HDI Circuit Board HDI duab

1. While achieving low defect rate and high output, it can achieve stable production of HDI's conventional high-precision operation. E.g:

Advanced mobile phone board, CSP pitch tsawg dua 0.5mm (kev sib txuas nrog lossis tsis muaj xov hlau ntawm cov laug cam

board qauv yog 3 plus n ntxiv 3, nrog peb stacked vias ntawm txhua sab, 6 mus rau 8-txheej hlau tsis luam ntawv boards nrog stacked vias

In terms of imaging, such designs require ring widths less than 75micro;m, and in some cases even less than 50micro;m. These inevitably lead to low yields due to alignment issues. Additionally, driven by miniaturization, lines and pitches are getting finer—meeting this challenge requires a change in traditional imaging methods. This can be done by reducing the panel size, or by imaging the panel in several steps (four or six) using a shutter exposure machine. Both methods achieve better alignment by reducing the effects of material deformation. Changing the panel size resulted in a high cost of materials, and the use of a shutter exposure machine resulted in low throughput per day. Neither method can fully address material deformation and reduce plate-related defects, including the actual deformation of the plate as the batch/lot is printed.

2. Ua tiav cov khoom tsim nyog los ntawm kev luam tawm cov khoom xav tau ntawm cov vaj huam sib luag ib hnub. Raws li tau hais dhau los, qhov txheeb ze ntawm cov txiaj ntsig xav tau yuav tsum tau muab xam rau hauv cov kev cai raug. Txhawm rau kom ua tiav cov khoom tsim nyog, nws yog ib qho tsim nyog yuav tsum tau txais cov zis siab siab nrog kev pab los ntawm kev tswj tsis siv neeg.

3. Tsawg nqi ua haujlwm. Qhov no yog qhov yuav tsum tau loj rau txhua tus neeg tsim khoom ntim. Hauv hom LDI thaum ntxov, nws yuav tsum tau hloov cov yeeb yaj kiab qhuav ib txwm muaj nrog cov yeeb yaj kiab qhuav ntau dua, thiaj li ua tiav cov duab nrawm dua; los yog raws li lub teeb ci siv nyob rau hauv LDI hom, cov zaj duab xis qhuav tau hloov nrog ib qho sib txawv wavelength band. Hauv txhua qhov xwm txheej no, cov yeeb yaj kiab qhuav tshiab feem ntau yuav kim dua li cov yeeb yaj kiab qhuav siv los ntawm cov chaw tsim khoom.

4. Tau tshaj cov txheej txheem thiab cov txheej txheem ntau lawm. Cov txheej txheem thiab cov txheej txheem ntawm cov khoom loj feem ntau yog ua tib zoo teev kom ua tau raws li qhov yuav tsum tau ua ntawm cov khoom loj. Kev taw qhia txog ib qho kev ntsuas tshiab yuav tsum muaj kev hloov pauv me me rau txoj kev uas twb muaj lawm. Qhov no suav nrog kev hloov pauv tsawg kawg hauv cov yeeb yaj kiab qhuav siv, muaj peev xwm nthuav tawm cov txheej txheem ntawm cov npog ntsej muag, kev muaj peev xwm taug qab yuav tsum tau siv rau ntau lawm, thiab ntau dua.
