Ke mathata afe a tloaelehileng a moralo ha u sebelisa li-PCB tse thata-thata?

Ka poso ena ea blog, re tla hlahloba mathata a mang a tloaelehileng a moralo ao re tobanang le 'ona ha re sebetsa le li-PCB tse sa fetoheng le ho buisana ka maano a sebetsang a ho hlola mathata ana.

Liboto tsa potoloho tse hatisitsoeng tse feto-fetohang (PCBs) li fetotse indasteri ea lisebelisoa tsa elektroniki ka ho eketsa maemo a bonolo a moralo, ho boloka sebaka le ho matlafatsa ts'ebetso ea nako e telele. Li-PCB tsena tse thata-fetohang li fana ka melemo e meholo le ho feta ha li kopantsoe le libaka tse thata botong e le 'ngoe. Leha ho le joalo, ho sebelisa li-PCB tse thata-thata ho boetse ho tla le liphephetso tsa eona tsa moralo.

ho etsa li-PCB tse thata-flex

1. Litlhoko tsa ho kobeha le ho kheloha:

E 'ngoe ea liqholotso tse kholo ho rala li-PCB tse sa fetoheng ke ho netefatsa hore karolo e tenyetsehang e khona ho mamella ho kobeha khafetsa ntle le ho ama ts'ebetso ea eona. E le ho sebetsana le phephetso ena, baqapi ba lokela ho khetha thepa e loketseng, e kang polyimide, e nang le matla a maholo a ho kobeha le e khonang ho mamella khatello e matla ea mochine. Ho feta moo, ho tsamaisa likarolo le ho beoa ho lokela ho hlophisoa ka hloko ho qoba khatello ea maikutlo e ka lebisang ho hloleheng ha nako e ntse e ea.

2. Ho tšepahala ha khokahano:

Ho tšepahala ho li-interconnect ho bohlokoa bakeng sa li-PCB tse sa fetoheng kaha li hloka likhokahano tse tsitsitseng tsa motlakase lipakeng tsa likarolo tse thata le tse tenyetsehang. Ho netefatsa ho ts'epahala ha khokahano ho hloka ho nahanoa ka hloko ha mekhoa ea ho tsamaisa le ho emisa. Ho kobeha ho nchocho, ho otlolla ho feteletseng, kapa khatello ea maikutlo likhokahanong li tlameha ho qojoa kaha tsena li ka fokolisa khokahano le ho baka ho hloleha ha motlakase. Baqapi ba ka khetha mekhoa e joalo ka li-teardrops, li-pads tse telele, kapa likhoele tse thekeselang ho matlafatsa matla a khokahano.

3. Taolo ea mocheso:

Tsamaiso e nepahetseng ea mocheso ke ea bohlokoa bakeng sa liboto tse thata-flex ho netefatsa ts'ebetso e nepahetseng le ho thibela ho futhumala ho feteletseng. Ho kopanngoa ha libaka tse thata le tse tenyetsehang ho baka mathata a ikhethang bakeng sa ho felisa mocheso o sebetsang hantle. Baqapi ba tlameha ho nahana ka lintlha tse kang ho senya mocheso oa motsoako, ho se tšoane ha li-coefficients tsa katoloso ea mocheso pakeng tsa thepa e thata le e tenyetsehang, le tlhokahalo ea li-vias tsa mocheso ho tsamaisa mocheso hole le libaka tse mahlonoko. Ketsiso le tlhahlobo ea mocheso li ka thusa ho tseba libaka tse chesang tse ka bang teng le ho kenya tšebetsong tharollo e nepahetseng ea mocheso.

4. Ho beha likarolo le ho tsamaisa litsela:

Ho beoa le ho tsamaisa likarolo ho li-PCB tse sa fetoheng ho hloka tlhokomelo e hlokolosi ka lebaka la tšebelisano lipakeng tsa likarolo tse thata le tse tenyetsehang. Baqapi ba tlameha ho nahana ka ho kobeha le ho kobeha ha liboto tsa potoloho nakong ea kopano le ts'ebeliso. Likarolo li lokela ho beoa le ho tsamaisoa ka mokhoa oa ho fokotsa khatello ea maikutlo, ho matlafatsa botsitso ba matšoao, le ho nolofatsa ts'ebetso ea kopano. Ketsiso e pheta-phetoang le liteko li netefatsa ho beoa le ho tsamaisa likarolo ho qoba tahlehelo e sa hlokahaleng kapa ho hloleha ha mochini.

5. Mathata a Tlhahiso le Kopano:

Li-Rigid-flex board li na le tlhahiso e phahameng le ho rarahana ha kopano ho feta liboto tse thata tse tloaelehileng. Ho kopanngoa ha mekhahlelo le lisebelisoa tse ngata ho hloka mekhoa e khethehileng ea tlhahiso le lisebelisoa. Tšebelisano lipakeng tsa baqapi le bahlahisi e bohlokoa ho fetolela sepheo sa moralo ka nepo lihlahisoa tse ka hlahisoang. Ho fana ka litokomane tse hlakileng le tse qaqileng tsa moralo, ho kenyeletsoa tlhaiso-leseling e nepahetseng ea moralo, litlhaloso tsa thepa le tataiso ea kopano, e nolofatsa ts'ebetso ea tlhahiso le kopano.

6. Pontšo ea Letšoao le Lintlha tsa EMI/EMC:

Ho boloka botšepehi ba mats'oao le ho fokotsa likotsi tsa ho kena-kenana le motlakase / khokahano ea motlakase (EMI/EMC) ke lintlha tsa bohlokoa tsa moralo bakeng sa li-PCB tse sa fetoheng. Ho ba haufi ha likarolo tse thata le tse tenyetsehang ho ka hlahisa litaba tsa ho kopanya le ho kopanya. Ho rera ka hloko ho tsamaisa mats'oao, mekhoa ea ho theola fatše, le ts'ebeliso ea ts'ireletso ho ka thusa ho fokotsa mathata ana. Ho feta moo, o tlameha ho etsa bonnete ba hore o khetha likarolo tse nepahetseng tse nang le ts'ebetso e ntle ea EMI le ho latela litekanyetso le litataiso tsa indasteri.

Ka kakaretso

Le hoja li-PCB tse thata-thata li fana ka melemo e mengata mabapi le ho feto-fetoha ha moralo le ho tšoarella, li boetse li hlahisa mathata a ikhethang a moralo. Ka ho sebetsana le lintlha tse kang litlhoko tsa ho feto-fetoha ha maemo, ho tšepahala ha li-interconnect, tsamaiso ea mocheso, ho behoa ha likarolo le litsela, ho rarahana ha tlhahiso, le botšepehi ba lipontšo, baqapi ba ka hlōla mathata ana 'me ba sebelisa ka botlalo bokhoni ba theknoloji ea PCB e thata-flex. Ka ho rera ka hloko, tšebelisano 'moho le ho latela mekhoa e metle, baenjiniere ba ka etsa lihlahisoa tse atlehileng tse nkang monyetla oa moralo o thata oa PCB.
