1.Ni ubuhe buryo amashanyarazi ya PCB?
Amashanyarazi ya PCB bivuga inzira yo gushira icyuma hejuru yicyuma cya PCB kugirango ugere kumashanyarazi, guhererekanya ibimenyetso, gukwirakwiza ubushyuhe, nibindi bikorwa. Imashanyarazi gakondo ya DC ihura nibibazo nkuburinganire buke, uburebure budahagije, hamwe ningaruka zingaruka, bigatuma bigorana kuzuza ibyifuzo byinganda za PCB ziteye imbere nka High-Density Interconnect (HDI) hamwe na Flexible Printed Circuits (FPC). Amashanyarazi menshi yo guhinduranya ibikoresho ahindura imiyoboro ya AC imbaraga kuri AC-yumurongo mwinshi, hanyuma igakosorwa ikayungururwa kugirango itange DC ihamye cyangwa ihindagurika. Imirongo ikora irashobora kugera kuri mirongo cyangwa amagana ya kilohertz, irenze kure ingufu z'amashanyarazi (50 / 60Hz) z'amashanyarazi gakondo ya DC. Ibi-byinshi-biranga bizana inyungu nyinshi kuri PCB amashanyarazi.
2.Ibyiza byo Guhinduranya-Amashanyarazi Yinshi-Amashanyarazi muri PCB Amashanyarazi
Kunoza uburyo bwiza bwo gutwikira: "Ingaruka yuruhu" yumuvuduko mwinshi utuma umuyaga uhurira hejuru yumurongo wa kiyobora, bikanoza neza uburinganire bwimyenda no kugabanya ingaruka mbi. Ibi ni ingirakamaro cyane mugushiraho ibice bigoye nkimirongo myiza na micro-umwobo.
Ubushobozi bwimbitse bwimbaraga: Umuyoboro mwinshi urashobora kwinjirira neza kurukuta rwumwobo, ukongera umubyimba nuburinganire bwisahani imbere yumwobo, ibyo bikaba byujuje ibyangombwa bisabwa kugirango ugereranye cyane.
Kongera ingufu za Electroplating Efficient: Ibisubizo byihuse biranga ibintu byihuta byoguhindura amashanyarazi bitanga uburyo bunoze bwo kugenzura neza, kugabanya igihe cyo gufata no kongera umusaruro.
Kugabanya Gukoresha Ingufu: Ibikoresho byinshi byo guhinduranya amashanyarazi bifite imbaraga nyinshi zo guhindura no gukoresha ingufu nke, bigahuza nuburyo bwo gukora icyatsi.
Ubushobozi bwo Gufata Amashanyarazi: Ibikoresho byinshi byoguhindura amashanyarazi birashobora gusohora byoroshye amashanyarazi, bigafasha amashanyarazi. Isahani ya pulse itezimbere ubuziranenge, yongera ubwinshi bwikibiriti, igabanya ubukana, kandi igabanya imikoreshereze yinyongera.
3.Urugero rwumuvuduko mwinshi wo guhinduranya amashanyarazi muri PCB amashanyarazi
A. Gufata umuringa: Gukoresha amashanyarazi bikoreshwa mu gukora PCB kugirango bigire urwego ruyobora uruziga. Ikosora ryinshi ryogukosora ritanga ubucucike bugezweho, byemeza ko umuringa uhuriweho hamwe no kuzamura ubwiza nigikorwa cyurwego rushyizweho.
B. Kuvura Ubuso: Kuvura hejuru ya PCBs, nka zahabu cyangwa isahani ya feza, nabyo bisaba imbaraga za DC zihamye. Ikosora ryihuta cyane irashobora gutanga imiyoboro ikwiye hamwe na voltage kumyuma itandukanye ya plaque, bigatuma ubworoherane hamwe no kwangirika kwifata.
C. Gutera imiti: isahani yimiti ikorwa idafite amashanyarazi, ariko inzira ifite ibisabwa cyane kubushyuhe nubucucike bwubu. Ikosora ryihuta cyane irashobora gukosora imbaraga zifasha muriki gikorwa, zifasha kugenzura ibiciro bya plaque.
4.Ni gute Wamenya PCB Amashanyarazi Yerekana Amashanyarazi
Ibisobanuro by'amashanyarazi ya DC asabwa kuri PCB amashanyarazi biterwa nibintu byinshi, harimo ubwoko bwibikorwa bya electroplating, ingano ya PCB, agace ka plaque, ibisabwa byubu, hamwe nubushobozi bwo gukora. Hano haribintu bimwe byingenzi nibisanzwe bitanga amashanyarazi:
A. Ibisobanuro biriho
Ens Ubucucike bwa none: Ubucucike buriho kuri PCB amashanyarazi buri hagati ya 1-10 A / dm² (ampere kuri decimeter kare), bitewe nuburyo bwo gukwirakwiza amashanyarazi (urugero, umuringa, umuringa, zahabu, isahani ya nikel) nibisabwa.
Ibisabwa byose muri iki gihe: Igisabwa cyose kigezweho kibarwa hashingiwe ku gace ka PCB n'ubucucike buriho. Urugero:
FNiba agace ka PCB gafite 10 dm² naho ubucucike buriho ni 2 A / dm², ibisabwa byose byaba 20 A.
OrKuri PCB nini cyangwa umusaruro mwinshi, amperes magana cyangwa nibisohoka hejuru birashobora gukenerwa.
Ibisanzwe Muri iki gihe:
PC PCB nto cyangwa gukoresha laboratoire: 10-50 A.
Production Umusaruro uringaniye wa PCB: 50-200 A.
PC PCB nini cyangwa umusaruro mwinshi: 200-1000 A cyangwa irenga
B. Ibisobanuro bya Voltage
⬛PCB amashanyarazi muri rusange isaba voltage yo hasi, mubisanzwe murwego rwa 5-24 V.
Requirements Ibisabwa n’umuvuduko biterwa nimpamvu nko kurwanya ubwogero bwa plaque, intera iri hagati ya electrode, hamwe nubushobozi bwa electrolyte.
OrKu buryo bwihariye (urugero, impanuka ya pulse), hashobora gukenerwa ingufu za voltage nyinshi (nka 30-50 V).
Umuvuduko rusange w'amashanyarazi:
DC Amashanyarazi ya DC asanzwe: 6-12 V.
Ating Gufata amasahani cyangwa inzira yihariye: 12-24 V cyangwa irenga
Ubwoko bw'amashanyarazi
Supply Amashanyarazi ya DC: Yakoreshejwe mumashanyarazi gakondo ya DC, atanga amashanyarazi ahamye na voltage.
Supply Amashanyarazi atangwa: Yifashishijwe muri pulse electroplating, ishoboye gusohora amashanyarazi menshi-yihuta kugirango azamure ubwiza bwa plaque.
Supply Amashanyarazi menshi-Guhindura Amashanyarazi: Gukora neza no gusubiza byihuse, bikwiranye nibisabwa na electroplating ibisabwa.
C. Amashanyarazi
Amashanyarazi (P) agenwa nubu (I) na voltage (V), hamwe na formula: P = I × V.
Kurugero, amashanyarazi asohora 100 A kuri 12 V yaba afite ingufu za 1200 W (1,2 kW).
Urwego Rusange Imbaraga:
Equipment Ibikoresho bito: 500 W - 2 kWt
Equipment Ibikoresho bingana hagati: 2 kW - 10 kWt
Equipment Ibikoresho binini: 10 kW - 50 kW cyangwa irenga
Igihe cyo kohereza: Gashyantare-13-2025
