SMT Equipment Maintenance Manual: 5 Txoj Haujlwm Saib Xyuas Txhua Hnub Rau NeoDen ND450 - Xov Xwm

Raws li thawj kauj ruam hauv lubSMT ntau lawm kab, qhov zoo ntawm solder paste luam ntawv ncaj qha txiav txim siab cov txiaj ntsig ntawm tag nrho cov kab -cov ntaub ntawv qhia tau tias ntau dua 60% ntawm cov khoom tsis xws luag yog los ntawm cov txheej txheem luam ntawv.

CovNeoDen ND450 tag nrho tsis siv neeg solder paste tshuab luam ntawvtau tsim los muab kev lag luam nrog lub compact, tag nrho -featured, thiab tus nqi siab heev- siv lub tshuab ua haujlwm zoo. Txawm li cas los xij, txawm tias qhov tseeb tshaj plaws sib nqus encoders thiab peb -axis hloov kho platforms yuav plam lawv qhov zoo tshaj plaws nyob rau lub sijhawm yam tsis muaj kev saib xyuas txhua hnub.

Phau ntawv no, nrog rau tus nomNPE 450neeg sivphau ntawv, yuav qhia koj txog tsib txoj haujlwm tseem ceeb niaj hnub tshuaj xyuas. Txawm hais tias koj yog ib tus kws tsim khoom siv hluav taws xob hauv kev lag luam pib lossis tus thawj tswj kev muag khoom siv zog ua kom muaj txiaj ntsig zoo tshaj plaws, cov lus pom zoo no yuav pab ua kom koj cov cuab yeej tswj hwm kev luam ntawv zoo.

Peb yuav tsum tau qhia meej txog lub ntsiab lus tseem ceeb: Kev Tiv Thaiv Kev Tiv Thaiv.

Kev saib xyuas ib txwm ua raws li "tawg-nws- thiab- kho- nws" txoj hauv kev, uas los ntawm tus nqi siab heev hauv kev tsim SMT niaj hnub no. Ib qho cim taw qhia kev paub tsis ua tiav tuaj yeem ua rau tag nrho cov khoom ntawm PCBs raug muab pov tseg, thaum lub tog raj kheej hnav tuaj yeem ua rau bridging lossis tsis luam tawm.

NeoDen ND450 suav nrog qhov siab -magnetic scale thiab lub tshuab hluav taws xob tswj squeegee nrog 0.01mm daws teeb meem. Cov khoom muaj txiaj ntsig siab - cov khoom muaj nqis no muaj kev cuam tshuam rau ib puag ncig plua plav thiab roj seem. Ua raws li kev soj ntsuam txhua hnub tsis tsuas yog txhim kho SMT luam ntawv raug, tab sis kuj tseem ua rau cov khoom siv lub neej kev pab cuam thiab txo TCO.

Lub ND450 ntiav ob - lub koob yees duab system (sab saum toj thiab hauv qab), uas yog lub hauv paus rau kev ua tiav kev sib dhos tsis siv neeg. Yog hais tias lub koob yees duab lo ntsiab muag muaj paug nrog solder paste splatter los yog plua plav, lub kaw lus yuav tsis tuaj yeem txheeb xyuas cov ntsiab lus kom raug, ua rau muaj kev ua yuam kev ntau zaus lossis luam ntawv tsis zoo.

Txheeb xyuas qhov xwm txheej ntawm 6 qhov chaw teeb pom kev zoo:Saib seb lub teeb LED nyob ib ncig ntawm lub koob yees duab yog qhov kaj thiab tsis sib xws. Dim teeb pom kev ncaj qha cuam tshuam rau kev paub qhov sib txawv.
Lens Ntxuav:Raws li xav tau nyob rau nplooj 27 ntawm lubneeg sivphau ntawv, siv lint -dawb daim ntaub dampened nrog ib tug me me ntawm anhydrous cawv los so lub lens.
Parameter Verification:Nkag mus rau "Hloov cov ntaub ntawv" interface hauv software thiab tshawb xyuas Mark Point Search Area settings. Yog tias muaj cov ntsiab lus cuam tshuam hauv keeb kwm yav dhau, rov- xauv cov yam ntxwv.

ND450 yog nruab nrog cov kws tshaj lij hluav taws xob tswj huab cua- lub taub hau squeegee. Qhov sib xws ntawm solder paste thickness yog nyob ntawm qhov ruaj khov squeegee siab. Yog tias lub siab squeegee tau teeb tsa tsis raug lossis lub squeegee hniav yog deformed, cov teeb meem xws li "kev tso tawm tsis zoo" lossis "tsis tiav solder paste tshem tawm" yuav tshwm sim.

Squeegee Pressure Check:Saib xyuas tus nqi hloov siab ntawm lub ntsiab interface. ND450 muaj 0.01 hli- qib nce ntxiv kom ntseeg tau tias muaj kev sib faib siab thaum luam ntawv.
Cylinder Rebound Test:Manually jog lub squeegee nce thiab nqis los saib seb lub squeegee lub tog raj kheej txav tau yooj yim thiab tsis muaj kev lag luam.
Blade Wear Inspection:Xyuas cov npoo ntawm stainless hlau squeegee hniav rau lub cev tsis muaj zog lossis khoov.

ND450 txhawb nqa peb hom kev tu: qhuav, ntub, thiab nqus. Qhov no yog qhov kev tiv thaiv zoo tshaj plaws tiv thaiv "bridging" hauv SMT ntau lawm. Yog tias daim ntawv ntxuav tsis pub noj zoo los yog lub zog ntawm lub twj tso kua mis cawv tsis txaus, cov khoom siv tshuaj txhuam hniav nyob rau hauv qab ntawm cov stencil yuav kis tau sai sai rau PCB tom ntej.

Cleaning ntawv muab:Xyuas kom muaj cov ntaub ntawv tu kom txaus los tiv thaiv lub voj voog uas tsis huv los ntawm kev khiav tawm ntawm daim ntawv.
Alcohol spray uniformity:Tshawb xyuas cov kab hnyav rau cov pa npuas lossis cov blockages. ND450 yog tsav los ntawm lub siab -torque iav lub cev muaj zog, mloog kom ua haujlwm zoo.
Vacuum Suction Verification:Saib xyuas seb lub hauv qab ntawm cov hlau mesh puas qhuav tom qab ntxuav. Yog tias nws ntub, xyuas seb lub tshuab nqus tsev lim puas xav tau kev ntxuav.

Raws li cov khoom siv mechatronic precision, ntau ntawm ND450 cov haujlwm (xws li PCB clamping thiab squeegee downward pressure) cia siab rau lub tshuab pneumatic. Kev hloov pauv huab cua yog qhov ua rau tsis muaj kev luam ntawv.

Main Air Pressure Gauge Reading:Xyuas kom tseeb tias lub inlet cua siab ruaj khov nyob rau hauv cov khoom yuav tsum tau ntau yam (0.6-0.7 MPa).
Kev soj ntsuam kev sib txuas ntawm huab cua:Mloog rau cov suab nrov nrov (qhia cov pa tawm). Tsom ntsoov rau kev tshuaj xyuas lub tog raj kheej sib txuas thiab cov khoom siv kho cua hauv huab cua hais hauv phau ntawv.
Condensate dej:Tshawb xyuas cov lim dej kom tsis txhob ya raws los ntawm kev nkag mus rau lub solenoid valve thiab ua rau muaj kev puas tsuaj.

ND450's rail dav hloov kho thiab PCB clamping system ua kom rov ua tau qhov tseeb rau txhua qhov luam tawm. Yog hais tias lub rooj tsavxwm nkag mus rau hauv cov ntsia hlau yog thaiv los yog cov pins txhawb nqa nyob rau hauv txoj kev uas ua rau muaj kev cuam tshuam, qhov no tuaj yeem ua rau PCB lossis stencil puas.

Rail Width Verification:Muab ib lub PCB tso rau hauv cov ntsia hlau thiab xyuas cov zawv zawg clearance. Yog tias xoob dhau lawm, kev sib dhos yuav ua tsis tiav, yog tias nruj heev, lub rooj tsavxwm tuaj yeem deform.
Sensor Sensitivity:Xyuas seb lub rooj nkag nkag thiab tawm ntawm lub rooj tsavxwm puas muaj plua plav.
Txhawb Pin Kev Tshawb Fawb:Xyuas kom cov pins txhawb nqa tau ruaj ntseg thiab muab tso rau deb ntawm cov khoom ntawm PCB sab hauv qab kom tiv thaiv "flexing" los ntawm kev cuam tshuam rau luam ntawv flatness.

Phau Ntawv Qhia Txog Kev Ua Haujlwm: Xa mus rau ntu "Kev daws teeb meem" ntawm phau ntawv. Yog hais tias "board nkag tsis ua hauj lwm" tshwm sim, thawj zaug xyuas cov khiav tsav siv rau cov khoom txawv teb chaws.

CovNeoDen ND450ua pov thawj tias kev tsim qauv compact thiab kev tshaj lij tuaj yeem ua ke. Txawm li cas los xij, tus nqi siab -kev ua tau zoo tsis tau txhais hais tias cov qauv kev saib xyuas tuaj yeem cuam tshuam.

Los ntawm kev ua cov haujlwm saum toj no 5 kev tshuaj xyuas txhua hnub, koj tuaj yeem:

Ua kom ntau lawm uptime los ntawm 15-20%.
Txo qhov tsis xws luag los ntawm kev luam ntawv ntau dua 80%.
Tiv thaiv cov khoom tseem ceeb kim xws li cov nplais sib nqus thiab lub koob yees duab.

Rau txhua tus kws tshaj lij SMT siv zog ua haujlwm zoo, ND450 yog tus khub txhim khu kev qha. Muab nws 10 feeb ntawm kev saib xyuas txhua hnub, thiab nws yuav muab nqi zog rau koj nrog 24 teev ntawm cov zis ruaj khov.

Q1: Vim li cas ND450 tsis lees paub cov ntsiab lus?

A: Qhov no feem ntau yog tshwm sim los ntawm lub lens qias neeg, tsis txaus lub teeb siv, lossis oxidation ntawm cov ntsiab lus ntawm PCB nto.

Peb pom zoo ua ntej ntxuav lub lens thiab siv "Relock" muaj nuj nqi hauv software.

Q2: Dab tsi yog qhov zoo tshaj plaws squeegee siab teeb rau ND450?

A: Qhov no yuav tsum zoo -tuned raws li viscosity ntawm solder paste thiab thickness ntawm stencil.

Lub hauv paus ntsiab lus dav dav yog siv qhov tsawg kawg nkaus uas tsim nyog los xyuas kom meej tias cov tshuaj txhuam hniav yog "squeaked huv," yog li txuas ntxiv lub neej ntawm stencil.

Q3: Vim li cas ho tsis yog lub tshuab ntxhua khaub ncaws dispensing cawv?

A: Thov xyuas seb lub twj tso kua dej cawv puas tau kos hauv huab cua, lossis seb lub raj dej cawv puas tau qhuav tawm thiab ua rau txhaws vim yog siv sijhawm ntev.
