Nā ʻano papa kaapuni like ʻole

ka papa kaapuni i paʻi ʻia a i ʻole PCB ka papa kākoʻo kino ʻoiai e hoʻopili uila ana i nā ʻāpana uila like ʻole o ka ʻōnaehana ākea. Hoʻohana ka papa kaapuni i nā uwila conductive, padding a me nā mea ʻē aʻe e kani mai ka papa keleawe.

Hoʻokahi ʻaoʻao

E like me ka manaʻo o ka inoa, hana ʻia kahi PCB ʻaoʻao hoʻokahi o kahi mea hoʻokahi, ʻike ʻia hoʻi he “substrate.” On top of the base is a thin foil layer made of copper. Hana kēia ma ke ʻano he conductor o nā hōʻailona uila.

ʻO kēia nā ʻano maʻamau o ka PCBS a kaulana loa i ka hana nui ma muli o kā lākou kumu kūʻai haʻahaʻa. Loaʻa pinepine ʻia kēia mau papa i nā pahu kiʻi, nā helu helu a me nā mea lekiō.

Hiki ke loaʻa iā lākou ma nā hoʻolālā pāʻani maʻalahi.

Nā ʻaoʻao ʻelua

Hana like nā papa kaapuni paʻi ʻelua ʻaoʻao e like me nā papa kaapuni paʻi ʻaoʻao hoʻokahi, akā ua hoʻopili ʻia ma waena o nā papa conductive ma nā ʻaoʻao ʻelua. In addition, they are designed to have holes drilled into the plate.

These holes are placed on the board to allow the circuit to be mounted on either side of the PCB or fed through the board. ʻO ka hoʻololi hou a me nā papa conductive e ʻae i nā mea ʻaoʻao ʻelua e hoʻohana ʻia i nā noi ʻoi aku ka holomua.

Loaʻa pinepine ʻia ka PCBS ʻaoʻao ʻelua i nā kelepona paʻalima, nā mīkini kūʻai aku, nā mākaʻikaʻi kaʻa a me nā lako mīkini uila.

ʻAhaʻi nui

ʻO ka hoʻolālā ʻelua ʻaoʻao a hoʻonui i luna. ʻO ka multilayer kahi hōʻiliʻili o nā PCBS ʻaoʻao ʻelua ʻaʻole emi ma lalo o ʻekolu (3). Lawe lākou i ka ʻenehana i hoʻokumu ʻia ma ʻaneʻi a hoʻonui i kā lākou hana hana.

ʻO ka nui a me ka lewa nā pono nui o ka PCBS multi-layer. Hiki iā lākou ke hoʻohana i ka papa multilayer ma kahi o kekahi mau papa.

He ʻāpana koʻikoʻi lākou o nā kaʻa kaʻa kiʻekiʻe no ka mea ʻae ka nui o kā lākou papa i ka hoʻonohonoho conductor kūpono a me ka mana.

Paʻalāki

Rigid PCBS can be single, double, or multi-layered. ʻO ka rigidity e pili ana i ka mea substrate kahi i hana ʻia ai nā papa. When a PCB is rigid, it is, as the name implies, made of materials that resist distortion or deformation.

A very common rigid PCB is the motherboard on a computer. Hoʻolālā ʻia lākou e paʻa a hiki ke hoʻohana ʻia i kahi kūlana a me ke ʻano.

Rigid PCBS benefit from ease of maintenance and ease of use. Loaʻa i nā papahana a pau kahi wahi a hōʻailona maopopo ʻia i ka wā i hoʻolālā ʻia ai. ʻAʻole lākou i kaupalena ʻia i hoʻokahi hoʻolālā a hiki ke hele mai ka papa hoʻokahi a hiki i ka ʻumi (10) papa PCB hoʻolālā.

‘ōlewa

Hana ʻia nā PCBS maʻalahi e like me ka PCBS paʻa, akā hana ʻia me nā mea like ʻole.

Hana ʻia nā papa ʻoʻoleʻa me nā mea paʻa (ʻo ia hoʻi ka paʻa ʻana i ko lākou ʻano) (maʻa mau i kahi hui fiberglass), aʻo ka mea maʻamau i hana ʻia nā papa maʻalahi i ka plastic a i ʻole nā ​​​​mea like.

ʻO ka hoʻololi maoli ka pono nui o ka PCBS maʻalahi. Hiki ke mālama ʻia ke kumu kūʻai ma muli o ko lākou hiki ke “ʻōwili” i nā wahi kahi e hele ai nā papa paʻa.

The main applications of flexible PCBS are in systems that may cause damage to the environment. ʻO kā lākou hoʻolālā e ʻoi aku ka pale ʻana i ka mahana, ka wai, ka corrosion a me nā mea ʻē aʻe e hiki ke hōʻino i nā papa paʻa.

Mixing and soft

Rigid-flexibility Bridges the gap between the two types built on text and graphics, which is most common in mobile phones and digital cameras.

Hoʻopili ʻia kēia mau mea he pūʻulu o nā kaapuni maʻalahi i hoʻopili ʻia i nā papa paʻa he nui. ʻO kēia ka mea e maʻalahi ai ka hoʻolālā, no ka mea, hoʻohui ia i nā mea āpau e pono ai no kēia mau ʻāpana i kahi ʻāpana “hoʻokahi”.

Hiki ke ʻike ʻia ka rigidness a me ka maʻalahi i nā noi lapaʻau.

Aluminum kua

ʻO ka hoʻoheheʻe wela ke kikowaena o ka PCB. Ke noʻonoʻo ʻia ka mahana o ka ʻōnaehana, ʻo ka hoʻohana ʻana i ka PCB backboard alumini ka koho maikaʻi loa, a me nā pono ʻē aʻe.

The structure of the PCB is relatively similar to a standard single or double layer, but the materials used are varied.

ʻOi aku ka lōʻihi a me ke aloha kaiapuni. ʻAʻole ʻawaʻawa ka alumini a maʻalahi loa e hana hou. On top of that, it’s incredibly cheap, it’s one of the cheapest metals in mining, and it’s cheap to make.

Kālā kiʻekiʻe

ʻAʻole i kūkulu ʻia ʻo Hf PCBS i kahi ala hou, no ka laʻana, hoʻohālikelike i hoʻokahi me nā papa he nui, akā e nānā i kahi ʻano hoʻohana. Hiki ke hoʻohana ʻia ka PCBS kiʻekiʻe inā pono e hoʻouna ʻia nā hōʻailona ma nā helu kiʻekiʻe ma mua o 1GHz. They are mainly used in large communication systems.

Nā pōmaikaʻi o ka hoʻohana ʻana i ka PCB

ʻOiai ua loaʻa i kēlā me kēia ʻano o ka papa kona mau pono, he nui nā pōmaikaʻi i ka hoʻohana ʻana i kahi PCB ma ka laulā.

Easy trouble shooting and maintenance

ʻO ka hoʻolālā, a i ʻole “trace,” o ka papa e maʻalahi ke ʻike i nā lako pilikia a hoʻololi iā ia

Remove and reattach to board

Ka pono o: ʻAʻohe pono e kūkulu hou i ke kaapuni holoʻokoʻa i ka wā e hoʻoponopono ai a hoʻololi paha

ʻO ka papa kaapuni kahi hoʻolālā i hana mua ʻia a ʻoi aku ka liʻiliʻi o ka manawa e kūkulu ai ma mua o nā kaapuni kahiko

Halulu haahaa: Hiki i kahi hoʻolālā PCB i hoʻolālā pono ʻia ke alakaʻi i nā ʻāpana uila haʻahaʻa haʻahaʻa, i kapa ʻia ʻo “cross talk.”

Kōkua i ka hoʻopau ʻana i ka walaʻau uila e hiki ke hoʻohaʻahaʻa i ka hana o ka mea hana

pono: No laila, ua hoʻokomo ʻia ka pilina o ka papa me ka uwea keleawe. ʻAʻohe mea pili ʻole a i ʻole “uaea haʻalulu.”

Hoʻopili ka welding i nā ʻāpana āpau i ka papa ponoʻī, no laila e hana lākou inā e neʻe ka papa.
