Daim ntawv thov ntawm UV Laser Processing hauv PCB Manufacturing & Substrate Materials

Ultraviolet (UV) laser thev naus laus zis tau dhau los ua cov cuab yeej tseem ceeb hauv kev ua haujlwm siab -Printed Circuit Board (PCB) kev tsim khoom. Kev khiav hauj lwm feem ntau ntawm 355 nm wavelength, UV lasers siv lub "txias ua" tshuab (photolytic ablation) uas ua txhaum cov tshuaj tiv thaiv ncaj qha es tsis txhob cia siab rau thermal melting. Qhov no txo ​​cov cua sov-Teb chaws cuam tshuam (HAZ), tshem tawm thermal degradation thiab mechanical stress on ilv substrates.

Hauv qab no yog plaub daim ntawv thov kev lag luam uas UV lasers outperform ib txwm siv tshuab thiab thermal txoj kev. Txhawm rau nkag siab tias PCB substrates sib txawv li cas rau laser wavelengths, tshawb xyuas peb cov lus qhia ntxaws ntxaws ntawmkev sib raug zoo ntawm ntau hom PCB thiab laser ua.

UV lasers muab siab -ceev, siab- daws teeb meem nto etching, ua rau lawv zoo tagnrho rau kev ceev Circuit Court qauv-tshwj xeeb tshaj yog thaum lub sij hawm R&D thiab prototyping theem.

Ultra-Cov kab mob zoo:Nrog rau lub teeb tsom teeb pom kev tsuas yog 10-20 μm, UV lasers tuaj yeem ua rau micro- teev cov kab hluav taws xob ntawm cov kab hluav taws xob hloov tau yooj yim (FPC) thiab cov khoom siv tshwj xeeb ceramic substrates uas cov cuab yeej siv tshuab tsis tuaj yeem ua tiav.

Proven Precision:Piv txwv li, ntawm 0.75 "× 0.5" sintered ceramic substrate nrog tungsten / npib tsib xee / tooj liab txheej txheej, UV lasers tuaj yeem txhim kho 2-mil kab dav dav nrog 1-mil qhov sib nrug (tag nrho cov suab ntawm tsuas yog 3 mils).

Prototyping Efficiency:R&D labs tuaj yeem rov ua dua thiab tsim cov qauv ntsuas hluav taws xob tiav hauv feeb yam tsis tau tos cov duab kim - npog ntsej muag.

Rau qhov kev xav dav dav ntawm kev tsim hluav taws xob niaj hnub no, saib peb lub ntsiab lus ntawmDaim ntawv thov laser hauv PCB & FPC manufacturing.

PCB depanelization- tshem tawm ib lub rooj tsav xwm los ntawm lub vaj huam sib luag tus tswv- nthuav tawm cov teeb meem tseem ceeb vim tias cov substrates ua nyias thiab hloov tau yooj yim dua.

• Zero Mechanical Stress:Ib txwm siv tshuab depanelization txoj kev (xws li V- txiav cov qhab nia lossis kev siv tshuab ua haujlwm) ua rau lub cev muaj kev ntxhov siab uas tuaj yeem tawg tsis yooj yim substrates, burr npoo, lossis detach nto -mount cov khoom (SMDs). UV laser singulation tshem tawm txhua yam quab yuam nkaus.
• Superior Thermal Control vs CO₂ Lasers:Tsis zoo li ib txwmRF CO2 laser txoj kev tshuabuas txiav los ntawm thermal melting thiab tawm qhov pom ntawm ntug charring, UV laser "txias ua" zoo tshem tawm thermal stress thiab thermal distortion.
• Maximized Board vaj tse:Vim hais tias kev txiav laser yuav tsum tau "txiav margins" tsawg heev (kom- tawm tsam), cov khoom siv hluav taws xob tuaj yeem muab tso rau ze rau ntawm lub rooj tsavxwm. Qhov no tso cai rau cov tuam txhab ntim ntau lub voj voog rau ib lub vaj huam sib luag, txo cov khoom pov tseg thiab ua kom muaj txiaj ntsig zoo.

Rau qhov tshwj xeeb saj zawg zog circuitry, siv lub siabFPC laser txiav tshuabkom siab precision yam tsis muaj ntug distortion. Koj tuaj yeem tshawb xyuas lub ntsiabQhov zoo ntawm PCB laser txiav tshuab, tshuaj xyuas laser engraving & txiav tshuab rau PCB, thiab kawm txog tag nrhodaim ntawv thov thiab kev loj hlob ntawm PCB laser txiav.

As electronic designs miniaturize, the demand for high-density interconnect (HDI) PCBs requires smaller via diameters and tighter tolerances. UV lasers ua tau zoo ntawm drilling microvias, dig muag vias, faus vias, thiab dhau ntawm - qhov.

• Micro-Size Features:Los ntawm kev tsom mus rau txoj kab ntsug nruj los ntawm lub substrate, UV lasers tuaj yeem txhim kho kev xyaum hla mus txog 10 μm hauv txoj kab uas hla, nyob ntawm cov khoom siv.
• Tiv thaiv Multilayer Delamination:Multilayer PCBs muaj xws li laminated khaubncaws sab nraud povtseg nyob rau hauv tshav kub thiab siab. Siab - cov khoom siv ua cua sov feem ntau ua rau delamination ntawm semi- kho prepreg interfaces. UV lasers 'tsis yog-thermal ablation tiv thaiv txheej txheej sib cais, solder sib koom ua ke, thiab substrate burning.

Thaum sub-micron tolerances thiab ultrashort mem tes ntev yuav tsum tau, manufacturers feem ntau soj ntsuam ultrafast optics. Nyeem peb qhov kev sib piv ntawmfemtosecond vs nanosecond laser micro-drillingthiab nrhiav tau li casfemtosecond laser micro-drilling ua haujlwm ntawm molybdenumxaiv txoj cai pulse configuration rau koj ntawm daim ntawv thov.

Micro & Nano Precision Laser Ua Khoom

UV laser tshuab muab tshwj xeeb z-axis qhov tob tswj ntawm software- coj lub zog pulse thiab scan rov ua dua, tso cai qhov tob tob- tswj cov khoom ablation.

• Lub hom phiaj tshem tawm cov khoom:Lub laser tuaj yeem xaiv cov khaubncaws sab nraud povtseg los ntawm cov ntaub qhwv hlau (nto tu) lossis cov hnab ntim cov qhov tob uas tsis muaj kev puas tsuaj rau cov txheej txheem txheej txheem.
• Component Embedding:Qhov zoo tshaj plaws rau kev tsim micro- kab noj hniav uas yuav tsum tau siv rau embedding IC chips ncaj qha rau hauv substrate boards.
• Multi-Qhia qhov tob tob:Piv txwv li, ntawm polyethylene lossis polymer substrates, UV laser tuaj yeem ua tiav cov kauj ruam ablation dhau-xws li carving 2-mil trench, nqis mus rau 8 mils, thiab ua tiav ntawm 10 mils nrog sub-micron qhov tob repeatability.

Qhov tob zoo sib xws-cov txheej txheem tswj tau nquag siv rau cov ntaub ntawv tawv, nkig; kawm ntxiv txoglaser scribing khoom thiab nws cov ntawv thov kev lag luam.

Qhov txiaj ntsig tseem ceeb ntawm UV laser tshuab yog nws ntau yam. Ib qho chaw UV laser ib leeg tuaj yeem ua qhov drilling, depanelizing, circuit etching, thiab kab noj hniav engraving hauv ib qho kev sib koom ua ke.

• Eliminates Process Bottlenecks:Consolidating ntau yam machining cov kauj ruam mus rau ib lub tshuab yuav txo tau ib feem - tuav kev puas tsuaj thiab alignment yuam kev tshwm sim los ntawm kev hloov ntawm chaw ua hauj lwm.
• Ntxuav, khib nyiab- Pub dawb tawm los:Photolytic ablation yields du npoo nrog xoom khib nyiab buildup, tshem tawm qhov xav tau rau kev txhoj puab heev tom qab - txheej txheem tshuaj ntxuav los yog tshuab deburring.

Txhawm rau kom nkag siab tob rau hauv kev ua cov txheej txheem, tshuaj xyuasqhov tseem ceeb thiab txoj hauv kev ua haujlwm ntawm PCB laser ua.
