Sethala sa mohlala se kenyelletsa ho etsoa ha li-PCB ho sebelisoa mekhoa e tsoetseng pele ea tlhahiso e kang ho phunya laser le theknoloji ea microvia. Lisebelisoa tse kang HASL kapa OSP li sebelisoa ho etsa bonnete ba hore li tšoarella ka nako e telele le ho solderability hantle.

5. Kopano le Teko

Hang ha li-prototype li entsoe, likarolo li bokelloa holim'a liboto ho sebelisoa SMT (Surface Mount Technology) kapa THT (Through-Hole Technology). Ho latela liteko tse matla, ho kenyelletsa tlhahlobo ea motlakase, tlhahlobo ea ts'ebetso, le tlhahlobo ea tikoloho ho netefatsa hore liboto li fihlela litekanyetso tsa ts'ebetso.

6. Ntlafatso ea Moralo o Iterative

Moralo o kanna oa phetoa makhetlo a 'maloa ho latela liphetho tsa liteko, tse kenyelletsang lintlafatso kapa litokiso ho ntlafatsa ts'ebetso le ts'epahalo.

fihlela qeto e

Ha phetoho e eang likoloing tse ncha tsa eneji e ntse e potlaka, li-PCB li fetohile tsa bohlokoa bakeng sa ts'ebetso e sebetsang hantle le polokeho ea likoloi tsena. Ka mahlale a tsoetseng pele joalo ka li-PCB tsa HDI , li-PCB tse nang le maqhubu a phahameng , le li-PCB tse teteaneng tsa koporo, indasteri ea likoloi e khona ho fihlela tlhoko e ntseng e hola ea likoloi tsa motlakase tse tšepahalang le tse sebetsang hantle. Ho tloha taolong ea libeteri ho ea taolong ea enjene, li-PCB li netefatsa hore karolo e 'ngoe le e 'ngoe e sebetsa hantle, e fana ka polokeho, ts'epo le ts'ebeliso e ntle ea matla.

Ho Highleap Electronic, re ikemiselitse ho ts'ehetsa bokamoso ba likoloi tse ncha tsa matla ka ho fana ka litharollo tsa PCB tsa maemo a holimo tse etselitsoeng ho fihlela litlhoko tse thata tsa litsamaiso tsa sejoale-joale tsa likoloi. Ikopanye le rona kajeno ho ithuta hore na re ka u thusa joang ho etsa hore meralo ea hau ea NEV PCB e phele ka nepo le ka ts'epahalo.
