinile futhi zixhunywe kumabhodi aqinile aseduze ngokusebenzisa izindawo eziguquguqukayo. Ukuxhumana phakathi kwezingqimba kwethulwa ngezimbobo ezipuletiwe.

Inqubo yokukhiqiza eqinile ihlanganisa lezi zinyathelo ezilandelayo:

1. Lungiselela i-substrate: Isinyathelo sokuqala senqubo yokukhiqiza eqinile ukulungisa noma ukuhlanza i-laminate. Kungakhathaliseki ukuthi kukhona i-adhesive coating, ama-laminate anezingqimba zethusi adinga ukuhlanzwa ngaphambi kokufakwa kwezinye izinqubo zokukhiqiza.
2. Ukwenziwa kwephethini: Kwenziwe ngokuphrinta isikrini noma ukuthwebula izithombe.
3. Inqubo yokuhlanganisa: Zombili izinhlangothi ze-laminate ezinephethini yesifunda zicwiliswa ethangini lokunamathisela noma zifafazwe ngesisombululo se-etching agent ukuze kufakwe.
4. Inqubo yokumba ngomshini: Amasistimu okumba anembile noma ukubhola kobuchwepheshe kusetshenziselwa ukubhoboza izimbobo zesekhethi ezidingekayo, amaphedi, namaphethini embobo kumaphaneli okukhiqiza. Ngokwesibonelo, laser drilling ubuchwepheshe.
5. Inqubo ye-Copper plating: Inhloso yenqubo yokucwenga yethusi ukufaka ithusi elidingekayo ngaphakathi kwezimbobo ezipuletiwe ukuze kutholakale ukuxhumana kukagesi phakathi kwezingqimba zebhodi eliguquguqukayo eliqinile.
6. Sebenzisa isendlalelo sekhava: Impahla yesendlalelo sekhava (imvamisa ifilimu ye-polyimide) kanye ne-adhesive kuphrintwa phezu kwebhodi eliqinile-flex ngokuphrinta isikrini.
7. I-Cover layer Lamination: Ukucwenga kwenziwa emazingeni okushisa athile, izingcindezi, kanye nemikhawulo ye-vacuum ukuze kuqinisekiswe ukunamathela okufanele kwesendlalelo sekhava.
8. Faka izimbambo zokuqinisa: Izimbambo ezengeziwe zokuqinisa zingasetshenziswa ngaphambi kwezinqubo ezengeziwe zokugcoba, kuye ngokuthi izidingo zokuklama zebhodi eliguquguqukayo eliqinile.
9. Ukusika kwebhodi okuguquguqukayo: Sebenzisa izindlela zokubhoboza ze-hydraulic noma imimese yokuhlaba ekhethekile ukuze usike ibhodi eliguquguqukayo kusuka kuphaneli yokukhiqiza.
10. Ukuhlolwa nokuqinisekiswa kukagesi: Amabhodi e-Rigid-flex avivinywa ngogesi ngokuya ngemihlahlandlela ye-IPC-ET-652 ukuze kuqinisekiswe ukusebenza kokufakwa, ukuxhuma, ikhwalithi, nokusebenza kwebhodi lesifunda kuhlangabezana nezidingo zokucaciswa kwedizayini. Izindlela zokuhlola zifaka ukuhlolwa kwe-flying probe namasistimu okuhlola igridi.

Inqubo yokukhiqiza eguquguqukayo iyinketho ekahle yokwakha amasekethe ezimbonini zezokwelapha, zezindiza, ezempi, nezokuxhumana ngoba lawa mabhodi esekethe asebenza kahle kakhulu nemisebenzi eqondile, ikakhulukazi ezindaweni ezinokhahlo.

Onjiniyela bavame ukuqinisekisa lesi sihloko kanye nokwakhiwa kwesekethe eguquguqukayo kanye namanothi e-PCB e-transformer yamandla lapho belungiselela ukwakhiwa kwe-PCB noma i-PCBA okuthembekile.
