Ndezvipi zvinhu zvinoshandiswa mune rigid-flex Boards?

Imwe mhando yebhodhi redunhu iri kuwedzera kuve yakakurumbira muindasitiri yemagetsi ndiyorigid-flex board.

Kana zvasvika kumidziyo yemagetsi senge masmartphones nemalaptops, kushanda kwemukati kwakangokosha sekunze kwekunze. Izvo zvikamu zvinoita kuti zvishandiso izvi zvishande zvinowanzovanzwa pasi pematanho ebhodhi redunhu kuti ive nechokwadi chekushanda kwavo uye kusimba. Asi ndezvipi zvinhu zvinoshandiswa mune izvi zvitsva zvedunhu mabhodhi?

Rigid-flex PCBinosanganisa mabhenefiti eakaomarara uye anochinjika edunhu mabhodhi, achipa yakasarudzika mhinduro yemidziyo inoda musanganiswa wesimba remagetsi uye kuchinjika. Aya mabhodhi anonyanya kubatsira mumashandisirwo anosanganisira akaomesesa matatu-dimensional dhizaini kana michina inoda kugara ichipeta kana kukotama.

Ngatitarisei zvakanyanya pazvinhu zvinowanzoshandiswa mukuoma-flex PCB kuvaka:

1. FR-4: FR-4 igirazi-inorebesa girazi-yakasimbiswa epoxy laminate zvinhu zvinoshandiswa zvakanyanya muindasitiri yemagetsi. Ndiyo inonyanya kushandiswa substrate zvinhu mune rigid-flex PCBs. FR-4 ine yakanakisa magetsi ekudzivirira zvivakwa uye yakanaka mechani simba, ichiita kuti ive yakakodzera kune dzakaomarara zvikamu zvemabhodhi edunhu.

2. Polyimide: Polyimide i-high-temperature-resistant polymer iyo inowanzoshandiswa sechinhu chinogadziriswa che substrate mumapuranga akaoma-flex. Iyo ine yakanakisa kupisa kugadzikana, magetsi ekudzivirira zvivakwa uye mechanical flexibility, ichibvumira kuti irambe ichiramba ichikotama nekukotama pasina kukanganisa kuvimbika kwebhodhi redunhu.

3. Mhangura: Mhangura ndiyo huru conductive zvinhu mu rigid-flex boards. Inoshandiswa kugadzira conductive traces uye inopindirana inobvumira magetsi kuyerera pakati pezvikamu pabhodhi redunhu. Mhangura inosarudzwa nekuda kwepamusoro conductivity, yakanaka solderability uye mari-inoshanda.

4. Adhesive: Adhesive inoshandiswa kubatanidza zvidimbu zvakasimba uye zvinoshanduka zvePCB pamwe chete. Izvo zvakakosha kuti usarudze chinonamira chinogona kumirisana nekupisa uye mekiniki kushushikana kunosangana panguva yekugadzira maitiro uye hupenyu hwemidziyo. Thermoset adhesives, senge epoxy resins, anowanzo shandiswa mune rigid-flex PCBs nekuda kwekunaka kwekubatanidza zvivakwa uye yakakwirira tembiricha kuramba.

5. Coverlay: Chivharo chekuvhara chivharo chekudzivirira chinoshandiswa kuvhara chikamu chinoshanduka chebhodhi redunhu. Iyo inowanzo gadzirwa kubva ku polyimide kana yakafanana inochinjika zvinhu uye inoshandiswa kuchengetedza yakatetepa zviteshi uye zvikamu kubva kune zvakatipoteredza zvinhu zvakaita semwando neguruva.

6. Solder mask: Iyo solder mask indanda yekudzivirira yakavharwa pane yakaoma chikamu chePCB. Inobatsira kudzivirira solder bridging uye magetsi mashorts uku ichipawo insulation uye corrosion dziviriro.

Izvi ndizvo zvinhu zvikuru zvinoshandiswa mukuoma-inoshanduka PCB kuvaka.Nekudaro, zvakakosha kucherechedza kuti iyo chaiyo zvinhu uye zvimiro zvavo zvinogona kusiyana zvichienderana nekushandiswa kwebhodhi uye kuita kwaunoda. Vagadziri vanowanzo gadzirisa zvinhu zvinoshandiswa mune rigid-flex PCBs kuti isangane nezvinodiwa zvechishandiso chavanoshandisa.

Muchidimbu,rigid-flex PCBs innovation inoshamisa muindasitiri yemagetsi, inopa musanganiswa wakasarudzika wesimba remagetsi uye kuchinjika. Zvishandiso zvinoshandiswa zvakaita seFR-4, polyimide, mhangura, zvinonamira, zvakavharika, uye masiki ekutengesa zvese zvinotora basa rakakosha mukushanda nekusimba kwemabhodhi aya. Nekunzwisisa zvinhu zvinoshandiswa muakaomesesa-flex PCBs, vagadziri nevagadziri vanogona kugadzira zvemhando yepamusoro, zvakavimbika zvemagetsi zvigadzirwa zvinosangana nezvinodiwa nenyika yanhasi inofambiswa nehunyanzvi.
