Pono nā mea maloʻo! ʻO ka hoʻohālikelike pale PCB ʻike i ka nui

Hiki iā mākou ke ʻike i ka pale ma nā PCBS he nui, ʻoi aku hoʻi i nā mea uila uila e like me nā kelepona paʻalima. Ua uhi ʻia ka PCB o ke kelepona me nā pale.

Loaʻa ʻia nā uhi pale i ka PCBS kelepona paʻa, no ka mea, he ʻano kaʻa kaʻa kamaʻilio uea ʻole nā ​​kelepona paʻa, e like me GPS, BT, WiFi, 2G/3G/4G/5G, a me kekahi mau kaapuni analog koʻikoʻi a me nā kaapuni mana hoʻololi DC-DC. pono e hoʻokaʻawale ʻia me nā uhi pale. Ma kekahi ʻaoʻao, ʻaʻole lākou e hoʻopilikia i nā kaapuni ʻē aʻe, a ma ka ʻaoʻao ʻē aʻe, pale lākou i nā ʻāpana ʻē aʻe e hoʻopilikia iā lākou iho.

ʻO kēia kekahi o nā hana o ka pale ʻana i ka hoʻopili electromagnetic; ʻO kekahi hana ʻē aʻe o ka pale e pale aku i nā kuʻi. E māhele ʻia ʻo PCB SMT i nā papa he nui. ʻO ka maʻamau, pono e hoʻokaʻawale ʻia nā pā e pili ana i mea e pale aku ai i kahi hoʻokuʻi kokoke i ka wā o ka hoʻāʻo ʻana a i ʻole ka halihali ʻana.

ʻO nā mea maka o ka pale he keleawe keʻokeʻo keʻokeʻo, ke kila kila, tinplate, etc. I kēia manawa, hoʻohana ʻia ka hapa nui o nā pale i ke keleawe keʻokeʻo.

Hōʻike ʻia ke keleawe keʻokeʻo e kahi hopena pale pale maikaʻi ʻole, palupalu, ʻoi aku ke kumukūʻai ma mua o ke kila kila, maʻalahi i ka tin; He maikaʻi ka hopena pale kila kila, ikaika kiʻekiʻe, kumu kūʻai kūpono; Eia nō naʻe, paʻakikī ke kī (aʻole hiki ke hana ʻia me ka ʻole o ka hoʻomaʻamaʻa ʻana i ka ʻili, a hoʻomaikaʻi ʻia ma hope o ka hoʻopaʻa ʻana i ka nickel, akā ʻaʻole naʻe i kūpono i ka pā); ʻO ka hopena pale tinplate ka mea ʻino loa, akā maikaʻi ka tin a ʻoi aku ke kumukūʻai.

Hiki ke hoʻokaʻawale ʻia ka pale i paʻa a hiki ke wehe.

Hoʻokahi ʻāpana pale pale paʻa i kapa ʻia he ʻāpana hoʻokahi, pili pololei ʻo SMT i ka PCB, ʻōlelo Pelekane maʻamau i kapa ʻia ʻo Shielding Frame.

ʻO ka pale ʻelua ʻāpana hiki ke wehe ʻia i kapa ʻia ʻo ka pale ʻelua ʻāpana, a hiki ke wehe pololei ʻia ka pale ʻelua me ke kōkua ʻole o kahi mea hana wela. ʻOi aku ka maikaʻi o ke kumukūʻai ma mua o ka ʻāpana hoʻokahi, ua wili ʻia ka SMT ma ka PCB, i kapa ʻia ʻo Shielding Frame, ʻo ka mea i kapa ʻia ʻo Shielding Cover, pololei ma ka Shielding Frame, maʻalahi e wehe, ʻo ka mea maʻamau ka inoa o ka Frame i kapa ʻia ʻo shielding frame, ka mea i luna. Kapa ʻia ka uhi uhi pale. Manaʻo ʻia ka pahu e hoʻohana i ke keleawe keʻokeʻo, ʻoi aku ka maikaʻi o ka tin; Hiki ke hana ʻia ka uhi me ka tinplate, ʻoi aku ka maikaʻi. Hiki ke hoʻohana ʻia nā ʻāpana ʻelua i ka wā mua o ka papahana e hoʻomaʻamaʻa i ka debugging, e kali no ka paʻa o ka debugging hardware, a laila e noʻonoʻo i ka hoʻohana ʻana i ka ʻāpana hoʻokahi e hōʻemi i nā kumukūʻai.
