Lefapheng la likoloi, boleng ba likarolo tsa elektronike bo ama ka ho toba tshebetso le polokeho ea koloi, eo PCB e leng e 'ngoe ea likarolo tsa motheo. Ka hona, ho bohlokoa haholo ho khetha morekisi oa boto ea motlakase oa koloi ea PCB. Kahoo, mokhoa oa ho khetha morekisi oa boto ea elektroniki ea PCB? Kajeno ke tla u fa kenyelletso e qaqileng ho netefatsa botsitso ba ketane ea phepelo le boleng bo phahameng ba lihlahisoa.
一．Utloisisa litlhoko tse khethehileng tsa PCB ea elektroniki ea likoloi
1. Tšepahala: Li-PCB tsa elektroniki tsa likoloi li hloka ho sebetsa nako e telele ntle le ho hloleha.
2. Tšusumetso ea tikoloho: E tlameha ho ikamahanya le maemo a kang mocheso o phahameng le o tlase, liphetoho tse kholo tsa mongobo, le ho thothomela.
3. Ikamahanya le maemo a indasteri: joalo ka ISO 26262 (tekanyetso ea machaba bakeng sa litsamaiso tsa elektroniki tse amanang le polokeho ea likoloi), IPC-A-600 le IPC-6012 (litekanyetso tsa tlhahiso ea PCB le kamohelo).
二、 Lekola bokhoni le boiphihlelo ba barekisi
1. Lithuto tsa profeshenale: Hore na mofani oa thepa o na le litifikeiti tse amehang tsa tsamaiso ea boleng, joalo ka ISO 9001, IATF 16949 (mokhoa oa tsamaiso ea boleng bakeng sa indasteri ea likoloi).
2. Matla a tekheniki: Bokhoni ba ho etsa lipatlisiso le nts'etsopele ea mofani oa thepa mafapheng a tsoetseng pele a theknoloji ea PCB joalo ka phetisetso ea maqhubu a phahameng le lebelo le phahameng.
3. Litšebeletso tse ikhethileng: Hore na litharollo tsa PCB tse ikhethileng li ka fanoa ho latela litlhoko tse khethehileng tsa lisebelisoa tsa elektronike tsa likoloi.
三、 Lekola botsitso ba phepelo le pepeneneng
1. Mohloli oa lisebelisoa tse tala: Bafani ba thepa ba hloahloa ba tla sebelisa lisebelisoa tsa boleng bo holimo le ho fana ka pepenene mohloling oa thepa.
2. Matla a tlhahiso: Utloisisa lisebelisoa tsa tlhahiso ea mofani oa thepa le mela ea tlhahiso ho bona hore na ho na le matla a lekaneng a tlhahiso ho finyella litlhoko tsa hau.
3. Bokhoni ba ho arabela maemong a tšohanyetso: Ha ho ka ba le tšitiso ea phepelo, na mofani oa thepa o na le moralo oa tšohanyetso oa ho netefatsa hore tlhahiso ha e amehe?
四、Lekola mokhoa oa ho laola boleng ba mofani oa thepa
1. Mekhoa ea ho hlahloba boleng: Bafani ba thepa ba lokela ho ba le lisebelisoa le mekhoa ea tlhahlobo e felletseng, joalo ka tlhahlobo ea X-ray, tlhahlobo ea optical optical (AOI), joalo-joalo.
2. Mokhoa oa ho latella: Bafani ba PCB ba boleng bo phahameng ba tla ba le mokhoa o feletseng oa ho latella sehlahisoa o ka latellang histori ea tlhahiso le tlhahlobo ea PCB ka 'ngoe.
3. Maikutlo a bareki: Ho utloisisa maikutlo a bareki ba teng ba mofani oa thepa, haholo-holo maikutlo a bareki a amanang le koloi, ho ka fana ka boitsebiso ba bohlokoa ba litšupiso.
Ha u khetha koloi ea elektronike PCB boto mofani wa thepa, u lokela ho ka botlalo nahana ka lintlha tse ngata. Ka tlhahlobo e kaholimo, qalong u ka hlahloba barekisi ba nang le boiphihlelo indastering, bokhoni bo matla ba tekheniki, boleng bo tšepahalang le ts'ebeletso e nahanelang, ho nahanoa ka botsitso ba tšebelisano ea nako e telele. , ho khothaletsoa ho theha likamano tsa nako e telele le tse tsitsitseng tsa ts'ebelisano le bafani ba thepa ho sebetsana ka kopanelo le mathata a ka bang teng nakong e tlang indastering ea likoloi.
Litlhoko tsa ho etsa boto ea elektroniki ea PCB
Ka nts'etsopele e potlakileng ea theknoloji ea elektronike ea likoloi, PCB e ntse e sebelisoa ka ho eketsehileng
ka lisebelisoa tsa elektronike tsa likoloi. Ho tloha ho litsamaiso tsa taolo ea enjene ho ea ho li-airbag ho isa litsing tse tsoetseng pele tsa lithuso tsa ho khanna, boleng le ts'ebetso ea liboto tsa PCB li ama polokeho ea koloi ka kotloloho. Litekanyetso le litlhoko tse thata li tlameha ho lateloa ha ho etsoa liboto tsa elektroniki tsa PCB tsa koloi. Kahoo, ha re shebeng. Utloisisa litlhoko tsa ho iketsetsa liboto tsa likoloi tsa elektroniki tsa PCB.
1. Khetho ea lintho tse bonahalang
Khetho ea thepa ea liboto tsa likoloi tsa PCB e bohlokoa haholo. E ka sebetsa ka mokhoa o tsitsitseng tlas'a maemo a feteletseng a tikoloho. Mocheso o phahameng, mocheso o tlase, mongobo, ho sisinyeha le tšilafalo ke lintlha tse lokelang ho nkoa. Lisebelisoa tse sebelisoang ka tloaelo tsa boto ea PCB li kenyelletsa FR-4, PTFE (polymer) Tetrafluoroethylene) le lisebelisoa tse thehiloeng ka tšepe, joalo-joalo, li ka fana ka matla a lekaneng a mochine le botsitso ba mocheso.
2. Litlhaloso tsa moralo
Ha u etsa liboto tsa likoloi tsa elektroniki tsa PCB, litlhaloso tsa moralo li bohlokoa haholo. Hangata li koahela botenya ba boto, palo ea lihlopha, botenya ba foil ea koporo, boholo le sebaka sa liphahlo, bophara ba mela / sebaka sa mela, joalo-joalo Bakeng sa li-PCB tsa likoloi, tlhokomelo e khethehileng e boetse e hlokahala. Moqapi oa lera la eona la matla o tiisa botsitso le kabo e tšoanang ea hona joale.
3. Tsamaiso ea mocheso
Ka lebaka la litšobotsi tse phahameng tsa mocheso oa tikoloho ea likoloi, tsamaiso ea mocheso e fetohile taba ea bohlokoa ha ho etsoa liboto tsa PCB tsa likoloi tsa elektroniki. Moqapi o utloahalang oa mocheso o ke ke oa tiisa feela ts'ebetso e tsitsitseng ea likarolo tsa elektronike, empa hape o eketsa bophelo ba tšebeletso ea sehlahisoa. Mekhoa e tloaelehileng ea ho laola mocheso e kenyelletsa ho sebelisa lisebelisoa tsa substrate tse nang le conductivity e ntle ea mocheso, ho rala litsela tse sebetsang hantle tsa mocheso, le ho eketsa li-radiator kapa liphaephe tsa mocheso.
4. Ts'ebetso ea motlakase
Liboto tsa koloi tsa PCB li tlameha ho ba le thepa e ntle ea motlakase, ho kenyelletsa matla a lekaneng a dielectric, matla a ho thibela ho kenella ka matla le matla a anti-electromagnetic interference (EMI), haholo lits'ebetsong tsa polokeho le taolo ea likoloi. Mofuta ofe kapa ofe oa ho hloleha ha motlakase o ka baka litlamorao tse tebileng.
5. Teko le setifikeiti
Liboto tsohle tse hlophisitsoeng tsa elektroniki tsa PCB tsa elektroniki li hloka ho feta tekong e matla le ts'ebetso ea setifikeiti ho netefatsa ts'ebetso ea tsona le polokeho lits'ebetsong tsa nnete. Liteko tsena li ka kenyelletsa tlhahlobo ea motlakase, tlhahlobo ea ho lekana ha tikoloho, netefatso ea ts'ebetso, joalo-joalo, hape li tlameha ho latela IATF 16949, ISO 9001 le litekanyetso tse ling tsa tsamaiso ea boleng ba machaba.
6. Ho tšepahala le ho tšoarella
Ho tšepahala le ho tšoarella ha mapolanka a koloi ea PCB ke matšoao a ka sehloohong a ho lekanya tshebetso ea bona. Lisebelisoa tsa boleng bo phahameng le lits'ebetso tse tsoetseng pele li tlameha ho sebelisoa moralong le ts'ebetsong ea tlhahiso ho etsa bonnete ba hore boto ea PCB e ka tsoela pele ho sebetsa nakong eohle ea bophelo ba koloi, haholo-holo nakong ea Ha u tobane le litsela tse thata le maemo a leholimo.
7. Botsoalle ba tikoloho
Ha lefats'e le ela hloko haholo ts'ireletso ea tikoloho, indasteri ea likoloi e boetse e khothalletsa tlhahiso e tala le nts'etsopele e tsitsitseng. Tlhahiso ea liboto tsa likoloi tsa elektroniki tsa PCB le tsona li lokela ho nahanela maemo a tikoloho, joalo ka ho sebelisa solder e se nang loto le lisebelisoa tse lumellanang le maemo a tikoloho joalo ka RoHS le REACH.
Ho iketsetsa liboto tsa likoloi tsa elektroniki tsa PCB ke ts'ebetso e rarahaneng le e thata e kenyelletsang likarolo tse ngata tsa mahlale le litekanyetso, ho tloha ho khetho ea thepa ho ea ho moralo, ho tloha taolong ea mocheso ho isa ts'ebetsong ea motlakase, ho ea ho setifikeiti sa tlhahlobo le botsoalle ba tikoloho, sehokelo se seng le se seng se tlameha ho ba taolo e nepahetseng ho netefatsa sehlahisoa sa ho qetela. tshebetso le polokeho. Ka tsoelo-pele ea theknoloji le tlhokahalo ea 'maraka, litekanyetso le litlhoko tsa tlhophiso ea likoloi tsa PCB li tla tsoela pele ho fetoha ho ikamahanya le liphetoho tsa nako e tlang indastering ea likoloi.
