Kodi ma vias ang'onoang'ono, akhungu ndi ma vias okwiriridwa mu HDI PCB Boards ndi chiyani?

Ma board osindikizira a High-density interconnect (HDI) (PCBs) asintha makampani opanga zamagetsi popangitsa kuti pakhale zida zazing'ono, zopepuka komanso zogwira mtima kwambiri.Ndi miniaturization yosalekeza ya zida zamagetsi, mabowo achikhalidwe sakhalanso okwanira kukwaniritsa zosowa zamakono. Izi zachititsa kuti ntchito microvias, akhungu ndi kukwiriridwa vias HDI PCB Board. Mu blog iyi, Capel adzayang'ana mozama pa mitundu iyi ya vias ndi kukambirana kufunika kwawo HDI PCB mapangidwe.

1. Micropore:

Ma Microholes ndi mabowo ang'onoang'ono okhala ndi mainchesi 0.006 mpaka 0.15 (0.15 mpaka 0.4 mm). Amagwiritsidwa ntchito popanga kulumikizana pakati pa zigawo za HDI PCBs. Mosiyana vias, amene kudutsa gulu lonse, microvias pang'ono kudutsa pamwamba wosanjikiza. Izi zimapangitsa kuti pakhale kachulukidwe kachulukidwe kake komanso kugwiritsa ntchito bwino malo a board, kuwapangitsa kukhala ofunikira pakupanga zida zamagetsi zamagetsi.

Chifukwa cha kukula kwawo kochepa, ma micropores ali ndi ubwino wambiri. Choyamba, amathandizira kuwongolera kwazinthu zowoneka bwino monga ma microprocessors ndi ma memory chips, kuchepetsa kutalika kwa trace ndikuwongolera kukhulupirika kwa ma siginecha. Kuphatikiza apo, ma microvias amathandizira kuchepetsa phokoso lazizindikiro ndikuwongolera mawonekedwe amtundu wothamanga kwambiri popereka njira zazifupi. Zimathandizanso kuti pakhale kayendetsedwe kabwino ka kutentha, chifukwa amalola kuti matenthedwe azitha kuikidwa pafupi ndi zigawo zopangira kutentha.

2. Bowo lakhungu:

Vis akhungu ndi ofanana ndi microvias, koma amachoka wosanjikiza akunja kwa PCB kwa zigawo chimodzi kapena zingapo zamkati za PCB, kulumpha zigawo zina wapakatikati. Vias izi amatchedwa "akhungu vias" chifukwa zimaonekera kokha kuchokera mbali imodzi ya bolodi. Vis akhungu zimagwiritsa ntchito kulumikiza wosanjikiza akunja a PCB ndi moyandikana wosanjikiza wamkati. Poyerekeza ndi mabowo, imatha kusintha kusinthasintha kwa mawaya ndikuchepetsa kuchuluka kwa zigawo.

Kugwiritsa ntchito ma vias akhungu ndikofunikira kwambiri pamapangidwe apamwamba kwambiri pomwe zopinga za danga ndizofunikira. Pochotsa kufunikira kobowola m'mabowo, akhungu kudzera pama siginecha osiyana ndi ndege zamagetsi, kukulitsa kukhulupirika kwa ma siginecha ndikuchepetsa kusokoneza kwamagetsi (EMI). Amakhalanso ndi gawo lofunikira pochepetsa makulidwe onse a HDI PCBs, motero zimathandizira kuti zida zamakono zamagetsi ziziwoneka bwino.

3. Bowo lokwiriridwa:

Anakwiriridwa vias, monga dzina likusonyeza, ndi vias kuti kwathunthu zobisika mkati mwa zigawo za PCB. Vias izi sizimawonjezera zigawo zilizonse zakunja ndipo motero "kuikidwa m'manda". Nthawi zambiri amagwiritsidwa ntchito m'mapangidwe ovuta a HDI PCB ophatikiza magawo angapo. Mosiyana ndi ma microvias ndi ma vias akhungu, vias m'manda siziwoneka kuchokera mbali zonse za bolodi.

Ubwino waukulu wa vias wokwiriridwa ndi kuthekera kopereka kulumikizana popanda kugwiritsa ntchito zigawo zakunja, kupangitsa kuti kachulukidwe apamwamba azidutsa. Mwa kumasula danga lamtengo wapatali pazigawo zakunja, ma vias oikidwa m'manda amatha kukhala ndi zigawo zina ndi kufufuza, kupititsa patsogolo ntchito za PCB. Zimathandizanso kuwongolera kasamalidwe ka matenthedwe, chifukwa kutentha kumatha kutayidwa bwino kudzera mu zigawo zamkati, m'malo mongodalira pazigawo zakunja.

Pomaliza,Vis yaying'ono, vias akhungu ndi vias m'manda ndi zinthu zofunika HDI PCB bolodi kamangidwe ndi kupereka osiyanasiyana ubwino kwa miniaturization ndi mkulu kachulukidwe zipangizo zamagetsi.Ma Microvias amathandizira kuyenda kowuma komanso kugwiritsa ntchito bwino malo a board, pomwe njira zakhungu zimapereka kusinthasintha ndikuchepetsa kuwerengera kosanjikiza. Njira zokwiriridwa zimachulukitsa kachulukidwe kanjira, kumasula zigawo zakunja kuti zikhazikike ndikuwonjezera kuwongolera kwamafuta.

Pamene makampani zamagetsi akupitiriza kukankhira malire a miniaturization, kufunikira kwa vias izi HDI PCB Board mapangidwe okha kukula. Mainjiniya ndi opanga amayenera kumvetsetsa zomwe angathe komanso zomwe angakwanitse kuti azigwiritse ntchito moyenera ndikupanga zida zamagetsi zomwe zimakwaniritsa zomwe zikuchulukirachulukira zaukadaulo wamakono.Shenzhen Capel Technology Co., Ltd ndiwopanga odalirika komanso odzipereka a HDI osindikizidwa matabwa ozungulira. Pokhala ndi zaka 15 zachidziwitso cha polojekiti komanso luso lamakono lopitirirabe, amatha kupereka mayankho apamwamba omwe amakwaniritsa zofunikira za makasitomala. Kugwiritsa ntchito kwawo chidziwitso chaukadaulo chaukadaulo, luso lazotsogola, ndi zida zapamwamba zopangira ndi makina oyesera zimatsimikizira zinthu zodalirika komanso zotsika mtengo. Kaya ndi prototyping kapena kupanga misa, gulu lawo lodziwa zambiri la akatswiri a komiti yoyang'anira dera ladzipereka kuti lipereke mayankho aukadaulo a HDI a PCB a projekiti iliyonse.
