Ngokukhanga okuphezulu emikhiqizweni eminingi yezimboni, ithusi libhekwa njengento ehlukahlukene kakhulu.
Ama-foil ethusi akhiqizwa izinqubo zokukhiqiza eziqondile kakhulu ngaphakathi kwesigayo se-foil esihlanganisa kokubili ukushisa okushisayo nokubandayo.
Kanye ne-aluminium, ithusi lisetshenziswa kabanzi emikhiqizweni yezimboni njengento eguquguqukayo kakhulu phakathi kwezinto zensimbi ezingenayo ayoni. Ikakhulukazi eminyakeni yamuva nje, isidingo se-copper foil besilokhu sikhula emikhiqizweni ye-elekthronikhi ehlanganisa omakhalekhukhwini, amakhamera edijithali, namadivayisi we-IT.
Ukwenziwa kwe-foil
Izindwangu zethusi ezincane zikhiqizwa nge-electrodeposition noma ukugoqa. Ukuze uthole i-electrodeposition yezinga eliphezulu ithusi kufanele lincibilike ku-asidi ukuze kukhiqizwe i-electrolyte yethusi. Lesi sixazululo se-electrolyte simpontshelwa emigqomeni ecwiliswe kancane, ejikelezayo eshajwa ngogesi. Kulezi zigubhu ifilimu elincanyana lethusi lifakwe i-electrodeposited. Le nqubo yaziwa nangokuthi i-plating.
Enqubweni yokukhiqiza yethusi ene-electrodeposited, i-copper foil ifakwa kusigubhu esizungezisayo se-titanium sisuka kusisombululo sethusi lapho sixhunywa khona kumthombo we-DC we-voltage. I-cathode inamathele esigubhu futhi i-anode icwiliswa kusisombululo se-electrolyte yethusi. Uma kusetshenziswa inkambu kagesi, ithusi lifakwa esigubhuni njengoba siphenduka ngesivinini esiphansi kakhulu. Indawo yethusi ohlangothini lwesigubhu ibushelelezi kuyilapho uhlangothi olubhekene nalo lukhuni. Lapho isigubhu sihamba kancane isivinini, ithusi liya lijiya futhi ngokuphambene nalokho. Ithusi liyakhangwa futhi liqoqwe phezu kwe-cathode yesigubhu se-titanium. Uhlangothi lwe-matte nesigubhu se-foil yethusi ludlula emijikelezweni yokwelapha ehlukene ukuze ithusi lifanele ukwenziwa kwe-PCB. Izindlela zokwelapha zithuthukisa ukunamathela phakathi kwe-copper kanye ne-dielectric interlayer ngesikhathi senqubo yokumboza ithusi. Enye inzuzo yokwelashwa ukusebenza njengama-anti-tarnish ngokunciphisa i-oxidation yethusi.
Umfanekiso 1:I-Electrodeposited Copper Manufacturing ProcessUmfanekiso 2 ubonisa izinqubo zokukhiqiza imikhiqizo yethusi egoqiwe. Imishini yokugingqa ihlukaniswe yaba izinhlobo ezintathu; okuyizigayo ezishisayo, izigayo ezibandayo nezigayo.
Amakhoyili amakhoyili amancanyana ayakhiwa futhi alashwe ngamakhemikhali nangokwemishini ngokulandelayo aze akhiwe abe yisimo sawo sokugcina. Ukubuka konke okuyisikimu kwenqubo yokugingqika kwamafoil ethusi kunikezwa kuMfanekiso 2. Ibhulokhi yethusi elijikijelwe (ubukhulu obulinganiselwe: 5mx1mx130mm) ishisisa kufika ku-750°C. Bese, ishisa igoqwe ngokuhlehlayo ezinyathelweni ezimbalwa phansi iye ku-1/10 wogqinsi lwalo lwangempela. Ngaphambi kokugoqa okubandayo kokuqala, izikali ezivela ekwelapheni ukushisa zisuswa ngokugaya. Enkambweni yokugoqa ebandayo ubukhulu buyancipha bube ngu-4 mm futhi amashidi akhiwa amakhoyili. Inqubo ilawulwa ngendlela yokuthi impahla iba yinde kuphela futhi ingashintshi ububanzi bayo. Njengoba amashidi engeke aqhubeke ukwakhiwa kulesi simo (into esebenza kanzima kakhulu) athola ukwelashwa kokushisa futhi ashiselwe cishe ku-550 ° C.
