Product Detail

Nezve Iyo HDI PCB

Nekuda kwesimba rekuchera chishandiso, mutengo wekuchera kwechinyakare PCB wakakwira zvakanyanya kana dhayamita yekuchera yasvika 0.15mm, uye zvinonetsa kugadzirisa zvakare.Kudhirowa kweHDI PCB board hakuchatsamira pane zvechinyakare zvemuchina kuchera, asi kunoshandisa laser drilling tekinoroji.(saka dzimwe nguva inodaidzwa kuti laser plate.) Gomba rekuchera dhayamita reHDI PCB board rinowanzoita 3-5mil (0.076-0.127mm), uye upamhi hwemutsara hunowanzo 3-4mil (0.076-0.10mm).Ukuru hwepadhi hunogona kuderedzwa zvakanyanya, saka kugovera kwemutsara kwakawanda kunogona kuwanikwa munzvimbo yeyuniti, zvichikonzera kubatana kwepamusoro-density.

Kubuda kweHDI tekinoroji inochinjika uye inosimudzira kusimudzira kwePCB indasitiri.Saka kuti yakawedzera dense BGA uye QFP inogona kurongeka muHDI PCB board.Parizvino, tekinoroji yeHDI yakashandiswa zvakanyanya, iyo yekutanga-odha HDI yakashandiswa zvakanyanya mukugadzirwa kwe0.5 pitch BGA PCB.

Kuvandudzwa kweHDI tekinoroji kunokurudzira kuvandudzwa kwechip tekinoroji, iyo inosimudzira kuvandudzwa uye kufambira mberi kweHDI tekinoroji.

Parizvino, BGA chip ye0.5pitch yave kushandiswa zvakanyanya nevainjiniya vekugadzira, uye kona yekutengesa yeBGA yachinja zvishoma nezvishoma kubva pachimiro chepakati chekuchera kunze kana chepakati chekudzika kusvika pachimiro chepakati chiratidzo chekuisa uye kubuda kunoda waya.

Zvakanakira Mapofu Via Uye Kuvigwa Via PCB

Kushandiswa kwemapofu uye kuvigwa kuburikidza nePCB kunogona kuderedza zvakanyanya saizi uye mhando yePCB, kuderedza huwandu hwezvikamu, kugadzirisa kuenderana kwemagetsi, kuwedzera maficha ezvigadzirwa zvemagetsi, kuderedza mutengo, uye kuita kuti dhizaini ishande zviri nyore uye nekukurumidza.Muchinyakare PCB dhizaini uye machining, kuburikidza negomba kunounza matambudziko mazhinji.Chekutanga pane zvese, ivo vanotora yakawanda nzvimbo inoshanda.Chechipiri, huwandu hukuru hwemaburi munzvimbo imwechete zvakare hunokonzera chipingamupinyi chikuru kunzira yemukati yemukati yeakawanda-layer PCB.Aya nemaburi anotora nzvimbo inodiwa pakufamba.Uye kudhirowa kwemuchina kuchave kuri kuita basa rakapetwa makumi maviri senge isiri-perforating tekinoroji.
