PCB blanking, imbobo kanye shape ukucutshungulwa kungaba zamukele die blanking indlela, ukuze kusetshenzwe PCB elula noma PCB nge hhayi izidingo eziphakeme kakhulu kungaba zamukele blanking indlela. Ifanele ukukhiqizwa kwezinga eliphansi kanye nenani le-PCB elinemfuneko engekho kakhulu futhi hhayi imfuneko ephezulu kakhulu yomumo, ngezindleko eziphansi.

Isibhakela:

Ukukhiqizwa kwenqwaba enkulu, uhlobo nenombolo yezimbobo kanye nokuma okuyinkimbinkimbi kwe-substrate yamaphepha ohlangothini olulodwa ne-double-emaceleni emgodini we-epoxy glass substrate, ngokuvamile esebenzisa isibhakela esisodwa noma eziningana zokufa.

Ukulungiswa komumo:

Ephrintiwe ukukhiqizwa ibhodi ivolumu enkulu panel olulodwa futhi double panel ukuma, ngokuvamile die. Ngokuya ngosayizi webhodi eliphrintiwe, lingahlukaniswa libe yifa elingaphezulu nelokuwa.

Ukucubungula okuyinhlanganisela:

Ukuze unciphise umjikelezo wokukhiqiza futhi uthuthukise umkhiqizo, i-die composite isetshenziselwa ukucubungula izimbobo nobubunjwa bephaneli elilodwa ngasikhathi sinye.

Ukucubungula ibhodi eliphrintiwe ngesikhunta, ukhiye ukuklanywa nokucutshungulwa kwesikhunta, okudinga ulwazi lobuchwepheshe lobuchwepheshe. Ngaphezu kwalokho, ukufakwa nokulungiswa kwesikhunta nakho kubaluleke kakhulu. Okwamanje, iningi isikhunta abakhiqizi PCB kusetshenzwe izimboni zangaphandle.

Izinyathelo zokuphepha zokufakwa kwesikhunta:

1. Ngokwesibalo sedizayini yokubalwa kwamandla angenalutho, usayizi wedayidi, ukuphakama kokuvalwa kokukhethwa komshini (kufaka phakathi uhlobo, ithani).

2. Qala i-punch, hlola i-clutch, i-brake, i-slider nezinye izingxenye zivamile, indlela yokusebenza inokwethenjelwa, akumele kube khona into eqhubekayo yomthelela.

3. I-pad yensimbi engaphansi kukadayi, ngokuvamile izingcezu ezi-2, kufanele igaywe kogaya ngasikhathi sinye, ukuqinisekisa ukuthi i-die ifakiwe ngokulingana nangokuma mpo. Ukubekwa kwephedi yensimbi yesikhundla sokugxuma okungavimbeli ukuthi impahla iwele ngasikhathi sinye eduze nendawo yesikhunta.

4. Lungisa amasethi amaningana wepuleti yokucindezela kanye nezikulufo ze-T-head zokucindezela ipuleti ukuze zisetshenziswe ngokuhambisana nesikhunta. Ingaphambili lepuleti lokucindezela akumele lithinte udonga oluqondile lwensimbi ephansi. Indwangu ye-Emery kufanele ibekwe phakathi kwendawo yokuxhumana futhi ngezikulufo kufanele ziqiniswe.

5. Lapho ufaka isikhunta, naka izikulufo namantongomane kulokho okungaphansi ungathinti okokufa okuphezulu (amathonsi aphezulu afe bese evala).

6. Lapho ulungisa isikhunta, zama ukusebenzisa ibhukwana hhayi imoto.

7. Ukuze uthuthukise ukusebenza okungenalutho kwe-substrate, i-substrate yephepha kufanele ifudunyezwe. Izinga lokushisa layo lize kuma-70 ~ 90 ℃ lingcono kakhulu.

Umgodi nokuma kwebhodi eliphrintiwe lokufa elinamapulangwe kunezici ezilandelayo zekhwalithi:

Iphakanyiswe yazungeza imbobo noma ucwecwe lwethusi lusontekile noma lukalayini; Kukhona imifantu phakathi kwezimbobo; Ukuphambuka kwesikhundla se-Hole noma imbobo uqobo akumi mpo; Burr; Isigaba esibi; Ibhodi eliphrintiwe lisontekile langena phansi ebhodweni; Ukulahla okusahlukanisiwe phezulu; Ujeme wemfucuza.

Izinyathelo zokuhlola nokuhlaziya zimi ngale ndlela elandelayo:

Hlola ukuthi amandla okushaya kanye nokuqina komshini wokushaya akwanele yini; Umklamo we-Die unengqondo, uqinile ngokwanele; I-convex, i-concave die kanye nekholomu yokuqondisa, ukunemba kwemikhono yemikhono kutholakala, ukufakwa kugxile, kumile mpo. Ukuthi imvume efanelekile iyalingana yini. Igebe phakathi kwe-convex ne-concave lincane kakhulu noma likhulu kakhulu ukukhiqiza ukukhubazeka kwekhwalithi, okuyinkinga ebaluleke kakhulu ekwakhiweni kwesikhunta, ukucubungula, ukulungisa amaphutha nokusetshenziswa. Imiphetho yokufa ye-convex ne-concave ayivunyelwe ukugoqwa futhi ihlungwe. I-punch ayivunyelwe ukuba ne-taper, ikakhulukazi lapho ukubhoboza izigaxa ezijwayelekile neziguquliwe akuvunyelwe. Ekukhiqizweni, kufanele njalo sinake ukuthi emaphethelweni e-convex ne-concave die ifakiwe. Ukukhipha umlomo kunengqondo, ukumelana okuncane. Phusha ibhodi lezinto ezibonakalayo, induku ebonakalayo inengqondo, amandla anele.Ubukhulu bepuleti namandla okubopha we-substrate, inani le-glue, namandla okubopha we-foil yethusi, ukushisa nomswakama nesikhathi nakho nakho kufanele kubhekwe ekuhlaziyweni kwamaphutha ekhwalithi angenalutho.
