Kodi Rogers Pcb imapangidwa bwanji?

Rogers PCB, yomwe imadziwikanso kuti Rogers Printed Circuit Board, ndiyotchuka kwambiri komanso imagwiritsidwa ntchito m'mafakitale osiyanasiyana chifukwa chakuchita bwino komanso kudalirika kwake. Ma PCB awa amapangidwa kuchokera kuzinthu zapadera zotchedwa Rogers laminate, zomwe zimakhala ndi magetsi komanso makina apadera. Mu positi iyi yabulogu, tilowa muzovuta za kupanga kwa Rogers PCB, ndikuwunika njira, zida, ndi malingaliro omwe akukhudzidwa.

Kuti timvetsetse njira yopangira ma Rogers PCB, choyamba tiyenera kumvetsetsa zomwe matabwawa ali ndi kumvetsetsa zomwe Rogers laminates amatanthauza.Ma PCB ndi zigawo zofunika kwambiri pazida zamagetsi, kupereka zida zothandizira zamakina ndi kulumikizana kwamagetsi. Ma Rogers PCB amafunidwa kwambiri pamapulogalamu omwe amafunikira kufalikira kwa ma frequency apamwamba, kutayika kochepa komanso kukhazikika. Amagwiritsidwa ntchito kwambiri m'mafakitale monga telecommunication, ndege, zamankhwala ndi zamagalimoto.

Rogers Corporation, wodziwika bwino wopereka mayankho azinthu, adapanga ma Rogers laminates makamaka kuti agwiritsidwe ntchito popanga ma board oyendera bwino kwambiri. Rogers laminate ndi chinthu chophatikizika chopangidwa ndi nsalu yopangidwa ndi ceramic yodzaza ndi fiberglass yokhala ndi hydrocarbon thermoset resin system. Kusakaniza kumeneku kumawonetsa zinthu zabwino kwambiri zamagetsi monga kuchepa kwa dielectric, kutsika kwamafuta komanso kukhazikika kwabwino kwambiri.

Tsopano, tiyeni tifufuze njira yopangira Rogers PCB:

1. Kapangidwe kake:

Gawo loyamba popanga PCB iliyonse, kuphatikiza ma Rogers PCBs, kumaphatikizapo kupanga masanjidwe adera. Akatswiri amagwiritsa ntchito mapulogalamu apadera kuti apange schematics ya matabwa ozungulira, kuyika ndi kulumikiza zigawo moyenera. Gawo loyambirira lopangali ndilofunika kwambiri pozindikira magwiridwe antchito, magwiridwe antchito, ndi kudalirika kwa chinthu chomaliza.

2. Kusankha zinthu:

Mapangidwewo akamaliza, kusankha zinthu kumakhala kofunika kwambiri. Rogers PCB imafuna kusankha zinthu zoyenera za laminate, poganizira zinthu monga dielectric constant, dissipation factor, matenthedwe matenthedwe, ndi makina. Ma Rogers laminates amapezeka m'makalasi osiyanasiyana kuti akwaniritse zofunikira zosiyanasiyana.

3. Dulani laminate:

Ndi mapangidwe ndi kusankha zinthu zatha, sitepe yotsatira ndikudula Rogers laminate kukula. Izi zitha kuchitika pogwiritsa ntchito zida zapadera zodulira monga makina a CNC, kuwonetsetsa miyeso yolondola ndikupewa kuwonongeka kwa zinthuzo.

4. Kubowola ndi kuthira mkuwa:

Panthawiyi, mabowo amabowoleredwa mu laminate molingana ndi kapangidwe ka dera. Mabowo awa, otchedwa vias, amapereka kulumikizana kwamagetsi pakati pa zigawo zosiyanasiyana za PCB. The mokhomerera mabowo ndiye mkuwa yokutidwa kukhazikitsa madutsidwe ndi kusintha structural umphumphu wa vias.

5. Kujambula mozungulira:

Pambuyo pobowola, wosanjikiza mkuwa umagwiritsidwa ntchito pa laminate kulenga conductive njira zofunika kuti PCB ntchito. Bolodi lopangidwa ndi mkuwa limakutidwa ndi zinthu zosamva kuwala zotchedwa photoresist. Mapangidwe ozungulira amasamutsidwa ku photoresist pogwiritsa ntchito njira zapadera monga photolithography kapena kujambula mwachindunji.

6. Kujambula:

Mapangidwe a dera akasindikizidwa pa photoresist, mankhwala etchant amagwiritsidwa ntchito kuchotsa mkuwa wochuluka. The etchant amasungunula mkuwa wosafuna, kusiya m'mbuyo ankafuna dera chitsanzo. Njirayi ndiyofunikira kwambiri popanga ma conductive omwe amafunikira kulumikizana kwamagetsi a PCB.

7. Kuyanjanitsa ndi kuyanika:

Kwa ma PCB a Rogers amitundu yambiri, zigawozo zimalumikizidwa ndendende pogwiritsa ntchito zida zapadera. Zigawozi zimayikidwa pamodzi ndi laminated pamodzi kuti zikhale zogwirizana. Kutentha ndi kupanikizika kumagwiritsidwa ntchito pomangirira zigawozo mwakuthupi ndi zamagetsi, kuonetsetsa kuti madulidwe pakati pawo ndi abwino.

8. Electroplating ndi mankhwala pamwamba:

Kuteteza zozungulira ndikuwonetsetsa kudalirika kwa nthawi yayitali, PCB imakumana ndi njira yopangira plating ndi pamwamba. Chitsulo chopyapyala (kawirikawiri golide kapena malata) chimakutidwa pamwamba pa mkuwa woonekera. Kuphimba uku kumalepheretsa dzimbiri ndipo kumapereka malo abwino opangira zida za soldering.

9. Chigoba cha solder ndi pulogalamu ya silika:

Malo a PCB amakutidwa ndi chigoba cha solder (nthawi zambiri chobiriwira), ndikusiya malo ofunikira kuti agwirizane ndi chigawocho. Chotchinga chotetezachi chimateteza mikwingwirima yamkuwa kuzinthu zachilengedwe monga chinyezi, fumbi, ndi kukhudzana mwangozi. Kuphatikiza apo, masiketi a silkscreen atha kuwonjezeredwa kuti awonetse masanjidwe azinthu, okonza mareferensi ndi zina zofunikira pa PCB.

10. Kuyesa ndi Kuwongolera Ubwino:

Ntchito yopangira ikamalizidwa, pulogalamu yoyesa ndikuwunika imachitika kuti zitsimikizire kuti PCB ikugwira ntchito komanso ikugwirizana ndi kapangidwe kake. Mayesero osiyanasiyana monga kuyesa kupitiliza, kuyesa kwamagetsi apamwamba komanso kuyesa kwa impedance kumatsimikizira kukhulupirika ndi magwiridwe antchito a Rogers PCB.

Powombetsa mkota

Kupanga ma PCB a Rogers kumaphatikizapo njira yosamala yomwe imaphatikizapo mapangidwe ndi masanjidwe, kusankha zinthu, kudula laminates, kubowola ndi kutsanulira mkuwa, kujambula kwa dera, etching, kuyanjanitsa ndi kuyanika, plating, kukonzekera pamwamba, chigoba cha solder ndi ntchito zosindikizira zowonekera pamodzi ndi ntchito yosindikiza bwino. kuyesa ndi kuwongolera khalidwe. Kumvetsetsa zovuta za kupanga kwa Rogers PCB kumawunikira chisamaliro, kulondola, komanso ukadaulo womwe umakhudzidwa popanga matabwa ochita bwino kwambiri.
