M'makampani oyendetsa magalimoto, ubwino wa zida zamagetsi zimakhudza mwachindunji ntchito ndi chitetezo cha galimoto, yomwe PCB ndi imodzi mwa zigawo zikuluzikulu. Choncho, n'kofunika kwambiri kusankha odalirika magalimoto zamagetsi PCB bolodi katundu. Choncho, kodi kusankha galimoto zamagetsi PCB bolodi katundu? Lero ndikuwuzani mwatsatanetsatane kuti mutsimikizire kukhazikika kwa njira zogulitsira komanso zinthu zapamwamba kwambiri.

一

1. Kudalirika: Ma PCB amagetsi agalimoto ayenera kuthamanga kwa nthawi yayitali popanda kulephera.

2. Kukhudzidwa kwa chilengedwe: Iyenera kutengera mikhalidwe monga kutentha kwambiri ndi kutsika, kusintha kwakukulu kwa chinyezi, ndi kugwedezeka.

3. Tsatirani miyezo yamakampani: monga ISO 26262 (muyezo wapadziko lonse lapansi wamakina amagetsi okhudzana ndi chitetezo chagalimoto), IPC-A-600 ndi IPC-6012 (miyezo ya PCB yopanga ndi kuvomereza).

二、Unikani luso laopereka komanso luso lawo

1. Ziyeneretso zaukatswiri: Kaya woperekayo ali ndi ziphaso zoyenera zoyendetsera kasamalidwe kabwino, monga ISO 9001, IATF 16949 (kasamalidwe kabwino kamakampani amagalimoto).

2. Mphamvu zaukadaulo: Kufufuza ndi chitukuko cha woperekayo m'magawo apamwamba aukadaulo a PCB monga ma frequency apamwamba komanso kutumizira ma siginecha.

3. Ntchito makonda: Kaya mayankho makonda PCB angaperekedwe malinga ndi zosowa zapadera za zamagetsi zamagalimoto.

三、Unikani kukhazikika kwa chain chain komanso kuwonekera

1. Gwero la zopangira: Otsatsa abwino kwambiri adzagwiritsa ntchito zida zapamwamba kwambiri ndikupereka kuwonekera pagwero lazinthu.

2. Mphamvu yopangira: Kumvetsetsani malo opangira katundu ndi mizere yopangira kuti muwone ngati pali mphamvu zokwanira zopangira kukwaniritsa zosowa zanu.

3. Kutha kuchitapo kanthu pazochitika zadzidzidzi: Pakakhala kusokonezeka kwa katundu, kodi wogulitsa ali ndi ndondomeko yadzidzidzi kuti atsimikizire kuti kupanga sikukhudzidwa?

四、Yang'anani njira zowongolera zowongolera za omwe amapereka

1. Njira zowunikira ubwino: Ogulitsa ayenera kukhala ndi malo oyezera athunthu ndi njira, monga kuyendera ma X-ray, kuyang'ana maso (AOI), ndi zina zotero.

2. Dongosolo la Traceability: Otsatsa apamwamba kwambiri a PCB adzakhala ndi dongosolo lathunthu lazotsatira lomwe limatha kutsata mbiri yakupanga ndi kuyendera kwa PCB iliyonse.

3. Ndemanga za Makasitomala: Kumvetsetsa momwe kasitomala akuyankhira, makamaka mayankho amakasitomala okhudzana ndi magalimoto, atha kupereka chidziwitso chofunikira.

Posankha galimoto zamagetsi PCB bolodi katundu, muyenera momveka bwino kuganizira zinthu zambiri. Kupyolera mu kusanthula pamwambapa, mukhoza poyamba kuyang'ana ogulitsa omwe ali ndi luso lamakampani, luso lamphamvu, khalidwe lodalirika ndi ntchito zoganizira, poganizira kukhazikika kwa mgwirizano wautali. , tikulimbikitsidwa kukhazikitsa maubwenzi anthawi yayitali komanso okhazikika ndi ogulitsa kuti athane ndi zovuta zomwe zingachitike m'tsogolo mumakampani amagalimoto.

Zofunikira zamagalimoto zamagetsi PCB board

Ndi chitukuko chachangu chaukadaulo wamagalimoto zamagetsi, PCB ikugwiritsidwa ntchito kwambiri

mu zamagalimoto zamagetsi. Kuchokera ku makina oyendetsera injini kupita ku makina a airbag kupita ku machitidwe apamwamba othandizira kuyendetsa galimoto, khalidwe ndi machitidwe a matabwa a PCB zimakhudza mwachindunji chitetezo cha galimoto. Mfundo zokhwima ndi zofunikira ziyenera kutsatiridwa pokonza matabwa a PCB apakompyuta. Choncho, tiyeni tione. Kumvetsetsa zofunikira makonda pamagalimoto apakompyuta PCB board.

1. Kusankha zinthu

Kusankhidwa kwa zinthu zamagalimoto a PCB ndikofunikira kwambiri. Ikhoza kugwira ntchito mokhazikika pansi pazovuta zachilengedwe. Kutentha kwakukulu, kutentha kochepa, chinyezi, kugwedezeka ndi kuipitsidwa ndi zinthu zonse zomwe ziyenera kuganiziridwa. Zomwe zimagwiritsidwa ntchito kwambiri pa PCB board zikuphatikizapo FR-4, PTFE (polymer) Tetrafluoroethylene) ndi zipangizo zachitsulo, ndi zina zotero, zimatha kupereka mphamvu zokwanira zamakina ndi kukhazikika kwa kutentha.

2. Mapangidwe apangidwe

Pamene makonda makonda magalimoto kompyuta PCB matabwa, specifications kapangidwe ndi zofunika kwambiri. Nthawi zambiri amaphimba makulidwe a bolodi, kuchuluka kwa zigawo, makulidwe a zojambulazo zamkuwa, kukula ndi katayanidwe ka mapepala, m'lifupi mwake / mizere yotalikirana, etc. Kwa PCB zamagalimoto, chidwi chapadera chimafunikanso. Mapangidwe a mphamvu yake yamagetsi amatsimikizira kukhazikika ndi kugawa kofanana kwamakono.

3. Kuwongolera kutentha

Chifukwa cha kutentha kwambiri kwa chilengedwe cha magalimoto, kasamalidwe ka kutentha kwakhala chinthu chofunikira popanga matabwa a PCB apakompyuta. Kupanga koyenera kwamafuta sikungotsimikizira kugwira ntchito kokhazikika kwa zida zamagetsi, komanso kukulitsa moyo wautumiki wa mankhwalawa. Njira zoyendetsera kutentha zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo kugwiritsa ntchito zinthu zapansi panthaka zokhala ndi matenthedwe abwino, kupanga njira zoyendetsera kutentha, ndikuwonjezera ma radiator kapena mapaipi otentha.

4. Kuchita kwamagetsi

Ma board agalimoto a PCB amayenera kukhala ndi magetsi abwino kwambiri, kuphatikiza mphamvu ya dielectric yokwanira, kukana kwamphamvu kwamagetsi komanso kuthekera kotsutsana ndi ma electromagnetic interference (EMI), makamaka pamakina oteteza ndi kuwongolera magalimoto. Kulephera kwamagetsi kulikonse kungayambitse zotsatira zazikulu.

5. Kuyesedwa ndi certification

Ma board onse opangidwa mwamakonda amagetsi a PCB amafunikira kuyeserera mozama ndi kutsimikizira kuti awonetsetse kuti akugwira ntchito ndi chitetezo pamapulogalamu enieni. Mayeserowa angaphatikizepo kuyesa kwamagetsi, kuyezetsa kuyenerera kwa chilengedwe, kutsimikizira magwiridwe antchito, ndi zina zambiri, ndipo akuyeneranso kutsatira IATF 16949, ISO 9001 ndi machitidwe ena apadziko lonse lapansi.

6. Kudalirika ndi kukhazikika

Kudalirika ndi kulimba kwa matabwa agalimoto a PCB ndizizindikiro zazikulu zoyezera momwe amagwirira ntchito. Zida zapamwamba ndi njira zapamwamba ziyenera kugwiritsidwa ntchito popanga ndi kupanga mapangidwe kuti atsimikizire kuti bolodi la PCB likhoza kupitiriza kugwira ntchito pa moyo wonse wa galimotoyo, makamaka panthawi ya Pamene mukukumana ndi misewu yovuta komanso nyengo.

7. Kukonda chilengedwe

Pamene dziko likuyang'anitsitsa chitetezo cha chilengedwe, makampani opanga magalimoto akulimbikitsanso kupanga zobiriwira ndi chitukuko chokhazikika. Kupanga ma board amagetsi a PCB agalimoto kuyeneranso kuganizira za chilengedwe, monga kugwiritsa ntchito solder wopanda lead ndi zida zomwe zimagwirizana ndi miyezo yachilengedwe monga RoHS ndi REACH.

Kusintha makonda a matabwa amagetsi a PCB ndi njira yovuta komanso yokhwima yomwe imaphatikizapo mbali zambiri zaukadaulo ndi miyezo, kuyambira pakusankha zinthu mpaka kupanga, kuyambira pakuwongolera matenthedwe mpaka magwiridwe antchito amagetsi, mpaka kuyesa satifiketi ndi kuyanjana kwa chilengedwe, ulalo uliwonse uyenera kukhala wowongolera bwino kuti utsimikizire chinthu chomaliza. ntchito ndi chitetezo. Ndi kupita patsogolo kwaukadaulo komanso kufunikira kwa msika, miyeso ndi zofunikira pakusintha makonda agalimoto a PCB zipitilira kusinthika kuti zigwirizane ndi zosintha zamtsogolo zamagalimoto.
