Kiyi yekugadzira maitiro ekudzora epamusoro nhanho PCB

1. Nhanganyaya kududziro yezita
Rakadhindwa redunhu – pamusoro pechinhu chinodzivirira, inopa maitiro ekutenderera emagetsi kubatana pakati pezvinhu, kusanganisira zvinodzivirira zvinhu.
Rakadhindwa redunhu – dunhu rakagadzirwa nedunhu rakadhindwa, rakadhindwa chinhu, kana mubatanidzwa wezviviri, zvinoenderana nedanho rakagadzirirwa pamusoro pechinhu chekudzivirira zvinhu.
Rakadhindwa redunhu / redunhu bhodhi – izwi rakajairika rekudzivirira mabhodhi ayo apedzwa neakadhindwa wedunhu kana akadhindwa wedunhu. Mellors | | ai | | | P CB sampuro mitsetse, 1, 1, ai, 1 kupatsanura 1 hunyanzvi hwekutanga P | 1 CB muyenzaniso pepa
Yakadzika density PCB – Misa inogadzirwa PCB ine tambo yakakura kupfuura 0.3 mm (12 / 12mil) muhupamhi pakati pemadhisiki maviri panosangana iyo 2.54 mm standard grid.
Pakati wepakati pcbbc – Bhodhi-rakagadzirwa rakadhindwa bhodhi ine waya mbiri dzinenge 0.2 mm (8 / 8mil) muhupamhi pakati pemadhisiki maviri panosangana iyo 2.54 mm standard grid.
Yakakwira density Yakadhindwa Bhodhi – Bhodhi-rakaburitswa rakadhindwa bhodhi ine waya nhatu pakati pemadhisiki maviri pamharadzano ye2.54 mm yakajairwa grid upamhi hwe0.1 kusvika 0.15 mm (4-6 / 4-6mil).
2. Ndedzipi mhando dzemaseketi akadhindwa zvinoenderana neiyo substrate uye conductive pateni inoshandiswa? Mellors | | ai | | | Pcb sampuro mitsetse, 1, 1, ai, 1 kupatsanura 1 hunyanzvi hwekutanga P | 1 CB muyenzaniso pepa
– Zvinoenderana ne substrate yakashandiswa: kuomarara, kusanduka, kuomarara-kusanduka;
– Zvinoenderana nema conductive girafu: isina, yakapetwa, yakawanda-yakaturikidzana.
3. Tsanangura kushanda kwedunhu rakadhindwa uye hunhu hweindasitiri yedunhu yakadhindwa.
– Chekutanga pane zvese, inopa mehendi rutsigiro rwePCB kopi bhodhi kugadzirisa uye kuungana kwevatambi, maseketi akabatanidzwa, resistors, capacitors, inductors uye zvimwe zvikamu.
Chechipiri, inoziva iyo wiring uye kubatana kwemagetsi pakati pezvinhu zvakaita se transistors, maseketi akasanganiswa, resistors, capacitors uye inductors, uye kuputira kwemagetsi kusangana neayo magetsi maitiro.
Chekupedzisira, mavara ekuzivikanwa uye magiraidhi anopihwa kuongororwa uye kugadziriswa kwezvinhu zviri muPCB yemagetsi gungano maitiro, uye ichivharira kutenderera magiraidhi anopihwa kune wave soldering.
– Tekinoroji yepamusoro, mari yakakwira, njodzi huru uye purofiti yakakura. Mellors | | ai | | | P CB sampuro mitsetse, 1, 1, ai, 1 kupatsanura 1 hunyanzvi hwekutanga P | 1 CB muyenzaniso pepa
4. Yakadhindwa yedunhu yekugadzira maitiro kupatsanura inowanzo kuve yakakamurwa kuita ipi nzira mbiri? Ndezvipi zvakanakira chimwe nechimwe?
– Yekuwedzera nzira: dzivisa yakawanda nhamba yendarira etching, kuderedza mutengo. Yakareruka pcb kopi bhodhi yekugadzira maitiro, inatsiridza kugadzirwa kwemhando. Mafaya waya uye nzvimbo dzinoyerera dzinogona kuwanikwa. Kuvimbika kwegomba resimbi kunovandudzwa.
– Yekuderedza nzira: yakakura, yakagadzikana uye yakavimbika maitiro. Mellors | | ai | | | P CB sampuro mitsetse, 1, 1, ai, 1 kupatsanura 1 hunyanzvi hwekutanga P | 1 CB muyenzaniso pepa
5. Ndeapi marudzi ekuwedzera maitiro anoshandiswa mukudhinda wedunhu kugadzira? Nyora maitiro acho zvakasiyana?
– Yese nzira yekuwedzera: kuchera, imaging, viscosifying kurapwa (isina chikamu), isina magetsi emhangura yakanamirwa pamadziro, kubviswa kwekudzivisa.
– Hafu yekuwedzera nzira: kuchera, kurapa kwekusimudzira uye tackification, electroless mhangura yakanamirwa pamifananidzo, imaging (electroplating resist), graphic electroplating mhangura (negative phase), kubvisa kuramba, kusiyanisa etching.
– Yakasarudzika yekuwedzera nzira: imaging (anti-etching), etching mhangura (yakajairwa chikamu), kubvisa resist layer, yakazara ndiro yekumhara electroplating kuramba, kuchera, isina magetsi mhangura yakadzika mugomba, kubvisa electroplating kuramba.
6. Ndedzipi mhando dzedunhu rakadhindwa muchirongwa chekubvisa? Nyora mafambiro kuyerera kwese ndiro yakakwenenzverwa uye graphic yakanamirwa pamifananidzo. Mellors | | ai | | | P CB sampuro mitsetse, 1, 1, ai, 1 kupatsanura 1 hunyanzvi hwekutanga P | 1 CB muyenzaniso pepa
– Yisiri-yakapetwa yakavezwa pcb, yakapetwa pcb pcb, yakapetwa yakavharwa pcb uye yepamusoro yakatasva pcb.
– Yese ndiro electroplating (masking nzira): kuvhara, kuchera, metallization yemaburi, kuomesa kweplate yakazara electroplating, kurapwa kwepamusoro, kunamatira kwechiedza masking mhando yakaoma firimu, kugadzira yakajairwa waya mifananidzo, etching, firimu kubvisa, plug electroplating, chimiro kugadzirisa, kuongorora, kudhinda kweinodzivirira kuramba kupfeka, kupisa kwemhepo unopisa, kudhinda kweneti yezviratidzo zvekumaka, zvigadzirwa zvakapera.

–PCB graphic electroplating (isina mhangura inodzivirira kupikisa firimu): Akapetwa maviri emhangura-akapfeka mabhodhi anovhara, kubaya gomba, CNC kuchera, kuongorora, kuita mutsipa, mutete mutete wemagetsi isina mhangura, electroplating mhangura, kuongorora, brashe ndiro, chinamirwa (kana kudhinda screen. ), kufungidzira kwekuratidzira (kana kurapa), kuongorora retouching, electroplating mhangura, magiraidhi ari electroplating tin lead alloy, enda kune iyo firimu (kana bvisa) yakadhindwa, kuongorora retouching, etching, pewter kumashure, yakavhurika wedunhu bvunzo, yakachena, kuramba welding mifananidzo , plug nickel yakanamirwa pamifananidzo / goridhe, plug yekunamatira tepi, inopisa mweya kuenzanisa, kuchenesa, network kudhinda zviratidzo, chimiro kugadzirisa, kuchenesa uye kuomesa, kuongorora, kurongedza, zvigadzirwa zvakapedzwa.
7. Electroplating tekinoroji inogona kukamurwa mumhando dzipi dzetekinoroji?
– Kwakajairika porous yakanamirwa pamifananidzo rwokugadzira, yakananga yakanamirwa pamifananidzo zvemichina, conductive namira michina. Mellors | | ai | | | P CB sampuro mitsetse, 1, 1, ai, 1 kupatsanura 1 hunyanzvi hwekutanga P | 1 CB muyenzaniso pepa
8. Ndeapi makuru maficha emabhodhi anodhindwa? Chii chine hwaro hwayo zvinhu zvine?
– Inochinjika uye inopetwa kudzikisa vhoriyamu; Kurema kwechiedza, yakanaka wiring kuenderana, kuvimbika kwakakwirira.
9. Tsanangura maficha akakosha uye mashandisiro ePSG yakaoma – inochinjika.
– Izvo zvikamu zvakaomarara uye zvinopfava zvakabatanidzwa, kubvisa kudikanwa kwekubatanidza, kubatana kwakatendeka, kudzikisira uremu, musangano miniaturization. Pcb kukopa bhodhi kunonyanya kushandiswa mune zvekurapa zvemagetsi zviridzwa, makomputa uye zvigadzirwa, zvekutaurirana michina, muchadenga michina michina uye nyika dziviriro nemauto zvishandiso.

10. Tsanangura hunhu hwe conductive inonamira yakadhindwa bhodhi.
– Rakareruka gadziriso tekinoroji, yakakwira kugadzirwa kushanda, yakachipa mutengo, shoma mvura yemarara.
11. Chii chinonzi wiring pcb yakawanda?

– Rakadhindwa bhodhi rakagadzirwa nekugadzika waya dzesimbi yakananga pane insulating substrate.
12. Chii chinonzi simbi – yakavakirwa rakadhindwa bhodhi? Ndezvipi zvinhu zvikuru?
– General izwi resimbi base yakadhindwa bhodhi uye simbi musimboti yakadhindwa bhodhi. Mellors | | ai | | | P CB sampuro mitsetse, 1, 1, ai, 1 kupatsanura 1 hunyanzvi hwekutanga P | 1 CB muyenzaniso pepa
13. Chii chinonzi single-mativi multilayer pcb? Ndezvipi zvinhu zvikuru?
Kugadzira kwemazhinji multilayer wedunhu mabhodhi pane imwechete pcb. Pcbboard bhodhi hunhu: kwete chete inogona kudzora yemukati yemagetsi wave kune iyo yekunze radiation, asi zvakare inogona kudzivirira kupindirwa kwekunze kwemagetsi wave kwairi, hakudi gomba metallization, yakaderera mutengo, kurema uremu, inogona kuve yakatetepa.
14. Sumo ipfupi kududziro uye kugadzirwa kwemazhinji multilayer akadhindwa wedunhu?
– Iyo yakakwira dhivhaiti yakawanda-yakatenderera wiring yakadhindwa bhodhi inoitwa nekuchinjisa insulating dura uye conductive rara munzira yekukochekera dura pane yemukati nhete yeiyo yakapedziswa yakawanda-yakatenderera bhodhi, uye mabofu mapofu anoshandiswa zvakasununguka kuitisa pakati pezvikamu.
