Usati wagadzira rakadhindwa redunhu bhodhi, zvinodikanwa kuona kana kushandisa imwe-layer kana akawanda-layer PCB. Mhando mbiri dzekugadzira dzakajairika. Saka ndeipi mhando yakakodzera purojekiti yako? Chii chakasiyana? Sezvinoreva zita, rimwe-layer bhodhi rinongova nechikamu chimwe chete chezvinyorwa zvepasi, zvinonziwo substrate, nepo PCB yakawanda iine akati wandei.
Zvakanakira uye kushandiswa kweimwe-layer board
Single-layer boards dzimwe nguva anodaidzwa kuti single-sided boards. Kazhinji kutaura, kune zvikamu kune rimwe divi rebhodhi uye mhangura inoteedzera kune rimwe divi. Iyo single-layer board ine base layer, conductive simbi layer, uye inodzivirira solder mask. Firimu uye sirika screen kuumbwa.

Zvakanakira uye zvakaipira zve single-layer PCB
Zvakanakira: mutengo wakaderera, dhizaini iri nyore uye kugadzirwa, ipfupi nguva yekuendesa
Kukanganisa: Pamapurojekiti akaoma, kunyanya kana nhamba yezvikamu zvakakura, kana hukuru hunodiwa huri huduku, pani imwe chete haigoni kubata simba rekushanda rakaderera, hukuru hukuru, uye uremu hukuru.

Single layer PCB application
Single panel yave sarudzo yakasarudzika kune akasiyana zvigadzirwa zvemagetsi nekuda kwemutengo wakaderera uye nyore kugadzira. Kunyange zvazvo mabhodhi e-multi-layer board ari kuwedzera uye anonyanya kufarirwa sezvo teknolojia yemagetsi inowedzera uye yakaoma, mabhodhi e-single-layer achiri kushandiswa zvakanyanya. Ivo vanowanzo kuoneka mumidziyo ine basa rimwechete uye haidi kuchengetedza yakawanda data kana kuwana network.
Single-layer PCBs anowanzo shandiswa mumidziyo midiki yemumba (senge michina yekofi). Ndiwo zvakare PCB inoshandiswa mumakarukureta mazhinji, maredhiyo, maprinta uye mwenje we LED. Zvishandiso zvakareruka zvekuchengetera zvakaita seyakasimba-nyika madhiraivha anowanzo shandisa single-sided PCBs, sezvinoita zvinhu zvakaita semagetsi emagetsi uye akawanda akasiyana masensor.
Zvakanakira uye mashandisirwo eakawanda-layer board
Multi-layer PCBs anogadzirwa nematatu kana anopfuura maviri-mativi mabhodhi akaturikidzana pamusoro peimwe. Kazhinji, nhamba yezvikamu zvebhodhi re multilayer kazhinji inenge nhamba yezvikamu, pakati pe 4 ne 12 zvidimbu. Wadii kushandisa nhamba isinganzwisisike yezvikamu? Nekuti iyo isinganzwisisike nhamba yezvikamu zvinokonzeresa matambudziko senge warpage uye kukanganisa mushure mekugadzira.
Kune masimbi ekuitisa pamativi ese ega ega substrate layer pane multilayer board. A adhesive yakakosha inoshandiswa kubatanidza mapuranga aya pamwechete, uye pane insulating material pakati pebhodhi rimwe nerimwe. Kumucheto kwekunze kweiyo multilayer board ndiyo solder mask.
Multilayer mapuranga anoshandisa kuburikidza nemakomba kuita akasiyana akaturikidzana kutaurirana. Kuburikidza nemakomba anowanzo kukamurwa muzvikamu zvitatu:
Kuburikidza negomba: kuburikidza nechikamu chimwe nechimwe chebhodhi redunhu;
bofu gomba: batanidza kunze kwekunze kune mukati memukati;
Kuvigwa kuburikidza ne: Batanidza mativi maviri emukati, uye haaonekwe kubva kunze.

Zvakanakira uye zvakaipira zve multilayer PCB
Zvakanakira: kukwanisa kubata mamwe mabasa akaomarara, mhando yepamusoro, simba rakakura, kugona kukuru kwekushanda uye kukurumidza kukurumidza, kusimba kwakawedzera, hukuru hudiki uye huremu huremu.
Kukanganisa: mutengo wepamusoro, dhizaini yakaoma uye kugadzirwa, nguva yakareba yekutumira, kugadzirisa kwakaoma.

Multilayer PCB application
Nekufambira mberi kwehunyanzvi, multilayer PCBs dzave kuwanda uye kuwanda. Midziyo yakawanda yemagetsi nhasi ine mabasa akaomarara uye madiki madiki, saka akawanda akaturikidzana anofanirwa kushandiswa pamabhodhi avo edunhu.
Multilayer akadhindwa edunhu mabhodhi anoonekwa muzvikamu zvakawanda zvekombuta, kusanganisira mamabhodhi nemaseva. Kubva pamalaptops uye mahwendefa kusvika kumafoni ekuchenjera uye mawachi akangwara. Nharembozha dzinowanzoda dzinenge gumi nembiri. Zvimwe zvigadzirwa hazvina kuomarara semafoni ekuchenjera, asi zvakanyanya kuomarara kune rimwe-sided akadhindwa edunhu mabhodhi, kazhinji anoshandisa 4 kusvika 8 akaturikidzana. Zvakadai semicrowave oveni uye air conditioners.
Mukuwedzera, nekuda kwekuvimbika, hukuru hudiki uye dhizaini yakareruka inodiwa nemidziyo yekurapa, ivo vanogona kazhinji kumhanya pabhodhi rine anopfuura matatu akaturikidzana. Multilayer akadhindwa edunhu mabhodhi anoshandiswawo mumachina eX-ray, mamonitor emoyo, CAT scanning michina uye mamwe akawanda maapplication.
Maindasitiri emotokari uye aerospace ari kuwedzerawo kushandisa zvinhu zvemagetsi zvinogara uye zvisingaremi, uye izvi zvinowanzo shandisa mabhodhi akawanda. Izvi zvikamu zvinofanirwa kukwanisa kumira kupfeka, kupisa kwakanyanya uye mamwe mamiriro akaomarara. Pa-bhodhi makomputa, masisitimu eGPS, ma sensors einjini, uye ma switch emwenje emusoro anowanzo shandisa mabhodhi akawanda.
Maitiro ekuona kudiwa kwe-single-layer kana akawanda-layer PCB
Kuti uone kana purojekiti yako inoda imwe-layer kana multilayer yakadhindwa redunhu bhodhi, unofanirwa kufunga nezvezvinodiwa zvepurojekiti uye mhando yakakodzera kwazvo. Zvibvunze mibvunzo mishanu inotevera:
1. Ndeipi nhanho yekushanda yandinoda? Kana zvakanyanya kuoma, zvidimbu zvakawanda zvinogona kudiwa.
2. Ndeipi yakakura saizi yebhodhi? Multilayer mabhodhi anogona kugarisa mamwe mabasa munzvimbo diki.
3. Kusimba kunopihwa pekutanga here? Kana zvakadaro, shandisa zvidimbu zvakawanda.
4. Ndeipi bhajeti yangu? Kune imwe bhajeti ine mwero, single-layer board inoshanda zvakanyanya.
5. Ndichada PCB nokukurumidza sei? Kuenzaniswa nemapuranga akawanda akadhindwa edunhu mabhodhi, single-layer yakadhindwa edunhu mabhodhi ane ipfupi yekutungamira nguva.
