Tawm tsam keeb kwm yav dhau los ntawm kev txhawb nqa kev loj hlob ntawm lub zog huv thoob ntiaj teb, kev tsim hluav taws xob photovoltaic tau dhau los ua kev txhim kho tseem ceeb hauv thaj chaw hluav taws xob vim nws qhov txiaj ntsig tseem ceeb xws li kev rov ua dua tshiab thiab muaj kuab paug-dawb. Raws li cov khoom siv tseem ceeb hauv kev tsim hluav taws xob photovoltaic, photovoltaic inverters ua lub luag haujlwm tseem ceeb ntawm kev hloov tam sim no rau hauv kev hloov tam sim no, thiabpcb board ntawm photovoltaic inverteryog lub hauv paus thiab lub hauv paus rau kev ua tiav kev ua haujlwm zoo thiab ruaj khov ntawm inverters. Kev ua haujlwm zoo pcb pawg thawj coj ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev ua haujlwm ntawm photovoltaic inverters, kom ntseeg tau tias muaj kev ntseeg siab ntawm cov tshuab hluav taws xob photovoltaic, thiab txhawb kev txhim kho kev lag luam photovoltaic.
Cov kev cai tshwj xeeb rau photovoltaic inverter pcb board
Lub peev xwm ua haujlwm siab: Nrog rau kev nthuav dav ntxiv ntawm photovoltaic fais fab nroj tsuag thiab kev txhim kho ntawm photovoltaic module efficiency, photovoltaic inverters yuav tsum tau ua kom muaj zog dua. Qhov no yuav tsum tau pcb boards kom muaj peev xwm nqa tau cov dej ntws siab, muaj kev sib txuas hluav taws xob zoo, thiab cov yam ntxwv tsis zoo. Piv txwv li, hauv qee qhov megawatt qib photovoltaic inverters, qee cov kab yuav tsum dhau ntau pua amperes ntawm tam sim no, yog li pcb boards feem ntau yog tsim los nrog cov ntawv ci tooj liab tuab, uas tuaj yeem ncav cuag lub thickness ntawm 3-5 ounces, kom txo tau cov kab tsis kam, txo cov hluav taws xob poob thiab hluav taws xob tsim teeb meem.
Kev kub siab ua haujlwm thiab kev ua haujlwm kub kub: Photovoltaic inverters ua kom muaj cua sov ntau thaum lub sijhawm ua haujlwm, tshwj xeeb tshaj yog nyob rau hauv siab - qhov kub thiab txias xws li sab nraum zoov photovoltaic fais fab nroj tsuag. Yog tias lub rooj tsavxwm pcb tsis tuaj yeem cuam tshuam cov cua sov, nws qhov kev ua tau zoo thiab kev ntseeg siab yuav raug cuam tshuam loj heev. Rau lub hom phiaj no, siab thermal conductivity substrates xws li ceramic substrates los yog FR-4 cov ntaub ntawv nrog tshwj xeeb tshav kub dissipation muab tub lim yuav raug xaiv thaum lub sij hawm ua. Nyob rau tib lub sijhawm, cov qauv tsim hluav taws xob tsim nyog yuav raug tsim, xws li thaj chaw loj tshav kub dissipation tooj liab, thermal conductive vias, thiab lwm yam., txhawm rau txhim kho cov cua kub dissipation muaj peev xwm ntawm pcb board thiab ua kom ruaj khov ntawm cov khoom siv hluav taws xob hauv qhov kub thiab txias.
Kev ntseeg siab thiab ruaj khov: Lub tshuab hluav taws xob photovoltaic feem ntau yuav tsum tau ua haujlwm ntev - lub sijhawm ruaj khov, thiab lawv qhov chaw ua haujlwm yog qhov nyuaj thiab sib txawv, suav nrog cov yam ntxwv xws li kub, av noo, thiab plua plav. Yog li ntawd, photovoltaic inverter pcb board yuav tsum muaj kev ntseeg siab heev thiab muaj peev xwm tiv taus qhov cuam tshuam ntawm qhov hnyav. Nyob rau hauv cov nqe lus ntawm kev siv tshuab, cov txheej txheem kev kho saum npoo av xws li electroless npib tsib xee plating los yog organic solder daim npog qhov ncauj yog siv los txhim kho corrosion kuj ntawm pcb boards; Ua tib zoo tswj cov txheej txheem vuam kom ntseeg tau tias cov pob qij txha tau ruaj khov thiab txhim khu kev qha, txo cov teeb meem xws li kev siv lub tshuab virtual thiab desoldering, thiab xyuas kom muaj kev ruaj ntseg ntawm pcb board thaum lub sij hawm ntev - siv.
Qhov tseem ceeb ntawm cov txheej txheem txheej txheem
High precision drilling and forming: Photovoltaic inverter pcb boards usually have high layers and density, requiring high-precision drilling processes. Advanced CNC drilling cov cuab yeej siv los tswj qhov drilling txoj hauj lwm thiab aperture, kom ntseeg tau tias cov phab ntsa du tsis muaj burrs lossis tawg. Rau pcb boards nrog cov duab tshwj xeeb, xws li cov laug cam los yog cov laug cam uas muaj cua sov dissipation slots, CNC molding tshuab yog siv los xyuas kom meej molding raug thiab ntug zoo, raws li kev tsim qauv.
Kev kho deg nruj: Kev kho saum npoo yog qhov tseem ceeb rau kev txhim kho corrosion thiab solderability ntawm pcb boards. Cov txheej txheem electroless npib tsib xee kub plating yog dav siv nyob rau hauv photovoltaic inverter pcb boards, uas muaj peev xwm tsim ib tug uniform thiab ntom npib tsib xee kub alloy txheej nyob rau saum npoo ntawm pcb board, muab zoo hluav taws xob kev twb kev txuas kev kawm thiab zoo heev corrosion kuj. Organic solder mask kev kho mob muaj qhov zoo ntawm cov nqi qis thiab cov txheej txheem yooj yim, uas tuaj yeem tsim cov yeeb yaj kiab tiv thaiv ntawm lub rooj tsavxwm pcb kom tiv thaiv tau tooj liab oxidation. Nyob rau tib lub sijhawm, nws tuaj yeem decompose sai thaum lub sijhawm vuam, kom ntseeg tau zoo solderability.
Kev soj ntsuam zoo thiab kev tswj xyuas
Kev ntsuas hluav taws xob ua haujlwm: Ua cov kev ntsuas hluav taws xob ua tau zoo ntawm pcb boards los ntawm cov cuab yeej siv hluav taws xob tshaj lij. Nrog rau kev soj ntsuam txuas ntxiv ntawm Circuit Court kom ntseeg tau tias tsis muaj qhov qhib lossis luv luv hauv Circuit Court; Kev ntsuas kev tiv thaiv hluav taws xob, tshuaj xyuas cov rwb thaiv tsev ntawm cov kab sib txawv thiab nruab nrab ntawm cov kab thiab hauv av; Kev ntsuam xyuas impedance los xyuas seb cov kab impedance puas ua tau raws li cov qauv tsim. Rau qee qhov tseem ceeb ntawm hluav taws xob tsis zoo, xws li lub zog poob, teeb liab kis tau tus mob qeeb, thiab lwm yam, kev ntsuas qhov tseeb thiab kev tsom xam yuav raug coj los ua kom ntseeg tau tias pcb pawg thawj coj ua tau raws li cov kev xav tau ntawm hluav taws xob ntawm photovoltaic inverter.
Kev ntsuam xyuas kev ntseeg tau: Txhawm rau simulate qhov hnyav ib puag ncig ntawm photovoltaic inverters thaum lub sijhawm ua haujlwm tiag tiag, cov kev ntsuam xyuas kev ntseeg tau ua rau ntawm pcb boards. Rau siab -kub kev laus kuaj, pcb lub rooj tsavxwm tau muab tso rau hauv qhov chaw siab - qhov kub thiab txias rau lub sijhawm ntev los ntsuas nws qhov kev ua tau zoo nyob rau hauv qhov kub thiab txias; Kev ntsuas kub ntawm kev caij tsheb kauj vab, los ntawm kev hloov pauv ntau zaus ntawm kev ua haujlwm kub ntawm lub rooj tsavxwm pcb, txhawm rau kuaj nws cov thermal qaug zog ua haujlwm; Kev ntsuas kev vibration, simulating qhov kev vibration ib puag ncig thaum kev thauj mus los thiab siv, xyuas seb cov khoom ntawm lub rooj tsavxwm pcb puas ruaj khov thiab seb cov pob qij txha puas xoob. Tsuas yog cov pcb boards uas tau dhau los ua qhov kev ntsuam xyuas kev ntseeg tau zoo tuaj yeem ua kom lawv muaj kev ntseeg siab nyob rau lub sijhawm ntev - ua haujlwm nyob rau hauv photovoltaic fais fab nroj tsuag.
