Ka hopena o ke kaiapuni i ka hana kapasitor

I. Ka wela ambient
1. ʻO ka wela kiʻekiʻe
ʻO ka mahana hana kiʻekiʻe loa a puni ka capacitor he mea nui loa ia no kāna noi.ʻO ka piʻi ʻana o ka mahana e hoʻolalelale i nā hopena kemika a me ka electrochemical, a maʻalahi ka mea dielectric i ka makahiki.Ke emi nei ke ola o ka capacitor me ka piʻi ʻana o ka mahana.Hoʻololi ka capacitance me ka piʻi ʻana o ka mahana ma muli o ka pilina ma waena o ka dielectric mau a me ka mahana, me ka coefficient mahana maikaʻi, ʻo ia hoʻi, piʻi ka mana me ka mahana, me ka emi ʻana o ka coefficient wela maikaʻi me ka mahana.
Ke piʻi aʻe ka mahana, piʻi ka hana uila, no laila ke emi nei ke kūpaʻa insulation me ka piʻi ʻana o ka mahana.Hoʻemi pū ka ikaika dielectric me ka piʻi ʻana o ka mahana, no laila pono e hoʻemi ʻia ka volta hana i ka wā e hoʻonui ʻia ai ka mahana lawelawe kiʻekiʻe.Hoʻonui ka wela kiʻekiʻe i ka oxidation metala, piʻi ke kūʻē pili, piʻi ke kūʻē a piʻi ka poho.

2. ʻO ka wela haʻahaʻa
Lilo ka mea i palupalu, haki ka epoxy resin a nalowale kona hopena pale.Hoʻohaʻahaʻa ʻia ka hana uila o ka capacitor e ka infiltration moisture.

3. Ka hopena wela kiʻekiʻe a haʻahaʻa
Rapid thermal hoʻonui a me ka contraction hana i loko stress, hana alternating condensation, maloo a me ka evaporation, no laila, i ka encapsulation papa māwae, māwae alakai i ka wai mahu infiltration, accelerate ka hana o ka capacitor deteriorates.
 
II.Kaiapuni haʻahaʻa

1. ʻO ka haʻahaʻa kiʻekiʻe
ʻO ka wai mahu condenses ma luna o ka ili o ka capacitor, a omo, no laila, i ka insulation kū'ē o ka capacitor emi, a aia ka leakage a me ka arc lele.Hoʻonui ka dielectric mau a piʻi ka poho dielectric.Ke komo ka mahu wai i loko o ka papa metala o loko o ka capacitor, e emi ana ka mana a e hoʻonui ka poho.

2. Hoʻololi i ka wela a me ka wai
Hoʻopili ʻia ka mahu wai a hoʻopuehu ʻia ma ka ʻili o ka capacitor.Hiki i ka hanu ʻana a me ka condensation o ka hoʻomehana ke hoʻolalelale i ka mahu wai e komo i loko o ka capacitor a e hoʻohaʻahaʻa i ka hana o ka capacitor e like me ka mea i ʻōlelo ʻia ma luna.
Ma ka haʻahaʻa pili like, i ka piʻi ʻana o ka mahana, piʻi ka nui o nā molekole wai a hoʻonui ʻia ka hoʻokumu ʻana o nā āpau mole.Hiki i nā molekule wai ke komo i kēia mau āpau mai ka ea a puni a no laila e komo i loko o ka waena.
Ma ka haʻahaʻa haʻahaʻa hoʻokahi, ʻoi aku ka haʻahaʻa o ka mahana, ʻoi aku ka kiʻekiʻe o ka haʻahaʻa pili, ʻoi aku ka nui o ka moisture e komo ai ka capacitor.

III.Kaiapuni ikaika
ʻO ka vibration, ka hopena a me ka wikiwiki ka mea koʻikoʻi koʻikoʻi, hiki ke hoʻopōʻino a hōʻino paha ka capacitor e kamīkini SMTa me nā mīkini ʻē aʻe, a hoʻololi ka capacitance ma muli o ka hoʻololi liʻiliʻi o ka hoʻolālā capacitor.Eia kekahi, hiki ke kumu i ka haki alakaʻi, ka pilina maikaʻi ʻole a me nā mea ʻē aʻe.

IV.Kaiapuni puʻe haʻahaʻa
Hoʻohana ʻia nā Capacitors ma nā wahi kiʻekiʻe.Me ka piʻi ʻana o ke kiʻekiʻe, e emi ana ke kaomi o ka ea a me ka emi ʻana o ka pale uila o ka ea.E hana ka capacitor i ka arc a me ka corona phenomenon, a e emi iho ka ikaika o ka capacitor.Eia kekahi, paʻakikī ka ea lahilahi i ka wela.E piʻi ka piʻi ʻana o ka wela o ka capacitor.

ʻO Zhejiang NeoDen Technology Co., LTD., i hoʻokumu ʻia i ka makahiki 2010, he mea hana loea i ka mīkini koho SMT a me kahi mīkini, reflow umu, mīkini paʻi stencil, laina hana SMT a me nā huahana SMT ʻē aʻe.Loaʻa iā mākou kā mākou hui R & D a me kā mākou hale hana ponoʻī, e hoʻohana ana i kā mākou R&D ʻike waiwai ponoʻī, hana hoʻomaʻamaʻa maikaʻi, lanakila i ka inoa nui mai nā mea kūʻai aku o ka honua. i Innovation, Diversity and Sustainability e hōʻoia i ka loaʻa ʻana o ka automation SMT i kēlā me kēia mea hobbyist ma nā wahi āpau.
