ʻIke kikoʻī

He mea nui ka mānoanoa o nā mea no ke kūkulu ʻana i FR4 PCBS. Ana ʻia ka mānoanoa ma ʻīniha, e like me nā kaukani, ʻīniha, a i ʻole nā ​​milimita. Aia kekahi mau mea e noʻonoʻo ai i ke koho ʻana kahi mea FR4 no kāu PCB. ʻO nā ʻōlelo aʻoaʻo aʻe  maʻalahi i kāu kaʻina koho:

Double-Sided-PCB (3)

1. Koho i nā mea FR4 lahilahi no ke kūkulu ʻana i nā panela me nā kaohi ākea. Hiki i nā mea lahilahi ke kākoʻo i nā ʻaoʻao laulā e pono ai e kūkulu i ka hāmeʻa, e like me nā lako Bluetooth, nā mea hoʻopili USB, a pēlā aku. Kūpono ʻia lākou no nā papahana nui kahi e makemake ai nā ʻenekini e nānā i nā hoʻolālā mālama ākea.

 

2. kūpono nā mea FR4 lahilahi no nā noi e koi ana i ka loli. ʻO kahi laʻana, kūpono ka hoʻohana ʻana i nā mea lahilahi no ka PCB kaʻa a me ka lāʻau lapaʻau no ka mea ʻo kēia PCB

pono e kūlou mau.

Hōʻalo i ke koho ʻana i nā mea lahilahi no kahi hoʻolālā PCB i hoʻoulu ʻia, no ka mea hoʻonui kēia i ka makaʻu o ka poino a i ʻole ka haki ʻana o ka papa kaapuni.

 

3. Hiki i ka mānoanoa o nā mea ke hoʻopili i ke kaupaona o ka papa kaapuni i paʻi ʻia a hiki paha ke hoʻopili i ka hoʻohālikelike o nā mea. ʻO ke kumu o kēia ka mea FR4 lahilahi e hana maʻalahi i ka hana ʻana i nā papa kaapuni māmā, a laila e alakaʻi i nā uila uila. ʻOluʻolu a maʻalahi hoʻi e lawe i kēia mau huahana māmā.

I ka wā e hōʻalo ai i ka hoʻohana ʻana i nā mea FR4, ʻaʻole koho pono nā mea FR4 inā koi kāu noi i kekahi o kēia mau mea: Kūlana wela maikaʻi loa: ʻaʻole koi ʻia ʻo FR4 inā e hoʻohana ʻia ʻo PCB i nā wahi wela kiʻekiʻe. ʻO kahi laʻana, ʻaʻole koho nā mea FR4 i kahi koho kūpono no PCB i nā polokalamu aerospace.

Welds free alakaʻi: Inā makemake kāu mea kūʻai aku i kahi PCB e kūlike ana me RoHS, pono e hoʻohana i nā kuʻina alakaʻi ʻole. I ka soldering ʻole o ke kēpau, hiki i ka mahana o ka reflux ke piʻi i kahi kiʻekiʻe o 250 ° C, a ma muli o ke kūpaʻa haʻahaʻa o ka mahana, nā mea FR4.

ʻaʻole hiki ke kū aʻe.

Hōʻailona alapine kiʻekiʻe: Ke hōʻike ʻia i ka hōʻailona alapine kiʻekiʻe, ʻaʻole hiki i ka pā FR4 ke mālama i ka impedance paʻa. A ʻo kahi hopena, kū nā fluctuations a hiki i ka hopena o ka hōʻailona.

 

Ma muli o ko lākou kaulana a me ka hoʻohana ākea, i kēia lā maʻalahi ka loaʻa o nā mea FR4 PCB ma ka mākeke me nā ʻano kikoʻī a me nā hana. ʻO ia mau koho waiwai i kekahi manawa e paʻakikī nā koho. I kēia hihia, he mea nui e kūkākūkā i kāu mau koi me ka mea hana.
