Sezvo masekete akaomesesa anoda mamwe matanho ekugadzira uye kushandisa zvimwe zvikamu izvo zvinogona kukonzera kudhura kwekutenga, pamwe nemutengo wekupedzisira wegungano. Iyo yakaoma yedunhu dhizaini inovhara yakawanda PCB bhodhi nzvimbo yekubatanidza zvimwe zvikamu pamabhodhi uye inoteedzera uye ichawedzera mutengo.
PCB Kutungamira Nguva uye Kuendesa
- Kana chero vashandisi vanoda nekukurumidza bhodhi kutumirwa munguva pfupi, vagadziri vePCB vanoshanda nguva yakawandisa uye vanowana masevhisi ekuwedzera mashifiti kubva kuvashandi ayo anochaja yakawanda kune vatengi kuendesa zvinodiwa panguva yakapihwa. Saka zvakazara, mutengo wevashandi uye kushandiswa kwezviridzwa zvekugadzira zvinoita kuti PCB yekupedzisira kugadzira inodhura.
- Kuzadzisa zvinodiwa nevatengi nekukurumidza, nzira dzakakosha dzekutakura dzinoshandiswa pakutumira pamhepo, senge kuburitsa masevhisi. Izvi zvakakosha zvinhu zvinowedzera mitengo, wedzera mamwe machaji ekufambisa uye kuwedzera mutengo webhodhi.
- Iyo ipfupi yekutumira nguva inokanganisa zvakare vagadziri 'masheji ekugadzira uye maitirwo enguva yakapihwa yekupedzisa odha. Iyo inouyawo nekugadzirisazve mitsetse yekugadzira kana kukurumidza kushanda, izvo zvinokanganisawo mutengo.
Copper Kukora
- Mutengo wePCB board unobvawo pafoiri yemhangura, inova chikamu chikuru chebhodhi; kukosha kwayo kunobva pakukora. Yakakora yemhangura foil inoshandisa yakakura mhangura, uye semhedzisiro, mari yezvinhu zvebhodhi inowedzera.
- Pakugadzirisa mhangura yakakora, matanho ekugadzirisa akawanda anobatanidzwa, uye zvimwe zviridzwa zvinoshandiswa kugadzira mabhodhi emhando. Mabheti akasimba akadaro anoshandiswa kuchera kwakaringana uye etching anotorawo nguva. Saka zvinhu zvese izvi zvinoita kuti mapuranga adhure.
PCB Huwandu uye Kurongeka Zvinhu
- Chimwe chinhu chikuru chinogona kukanganisa mutengo wePCB huwandu hwemapuranga. Kana iwe uri kuraira nhamba yakakura yemabhodhi, izvo zvinowedzerawo mutengo wako sezvo zvichatora nguva yakawanda kupedzisa uye zvimwe zvinhu zvichashandiswa, izvo zvinoita kuti idhure.
- Nekudaro, vamwe vagadziri vane zvimwe zvidzikiso zvemaodha akawanda ePCB anogona kubatsira kudzikisa mutengo wako kune yakakura nhamba yePCB. Sezvo mutengo wekushandisa, machaji ekuseta, uye madhizaini edhizaini akaiswa kune yakakura nhamba yemayunitsi panguva imwe chete, izvo zvinobatsira kudzikisa mutengo weakawanda maodha.
- Kune mumwe PCB mutengesi ane diki yekurongeka muganhu iyo inowedzerawo mutengo weodha yakaderera sezvo diki yuniti mitengo ichikwira saka maodha akawanda anogona kudhura mune zvehupfumi zvichienderana neashoma masevhisi kana vagadziri. Unogona kusarudza Zvinoshamisa PCB kuti uwane PCB board yako nemhando yakanaka.
Nzvimbo uye Supplier Factors
- Nzvimbo yemutengesi wako wePCB inokanganisawo mutengo wako wekugadzira bhodhi kubva pakuwana masevhisi ekugadzira PCB kubva kune vatengesi vari munzvimbo dziri pedyo newe kunoderedza mutengo wekutumira uye zvakare kuderedza nguva yekutumira. Asi kana ukasarudza mumwe mutengesi wedunhu, izvo zvinoita kuti bhodhi rako ridhure, uye pamwe hauzowana odha panguva yakapihwa.
Zvimwe zvinhu zvinodhura zvePCBs
Prototype uye Mutengo Wekuyedza:
- Asati agadzira yekupedzisira PCB bhodhi, prototype inogadzirwa, uye bvunzo dzakasiyana dzinoitwa kuzadzisa zvinodiwa zvemagadzirirwo maficha uye kudiwa. Iyi nzira inotora nguva uye inoshandisa mamwe masosi anokanganisa yekupedzisira bhodhi gungano mutengo.
Gungano uye Kuongorora Mari
- Mushure mekupedzwa kwemaitiro ekugadzira, kune bvunzo dzakasiyana dzinoitirwa gungano kuti itarise kushanda kwayo. Iyo inotora nguva uye inoshandisa michina yakasiyana inoita kuti maitiro adhure, uye PCB gungano remari rinowedzera.
Quality Control Cost
- Kuti uzadzise zviyero zvePCB, kune kumwe kuyedzwa uye chitupa kunodiwa, sekuyedzwa kwemagetsi, kuongororwa kwezvakatipoteredza, uye chitupa chekuchengetedza. Aya ekuwedzera maitiro anokanganisawo mitengo yebhodhi kana vachida zvitupa zvakasiyana.
Maitiro ekuverengera Tsika PCB Mutengo nehukuru
Kuti uwane mutengo weiyo PCB board, shandisa nzira dzakareruka dziri nharaunda-inoenderana nemitengo yekuverenga nzira dzinowanzo shandirwa kune zvidiki zvigadzirwa pamwe neprototypes.
Nenzira iyi, vagadziri vePCB vanopa mazano emutengo zvichienderana nehukuru hwemapuranga, iri nzira iri nyore yekuwana mutengo webhodhi.
- Matekiniki emitengo anoenderana nenharaunda anobatsira vanogadzira mabhodhi ePCB kuverenga mutengo weyuniti pa square centimita zvichienderana nehuwandu hwematanho uye maitiro ekugadzira anoshandiswa pabhodhi.
- Mukuita uku, vagadziri vanoda zviyero zvakaringana kubva kune vatengi uye mari yekupedzisira ichawanikwa kuburikidza nechigadzirwa chenzvimbo yebhodhi ine mutengo watotsanangurwa wemayuniti.
- Ngatitii vagadziri vakaisa mutengo wezvikamu zviviri zvebhodhi pamadhora 2 paskweya centimita, uye hukuru hwebhodhi rako hunoita 0.05 cm x 15 cm.
- PCB bhodhi nzvimbo ichava 15 cm x 20 cm = 300 sq. cm.
- Mutengo webhodhi retsika uchava = 300 sq. cm x 0.05sq.cm = $15.
Nzira yekudzikisa sei PCB Manufacturing Costs?
Zvikamu zvakasiyana zvinofanirwa kuteverwa pakudzikisa mutengo wegungano rese.
Dunhu Dhizaini
- Kana dhizaini yako yedunhu iri nyore uye isina matambudziko mazhinji, inogona kubatsira kudzikisa iyo yakazara bhodhi mutengo. Iyo yakapfava dhizaini inoshandisa mashoma ezvikamu, uye inokanganisa kudzikiswa kwekutenga uye kubhadharisa gungano. Iyo yakapfava dhizaini zvakare inoshandisa yakaderera nhamba yezvikamu uye inoderedza maitiro pamwe chete nemari yezvinhu zvebhodhi.
Layer Numbers:
- Pamusoro, takakurukura nezvehuwandu hwezvikamu zvebhodhi zvine mhedzisiro huru pamutengo. Kana iwe ukashandisa mashoma akaturikidzana emapuranga, zvinoderedza mutengo wezvinhu, kuderedza mari yako yekuita, uye pakupedzisira kudzikisa mitengo yebhodhi.
Zvikamu zvakajairwa
- Nokuda kwekushandiswa kwebhodhi, kushandiswa kwezvikamu zvakajairika kunobatawo mitengo yebhodhi. Sezvo zviyero zvakajairwa zviri nyore kuwana uye zvakare zvine mutengo wakaderera pane zvakakosha zvikamu. Iko kushandiswa kwezvikamu zvakajairika kunoita kuti dhizaini ive nyore uye inoderedza huwandu hwematanho ebhodhi uye yekupedzisira chigadzirwa mutengo.
Yakagadziridzwa PCB Saizi
- Isu tinogona zvakare kudzikisa mutengo wePCB nekuita zvimwe optimizations muhukuru hwebhodhi uye chimiro. Bhodhi duku rinoshandisa zvinhu zvakaderera uye rinoda zvishoma maitiro ekudzora mari yekugadzira. NePCB iyoyo ine chimiro chakareruka, matanho mashoma uye zviridzwa zvinodiwa pakugadzira bhodhi uye kuderedza mitengo.
Manufacturability (DFM) zvikumbiro
- Kana tikashandisa misimboti yeDFM, inozobatsirawo kubata magadzirirwo ebhodhi nenzira kwayo uye kuita kuti kugadzira kwedu kwekupedzisira kudhure. DFM yePCB dhizaini haingodzikisi mutengo wekugadzira chete asiwo inowedzera mhando uye inoita mabhodhi akavimbika. Zvakadai sekushandiswa kwezvimiro zveDFM, tinoshandisa upamhi hwakakodzera hwemitsara uye spacings kubatsira kushandisa maburi ekuboora akati wandei, uye pakupedzisira, tinowana mabhodhi anodhura.
mhedziso
Iko kuverengerwa kwemitengo yemabhodhi ePCB kunobva pazvinhu zvakasiyana senge maficha ebhodhi, mhando dzezvinhu, maitiro ekugadzira, uye mavhoriyamu ekugadzira. Kukosha kwezvinhu zvese izvi uye ruzivo rwavo rwakafanira runotibatsira kugadzira yakanaka inoshanda uye yemhando yepamusoro bhodhi ine bhajeti-inoshamwaridzika yekupedzisira PCB chirongwa. Pane nzira dzakasiyana dzinoshandiswa pakuverenga mitengo yePCB, senge nharaunda-yakavakirwa mutengo kuverengera kune prototypes, yakadzama yekutemerwa mutengo weakawanda mavhoriyamu, uye kushandiswa kwemamwe maturusi, asi chimwe nechimwe chine zvachinoda.
Pakupedzisira, kusarudza yakanakisa uye yakavimbika PCB mugadziri kwakakosha kwazvo mune yakakwira-voltage PCB dhizaini uye kusangana. Kusarudzwa kwevatengesi vechokwadi vane ruzivo rwakakwana rwekuverenga kwePCB mutengo unobatsira kugadzira mabhodhi emhando nemutengo wakanaka. Kana iwe uchitsvaga vane musoro uye vanodhura-vanogadzira PCB vagadziri, saka WoderFulPCB ndiyo yakanyanya kunaka sarudzo kwauri. Ndiko kutungamira vagadziri vePCB uye kupa emhando yepamusoro PCB prototyping, kugadzira, uye masevhisi egungano nemitengo yakanaka. Ngozi yetsaona uye kuuraya kwakawedzera mumasisitimu ane hutsika husina kunaka uye kusakwana kufunga kwepamusoro-voltage PCBs. Vagadziri vePCB vanofanirwa kunyatso funga nezve creepage uye kureba madaro kuti vaderedze arcing uye kuchengetedza kwakaringana magetsi ega anodiwa.
