Sivame ukubuzwa ngokuzivumelanisa nezimo. Vele, kungani ungadinga ibhodi "eliguquguqukayo"?
"Ingabe ibhodi eligoqekayo lizoqhekeka uma kusetshenziswa ithusi le-ED kulo?"
Kulesi sihloko singathanda ukuphenya ngezinto ezimbili ezahlukene (i-ED-Electrodeposited kanye ne-RA-rolled-annealed) bese sibona umthelela wazo ebude besikhathi besifunda. Nakuba ziqondwa kahle yimboni ye-flex, asiwutholi lowo myalezo obalulekile kumklami webhodi.
Ake sithathe isikhashana sibukeze lezi zinhlobo ezimbili ze-foil. Nansi indlela i-RA Copper kanye ne-ED Copper ezibhekwa ngayo:
Ukuguquguquka kwethusi kuvela ezintweni eziningi. Yiqiniso, okunciphile yithusi, ibhodi liguquguquka kakhulu. Ngaphezu kobukhulu (noma ubuncane), okusanhlamvu kwethusi nakho kuthinta ukuguquguquka. Kunezinhlobo ezimbili ezivamile zethusi ezisetshenziswa emakethe ye-PCB kanye ne-flex circuit: i-ED kanye ne-RA njengoba kushiwo ngenhla.
I-Roll Anneal Copper Foil (ithusi le-RA)
Ithusi Eligoqiwe Elihlanganisiwe (RA) selisetshenziswe kakhulu ekukhiqizeni amasekethe aguquguqukayo kanye nasembonini yokukhiqiza ama-PCB aqinile aguquguqukayo amashumi eminyaka.
Isakhiwo sezinhlamvu kanye nobuso obubushelelezi kulungele ukusetshenziswa kwesekethe okuguquguqukayo nokuguquguqukayo. Enye indawo ethakazelisayo ngezinhlobo zethusi ezigoqiwe ikhona ezimpawini nasezinhlelweni ezivame kakhulu.
Kuye kwafakazelwa ukuthi ukugoba kobuso bethusi kungathinta ukulahlekelwa kokufakwa okuvama kakhulu futhi ubuso bethusi obubushelelezi buyinzuzo.
I-Electrolysis Deposition Copper Foil (ithusi le-ED)
Ngethusi le-ED, kunezinhlobonhlobo ezinkulu zama-foil maqondana nobulukhuni bomphezulu, ukwelashwa, isakhiwo sezinhlamvu, njll. Njengesitatimende esijwayelekile, ithusi le-ED linesakhiwo sezinhlamvu esiqondile. Ithusi le-ED elijwayelekile livame ukuba nephrofayili ephezulu noma indawo eqinile uma kuqhathaniswa nethusi le-Rolled Annealed (RA). Ithusi le-ED livame ukungabi nokuguquguquka futhi alikhuthazi ubuqotho obuhle besignali.
Ithusi le-EA alifaneleki emigqeni emincane kanye nokumelana okubi kokugoba ngakho ithusi le-RA lisetshenziselwa i-PCB eguquguqukayo.
Kodwa-ke, asikho isizathu sokwesaba i-ED copper ekusetshenzisweni okuguquguqukayo.
Kodwa-ke, asikho isizathu sokwesaba ithusi le-ED ekusetshenzisweni okuguquguqukayo. Ngokuphambene nalokho, kuyindlela yokuzikhethela ekusetshenzisweni kwabathengi okuncane, okulula okudinga amazinga aphezulu omjikelezo. Okuwukuphela kokukhathazeka ukulawula ngokucophelela ukuthi sisebenzisa kuphi i-plating "eyengeziwe" yenqubo ye-PTH. I-RA foil ukuphela kokukhetha okutholakalayo kwezisindo zethusi ezisindayo (ngaphezu kwe-1 oz.) lapho kudingeka khona izinhlelo zokusebenza zamanje ezisindayo kanye nokuguquguquka okuguquguqukayo.
Ukuze uqonde izinzuzo kanye nokungalungi kwalezi zinto ezimbili, kubalulekile ukuqonda izinzuzo kokubili ezindleko kanye nokusebenza kwalezi zinhlobo ezimbili ze-copper foil kanye, okubaluleke kakhulu, ukuthi yini etholakala kwezentengiselwano. Umklami udinga ukucabangela hhayi nje kuphela ukuthi yini ezosebenza, kodwa nokuthi ingatholakala yini ngentengo engeke isuse umkhiqizo wokugcina emakethe ngokwentengo.
