hom tshiab ntawm cov khoom siv hluav taws xob electroplating-high-frequency switching power supply. Nws muab cov txiaj ntsig zoo ntawm kev sib tw waveform ntawm silicon rectifiers thiab qhov yooj yim ntawm kev tswj hluav taws xob ntawm silicon-tswj rectifiers. Nws muaj qhov ua tau zoo tshaj plaws tam sim no (txog 90% lossis ntau dua) thiab qhov ntim tsawg tshaj plaws. Nws yog ib qho kev cog lus rectifier. Cov cuab yeej tsim khoom siv tau daws qhov teeb meem ntawm lub zog, thiab lub zog hloov pauv hloov hluav taws xob los ntawm ntau txhiab amps mus rau kaum tawm txhiab amps tau nkag mus rau theem ua tau zoo ntawm kev tsim khoom.
Nws ncaj qha rectifies thiab lim cov AC zog daim phiaj los ntawm EMI anti-electromagnetic cuam tshuam kab lim, converts DC voltage mus rau ib tug high-frequency square nthwv dej ntawm kaum los yog pua pua ntawm kHz los ntawm lub converter, cais thiab txo qhov voltage los ntawm high-frequency. transformer, thiab tom qab ntawd los ntawm lub siab zaus lim cov zis DC voltage. Tom qab ua piv txwv, sib piv, amplifying thiab tswj, tsav Circuit Court, lub luag hauj lwm piv ntawm lub hwj chim raj nyob rau hauv lub converter yog tswj kom tau ib tug ruaj khov tso zis voltage (los yog tso zis tam sim no).
Kev hloov lub raj ntawm lub tshuab hluav taws xob hloov hluav taws xob ua haujlwm nyob rau hauv lub xeev hloov, lub zog poob me me, qhov ua tau zoo tuaj yeem ncav cuag 75% mus rau 90%, qhov ntim me me, qhov hnyav yog lub teeb, thiab qhov tseeb thiab ripple coefficient zoo dua. dua li cov silicon rectifier, uas tuaj yeem ua rau tag nrho cov zis ntau yam. Ua tiav qhov precision xav tau los ntawm kev tsim khoom. Nws muaj peev xwm tiv thaiv tus kheej thiab tuaj yeem pib thiab nres arbitrarily nyob rau hauv load. Nws tuaj yeem txuas tau yooj yim nrog lub khoos phis tawj, uas coj tau yooj yim rau kev tsim khoom siv hluav taws xob thiab tau siv dav hauv kev lag luam PCB plating.
Nta
Siv lub sijhawm tswj kev ua haujlwm, qhov teeb tsa yooj yim thiab yooj yim, thiab lub sijhawm ua haujlwm ntawm qhov zoo thiab qhov tsis zoo tam sim no polarity tuaj yeem raug teeb tsa raws li cov txheej txheem plating.
Nws muaj peb lub xeev ua haujlwm ntawm kev hloov pauv tsis siv neeg, zoo thiab tsis zoo, thiab thim rov qab, thiab tuaj yeem hloov pauv qhov polarity ntawm cov zis tam sim no.
Lub superiority ntawm periodic commutation mem tes plating
1 Rov qab pulse tam sim no txhim kho cov thickness faib ntawm txheej, lub thickness ntawm txheej yog uniform, thiab lub leveling yog zoo.
2 Lub anode dissolution ntawm lub rov qab mem tes ua rau cov concentration ntawm cov hlau ions ntawm lub cathode nto sai sai, uas yog conducive rau siv ib tug siab pulse tam sim no ceev nyob rau hauv lub tom ntej no cathode voj voog, thiab lub siab pulse tam sim no ceev ua rau cov tsim ceev ntawm. siv lead ua nucleus sai dua qhov kev loj hlob ntawm cov siv lead ua, yog li Cov txheej yog ntom thiab ci, nrog tsawg porosity.
3. Qhov thim rov qab pulse anode stripping zoo heev txo cov adhesion ntawm cov organic impurities (xws li brightener) nyob rau hauv txheej, yog li cov txheej muaj purity siab thiab muaj zog tiv thaiv kom tsis muaj xim, uas yog tshwj xeeb tshaj yog nyob rau hauv silver cyanide plating.
4. Qhov rov qab mem tes tam sim no oxidizes hydrogen uas muaj nyob rau hauv txheej, uas tuaj yeem tshem tawm hydrogen embrittlement (xws li cov mem tes rov qab tuaj yeem tshem tawm cov co-deposited hydrogen thaum lub sij hawm electrodeposition ntawm palladium) los yog txo cov kev ntxhov siab sab hauv.
5. Lub sij hawm rov qab cov mem tes tam sim no khaws cov npoo ntawm cov plated nyob rau hauv lub xeev nquag txhua lub sijhawm, kom cov txheej txheej plating nrog kev sib txuas zoo tuaj yeem tau txais.
6. Rov qab mem tes yuav pab tau kom txo tau qhov tseeb thickness ntawm diffusion txheej thiab txhim kho cov cathode tam sim no efficiency. Yog li ntawd, cov pulse tsis zoo yuav ua rau kom tus nqi deposition ntawm txheej.
7 Nyob rau hauv lub plating system uas tsis tso cai los yog ib tug me me ntawm additives, ob chav mem tes plating yuav tau ib tug zoo, du, thiab du txheej.
Raws li qhov tshwm sim, cov txheej txheem kev ua tau zoo xws li kub tsis kam, hnav tsis kam, vuam, toughness, corrosion kuj, conductivity, tsis kam rau discoloration, thiab smoothness tau nce exponentially, thiab nws tuaj yeem txuag tau cov hlau tsis tshua muaj nqi (txog 20% -50). %) thiab txuag cov additives (xws li Bright silver cyanide plating yog li 50% -80%)
