He aha ka waihoʻoluʻu o ka papa PCB, e like me ka inoa e hōʻike nei, ke loaʻa iā ʻoe kahi papa PCB, ʻoi aku ka intuitively hiki iā ʻoe ke ʻike i ka waihoʻoluʻu ʻaila ma ka papa, ʻo ia ka mea a mākou e kuhikuhi ai i ke kala o ka papa PCB. ʻO nā kala maʻamau ka ʻōmaʻomaʻo, ka uliuli, ka ʻulaʻula a me ka ʻeleʻele, etc. E kali.

1. ʻO ka'ōmaʻomaʻo'ōmaʻomaʻo ka mea i hoʻohana nuiʻia,ʻo ka lōʻihi loa i ka mōʻaukala, a me ka liʻiliʻi loa i ka mākeke o kēia manawa, no laila, hoʻohanaʻia ka'ōmaʻomaʻo e ka nui o nā mea hana e like me ke kala nui o kā lākou huahana.

2. Ma lalo o nā kūlana maʻamau, pono e hele ka huahana papa PCB holoʻokoʻa i ka papa hana a me nā kaʻina SMT i ka wā o ka hana hana. I ka hanaʻana i ka papa, he nui nā kaʻina hana e pono e hele i loko o ka lumi melemele, no ka mea, aia ka'ōmaʻomaʻo i ka melemele Uaʻoi aku ka maikaʻi o ka hopena o ka lumi māmā ma mua o nā kala'ē aʻe, akā,ʻaʻole kēia ke kumu nui.

Ke kūʻai aku i nā ʻāpana i SMT, pono e hele ka PCB i nā kaʻina hana e like me ka solder paste a me ka patch a me ka hōʻoia AOI hope loa. Pono kēia mau kaʻina hana i ka hoʻonohonoho optical a me ka calibration. ʻOi aku ka maikaʻi o ke kala ʻōmaʻomaʻo no ka ʻike ʻana i ka mea kani.

3. ʻO nā kala PCB maʻamau he ʻulaʻula, melemele, ʻōmaʻomaʻo, uliuli a ʻeleʻele. Eia nō naʻe, ma muli o nā pilikia e like me ke kaʻina hana, ʻo ke kaʻina o ka nānā ʻana i ka maikaʻi o nā laina he nui e hilinaʻi i ka nānā ʻana a me ka ʻike ʻana o nā limahana (ʻoiaʻiʻo, hoʻohana ʻia ka hapa nui o ka ʻenehana hoʻokolohua lele). Ke nānā mau nei nā maka i ka papa ma lalo o ka mālamalama ikaika. He hana luhi loa keia. ʻO ka'ōlelo pili,ʻo ka'ōmaʻomaʻo ka meaʻino loa i nā maka, no laila, hoʻohana ka hapa nui o nā mea hana ma ka mākeke i nā PCB'ōmaʻomaʻo.

4. ʻO ke kumu o ka uliuli a me ka ʻeleʻele, ʻo ia ka mea i hoʻopaʻa ʻia me nā mea e like me ka cobalt a me ke kalapona, i loaʻa kekahi mau uila uila, a hiki mai nā pilikia pōkole i ka wā e paʻa ka mana. Eia kekahi, pili kaiapuni nā PCB ʻōmaʻomaʻo, a ma nā wahi wela kiʻekiʻe Ke hoʻohana ʻia i ka waena, ʻaʻole e hoʻokuʻu ʻia ke kinoea ʻawaʻawa.

Aia kekahi helu liʻiliʻi o nā mea hana ma ka mākeke e hoʻohana i nā papa PCB ʻeleʻele. ʻO nā kumu nui o kēia mau kumu ʻelua:

Nānā kiʻekiʻe-hope;
ʻAʻole maʻalahi ka papa ʻeleʻele e ʻike i ka wili, e lawe mai i kahi pae paʻakikī i ka papa kope;

I kēia manawa, ʻo ka hapa nui o nā papa i hoʻokomo ʻia i ka Android he PCB ʻeleʻele.

5. Mai ka waena a me ka hopena o ke kenekulia hope, ua hoʻomaka ka ʻoihana e hoʻolohe i ke kala o nā papa PCB, no ka mea, ua hoʻohana nā mea hana mua he nui i nā ʻōmaʻomaʻo PCB papa kala no nā ʻano papa kiʻekiʻe. E manaʻoʻiʻo mālie ʻo PCB Inā ʻōmaʻomaʻo ke kala, pono ke kiʻekiʻe.
