Taw qhia
Nyob rau niaj hnub no lub hwj chim electronics, lub zog tshiab tsheb, thiab siab - zaus zog converter industries, khoom miniaturization thiab siab - lub hwj chim muaj peev xwm los ua ib tug irreversible trend. Txawm li cas los xij, raws li qib hluav taws xob nce siab thiab PCB kab nrawm nce ntxiv, qhov kev cuam tshuam tsis raug cuam tshuam rau kev nyab xeeb ntawm ntau txhiab PCB.
Rau cov tuam txhab tsim khoom B2B, nws feem ntau yog qhov yooj yim saib xyuas IR Test uas txiav txim siab txog cov khoom lag luam thiab kev nyab xeeb. Kab lus no yuav piav qhia txog lub luag haujlwm tseem ceeb ntawm kev ntsuas kev tiv thaiv hluav taws xob thiab, nrog rauSMT ntau lawm txheej txheem, piav qhia yuav ua li cas txhim kho PCBA kev ntseeg siab nyob rau hauv siab -voltage ib puag ncig los ntawm kev ua haujlwm zoo reflow soldering technologies (xws liNeoDen IN12C).
Insulation Resistance Testing yog dab tsi? Vim li cas Nws Indispensable hauv PCBA Manufacturing?
1. Txhais thiab Core Logic
Kev ntsuas kev tiv thaiv rwb thaiv tsev yog tsim los ntsuas qhov kev ua tau zoo ntawm rwb thaiv tsev ntawm cov neeg siv hluav taws xob sib txawv ntawm PCBA (xws li cov kab uas nyob ib sab, nruab nrab ntawm cov khaubncaws sab nraud povtseg, lossis nruab nrab ntawm cov ntaub qhwv). Tsis zoo li kev soj ntsuam txuas ntxiv mus lossis kev sim ua haujlwm, kev ntsuas kev tiv thaiv kev tiv thaiv feem ntau yog siv los ntsuas qhov dej ntws tam sim no raws li tsis yog - cov kab hluav taws xob.
Nyob rau hauv siab -voltage ib puag ncig, yog tias cov nqi hluav taws xob tsis zoo poob qis dua qhov kev nyab xeeb, txawm tias lub voj voog ua haujlwm ib ntus, hluav taws xob tawg lossis hluav taws xob tsiv teb tsaws muaj feem ntau tshwm sim, ua rau muaj hluav taws kub los yog ua tsis tiav tom qab cov khoom tau ua haujlwm ntawm cov neeg siv khoom tau ntau lub hlis.
2. Lub "Magnifying Glass" ntawm PCBA Manufacturing
Kev ntsuas kev tiv thaiv hluav taws xob yog suav tias yog ib qho kev ntsuas nyuaj rau kev ntsuas tag nrho kev tsim khoom zoo. Nws tsis tsuas yog kuaj pom qhov zoo ntawm lub rooj tsavxwm nws tus kheej tab sis kuj qhia meej meej ntawm:
- Kev xaiv khoom siv:Txawm hais tias qhov ntsuas hluav taws xob ntawm PCB substrate (xws li FR-4) ua tau raws li cov qauv.
- Txheej Txheem Kev Ntseeg:Txawm hais tias thermal stress thaum lub sij hawm reflow soldering txheej txheem ua rau delamination los yog microcracks nyob rau hauv substrate.
- Cov txheej txheem ntxuav:Seb puas muaj ib qho nyuaj -kom- kuaj pom ionic paug rau ntawm qhov chaw.
Thawj qhov chaw ntawm PCBA tsis ua haujlwm hauv High-Voltage Environments
Nyob rau hauv siab -voltage tej yam kev mob (feem ntau 60V DC lossis 25V AC thiab siab dua, nrog rau siab dua - qib kilovolt applications), PCBA ntsib teeb meem lub cev hnyav dua li cov khoom siv hluav taws xob zoo tib yam.
1. Cov yam ntxwv ib puag ncig: Synergistic puas los ntawm Moisture Absorption thiab plua plav
Cov ntaub ntawv PCB muaj qee qhov kev hygroscopicity. Nyob rau hauv qhov chaw siab -cov av noo, noo noo nkag mus rau micro- pores ntawm substrate, txo cov dielectric tsis tu ncua thiab ua rau poob qis hauv rwb thaiv tsev. Tsis tas li ntawd, cov hmoov av conductive los ntawm cov chaw tsim khoom lossis ib puag ncig kev ua haujlwm tuaj yeem ua raws li PCB nto, tsim txoj hauv kev zais zais uas ua rau ua rau tawg.
2. Cov txheej txheem seem: Flux Residues thiab Reactivity
Qhov no yog qhov txaus ntshai tshaj plaws hauv kev ua SMT. Txawm hais tias flux ua haujlwm tu lub sijhawm ua haujlwm, yog tias qhov reflow profile raug teeb tsa tsis raug, cov neeg ua haujlwm nquag hauv flux tsis tuaj yeem ua kom tsis muaj zog lossis kho. Nyob rau hauv ib puag ncig humid, cov residues ionize thiab tsim txoj hauv kev conductive.
3. Layout Hazards: Qhov Kev Sib Tw Heev ntawm Creepage Distance thiab Clearance
Raws li kev tsim qauv mus rau qhov ceev dua, qhov kev ncua deb ntawm lub zog thiab cov teeb liab thaj chaw txuas ntxiv zuj zus. Yog hais tias lub cev hluav taws xob clearance thiab qhov creepage deb ntsuas raws lub insulating nto tsis ua raws li tus qauv tsim, kev ntsuam xyuas kev tiv thaiv rwb thaiv tsev yuav ncaj qha chij yuam kev, prompting pab neeg tsim los kho qhov layout.
Tsim thiab Txheej Txheem Cov Lus Qhia Loop: Yuav Siv Cov Lus Qhia Li Cas Kom Ua Tau Zoo?
- Txhawb Kev Tsim Nyog Tsim Nyog: Siv cov ntaub ntawv xeem, cov kws tsim khoom tuaj yeem tshawb xyuas seb puas yog PCB pawg - nce kev tsim lossis kev kho qhov chaw ua kom muaj kev nkag siab zoo, tsis txhob cia siab rau kev suav cov theoretical nkaus xwb.
- Kev txheeb xyuas cov txheej txheem sib txawv: Yog tias qhov ntsuas hluav taws xob tiv thaiv pom qhov txawv txav hauv cov khoom loj, qhov no feem ntau qhia txog qhov sib txawv ntawm cov kauj ruam tshwj xeeb.SMT ntau lawm kab(xws lisolder paste luam ntawvthickness los yog reflow soldering ncov kub).
Txheej txheem Soldering: Ib qho tseem ceeb cuam tshuam rau kev ua haujlwm ntawm rwb thaiv tsev
Hauv kev tsim khoom SMT,reflow solderingyog cov kauj ruam tseem ceeb uas txiav txim siab qhov kawg ntawm lub cev ntawm PCBA. Rau siab -voltage PCBs, soldering yuav tsum tsis tsuas yog tsim kom muaj kev ruaj ntseg hluav taws xob kev twb kev txuas tab sis kuj xyuas kom meej qhov kev ncaj ncees ntawm lub rwb thaiv tsev system.
1. Qhov cuam tshuam ntawm Temperature Profiles ntawm Flux Residue
Yog hais tias lub sij hawm preheating thaum lub sij hawm reflow soldering tsis txaus los yog lub ncov kub yog tsawg heev, cov kuab tshuaj nyob rau hauv lub flux yuav tsis tau kiag li evaporated. Cov tshuaj no, uas nyob twj ywm "raug" nyob rau hauv los yog ib ncig ntawm lub solder pob qij txha, yog lub hauv paus ua rau tsis ua hauj lwm ntawm rwb thaiv tsev kev ntsuam xyuas.
2. Qhov tseem ceeb ntawm cov kev ntsuam xyuas ntse
Niaj hnub no SMT ntau lawm yuav tsum tau tiag tiag -lub sij hawm ntsuas kub. Los ntawm kev ntsuas qhov kub thiab txias, nws muaj peev xwm los xyuas kom meej tias txhua tus PCB tau ua tiav kev hloov pauv ntawm lub cev, ua kom cov khoom nquag hauv cov flux thiab yog li txhim kho kev ntseeg tau ntawm rwb thaiv tsev.
Cov cuab yeej muaj zog rau kev txhim kho siab -Voltage PCBA Kev ntseeg tau: NeoDen IN12C Reflow Cub
Rau siab -xav tau, siab- precision PCBA raug, NeoDen IN12C reflow qhov cub, nrog nws cov kev tshwj xeeb tshwj xeeb, ua ib qho tseem ceeb ntawm cov khoom siv los xyuas kom meej cov khoom dhau kev ntsuas kev tiv thaiv.
1. 12-Zone Design: Qhov kawg Temperature Uniformity
NeoDen IN12C nta 12 qhov chaw kub. Los ntawm cov cua kub qhov system, nws ua kom ntseeg tau tias qhov kub thiab txias sib txawv ntawm lub rooj tsavxwm tau khaws cia rau hauv qhov nqaim heev. Qhov no uniformity tiv thaiv flux residue los ntawm localized underheating, tiv thaiv rwb thaiv tsev kev ua tau zoo ntawm qhov chaw.
2. Ua -hauv Fume Filtration System: Ib puag ncig huv Soldering
Cov pa hluav taws xob tsim tawm thaum lub sij hawm ua cov txheej txheem tuaj yeem ua rau ntawm PCB nto, tsim cov khoom tsis zoo ionic. IN12C's innovative built-nyob rau hauv fume filtration system tsis yog tsuas yog ib puag ncig tus phooj ywg, tab sis kuj ua kom ib tug huv si nyob rau hauv ib puag ncig, txo qhov kev pheej hmoo ntawm txo qhov rwb thaiv tsev tiv thaiv (SIR).
3. Intelligent Temperature Profile Testing System
Lub NeoDen IN12C nta tau tsim- hauv kev ntsuas qhov ntsuas kub ntawm qhov ntsuas kub, tshem tawm qhov xav tau rau cov neeg siv los yuav cov khoom kim kim sab nraud. Qhov no tso cai rau cov neeg ua haujlwm saib xyuas lub sijhawm tiag tiag - lub sijhawm ua haujlwm ntawm cov txheej txheem soldering txhua lub sijhawm, kom ntseeg tau tias txhua txoj kev nkhaus ua tau raws li qhov xav tau nruj rau siab -voltage PCBA.
4. Kev sib npaug zoo tshaj plaws ntawm kev siv hluav taws xob thiab kev ua haujlwm siab
Tsim tshwj xeeb rauR&D thiab me me - mus rau - nruab nrab batch ntau lawm, IN12C ua tiav qis - lub zog ua haujlwm thaum tswj kev ua haujlwm siab. Rau PCBA cov tuam txhab tsom mus rau kev tswj hwm tus nqi tab sis tsis txaus siab rau kev cuam tshuam ntawm qhov zoo, qhov no yog qhov kev xaiv uas muaj qhov tshwj xeeb ROI.
Hais txog NeoDen: Koj Tus Thawj Coj Thoob Ntiaj Teb hauv Kev Ua Haujlwm SMT Kev daws teeb meem
Xaiv cov khoom siv tsis yog hais txog kev ua tau zoo, nws yog kev ntseeg siab. Txij li thaum nws tsim xyoo 2010, NeoDen Tech tau cog lus los muab ib qho - nres SMT automation kev daws teeb meem rau cov neeg siv khoom thoob ntiaj teb.
