Ohun ti o jẹ HDI (High Density Interconnect) PCB Board?

Ga iwuwo Interconnect (HDI) PCB, ni a irú ti tejede Circuit ọkọ gbóògì (ọna ẹrọ), awọn lilo ti bulọọgi-afọju iho, sin Iho ọna ẹrọ, a Circuit ọkọ pẹlu jo ga pinpin iwuwo. Nitori idagbasoke ilọsiwaju ti imọ-ẹrọ fun awọn ibeere itanna ifihan iyara giga, igbimọ Circuit gbọdọ pese iṣakoso impedance pẹlu awọn abuda ac, agbara gbigbe igbohunsafẹfẹ giga, dinku itankalẹ ti ko wulo (EMI) ati bẹbẹ lọ. Lilo Stripline, Microstrip be, apẹrẹ ọpọ-Layer di pataki. Lati le dinku iṣoro didara ti gbigbe ifihan agbara, ohun elo idabobo pẹlu iye iwọn dielectric kekere ati iwọn attenuation kekere yoo gba. Lati le baamu miniaturization ati titobi ti awọn paati itanna, iwuwo ti igbimọ Circuit yoo pọ si nigbagbogbo lati pade ibeere naa.

HDI (ga iwuwo interconnection) Circuit ọkọ maa pẹlu lesa afọju iho ati darí afọju iho;
Ni gbogbogbo nipasẹ iho ti a sin, iho afọju, iho agbekọja, iho staggered, iho ti a fi sinu agbelebu, nipasẹ iho, iho afọju ti o kun electroplating, laini tinrin aafo kekere, microhole awo ati awọn ilana miiran lati ṣaṣeyọri itọsi laarin awọn ipele inu ati ita, nigbagbogbo afọju. sin opin ni ko tobi ju 6mil.

HDI Circuit ọkọ ti pin si orisirisi ati eyikeyi Layer interconnection

Ilana HDI akọkọ: 1+N+1 (titẹ lẹmeji, lesa lẹẹkan)

Ilana HDI-keji: 2+N+2 (titẹ fun awọn akoko 3, lesa fun awọn akoko 2)

Ilana HDI kẹta: 3+N+3 (titẹ awọn akoko 4, lesa awọn akoko 3) Ilana kẹrin

Eto HDI: 4+N+4 (titẹ awọn akoko 5, lesa 4 igba)
