Laser npav tshuab yog laum vim qhov nqaj me me loj thiab tsis tshua muaj kev ntxhov siab ntawm UV lasers, suav nrog dhau ntawm-qhov, micro-qhov thiab qhov muag tsis pom qhov. Lub UV laser system kawm tawm los ntawm cov txheejtxheem los ntawm kev tsom mus rau kab ntsug ntsug ncaj ntawm lub substrate. Nyob ntawm cov khoom siv uas siv, cov qhov me me li 10 μm tuaj yeem ua kom tau. UV lasers yog qhov tshwj xeeb tshaj yog thaum nqus ntau txheej. Ntau txheej PCBs laminated ua ke siv kub tuag-casting. Cov kev sib cais "semi-kho" sib cais tshwm sim, tshwj xeeb tshaj yog tom qab ua tiav ntawm cov cua sov siab dua. Txawm li cas los xij, qhov tsis tshua muaj kev ntxhov siab los ntawm UV lasers daws cov teeb meem no. Lub 14 mil multilayer board yog drilled nrog 4 mil txoj kab uas hla. Daim ntawv thov no rau kev hloov pauv polyimide tooj liab-plated substrate pom tsis muaj kev sib cais ntawm cov khaubncaws sab nraud povtseg. Hais txog qhov tsis tshua muaj kev ntxhov siab ntawm UV lasers, muaj lwm lub ntsiab lus tseem ceeb: txhim kho cov ntaub ntawv tawm. Yield yog qhov feem pua ntawm cov laug cam uas muab tshem tawm los ntawm ib lub rooj.
Thaum lub sij hawm tsim tawm, ntau yam mob yuav ua rau kev puas tsuaj ntawm lub rooj tsav xwm hauv Circuit Court, suav nrog cov pob qij txha pob txha, cov khoom tawg, lossis cov khoom xaib. Txawm qhov twg yuav tuaj yeem ua rau cov laug cam Circuit Court muab pov rau hauv lub khib nyiab ntau dua rau hauv lub thawv xa khoom ntawm cov kab ntau lawm. Daim ntawv thov ntawm UV laser khoom daws cov teeb meem no rau ntau! Qhov no yog qhov laj thawj tseem ceeb rau nws xaiv.
