Mea kūʻai/mea hoʻolako Metal Dome Switch
ʻOhi ʻōpala
ʻO nā papa Guozi ka mea maʻamau i ka pihi shrapnel
Hana ʻia ka ʻāpana pihi (ʻike mau ʻia ʻo ka dome metala, snap dome) me nā mea ʻoi loa ka lahilahi (0.05mm-0.1mm mānoanoa) a me ka mānoanoa nui (ʻoi aku ka paʻakikī) mea kila 301 a i ʻole 304.ʻO ke pihi shrapnel kahi mea nui o ka hoʻololi.
Ka inoa Pākē: Puka puʻupuʻu
ʻIke ʻia hoʻi: Nā ʻāpana ipu
Mea: Ke kila kila 301 a i ʻole 304
Anawaena: 3mm a 20mm
Hoʻohana nui ʻia ka pihi shrapnel i nā hoʻololi membrane, nā hoʻololi pili dome, nā papa PCB, nā papa FPC, nā mea lapaʻau a me nā huahana ʻē aʻe.ʻO ke kumu hana o ka pihi shrapnel: Aia ka pihi shrapnel ma ka pihi membrane ma ka ʻaoʻao conductive o ka papa PCB (ka hapa nui ma luna o nā manamana gula ma ka papa kaapuni).Ke paʻi ʻia, concave ke kiko waena o ka shrapnel a pā i ke kaapuni ma ka PCB., No laila ke hana ʻana i ka loop, ke hele nei ka manawa, a hiki i ka huahana holoʻokoʻa ke hana maʻamau.
ʻO ka maʻamau, hiki ke hoʻokaʻawale ʻia nā puʻupuʻu pihi maʻamau i nā ʻāpana metala poepoe, nā ʻāpana metala keʻa, nā ʻāpana metala triangular, a me nā shrapnel metala oval e like me ko lākou ʻano like ʻole.ʻO ke anawaena mai 3mm a 20mm, a ʻo ka ikaika mai 100g a 600gf.E like me ka ili electroplating lapaau, hiki ke maheleia i: gula plating, nickel plating, kala plating, malamalama ili a pela aku.ʻElua ʻano o ka electroplating ʻaoʻao hoʻokahi a me ka electroplating ʻaoʻao ʻelua.
