Ko akaomesesa-flex PCBs anopesana nehunyoro?

Kana zvasvika kune hunyoro uye hunyoro kuramba, mumwe anogona kushamisika kana yakasimba-flex PCBs inogona kusangana nedambudziko iri. Mune ino blog post, isu tichazama zvakadzama mumusoro wenyaya uye tiongorore hunyoro uye hunyoro kuramba kweakaoma-flex PCBs.
Mabhodhi edunhu akadhindwa (PCBs) ndiwo musimboti wemidziyo yemagetsi yemazuva ano, ichipa chikuva chekubatanidza uye kutsigira akasiyana emagetsi zvinhu. PCB tekinoroji yakashanduka nekufamba kwemakore, uye imwe yeiyi kufambira mberi kwave kuri kuiswa kweiyo rigid-flex PCBs.Mabhodhi aya anopa kuchinjika pamwe chete nekutendeseka kwemaitiro emapuranga akaomarara, achiita kuti ave akasiyana-siyana uye akakodzera kune zvakasiyana-siyana zvekushandisa.

Hunyoro uye hunyoro zvinhu zvakajairika zvezvakatipoteredza zvinogona kukanganisa zvakanyanya kuita uye kuvimbika kwemidziyo yemagetsi.Kufumurwa nehunyoro kunogona kukonzera matambudziko akasiyana siyana, kusanganisira ngura, zvikabudura zvemagetsi, uye kushata kwekudzivirira. Naizvozvo, zvakakosha kuve nechokwadi chekuti maPCB anoshandiswa mumidziyo anopokana nezvinhu izvi, kunyanya mumashandisirwo anowanikwa kune hunyoro hwepamusoro.

Rigid-flex PCB ine yakasarudzika chimiro uye ine imwe dhigirii yekunyorova uye humidity kuramba.Aya mabhodhi anowanzo kugadzirwa kubva musanganiswa weanochinjika polyimide akaturikidzana uye akaomesesa FR-4 akaturikidzana, achigadzira yakasimba uye yakavimbika redunhu bhodhi. Iyo polyimide layer inopa kuchinjika, ichibvumira iyo PCB kukotama kana kumonyoroka sezvinodiwa, nepo FR-4 layer inopa kugadzikana kwechimiro.

Chimwe chezvinhu zvikuru mukuvandudza kupikisa kwe-rigid-flex PCBs kune unyoro uye hunyoro ndiko kushandiswa kwepolyimide sechinhu chekutanga.Iyi pfuma inodzivirira kutendeseka kwePCB nekudzivirira iyo polyimide layer kuti isatora unyoro.Kuwedzera, kuchinjika kwepolyimide kunobvumira mapuranga edunhu kuti amire mamwe mamiriro ezvakatipoteredza pasina kukanganiswa nehunyoro.

Pamusoro pezvo, iyo rigid-flex board inogadzirwa ichishandisa tekinoroji yepamberi kuti iwedzere hunyoro hwayo-huchapupu uye hunyoro-humbowo kugona.Aya maitiro anosanganisira kuiswa kwejasi rekudzivirira, senge conformal coating kana sealant, iyo inoshanda sechivharo kurwisa mwando ingress. Aya machira akanyatsogadzirirwa kudzivirira hunyoro kuti husasvike pamagetsi emagetsi uye kukanganisa.

Izvo zvakakosha kucherechedza kuti kunyangwe akaomesesa-flex PCB ane hunyoro hwakakosha uye humidity kuramba, iwo haana kudzivirirwa zvachose kune izvi zvinhu.Mamiriro ezvinhu akanyanyisa, kuratidzwa kwenguva refu kune hunyoro hwepamusoro, kana kubata kusina kunaka kunogona kukanganisa kushanda kwemabhodhi aya.Naizvozvo, izvo zvinodikanwa zvezvakatipoteredza zveimwe application zvinofanirwa kutariswa uye PCB yakagadzirwa zvinoenderana.

Paunenge uchigadzira hunyoro hwekudzivirira kweiyo rigid-flex PCBs, zvinhu zvakati wandei zvinofanirwa kutariswa.Kukwana kwakaringana pakati pezvikamu, kuiswa chisimbiso kwakakodzera kwezvibatanidza uye vias, uye kushandisa zvine hungwaru kwemwando-uchapupu zvinhu ndezvimwe zvezvinhu zvakakosha zvinobatsira kuwedzera PCB kuramba kune izvi zvakatipoteredza.Kushanda pamwe chete neane ruzivo PCB mugadziri anogona kuve nechokwadi chekuti dhizaini yakagadziridzwa. kuti uwane chiyero chinodiwa chekunyorova uye kusagadzikana kwehunyoro.

Muchidimbu, nekuda kwechimiro chayo chakasiyana uye kushandiswa kwezvinhu zvinodzivirira hunyoro senge polyimide, rigid-flex mabhodhi anowanzo kuve neakanaka-ufakazi uye hunyoro-hunyoro zvivakwa.Vanopa mhinduro yakavimbika yemidziyo yemagetsi inogona kuoneswa kune yakaoma mamiriro ezvakatipoteredza. Nekudaro, zvakakosha kufunga nezve izvo zvinodiwa zvechikumbiro uye kugadzira iyo PCB zvinoenderana kuti iwedzere kugona kwayo kutsungirira unyoro uye hunyoro. Nekuita izvi, vagadziri vemidziyo yemagetsi vanogona kuve nehupenyu hurefu uye kuvimbika kwezvigadzirwa zvavo, kunyangwe munzvimbo dzinoda.
