Izindlela Zokulawula Ukunwetshwa Nokufinyezwa Kwezinto Ze-FPC

Ngenisa

Izinto ze-Flexible printed circuit (FPC) zisetshenziswa kakhulu ekukhiqizeni izinto zikagesi ngenxa yokuguquguquka nokukwazi ukungena ezindaweni ezihlangene. Kodwa-ke, inselele eyodwa ebhekene nezinto ze-FPC ukunwetshwa nokufinyela okwenzeka ngenxa yokuguquguquka kwezinga lokushisa nokucindezela. Uma kungalawulwa kahle, lokhu kunwetshwa nokufinyela kungabangela ukuwohloka komkhiqizo nokwehluleka.Kule bhulogi, sizoxoxa ngezindlela ezihlukahlukene zokulawula ukunwetshwa nokufinyezwa kwezinto ze-FPC, okuhlanganisa izici zokuklama, ukukhethwa kwempahla, ukwakheka kwenqubo, ukugcinwa kwezinto ezibonakalayo, namasu okukhiqiza. Ngokusebenzisa lezi zindlela, abakhiqizi bangaqinisekisa ukwethembeka nokusebenza kwemikhiqizo yabo ye-FPC.

Isici sokuklama

Lapho uklama amasekhethi e-FPC, kubalulekile ukucabangela izinga lokunwetshwa kweminwe egoqayo lapho uklebhula i-ACF (Anisotropic Conductive Film). Isinxephezelo sangaphambi kwesikhathi kufanele senziwe ukuze kunqandwe ukunwetshwa nokugcina izilinganiso ezifiselekayo. Ukwengeza, ukwakheka kwemikhiqizo yokuklama kufanele kusatshalaliswe ngokulinganayo nangokulinganayo kulo lonke uhlaka. Ibanga elincane phakathi kwemikhiqizo emibili ye-PCS (Printed Circuit System) kufanele igcinwe ngaphezu kuka-2MM. Ukwengeza, izingxenye ezingenakhothusi kanye nezingxenye eziminyene kufanele zinyakaziswe ukuze kuncishiswe imiphumela yokunwetshwa kwempahla nokufinyela phakathi nezinqubo zokukhiqiza ezilandelayo.

Ukukhetha okubalulekile

Ukukhethwa kwezinto kudlala indima ebalulekile ekulawuleni ukunwetshwa nokufinyezwa kwezinto ze-FPC. I-glue esetshenziselwa ukumboza akufanele ibe mncane kunobukhulu be-foil yethusi ukuze kugwenywe ukugcwaliswa kweglue okwanele ngesikhathi se-lamination, okuholela ekuguqulweni komkhiqizo. Ukuqina kanye nokusatshalaliswa kweglue yizici ezibalulekile ekwandeni nasekufinyezweni kwezinto ze-FPC.

Idizayini Yenqubo

Idizayini yenqubo efanele ibalulekile ekulawuleni ukunwetshwa nokufinyezwa kwezinto ze-FPC. Ifilimu yokumboza kufanele ihlanganise zonke izingxenye ze-foil zethusi ngangokunokwenzeka. Akunconywa ukusebenzisa ifilimu emapheshana ukuze ugweme ukucindezeleka okungalingani ngesikhathi se-lamination. Ukwengeza, usayizi we-PI (i-polyimide) i-tape eqinisiwe akufanele ibe ngaphezu kwe-5MIL. Uma ingenakugwenywa, kunconywa ukwenza i-PI ethuthukisiwe lamination ngemva kokuba ifilimu yekhava icindezelwe futhi ibhakiwe.

Isitoreji sezinto ezibonakalayo

Ukuhambisana ngokuqinile nezimo zokugcina izinto ezibalulekile kubalulekile ekugcineni ikhwalithi nokuzinza kwezinto ze-FPC. Kubalulekile ukugcina izinto zokusebenza ngokwemiyalelo enikezwe umphakeli. Isiqandisi singadingeka kwezinye izimo futhi abakhiqizi kufanele baqinisekise ukuthi izinto ezisetshenziswayo zigcinwa ngaphansi kwezimo ezinconyiwe ukuvimbela noma yikuphi ukunwetshwa nokuncipha okungadingekile.

Ubuchwepheshe Bokukhiqiza

Izinhlobonhlobo zamasu okukhiqiza angasetshenziswa ukulawula ukunwetshwa nokufinyezwa kwezinto ze-FPC. Kunconywa ukubhaka izinto ngaphambi kokumba ukuze kuncishiswe ukunwetshwa nokufinyela kwe-substrate okubangelwa umswakama ophezulu. Ukusebenzisa i-plywood enezinhlangothi ezimfushane kungasiza ukunciphisa ukuhlanekezela okubangelwa ukucindezeleka kwamanzi phakathi nenqubo yokucwenga. Ukushwiba ngesikhathi sokucwenga kungancishiswa kube kuncane, ekugcineni kulawule ukunwetshwa nokufinyela. Inani le-plywood elisetshenzisiwe kufanele lithuthukiswe ukuze kuzuzwe ibhalansi phakathi kokukhiqiza okuphumelelayo kanye nokuguquguquka okuncane kwempahla.

Ekuphetheni

Ukulawula ukunwetshwa nokufinyezwa kwezinto ze-FPC kubalulekile ekuqinisekiseni ukwethembeka nokusebenza kwemikhiqizo kagesi. Ngokucabangela izici zokuklama, ukukhethwa kwezinto ezibonakalayo, ukwakheka kwenqubo, ukugcinwa kwezinto ezibonakalayo kanye nobuchwepheshe bokukhiqiza, abakhiqizi bangalawula ngempumelelo ukunwetshwa nokufinyezwa kwezinto ze-FPC. Lo mhlahlandlela ophelele uhlinzeka ngemininingwane ebalulekile ezindleleni ezahlukahlukene kanye nokucatshangelwa okudingekayo ekukhiqizweni kwe-FPC ngempumelelo. Ukusebenzisa lezi zindlela kuzothuthukisa ikhwalithi yomkhiqizo, kunciphise ukwehluleka, futhi kwandise ukwaneliseka kwamakhasimende.
