Ini ndinovimbisa sei kuvimbika kwevias mune rigid flex circuit board?

Nhanganyaya:

Mune ino blog positi, isu tichaongorora mamwe akakosha matekinoroji uye akanakisa maitiro aunga shandisa kuve nechokwadi chekuvimbika kwevias mune rigid-flex redunhu mabhodhi.
Paunenge uchigadzira mabhodhi edunhu, kuvimbika kunokosha. Chinhu chakakosha chinoda kunyatsotariswa kuvimbika kwevias mune rigid-flex circuit boards. Vias inoita basa rakakosha mukugadzirisa hukama pakati pezvikamu zvakasiyana zvedunhu uye nekuona kuyerera kwakatsetseka kwemasaini emagetsi.

Usati wapinda mune zvese, zvakakosha kuti unzwisise iyo yakakosha pfungwa ye vias. Vias maburi madiki akaboorwa kuburikidza nekudzivirira kwebhodhi redunhu kubvumira kubatana kwemagetsi pakati pezvikamu zvakasiyana. Mune rigid-flex edunhu mabhodhi anosanganisa anochinjika uye akaomarara ma substrates, vias inofanira kugadzirwa kuti imirire kushushikana uye madhiri ane chekuita nekukotama uye kuchinjika.

Kuve nechokwadi chekuvimbika kwevias mune rigid-flex redunhu mabhodhi, hezvino zvimwe zvakakosha zvinotariswa:

1. Kururamisa kuburikidza nekuisa:
Nzvimbo uye kugovera vias zvakakosha pakuchengetedza kuvimbika. Zvakakosha kuisa vias munzvimbo dzedunhu nekukotama kudiki uye kuchinjika. Izvi zvinobatsira kuderedza kushushikana pamusoro vias uye kuvadzivirira kubva kukuvara panguva yeupenyu bhodhi.

2. Kuburikidza nehukuru uye chimiro chechiyero:
Saizi uye chikamu chiyero che via chinokanganisawo kuvimbika kwayo. Diki dhayamita vias haanyanyi kubatwa nemichina kushushikana uye vanonyanya kuramba kukundikana. Pamusoro pezvo, chiyero chechikamu (chiyero chekudzika kusvika padhayamita) chinofanirwa kunge chiri mukati memiganhu inogamuchirwa kudzivirira matambudziko senge plating voids kana makatsemuka.

3. Padhi uye mhete dhizaini:
Dhizaini yepadhi uye mhete yakatenderedza Via inoita basa rakakosha mukuvimbika kwayo. Pedhi yakakwana uye zviyero zvemhete zvinofanirwa kuchengetedzwa kuti zvive nechokwadi chekuti majoini akavimbika ekutengesa uye kubatanidza kwakakodzera kwemagetsi. Mapedhi asina kukura kana marin'i anogona kukonzera kusasimba kwemagetsi kubatana uye matambudziko emagetsi.

4. Kushandisa kuburikidza nemakomba:
Mune rigid-flex circuit boards, zvinokurudzirwa kushandisa nemakomba panzvimbo yemapofu kana kuvigwa vias pese pazvinogoneka. Kuburikidza nemakomba kupa nani mechanical simba uye magetsi connectivity. Vanobvumirawo kuti zvive nyore kuedza uye kuongorora panguva yekugadzira.

5. Kusarudzwa kwezvinhu:
Kusarudza iyo chaiyo zvinhu kune via kwakakosha pakuvimbika kwayo. Zvigadzirwa zvemhando yepamusoro senge electroless copper kana nickel plating (electroless nickel, electroless palladium, kunyudzwa goridhe) zvinogona kuwedzera kusimba uye hupenyu hurefu hwemaburi, kunyanya mumamiriro ezvinhu akaomarara.

6. Kutarisira kupisa:
Yakakodzera yekupisa manejimendi inogona zvakare kuwedzera kuvimbika kwevias mune rigid-flex redunhu mabhodhi. Strategically akaisa thermal vias anobatsira kubvisa kupisa, kuderedza ngozi yekupisa kukuvadza kune bhodhi uye zvinoriumba.

7. Tevedzera zviyero zveindasitiri:
Kutevedzera indasitiri zviyero uye zvakatemwa kwakakosha kuti uve nechokwadi kuburikidza nekuvimbika. Zviyero zvakaita seIPC-2223 zvinopa gwara pamusoro pemagadzirirwo, zvinhu, uye kuita. Kuomerera kune aya zviyero kunovimbisa kuenderana uye kunowedzera kuvimbika kwese kwebhodhi.

8. Kuedza uye kuongorora kwakasimba:
Kunyatsoedza uye kuongororwa kweakaomesesa-flex edunhu mabhodhi, kusanganisira vias, kwakakosha kuona chero zvingangoitika zvisati zvatumirwa. Nzira dzisiri dzekuparadza dzekuyedza dzakadai seX-ray yekuongorora dzinogona kubatsira kuona chero hurema kana kusarongeka mu vias kuitira kuti kugadzirisa kuitwe nekukasira.

Nekushandisa aya akanakisa maitiro uye kufunga, vagadziri vanogona zvakanyanya kunatsiridza kuvimbika kwevias mune rigid-flex redunhu mabhodhi. Izvo zvakakosha kuti ushande nemugadziri ane ruzivo uye kubvunzana nenyanzvi mumunda kuona kuti yakavimbika uye yakasimba kuburikidza nedhizaini yaitwa.

Muchidimbu

Kuvimbika kwevias mune rigid-flex circuit board kwakakosha uye kunoda kunyatsotariswa. Kuburikidza neakakodzera kuburikidza nedhizaini, saizi uye dhizaini, kusarudzwa kwezvinhu, kutonga kwekupisa, kutevedzera indasitiri zviyero uye kuomarara kuyedzwa, dhizaini bhodhi vagadziri vanogona kuve nechokwadi chekubudirira uye kuvimbika kwemapurojekiti avo. Kudyara nguva uye kushanda nesimba mukugadzirisa kuburikidza-gomba madhizaini kunozokonzera kuita zvirinani, kusimba-kusimba-flex mabhodhi.
