Ko rigid-flex circuit mabhodhi anogadzirwa sei?

Mune ino blog post, isu tichaongorora maitiro ekugadzira akaomesesa-flex edunhu mabhodhi uye tinzwisise kuti anogadzirwa sei.

Rigid-flex circuit mabhodhi, anozivikanwawo seanochinjika akadhindwa edunhu mabhodhi (PCBs), ane mukurumbira muindasitiri yemagetsi nekuda kwekugona kwavo kusanganisa zvakanakira akaomesesa uye anochinjika maPCB.Aya mabhodhi anopa mhinduro dzakasiyana dzezvikumbiro zvinoda kuchinjika uye kusimba.

Kuti tinzwisise maitiro ekugadzira eakaomesesa-flex edunhu mabhodhi, ngatitangei kukurukura kuti chii.Rigid-flex redunhu mabhodhi ane akawanda-layer anochinjika PCB uye yakasimba PCB yekubatanidza. Iyi kusanganiswa inovabvumira kupa iyo inodiwa kuchinjika pasina kupira kutendeseka kwechimiro kunopihwa neakaomesesa mapaneru. Aya mabhodhi akakodzera kushandiswa mumaindasitiri akasiyana-siyana, anosanganisira aerospace, zvekurapa uye zvemotokari, kuti zvishandiswe mumidziyo yakadai semagetsi anopfekeka, ma implants ekurapa uye ma sensors emotokari.

Zvino, ngatitarisei mukugadzira maitiro e-rigid-flex circuit board. Nzira yekugadzira mapuranga aya inosanganisira matanho akawanda, kubva padanho rekugadzira kusvika kumusangano wekupedzisira. Heano matanho akakosha anobatanidzwa:

1. Dhizaini: Chikamu chekugadzira chinotanga nekugadzira dhizaini bhodhi marongero, tichifunga nezve inodiwa chimiro, saizi, uye kushanda.Vagadziri vanoshandisa yakasarudzika software kugadzira edunhu mabhodhi uye kuona kuiswa kwezvikamu uye nzira yekutevera.

2. Kusarudzwa kwezvinhu: Kusarudza chinhu chakakodzera kwakakosha pakugadzirwa kwemabhodhi akaomarara.Inosanganisira kusarudza anochinjika substrates (senge polyimide) uye zvinhu zvakaomarara (senge FR4) zvinokwanisa kumirisana nezvinodiwa zvemakinika kushushikana uye tembiricha shanduko.

3. Kugadzira iyo inogadziriswa substrate: Iyo inogadziriswa substrate inogadzirwa mune imwe nzira isati yabatanidzwa mune rigid-flex circuit board.Izvi zvinosanganisira kuisa conductive layer (kazhinji mhangura) kune yakasarudzwa zvinhu uye wozoishongedza kugadzira dunhu redunhu.

4. Kugadzirwa kweRigid Boards: Zvakare, mapuranga akaoma anogadzirwa achishandisa maitiro ekugadzira PCB.Izvi zvinosanganisira nzira dzakaita sekuchera makomba, kuisa zvidimbu zvemhangura, uye etching kuti iumbe dunhu rinodiwa.

5. Lamination: Mushure flexible bhodhi uye rigid bhodhi vakagadzirirwa, vari laminated pamwe chete kushandisa inokosha adhesive.Iyo lamination process inovimbisa chisungo chakasimba pakati pemhando mbiri dzemapuranga uye inobvumira kuchinjika munzvimbo dzakananga.

6. Circuit pattern imaging: Shandisa photolithography process kuti ufananidze mafambisirwo ematunhu emapuranga anoshanduka uye mabhodhi akaoma pane kunze kwekunze.Izvi zvinosanganisira kuendesa iyo yaunoda pateni pane photosensitive firimu kana kuramba layer.

7. Etching uye plating: Mushure mokunge mufananidzo wedunhu uchifananidzirwa, mhangura yakazaruka inonamirwa kure, ichisiya maitiro edunhu anodiwa.Zvadaro, electroplating inoitwa kusimbisa mitsetse yemhangura uye kupa inodiwa conductivity.

8. Kudhirowa uye nzira: Dhonza maburi mubhodhi redunhu kuti uise chikamu uye kubatanidza.Pamusoro pezvo, kutenderera kunoitwa kugadzira hukama hunodiwa pakati pezvikamu zvakasiyana zvebhodhi redunhu.

9. Musangano wechikamu: Mushure mokunge bhodhi redunhu ragadzirwa, teknolojia yepamusoro yepamusoro kana kuburikidza ne-hole teknolojia inoshandiswa kuisa resistors, capacitors, masangano akabatanidzwa uye zvimwe zvikamu pane rigid-flex circuit board.

10. Kuedza uye Kuongorora: Kana zvikamu zvatengeswa kubhodhi, zvinopinda muyedzo yakaoma uye yekuongorora kuti ive nechokwadi chokuti inoshanda uye inosangana nehutano hwehutano.Izvi zvinosanganisira kuongororwa kwemagetsi, kuongorora kwekuona uye automated optical inspection.

11. Gungano rekupedzisira uye kurongedza: Danho rekupedzisira kuunganidza rigid-flex redunhu bhodhi muchigadzirwa chinodiwa kana mudziyo.Izvi zvinogona kusanganisira zvimwe zvikamu, dzimba uye kurongedza.

Muchidimbu

Iyo yekugadzira maitiro eakaomesesa-flex edunhu mabhodhi anosanganisira akati wandei matanho akaomarara kubva pakugadzira kusvika pagungano rekupedzisira. Iyo yakasarudzika musanganiswa wezvinochinjika uye wakaomarara zvinhu zvinopa kuchinjika kukuru uye kusimba, zvichiita kuti mabhodhi aya akwane kune akasiyana maapplication. Sezvo tekinoroji ichienderera mberi, kudiwa kweakaomesesa-flex edunhu mabhodhi anotarisirwa kukura, uye kunzwisisa maitiro avo ekugadzira kwave kunetsa kune vanogadzira uye mainjiniya ekugadzira.
