Taw qhia
HauvPCBsib dhos kabs, reflowqhov cub yog ib kauj ruam tseem ceeb uas txiav txim siab qhov zoo ntawm cov khoom siv hluav taws xob. Ntau tus kws ua haujlwm SMT lossis cov neeg tsim khoom siv hluav taws xob feem ntau ntsib tib lo lus nug tom qab yuav khoom: "Kuv tuaj yeem siv li cas?reflow qhov cublos xyuas kom meej qhov siab tshaj plaws soldering tawm los?
Kev ua haujlwm tsis raug cai tsis yog tsuas yog ua rau muaj qhov tsis xws luag xws li cov pob qij txha txias, cov txuas hniav, thiab tombstoning, tab sis kuj tseem tuaj yeem ua rau cov khoom siv lub neej luv. Hnub no, peb yuav muab cov lus qhia hauv - qhov tob ntawm kev ua haujlwm raws li cov yam ntxwv ntawm covNeoDen IN12C, 12-zone ntse eco-phooj ywg reflow qhov cub.
Ua ntej-Kev Npaj Pib Pib
Raws li tau hais tseg hauv Tshooj 4.2 ntawm lubNeoDen IN12C siv phau ntawv, ib puag ncig kev txhim kho kom zoo yog qhov tseem ceeb rau kev ua haujlwm ruaj khov.
1. Kev kuaj xyuas hluav taws xob thiab kev nyab xeeb
- Voltage Verification:IN12C ua haujlwm ntawm 220V ib zaug -theem AC zog. Ua ntej siv hluav taws xob, xyuas kom lub zog hluav taws xob muaj zog ruaj khov thiab cov cuab yeej siv tau zoo los tiv thaiv electrostatic puas rau cov khoom siv hluav taws xob (xws li ICs thiab sensors).
- Environmental Requirements:Cov cuab yeej yuav tsum tau muab tso rau hauv qhov dej - qhov cua, plua plav- ib puag ncig dawb, kom deb ntawm cov khoom tawg yooj yim thiab tawg. Txawm hais tias IN12C tau nruab nrog lub tshuab lim pa, qhov chaw ua haujlwm huab cua zoo yog qhov tseem ceeb rau cov neeg ua haujlwm noj qab haus huv.
2. Kev npaj khoom siv
- PCB dav sib txuam:Paub meej tias qhov dav ntawm PCBs yuav tsum ua tiav. IN12C txhawb nqa qhov siab tshaj plaws PCB dav ntawm 300 hli.
- Solder Paste Management:Xyuas kom tseeb tias cov tshuaj txhuam tau raug coj mus rau hauv chav tsev kub thiab nplawm kom huv si. Yog tias cov tshuaj pleev xim txias dhau lawm, cov khoom siv solder tuaj yeem tsim thaum lub sijhawm rov ua haujlwm.
System Startup: NeoDen IN12C's Intelligent Interaction
Lub IN12C nta lub zais tswj vaj huam sib luag tsim, uas tsis tsuas yog zoo li sleek tab sis kuj tiv thaiv lub vijtsam los ntawm kev cob qhia plua plav.
- Hwj chim On:Tig rau lub ntsiab fais fab hloov thiab tos kom lub operating system khau raj.
- Nkag mus rau Control Interface:Nkag mus rau lub ntsiab zaub mov ntawm cov zaub. Koj yuav pom tias IN12C's system teb sai heev, ua tsaug rau nws cov kev sib xyaw ua ke tswj hwm nti.
- Pib cua sov:Nias lub pob "Heat" ntawm qhov system interface. Nyob rau lub sijhawm no, sab sauv 6 thiab qis dua 6 cov khoom siv cua sov thoob plaws 12 thaj chaw kub yuav pib ua haujlwm.
Yuav ua li cas los teeb lub Perfect Soldering Temperature Curve?
1. Nkag siab txog plaub theem tseem ceeb
Raws li Tshooj 5 ntawm lubNeoDen IN12Cneeg sivphau ntawv, cov hauv qab no yuav tsum tau txiav txim siab thaum teeb tsa qhov nkhaus:
- Preheat Zone:Qhov pom zoo cua sov yog 1-3℃/ s los tiv thaiv thermal shock tawg ntawm cov khoom.
- Soak Zone:Feem ntau khaws cia ntawm 150-180℃rau 60-120 vib nas this kom ntseeg tau tias qhov kub thiab txias thoob plaws PCB thiab qhib qhov flux.
- Reflow Zone:Qhov no yog lub sijhawm thaum solder pob qij txha. Rau cov hlau lead- dawb solder paste, qhov kub siab tshaj plaws feem ntau yog teem ntawm 235-250℃.
- Cooling Zone:Kev ua kom txias sai ua rau cov hlau nplaum zoo dua, txhim kho kev sib koom ua ke.
2. Leveraging NeoDen IN12C's 12-Zone Advantage
IN12C nta 12 qhov chaw kub, txhua qhov muaj qhov kub thiab txias. Qhov no txhais tau tias koj tuaj yeem ua tiav qhov tseeb dua thiab zoo dua qhov kub thiab txias dua li cov khoom siv 8-zone.
Kev Ua Haujlwm Kub Kub: Ua tsaug rau nws qhov ntsuas kub patented - sib npaug ntawm cov cua sov phaj thiab Swiss- cov khoom cua sov tuaj, IN12C ua tiav qhov ntsuas kub qhov tseeb ntawm ± 0.5%. Thaum lub sij hawm teeb tsa, koj tuaj yeem ua kom zoo - kho qhov kub qhov sib txawv ntawm cov cheeb tsam raws li cov thickness ntawm lub rooj tsavxwm thiab cov khoom ntom ntom.
3. Siv cov ua -hauv "Smart Temperature Measurement System"
Txoj hauv kev ib txwm muaj suav nrog kev yuav khoom thib peb - tog ntsuas kub ntsuas cov cuab yeej raug nqi ntau txhiab daus las. Nrog rau IN12C, txawm li cas los xij, koj tuaj yeem siv ncaj qha rau nws ua - hauv kev ntsuas nkhaus ntse. Tsuas yog txuas lub thermocouple sensor rau PCB thiab ntsaws rau hauv lub cuab yeej interface, thiab lub kaw lus yuav npaj qhov ntsuas kub tiag tiag hauv lub sijhawm.
Tswv yim: Sib piv qhov ntsuas qhov nkhaus nrog qhov nkhaus theoretical thiab kho qhov tsis sib xws ntawm txhua qhov kub thiab txias kom txog thaum ob qho tib si sib dhos.
Mechanical Adjustments: Ua kom Smooth Conveyance
1. Qhia Rail Width Kho
Kho qhov kev ncua deb ntawm cov kev taw qhia rails siv lub handwheel raws li qhov dav ntawm PCB. Xyuas kom tseeb tias PCB tsis deform vim yog nruj heev los yog poob los ntawm kev xoob ntau dhau. IN12C's guide rail design yog robust thiab precisely, ua rau nws haum rau ntev - lub sij hawm ua hauj lwm.
2. Kev teeb tsa ceev
Teem cov saw ceev raws li qhov yuav tsum tau muaj ntawm cov khoom siv soldering. IN12C txhawb kev hloov pauv tsis hloov pauv ntawm 5 txog 60 cm / min. Feem ntau, txhawm rau kom muaj kev sib pauv cua sov txaus, qhov ceev rau me me mus rau nruab nrab - PCBs yog teem ntawm 25 thiab 45 cm / min.
Kev soj ntsuam ntau lawm: Leveraging IN12C's Eco-Cov yam ntxwv zoo
Ntau tus neeg siv pom cov tshuaj tsw qab muaj zog thaum siv cov tshuab reflow soldering. Qhov no yog tshwm sim los ntawm cov flux nyob rau hauv lub solder paste volatilizing ntawm qhov kub thiab txias thiab tso cov pa phem.
- Pab kom Built-hauv Lim:Ib qho ntawm IN12C cov yam ntxwv zoo tshaj plaws yog nws ua tau - hauv fume filtration system. Tsis muaj qhov xav tau rau lub cumbersome installation ntawm sab nraud ducts. Tsuas tshawb xyuas hauv qhov system teeb tsa tias cov kiv cua lim tau ua haujlwm, thiab cov cuab yeej yuav cia li ua kom huv huv.
- Kev Tiv Thaiv Kev Nyab Xeeb:Yog tias cov cuab yeej ua haujlwm tsis zoo lossis lub hau npog sab saum toj raug qhib, IN12C yuav cia li nres ua haujlwm thiab suab lub tswb kom ntseeg tau tias tus neeg siv khoom muaj kev nyab xeeb.

Yuav Ua Li Cas Ntxiv Lub Neej Ntawm Lub Qhov cub Reflow?
- Kev tu txhua hnub:Tom qab kev tsim khoom tiav, tos kom txog thaum lub qhov cub kub poob qis dua 100 degree, tom qab ntawd ntxuav cov khoom seem thiab plua plav los ntawm cov khoom siv.
- Lubrication tsis tu ncua:Txhua 2-4 lub lis piam ntawm kev ua haujlwm, thov siab - lubricant kub rau cov saw tsav thiab Japanese NSK bearings kom ntseeg tau tias kev xa khoom zoo.
- Filter Hloov:Cov lim hauv IN12C feem ntau kav 8 lub hlis. Yog tias koj pom qhov poob ntawm kev ua kom huv huv, nco ntsoov hloov lub lim nrog ib qho tshiab raws li cov lus qhia hauv phau ntawv qhia.
- Calibration Check:Peb pom zoo kom calibrating txhua qhov kub thiab txias hauv peb lub hlis twg siv qhov ntsuas kub kom ntseeg tau tias qhov ntsuas kub tau ntsuas qhov ntsuas kub tiag tiag.
Xaus
NeoDen IN12C yog ntau tshaj li qhov cub reflow xwb, nws yog ib qho kev daws teeb meem uas ua ke nrog patented cua sov thev naus laus zis, ntsuas qhov ntsuas kub ntse, thiab eco-kev ua kom huv huv. Nws ua kom yooj yim SMT cov txheej txheem rau hauv CNC- tswj kev ua haujlwm, tso cai rau koj tsom mus rau kev txhim kho cov khoom lag luam thiab kev ua kom tiav.
