Rau PCB cov tuam txhab ntawm HDI boards, laser laum yog qhov kev xaiv zoo tshaj plaws rau kev drilling precision microvias.Cov microvias no me me thiab xav tau kev tswj qhov tob tob.Qhov kev txiav txim siab no feem ntau tuaj yeem ua tiav los ntawm lasers xyaum.Laser drilling yog txheej txheem uas siv lub zog muaj zog laser ntau rau drilling (vaporizing) lub qhov.Laser drilling tsim cov qhov tseeb ntawm lub rooj tsavxwm PCB kom paub tseeb tias qhov tseeb txawm tias qhov tsawg tshaj plaws ntawm qhov ntau thiab tsawg.Lasers tuaj yeem laum 2.5 mus rau 3-mil vias ntawm lub iav tiaj tiaj tiaj.Nyob rau hauv cov ntaub ntawv ntawm ib tug unreinforced dielectric (tsis muaj iav), nws muaj peev xwm mus laum 1-mil vias siv lasers.Li no, laser drilling yog pom zoo rau drilling microvias.

Txawm hais tias peb tuaj yeem laum los ntawm qhov ntawm txoj kab uas hla 6 mil (0.15 mm) nrog cov khoom siv kho tshuab, cov cuab yeej siv tau nce ntau vim tias cov laum nyias nyias yooj yim heev, thiab xav tau kev hloov ntau zaus.Muab piv rau cov tshuab drilling, qhov zoo ntawm lasers drilling yog teev hauv qab no:

• Cov txheej txheem tsis sib cuag:Laser drilling yog tus txheej txheem tsis sib cuag thiab yog li ntawd qhov kev puas tsuaj tshwm sim ntawm lub laum me ntsis thiab cov khoom siv los ntawm kev co drilling yog tshem tawm.
• Precise tswj:Cov nqaj siv zog, cov khoom siv hluav taws xob, thiab lub sijhawm ntawm lub teeb laser yog nyob rau hauv kev tswj ntawm laser drilling cov tswv yim, yog li uas yuav pab tsim kom muaj qhov sib txawv ntawm cov duab nrog cov neeg siab.Qhov no kam rau ua ± 3 mil raws li qhov siab tshaj plaws yog qis dua txhua yam drilling nrog PTH kam rau ua ± 3 mil thiab NPTH kam rau ua ntawm ± 4 mil.Qhov no tso cai rau tsim qhov muag tsis pom, faus, thiab stacked vias thaum tsim HDI boards.

• High nam piv:Ib qho ntawm qhov tseem ceeb tshaj plaws ntawm qhov drilled qhov ntawm lub rooj tsav xwm luam tawm yog qhov piv txwv.Nws sawv cev rau lub qhov tob rau lub qhov taub ntawm ib lub via.Txij li cov lasers tuaj yeem tsim qhov nrog cov kab me me uas feem ntau yog li ntawm 3-6 mil (0.075mm-0.15mm), lawv muab qhov sib piv siab.Microvia muaj qhov sib txawv profile piv rau ib txwm dhau los, ua rau muaj qhov sib txawv ntawm qhov sib txawv.Ib qho microvia ib txwm muaj qhov sib piv ntawm 0.75: 1.

• Nqi-zoo:laser drilling yog nrawm dua li cov tshuab drilling, txawm tias qhov drilling ntom ntom tso rau ntawm lub rooj tsavxwm multilayer.Ntxiv mus, raws li lub sij hawm dhau mus, tus nqi ntxiv los ntawm kev hloov cov khoom siv tho qhov tawg ntxiv thiab cov tshuab drilling tuaj yeem ua tus nqi kim dua piv rau laser drilling.

• Multi-tasking:Laser tshuab siv rau drilling kuj tseem siv tau rau lwm cov txheej txheem tsim xws li vuam, txiav, thiab lwm yam.

PCB manufacturersmuaj ntau yam kev xaiv ntawm lasers.PCB ShinTech deploys infrared thiab ultraviolet wavelength lasers rau drilling thaum ua HDI PCBs.Kev sib txawv ntawm laser sib txuas yog tsim nyog raws li PCB cov tuam txhab siv ntau cov khoom siv hluav taws xob xws li cob, cov prepreg, thiab RCC.

Cov nqaj siv zog, cov zis tawm hluav taws xob, thiab lub sijhawm ntawm lub laser beam tuaj yeem ua haujlwm raws li qhov xwm txheej sib txawv.Low-fluence beams tuaj yeem xyaum los ntawm cov khoom siv organic tab sis tawm cov hlau tsis muaj kev puas tsuaj.Txhawm rau txiav cov hlau thiab iav, peb siv cov kab hluav taws xob siab.Thaum cov kab hluav taws xob tsawg yuav tsum tau kab teeb ntawm 4-14 mil (0.1-0.35 mm) inch, high-fluence beams xav tau kab teeb ntawm li 1 mil (0.02 mm) inch.

Pab pawg tsim khoom ntawm PCB ShinTech tau sau ntau tshaj 15 xyoo kev txawj ntse hauv kev ua laser thiab tau ua pov thawj cov ntaub ntawv ntawm kev ua tiav hauv HDI PCB muab, tshwj xeeb tshaj yog nyob rau hauv kev hloov pauv PCB.Peb cov kev daws teeb meem yog engineered los muab kev txhim khu kev qha Circuit Court boards thiab kev pab cuam nrog cov nqi sib tw los txhawb koj cov tswv yim kev lag luam rau hauv kev ua lag luam zoo.
