Qhov Tseem Ceeb 1: Mark Point Recognition yuam kev
Thaum lub sij hawm tag nrho automated printing, yog tias lub koob yees duab tsis tuaj yeem "pom" cov ntsiab lus ntawm PCB, tag nrho lub tshuab yuav tuaj yeem nres. Qhov no yog ib qho ntawm cov lus yuam kev tshaj plaws ntawmnto mount kab.
1. Cov tsos mob piav qhia
Lub tshuab qhia cov lus ceeb toom xws li "Tsis pom Mark point" lossis "Kev lees paub ntau dhau offset," tiv thaiv lub conveyor los ntawm kev pub mis rau lub rooj tsavxwm lossis ua rau kev sib tw ua tsis tiav.
2. Cov kws tshaj lij kev soj ntsuam thiab kev daws teeb meem
Raws li Tshooj 3.3.2 ntawm lubNPE 450neeg sivphau ntawv(Kho Parameter Chaw), kev lees paub tsis ua haujlwm feem ntau tsis tshwm sim los ntawm lub koob yees duab kho vajtse puas tsuaj, tab sis los ntawm cov teeb meem nrog ib puag ncig thiab algorithm compatibility:
- Flexible tswj ntawm 6 lub teeb qhov chaw:Cov ntaub ntawv PCB sib txawv (xws li matte dub solder daim npog qhov ncauj, zoo li kub plating, lossis tooj liab nrog oxide txheej) muaj qhov sib txawv loj heev. Yog tias kev lees paub ua tsis tiav, ua ntej kho lub teeb ci ci hauv qhov software interface. Cov neeg siv phau ntawv qhia pom zoo: Rau cov ntaub ntawv muaj txiaj ntsig zoo, tsim nyog txo lub teeb siv kom tsis txhob "overexposure" uas ua rau qhov muag plooj Mark taw qhia.
- Kev ntxuav lub cev ntawm ob lub koob yees duab lo ntsiab muag:CovNPE 450solder paste tshuab luam ntawvntiav -precision dual- lub koob yees duab system (sab saum toj thiab hauv qab). Residual flux los yog hmoov av tuaj yeem tsim "dawb haze" uas ua rau lub ntsej muag tsis pom. Cov kws tshaj lij pom zoo ua qhov kho qhov muag- qib tu txhua hnub siv lint-dawb daim ntawv dipped hauv ib qho me me ntawm cov cawv tsis muaj dej, ua raws li cov lus qhia ntawm nplooj 27 ntawm phau ntawv siv.
- Tshawb nrhiav thaj chaw thiab cov ntsiab lus cuam tshuam:Yog tias muaj cov ntawv luam tawm zoo sib xws lossis cov ntaub qhwv ib ncig ntawm lub cim taw tes, lub koob yees duab yuav ntsib "tsis meej pem." Nyob rau hauv cov ntaub ntawv no, koj yuav tsum rov- xauv lub cim taw tes nyob rau hauv lub "Kho kom raug ntaub ntawv - Kho" interface thiab manually nruj lub thawv tshawb xyuas kom ntseeg tau tias tsuas yog ib tug feature taw tes nyob rau hauv lub teb ntawm saib.
Qhov Tseem Ceeb 2: Tsis tiav Solder Paste Squeegeeing lossis Printing Defects
Cov residue ntawm lub stencil nto tom qab luam ntawv, los yog tsis txaus solder muab tshuaj txhuam rau ntawm lub ncoo, yuav ncaj qha ua rau txias pob qij txha los yog tsis txaus solder tom qab reflow.
1. Nqe lus piav txog qhov teeb meem
Tom qab luam ntawv, solder paste tseem nyob rau hauv stencil apertures, thiab solder paste rau ntawm PCB pads tsis yog tag nrho tsim, nrog qhov muag plooj npoo.
2. Cov kws tshaj lij kev soj ntsuam thiab kev daws teeb meem
Rau ND450 lub tshuab hluav taws xob tswj huab cua-float squeegee system, kev daws teeb meem yuav tsum hais txog ob qho "force" thiab "txoj hauj lwm":
- Qhib "Pressure Adjustment" ntawm lub ntsiab interface:Tom qab teeb tsa tus nqi squeegee siab nyob rau hauv "Printing Parameter Settings," koj yuav tsum rov qab mus rau lub ntsiab interface thiab nyem rau ntawm [Pressure Adjustment] khawm rau lub tshuab hluav taws xob tswj kom xa cov lus txib mus rau lub tog raj kheej squeegee.
- Kev ruaj ntseg ntawm PCB Support (Thimble Placement):Yog hais tias PCB sags me ntsis nyob rau hauv siab thaum luam ntawv (mos board tshwm sim), lub squeegee yuav siv tsis tau lub zog sib npaug. Xa mus rau ntu "Kev daws teeb meem" ntawm phau ntawv qhia thiab xyuas kom meej tias cov thimbles hauv qab (cov pins txhawb nqa) yog qhov chaw ruaj ntseg thiab tsis cuam tshuam nrog cov khoom ntawm PCB. Lub tiaj tus npoo yog qhov tseem ceeb rau 0.01mm precision printing.
- Squeegee Cylinder Rebound Test:Xyuas seb lub squeegee lub tog raj kheej ua haujlwm li cas. Yog hais tias lub tog raj kheej muaj cov pa tawm los yog lag, nws yuav ua rau tsis txaus los yog tsis sib npaug ntawm lub squeegee.
Qhov teeb meem tseem ceeb 3: Kev luam ntawv offset thiab misalignment
Offset yog "arch-tus yeeb ncuab" ntawm SMT ntau lawm, tshwj xeeb tshaj yog thaum luam tawm 0201 lossis 0.4mm pitch Cheebtsam, qhov twg txawm tias qhov sib txawv ntawm 0.05mm tuaj yeem ua rau muaj kev sib txuas ntau.
1. Kev piav qhia ntawm Phenomenon
Lub tshuab luam ntawv luam tawm txoj haujlwm tsis sib haum nrog qhov nruab nrab ntawm PCB ncoo, nthuav tawm qhov tsis tu ncua lossis tsis hloov pauv.
2. Cov kws tshaj lij kev soj ntsuam thiab cov neeg siv phau ntawv daws teeb meem
ND450 nta lub siab -cov lus qhia qhov tseeb sib nqus ntsuas qhov ntsuas, uas muaj qhov theoretically muaj qhov rov ua tau zoo heev. Yog tias offset tshwm sim, nws feem ntau tshwm sim los ntawm kev cuam tshuam lub cev nrog lub tshuab tawm tswv yim:
- Tshawb xyuas 3-axis adjustment platform:X / Y / Theta axes ntawm lub tshuab luam ntawv muab tshuaj txhuam cia siab rau cov ntsia hlau lead. Yog tias qhuav- cov tshuaj nplaum los yog hmoov av sib sau ua ke ntawm cov hlau lead, nws tuaj yeem ua rau lub ntsej muag tshem tawm cov txheej txheem ua tsis tiav. Tshooj 5.2.2 ntawm phau ntawv qhia pom zoo kom ntxuav cov lus qhia thiab cov ntsia hlau lead thiab siv lub teeb roj nplua nyeem txhua hli.
- Kaw-loop calibration logic:Txheeb xyuas seb qhov ntsuas ntsuas qhov ntsuas qhov ntsuas qhov ntsuas puas tau qhia txog qhov yuam kev. ND450 saib xyuas lub platform txoj haujlwm hauv lub sijhawm; Yog tias pom lub cev tiv thaiv ntau dhau, lub software yuav ua rau lub tswb.
- Stencil Clamping xwm txheej:Xyuas seb tus ncej stencil puas ruaj ntseg xauv. Yog tias cov stencil muaj kev cuam tshuam me ntsis thaum lub sijhawm luam ntawv, tsis muaj software them nyiaj yuav zoo.
Teeb meem tseem ceeb 4: Cov teeb meem nkag ntawm lub rooj tsavxwm thiab cov khoom tsis raug
Jams thaum lub sij hawm board nkag mus ncaj qha mus cuam tshuam lub atherosclerosis ntawm tag nrho cov SMT ntau lawm kab.
1. Cov tsos mob piav qhia
Lub PCB tau daig los yog qaij nyob rau hauv lub conveyor, los yog lub sensor tsis pom tias PCB nyob rau hauv txoj hauj lwm.
2. Cov kws tshaj lij kev soj ntsuam thiab kev daws teeb meem
Xa mus rau Tshooj 3.3.1 (Board Entry Parameter Editing) ntawmNPE 450neeg sivphau ntawv:
- Dynamic hloov ntawm rail dav:Tuav ib sab clearance ntawm 0.5 hli mus rau 1.0 hli nruab nrab ntawm lub rooj tsavxwm thiab lub tsheb ciav hlau. Yog tias qhov haum nruj dhau, nws yuav ua rau lub rooj tsavxwm deformation lossis lub cev muaj zog nres. Yog tias xoob dhau lawm, nws yuav ua rau PCB skew thaum thauj khoom.
- Sensor Sensitivity Check:Yog hais tias lub infrared sensors nyob rau hauv lub tshuab luam ntawv yog them los ntawm solder paste splatter, lub tswb cuav yuav tshwm sim. Lub sensor probes yuav tsum tau so tsis tu ncua los xyuas kom meej lub teeb liab tshwm sim.
- Board Feed Speed Settings:Rau qhov hnyav, tuab cov laug cam, nws raug nquahu kom tsim nyog txo cov kev tsheb ciav hlau ceev hauv "Kho kom raug cov ntaub ntawv - Board Feed" interface los txhim kho kev ruaj ntseg.
