1. Kuyini i-PCB Electroplating?
Ukufakwa kwe-PCB electroplating kubhekisela enkambisweni yokufaka ungqimba lwensimbi phezu kwe-PCB ukuze kufezwe uxhumano lukagesi, ukudluliselwa kwesignali, ukusatshalaliswa kokushisa, kanye neminye imisebenzi. Ukufakwa kwe-DC electroplating yendabuko kunezinkinga ezifana nokufana okungekuhle kokugqoka, ukujula okwanele kokufakwa kwe-plating, kanye nemiphumela yomphetho, okwenza kube nzima ukuhlangabezana nezidingo zokukhiqiza zama-PCB athuthukile njengebhodi le-High-Density Interconnect (HDI) kanye ne-Flexible Printed Circuits (FPC). Izinsiza zamandla okushintsha amaza aphezulu ziguqula amandla e-AC amakhulu abe yi-AC evame kakhulu, bese ilungiswa futhi ihlungwe ukuze ikhiqize i-DC ezinzile noma i-pulsed current. Imvamisa yazo yokusebenza ingafinyelela amashumi noma ngisho namakhulu ama-kilohertz, idlula kakhulu imvamisa yamandla (50/60Hz) yezinsiza zamandla ze-DC zendabuko. Lesi sici semvamisa ephezulu siletha izinzuzo eziningana ku-PCB electroplating.
2. Izinzuzo Zokunikezwa Kwamandla Okushintshwa Okuvame Kakhulu ku-PCB Electroplating
Ukufana Okuthuthukisiwe Kokumboza: "Umphumela wesikhumba" wemisinga yemvamisa ephezulu ubangela ukuthi umsinga ugxile ebusweni bomqhubi, okuthuthukisa ngempumelelo ukufana kokumboza nokunciphisa imiphumela yomphetho. Lokhu kuwusizo kakhulu ekufakeni izakhiwo eziyinkimbinkimbi njengemigqa emincane kanye nemigodi emincane.
Amandla Okukhulisa I-Deep Plating: Ama-current anemvamisa ephezulu angangena kangcono ezindongeni zemigodi, okwandisa ukujiya kanye nokufana kwe-plating ngaphakathi kwemigodi, okuhlangabezana nezidingo ze-plating ze-aspect ratio vias.
Ukwanda Kokusebenza Kahle Kokusebenzisa I-Electroplating: Izici zokuphendula okusheshayo kwezinsiza zamandla okushintshashintsha imvamisa ephezulu zivumela ukulawula kwamanje okunembe kakhudlwana, kunciphisa isikhathi sokufaka i-plating futhi kwandise ukusebenza kahle kokukhiqiza.
Ukusetshenziswa Kwamandla Okuncishisiwe: Izinsiza zamandla okushintshashintsha imvamisa ephezulu zinokusebenza kahle kokuguqulwa okuphezulu kanye nokusetshenziswa kwamandla okuphansi, okuhambisana nomkhuba wokukhiqiza oluhlaza.
Amandla Okufaka I-Pulse Plating: Izinsiza zamandla okushintsha imvamisa ephezulu zingakhipha kalula i-pulsed current, zivumele i-pulse electroplating. I-pulse plating ithuthukisa ikhwalithi yokumboza, yandisa ubuningi be-coating, inciphisa ukugoba, futhi inciphise ukusetshenziswa kwezithasiselo.
3. Izibonelo zezicelo zokunikezwa kwamandla kagesi okushintshashintsha imvamisa ephezulu ku-PCB Electroplating
A. I-Copper Plating: I-Copper electroplating isetshenziswa ekukhiqizweni kwe-PCB ukwakha ungqimba oluqhubayo lwesekethe. Ama-rectifier okushintsha amaza aphezulu ahlinzeka ngobuningi bamanje obuqondile, aqinisekisa ukufakwa kongqimba lwethusi olufanayo futhi athuthukise ikhwalithi kanye nokusebenza kongqimba olufakwe i-plated.
B. Ukwelashwa Komphezulu: Ukwelashwa komphezulu kwama-PCB, njengokufakwa kwegolide noma isiliva, nakho kudinga amandla e-DC azinzile. Ama-rectifier okushintsha amaza aphezulu anganikeza amandla kagesi kanye ne-voltage efanele yezinsimbi ezahlukene zokufakwa, okuqinisekisa ukushelela kanye nokumelana nokugqwala kwesembozo.
C. Ukufakwa Kwamakhemikhali: ukufakwa kwamakhemikhali kwenziwa ngaphandle kogesi, kodwa inqubo inezidingo eziqinile zokushisa kanye nobuningi bamandla kagesi. Ama-rectifier okushintsha amaza aphezulu anganikeza amandla asekelayo kule nqubo, okusiza ukulawula amazinga okufakwa kwamapayipi.
4. Indlela Yokunquma Imininingwane Yokunikezwa Kwamandla E-PCB Electroplating
Imininingwane yokunikezwa kukagesi kwe-DC okudingekayo ekufakweni kwe-PCB electroplating incike ezintweni eziningana, kufaka phakathi uhlobo lwenqubo yokufakwa kwe-electroplating, usayizi we-PCB, indawo yokufakwa kwe-plating, izidingo zobuningi bamanje, kanye nokusebenza kahle kokukhiqiza. Ngezansi kunezinye izilinganiso ezibalulekile kanye nemininingwane evamile yokunikezwa kukagesi:
