Tengani wokamba wa Bluetooth monga chitsanzo kuti muphatikize chidziwitso choyambirira cha PCB kapangidwe kake kothandiza, ndikufotokozera magwiridwe antchito ndi luso ndi luso la mapulogalamu a PCB kudzera muntchito. Maphunzirowa aphunzira chidziwitso chokhudzana ndi zingwe za PCB pofotokozera mwachidule malingaliro ndi mfundo pakupanga zingwe.

Mfundo zazikuluzikulu pa kafukufukuyu:

1. Kuwunikira mwachidule ndi mfundo zake

Zofunikira zazikulu za 2.PCB

3. Impedance ulamuliro wa PCB Kulumikizana

Mavuto ophunzirira munthawi imeneyi:

1. Kuwunikira mwachidule ndi mfundo zake

2. Impedance ulamuliro wa PCB Kulumikizana

1. Kuwunikira mwachidule ndi mfundo zake

Mumapangidwe achikhalidwe a PCB, zingwe zomwe zili pa bolodi zimangokhala ngati chonyamulira cholumikizira ma siginolo, ndipo mainjiniya a PCB safunikira kulingalira magawo ogawa magawano.

Ndikukula kwamsika kwa mafakitale amagetsi, deta yomwe imameza kuchokera ku ma megabyte ochepa pa nthawi yayitali, ma megabytes makumi mpaka pamlingo wa 10Gbit / s yabweretsa chitukuko chofulumira cha chiphunzitso chothamanga kwambiri, kulumikizana kwa PCB sichinthu chonyamula cholumikizira chophweka , koma kuchokera ku chiphunzitso cha mzere wamagetsi kuti muwone momwe magawo amagawidwe osiyanasiyana

Nthawi yomweyo, zovuta ndi kuchuluka kwa PCB kukuwonjezeka nthawi yomweyo, kuyambira pa pulani yodziwika bwino mpaka pakapangidwe kakang’ono ka mabowo kupita kumalo osanjikiza akhungu, palinso zotsekera m’manda, zotengera m’manda, kapangidwe kanyumba kakang’ono ka PCB kuti kubweretsa zovuta zazikulu nthawi yomweyo, amafunikiranso kapangidwe ka PCB wopanga mozama kumvetsetsa kwamachitidwe amachitidwe a PCB ndikukonzekera.

Ndi kukula kwa liwilo komanso kachulukidwe ka PCB, akatswiri opanga ma PCB akukhala ofunikira kwambiri pakupanga zida zamagetsi, pomwe zovuta za kapangidwe ka PCB zikuchulukirachulukira, ndipo opanga mapangidwe amafunika kudziwa zochulukirapo.

Awiri, mtundu wa waya wa PCB

Mitundu yolumikizira pa bolodi ya PCB imaphatikizapo chingwe cha ma siginolo, magetsi ndi waya wapansi. Pakati pawo mzere wa ma waya ndi ulusi wofala kwambiri, mtunduwo umakhala wochulukirapo. Mukhale ndi mono line molingana ndi mawonekedwe a zingwe, mzere wosiyana.

Malinga ndi kapangidwe kake ka zingwe, imatha kugawidwa mu mzere wa riboni ndi mzere wa microstrip.

Iii. Kudziwa kwakukulu kwa zingwe za PCB

Kulumikizana kwa General PCB kuli ndi izi:

(1) QFP, SOP ndi mapaketi ena amakona anayi akuyenera kutulutsidwa kuchokera ku PIN (makamaka pogwiritsa ntchito mawonekedwe).

(2) Nsalu (1) QFP, SOP ndi mapaketi ena amiyadi yamakona anayi kuchokera pa waya, kuchokera ku PIN Center (makamaka ogwiritsa ntchito mawonekedwe. Mtunda kuchokera pamzere mpaka m’mphepete mwa mbale siyikhala yochepera 20MIL.

Chidziwitso: pa chithunzi pamwambapa, chofiira ndi OUTLINE ya chimango chakunja cha bolodi, ndipo chobiriwiracho ndiye njira yolumikizira dera lonse lolumikizira (Routkeepin ndiyoposa 20mil indent poyerekeza ndi OUTLINE).

Chidziwitso: Mbali iyi ya bolodi imaphatikizaponso kutsegula kwazenera, mphero, makwerero, mphero yocheperako potchera makina odulira zithunzi m’mphepete.

)

(4) Kulumikizana sikungakhale ndi zolakwika ku DRC, kuphatikiza zolakwika zofananira za DRC, kupatula mapangidwe oyenerana, kupatula zolakwika za DRC zomwe zimadza chifukwa chodzipeka zokha.)

(5) Palibe netiweki yosalumikizidwa pambuyo pa kapangidwe ka PCB, ndipo netiweki ya PCB iyenera kukhala yogwirizana ndi chithunzi cha dera.

Saloledwa kupita ku Dangline.

(7) Ngati zikuwonekeratu kuti mapadi osagwira ntchito safunika kusungidwa, ayenera kuchotsedwa pa fayilo yojambulira.

(8) Tikulimbikitsidwa kuti tisayambe theka la mtunda kuchokera ku 2MM yayikulu ya nsomba

(9) Tikulimbikitsidwa kugwiritsa ntchito zingwe zamkati zazingwe zamagetsi

(10) Ndikulimbikitsidwa kuti ndege yofananira yamphamvu kapena ndege yapansi yapa siginecha yothamanga kwambiri isungidwe momwe ingathere

(11) Tikulimbikitsidwa kuti zingwezo zigawidwe mofanana. Mkuwa uyenera kuyikidwa m’malo akulu opanda zingwe, koma kuwongolera kwa ma impedance sikuyenera kukhudzidwa

(12) Ndikulimbikitsidwa kuti zingwe zonse zimayimitsidwa, ndipo Angle yolowera ndi 45 °

(13) Tikulimbikitsidwa kuti tileke mizere yama siginolo kuti isadzipangire yokha ndi kutalika kwa mbali 200ML m’magawo oyandikana

(14) Ndikulimbikitsidwa kuti kuwongolera kwa zingwe zamagawo oyandikana ndikapangidwe kazolowera

Chidziwitso: Kulumikizana kwa zigawo zoyandikana kuyenera kupewedwa m’njira yomweyo kuti muchepetse kuyankhulana kwapakati pazigawo. Ngati sizingapeweke, makamaka ngati chiwonetserocho chikukwera, ndegeyo iyenera kuganiziridwa kuti ipatula zingwe zilizonse, ndipo chizindikirocho chizipatula mzere uliwonse.

4. Impedance ulamuliro wa PCB Kulumikizana

Kufotokozera: Kutambalala kwa mzere pakapangidwe ka PCB kumagawika magawo awiri, m’lifupi mwake ndikutambalala kwapansi.

Chithunzi chojambulidwa cha kuwerengera kwa impedance kwa mzere umodzi wokhazikika wa microstrip:

Chithunzi chojambulidwa cha ma impedance owerengera masiyanidwe amizere microstrip mzere:

Chithunzi chazithunzi cha kuwerengera kwa impedance kwa mzere wazizindikiro wa chizindikiro chimodzi:

Chithunzithunzi cha chiwerengerochi cha kuwerengera kwa ma impedance amtundu wa chizindikiro chosiyanitsa:

Chithunzi chojambulidwa cha ma impedance owerengera ma microstrip line amodzi (okhala ndi waya wa coplanar):

Chithunzi chojambulidwa cha ma impedance owerengera masiyanidwe amizere microstrip mzere (wokhala ndi waya wapa coplanar):

Uku ndikuwunika mwachidule ndi mfundo za ALLEgro za mapulogalamu a PCB.
