Lisebelisoa tsa elektroniki tse hatisitsoeng tsa liboto (tse tla bitsoa mona PCBLihlahisoa li ‘nile tsa sebelisoa khoebong ho tloha ka 1948’ me tsa qala ho hlaha ‘me tsa sebelisoa haholo lilemong tsa bo-1950. Indasteri ea setso ea PCB ke indasteri e sebelisang basebetsi ba bangata mme matla a eona a tekheniki a tlase ho feta a indasteri ea semiconductor. Ho tloha li-2000 tsa pele, indasteri ea semiconductor e tlohile hanyane ka hanyane ho tloha US le Japane ho ea Taiwan le China. Ho fihlela joale, China e fetohile mohlahisi ea nang le tšusumetso ho PCB lefatšeng, e ikarabellang ho feta 60% ea tlhahiso ea PCB ea lefatše.

Lisebelisoa tsa bongaka:

Tsoelo-pele ea kajeno ea mahlale a bongaka e bakoa ke kholo e potlakileng ea indasteri ea elektroniki. Most medical devices (e.g., pH meters, heart rate sensors, temperature measurements, ELECTROcardiogram/EEG, MRI devices, X-rays, CT scans, blood pressure devices, blood glucose level measuring devices, incubators, microbiological devices, etc.) are pcBS-based for individual use. Hangata li-PCBS tsena li kopane ebile li na le li-coefficients tse nyane tsa sebopeho. Lisele tsa letsoalo li bolela ho beha likaroloana tse nyane tsa SMT ka boholo bo bonyenyane ba PCB. Lisebelisoa tsena tsa bongaka li nyane, ho bonolo ho li tsamaisa, li bobebe ebile ho bonolo ho li sebetsa.

Lisebelisoa tsa indasteri.

PCBS le eona e sebelisoa haholo ho etsa thepa, lifeme le limela tse haufi. Liindasteri tsena li na le mechini e nang le matla a maholo e khannoang ke lipotoloho tse sebetsang ka matla tse hlokang tsa hona joale tse kholo. Ho etsa sena, lera le kaholimo la PCB le koahetsoe ka lera le teteaneng la koporo, leo, ho fapana le li-PCBS tse rarahaneng tsa elektroniki, le nang le matla a hona joale a fihlang ho 100 amperes. Sena se bohlokoa ka ho khetheha lits’ebetsong tse kang ho tjheseletsa arc, li-driver tse kholo tsa servo motor, lijaja tsa betri ea lead-acid, ho hlaka ha lesela la k’hothone bakeng sa indasteri ea sesole le liaparo.

Leseli

Ha ho bonesoa, lefats’e le ea tharollo ea motlakase. Li-bulbs tsena tsa halogen ha li sa fumaneha hona joale, empa joale re bona mabone a LED le li-leds tse matla haholo. These small leds provide high brightness light and are mounted on aluminum-based PCBS. Aluminium e na le thepa ea ho monya mocheso le ho o ntšetsa moeeng. Ka hona, ka lebaka la matla a maholo, li-PCBS tsena tsa aluminium li sebelisoa hangata lipotolohong tsa lebone la LED tsa lisekete tse mahareng le tse phahameng tsa matla a LED.

Koloi le sebaka sa marulelo

Kopo e ‘ngoe ea PCBS e indastering ea likoloi le ea lifofane. Ntho e tloaelehileng mona ke ho pheta-pheta lifofane kapa likoloi tse tsamaeang. Kahoo, e le ho khotsofatsa ho thothomela hona ho nang le matla a maholo, PCB e ba bonolo.

Ka hona, sebelisa PCB e bitsoang Flex PCB. PCB e tenyetsehang e ka mamella ho thothomela ho phahameng le boima bo bobebe, ka hona ea fokotsa boima ba sepakapaka. Li-PCBS tsena tse tenyetsehang le tsona li ka fetoloa sebakeng se patisaneng, e leng monyetla o moholo hape. Li-PCBS tsena tse tenyetsehang li sebetsa e le likhokelo, li-interface, ‘me li ka bokelloa libakeng tse kopaneng, joalo ka liphanele tse ka morao, tlasa li-dashboard, jj. Motsoako oa PCBS e thata le e tenyetsehang le eona e ka sebelisoa (PCBS e thata-tenyetsehang).

Ho tloha kabo ea indasteri ea kopo, lisebelisoa tsa elektroniki tsa bareki li bile le karolo e phahameng ka ho fetisisa, ho fihlela ho 39%; Lik’homphieutha li ikarabella bakeng sa 22%; Puisano 14%; Industrial controls and medical equipment accounted for 14 per cent; Elektroniki tsa likoloi li entsoe ka 6%. Ts’ireletso le Aerospace li ikarabella bakeng sa 5%, lifofane le lisebelisoa tsa bongaka le likarolo tse ling li na le litlhokahalo tse phahameng tsa ho nepahala ha PCB.

PCB e sebelisoa haholo hobane e na le menyetla e mengata e ikhethang, e ka akaretsoeng ka tsela e latelang.

1. Palo e phahameng haholo.

Ka ntlafatso ea kopanyo ea potoloho e kopaneng le theknoloji ea ho kenya, li-PCBS tse phahameng li ka ntlafatsoa.

2. Ho tšepahala ho phahameng.

Ka letoto la litlhahlobo, liteko le liteko tsa botsofali, PCB e ka netefatsoa hore e tla sebetsa ka ts’epahalo nako e telele.

3. Boikarabello.

Bakeng sa mefuta eohle ea ts’ebetso ea PCB (motlakase, ‘mele, lik’hemik’hale, mechini, jj.), Li ka emisoa ka moralo, ho beha maemo le litsela tse ling tsa ho fihlela nako ea moralo oa boto e hatisitsoeng, e sebetsa hantle haholo.

4. Ho hlahisa litholoana.

Ka botsamaisi ba sejoale-joale, maemo, boholo (bongata), boiketsetso le tlhahiso e ngoe li ka etsoa ho netefatsa botsitso ba boleng ba sehlahisoa.

Ho khoneha.

Mokhoa o batlang o felletse oa liteko, litekanyetso tsa liteko, lisebelisoa tse fapaneng tsa liteko le lisebelisoa li thehiloe ho leka le ho khetholla lihlahisoa tsa PCB bakeng sa tumellano le bophelo ba ts’ebeletso.

6. Kopano.

Lihlahisoa tsa PCB ha li tsamaise feela kopano e hlophisitsoeng ea likarolo tse fapaneng, empa hape e nolofalletsa tlhahiso e ikemetseng le e boima.

Ka nako e ts’oanang, li-PCBS le likarolo tsa kopano tsa likarolo tse fapaneng li ka bokelloa likarolo tse kholo, litsamaiso kapa mechini e felletseng.

7. Tlhokomelo.

Lihlahisoa tsa PCB le likopano tsa likarolo li hlophisitsoe hobane li entsoe le ho etsoa ka tekanyo e lekanang.

Ka tsela ena, hang ha sistimi e hloleha, e ka nkeloa sebaka ka potlako, habonolo le ka mokhoa o bonolo, mme e khutlise mosebetsi oa sistimi ka potlako.
