PCB anabala gulu gulu

Malinga ndi kuchuluka kwa zigawo, bolodi ladela lidagawika ma PCB osanjikiza, ma PCB awiri, ndi bolodi lazambiri zingapo magulu atatu akuluakulu.

Yoyamba ndi bolodi loyang'anira limodzi. Pa PCB yoyambira kwambiri, zinthuzi zimayikidwa mbali imodzi ndi mawaya ena ku mbali ina ya mtunduwu imatchedwa bolodi yoyenda limodzi chifukwa mawaya amangowonekera mbali imodzi. mtengo wake, koma choyipa ndikuti sangathe kugwiritsidwa ntchito pazinthu zovuta kwambiri.

Bokosi lazigawo ziwiri ndikulumikiza kwa bolodi limodzi lokhalokha. Mbali ziwiri zokha zimakhala ndi zokutira zamkuwa ndi zingwe, ndipo kulumikizana pakati pa magawo awiriwo kumatha kutsogozedwa kudzera mu dzenje kuti apange kulumikizana kofunikira kwa netiweki.

Multilayer board board imatanthawuza bolodi losindikizidwa lomwe lili ndimitundu itatu kapena kupitilira apo yazithunzi zosiyanitsidwa ndi zida zotsekera momwemo, ndipo mawonekedwe ake amalumikizidwa monga amafunira.Multilayer board board ndizomwe zimapangidwa ndi ukadaulo wazidziwitso zamagetsi kupita kumalo othamanga kwambiri, Mipikisano ntchito, lalikulu mphamvu, buku laling'ono, woonda ndi opepuka.

Malinga ndi mawonekedwe a board board agawika ), board yolimba ( PCB ), bolodi lofewa komanso lolimba ( FPCB ).

Momwe mungasiyanitsire masanjidwe osanjikiza amitundu ingapo kuchokera bolodi limodzi lokhazikika

1. Tengani kuwala. Phata lamkati ndilopepuka, ndiye kuti, zonse zakuda, ndiye kuti bolodi yama multilayer; Mosiyana, gulu limodzi komanso kawiri, pomwe gulu limodzi lili ndi gawo limodzi lokha ndipo mulibe mkuwa mu dzenje. Gulu lowongolera ndi mizere yakutsogolo ndi kumbuyo, kuwongolera dzenje ndi mkuwa.

2. Kusiyana kwakukulu kwambiri ndi kuchuluka kwa mizere:

Dongosolo limodzi lokhazikika limakhala ndi dera limodzi lokha (wosanjikiza mkuwa), mabowo onse ndi mabowo osakhala achitsulo, palibe njira yamagetsi

Bokosi loyenda kawiri limakhala ndi magawo awiri oyendetsa (mkuwa wosanjikiza), dzenje lazitsulo ndi dzenje losakanikirana, makina osinthira magetsi

3. Bungwe loyendetsa dera limagawika gawo limodzi lokhalokha, bolodi yazigawo ziwiri komanso bolodi lazoyenda zingapo. Makina osanjikiza angapo amatanthauza bolodi la dera lomwe lili ndi zigawo zitatu kapena kupitilira apo. Njira yopangira ma board angapo osanjikiza idzakhazikitsidwa pagulu limodzi komanso kawiri kuphatikiza makina osindikizira amkati. Kugwiritsa ntchito zosokoneza kungathenso kusanthula.

Ndi zinthu ziti zomwe zimafunikira bolodi la PCB

Zida zamagetsi zomwe zimafuna ma circuits ophatikizika ziyenera kusinthidwa kukhala ma board board osindikizira kuti zisunge malo, zimapangitsa kuti zinthuzo zikhale zopepuka / zolimba / ndikukwaniritsa magwiridwe antchito abwino.

Sizida zamagetsi zilizonse zomwe zimafunikira bolodi loyenda, zida zamagetsi zosavuta kuchita popanda dera ngati mota wamagetsi Koma zida zamagetsi zomwe zimakhala ndi ntchito zina zimafunikira ma board a dera kuti azigwiritsidwa ntchito monga mawayilesi, mawailesi, makompyuta, ndi zina zambiri. Wophika mpunga amakhalanso ndi PCB pansi, kazembe wa zimakupiza,

Kodi mtundu wa mankhwala ntchito PCB bolodi

Bokosi lolimba la PCB nthawi zambiri limatanthawuza, mu boardboard yama kompyuta, mbewa, zojambula, zida zakuofesi, osindikiza, ma fotokopeza, oyang'anira kutali, mitundu yonse yamajaja, makina ojambulira, kamera ya digito, wailesi, bolodi la TV, cholumikizira chingwe, foni yam'manja, kutsuka makina, sikelo yamagetsi, foni, nyali za LED ndi nyali, zida zamagetsi zamagetsi: ma air conditioner, mafiriji, ma audio, MP3, zida zamagetsi, GPS, galimoto, zida zamankhwala, ndege, zida zankhondo, mivi, ma satelayiti, ndi zina zambiri (ndi APCB imachitanso chimodzimodzi. Ndi bolodi loyendetsa dera, koma lofewa, ngati chivundikiro cholumikizira foni yolumikizana ndi kiyi pakati pa dera limagwiritsidwa ntchito pa bolodi la dera).

Ma boardboard am'manja, dinani bolodi, ndi bolodi lolimba; Mafoni otseguka kapena ma clamshell amalumikizidwa ndi mzere ndi mbale yofewa. Maulamuliro akutali nthawi zambiri AMAGWIRITSA ntchito kanema wa kaboni. Bokosi lam'manja kuchokera kumtunda ndi rf dera, magetsi, dera lamawu, dera logic

Nthawi zambiri kumangotenthetsera ketulo popanda bolodi lantchito, bulaketi yolumikizira molumikizana.Opereka madzi amakhala ndi matabwa oyenda.Ophika mpunga nthawi zambiri amakhala ndi mabodi azizungulira. wa kayendedwe ka liwiro, nthawi, kuwonetsa ndi zina zotero, ndipo magwiridwe antchito a magetsi samatha kugwira ntchito.

Ndi zinthu ziti zomwe zimagwiritsa ntchito magawo awiri ndipo ndi zinthu ziti zomwe zimagwiritsa ntchito magawo angapo

Zimatengera ngati magwiridwe antchito apawiri awiri angakwaniritsidwe, monga mphamvu yotsutsana ndi zosokoneza, zingwe, zingwe za EMC ndi magwiridwe antchito awiri omwe angakwaniritsidwe, palibe chifukwa chogwiritsa ntchito bolodi lamitundu ingapo.

Zomwe zili bwino, bolodi lama multilayer kapena bolodi limodzi lokhazikika

Gulu la Multilayer ndiye mtundu wama board omwe amagwiritsidwa ntchito kwambiri pamoyo watsiku ndi tsiku. Kodi maubwino ogwiritsa ntchito amtundu wosanjikiza wa PCB ndi uti?

Ntchito ntchito bolodi Mipikisano wosanjikiza PCB:

1. Kuchulukana kwamisonkhano yayikulu, voliyumu yaying'ono ndi kulemera kopepuka zimakwaniritsa zofunikira zowunikira ndi kugwiritsa ntchito zida zamagetsi zamagetsi;

2. Chifukwa cha kuchuluka kwa msonkhano waukulu, kulumikizana pakati pa chinthu chilichonse (kuphatikiza zinthu) kumachepa, ndikuyika kosavuta komanso kudalirika kwambiri;

3. Chifukwa cha kubwereza komanso kusasinthasintha kwa zojambulazo, zolakwika za waya ndi msonkhano zimachepetsedwa ndipo nthawi yokonza, kukonza zolakwika ndi kuyang'anira zida zasungidwa;

4. Chiwerengero cha zigawo zamawaya chitha kukulitsidwa, motero kukulitsa kusinthasintha kwamapangidwe;

5, imatha kupanga dera linalake la impedance, imatha kupanga makina othamangitsa othamanga kwambiri;

6. Makina osanjikiza oyendetsera dera ndi maginito amatha kukhazikitsidwa, ndipo chitsulo chosungunuka chachitsulo chimatha kukhazikitsidwanso kuti chikwaniritse zosowa zapadera monga kutchinga ndi kutaya kwanyengo.

Ndikukula kopitilira kwa ukadaulo wamagetsi ndi makompyuta, zamankhwala, zoyendetsa ndege ndi mafakitale ena pakusintha kosalekeza kwa zida zamagetsi, ma board a dera akucheperachepera, ndikucheperachepera komanso kukulirakulira chifukwa chakuchepa kwa malo, ndi kosatheka kupititsa patsogolo kuchuluka kwa msonkhano wamitengo yosindikizidwa imodzi ndi iwiri. Chifukwa chake, ndikofunikira kulingalira pogwiritsa ntchito ma bolodi oyenda masanjidwe angapo okhala ndi zigawo zochulukirapo komanso kuchuluka kwa msonkhano.M bolodi oyendetsa masanjidwe angapo okhala ndi kapangidwe kake kosasintha, magwiridwe antchito ndi odalirika pamagetsi komanso magwiridwe antchito azachuma, agwiritsidwa ntchito kwambiri pakupanga zamagetsi mankhwala.

Zomwe zili pamwambazi ndi: bolodi yamagawo angapo komanso bolodi limodzi lokhazikika momwe mungasiyanitsire mawu oyamba, ndikhulupilira mungakonde! Kuti mupeze mafunso ambiri okhudza bolodi la dera, chonde lemberani China wopanga pcb- Yongmingsheng dera board Factory ~
