Mokhoa oa ho etsa mohlala oa PCB ka litlhoko tse tlase tsa lerata

Ho etsa prototyping boto ea potoloho e hatisitsoeng (PCB) e nang le litlhoko tse tlase tsa lerata e ka ba mosebetsi o boima, empa e ka finyelloa ka mokhoa o nepahetseng le kutloisiso ea melao-motheo le mekhoa e amehang.Ka poso ena ea blog, re tla hlahloba mehato le mehopolo e ka u thusang ho theha li-prototype tsa PCB tse lerata le tlase.Kahoo, a re qaleng!

1. Utloisisa lerata ho PCBs

Pele u kenella tšebetsong ea prototyping, hoa hlokahala ho utloisisa hore na lerata ke eng le hore na le ama li-PCB joang.Ho PCB, lerata le bolela mats'oao a sa batleheng a motlakase a ka bakang tšitiso le ho senya tsela ea mats'oao e lakatsehang.Lerata le ka bakoa ke mabaka a fapaneng, ho kenyelletsa ho kena-kenana le motlakase (EMI), li-loops tsa fatše, le ho bea likarolo tse sa lokelang.

2. Khetha likarolo tsa ho ntlafatsa lerata

Khetho ea likarolo e bohlokoa ho fokotsa lerata ho li-prototypes tsa PCB.Khetha likarolo tse etselitsoeng ka ho khetheha ho fokotsa mesi ea lerata, joalo ka liamplifi tsa lerata le tlase le lihloela.Ho phaella moo, nahana ka ho sebelisa lisebelisoa tsa holim'a metsi (SMDs) ho e-na le likarolo tsa ka-hole, kaha li ka fokotsa capacitance ea parasitic le inductance, kahoo e fana ka ts'ebetso e ntle ea lerata.

3. Ho beha likarolo hantle le ho tsamaisa tsela

Thero e hlokolosi ea ho behoa ha likarolo ho PCB e ka fokotsa lerata haholo.Kopanya likarolo tse utloang lerata hammoho le hole le matla a holimo kapa a maqhubu a phahameng.Sena se thusa ho fokotsa kotsi ea ho kopanya lerata lipakeng tsa likarolo tse fapaneng tsa potoloho.Ha u tsamaisa, leka ho arola mats'oao a lebelo le phahameng le mats'oao a lebelo le tlase ho thibela tšitiso e sa hlokahaleng.

4. Likarolo tsa fatše le matla

Sebaka se nepahetseng le kabo ea matla li bohlokoa molemong oa moralo oa PCB o se nang lerata.Sebelisa lifofane tse inehetseng tsa fatše le tsa matla ho fana ka litsela tsa ho khutla tse sa sebetseng hantle bakeng sa maqhubu a maqhubu a phahameng.Sena se thusa ho fokotsa ho feto-fetoha ha motlakase le ho netefatsa hore ho na le litšupiso tse tsitsitseng, ho fokotsa lerata ts'ebetsong.Ho arola mabaka a matšoao a analoge le a dijithale ho feta ho fokotsa kotsi ea tšilafalo ea lerata.

5. Theknoloji ea potoloho ea ho fokotsa lerata

Ho kenya ts'ebetsong mekhoa ea potoloho ea ho fokotsa lerata ho ka thusa ho ntlafatsa ts'ebetso ea lerata ka kakaretso ea li-prototypes tsa PCB.Mohlala, ho sebelisa li-decoupling capacitor liporong tsa motlakase le haufi le likarolo tse sebetsang ho ka hatella lerata le phahameng haholo.Ho sebelisa mekhoa ea ho sireletsa, joalo ka ho beha potoloho ea bohlokoa ka har'a likhoele tsa tšepe kapa ho eketsa tšireletso e thehiloeng fatše, ho ka fokotsa lerata le amanang le EMI.

6. Ketsiso le teko

Pele ho etsoa prototype ea PCB, ts'ebetso ea eona e tlameha ho etsisoa le ho lekoa ho tseba le ho rarolla mathata afe kapa afe a amanang le lerata.Sebelisa lisebelisoa tsa papiso ho hlahloba botšepehi ba matšoao, tlaleho bakeng sa likaroloana tsa likokoana-hloko, le ho lekola phatlalatso ea lerata.Ho feta moo, tlhahlobo e sebetsang e etsoa ho netefatsa hore PCB e fihlela litlhoko tse hlokahalang tsa lerata le tlase pele e tsoela pele ka tlhahiso.

Ka kakaretso

Li-PCB tsa prototyping tse nang le litlhoko tse tlase tsa lerata li hloka moralo o hlokolosi le ts'ebetsong ea mekhoa e fapaneng.O ka fokotsa lerata haholo moralong oa hau oa PCB ka ho khetha likarolo tse ntlafalitsoeng lerata, ho ela hloko ho beoa le ho tsamaisa likarolo, ho ntlafatsa lifofane le lifofane tsa motlakase, ka ho sebelisa mekhoa ea potoloho e fokotsang lerata, le ho etsa liteko tsa prototype ka botlalo.
