Ko Rogers Pcb inogadzirwa sei?

Rogers PCB, inozivikanwawo seRogers Printed Circuit Board, inozivikanwa zvakanyanya uye inoshandiswa mumaindasitiri akasiyana nekuda kwekuita kwayo kwepamusoro uye kuvimbika. Aya maPCB anogadzirwa kubva kune yakakosha zvinhu zvinodaidzwa kuti Rogers laminate, ine yakasarudzika magetsi uye michina zvivakwa. Mune ino blog positi, tichanyura mukati mehukashama hwekugadzira Rogers PCB, tichiongorora maitiro, zvigadzirwa, uye kufunga kunobatanidzwa.

Kuti tinzwisise maitiro ekugadzira maRogers PCB, tinofanira kutanga tanzwisisa kuti mabhodhi aya chii uye kubata zvinorehwa naRogers laminates.MaPCB akakosha zvikamu zvemidziyo yemagetsi, ichipa michina yekutsigira zvimiro uye magetsi ekubatanidza. Rogers PCBs inotsvakwa zvakanyanya mumashandisirwo anoda yakakwirira frequency chiratidzo kutapurirana, kurasikirwa kwakaderera uye kugadzikana. Iwo anoshandiswa zvakanyanya mumaindasitiri akadai seyekufonera, aerospace, zvekurapa uye zvemotokari.

Rogers Corporation, ane mukurumbira wekupa zvigadziriso zvemidziyo, akagadzira Rogers laminates kuti ashandiswe mukugadzira yakakwirira-inoshanda edunhu mabhodhi. Rogers laminate chinhu chakaumbwa chine ceramic-yakazadzwa yakarukwa fiberglass jira ine hydrocarbon thermoset resin system. Musanganiswa uyu unoratidza zvakanakisa zvemagetsi zvimiro senge yakaderera dielectric kurasikirwa, yakakwira yekupisa conductivity uye yakanakisa dimensional kugadzikana.

Zvino, ngatitarisei muRogers PCB yekugadzira maitiro:

1. Dhizaini marongero:

Nhanho yekutanga mukugadzira chero PCB, kusanganisira Rogers PCBs, inosanganisira kugadzira dhizaini marongero. Mainjiniya anoshandisa yakasarudzika software kugadzira schematics yemabhodhi edunhu, kuisa uye kubatanidza zvikamu zvakakodzera. Ichi chikamu chekutanga chekugadzira chakakosha pakuona kushanda, kuita, uye kuvimbika kwechigadzirwa chekupedzisira.

2. Kusarudzwa kwezvinhu:

Kana dhizaini yapera, kusarudzwa kwezvinhu kunova kwakakosha. Rogers PCB inoda kusarudza yakakodzera laminate material, uchifunga nezvezvinhu zvakadai sezvinodiwa dielectric constant, dissipation factor, thermal conductivity, uye mechanical properties. Rogers laminates anowanikwa mumhando dzakasiyana-siyana kuti asangane nezvinodiwa zvakasiyana zvekushandisa.

3. Cheka laminate:

Nekugadzirwa uye kusarudzwa kwezvinhu kwapera, danho rinotevera nderekucheka Rogers laminate kusvika saizi. Izvi zvinogona kuwanikwa uchishandisa akasarudzika ekucheka maturusi senge CNC michina, kuve nechokwadi chemipimo chaiyo uye kudzivirira chero kukuvadzwa kwezvinhu.

4. Kuchera nekudira mhangura:

Panguva ino, maburi anodonhedzwa mu laminate zvinoenderana nedhizaini yedunhu. Makomba aya, anonzi vias, anopa kubatanidza magetsi pakati pezvikamu zvakasiyana zvePCB. Makomba akacherwa anobva aputirwa mhangura kuti agadzirise conductivity uye kuvandudza kutendeseka kwemaitiro eiyo vias.

5. Kudhirowa kwedunhu:

Mushure mekuchera, chidimbu chemhangura chinoiswa kune laminate kugadzira nzira dzekufambisa dzinodiwa kuti PCB ishande. Iyo bhodhi-yakapfeka bhodhi yakaputirwa nechiedza-sensitive material inonzi photoresist. Iyo yedunhu dhizaini inozoendeswa kune photoresist vachishandisa hunyanzvi hunyanzvi senge photolithography kana yakananga imaging.

6. Etching:

Mushure mekugadzirwa kwedunhu kudhindwa pane photoresist, kemikari etchant inoshandiswa kubvisa yakawandisa mhangura. Iyo etchant inonyungudutsa mhangura isingadiwi, ichisiya kumashure kweinodiwa dunhu patani. Iyi nzira yakakosha pakugadzira iyo conductive traces inodiwa kune PCB's magetsi ekubatanidza.

7. Layer alignment uye lamination:

Kune akawanda-layer Rogers PCBs, iwo ega akaturikidzana akanyatso kurongeka uchishandisa yakasarudzika michina. Aya akaturikidzana uye akaiswa laminated pamwe chete kuti aite akabatana chimiro. Kupisa uye kudzvanywa kunoiswa kune mumuviri uye nemagetsi kubatanidza maseru, kuve nechokwadi chekufambisa pakati pavo.

8. Electroplating uye pamusoro pekurapa:

Kuchengetedza kutenderera uye kuve nechokwadi chekuvimbika kwenguva refu, iyo PCB inopinda muplating uye pamusoro pekurapa maitiro. Mutsetse wakatetepa wesimbi (kazhinji goridhe kana tin) unonamirwa panzvimbo yemhangura iri pachena. Ichi chivharo chinodzivirira kuora uye chinopa nzvimbo yakanaka kune solder components.

9. Solder mask uye sirika screen application:

Iyo PCB yepamusoro yakaputirwa ne solder mask (kazhinji yakasvibira), ichisiya chete nzvimbo dzinodiwa dzekubatanidza chikamu. Iyi yekudzivirira inochengetedza inoteedzera mhangura kubva kune zvakatipoteredza zvinhu zvakaita sehunyoro, guruva, uye netsaona kubata. Uye zvakare, silkscreen layers inogona kuwedzerwa kumaka chikamu dhizaini, mareferenzi madhizaini uye rumwe ruzivo rwakakodzera pane PCB pamusoro.

10. Kuedza uye Kudzora Hunhu:

Kana iyo nzira yekugadzira yapera, chirongwa chekuyedza uye chekuongorora chinoitwa kuti ive nechokwadi chekuti PCB iri kushanda uye inosangana nemaitiro ekugadzira. Maedzo akasiyana akadai sekuenderera mberi kuyedza, yakakwira voltage kuyedzwa uye impedance bvunzo inosimbisa kuvimbika uye kuita kweRogers PCB.

Muchidimbu

Kugadzirwa kweRogers PCBs kunosanganisira maitiro ane hunyanzvi anosanganisira dhizaini uye dhizaini, kusarudzwa kwezvinhu, kucheka laminates, kuchera uye kudira mhangura, dunhu rekufungidzira, etching, layer alignment uye lamination, plating, kugadzirira kwepamusoro, solder mask uye skrini yekudhinda maapplication pamwe nekunyatso. kuedza uye kutonga kwehutano. Kunzwisisa kuomesesa kweRogers PCB kugadzira kunosimbisa kutarisirwa, kunyatsoita, uye hunyanzvi hunobatanidzwa mukugadzira aya mabhodhi epamusoro-soro.
