He aha nāPCBnā kūlana nānā hiʻohiʻona?
1. Packaging: colorless air bag vacuum packaging, with desiccant inside, tightly packed
2. Pa'i kilika: 'O ka pa'i kilika o nā hua'ōlelo a me nā hō'ailona ma ka ili o ka PCB pono e maopopo a maopopo, a pono ke kala e ho'okō i nā rula, me ka'ole o ka pa'i pinepine'ana, ka nele i ka pa'i'ana, ka pa'i nui, ka ho'okae kūlana, a kuhi hewa.
3. Ka ʻili o ka papa lihi: E nānā inā he mau ʻeleʻele, ʻokoʻa, nā lua, nā koena o ka pā ma ka PCB;inā paha i ʻoki ʻia ka ʻili o ka papa a ʻike ʻia i ka substrate;Aia nā papa, etc.
4. Conductors: ʻAʻohe kaapuni pōkole, kaapuni hāmama, ke keleawe i ʻike ʻia i loko o ka mea hoʻokele, ka pahu keleawe e lana ana, nā wili hoʻohui, a me nā mea ʻē aʻe. Manalima gula: luster, bumps/bubbles, stains, copper foil floating, surface coating, burrs, plating adhesion, etc.
5. Puka: E nānā i ka pūʻulu mua o nā PCB maikaʻi e nānā inā aia nā lua wili i nalo, nā lua wili he nui, nā puka i ālai ʻia, a me ka wehe ʻana o ka puka.Solder mask: Hiki iā ʻoe ke hoʻohana i ka wai holoi papa e holoi iā ia i ka wā o ka nānā ʻana e nānā i kona pili ʻana, e nānā inā hāʻule paha ia, inā he ʻūlū, inā paha he hanana hoʻoponopono, a me nā mea ʻē aʻe. .
6. Mākaʻikaʻi: ʻano, wahi kuhikuhi, mana hoʻohālike, helu ahi / UL.maʻamau, mokuna hoʻāʻo uila, papa inoa o ka mea hana, lā hana, etc.
7. Ka nui ana: e ana ina paha ka nui maoli o ka PCB e hiki mai ana e like me ka mea i hoakakaia ma ke kauoha.
ʻO ka nānā ʻana i ka warpage a i ʻole curvature:
8. Solderability ho'āʻo: E lawe i kekahi hapa o ka PCB no ka maoli soldering, a nana ina i na apana hiki ke maʻalahi soldered.
