Ha re ntse re ithuta lisebelisoa tsa elektronike, hangata re hlokomela boto ea potoloho e hatisitsoeng (PCB) le potoloho e kopantsoeng (IC), batho ba bangata ba "ferekanngoa ka booatla" ka likhopolo tsena tse peli. Ha e le hantle, ha li thata hakaalo, kajeno re tla hlakisa phapang pakeng tsa PCB le potoloho e kopanetsoeng.
PCB ke eng?
Printed Circuit Board, e tsejoang hape e le Printed Circuit Board ka Sechaena, ke karolo ea bohlokoa ea elektroniki, sehlopha sa tšehetso sa likarolo tsa elektroniki le sejari sa khokahano ea motlakase ea likarolo tsa elektroniki. Hobane e entsoe ka khatiso ea elektronike, e bitsoa "boto ea potoloho" e hatisitsoeng.
Boto ea potoloho ea hona joale, haholo-holo e entsoe ka mohala le Surface (Pattern), Dielectric layer (Dielectric), lesoba (Ka lesoba / ka), thibela enke ea welding (Solder resistant/Solder Mask), khatiso ea skrine (Legend / Marking / Silk screen ), Phekolo ea sefahleho, Surface Finish), joalo-joalo.
Melemo ea PCB: phahameng segokanyipalo, ho tšepahala ho phahameng, designability, producibility, testability, assemblability, maintainability.
Potoloho e kopaneng ke eng?
Potoloho e kopantsoeng ke sesebelisoa se senyenyane sa elektronike kapa karolo. Ho sebelisoa ts'ebetso e itseng, likarolo le khokahano ea likhoele tse kang li-transistors, resistors, capacitors le inductors tse hlokahalang potolohong li entsoe ka sekotoana se senyane kapa likaroloana tse nyane tsa semiconductor chip kapa dielectric substrate ebe li kenngoa ka har'a khetla hore e be microstructure. ka mesebetsi e hlokahalang ea potoloho. Likarolo tsohle li kopantsoe ka mokhoa o hlophisitsoeng, ho etsa hore likarolo tsa elektronike e be mohato o moholo ho isa ho miniaturization, tšebeliso e tlaase ea matla, bohlale le botšepehi bo phahameng. E emeloa ke tlhaku “IC” potolohong.
Ho latela ts'ebetso le sebopeho sa potoloho e kopaneng, e ka aroloa ka li-circuits tse kopaneng tsa analog, potoloho e kopaneng ea dijithale le potoloho e kopaneng ea dijithale / analog.
Potoloho e kopaneng e na le melemo ea boholo bo bonyenyane, bo bobebe, terata e nyane ea lead, le ntlha ea welding, bophelo bo bolelele, ts'epo e phahameng, ts'ebetso e ntle, joalo-joalo.
Kamano lipakeng tsa PCB le potoloho e kopaneng.
Potoloho e kopantsoeng ka kakaretso e bitsoa ho kopanngoa ha chip, joalo ka boardboard ho chip ea northbridge, CPU ka hare, e bitsoa potoloho e kopaneng, lebitso la mantlha le boetse le bitsoa block e kopaneng. 'Me PCB ke boto ea potoloho eo re tloaetseng ho e tseba mme e hatisitsoe ho li-welding board tsa potoloho.
Potoloho e kopantsoeng (IC) e cheselitsoe ho boto ea PCB. Boto ea PCB ke e tsamaisang potoloho e kopaneng (IC).
Ka mantsoe a bonolo, potoloho e kopanetsoeng ke potoloho e akaretsang e kopantsoeng le chip, e leng kakaretso. Hang ha e senyehile ka hare, chip e tla senyeha. PCB e ka cheselletsa likarolo ka bo eona, 'me likaroloana li ka nkeloa sebaka haeba li robehile.
