HDI Circuit Board vs. Regular PCB Board: Kuwulula Kusiyana

Pazinthu zamagetsi, matabwa ozungulira amagwira ntchito yofunika kwambiri pogwirizanitsa zigawo zosiyanasiyana ndikuonetsetsa kuti chipangizocho chikugwira ntchito bwino. Kwa zaka zambiri, kupita patsogolo kwaukadaulo kwapangitsa kuti pakhale mapangidwe ovuta komanso ophatikizika a board board. Kupita patsogolo kotereku ndikukhazikitsa ma board a HDI (High Density Interconnect).Mu positi iyi, tiwona kusiyana pakati pa ma board a HDI ndi ma board okhazikika a PCB (Printed Circuit Board).

Tisanafufuze zomwe zili zenizeni, tiyeni timvetsetse mfundo zazikuluzikulu zama board a HDI ndi ma board a PCB.PCB ndi mbale yathyathyathya yopangidwa ndi zinthu zopanda ma conductive zokhala ndi njira zoloweramo. Njirazi, zomwe zimatchedwanso kuti traces, zimakhala ndi udindo wonyamula zizindikiro zamagetsi pakati pa zigawo zosiyanasiyana pa bolodi la dera. Ma board a PCB amagwiritsidwa ntchito kwambiri pazida zosiyanasiyana zamagetsi, kuyambira mafoni am'manja ndi laputopu kupita ku zida zamankhwala ndi makina amagalimoto.

Ma board a HDI, Komano, ndi mitundu yapamwamba kwambiri ya matabwa a PCB.Ukadaulo wa HDI umalola kuti kachulukidwe wozungulira kwambiri, mizere yocheperako, ndi zida zocheperako. Izi zimathandiza kupanga zida zazing'ono, zopepuka komanso zolimba kwambiri. Ma board ozungulira a HDI nthawi zambiri amagwiritsidwa ntchito pamapulogalamu omwe amafunikira kuthamanga kwambiri, magwiridwe antchito abwino, ndi miniaturization, monga mafoni apamwamba kwambiri, mapiritsi, ndi zida zam'mlengalenga.

Tsopano tiyeni tiwone kusiyana pakati pa matabwa a HDI ndi matabwa wamba a PCB:

Kachulukidwe Wozungulira ndi Kuvuta:

Chosiyanitsa chachikulu pakati pa matabwa ozungulira a HDI ndi matabwa okhazikika a PCB ndi kachulukidwe wadera. Ma board a HDI ali ndi kachulukidwe kakang'ono kwambiri chifukwa chaukadaulo wawo wapamwamba wopanga komanso malamulo apadera opangira. Poyerekeza ndi matabwa achikhalidwe a PCB, omwe nthawi zambiri amakhala ndi zigawo zochepa, matabwa a HDI amakhala ndi zigawo zambiri, kuyambira 4 mpaka 20 zigawo. Amalola kugwiritsa ntchito zigawo zowonjezera ndi ma vias ang'onoang'ono, kulola kuti zigawo zambiri ziphatikizidwe mu malo ang'onoang'ono. Komano, ma board wamba a PCB amachepetsedwa ndi mapangidwe awo osavuta komanso zigawo zochepa, zomwe zimapangitsa kuti kachulukidwe wadera atsike.

Ukadaulo wa Micropore:

HDI matabwa dera ambiri ntchito luso microvia, kuphatikizapo vias akhungu, vias m'manda ndi vias zakhala zikuzunza m'miyoyo. Vis awa amapereka kugwirizana mwachindunji pakati pa zigawo zosiyanasiyana, kuchepetsa pamwamba m'dera chofunika wodutsa ndi maximizing malo zilipo. Mosiyana ndi izi, matabwa wamba PCB nthawi zambiri amadalira luso kudzera m'dzenje, amene kuchepetsa mphamvu zawo kuti akwaniritse kachulukidwe mkulu dera, makamaka mu angapo wosanjikiza mapangidwe.

Kukula kwazinthu:

Ma board ozungulira a HDI nthawi zambiri amakhala ndi zida zokhala ndi matenthedwe owonjezera, magetsi, komanso makina. Zidazi zimapereka magwiridwe antchito, kudalirika komanso kulimba, kupanga matabwa a HDI oyenera kufunsira ntchito. Ma board a PCB okhazikika, akadali akugwira ntchito, nthawi zambiri amagwiritsa ntchito zida zoyambira ndipo sangakwaniritse zofunikira pazida zamagetsi zovuta.

Miniaturization:

Ma board ozungulira a HDI adapangidwa kuti akwaniritse zosowa za miniaturization zamagetsi zamagetsi. Njira zopangira zapamwamba zomwe zimagwiritsidwa ntchito m'mabodi a HDI zimalola ma vias ang'onoang'ono (mabowo omwe amalumikiza zigawo zosiyanasiyana) ndi mawonekedwe abwino. Izi zimapangitsa kuti pakhale kuchulukirachulukira kwa magawo pagawo lililonse, zomwe zimapangitsa kupanga zida zazing'ono, zowoneka bwino popanda kusokoneza magwiridwe antchito.

Kukhulupirika kwa ma Signal ndi ntchito zothamanga kwambiri:

Pomwe kufunikira kwa kutumiza kwa data mwachangu komanso kukhulupirika kwa ma siginecha kukukulirakulira, ma board ozungulira a HDI amapereka zabwino zambiri kuposa ma board a PCB wamba. Kuchepetsedwa kudzera ndikutsata makulidwe m'ma board a HDI kumachepetsa kutayika kwa ma sign ndi kusokoneza phokoso, kuwapangitsa kukhala oyenera kugwiritsa ntchito liwilo kwambiri. Ukadaulo wa HDI umalolanso kuphatikizika kwa zinthu zina monga akhungu ndi ma vias okwiriridwa, kupititsa patsogolo magwiridwe antchito komanso kudalirika.

Mtengo wopangira:

Dziwani kuti mtengo kupanga HDI matabwa ozungulira nthawi zambiri apamwamba poyerekeza matabwa wamba PCB. Kuwonjezeka kwa zovuta ndi kuchuluka kwa zigawo kumapangitsa kuti ntchito yopanga zinthu ikhale yovuta komanso iwononge nthawi. Kuphatikiza apo, kugwiritsa ntchito zida zapamwamba komanso zida zapadera kumawonjezera mtengo wonse. Komabe, maubwino ndi kusintha kwa magwiridwe antchito operekedwa ndi ma board a HDI nthawi zambiri kumaposa mtengo wawo wapamwamba, makamaka m'mafakitale omwe kudalirika kwakukulu ndi miniaturization ndizofunikira.

Mapulogalamu ndi maubwino:

Kugwiritsa ntchito HDI circuit board:

Ma board a HDI amagwiritsidwa ntchito kwambiri pazida zamagetsi zophatikizika monga mafoni am'manja, mapiritsi, zida zovala, ndi zida zazing'ono zamankhwala. Kukhoza kwawo kuthandizira magwiridwe antchito apamwamba komanso kufota kwa mawonekedwe kumawapangitsa kukhala oyenera kugwiritsa ntchito izi.

Ubwino wa matabwa a HDI:

- Kuchulukirachulukira kozungulira kumapangitsa kuti pakhale mapangidwe ovuta komanso olemera.
- Kupititsa patsogolo kukhulupirika kwa chizindikiro chifukwa cha kuchepa kwa parasitic capacitance ndi inductance.
- Kutentha kowonjezereka kumatsimikizira kugwira ntchito bwino kwa zigawo zamphamvu kwambiri.
- Mbiri yaying'ono imasunga malo komanso imathandizira mapangidwe opepuka.
- Kuwongolera kukana kugwedezeka, kugwedezeka ndi zinthu zachilengedwe, kuwongolera kudalirika kwa zida zonse.

Powombetsa mkota,kusiyana pakati pa matabwa HDI dera ndi matabwa wamba PCB ndi yaikulu. Ma board ozungulira a HDI amapereka kachulukidwe wapamwamba kwambiri, njira zopangira zida zapamwamba komanso zabwino zamawonekedwe azizindikiro, zomwe zimawapangitsa kukhala abwino kwambiri pazida zamagetsi zamagetsi. Komabe, ma board wamba a PCB amathanso kugwira ntchito pamapulogalamu omwe safuna zovuta kapena miniaturization. Kumvetsetsa kusiyana kumeneku kudzathandiza opanga ndi opanga kuti asankhe bolodi loyenera la dera pazosowa zawo zenizeni, kuonetsetsa kuti ntchito yabwino, yodalirika komanso yogwira ntchito pazida zawo zamagetsi.
