Capel Kopana le Litlhoko tsa Moqapi oa Lebelo le Phahameng la EMC tsa Lipotoloho tse rarahaneng tsa PCB

Tsebisa:

Lefatšeng le ntseng le fetoha ka potlako la moralo o hatisitsoeng oa potoloho (PCB), ho fihlela litlhoko tsa mats'oao a lebelo le phahameng le ho lumellana ha motlakase (EMC) ke phephetso e boima. Ha tsoelo-pele ea theknoloji le lisebelisoa tsa elektronike li ntse li rarahana le ho feta, ho na le tlhokahalo e ntseng e eketseha ea lipotoloho tse rarahaneng tsa PCB tse khonang ho sebetsana le matšoao a lebelo le phahameng ha li ntse li boloka ho lumellana ha motlakase.Ho blog ena, re tla hlahloba bokhoni ba Capel e mocha oa mmaraka mme re buisane ka hore na e ka khona ho fihlela litlhoko tsa ho bonts'a lebelo le holimo le moralo oa EMC oa lipotoloho tse rarahaneng tsa PCB.

Ithute ka moralo oa mats'oao a lebelo le phahameng:

Moralo oa mats'oao a lebelo le phahameng o phetha karolo ea bohlokoa ho lekanyeng ts'ebetso ea lisebelisoa tsa elektroniki. Lithapo tsa phetisetso ea maqhubu a phahameng le mats'oao a dijithale a feto-fetohang ka potlako a hloka botsitso bo botle ba mats'oao ho thibela litaba tse fapaneng tsa bots'epehi ba matšoao joalo ka crosstalk, reflections, le ho sotha matšoao. Ho fihlella ts'ebetso e ntle ea mats'oao a lebelo le phahameng ho hloka ho nahanoa ka hloko joalo ka taolo ea trace impedance, impedance e laoloang le tlhahlobo ea botšepehi ba matšoao.

Moqapi oa Tšebelisano ea Motlakase (EMC):

EMC e etselitsoe ho netefatsa hore lisebelisoa tsa elektroniki li sebetsa 'moho tikolohong ea motlakase ntle le ho baka tšitiso kapa ho ba le tšitiso. Moralo o nepahetseng oa EMC o kenyelletsa ho fokotsa mahlaseli a motlakase a hlahisoang ke PCB le ho eketsa tšireletso ea potoloho ho tšitiso ea kantle ea motlakase (EMI). Litaba tsa EMC li ka rarolloa ka katleho ka ho latela mekhoa ea phokotso ea lerata joalo ka ho beha fatše ka nepo, ho tsamaisa mats'oao, ho sireletsa, le ho kopanya.

Mabapi le Capel:

Capel ke software e ncha ea moralo oa PCB e ipolelang hore e ntlafatsa moralo oa mats'oao a lebelo le EMC. E fana ka likarolo tse tsoetseng pele le ts'ebetso e etselitsoeng ho rarolla mathata a amanang le lipotoloho tse rarahaneng tsa PCB. Ha re shebeng tse ling tsa likarolo tsa eona tsa bohlokoa ka botebo:

1. Tlhahlobo ea matšoao a lebelo le phahameng:

Capel e fana ka lisebelisoa tsa morao-rao tsa lisebelisoa tsa tlhahlobo ea matšoao a lebelo le phahameng tse nolofalletsang baqapi ho bolela esale pele ka nepo le ho sekaseka litaba tsa botšepehi ba matšoao. Ka calculator ea eona ea impedance, baqapi ba ka etsa bonnete ba ho tsamaisana ho laoloang, ho fokotsa lipontšo le ho boloka botšepehi ba matšoao. Ho phaella moo, Capel e fana ka bokhoni bo tsoetseng pele ba ho etsisa ho khetholla le ho fokotsa crosstalk, ho netefatsa hore phetiso ea matšoao a phahameng a phahameng a tšepahala.

2. Tlhahlobo le ntlafatso ea EMC:

Capel e totobatsa bohlokoa ba tlhahlobo ea EMC ho tloha methating ea pele ea moralo oa PCB. E fana ka li-module tsa papiso ho thusa ho tseba mehloli e ka bang teng ea tšitiso ea motlakase (EMI) le ho lekola tšusumetso ea bona lipotolohong. Ka ho sebelisa mekhoa e tsoetseng pele ea tlhahlobo ea EMC, baqapi ba ka tseba le ho rarolla mathata a ka bang teng a khokahano ea motlakase ho netefatsa hore ba latela litekanyetso tsa indasteri.

3. Tlhokomelo ea Molao oa Moqapi (DRC) le Netefatso ea Moralo:

Capel e na le licheke tse ngata tsa melao ea moralo tse nolofalletsang baqapi ho netefatsa meralo ea bona ea PCB khahlano le lets'oao le felletseng la lebelo le phahameng le litlhoko tsa moralo oa EMC. DRC e netefatsa hore melao ea bohlokoa ea moralo ea phethahala, e thibela mefokolo e ka bang teng ea moralo le ho netefatsa ts'ebetso e nepahetseng.

4. Tšebelisano 'moho le kopanyo:

Capel e lumella tšebelisano e se nang moeli pakeng tsa litho tsa sehlopha, e nolofalletsang puisano ea nako ea sebele le tsamaiso ea morero. Ho phaella moo, e fana ka kopanyo le lisebelisoa tse tloaelehileng tsa moralo le software, e lumellang baqapi hore ba sebetse ka har'a mokhoa oo ba o ratang oa mosebetsi ha ba ntse ba sebelisa matla a Capel.

Ha re phethela:

Ha lisebelisoa tsa elektroniki li ntse li tsoela pele ho fetoha, tlhokahalo ea li-PCB tse tšepahalang tse ka fihlelang lipontšo tsa lebelo le holimo le litlhoko tsa moralo oa EMC e se e le bohlokoa haholo. Le hoja Capel, e mocha 'marakeng, a tšepisa ho rarolla mathata ana ka likarolo tsa eona tse tsoetseng pele le ts'ebetso, baqapi ba tlameha ho hlahloba ka botlalo bokhoni ba eona le ho hlahloba hore na e finyella litlhoko tsa bona tse khethehileng tsa moralo joang. Ka ho fumana tekatekano e nepahetseng lipakeng tsa moralo oa mats'oao a lebelo le holimo le lintlha tsa EMC, baqapi ba ka netefatsa lipotoloho tse matla le tse sebetsang hantle tsa PCB tse behang mehato e mecha bakeng sa lisebelisoa tsa elektroniki tsa kamoso.
