Yuav Siv Lub Qhov Cub Li Cas: Ib Daim Ntawv Qhia SMT Soldering Qhia Los Ntawm Kev Teeb Kom Zoo - Xov Xwm

HauvSMT ntau lawm txheej txheem, covreflow qhov cubyog undoubtedly lub ntsiab tseem ceeb txiav txim qhov kev cia siab ntawm cov khoom kawg. Ntau lub tuam txhab hluav taws xob feem ntau poob rau hauv kev xav tsis zoo tias qhov cub reflow tsuas yog "chamber cua sov" thiab ntev npaum li qhov kub siab txaus, cov khoom siv yuav ua kom zoo. Txawm li cas los xij, qhov no tsis yog li ntawd. Reflow soldering tsis yog tsuas yog cua sov xwb, nws yog ib qho kev kos duab ntawm cov txheej txheem tswj.

Kab lus no yuav muab cov kev qhia tshwj xeeb ntawm covNeoDen IN12C reflow qhov cublos muab koj nrog SMT cov lus qhia dav dav, npog txhua yam los ntawm kev teeb tsa yooj yim rau kev ua kom zoo, los pab koj daws qhov teeb meem soldering thiab txhim kho cov khoom tsim tawm.

Soldering Defects Ua los ntawm Temperature Inhomogeneity:Cov cuab yeej siv niaj hnub feem ntau muaj ob peb thaj chaw kub lossis ib qho kev tsim cua kub tsis zoo, ua rau muaj qhov kub thiab txias hloov pauv thoob plaws PCB nto. Qhov no tuaj yeem ua rau tsis ua tiav rov qab los yog cov khoom puas tsuaj vim yog overheating, tshwj xeeb tshaj yog rau cov chips nyuaj xws li BGAs thiab QFNs, qhov twg txawm me me sib txawv hauv qhov kub thiab txias tuaj yeem ua rau cov pob qij txha txias.
Odors thiab Environmental Pollution:Kev ua haujlwm sab hauv tsev feem ntau tsis muaj txiaj ntsig fume extraction systems. Cov pa phem tso tawm los ntawm flux volatilization tsis tsuas yog ua rau lub chaw ua haujlwm tsis zoo xwb tab sis kuj ua rau muaj kev phom sij rau cov neeg ua haujlwm noj qab haus huv. Ntau tus neeg siv tshawb nrhiav "yuav ua li cas nrog cov ntxhiab tsw muaj zog los ntawm kev rov ua dua," tab sis lub hauv paus ua rau muaj tseeb nyob rau hauv cov khoom tsis muaj ib qho ua tau - hauv kev pom.
Nyuaj hauv Curve Configuration:Kev tswj tsis raug ntawm qhov tsis raug rau preheating, tas li -kub, reflow, thiab txias theem. Qhov tsis muaj tiag tiag - lub sijhawm saib xyuas yuam cov neeg ua haujlwm hloov kho raws li kev paub dhau los, ua rau muaj kev sim siab siab - thiab - cov nqi yuam kev thiab cov khoom pov tseg tseem ceeb.

Txhawm rau daws cov laj thawj ntawm cov teeb meem no, NeoDen IN12C muab cov txheej txheem kev daws teeb meem rau kev tsim khoom siv hluav taws xob los ntawm kev siv tshuab thev naus laus zis thiab kev tswj hwm ntse.

Raws li tus neeg siv phau ntawv NeoDen IN12C, peb tau teev cov SOP rau koj.

Kev nyab xeeb yog qhov yuav tsum tau ua ua ntej rau kev tsim khoom. Thaum txuas cov khoom siv hluav taws xob, xyuas kom qhov hluav taws xob ua tau raws li 220V ib zaug -theem yuav tsum tau thiab xyuas kom muaj av zoo (E-xov) kom tsis txhob muaj hluav taws xob zoo li qub los ntawm kev puas tsuaj rau cov khoom rhiab. Lub NeoDen IN12C tau nruab nrog peb lub cim - xim xwm txheej: ntsuab qhia tias txhua thaj chaw kub tau mus txog lawv cov nqi teev, daj flashing qhia tias cua sov ua haujlwm, thiab liab qhia tias muaj kev ua txhaum lossis kaw. Ua ntej pib ua haujlwm, xyuas kom paub tseeb tias lub teeb pom kev ua tau zoo hauv cov pa luam yeeb tau teeb tsa kom ntseeg tau tias muaj ntxhiab tsw - thaj chaw ua haujlwm dawb uas ua tau raws li cov qauv ib puag ncig.

Kev thauj mus los ntawm PCB du yog qhov tseem ceeb. IN12C nta lub teeb yuag qhia kev tsheb ciav hlau tsim (qhov hnyav<5 kg), effectively reducing motor load and transport vibration. Adjust the conveyor track according to the PCB dimensions. It is generally recommended that the track width be approximately 1 mm wider than the PCB width to ensure the board passes smoothly through the soldering zone.

Txoj siv conveyor siv ceev ncaj qha cuam tshuam rau lub sijhawm soldering. Nws yog feem ntau pom zoo kom teem lub ceev ntawm 250-300 mm / min. Txawm li cas los xij, nco ntsoov tias kev hloov ntawm cov saw nrawm yuav cuam tshuam rau qhov kub thiab txias. Yog li ntawd, qhov kub thiab txias nkhaus yuav tsum tau rov kuaj dua tom qab kev hloov kho.

NeoDen IN12C nta 12 thaj chaw kub (6 sab sauv / 6 qis) nrog kev tswj hwm qhov kub thiab txias. Tom qab qhib qhov ntsuas kub, tos rau txhua cheeb tsam kom ncav cuag nws qhov chaw. Piv nrog rau cov pa roj carbon steel raj cua sov, IN12C siv siab - ua tau zoo aluminium alloy cua sov daim hlau, uas muab cov thermal them nyiaj ua haujlwm siab thiab txo qis qhov kub thiab txias. Qhov kev ywj pheej cheeb tsam tsim no ua rau cov cuab yeej teb sai sai rau kev hloov pauv kub, kom ntseeg tau tias qhov sib xws ntawm qhov kub thiab txias hauv qhov cub.

Qhov kub profile yog lub plawv ntawm reflow soldering. Qhov zoo tshaj qhov kub thiab txias profile yog ib qho tseem ceeb tshaj plaws hauv kev ua kom tau zoo - cov pob qij txha zoo.

Raws li cov hauv paus ntsiab lus ntawm reflow soldering, tus qauv kub profile muaj plaub theem:

Ua ntej- cua sov Cheeb Tsam: PCB yog cua sov los ntawm chav tsev kub, nrog cov cua kub tswj ntawm ib ncig ntawm 1℃/ s los tiv thaiv cov khoom puas los ntawm thermal shock.
Soak / Kev Ua Haujlwm Thaj Chaw: Qhov ntsuas kub feem ntau yog nyob nruab nrab ntawm 120-150℃kom ntseeg tau tias cov cua sov tsis sib xws ntawm PCB thiab cov khoom siv, qhib cov flux, thiab tso cai rau cov kuab tshuaj kom evaporate.
Reflow Zone: Qhov kub nce mus rau qhov siab tshaj plaws (feem ntau yog 20-40℃siab tshaj qhov solder paste melting point. Piv txwv li, Sn63 / Pb37 muaj qhov melting point ntawm 183 degree, yog li lub ncov yog teem rau 205-230 degree), ua rau lub solder yaj thiab tsim ib txheej hlau.
Cooling Zone: Kev ua kom txias sai sai ua rau cov pob qij txha. Qhov zoo tshaj plaws txias nkhaus yuav tsum yog daim iav duab ntawm lub reflow nkhaus kom ntseeg tau ib tug ntom crystalline qauv nyob rau hauv lub solder pob qij txha.

Lub NeoDen IN12C tau nruab nrog qhov ntsuas kub ntsuas qhov ntsuas qhov ntsuas kub. Cov neeg siv tsuas yog yuav tsum tau txuas hom K thermocouple sensor, ruaj ntseg rau qhov tseem ceeb ntawm kev sib koom ua ke ntawm PCB, muab lub rooj tsavxwm rau hauv qhov cub, thiab nyem "Pib" los tsim kom muaj qhov tseeb -lub sijhawm ntsuas kub. Sib piv qhov ntsuas qhov nkhaus nrog qhov nkhaus pom zoo los ntawm tus neeg muab tshuaj txhuam. Yog tias cov duab tsis sib xws, zoo -kho qhov kub thiab txias hauv txhua cheeb tsam (kev pom zoo hloov ntawm kwv yees li 5℃ib kauj ruam) los yog lub conveyor ceev kom txog thaum lawv sib haum.

PCBs uas muaj peev xwm thermal sib txawv xav tau cov txheej txheem sib txawv. Rau multilayer boards los yog boards nrog loj tooj liab cheeb tsam, uas absorbs ntau dua kub, lub teeb kub yuav tsum kuj siab dua. Whereas rau ib leeg - ib sab los yog hloov tau yooj yim, qhov kub thiab txias yuav tsum tau txo kom tsis txhob muaj kev sib tsoo. IN12C txhawb nqa kev khaws cia ntawm 40 cov ntaub ntawv ua haujlwm, tso cai rau cov neeg siv ceev nrooj thauj cov zaub mov txawv rau cov khoom sib txawv thiab ua tiav cov khoom siv tau yooj yim.

Kev saib xyuas cov cuab yeej tsis yog tsuas yog kev saib xyuas xwb tab sis kuj hais txog kev ua kom muaj txiaj ntsig zoo.

Fume Filter Maintenance: IN12C nta ib qho ua tau - nyob rau hauv flux fume filtration system, thiab lim cartridge yuav tsum tau hloov ib ntus. Raws li kev siv ntau zaus, peb pom zoo kom hloov cov fume lim txhua 8 lub hlis. Lub lim lim tuaj yeem ua rau cov cua kub tsis zoo, ua rau qhov tsis sib xws ntawm qhov kub thiab txias.
Chamber Cleaning: Tsis tu ncua tshem tawm cov flux condensation ntawm sab hauv. Yog tias cov kua dej ntws mus rau hauv PCB, nws yuav ua rau luv luv. Thaum ntxuav, nco ntsoov xyuas lub hau npog sab saum toj nrog lub pas nrig txhawb nqa thiab ua raws li cov txheej txheem kev nyab xeeb hauv chav kuaj.
Chain Maintenance: Ua tsaug rau nws cov stainless hlau mesh saw tsim, NeoDen IN12C ua haujlwm txij nkawm-dawb, tshem tawm qhov xav tau ntau zaus -kub roj nplua nyeem cov ntawv thov los ntawm cov tsoos carbon steel chains, yog li txo tus nqi ntawm kev poob qis.
