Mazuvano, nekukasira kunatsurudzwa kwezvigadzirwa zvemagetsi, kudhindwa kwePCB kwawedzera kubva pamabhodhi e-single-layer board kusvika kune maviri-layer board uye ma-multi-layer board ane zvinodiwa zvakanyanya. Naizvozvo, pane zvakawanda uye zvakawanda zvinodiwa pakugadziriswa kwemakomba ebhodhi redunhu, senge: dhayamita yegomba iri kuita diki uye diki, uye chinhambwe pakati pegomba negomba chiri kuita diki uye diki. Zvinonzwisisika kuti fekitori yebhodhi parizvino inoshandisa yakawanda epoxy resin-based composite zvinhu. Tsanangudzo yehukuru hwegomba ndeyekuti dhayamita iri pasi pe 0.6 mm yemakomba madiki uye 0.3 mm ye micropores. Nhasi ini ndichasuma nzira yekugadzirisa ye microholes: mechanical drilling.
Kuti tive nechokwadi chepamusoro chekugadzirisa uye kunaka kwegomba, tinoderedza chikamu chezvigadzirwa zvisina kukwana. Mukuita kwekuchera kwemagetsi, zvinhu zviviri, axial simba uye torque yekucheka, zvinofanirwa kutariswa, izvo zvinogona kukanganisa zvakananga kana zvisina kunanga kunaka kwegomba. Iyo axial simba uye torque ichawedzera nekudya uye hupamhi hwekucheka kwekucheka, ipapo kukurumidza kwekucheka kuchawedzera, kuitira kuti nhamba yefibers yakachekwa pane imwe nguva yeyuniti iwedzere, uye chimbo chekupfeka chichawedzerawo nokukurumidza. Nokudaro, hupenyu hwechibhorani hwakasiyana nemakomba ehukuru hwakasiyana. Mushandi anofanirwa kujairana nekushanda kwemidziyo uye kutsiva chibooreso nenguva. Ichi ndicho chikonzero mutengo wekugadzirisa we microholes wakakwira.
Mune axial simba, iyo static chikamu FS inokanganisa kucheka kweGuangde, nepo iyo inoshanduka chikamu FD inonyanya kukanganisa kucheka kweiyo huru yekucheka. The dynamic component FD ine simba guru pakushata kwepamusoro pane static component FS. Kazhinji, kana aperture yegomba rakagadzirwa isati yasvika 0.4mm, iyo static chikamu FS inoderera zvakanyanya nekuwedzera kweaperture, nepo maitiro eiyo dynamic chikamu FD inoderera iri flat.
Kupfeka kwePCB drill kune hukama nekumhanya kwekucheka, chiyero chekudya, uye saizi yeslot. Huyero yeradius ye drill bit kusvika paupamhi hwegirazi fiber ine simba guru pahupenyu hwekushandisa. Iyo yakakura reshiyo, yakakura hupamhi hwefiber bundle yakachekwa nechishandiso, uye kuwedzera kwechishandiso kupfeka. Mukushanda kwekushandisa, hupenyu hwe 0.3mm drill hunogona kuboora 3000 maburi. Iyo yakakura chibooreso, maburi mashoma anoboorwa.
Kuti udzivise matambudziko akadai se delamination, kukuvara kwegomba madziro, mavara, uye maburrs pakuchera, tinogona kutanga taisa 2.5 mm ukobvu pedhi pasi pechifukidziro, toisa ndiro yemhangura yakavharwa padhi, tozoisa pepa realuminium pa bhodhi rakapfeka mhangura. Basa realuminium sheet ndeye 1. Kuchengetedza bhodhi repamusoro kubva kune zvinyorwa. 2. Kupisa kwakanaka kwekupisa, iyo drill bit ichaunza kupisa pakuchera. 3. Buffering effect / drilling effect kudzivirira kutsauka gomba. Iyo nzira yekudzikisa maburrs ndeye kushandiswa kweiyo vibration drilling tekinoroji, kushandisa carbide drills kudhiraivha, kuoma kwakanaka, uye saizi uye chimiro chechishandiso chinodawo kugadziriswa.
