Kwa opanga ma PCB a HDI board, kubowola kwa laser ndiye njira yabwino kwambiri yoboolera ma microvias enieni.Tizilombo tating'onoting'ono tating'onoting'ono ndipo timafunika kubowola mozama molunjika.Kulondola uku kumatha kukwaniritsidwa ndi kubowola kwa laser.Kubowola kwa laser ndi njira yomwe imagwiritsa ntchito mphamvu zambiri za laser pobowola (vaporizing) dzenje.Kubowola kwa laser kumapanga mabowo enieni pa bolodi la PCB kuti zitsimikizire zolondola ngakhale mukuchita ndi zazing'ono kwambiri.Ma laser amatha kubowola ma vias 2.5 mpaka 3-mil pagalasi lolimba lolimba.Pankhani ya dielectric yopanda mphamvu (yopanda galasi), ndizotheka kubowola ma 1-mil vias pogwiritsa ntchito ma laser.Chifukwa chake, kubowola kwa laser kumalimbikitsidwa pobowola ma microvias.

Ngakhale titha kubowola kudzera m'mabowo a mainchesi 6 mamilimita (0.15 mm) pogwiritsa ntchito makina obowola, mtengo wopangira zida umakwera kwambiri popeza zobowola zopyapyala zimaduka mosavuta, ndipo zimafunika kusinthidwa pafupipafupi.Poyerekeza ndi kubowola makina, ubwino wa kubowola lasers zalembedwa pansipa:

• Njira yosalumikizana:Kubowola kwa laser ndi njira yosalumikizana konse ndipo chifukwa chake kuwonongeka komwe kumachitika pabowolo ndi zinthu pobowola kugwedezeka kumathetsedwa.
• Kuwongolera molondola:Kuchuluka kwa mtengo, kutulutsa kutentha, komanso kutalika kwa mtengo wa laser zimayendetsedwa ndi njira zobowola laser, zomwe zimathandiza kukhazikitsa mawonekedwe osiyanasiyana a dzenje molondola kwambiri.Kulekerera uku kwa ± 3 mil monga kuchuluka kwake kumakhala kotsika kuposa kubowola makina ndi PTH kulolerana ± 3 mil ndi NPTH kulolerana kwa ± 4 mil.Izi zimathandiza mapangidwe akhungu, kukwiriridwa, ndi zakhala zikuzunza m'miyoyo vias pamene kupanga HDI matabwa.

• Chigawo chapamwamba:Chimodzi mwazinthu zofunika kwambiri pabowo lobowoleredwa pa bolodi losindikizidwa ndi gawo la gawo.Zimayimira kuya kwa dzenje mpaka dzenje m'mimba mwake mwa via.Popeza ma lasers amatha kupanga mabowo okhala ndi ma diameter ang'onoang'ono kwambiri kuyambira 3-6 mil (0.075mm-0.15mm), amapereka chiŵerengero chapamwamba.Microvia ili ndi mbiri yosiyana poyerekeza ndi yanthawi zonse, zomwe zimapangitsa kuti pakhale gawo losiyana.Microvia wamba ali ndi gawo la 0.75: 1.

• Zotsika mtengo:kubowola kwa laser ndikothamanga kwambiri kuposa kubowola kwamakina, ngakhale pobowola modzaza ma vias pa bolodi lamitundu yambiri.Komanso, m'kupita kwa nthawi, ndalama zowonjezera zomwe zimabwerezedwa nthawi zambiri m'malo obowola osweka zimawonjezeka ndipo kubowola ndi makina kumatha kukhala kokwera mtengo kwambiri poyerekeza ndi kubowola kwa laser.

• Ntchito zambiri:Makina a laser omwe amagwiritsidwa ntchito pobowola amathanso kugwiritsidwa ntchito pazinthu zina zopangira monga kuwotcherera, kudula, ndi zina.

Opanga PCBndi mitundu yosiyanasiyana ya lasers.PCB ShinTech imagwiritsa ntchito ma laser a infrared ndi ultraviolet wavelength pobowola ndikupanga ma HDI PCB.Mitundu yosiyanasiyana ya laser ndiyofunikira popeza opanga PCB amagwiritsa ntchito zida zingapo za dielectric monga resin, reinforced prepreg, ndi RCC.

Kuchuluka kwa mtengo, kutulutsa kutentha, ndi kutalika kwa mtengo wa laser zitha kukonzedwa mosiyanasiyana.Mitengo yotsika kwambiri imatha kubowola muzinthu zakuthupi koma imasiya zitsulo zosawonongeka.Kudula zitsulo ndi galasi, timagwiritsa ntchito matabwa apamwamba kwambiri.Ngakhale matabwa otsika amafunikira matabwa a 4-14 mil (0.1-0.35 mm) m'mimba mwake, matabwa okwera kwambiri amafunikira midayo ya 1 mil (0.02 mm).

Gulu la opanga la PCB ShinTech lapeza ukadaulo wazaka 15 pakukonza laser ndipo latsimikizira mbiri yachipambano pakuperekedwa kwa HDI PCB, makamaka pakupanga kosinthika kwa PCB.Mayankho athu amapangidwa kuti apereke ma board odalirika ozungulira ndi ntchito zamaluso ndi mtengo wampikisano kuti athandizire malingaliro anu abizinesi pamsika bwino.

Chonde tumizani kufunsa kwanu kapena pempho la mtengo wamtengo wapatali kwa ifesales@pcbshintech.comkuti mulumikizane ndi m'modzi wa oyimira athu ogulitsa omwe ali ndi chidziwitso chamakampani kuti akuthandizeni kupeza malingaliro anu kuti mugulitse.
