Layout ke e 'ngoe ea lintlha tse ka sehloohong tsa moralo oa PCBA ho netefatsa botšepehi ba matšoao le tsamaiso ea mocheso ea boto.Mona ke tse ling tsa mekhoa e metle ka ho fetisisa moralong oa PCBA ho netefatsa botšepehi ba matšoao le taolo ea mocheso:
Pontšo ea Botšepehi Mekhoa e Molemo ka ho Fetisisa
1. Layered Layout: Sebelisa li-PCB tse ngata-ngata ho arola likarolo tse fapaneng tsa matšoao le ho fokotsa tšitiso ea matšoao.Karohano ea matla, fatše le likarolo tsa lipontšo ho netefatsa botsitso ba matla le botšepehi ba matšoao.
2. Litsela tsa Lipontšo tse Khutšoane le tse Otlolohileng: khutsufatsa litsela tsa mats'oao ka hohle kamoo ho ka khonehang ho fokotsa tieho le tahlehelo ea phetiso ea mats'oao.Qoba litselana tse telele tse kobehileng.
3. Differential Signal Cabling: Bakeng sa matshwao a lebelo le phahameng, sebedisa differential signal cabling ho fokotsa crosstalk le lerata.Netefatsa hore bolelele ba litselana lipakeng tsa lipara tse fapaneng boa nyallana.
4. Sefofane se fatše: Netefatsa sebaka se lekaneng sa sefofane sa fatše ho fokotsa litsela tsa ho khutla ha matšoao le ho fokotsa lerata le mahlaseli.
5. bypass le decoupling capacitors: beha li-capacitor tsa bypass pakeng tsa likhoele tsa phepelo ea matla le fatše ho tsitsisa motlakase oa phepelo.Kenya li-decoupling capacitor moo ho hlokahalang ho fokotsa lerata.
6. Phapang ka lebelo le phahameng la symmetry: Boloka bolelele ba tsela le sebopeho sa symmetry ea lipara tse fapaneng ho etsa bonnete ba hore phetisetso ea matšoao e leka-lekaneng.
Mekhoa e Molemo ka ho Fetisisa ea Tsamaiso ea Mocheso
1. Moqapi oa mocheso: Fana ka lijana tse lekaneng tsa mocheso le litsela tse pholileng bakeng sa likarolo tse phahameng tsa matla ho qhala mocheso ka katleho.Sebelisa liphaephe tsa mocheso kapa lisinki tsa mocheso ho ntlafatsa phallo ea mocheso.
2. Ponahalo ea likaroloana tse nang le kutloelo-bohloko ho mocheso: Beha likaroloana tse utloang mocheso oa mocheso (mohlala, li-processor, li-FPGA, joalo-joalo) libakeng tse loketseng ho PCB ho fokotsa ho bokellana ha mocheso.
3. Sebaka sa moea le sebaka sa ho senya mocheso: Etsa bonnete ba hore chassis kapa sebaka se koaletsoeng sa PCB se na le likhahla tse lekaneng le sebaka sa ho senya mocheso ho khothalletsa ho potoloha ha moea le ho senya mocheso.
4. Lisebelisoa tsa ho fetisa mocheso: Sebelisa lisebelisoa tsa ho fetisa mocheso, tse kang litšepe tsa mocheso le liphahlo tsa mocheso, libakeng tseo ho tsona ho hlokahalang ho senya mocheso ho ntlafatsa katleho ea mocheso.
5. Li-Sensors tsa Mocheso: Eketsa lisebelisoa tsa mocheso libakeng tse ka sehloohong ho shebella mocheso oa PCB.Sena se ka sebelisoa ho beha leihlo le ho laola sistimi ea mocheso ka nako ea nnete.
6. Thermal Simulation: Sebelisa software ea ketsiso ea mocheso ho etsisa kabo ea mocheso ea PCB ho thusa ho ntlafatsa moralo le moralo oa mocheso.
7. Ho Qoba Hot Spots: Qoba ho bokella likarolo tse phahameng tsa matla hammoho ho thibela libaka tse chesang, tse ka lebisang ho mocheso oa motsoako le ho hlōleha.
Ka kakaretso, moralo oa moralo oa PCBA o bohlokoa bakeng sa botšepehi ba matšoao le taolo ea mocheso.Ka ho latela mekhoa e metle e boletsoeng ka holimo, o ka ntlafatsa ts'ebetso le ts'epahalo ea lisebelisoa tsa hau tsa elektroniki ka ho etsa bonnete ba hore matšoao a fetisoa khafetsa ho pholletsa le boto le hore mocheso o laoloa ka nepo.Ho sebelisa papiso ea potoloho le lisebelisoa tsa tlhahlobo ea mocheso nakong ea moralo ho ka thusa ho ntlafatsa sebopeho le ho rarolla mathata a ka bang teng.Ho phaella moo, tšebelisano-'moho haufi-ufi le moetsi PCBA ke senotlolo sa ho etsa bonnete ba ho phethahatsoa ka katleho ea moralo.
Zhejiang NeoDen Technology Co., Ltd e 'nile ea etsa le ho romela mechine e fapaneng e fapaneng ea ho khetha le ho beha ho tloha ka 2010. Ho nka monyetla ka R&D ea rona e ruileng e nang le boiphihlelo, tlhahiso e koetlisitsoeng hantle, NeoDen e hapa botumo bo botle ho tsoa ho bareki ba lefats'e ka bophara.
ka boteng ba lefats'e ka bophara linaheng tse fetang 130, ts'ebetso e babatsehang, ho nepahala ho phahameng le ho tšepahala ha mechine ea NeoDen PNP e etsa hore e phethahale bakeng sa R&D, prototyping ea litsebi le tlhahiso e nyane ho isa ho e mahareng.Re fana ka tharollo ea setsebi ea sesebelisoa se le seng sa SMT.
Re lumela hore batho ba baholo le balekane ba etsa NeoDen k'hamphani e ntle haholo le hore boitlamo ba rona ba Boqapi, Phapano le Tšireletseho bo netefatsa hore othomathike ea SMT e fumaneha ho motho e mong le e mong ea ratang ho itlosa bolutu hohle.
