Wave soldering tshuabkom ua tiav cov txiaj ntsig zoo welding, ua ntej vuam yuav tsum yog cov khoom siv debugging, cov hauv qab no los qhia cov txheej txheem yoj vuam txheej txheem debugging.
I. Lub tshuab yoj soldering taug qab qib debugging
Yog tias txoj kev khiav tsis sib luag rau kev ua haujlwm, tag nrho cov txheej txheem ntawm cov khoom siv sib kis tau nruab rau hauv lub xeev tilted. Tag nrho cov txheej txheem ntawm kev ua haujlwm yog tilted, tom qab ntawd vim qhov tsis sib xws ntawm txhua qhov chaw, yuav ua rau lub zog ntawm qhov chaw ntawm kev sib txhuam loj dua, uas ua rau kev thauj mus los ntawm jitter, thiab tej zaum yuav ua rau cov ncej sib kis vim yog lub zog loj heev. loj thiab tawg. Ntawm qhov tod tes, vim tias lub tank tin yuav tsum nyob rau hauv kab rov tav kom ntseeg tau tias qib ntawm nthwv dej ua ntej thiab tom qab qib, uas yuav ua rau PCB hauv nthwv dej ntawm sab laug thiab sab xis noj tin qhov siab tsis sib xws. Kauj ruam rov qab txawm tias txoj kev taug qab tuaj yeem tig los ua qhov siab ntawm nthwv dej ua ntej thiab tom qab taug kev kom phim qhov siab, tab sis lub tin tank yuav tshwm sim ua ntej thiab tom qab qhov kawg ntawm qhov siab tsis sib xws, kom cov tin nthwv dej hauv qhov ntws tawm ntawm lub nozzle tom qab kev cuam tshuam ntawm lub ntiajteb txawj nqus yuav nyob rau hauv lub nto ntawm yoj ntawm tin cross-flow. Kev thauj mus los jitter, nthwv dej tsis ruaj khov yog lub hauv paus ua rau tsis zoo vuam.
II. Wave soldering tshuab qib debugging
Cov theem ntawm lub tshuab yog lub hauv paus ntawm kev ua haujlwm ib txwm ntawm lub tshuab, lub tshuab ua ntej thiab tom qab theem ntawm kev txiav txim ncaj qha ntawm theem ntawm txoj kev khiav, txawm hais tias txoj kev taug kev tuaj yeem hloov kho los ntawm kev kho cov kab nrib ntsia hlau khib leveling khiav, tab sis tej zaum yuav ua rau lub kaum sab xis kho cov ntsia hlau vim yog lub hauv ntej thiab nraub qaum kawg ntawm lub zog tsis sib xws thiab ua rau txoj kev nqa thiab txo qis yog tsis synchronized. Nyob rau hauv rooj plaub no, kho lub kaum sab xis, thaum kawg ua rau lub PCB board immersion tin qhov siab inconsistency thiab tsis zoo vuam.
III. Lub yoj soldering tshuab tank qib debugging
Cov qib ntawm cov tin tank ncaj qha cuam tshuam qhov siab ntawm nthwv dej ua ntej thiab tom qab nthwv dej, qhov kawg ntawm nthwv dej yog siab, qhov siab kawg ntawm nthwv dej qis dua, tab sis kuj hloov qhov ntws ntawm tin yoj. Rail theem, lub cev theem, tin tank theem ntawm peb yog tag nrho, qhov tsis ua hauj lwm ntawm ib qho txuas yuav cuam tshuam rau lwm qhov txuas ob, thiab thaum kawg yuav cuam tshuam qhov zoo ntawm tag nrho lub cub tawg soldering board. Rau qee qhov kev tsim PCB yooj yim, qhov cuam tshuam ntawm cov xwm txheej saum toj no yuav tsis yog qhov tseem ceeb, tab sis rau kev tsim ntawm PCB complex, ib qho ntawm cov kev sib txuas me me yuav cuam tshuam rau tag nrho cov txheej txheem tsim khoom.
IV. Wave soldering tshuab flux spray debugging
Flux nws yog tsim los ntawm volatile organic compounds (Volatile Organic Compounds), yooj yim rau volatilize, yooj yim los tsim cov pa luam yeeb hauv vuam VOC2, thiab txhawb kev tsim cov ozone rau ntawm qhov chaw, ua ib qho chaw ntawm cov pa phem ntawm qhov chaw. 1, lub luag haujlwm: a. Txhawm rau kom tau txais cov hlau tsis muaj xeb, ua kom lub ntsej muag ntawm lub ntsej muag ntawm lub xeev huv; b. Qhov sib npaug ntawm qhov nro saum npoo exerts ib qho kev cuam tshuam ntawm lub kaum sab xis kom txo tau. Txhawb nqa solder diffusion; c. Pab cov cua sov conduction, ntub cov hlau nto yuav tsum tau soldered. 2, tyf:a. Hom Rosin; rosin acid ua ib lub hauv paus. b. Hom tsis huv; Cov ntsiab lus ntawm tsis ntau tshaj 5%, halogen-dawb, flux extension yuav tsum ntau dua 80%, tsis huv flux yog feem ntau halogen-dawb activator, yog li nws cov kev ua ub no kuj tsis muaj zog. Lub sij hawm tsis huv ntawm lub tshuab ua kom sov yog ntev dua, qhov kub thiab txias yuav tsum siab dua, uas yog qhov tsim nyog rau PCB rau hauv cov yoj yoj ua ntej lub activator tuaj yeem ua tiav. c. Dej-soluble; tivthaiv solubility nyob rau hauv dej, active, zoo fluxing kev ua tau zoo, tom qab soldering residues yog soluble nyob rau hauv dej. d. Dej-soluble; tivthaiv solubility nyob rau hauv dej, active, zoo flux kev ua tau zoo, tom qab soldering residues yog soluble nyob rau hauv dej. e. Wave soldering qhia dav, qhov dav ntawm yoj soldering qhia yuav tsum siab tshaj 5%.
V. Wave soldering tshuab qhia dav debugging
Wave soldering rail dav rail dav tuaj yeem cuam tshuam qhov zoo ntawm vuam mus rau qee yam. Thaum txoj kev tsheb ciav hlau nqaim, nws yuav ua rau PCB board downward concave, ua rau tag nrho cov PCB rau hauv nthwv dej thaum ob sab ntawm cov tin noj tsawg tin noj ntau nyob rau hauv nruab nrab, yooj yim ua rau IC lossis kab ntawm txuas hniav tsim los ntawm qhov hnyav ntawm PCB pawg thawj coj saib yuav raug mob los yog ua rau lub ntug ntawm cov saw claw taug kev jitter. Yog tias qhov ntsuas dav dav, qhov flux yuav ua rau PCB board fluttering, ua rau cov PCB pawg thawj coj sib tsoo thiab tsis zoo (tshwj tsis yog AI plug-in). Ntawm qhov tod tes, thaum lub PCB los ntawm lub crest, vim lub PCB nyob rau hauv ib tug so, lub yoj tsim los ntawm lub buoyancy ntawm lub PCB yuav ua rau lub PCB nyob rau hauv lub saum npoo ntawm crest floating, thaum lub PCB tawm ntawm lub crest. , cov khoom saum npoo yuav raug rau sab nraud quab yuam tsim los ntawm de-tinning ntawm qhov tsis zoo, uas ua rau cov khoom tsis zoo. Nyob rau hauv ib txwm muaj xwm txheej, peb clamp lub saw claw tom qab lub rooj tsavxwm PCB, lub rooj tsavxwm PCB tuaj yeem raug thawb rov qab los ntawm tes thiab tsis muaj sab laug thiab sab xis tuav lub xeev raws li qhov ntsuas.
VI. Wave soldering tshuab kev thauj mus los ceev debugging
Wave soldering kev thauj mus los ceev feem ntau, peb hais tias kev thauj mus los ceev ntawm 0-2M / min adjustable, tab sis coj mus rau hauv tus account lub wetting yam ntxwv ntawm lub Cheebtsam, raws li zoo raws li lub smoothness ntawm solder pob qij txha ntawm lub tin, qhov ceev yog tsis yog qhov nrawm dua lossis qeeb qhov zoo tshaj plaws. Txhua hom substrate muaj qhov zoo tshaj plaws soldering tej yam kev mob: tsim nyog qhov kub thiab txias ua kom zoo ntawm tus nqi ntawm flux, lub ncov ntawm qhov tsim nyog wetting thiab ruaj khov desoldering xeev, thiaj li yuav tau zoo soldering zoo. (Kev nrawm dhau los yog qeeb qeeb yuav ua rau kev sib txuas thiab kev ua haujlwm tsis raug.)
VII. Wave soldering tshuab preheating kub debugging
Wave soldering preheating kub yog cov txheej txheem vuam nyob rau hauv lub preheating tej yam kev mob yog ib tug prerequisite rau zoo los yog phem vuam zoo. Thaum lub flux yog uniformly coated rau lub PCB board, koj yuav tsum tau muab qhov tsim nyog kub los txhawb cov kev ua ntawm flux, cov txheej txheem no yuav tsum tau paub nyob rau hauv lub preheating cheeb tsam. Leaded soldering preheating kub yog khaws cia ntawm li 70-90 degree nruab nrab ntawm, thiab tsis muaj cov hmoov lead-dawb flux yam tsis tau ntxuav vim tsis muaj kev ua si yuav tsum tau nyob rau hauv siab kub thiaj li yuav qhib qhov kev ua si, yog li nws ua kom kub yog khaws cia ntawm txog 150. degree. Txhawm rau kom ntseeg tau tias qhov kub thiab txias tuaj yeem ua tau raws li cov kev xav tau saum toj no thiab tswj hwm qhov ntsuas kub ntawm qhov ntsuas kub (2 degree / hauv), cov txheej txheem nyob rau hauv lub sijhawm kwv yees li 1 feeb thiab ib nrab. Yog tias ntau tshaj qhov txwv, tej zaum yuav ua rau qhov ua kom flux tsis txaus lossis coking inactivity tshwm sim los ntawm kev tsis zoo soldering, ua rau bridging lossis virtual soldering. Ntawm qhov tod tes, thaum PCB los ntawm qhov kub thiab txias mus rau qhov kub siab yog qhov kub ceev heev yuav ua rau PCB board deformation thiab dabtsi yog khoov, preheating cheeb tsam ntawm qeeb cua sov ntawm PCB vim qhov kub ceev ntawm PCB tsim los ntawm kev ntxhov siab. tshwm sim los ntawm PCB deformation tuaj yeem raug zam kom tsis txhob cuam tshuam rau cov cim tsis zoo.
