PCB Hole Copper Plating - Via Filling Plating Lines

Karolo ea ka ho Tlatsa Plating Lines

Ka lithapo tsa ho tlatsa li bohlokoa ts'ebetsong ea tlhahiso ea PCB, ho netefatsa ts'ebetso le ts'epahalo ea lisebelisoa tsa elektroniki. Mona ke kakaretso ea likarolo tsa bona tsa bohlokoa:

1. Ho theha likhokahano tsa MotlakaseKa lithapo tsa ho tlatsa, beha lintho tse tsamaisang ka har'a li-vias tse chekiloeng ho theha likhokahano tsa motlakase lipakeng tsa likarolo tse fapaneng tsa PCB. Sena se nolofalletsa phetisetso ea lets'oao le matla ho pholletsa le mekhahlelo e mengata, e leng bohlokoa bakeng sa li-PCB tse ngata.
2. Ntlafatso ea Matla a MechiniTs'ebetso ea plating e matlafatsa li-vias, ho fana ka tšehetso ea sebopeho le ho netefatsa hore likarolo tse kentsoeng ka har'a vias tsena li tsitsitse ka mokhoa o sireletsehileng. Sena se thusa ho fokotsa kotsi ea ho sisinyeha kapa ho senyeha ha likarolo nakong ea ts'ebetso, ka hona ho matlafatsa ts'ebetso ea PCB, haholo-holo lits'ebetsong tse phahameng tsa khatello ea maikutlo.
3. Ho ntlafatsa Ts'ebetso ea MotlakaseUniform ka ho tlatsa plating e netefatsa hore ho na le motlakase o tsitsitseng, ho fokotsa tahlehelo ea matšoao le ho boloka botšepehi ba matšoao ho pholletsa le mekhahlelo. Li-vias tse pentiloeng hantle li boetse li thusa ho fokotsa mocheso hantle, ho fokotsa kotsi ea khatello ea mocheso botong.
4. Ho Bebofatsa Soldering e TšepahalangPlated vias sebetsa e le mekatelo e ka tšeptjoang ea solder bakeng sa likarolo, ho etsa bonnete ba hore manonyeletso a matla a solder pakeng tsa likarolo tse etellang pele le PCB. Sena se kenya letsoho ho likhokahano tsa boleng bo holimo tsa solder le ts'ebetso e ntlafalitsoeng ka kakaretso ea lisebelisoa tsa elektroniki.
5. E tšehetsa meralo ea PCB e tsoetseng peleKa ho tlatsa plating ho bohlokoa bakeng sa meralo e tsoetseng pele ea PCB joalo ka li-high-density interconnect (HDI) le li-PCB tse ngata. E thusa ho tsamaisa mekhoa e rarahaneng le likhokahano ka har'a boto, e ts'ehetsa nts'etsopele ea lipotoloho tse sebetsang hantle tsa elektroniki.
6. Ho nolofaletsa Tlhahiso e IkemetsengTs'ebetso ea ho tlatsa li-plating e ts'ehetsa othomathike tlhahisong, ho netefatsa tlhahiso e nepahetseng le e tsitsitseng ea PCB. Automation e thusa ho fihlela boleng bo ts'oanang, e fokotsa liphoso tsa batho, 'me e ntlafatsa katleho ea tlhahiso

Ho laolaPCB Hole Botenya ba Koporo

PCB lesoba koporo botenya e bua ka botenya ba lera koporo ka hare ho lesoba ka mor'a tshebetso plating. Paramethara ena e bohlokoa bakeng sa ho netefatsa ts'ebetso ea motlakase le matla a mochini:

• IPC-6012 Litekanyetsohangata e hloka botenya ba lesoba la koporo lipakeng tsa 20 microinches le 1 mil.
• Lintho tse kang nako ea ho pola, ho teteana ha hona joale, le boholo ba lesoba li ama botenya ba ho qetela ba koporo.
• Botenya ba sekoti bo lekaneng bo thusa ho fokotsa khanyetso, ho matlafatsa matla a mochini, le ho ntlafatsa ts'epo ea nako e telele.

Litšitiso tse Tloaelehileng tsa PCB tse Bakiloeng ke Ho Senya Koporo ea Koporo

Mefokolo e bakoang ke ho roala ka koporo e sa nepahalang e ka lebisa litabeng tse 'maloa ho li-PCB:

1. Koporo e sa Lekaneng ka Likoti: E lebisa likhokelong tse sa tsitsang tsa motlakase.
2. Voids in Holes: E baka mathata a bulehileng a potoloho.
3. Mekhahlelo ea Koporo: E ama boleng ba soldering le ts'ebetso ea motlakase.
4. Ho senyeha ha Lebota la lesoba: Liphello tsa likhokahano tse fokolang tsa marang-rang.
5. Botenya bo Feteletseng ba Koporo: E fokotsa bophara ba lesoba, e etsa hore kopano e be thata.
6. Plating e sa lekaneng: E senya ts'ebetso ea PCB ka kakaretso.
7. Ho phatloha: E tloaetse ho ebola nakong ea libaesekele tse futhumatsang kapa tsa solder.
8. Ka-Hole Cracks: E lebisa ho phetiso e mpe ea matšoao.
9. Tšebeliso e mpe ea Koporo: E etsa hore ho be le likhokahano tsa motlakase tse khaotsang.
10. Mathata a Soldering: E ama botsitso ba karolo le likhokahano tsa motlakase.

Ka ho ntlafatsa ts'ebetso ea plating, ho lekola liparamente ka hloko, le ho lokisa lisebelisoa tsa kamehla, mefokolo ena e ka fokotsoa, ​​ea netefatsa ts'ebetso ea boleng bo holimo ea koporo le ts'ebetso e tšepahalang ea PCB.

Ke phapang efe eo thepa ea boleng bo holimo e e etsang ha ho etsoa likoti tsa koporo?

Kamoo Lisebelisoa tsa ho Plating tsa Boleng bo Phahameng li Amang Koporo ea Koporo

1. Botenya bo tsitsitseng ba Koporo

• Ho tšoana: Lisebelisoa tsa boleng bo phahameng ba ho roala li tiisa hore lesela la koporo ka har'a likoti le behiloe ka ho lekana, ho boloka botenya bo tsitsitseng hohle. Sena se qoba mathata a likhokahano tse sa tsitsang kapa tahlehelo ea mats'oao ka lebaka la likarolo tse sa lekanang tsa koporo.

2. Boreleli ba Koporo

• Qetello e ntlafetseng: Theknoloji e tsoetseng pele ea ho pata e hlahisa bokaholimo ba koporo bo boreleli ntle le li-patches kapa likaroloana tse thata. Sena se ntlafatsa boleng ba solder le ts'ebetso, e lebisang ho conductivity e ntle ea motlakase le botsitso ba mechine.

3. Ho khomarela ka Matla

• Tšepahala e Ntlafetseng: Lisebelisoa tse phahameng tsa ho roala li tiisa hore koporo e khomarela ka thata marako a sekoti, e thibela ho phunya kapa ho arohana. Sena se ntlafatsa durability le ho tšepahala ha PCB ha nako e ntse e ea.

4. Ha ho na Bubbles kapa Voids

• Mefokolo e fokolang: Lisebelisoa tsa boleng bo phahameng li thibela ka katleho ho thehoa ha li-bubble kapa li-voids nakong ea ho roala, ho netefatsa hore ho na le lera le tiileng la koporo le qobang mathata a khokahanyo kapa ho hlōleha ha potoloho.

5. Keketseho ea Matla a Mechini

• Tšehetso e Molemo: Lera la koporo le hlahisoang ke lisebelisoa tse holimo-limo le fana ka tšehetso e matla bakeng sa likarolo tse kenngoa ka har'a likoti, ho fokotsa kotsi ea ho sisinyeha ha karolo kapa ho senyeha.

6. Ts'ebetso e tsitsitseng ea Motlakase

• Khanyetso e tlase: Botenya ba koporo bo sebelisitsoeng ka mokhoa o leka-lekaneng bo thusa khanyetso e tlase, ho netefatsa phallo e tsitsitseng ea hona joale le ts'ebetso e ntle ea motlakase ea PCB ka kakaretso.

7. Mathata a Fokotsa ka Mor'a Ts'ebetso

• Ho Sebelisa Habonolo: Mekhahlelo ea boleng bo phahameng ba koporo e lebisa litabeng tse fokolang nakong ea mehato ea morao-rao ea ts'ebetso, e kang ho fokotsa bophara ba lesoba kapa sekhahla sa koporo, se fokotsang litšenyehelo tsa tlhahiso le ho ntlafatsa katleho.

8. Phello e Ntle ea Mocheso

• Taolo e Ntlafetseng ea Thermal: Likarolo tsa boleng bo phahameng ba koporo li ntlafatsa mocheso oa mocheso, ho fokotsa khatello ea mocheso ho PCB le ho netefatsa ts'ebetso e tsitsitseng esita le tlas'a mocheso o phahameng.

9. Mefokolo ea Tlhahiso e Fokotseng

• Ho Nyane Rework: Ka boleng bo ntlafetseng ba plating, ho na le mefokolo e fokolang, e lebisang ho fokotsa litekanyetso tsa ho tsosolosa le ho senya, le ho ntlafatsa katleho ea tlhahiso ea kakaretso le boleng.

10. Tumellano ea Maemo a Indasteri

• Boleng bo tsitsitseng: Thepa ea boleng bo holimo hangata e kopana kapa e feta litekanyetso tsa indasteri, e netefatsa ts'ebetso e tšepahalang le boleng ba sehlahisoa sa ho qetela.

Ho sebelisa lisebelisoa tsa boleng bo holimo ho hlahisa koporo e betere, e lebisang ntlafatsong ea khokahanyo ea motlakase, matla a mochini, le ho ts'epahala ka kakaretso ha PCB.
