Chii chinonzi HDI (High Density Interconnect) PCB board?

High density Interconnect (HDI) PCB, imhando yakadhindwa yedunhu bhodhi kugadzirwa (tekinoroji), kushandiswa kwegomba diki-mapofu, tekinoroji yakavigwa gomba, bhodhi redunhu rine huwandu hwakanyanya hwekugovera density. Nekuda kwekuenderera mberi kwekuvandudza tekinoroji yeakakwira-kumhanya chiratidzo chemagetsi zvinodiwa, bhodhi redunhu rinofanirwa kupa impedance control ine ac hunhu, yakakwira frequency kutapurirana kugona, kuderedza isina kufanira radiation (EMI) zvichingodaro. Uchishandisa Stripline, Microstrip chimiro, akawanda-layer dhizaini inova yakakosha. Kuti uderedze dambudziko remhando yekufambiswa kwechiratidzo, iyo insulation zvinhu ine yakaderera dielectric coefficient uye yakaderera attenuation rate inogamuchirwa. Kuti uenderane neiyo miniaturization uye akatevedzana emagetsi zvikamu, density yedare redunhu ichawedzerwa nguva nenguva kuti isangane nezvinodiwa.

HDI (high density interconnection) redunhu bhodhi rinowanzobatanidza laser bofu gomba uye mechanical bofu gomba;
Kazhinji kuburikidza negomba rakavigwa, gomba rebofu, gomba rinoputika, gomba rakadzika, gomba rakavigwa, kuburikidza negomba, gomba remapofu rinozadza electroplating, mutsara mutete diki gap, ndiro microhole uye mamwe maitiro ekuwana conduction pakati pemukati nekunze kwezvikamu, kazhinji mapofu. dhayamita yakavigwa haisi yakakura kudarika 6mil.

HDI redunhu bhodhi rakakamurwa kuita akati wandei uye chero layer yekubatanidza

Chekutanga-odha HDI chimiro: 1+N+1 (kudzvanya kaviri, laser kamwe)

Chechipiri-odha HDI chimiro: 2+N+2 (kudzvanya kwe3 nguva, laser kwe2 nguva)

Yechitatu kurongeka HDI chimiro: 3+N+3 (kudzvanya 4 nguva, laser 3 nguva)Kurongeka kwechina

HDI chimiro: 4+N+4 (kudzvanya kashanu, laser 5 nguva)

Uye chero HDI
