Taw qhia
Hauv kev lag luam Electronic Manufacturing Services (EMS) thiab kho vajtse R&D, Surface Mount Technology (SMT) tau dhau los ua tus qauv kev lag luam. Hauv lubSMT txheej txheem sib dhos, reflow soldering yog undoubtedly "cov kauj ruam tseem ceeb" uas txiav txim siab qhov kawg khoom zoo. Txawm hais tias koj yog tus thawj tswj hwm ntawm SMT lub Hoobkas, tus kws tsim khoom siv hluav taws xob, lossis tus tsim khoom siv hluav taws xob, kev paub txog cov ntsiab lus tseem ceeb thiab cov txheej txheem kev ua haujlwm ntawm reflow soldering tsis tau tsuas yog txo cov nqi tsis zoo tab sis kuj ua kom zoo dua cov nqi tsim khoom thiab txhim kho kev lag luam kev sib tw.
Kab lus no yuav pib nrog cov hauv paus ntsiab lus ntawm reflow soldering, delve rau hauv cov tswv yim rau kev teeb tsa qhov kub thiab txias profiles, thiab, los ntawm kev hais txog kev lag luam mob cov ntsiab lus, tshawb nrhiav vim li casNeoDen IN12Ctau dhau los ua cov khoom siv ntawm kev xaiv raume thiab nruab nrab- cov kab ntau lawm PCBAthiab R&D Laboratory.
Dab tsi yog Reflow Soldering?
Reflow soldering yog ib txoj hauv kev uas ua tiav kev sib txuas ntawm cov tshuab thiab hluav taws xob ntawm qhov chaw -mount cov khoom thiab PCB substrate los ntawm remelting cov muab tshuaj txhuam -zoo li mos solder ua ntej- siv rau PCB pads. Piv nrog rau phau ntawv soldering, reflow soldering muaj qhov zoo xws li kev ua haujlwm siab, zoo sib xws, thiab tsim nyog rau ntau lawm.
Raws li theoretical piav qhia nyob rau hauv lubNeoDen IN12C siv phau ntawv, tus txheej txheem reflow soldering feem ntau muaj 4 theem:
- Preheating Zone:PCB yog rhuab los ntawm chav tsev kub mus rau qhov ua kom kub. Cov cua kub thaum lub sij hawm theem no yuav tsum tau tswj ntawm 1-3℃/ thib ob. Tus nqi nrawm dhau tuaj yeem ua rau cov khoom siv ceramic tawg, thaum qeeb qeeb tuaj yeem ua rau cov dej ntws tawm ntxov ntxov.
- Soaking / Active Zone:Qhov kub yog khaws cia ntawm kwv yees li 150-190 degree. Lub hom phiaj tseem ceeb yog los xyuas kom meej qhov kub thiab txias faib thoob plaws hauv PCB thiab cov khoom siv, qhib cov flux, thiab tshem tawm cov oxides.
- Reflow Zone:Qhov kub nce mus txog qhov siab tshaj plaws (feem ntau 230-250 degree), melting lub solder los tsim cov pob qij txha. Cov theem no yuav tsum kav 10-60 vib nas this. Yog tias nws ntev dhau lawm, cov hmoov hlau yuav oxidize.
- Cooling Zone:Lub solder pob qij txha solidify. The ideal cooling curve should mirror the reflow zone to ensure a dense crystalline structure and higher strength in the solder joints.
Nkag siab txog plaub theem no yog lub hauv paus rau kev txhim kho cov txheej txheem sib dhos SMT.
Lub tswv yim tseem ceeb: Yuav ua li cas los teeb tsa qhov zoo meej Reflow Soldering Temperature Profile?
Qhov kub ntawm qhov profile yog lub plawv ntawm reflow soldering, nws ncaj qha txiav txim siab cov txiaj ntsig soldering.
1. Nkag siab txog kev sib raug zoo ntawm qhov chaw kub thiab txias ntawm lub conveyor
NeoDen IN12C nta 12 qhov kub thiab txias (6 sab sauv / 6 qis), tso cai rau nws simulate qhov ntsuas kub zoo tshaj qhov tseeb dua li cov khoom siv 6-zone. Qhov chaw kub ntau dua muaj, qhov zoo dua rau kev tswj hwm qhov kub thiab txias gradients. Conveyor ceev txiav txim lub sij hawm nyob ntawm PCB nyob rau hauv txhua cheeb tsam kub. Ib tug raug soldering profile yuav tsum tau cua sov lub sij hawm ntawm 3-4 feeb. Users should configure settings based on PCB size, thickness, and component density, in conjunction with the parameter tables provided by the solder paste manufacturer.
2. Tiag -Tsev Sijhawm Saib Xyuas thiab Kev Pom Cov Ntaub Ntawv
Lub NeoDen IN12C tau nruab nrog qhov ntsuas kub ntsuas qhov ntsuas qhov ntsuas kub. Los ntawm kev sib txuas cov ntsuas kub, cov cuab yeej tuaj yeem tso tawm tiag -lub sijhawm ntsuas kub ntawm PCB nto. Phau ntawv qhia kom ruaj ntseg thermocouples ntawm PCB pads thiab cov khoom ua rau kom tau txais cov ntaub ntawv raug tshaj plaws. Los ntawm kev sib piv qhov ntsuas qhov nkhaus nrog tus qauv nkhaus, cov kws ua haujlwm tuaj yeem ua kom zoo - kho qhov kub thiab txias hauv txhua cheeb tsam kom ntseeg tau tias qhov ntsuas kub ntawm lub rooj tsavxwm sib phim tus nqi teev.
3. Customized Settings rau txawv PCBs
Muab ob npaug rau- txheej, ntau- txheej, thiab tuab-PCBs tooj liab muaj peev xwm nqus tau cov cua sov ntau dua thiab yuav tsum tau muaj qhov kub thiab txias dua los yog qeeb dua conveyor speeds, thaum ib zaug -txheej lossis ntawv-raws li PCBs yuav tsum tau qis dua kub los tiv thaiv overheating thiab warping. IN12C txhawb nqa kev khaws cia ntawm 40 cov ntaub ntawv ua haujlwm, tso cai rau kev rov qab sai ntawm cov zaub mov txawv rau cov khoom sib txawv thiab txhim kho kev hloov pauv kev ua haujlwm zoo.
Phau Ntawv Qhia Beginner Kom Zam Txim Pitfalls
Nyob rau hauv qhov tseeb ntau lawm, soldering defects yog inevitable. Raws li NeoDen IN12C phau ntawv daws teeb meem, ntawm no yog cov teeb meem tshwm sim thiab lawv cov kev daws teeb meem:
- Tin Pob:Feem ntau tshwm sim los ntawm ntau dhau flux evaporation vim ceev heev preheating. Qhov kev daws teeb meem yog txo qhov kub ntawm qhov ntsuas kub los yog txo qhov kub ntawm preheating cheeb tsam.
- Tsis tiav Reflow:Tej zaum yuav tshwm sim los ntawm cov cua kub tsis txaus los yog cov nyhuv duab ntxoov ntxoo. Nws raug nquahu kom txo qis cov conveyor ceev lossis nce cua sov hauv qab.
- PCB Warping:Ua los ntawm qhov kub thiab txias ntau qhov sib txawv ntawm sab saum toj thiab hauv qab. Txo qhov kub ntawm qhov sib txawv ntawm thaj tsam preheat thiab hauv qab cua sov cheeb tsam, los yog nce lub conveyor ceev.
- Ob -Sided Soldering Challenges:Rau ob-sab PCBs, nws raug nquahu kom solder Side A ua ntej, tom qab ntawd tig lub rooj tsavxwm thiab solder Side B. Lub IN12C txhawb nqa lub sab saum toj- cua sov lub tswv yim los xyuas kom meej tias cov khoom nyob rau hauv uas twb muaj lawm - soldered Side A tsis txhob detach vim kub kub.
Tsis tas li ntawd, ib puag ncig odors thiab fume extraction yog cov ntsiab lus mob tseem ceeb hauv chav kuaj. Cov cuab yeej siv niaj hnub xav tau cov fume extraction ducts sab nraud, uas yog qhov nyuaj rau nruab. Lub NeoDen IN12C nta ib qho ua tau -nyob rau hauv soldering fume filtration system uas zoo lim cov pa phem. Nws tuaj yeem siv rau hauv cov chaw ua haujlwm txheem lossis chav huv huv yam tsis muaj kev ua haujlwm sab nraud, ua rau ob qho tib si ib puag ncig thiab tiv thaiv cov neeg ua haujlwm noj qab haus huv.
Vim li cas NeoDen IN12C yog qhov kev xaiv zoo tshaj plaws rau PCBA cov tuam txhab thiab R & D lub chaw soj nstuam?
Rau cov tuam txhab, cov khoom siv xaiv tsis yog nyob ntawm kev ua tau zoo xwb tab sis kuj yog ROI. NeoDen IN12C qhia tshwj xeeb rau cov nyiaj tau los hauv thaj chaw hauv qab no:
1. Kev saib xyuas-dawb saw hlau tsim txo cov nqi khiav lag luam
Ib txwm siv cov tshuab reflow soldering siv carbon steel chains uas yuav tsum tau siv tsis tu ncua ntawm siab -cov roj lubricating kub thiab muaj rusting thaum lub sij hawm ntev downtime. Lub IN12C ntiav cov hlau tsis muaj steel hlau mesh rail, uas yog kev saib xyuas -dawb, xeb- pov thawj, thiab hnav (<5 kg). This not only reduces daily maintenance costs but also lowers motor load, extending the equipment's lifespan.
2. Lub zog tseem ceeb- txuag tau qhov zoo
IN12C hloov cov raj cua sov nrog siab -kev ua tau zoo aluminium alloy cua sov daim hlau, muab cov thermal them nyiaj ua haujlwm siab thiab siv hluav taws xob tsawg. Lub zog ua haujlwm tsuas yog kwv yees li 2.2 kW. Kev kwv yees qhia tias kev txuag hluav taws xob ntau tshaj ib xyoos tuaj yeem them tus nqi ntawm kev yuav ib chav tsev thib ob. Rau cov neeg ua lag luam tsom mus rau cov nqi khiav lag luam, qhov no sawv cev rau qhov txiaj ntsig zoo zais.
3. High Precision thiab ruaj khov
Kev tswj qhov kub thiab txias ncav cuag ± 0.5%. Ua ke nrog qhov chaw txias txias uas muaj kev ywj pheej ntawm huab cua ncig tsim, nws zoo cais cov kev cuam tshuam sab nraud. Txawm hais tias tuav 0201 cov khoom me me lossis nyuaj BGA / QFN chips, nws ua haujlwm yooj yim.
