PCB Prototyping bakeng sa Likopo tse Phahameng tsa Mocheso

Tsebisa:

Lefatšeng la kajeno le tsoetseng pele la theknoloji, Li-Printed Circuit Boards (PCBs) ke likarolo tsa bohlokoa tse sebelisoang lisebelisoa tse fapaneng tsa elektroniki. Leha PCB prototyping e le tloaelo e tloaelehileng, e ba phephetso le ho feta ha o sebetsana le lits'ebetso tsa mocheso o phahameng. Libaka tsena tse khethehileng li hloka li-PCB tse matsutla-tsutla le tse tšepahalang tse ka mamellang mocheso o feteletseng ntle le ho ama tšebetso.Ka poso ena ea blog, re tla hlahloba ts'ebetso ea prototyping ea PCB bakeng sa lits'ebetso tsa mocheso o phahameng, ho buisana ka lintlha tsa bohlokoa, lisebelisoa le mekhoa e metle.

Mathata a Phahameng a Mocheso a Phahameng a Mocheso a PCB:

Ho rala le ho etsa li-PCB bakeng sa lits'ebetso tsa mocheso o phahameng ho hlahisa mathata a ikhethang. Lintlha tse kang khetho ea thepa, ts'ebetso ea mocheso le motlakase li tlameha ho hlahlojoa ka hloko ho netefatsa ts'ebetso e nepahetseng le bophelo bo bolelele. Ho phaella moo, ho sebelisa lisebelisoa tse fosahetseng kapa mekhoa ea ho qapa ho ka lebisa litabeng tsa mocheso, ho senyeha ha matšoao, esita le ho hlōleha tlas'a maemo a phahameng a mocheso. Ka hona, ho bohlokoa ho latela mehato e nepahetseng le ho nahana ka lintlha tse itseng tsa bohlokoa ha u etsa li-PCB tsa prototy bakeng sa lits'ebetso tsa mocheso o phahameng.

1. Khetho ea lintho tse bonahalang:

Khetho ea thepa e bohlokoa katlehong ea prototyping ea PCB bakeng sa lits'ebetso tse phahameng tsa mocheso. Standard FR-4 (Flame Retardant 4) epoxy-based laminates le substrates li ka 'na tsa se khone ho mamella mocheso o feteletseng. Ho e-na le hoo, nahana ka ho sebelisa lisebelisoa tse khethehileng tse kang polyimide-based laminates (joaloka Kapton) kapa li-substrates tse thehiloeng ka ceramic, tse fanang ka botsitso bo botle ba mocheso le matla a mochine.

2. Boima le botenya ba koporo:

Lisebelisoa tse phahameng tsa mocheso li hloka boima bo phahameng ba koporo le botenya ho matlafatsa conductivity ea mocheso. Ho eketsa boima ba koporo ha ho ntlafatse feela mocheso oa mocheso empa hape ho thusa ho boloka ts'ebetso e tsitsitseng ea motlakase. Leha ho le joalo, hopola hore koporo e teteaneng e ka ba theko e boima haholo 'me ea baka kotsi e kholo ea ho loana nakong ea ts'ebetso ea tlhahiso.

3. Khetho ea likarolo:

Ha u khetha likarolo bakeng sa PCB e phahameng ea mocheso, ho bohlokoa ho khetha likarolo tse ka mamellang mocheso o feteletseng. Likarolo tse tloaelehileng li kanna tsa se tšoanelehe hobane meeli ea mocheso oa tsona hangata e tlase ho feta e hlokahalang bakeng sa lits'ebetso tsa mocheso o phahameng. Sebelisa likarolo tse etselitsoeng maemo a phahameng a mocheso, joalo ka li-capacitor tse phahameng tsa mocheso le li-resistors, ho netefatsa ho tšepahala le ho phela nako e telele.

4. Taolo ea mocheso:

Tsamaiso e nepahetseng ea mocheso e bohlokoa ha ho etsoa li-PCB bakeng sa lits'ebetso tse phahameng tsa mocheso. Mekhoa ea ho kenya ts'ebetsong e kang licheso tsa mocheso, li-vias tsa mocheso, le moralo o leka-lekaneng oa koporo o ka thusa ho senya mocheso le ho thibela libaka tse chesang tsa sebakeng seo. Ho feta moo, ho nahana ka ho beoa le ho shebana ha likarolo tse hlahisang mocheso ho ka thusa ho ntlafatsa phallo ea moea le kabo ea mocheso ho PCB.

5. Lekola 'me u netefatse:

Pele ho prototyping ea mocheso o phahameng oa PCB, liteko tse matla le netefatso li bohlokoa ho netefatsa ts'ebetso le ho tšoarella ha moralo. Ho etsa liteko tsa libaesekele tse futhumatsang, tse kenyelletsang ho pepesa PCB liphetohong tse feteletseng tsa mocheso, ho ka etsisa maemo a sebele a ts'ebetso le ho thusa ho tseba mefokolo kapa mefokolo e ka bang teng. Ho bohlokoa hape ho etsa liteko tsa motlakase ho netefatsa ts'ebetso ea PCB maemong a mocheso o phahameng.

Ha re phethela:

Prototyping ea PCB bakeng sa lits'ebetso tsa mocheso o phahameng e hloka ho shebisisa lisebelisoa, mekhoa ea moralo le taolo ea mocheso o phahameng. Ho sheba ka nģ'ane ho sebaka sa setso sa lisebelisoa tsa FR-4 le ho hlahloba mekhoa e meng e kang polyimide kapa li-ceramic-based substrates ho ka ntlafatsa haholo ho tšoarella ha PCB le ho tšepahala ha mocheso o feteletseng. Ho phaella moo, ho khetha likarolo tse nepahetseng, hammoho le leano le sebetsang la tsamaiso ea mocheso, ke habohlokoa ho finyella ts'ebetso e nepahetseng maemong a phahameng a mocheso. Ka ho kenya ts'ebetsong mekhoa ena e metle le ho etsa liteko le ho netefatsa ka botlalo, baenjiniere le baqapi ba ka atleha ho etsa li-prototypes tsa PCB tse ka mamellang ho thata ha likopo tsa mocheso o phahameng.
