1. Nā kumu kumu o ka wrinkling ʻO nā kumu nui e wīwī ai i ka ʻāpana keleawe ma nā kaʻina R2R: ʻAʻohe kaulike: ʻO ke koʻikoʻi koʻikoʻi kūloko ma muli o nā gradients. Kūlike ʻole CTE: Copper (17 ppm/°C) vs. PI (35 ppm/°C) ʻokoʻa hoʻonui. ...

1. Nā Paʻakikī Koʻikoʻi Nā ʻiʻo mālohi loa (

ʻO kahi ʻōnaehana ʻike maka opitika (AOI) pūnaewele he mea pono loa i ka hana PCB a me ka hui uila, ʻoi aku ka nui no ka ʻike ʻana i nā laina laina ma lalo o 10μm. Aia ma lalo iho kahi wehewehe kikoʻī o ka hoʻokō ʻana i kēia me ka hoʻohana ʻana i kahi ʻōnaehana AOI pūnaewele: ...

1. Nā kumu a me nā pono ʻO nā lasers Femtosecond (10-15s pulse width) hiki i ka nonlinear absorption ma o: Multi-photon ionization (MPI) Avalanche ionization (AI) Key pōmaikaʻi: Near-zero HAZ Sub-micron precision (min. 1μm puka) ...

He mea koʻikoʻi ka mālama ʻana i ka resonance frequency o RF PCB no ka hōʻoia ʻana i ka hana kaapuni a me ka hōʻailona hōʻailona. Ma ka hoʻonui ʻana ma o ka simulation, hiki i nā mea hoʻolālā ke wānana a hoʻoponopono i nā alapine resonance i ka wā o ka hoʻolālā, hoʻomaikaʻi i ka pono a me ka huahana q...

1. Nā Kuʻuna a me ka Hoʻohana ʻana o ka Acoustic Emission (AE) Acoustic Emission ʻike i nā hawewe koʻikoʻi elastic elastic kiʻekiʻe (20 kHz–1 MHz) i hoʻokuʻu ʻia i ka wā o ka deformation a i ʻole ka hiki ʻole. Ma nā papa HDI, hoʻolaha ʻia ka micro-crack (mai ka thermal/mechanical stre...

1. Wehewehena a me ka hana hana PIM e pili ana i ka hana ʻana o nā ʻāpana alapine hou i ka wā e hui pū ai nā hōʻailona ʻelua a ʻoi aʻe paha i loko o nā ʻāpana passive (e laʻa, nā mea hoʻohui, antennas, PCB traces) ma muli o nā ʻano laina ʻole. ʻO kēia mau nonlinearities ma ...

1. Ka hope a me nā pilikia kumu I ka hana ʻana o ka PCB multilayer, hoʻopaʻa ka lamination i nā cores i loko, prepreg, a me ka foil keleawe ma lalo o ka wela / kaomi. Nā mea hoʻohaumia (ʻaila, oxides, lepo) ma luna o nā ʻili ma mua o ka lamination kumu: Nawaliwali ka pili o ka maka: Ke alakaʻi nei i ka delami...
