Taw qhia
NtauNeoDen YY1cov neeg siv feem ntau ntsib kev tsis sib haum xeeb thaum lub sijhawm ua haujlwm: txawm hais tias calibrated qhov chaw taub hau, zoo sib xws nozzles, thiab yuam kev - pub dawb pub, vim li cas cov teeb meem zoo li tag nrho misalignment, skewed zoo - suab IC qhov chaw, thiab BGA misalignment tseem muaj nyob rau thaumme -batch ntau lawm?
Cov lus teb feem ntau yog nyob rau hauv PCB loading method, precision ntawm panelization txhais, thiab seb Fiducial puas siv tau zoo.
Kab lus no piav qhia txog yuav ua li cas txhawm rau txhim kho NeoDen YY1 qhov raug tso kawm los ntawm "usable" mus rau "kev lag luam- qib kev ntseeg tau" los ntawm kev tshawb fawb PCB panelization nqis thiab optimized Fiducial configurations.
I. Yam yuavtsum tau kawm uantej: PCB Mounting & Origin Definition
1. Kev ruaj ntseg kho kom tshem tawm Micro-Kev tshem tawm
Raws li Tshooj 4 ntawm lub"NeoDenYY1 manual", PCBs yuav tsum tau kho rau lub workbench siv qhov chaw strips lossis pins. Ib qho me ntsis warping, looseness, los yog thermal expansion/contraction yuav raug nthuav dav thaum muab tso rau.
Cov lus pom zoo ua haujlwm:
- Siv cov pins txhawb nqa nrog lub hauv paus sib nqus kom paub tseeb tias tag nrho plaub lub PCB cov ces kaum pw tiaj tus thiab yaug.
- Nyob rau hauv qhov chaw siab - qhov kub thiab txias, tso cai rau PCBs so rau 10 feeb ua ntej qhov chaw tso tawm kev ntxhov siab.
2. Lub hauv paus chiv keeb yuav tsum tau txhais thiab rov tsim dua
NeoDen YY1 txoj cai hais tias PCB kev tswj hwm qhov system pib los ntawm hauv qab - sab laug ces kaum (hauv qab txheej yog los ntawm hauv qab - sab xis). Cov ntsiab lus no yog siv rau txhua qhov kev sib koom ua ke.
Kev teeb tsa:
Hauv [System Settings] → [PCB Keeb Kwm], manually txav lub koob yees duab tso rau hauv PCB hauv qab -sab laug ces kaum, sau cov kev tswj xyuas, thiab txuag.
II.Panelization Efficiency Settings: Qhov tseem ceeb rau Batch Efficiency
Panelization yog tus qauv coj los txhawb kev ua haujlwm hauvme -rau- nruab nrab batch ntau lawm. Txawm li cas los xij, kev teeb tsa vaj huam sib luag tsis raug tuaj yeem ua rau tag nrho misalignment ntawm sub-boards.
1. NeoDen YY1 Panelization Txheej Txheej Txheem
Ntawm nplooj ntawv [File Editing] → [Panelization], yooj yim cov tswv yim:
- X / Y qhov ntev ntawm ib lub rooj me me (unit: mm).
- Tus naj npawb ntawm cov laug cam me nyob rau hauv kab rov tav / ntsug ntawm lub rooj tsavxwm loj.
- Lub kaw lus yuav cia li tsim cov panelization matrix.
Kev ceeb toom tseem ceeb:
Input qhov ntev yuav tsum yog qhov ntsuas qhov tseeb, tsis yog qhov tseem ceeb ntawm cov ntaub ntawv Gerber! Peb pom zoo kom siv YY1 tus xaiv-thiab- tso lub koob yees duab los ntsuas qhov sib nrug:
- Muab lub koob yees duab tso rau hauv qab -sab laug ces kaum ntawm thawj lub rooj tsavxwm.
- Txav mus rau hauv qab -sab laug ces kaum ntawm lub rooj tsavxwm thib ob.
- Sau qhov sib txawv XY raws li lub vaj huam sib luag sib nrug.
2. Vaj Huam Sib Luag Keeb Kwm Txoj Cai
- Lub hauv paus chiv keeb ntawm thawj sub- pawg thawj coj saib yuav tsum ua tib zoo sib xws nrog lub ntsiab PCB.
- Yog hais tias lub vaj huam sib luag muaj V- txiav los yog microvias, tso cai rau 0.2–0.3mm kev nyab xeeb npoo tiv thaiv lub koob yees duab los ntawm misidentifying npoo raws li Fiducial.
III. Fiducial
Fiducial yog qhov tseem ceeb rau kev them nyiaj PCB stretching, shrinking, los yog kev sib hloov thaum lub sij hawm cov txheej txheem xws lisolder paste luam ntawvthiabreflow soldering.
1. Ob hom Fiducial thiab teeb tsa lub tswv yim
| Hom | Muaj nuj nqi | Teeb pom kev zoo |
| Ntiaj teb no Fiducial | Kho tag nrho vaj huam sib luag txoj hauj lwm thiab kev taw qhia | Muab 2+ rau ntawm cov ces kaum vaj huam sib luag los yog kab pheeb ces kaum, lub voj voos zoo tshaj plaws |
| Local Fiducial | Kho siab -cov khoom muaj tseeb (piv txwv li, 0.5mm QFP, BGA) | Muab 1 rau ntawm txhua sab ntawm qhov ntom ntom - ntim ICs, Tsawg dua lossis sib npaug li 5 hli los ntawm cov khoom siv |
Nco tseg:
- Fiducial yuav tsum yog ncig nrog qhov sib txawv ntawm qhov chaw ib puag ncig (piv txwv li, liab qab tooj liab pads).
- Cov cheeb tsam ib puag ncig yuav tsum tsis muaj cov qauv zoo sib xws (piv txwv li, cov ntsiab lus ntsuas, txhob lo lo ntxhuav-screen dots) txhawm rau tiv thaiv qhov tsis raug.
- Yog tias kev lees paub ua tsis tiav, lub tshuab tso tawm "beep-beep-beep" ceeb toom- hloov lossis kho tam sim.
2. Fiducial Recognition Optimization Tips
- Tsis txhob cuam tshuam lub teeb muaj zog: Phau ntawv qhia meej meej hais tias "Tshwj xeeb hnub ci txwv tsis pub"- txwv tsis pub lub koob yees duab lees paub ua tsis tiav.
- Kho lub koob yees duab pib: Hauv [System Settings] → [Camera Threshold], txo tus nqi txhim kho kev paub txog kev tsaus ntuj.
- Siv "Ib kauj ruam ib kauj ruam" rau kev txheeb xyuas: Ua ntej tso, nyem "Ib kauj ruam ib zaug." Lub kaw lus yuav xub paub txog qhov nyiaj tau los thiab tso saib cov nqi them nyiaj. Txheeb xyuas qhov tseeb ua ntej khiav tag nrho lub rooj tsavxwm.
IV. Precision Verification thiab kev daws teeb meem ua ntej tso
1. Cov kauj ruam yuav tsum tau ua
- Siv pob tshab ob npaug -ib daim kab xev rau PCB (tsis txhob fiducial).
- Qhib hom "Ib Kauj Ruam Ib Leeg" txhawm rau saib seb lub taub hau qhov chaw tso cai puas haum rau txhua qhov sub- lub hauv paus chiv keeb.
- Tom qab kev lees paub tseeb, txheeb xyuas yog tias lub kaw lus tau kho X / Y / lub kaum ntse ntse.
2. Cov teeb meem thiab kev daws teeb meem
| Qhov teeb meem | Ua Tau | Kev daws |
| Tag nrho board offset | PCB keeb kwm yuam kev / Tsis muaj teeb meem | Redefine keeb kwm, yuam kev teeb tsa |
| Misalignment hauv vaj huam sib luag | Qhov sib txawv ntawm vaj huam sib luag input tsis raug | Ntsuas cov sub-board nrug nrog lub koob yees duab, rov- tawm tswv yim |
| Kev lees paub tsis raug | Lub teeb cuam tshuam / Tsis txaus qhov sib txawv | Thaiv lub teeb, txo lub koob yees duab pib, hloov chaw fiducial |
| Misaligned zoo - suab IC | Nthuav lub zos Fiducial | Ntxiv Fiducial hauv zos ntawm ob sab ntawm IC |
| Zuag qhia tag nrho angular rotation | Tsuas yog 1 Fiducial set | Yuav tsum teeb 2+ Fiducial los xam lub kaum sab xis |
V. Cov kev coj ua zoo tshaj plaws
Txhawm rau ua kom tiav NeoDen YY1 qhov tseeb, tswj PCB tsim, Gerber tso zis, thiab tshuab teeb tsa:
1 Tsim Phase
- Txuag yam tsawg kawg 2 tus qauv ncig fiducials (1.0–1.5mm txoj kab uas hla) rau sub-board.
- Kom meej meej cim qhov sib nrug ntawm vaj huam sib luag kom tsis txhob muaj qhov tsis sib haum xeeb.
2. Gerber Export Phase
- Teem EDA software keeb kwm rau hauv qab - sab laug ces kaum.
- Tshem tawm ntawm - qhov khoom ua ntej CSV export.
3. NeoDen YY1 Kev Ua Haujlwm
- Txheeb xyuas qhov ntev ntawm vaj huam sib luag los ntawm kev ntsuas lub cev, tsis yog qhov tseem ceeb theoretical.
- Validate Fiducial recognition stability tom qab txhua lub board hloov.
- Pab kom cov neeg siv khoom hauv zos rau siab - cov rooj tsav xwm muaj tseeb.
Xaus
NeoDen YY1 muaj lub peev xwm kho vajtse kom raug qhov chaw siab, tab sis kev paub txog qhov muaj peev xwm no nyob ntawm tus neeg teb xov tooj kev nkag siab thiab kev tswj hwm ntawm PCB kev sib koom tes.
Los ntawm kev tshawb fawb txog kev teeb tsa vaj huam sib luag, muab tswv yim tso Fiducial, thiab nruj me ntsis xyuas lub hauv paus chiv keeb, koj tuaj yeem tsis tsuas yog daws qhov kev tso kawm tsis raug tab sis kuj hloov YY1 mus rau qhov siab - tawm los, siab - ua haujlwm tau zoo, thiab txhim khu kev qha ntau lawm.
