Ta yaya aka ƙirƙira Rogers PCb?

Rogers PCB, wanda kuma aka sani da Rogers Printed Circuit Board, ya shahara sosai kuma ana amfani dashi a masana'antu daban-daban saboda ingantaccen aiki da amincinsa. An kera waɗannan PCB daga wani abu na musamman da ake kira Rogers laminate, wanda ke da kayan lantarki na musamman da na injina. A cikin wannan blog post, za mu nutse cikin intricacies na Rogers PCB masana'antu, binciko da matakai, kayan, da kuma la'akari da hannu.

Don gane da Rogers PCB masana'antu tsari, dole ne mu farko fahimtar abin da wadannan allon ne da kuma gane abin da Rogers laminates nufi.PCBs sune mahimman sassa na na'urorin lantarki, suna ba da tsarin tallafi na inji da haɗin lantarki. Rogers PCBs ana nema sosai a aikace-aikacen da ke buƙatar watsa siginar mita mai girma, ƙarancin asara da kwanciyar hankali. Ana amfani da su sosai a masana'antu kamar sadarwa, sararin samaniya, likitanci da motoci.

Kamfanin Rogers, sanannen mai samar da mafita na kayan, ya ɓullo da laminates na Rogers musamman don amfani da shi wajen kera kwamitocin da'ira mai inganci. Rogers laminate wani abu ne mai haɗaka wanda ya ƙunshi zanen fiberglass ɗin da aka saka da yumbu mai cike da yumbu tare da tsarin resin thermoset na hydrocarbon. Wannan cakuda yana nuna kyawawan kaddarorin lantarki kamar ƙananan asarar dielectric, haɓakar zafin jiki mai girma da ingantaccen yanayin girma.

Yanzu, bari mu shiga cikin Rogers PCB masana'antu tsari:

1. Tsare-tsare:

Mataki na farko na yin kowane PCB, gami da PCBs Rogers, ya ƙunshi zayyana shimfidar da'ira. Injiniyoyin suna amfani da software na musamman don ƙirƙirar ƙirƙira na allon kewayawa, sanyawa da haɗa abubuwan da suka dace daidai. Wannan matakin ƙira na farko yana da mahimmanci wajen ƙayyade aiki, aiki, da amincin samfurin ƙarshe.

2. Zaɓin kayan aiki:

Da zarar zane ya cika, zaɓin kayan ya zama mahimmanci. Rogers PCB yana buƙatar zaɓar kayan laminate da ya dace, la'akari da abubuwan da ake buƙata kamar dielectric akai-akai, rarrabuwa factor, thermal conductivity, da inji Properties. Rogers laminates suna samuwa a cikin nau'i-nau'i iri-iri don saduwa da bukatun aikace-aikace daban-daban.

3. Yanke laminate:

Tare da zane da zaɓin kayan aiki cikakke, mataki na gaba shine yanke laminate na Rogers zuwa girman. Ana iya samun wannan ta amfani da kayan aikin yankan na musamman kamar na'urorin CNC, tabbatar da ma'auni daidai da guje wa duk wani lalacewa ga kayan.

4. Hakowa da tagulla:

A wannan mataki, ana zubar da ramuka a cikin laminate bisa ga tsarin kewaye. Waɗannan ramukan, da ake kira vias, suna ba da haɗin lantarki tsakanin nau'ikan PCB daban-daban. Ramukan da aka haƙa ana yi musu plate ɗin tagulla don tabbatar da aiki da kuma inganta ingantaccen tsarin ta hanyar.

5. Hoto na kewaye:

Bayan hakowa, ana amfani da Layer na jan karfe akan laminate don ƙirƙirar hanyoyin da ake buƙata don ayyukan PCB. An lulluɓe allon tagulla tare da wani abu mai haske wanda ake kira photoresist. Sa'an nan kuma ana canja wurin ƙirar da'ira zuwa photoresist ta amfani da fasaha na musamman kamar photolithography ko hoto kai tsaye.

6. Fitowa:

Bayan da aka buga zanen kewayawa a kan photoresist, ana amfani da sinadarai don cire jan karfe da suka wuce. Ecchant yana narkar da tagulla maras so, yana barin bayan tsarin da'irar da ake so. Wannan tsari yana da mahimmanci don ƙirƙirar alamun da ake buƙata don haɗin wutar lantarki na PCB.

7. Layer alignment da lamination:

Don PCBs Rogers Multi-Layer, kowanne yadudduka sun daidaita daidai ta amfani da kayan aiki na musamman. Waɗannan yadudduka an jera su kuma an lika su tare don samar da tsarin haɗin gwiwa. Ana amfani da zafi da matsa lamba a jiki da na lantarki sun haɗa yadudduka, tabbatar da aiki a tsakanin su.

8. Electroplating da surface jiyya:

Don kare kewayawa da kuma tabbatar da dogaro na dogon lokaci, PCB yana jurewa tsarin jiyya da jiyya. Ƙarfe mai bakin ciki (yawanci zinari ko gwangwani) ana lulluɓe shi akan wani fili na tagulla. Wannan shafi yana hana lalata kuma yana samar da wuri mai dacewa don abubuwan da aka gyara.

9. Solder mask da aikace-aikacen allo na siliki:

Ana lulluɓe saman PCB tare da abin rufe fuska mai siyarwa (yawanci kore), yana barin wuraren da ake buƙata kawai don haɗin abubuwan. Wannan Layer na kariya yana kare alamun tagulla daga abubuwan muhalli kamar danshi, ƙura, da hulɗar haɗari. Bugu da ƙari, ana iya ƙara yadudduka na siliki don yin alamar shimfidar wuri, masu ƙira da sauran bayanan da suka dace akan saman PCB.

10. Gwaji da Kula da inganci:

Da zarar tsarin masana'anta ya cika, ana gudanar da cikakken gwaji da shirin dubawa don tabbatar da PCB yana aiki kuma ya dace da ƙayyadaddun ƙira. Gwaje-gwaje daban-daban kamar gwajin ci gaba, gwajin ƙarfin lantarki mai ƙarfi da gwajin rashin ƙarfi suna tabbatar da mutunci da aikin PCBs na Rogers.
