Kune PCB vagadziri veHDI mabhodhi, laser drill ndiyo yakanyanya kunaka sarudzo yekuchera chaiyo microvias.Aya ma microvias madiki muhukuru uye anoda kudhirowa kwakadzika kwakadzora.Kunyatsoita uku kunogona kuwanikwa kuburikidza ne lasers drills.Laser drilling ndiyo maitiro anoshandisa yakanyanya concentrated laser simba pakuchera (vaporizing) gomba.Laser drilling inogadzira maburi chaiwo paPCB board kuti ive nechokwadi chechokwadi kunyangwe uchibata nehudiki hwehukuru.Laser anogona kudhiraivha 2.5 kusvika 3-mil vias pane yakaonda furati girazi reinforcement.Kana iri dielectric isina kusimbiswa (isina girazi), zvinokwanisika kudhiza 1-mil vias uchishandisa lasers.Saka, laser drilling inokurudzirwa kuchera microvias.

Kunyangwe tichigona kudhiraivha tichishandisa maburi echidhayamita 6 mil (0.15 mm) nezvibooreso zvemuchina, mutengo wekushandisa unowedzera zvakanyanya sezvo zviboorero zvitete zvinoputika zviri nyore, uye zvinoda kugadzikiswa.Tichienzanisa nekuchera kwemuchina, zvakanakira kuchera lasers zvakanyorwa pazasi:

• Zvisiri-contact process:Laser drilling inzira isingabatanidzi zvachose uye nekudaro kukuvadzwa kunokonzerwa nedhill bhiti uye zvinhu nekuchera vibration kunobviswa.
• Kudzora chaiko:Iko kusimba kwedanda, kupisa kwekubuda, uye nguva yelaser beam iri pasi pesimba rekuchera laser tekinoroji, nekudaro izvo zvinobatsira kumisikidza akasiyana maumbirwo egomba nekunyatso.Kushivirira uku ± 3 mil sehuwandu hwakaderera pane kuchera kwemuchina nePTH kushivirira ± 3 mil uye NPTH kushivirira kwe ± 4 mil.Izvi zvinobvumira kuumbwa kwemapofu, kuvigwa, uye akaturikidzana vias pakugadzira HDI mabhodhi.

• High aspect ratio:Imwe yeanonyanya kukosha maparameter egomba rakaboorwa pane rakadhindwa redunhu bhodhi ndeye aspect ratio.Inomiririra kudzika kwegomba kusvika kugomba dhayamita ye via.Sezvo ma lasers achigona kugadzira maburi ane madhayamita madiki kwazvo anowanzo kubva pa3-6 mil (0.075mm-0.15mm), anopa chiyero chepamusoro.Microvia ine chimiro chakasiyana kana ichienzaniswa neyenguva dzose kuburikidza, zvichikonzera chiyero chakasiyana.Iyo yakajairika microvia ine chiyero che 0.75: 1.

• Zvinodhura:Laser drilling inokurumidza zvakanyanya kupfuura kuchera kwemuchina, kunyangwe yekuchera yakasvibirira yakaiswa vias pane multilayer board.Uyezve, nekufamba kwenguva, mari yekuwedzera kubva pakugara ichitsiva yakatyoka mabhiti echibhorani inowedzera uye kuchera kwemuchina kunogona kudhura zvakanyanya kana zvichienzaniswa nekuchera laser.

• Multi-tasking:Laser michina inoshandiswa kuchera inogona zvakare kushandiswa kune mamwe maitiro ekugadzira senge welding, kucheka, nezvimwe.

PCB vagadzirivane zvakasiyana-siyana zvingasarudzwa zve lasers.PCB ShinTech inoshandisa infrared uye ultraviolet wavelength lasers yekuchera uchigadzira HDI PCB.Yakasiyana laser musanganiswa inodiwa sezvo PCB vagadziri vanoshandisa akati wandei dielectric zvinhu seresin, yakasimbiswa prepreg, uye RCC.

Kusimba kwedanda, kupisa kwekubuda, uye nguva yelaser beam inogona kurongwa pasi pemamiriro akasiyana.Masimbi akadzikama anogona kuboorera nepakati pezvinhu zvakasiiwa asi achisiya simbi isina kukuvara.Kuti ticheke nesimbi negirazi, tinoshandisa matanda epamusoro-soro.Nepo matanda akadzika-fluence achida matanda e4-14 mil (0.1-0.35 mm) dhayamita, matanda epamusoro-soro anoda matanda anosvika 1 mil (0.02 mm) dhayamita.

Chikwata chekugadzira chePCB ShinTech chakaunganidza pamusoro pemakore gumi neshanu hunyanzvi mukugadzirisa laser uye yakaratidza rekodhi rekodhi yekubudirira muHDI PCB kupa, kunyanya mukugadzirwa kwePCB inoshanduka.Mhinduro dzedu dzakagadzirwa kuti dzipe mabhodhi edunhu akavimbika uye sevhisi yehunyanzvi ine mutengo wemakwikwi kutsigira bhizinesi rako mazano mumusika zvinobudirira.
