Taw qhia
Hauv thaj tsam ntawm SMT,reflow solderingyog ib qho tseem ceeb tshaj plaws uas txiav txim siab cov khoom zoo. Txawm hais tias koj yog ib tus kws tsim khoom siv hluav taws xob tsuas yog nkag mus rau hauv kev lag luam lossis tus thawj tswj hwm SMT lub Hoobkas, kev nkag siab txog kev ua haujlwm ntawm reflow soldering tsis tsuas yog pab hauv kev xaiv cov khoom siv tab sis kuj tseem txhim kho cov txiaj ntsig ntau lawm thiab txo cov nqi rov ua haujlwm.
NeoDen yuav muab cov kev qhia tshwj xeeb ntawm lubNeoDen IN12Ccoj koj mus rau hauv - qhov tob tob ntawm txhua qhov tseem ceeb ntawm reflow soldering, qhia tias yog vim li cas lub siab -kev ua tau zoo reflow soldering tshuab yog "lub plawv thiab tus ntsuj plig" ntawm precision PCBA ntau lawm.
Lub hom phiaj tseem ceeb ntawm Reflow Soldering yog dab tsi?
Raws li lub npe txhais tau hais tias, reflow soldering yog cov txheej txheem ntawm cua sov lub PCB board nrog mounted Cheebtsam kom yaj lub solder paste ua ntej - siv rau cov ntaub qhwv, uas tom qab ntawd tsim cov tshuab thiab hluav taws xob sib txuas thaum txias.
Txawm hais tias qhov no yuav zoo li yooj yim, hauv micrometer - nplai ntiaj teb ntawm SMT, qhov tseeb ntawm kev tswj qhov kub thiab txias txiav txim siab zoo soldering. Yog tias qhov kub thiab txias dhau lawm, cov khoom yuav puas. Yog tias nws qis dhau lawm, "txias solder pob qij txha" yuav tshwm sim. Qhov no ua rau peb mus rau qhov tseem ceeb tshaj plaws kev ntsuas ntawm reflow soldering: thermal profile.
Plaub Qhov Chaw Kub Kub Tseem Ceeb ntawm Reflow Soldering
Raws li cov txheej txheem txheej txheem hauv lubNeoDen IN12C siv phau ntawv, ib tug scientifically suab soldering txheej txheem yuav tsum nruj me ntsis raws li plaub theem. Txhua theem muaj kev ua haujlwm meej hauv IN12C's 12-zone system.
1. Ua ntej-heat Zone
- Lub Hom Phiaj:Txhawm rau xyuas kom cov PCB thiab cov khoom ua kom sov ntawm tus nqi sib xws.
- NeoDen IN12C Qhov Zoo:IN12C siv aluminium alloy cua sov phaj tshuab. Hauv thaj tsam ua ntej - cua sov, cov cua kub cua tshuab ua kom cov cua sov nkag mus zoo ib yam. Qhov no tiv thaiv kev ntxhov siab vim los ntawm cov cua kub ntau dhau, yog li zam kom tsis txhob muaj micro- tawg hauv cov khoom rhiab xws li ceramic capacitors.
2. Soak Zone
- Lub hom phiaj:Txhawm rau evaporate lub flux nyob rau hauv lub solder muab tshuaj txhuam thiab tshem tawm oxidation txheej los ntawm cov ntaub qhwv thiab cov khoom ua.
- Cov ntsiab lus tseem ceeb:Thaum lub sij hawm no, nws yog ib qho tseem ceeb kom ntseeg tau tias qhov kub thiab txias thoob plaws lub rooj tsavxwm (tsis hais qhov loj me me) zoo ib yam.
- NeoDen IN12C Qhov Zoo:Nws txoj kev tsim muaj patented tsim rau cov paib cua sov ua kom txo qis qhov sib txawv ntawm qhov kub thiab txias, kom ntseeg tau tias siab -tam sim no inductors thiab cov khoom me me 0201 ntawm cov boards nyuaj ncav cuag qhov kub thiab txias ib txhij.
3. Reflow Zone
- Lub hom phiaj:Ceev nrooj nce qhov kub siab tshaj ntawm cov nplaum nplaum melting point (feem ntau ntawm 217℃thiab 250 degree) los tsim ib txheej txheej ntawm lub cev.
- Txheej txheem kev sib tw:Lub sijhawm ntawm qhov kub siab tshaj (TAL) yuav tsum yog qhov tseeb.
- NeoDen IN12C Qhov Zoo:Lub IN12C nta 12 qhov chaw kub (6 sab sauv thiab 6 qis) nruab nrog cov cua sov tuaj ntawm Switzerland. Qhov ntau- cheeb tsam tsim no tso cai rau lub steeper ramp- nce tus nqi thiab ruaj khov siab siab kub txij nkawm, yog li txo qhov "tombstone" nyhuv thaum lub sij hawm soldering txheej txheem.
4. Qhov chaw txias
- Lub Hom Phiaj:Fast solidification los tsim zoo, robust solder sib koom siv lead ua qauv.
- NeoDen IN12C Qhov Zoo:Nruab nrog 4-channel cua txias kiv cua system. Kev ua kom txias nrawm zoo tiv thaiv qhov roughness ntawm cov pob qij txha thiab txhim kho kev qaug zog.
Vim li cas thiaj xaiv NeoDen IN12C?
Thaum xaiv lub tshuab reflow soldering, pawg neeg tsim khoom thiab engineers feem ntau ntsib qhov kev sib tw ntawm kev sib npaug, qhov chaw, thiab kev xav txog ib puag ncig. NeoDen IN12C tau tsim tshwj xeeb los daws cov "kev lag luam mob cov ntsiab lus."
1. Patented Temperature-Equalizing Technology
Cov tsoos reflow soldering tshuab feem ntau siv cov teeb infrared lossis cov qauv cua sov, uas yooj yim tsim cov duab ntxoov ntxoo thermal. Lub NeoDen IN12C siv qhov ntsuas kub patented - sib npaug ntawm cov cua sov phaj, ua ke nrog lub siab - kub ceev - cua tshuab los ntawm Nyiv NSK, kom ua tiav cov thermal them nyiaj siab heev. Raws li tau piav qhia hauv Tshooj 3.3 ntawm phau ntawv qhia, qhov kev tsim qauv no ua kom ntseeg tau tias txhua nti ntawm qhov chaw cua sov tseem nyob hauv kev tswj xyuas.
2. Ua -hauv Fume Filtration System
Rau kev pib ua lag luam lossis chaw soj nstuam ua R & D hauv cov tsev ua haujlwm, fume extraction yog ib qho nyuaj heev.
- Pain Point:Cov cuab yeej siv pa yuav tsum tau teeb tsa hnyav sab nraud ducts.
- IN12C Kev daws teeb meem:Nws yog ib qho ntawm ob peb lub compact reflow soldering tshuab thoob ntiaj teb los ua kom muaj ib qho ua tau -nyob rau hauv soldering fume filtration system. Siv ntau- txheej siab - lim cartridges, nws ncaj qha purify cov pa phem tsim tawm thaum lub sij hawm soldering. Qhov no tsis tsuas yog txuag ntawm cov nqi hluav taws xob tab sis kuj ua tau raws li cov ntaub ntawv pov thawj ib puag ncig ntawm cov chaw tsim khoom niaj hnub no (CE daim ntawv pov thawj).
3. Kev Ntsuas Kub Kub Ntsuas Ntsuas
Engineers qhov kev txhawj xeeb loj tshaj plaws yog tsis paub qhov ntsuas kub hauv qhov cub.
IN12C's Core Competitive Advantage: Nws muaj qhov ua tau zoo ua - hauv qhov ntsuas kub ntsuas qhov ntsuas kub. Los ntawm kev sib koom tes sensor, koj tuaj yeem tau txais cov ntaub ntawv tiag tiag -lub sijhawm thermal los ntawm PCB nto thiab tsim cov duab nkhaus ncaj qha rau ntawm cov zaub.
Feem ntau SMT Soldering Defects thiab IN12C Solutions
Hauv qab no yog cov kev sib tw sib tw thiab lawv cov kev daws teeb meem ntawm IN12C:
| Tej yam tsis zoo | Ua rau | NeoDen IN12C Kev daws teeb meem |
| Tombstoneing | Asynchronous wetting ntawm ob qhov kawg, cua sov tsis sib xws | Kev tswj qhov kub thiab txias thoob plaws 12 thaj chaw ua kom ob sab ntawm cov ntaub qhwv mus txog qhov melting point ib txhij. |

Kev ua haujlwm thiab kev tu
Raws li Tshooj 8.3 ntawm NeoDen IN12C cov neeg siv phau ntawv, cov cuab yeej no muaj cov neeg siv siab heev - tus qauv tsim:
- Concealed screen tsim:Tsis tsuas yog nws zoo nkauj zoo nkauj, tab sis nws kuj tseem tiv thaiv cov tub ntxhais tswj tsev thaum lub sij hawm thauj mus los thiab ntau lawm.
- Yooj yim hloov lim:Cov lim dej feem ntau kav 8 lub hlis. Kev hloov yuav tsum tsuas yog Phillips- lub taub hau ntsia hlau kom tshem tawm cov vaj huam sib luag sab thiab tuaj yeem ua tiav hauv feeb.
- Tsawg- zog ua haujlwm:Lub zog siab tshaj plaws yog 4.8 kW, tab sis lub zog ua haujlwm tsuas yog kwv yees li 2.2 kW. Qhov no sawv cev rau qhov zoo dua nyiaj txiag rau cov tuam txhab hluav taws xob uas xav txo cov nqi hluav taws xob.
Xaus
Txawm hais tias lub hauv paus ntsiab lus ua haujlwm ntawm reflow soldering yog rooted nyob rau hauv lub cev thermal convection, nws cov tswv yim daim ntawv thov yog ib tug kos duab ntawm "sib npaug." Los ntawm kev npaj meej ntawm 12 thaj chaw kub, patented cua sov tshuab, thiab kev tsim kho tshiab hauv kev pom, NeoDen IN12C ua kom yooj yim cov txheej txheem soldering nyuaj rau hauv kev ua tau zoo, eco-tus phooj ywg tsim khoom.
Yog tias koj tab tom nrhiav lub conveyor -hom reflow soldering tshuab muaj peev xwm tuav tau siab -precision PCBA soldering (xws li lub xov tooj ntawm tes motherboards, cov khoom siv kho mob, thiab cov khoom siv hluav taws xob hauv tsheb), NeoDen IN12C-nrog nws qhov kub thiab txias ntawm chav tsev kub mus txog 300℃thiab compatibility nrog PCBs 0} mm yog qhov dav txog li 3 kev xaiv.
