I-Lead Frame Material Strip

Ukusetshenziswa kweucwecwe lwethusikumafreyimu omthofu kubonakala kakhulu kulezi zici ezilandelayo:

● Ukukhetha okubalulekile:
Amafreyimu okuhola ngokuvamile ayenziwe ngama-alloys ethusi noma izinto zethusi ngoba ithusi linomoya ophezulu we-electrical conductivity kanye ne-thermal conductivity ephezulu, engaqinisekisa ukudluliswa kwesignali okuphumelelayo nokuphathwa kahle kokushisa.

●Inqubo yokukhiqiza:
I-Etching: Lapho wenza amafreyimu okuhola, kusetshenziswa inqubo yokunamathisela. Okokuqala, ungqimba lwe-photoresist lumbozwa epuleti lensimbi, bese luvezwa ku-etchant ukuze kususwe indawo engamboziwe i-photoresist ukuze kwakhe iphethini yohlaka lomthofu omuhle.

Ukugxiviza: Ifa eliqhubekayo lifakwa emshinini wokunyathelisa wesivinini esikhulu ukwenza uhlaka lomthofu ngenqubo yokugxiviza.

● Izimfuneko zokusebenza:
Amafreyimu omthofu kufanele abe nokuhamba kukagesi okuphezulu, ukuguquguquka kwe-thermal okuphezulu, amandla anele kanye nokuqina, ukuhleleka okuhle, ukusebenza okuhle kakhulu kokushisela kanye nokumelana nokugqwala.
Ama-alloys ethusi angahlangabezana nalezi zidingo zokusebenza. Amandla abo, ubulukhuni kanye nokuqina kungalungiswa ngokusebenzisa i-alloying. Ngesikhathi esifanayo, kulula ukwenza izakhiwo zefreyimu eholayo eyinkimbinkimbi futhi enembile ngokusebenzisa isitembu esinembile, i-electroplating, i-etching nezinye izinqubo.

●Ukuguquguquka kwemvelo:
Ngezidingo zemithetho yezemvelo, ama-alloys ethusi ahlangabezana nezindlela zokukhiqiza eziluhlaza ezifana ne-lead-free kanye ne-halogen-free, futhi kulula ukufeza ukukhiqizwa okuhambisana nemvelo.
Kafushane, ukusetshenziswa kwefoyili yethusi kumafreyimu omthofu kubonakala kakhulu ekukhethweni kwezinto eziyinhloko kanye nezidingo eziqinile zokusebenza enqubweni yokukhiqiza, kuyilapho kubhekwa ukuvikelwa kwemvelo kanye nokusimama.
